Post-operative face-up or face-down positioning after silicone oil tamponade in retinal surgery: results of a retrospective study

Objective: To compare the complications related to silicone oil, and anatomical and functional outcomes in patients nursed in different postoperative positionings after pars plana vitrectomy with silicone oil injection in retinal surgery. Method: The retrospective cohort study was conducted at the Department of Ophthalmology, King AbdulAziz Medical City, Riyadh, Saudi Arabia, and comprised data of patients who underwent pars plana vitrectomy with silicone oil tamponade from January 2016 to October 2022. The patients were divided into two groups depending on how they were nursed in the postoperative period. Group A patients were nursed in postoperative face-down positioning and group B patients were nursed in the face-up position. Complications related to silicone oil tamponade, visual outcomes and anatomical results were compared between the groups. Data was analyzed using SPSS 26. Results: Of the 157, 97(62%) were males and 60(38%) were females. The overall mean age was 53±20 years. Group A had 87(55.4%) patients, while group B had 70(44.6%). There were 185 eyes involved; 104(56.2%) in group A and 81(43.8%) in group B. Overall, mean postoperative follow-up duration was 25±19 months. Migration of silicone oil in the anterior chamber was more common in group A (p=0.470). Pupil block glaucoma was seen in 2(1.9%) eyes in group A only.Silicone oil-related complications, functional outcomes and anatomical outcomes were non-significantly different between the grpups (p>0.05) except a weak significant difference with respect to redetachments after removal of silicone oil (p=0.047). Conclusion: There was no difference seen in terms of complications as well as anatomical and physiological outcomes related to silicone oil tamponade in face-down or face-up postoperative positioning after pars plana vitrectomy with silicone oil tamponade for complicated retinal detachment surgery. Key Words: Silicone oil, Face-down positioning, Macular folds, Epiretinal membranes, Pblock glaucoma, Silicone oil in anterior chamber.

Transretinal puncture with a 41G cannula for posterior residual subretinal fluid in fovea-off retinal detachments treated by vitrectomy VS fluid tolerance VS other conventional drainage techniques: a comparative study.

To compare functional and anatomical outcomes between posterior drainage of residual fluid using a 41G cannula, fluid tolerance (R-SRF), and conventional complete drainage methods, including removal through peripheral retinal breaks (PRB), perfluorocarbon liquid (PFCL), and posterior retinotomy (PR). In this retrospective, multicenter study, we evaluated cases for visual acuity (VA) at 3 months of follow-up. Secondary outcomes included surgical success, postoperative metamorphopsia, shifts, full-thickness folds (FTF), optical coherence tomography (OCT) parameters, and safety. Subgroup analyses were also conducted. VA did not differ significantly between the three main groups. Subgroup analyses revealed worse VA for PR with 1.131 LogMAR (20/270 in Snellen conversion, p=0,002), with significantly more grade C proliferative vitreoretinopathy (PVR, 40.0%, p=0,003). R-SRF tended to offer better secondary outcomes, without statistical significance except for postoperative epiretinal membrane (ERM, 30.8%, p=0,041). Subgroup analyses found significantly more shifts with PFCL (91,7%, p=0,036). No cases of postoperative FTF or macular holes were observed with the 41G. Our study introduced the 41G technique, indicating favourable outcomes for fovea-off retinal detachments. Nevertheless, fluid tolerance appeared to be the best option, offering a cost-effective and faster method, with an optimal microstructural profile and VA comparable to that of complete drainage techniques.

Sacrocolpopexy: The Way I Do It.

Sacrocolpopexy (SCP) is an established surgical procedure for apical vaginal vault prolapse. There remains significant variation amongst surgeons in both the surgical steps and concomitant surgeries utilised when undertaking an SCP. This review article is aimed at summarising the evidence and providing a detailed update of SCP in modern practice, reviewing contemporary evidence behind its indications, efficacy, outcomes, surgical steps, and complications. Sacrocolpopexy remains the gold standard for post-hysterectomy apical prolapse based on good long-term outcomes, patient satisfaction and low complication rates. SCP with concomitant total hysterectomy is not recommended owing to high rates of mesh exposure. The laparoscopic approach remains the preferred option in terms of low morbidity, quicker recovery and lower cost than alternative access options. For optimal outcomes an SCP should be performed with monofilament mesh, using absorbable sutures and with a paravaginal repair for cystocele. Although SCP has become increasingly utilised for apical prolapse, its established efficacy regarding anatomical outcomes, patient satisfaction, and complications is in the context of post-hysterectomy prolapse. SCP with concomitant total hysterectomy has higher rates of mesh exposure. The efficacy and safety of SCP with sub-total hysterectomy or hysteropexy have not been clearly established and require further assessment through well-designed, rigorous randomised controlled trials.

Comparative analysis of pre-operative findings and post-operative outcomes in primary and secondary macular holes at a tertiary eye hospital in South India

PurposeThis study aimed to compare demographics, clinical characteristics, and post-surgical outcomes between idiopathic and secondary full-thickness macular holes (MHs).MethodsA retrospective analysis of 348 eyes from 339 patients treated between June 2017 and December 2023 was conducted. The study included both idiopathic and secondary MHs, excluding cases where surgery was not performed or lacked sufficient follow-up. Demographic data, visual acuity (VA), ocular characteristics, and optical coherence tomography measurements were analyzed.ResultsIdiopathic MHs were identified in 308 eyes (89%), and secondary MHs in 40 eyes (11%). Idiopathic MH patients were older (mean age: 68.26 vs. 60.13 years; p = 0.001) and more commonly female (63% vs. 40%; p = 0.005). Post-surgical closure was achieved in 86% of all MHs, with a median VA improvement of 15 ETDRS letters (3 Snellen lines). However, secondary MHs had a lower closure rate (67% vs. 89%, p = 0.001) and less VA improvement (2 lines vs. 3 lines, p = 0.001) compared to idiopathic MHs. Significant differences in maximal basal diameter and diameter hole index were noted between the groups.ConclusionsSecondary MHs, accounting for 11% of surgical cases, show poorer anatomical and visual outcomes than idiopathic MHs. Despite lower success rates, early surgical intervention in secondary MHs is recommended to enhance outcomes. Differentiating between idiopathic and secondary MHs is crucial for optimal management.

Long-Term Functional Outcomes of Retinal Detachment Due to Acute Retinal Necrosis: A Case Series.

Objectives: To evaluate the long-term anatomical and functional prognosis of patients with retinal detachment (RD) secondary to acute retinal necrosis (ARN) treated with pars plana vitrectomy (PPV). Methods: This retrospective case series included 21 eyes from 21 patients with RD secondary to ARN. The study analyzed vitreous or aqueous biopsy results, the impact of antiviral therapy, time to retinal detachment, changes in visual acuity (VA), and anatomical and surgical outcomes. All cases underwent 23-gauge PPV with silicone oil tamponade, and an episcleral encircling band was used in 11 cases. All patients received systemic antiviral therapy at diagnosis. Results: Retinal reattachment was achieved in 91% of cases during follow-up, with an average follow-up period of 39.5 ± 36.8 months. The average time from ARN diagnosis to RD onset was 33.3 ± 27.5 days. VZV was detected in 10 eyes through PCR analysis. Significant differences in visual prognosis were found between macula-off and macula-on RD (p = 0.048). Eyes with optic nerve head inflammation had worse final VA (p = 0.010). No significant difference was observed between preoperative VA and VA at the end of follow-up (p = 0.665). Conclusions: VZV was the primary virus associated with ARN-related RD. Early involvement of the macula and optic nerve in retinitis negatively impacted the final visual prognosis.

Influence of foveal glial tissue after macular hole surgery on outer retinal restoration and visual acuity

Purpose: To investigate the impact of foveal glial tissue on the anatomical and functional results after macular hole (MH) surgery. Methods: This study included 141 consecutive eyes that underwent successful vitrectomy for full-thickness MH between January 2015 and December 2022. The best-corrected visual acuity (BCVA) and the length of outer retinal defects were evaluated preoperatively and at 6 months postoperatively. MH with retinal detachment, recurrent MH, and traumatic MH were excluded. Multiple regression analyses were conducted on outer retinal restoration and visual acuity using foveal glial tissue size, surgical technique of internal limiting membrane (ILM) peeling or inverted ILM flap, and high myopia as explanatory variables. Results: Analyses revealed that the foveal glial tissue significantly limited the outer nuclear layer (ONL), external limiting membrane (ELM) restoration, and ellipsoid zone (EZ) restoration as well as BCVA improvement (r = −0.380, p < 0.001; r = −0.314, p = 0.035; r = −0.530, p = 0.015; r = −0.00027, p = 0.001; respectively). Meanwhile, the surgical technique and high myopia did not significantly affect the restoration of ONL, ELM, EZ, and BCVA after surgery. Conclusion: Foveal glial tissue after MH surgery attenuated ONL, ELM, and EZ restoration as well as BCVA improvement.

Comparative analysis of methods of surgical correction of post-hysterectomy pelvic organ prolapse

BACKGROUND: The incidence of prolapse after hysterectomy requiring surgical intervention is estimated at 36 cases per 10,000 women. A universal surgical treatment method for post-hysterectomy pelvic organ prolapse is lacking, prompting the need for new approaches. AIM: To comparatively analyze the results of laparoscopic sacrocolpopexy, sacrospinous fixation, and the developed new method of surgical correction of pelvic organ prolapse after hysterectomy. MATERIAL AND METHODS: This prospective non-randomized study included 57 patients with stage II, III, or IV symptomatic post-hysterectomy prolapse of the pelvic organs who were admitted at the clinical hospital RZD-Medicine in Tula, Russia, between August 2019 and September 2023. The first group (n=18) consisted of women who underwent surgical correction of post-hysterectomy pelvic organ prolapse in a newly developed method; the second group (n=19) included women who underwent laparoscopic promontofixation according to the conventional technique; and the third group (n=20) involved patients who underwent installation of an apical sling using a UroSling-1 mesh endoprosthesis (Lintex LLC, St. Petersburg). The patients’ quality of life was assessed using specialized validated questionnaires: Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire. Patients were asked to complete questionnaires before surgery and 12 and 24 months after surgical correction of PGP. The patients were invited for a follow-up examination after 1, 6, 12, and 24 months. RESULTS: The duration of the operation in the second group significantly exceeded the indicators of the first and third groups. The average duration of hospital stay of patients was 4.4±0.6 (95% CI: 4.1–4.7) bed days in the first group, 4.9±1.1 (95% CI: 4.6–5.3) in the second, and 4.6±0.6 (95% CI: 4.3–4.9) in the third. The differences were insignificant (p1–2=0.437; p1–3=0.137; p2–3=0.235). The anatomical results after 24 months at points Aa and Ba showed significant differences. At point Aa, p1–3=0.007 and p2–3=0.004, and at point Ba, p1–3=0.032 and p2–3=0.041. A comparative assessment of the questionnaire data before surgery and 12 and 24 months after surgery showed a significant improvement in the quality of life of patients in the three groups. CONCLUSION: The proposed method of correction of post-hysterectomy pelvic organ prolapse provides high anatomical and functional results and reduces the posibility of repeated surgical intervention for recurrence.

Pediatric macular hole associated with vitreoretinal traction on epiretinal lesions – a case report and literature review

Purpose: We describe a case of non-traumatic macular hole in a pediatric patient associated with numerous epiretinal lesions throughout the macula. Methods: A healthy 9-year-old girl presented to retina clinic with several months of blurry vision in the right eye. Clinically, there was a full-thickness macular hole with serous detachment and white epiretinal tufts. Spectral-domain optical coherence tomography confirmed the presence of the full-thickness macular hole with hyperreflective epiretinal proliferations in the right eye and an unremarkable left eye. Systemic work-up was negative. After a short period of observation, the patient underwent vitrectomy with internal limiting membrane peel and 14% C3F8 gas tamponade in the right eye. Multiple intraoperative samples were sent for further testing, which were also negative. Results: At one and six-month postoperative visits, examination showed successful closure of the full-thickness macular hole with resolution of the subretinal fluid and improved visual acuity. Conclusion: Non-traumatic macular holes in pediatric patients warrant systemic and ocular work-up, including fluorescein angiography and lab testing. Good anatomic and visual outcomes are generally seen with spontaneous and surgical closures of macular holes in this age group. Early vitrectomy with histological analysis of ocular samples should be considered in pediatric macular hole cases associated with vitreoretinal traction, especially those with epiretinal abnormalities.

Preoperative Evaluation, Informed Consent and Postoperative Care in Pediatric Vitreoretinal Surgery

In childhood, vitreoretinal surgery may be required due to trauma and some congenital or developmental disorders. Pediatric vitreoretinal surgery differs from that of adults in terms of etiology, anatomical and surgical characteristics, response to treatment and follow-up. This process has many challenges that require patient follow-up over many years as the child develops. Pre-operative preparation according to the age of the patient and the nature of the pathology will make it easier for the surgeon to manage all the processes. The consent of the child must be obtained in accordance with the child's cognitive abilities, in addition to the informed consent of the family. Despite surgical and technological advances in pediatric vitrectomy, anatomical and functional outcomes are worse than in adults. This article discusses pediatric vitreoretinal surgery in terms of preoperative preparation, informed consent and follow-up.

Corneal stromal lenticule transplantation for the treatment of congenital optic disc pit maculopathy : a case report and review

BackgroundCongenital optic disc pit (ODP) is a relatively uncommon congenital anomaly of the optic disc, which seriously affects the patient’s vision when combined with optic disc pit maculopathy(ODP-M). Currently, the treatment of ODP-M remains a clinical challenge and a focus of research.Case presentationA boy had a pit in the inferotemporal segment of the optic disc with ODP-M. Optical Coherence Tomography(OCT) showed ODP and serous retinal detachment. He was treated with pars plana vitrectomy(PPV), followed by Corneal Stromal Lenticule (CSL) sealing and C3F8 tamponade. In the end, significant anatomical improvement was achieved, and the Best Corrected Visual Acuity(BCVA) was improved.ConclusionsThe CSL transplantation may be a viable therapeutic option for improving ODP-M with stable anatomical and functional result. However, more cases and longer follow-up are needed to confirm the safety and effectiveness of the technology.

Efficacy and safety of treat-and-extend intravitreal brolucizumab in naive and switched patients with macular neovascularization: one-year follow-up study

Backgroundto analyze, at one year, the efficacy and safety of treat-and-extend (T&E) intravitreal (IV) Brolucizumab in patients affected by macular neovascularization (MNV). Both naïve and previously treated (i.e., switched) patients were included, and the data from the two groups were compared.Methodsanatomical (i.e., central subfoveal thickness, CST; presence of fluid), functional (i.e., best corrected visual acuity, BCVA) and treatment-related (i.e., number of IV injections within the study period; number of patients reaching a 12-weeks interval between treatments) data from 41 eyes of 41 subjects (20 naïve and 21 switched) were analyzed. Patients were treated with 3 monthly IV injections followed by a T&E regimen based on a disease activity assessment performed at each scheduled IV treatment.Resultssignificant CST reduction (from 412.1 ± 115.8 to 273.2 ± 61.6; p < 0.05) and BCVA (mean; p) improvement were observed in the naïve group, while in the switched cohort, both parameters were almost stable. In the naïve and switched groups, 55% and 33.5% of patients, respectively, reached a 12-week IV interval at one year, with a mean of 6.55 ± 1 and 7.43 ± 0.68 IV treatments, respectively. One patient with mild anterior uveitis without sequelae was recorded.ConclusionIn patients with MNV, IV Brolucizumab injections following a T&E regimen demonstrated great efficacy and a good safety profile, with greater anatomical and functional results in naïve patients.Trial registrationThis study was approved by the Local Ethics Committee (protocol number 155/2020, general registry number n°11486, InterHospital Ethics Committee, San Luigi Gonzaga Hospital, Orbassano, Italy).

Surgical Reconstruction in Malignant Eyelid Tumors.

To report the histopathological subtypes of malignant eyelid tumors treated surgically in the author's clinic and to present the author's graft and flap preferences in the reconstruction of the eyelid defect after surgical excision. This retrospective study included 33 patients who underwent malignant eyelid tumor excision, followed by eyelid reconstruction. A frozen section was performed during surgery to assess surgical margins in all patients. Demographic characteristics, histological classification, localization, and size of the tumor, postoperative defect size, follow-up period, complications, and recurrence rate were recorded. Of the patients with a mean age of 66.6 ± 15.3 (range: 23-94), 15 (45.5%) were females and 18 (54.5%) were males. The lower eyelid was the most commonly involved site in 27 (81.8%) patients. Basal cell carcinoma was the most frequently diagnosed type of malignant cancer in 81.8% (n = 27) of the cases. Among the tumor subtypes, nodular type basal cell carcinoma was the most frequently observed subtype in 10 (30.3%) patients. Wide excision with different flap and graft techniques was performed in 26 (78.8%) patients with defect sizes of 40% or larger. In the author's study, the most preferred flap technique for anterior lamella reconstruction was the Tenzel semicircular flap (30.3% n = 10). The most frequently preferred flap for posterior lamella reconstruction was the Hughes tarsoconjunctival flap (30.3% n = 10). There were no flap or graft failures in any of the author's cases. In the treatment of malignant eyelid tumors, different local flap and graft techniques selected according to the size of the defect have successful anatomical results in reconstructive surgery after frozen section controlled excision.

Visual and anatomical outcomes following vitrectomy with subretinal tPA injection in patients with submacular haemorrhages secondary to wet AMD

Purpose: Submacular haemorrhages (SMHs) are most commonly associated with wet age-related macular degeneration (AMD) and their size and duration are strong prognostic factors for visual outcome. The aim of this audit was to evaluate outcomes of direct injection of submacular tissue plasminogen activator (t-PA) into these lesions during pars plana vitrectomy (PPV). Methods: All patients presenting to the Mater Misericordiae Hospital from January 2017 to December 2019 with large SMHs secondary to wet AMD who underwent this treatment were included for review. All ten patients underwent complete PPV, injection of 0.2ml (50µg) subretinal t-PA and air tamponade. Pre-operative and post-operative evaluations included visual acuity testing (VA), optical coherence tomography (OCT) and slit lamp examination. Results: Eight patients (80%) showed improvement of their VA, with 4 patients achieving a VA of ≤0.4 LogMAR (20/50). Six patients had a total clearing of the macular haemorrhage, with a further 2 having sub-total clearance. One patient subsequently developed a retinal detachment requiring oil tamponade. Conclusions: SMH secondary to wet AMD is a sight threatening event with a varied prognosis but in most cases, vitrectomy with subretinal t-PA injection results in improved anatomical and visual outcomes.

Vitrectomy combined with inverted internal limiting membrane flap insertion or single-layered flap covering technique for highly myopic macular holes with macular retinoschisis.

To investigate the anatomical and visual outcomes of inverted internal limiting membrane (i-ILM) flap insertion versus single-layered i-ILM flap covering in highly myopic macular holes (HMMHs) associated with macular retinoschisis (MRS). A retrospective study compared 23G vitrectomy with i-ILM flap insertion (30 eyes) or covering (31 eyes) in HMMH patients. Pre- and postoperative optical coherence tomography images and best-corrected visual acuity (BCVA) were evaluated. Macular hole schisis (MHS) was classified into three types based on the extent of outer layer schisis. Regression analysis identified predictors of closure rate and postoperative BCVA. The baseline data of the two groups were matched, including BCVA, axial length, and minimum linear diameter, except for a higher hole height in insertion group (P=0.038). After a mean follow-up of 11.7 months, type I closure rates were 83.3% (25/30) in the insertion group and 90.3% (28/31) in the covering group (P=0.335), respectively. The intact external limiting membrane in the covering group (7/28) was higher compared to the insertion group (1/28) finally (P=0.026). Final BCVA improved significantly in both groups (P<0.001), the BCVA was better in closed HMMHs in the covering group (P=0.011). Multivariate linear regression analysis revealed that preoperative BCVA (β=0.386, P=0.001) and MHS stage (β=0.309, P=0.004) were independent predictive factors for the final BCVA. The single-layered i-ILM flap covering favored foveal structure recovery and provided a better visual prognosis in closed HMMHs compared with insertion. The preoperative BCVA and MHS stage were independent predictors of visual outcomes in patients with HMMHs.

Predictive relevance of optical coherence tomography indices in conjunction with visual acuity and surgical outcomes of idiopathic macular hole

Idiopathic macular hole (IMH) is a condition that arises from a combination of interactions among several forces on the fovea, remarkably from vitreous traction in the anteroposterior and tangential directions. Recent studies have highlighted the significance of microincision vitrectomy surgery, and IMH surgery was performed with minimal invasiveness, and visual improvement was an expected outcome. This study aimed to observe the pre-operative optical coherence tomography (OCT) indices correlated with visual acuity in the closure of IMH after surgery. Primarily, the findings were associated with clinical characteristics, including OCT indices, change in best corrected visual acuity (BCVA), clinical factors associated with IMH closure, and prognostic factors for the visual outcomes. This retrospective study included pre- and post-operative BCVA and OCT indices of 110 eyes with IMH. Each OCT variable was subjected to stepwise regression analysis regarding therapeutic factors that predict the need for IMH closure. Our results revealed that the hole form factor (HFF, r = 0.196), macular hole index (MHI, r = 0.669), and tractional hole index (THI, r = 0.085) had a positive correlation with visual acuity. However, basal hole diameter (BHD, r = −0.696) and minimum hole diameter (MHD, r = −0.407) showed a negative correlation. Out of them, HFF, MHI, BHD, and MHD were observed to be statistically significant (p < 0.05). The mean follow-up time was 149 ± 63.22 (85–300) days. The mean baseline BCVA was 0.75 ± 0.44 logMAR (Logarithm of the Minimum Angle of Resolution) units, which was improved to 0.29 ± 0.27 logMAR units at the final follow-up. The surgical success closure rate was 100 % among subjects with IMH. In conclusion, OCT indices were significant indicators of visual success rates in IMH, and OCT measurement could be employed as a single key index in predicting the IMH closure rate. Also, our findings suggested that OCT indices could be utilized as a safe and effective predictor of visual and anatomical outcomes in the case of IMH.

Hysterectomy versus Uterine Preservation for Pelvic organ prolapse Surgery (HUPPS): A prospective cohort study

One in five females will have surgery to treat pelvic organ prolapse in their lifetime. Uterine-preserving surgery involving suspension of the uterus is an increasingly popular alternative to the traditional use of hysterectomy with vaginal vault suspension to treat pelvic organ prolapse; however, comparative evidence with native tissue repairs remains limited in scope and quality. To compare 1-year outcomes between hysterectomy-based and uterine-preserving native tissue prolapse surgeries performed through minimally invasive approaches. We used a non-randomized design with patients self-selecting their surgical group to integrate a pragmatic, patient-centred, and autonomy-focused approach. Participants chose between uterine-preserving surgery or hysterectomy-based surgery, guided by neutral, evidence-based discussions and individualized decision-making, with support from fellowship-trained urogynecologists. Inverse probability of treatment weighting based on high-dimensional propensity scores was used to balance baseline differences across surgical groups in an effort to resemble a randomized clinical trial. A prospective cohort study of 321 participants with stage ≥2 prolapse involving the uterus who desired surgical treatment were recruited between 2020 and 2022 and followed to 1 year (retention >90%). Patients chose to receive uterine-preserving POP surgery through hysteropexy (n=151) or hysterectomy with vaginal vault suspension (n=170; reference group), with repair of anterior and/or posterior prolapse if indicated. The primary outcome was anatomic prolapse recurrence within one year, defined as apical descent ≥50% of the total vaginal length. Secondary outcomes were peri-operative, functional, clinical, and healthcare outcomes measured at 6 weeks and 1 year. Inverse probability of treatment weighted linear regression and modified Poisson regression were used to estimate adjusted mean differences (aMD) and relative risks (aRR), respectively. Apical anatomic recurrence rates at 1 year were 17.2% following hysterectomy and 7.5% following uterine-preservation, resulting in an adjusted relative risk of 0.35 (95% CI 0.15, 0.83). Uterine-preserving surgery was associated with shorter length of surgery (aMD -0.68 hours [-0.80, -0.55]) and hospitalization (aMD -4.34 hours [-7.91, -0.77]), less use of any opioids within 24 hours (aRR 0.79 [0.65, 0.97]), and fewer procedural complications (aRR 0.19 [0.04, 0.83]) than hysterectomy. Up to 1 year, uterine-preserving surgery was associated with lower risk of composite recurrence (stage ≥2 prolapse in any compartment or retreatment; aRR 0.47 [0.32, 0.69]) than hysterectomy, driven by anatomic outcomes. There were no clinically meaningful differences in functional or healthcare outcomes between surgical groups. This study adds real-world evidence to the growing body of research supportive of uterine-preserving surgery as a safe, efficient, and effective alternative to hysterectomy during native tissue prolapse repair. Given mounting evidence on safety, efficiency, and effectiveness of uterine-preserving surgery and its alignment with the preferences of approximately half of patients to keep their uterus, the standard of care should include routine offering and patient choice between uterine-preserving and hysterectomy-based surgery for pelvic organ prolapse.

The Wisconsin silicone oil study (report #1): anatomical and functional outcomes of repair of retinal detachment with proliferative vitreoretinopathy.

Silicone oil (SO) is a long-term tamponade for repair of complex retinal pathology but has limitations including late redetachment. This study describes our experience with SO tamponade for repair of retinal detachment with proliferative vitreoretinopathy (PVR), with attention to anatomic and functional outcomes. Retrospective consecutive case series of eyes with retinal detachment (RD) complicated by proliferative vitreoretinopathy (PVR) receiving SO tamponade at the University of Wisconsin between 2013 and 2019. Group 1 defined as primary SO placement; Group 2 had SO placed after failing prior retinal detachment repair. Inclusion criteria of SO placement for repair of RD with PVR was met for 117 eyes. The final reattachment rate was 84% for all eyes, with no difference between Groups 1 and 2. Vision improvement was 2.1 lines for Group 1 (p = 0.06 from baseline) and 4.6 lines for Group 2 (p < 0.0001). The mean number of silicone oil placements was 1.4. Less improvement in vision was noted with repeat SO placement, though overall functional vision of 5/200 or better was achieved in 63.2% of patients. SO tamponade allows long-term anatomical stabilisation and substantial vision recovery in eyes with retinal detachment complicated by PVR. Rates of anatomic and functional success have improved significantly when compared to prior studies using oil tamponade for repair of PVR.

Lamellar scleral patch autograft after ballistic accident: A case report

Scleral graft has been used in clinical situations including perforating eye trauma to treat traumatic scleral dehiscence. A 28-year-old male patient presented for a painful left eye following a firearm-related injury few hours ago. Visual acuity was limited to light perception with a 2 mm wide, oval-shaped inferior scleral gap. Due to the size of the scleral defect, we decided to perform a scleral autograft. The graft was fashioned from the inferonasal sclera, deposited over the recipient hole, and secured with 10–0 nylon sutures on the corneal and scleral sides of the surgical bed with favorable anatomical and refractive outcomes.

Anatomical Study of Abdominal Wall Muscle Innervation to Optimize Retroperitoneal Vascular Approach

INTRODUCTIONDifferent surgical approaches are used in aortic surgery. Retroperitoneal approaches can result in abdominal wall weakness and flank bulging. These approaches often require dissection of the anterolateral or anteromedial muscles of the abdominal wall. During dissection, the underlying nerves are at great risk of injury, which induces significant complications in abdominal wall muscles. Few studies have been conducted to minimize the risk of injury to these nerves. OBJECTIVESThis study aims to describe the trajectory of abdominal muscle motor nerves and their relationship to ribs and other anatomical landmarks. The secondary objective is to optimize surgical approaches by preserving the nerves. METHODWe conducted 12 dissections on fresh cadavers. Nerve trajectories, communication between the intercostal nerves (9th–10th–11th) and the subcostal nerve (12th), and the distance from the nerve to the estimated projection point of intersection with the abdominal midline, umbilicus, and iliac crest was recorded. RESULTSOur dissections identified the 12th subcostal nerve as the largest nerve. The 11th intercostal nerve exhibits more accessory branches than other nerves. Multiple communications and branches were observed between the 10th and 11th intercostal nerves and between the 11th and 12th nerves in the region from the anterior axillary line to the mid-clavicular line. The estimated projection point of intersection with the midline was 7.92 ± 1.24 cm supraumbilical for the 9th intercostal nerve, 3.92 ± 1.18 cm supraumbilical for the 10th, 1.08 ± 1.52 cm at the umbilical level for the 11th, and -3.33 ± 0.83 cm infraumbilical for the subcostal nerve. The distance between the iliac crest and the iliohypogastric nerve in the lateral jackknife position was 2.54 ± 0.65 cm. The 11th nerve had an angle in relation to the rib of between -45° and -10° (average: -24.6°), and the 12th nerve had a similar angle of between -30° and 0° (average: -18.3°). For the 11th nerve, the distance was between 0 and 5.5 cm (average: 2.92 cm); for the 12th nerve, it was between 0 and 3.0 cm (average: 1.71 cm). CONCLUSIONTo preserve the 11th nerve, the optimal approach is a straight incision starting from the upper edge of the 11th rib towards the midline, 4 cm above the umbilicus; for the 12th nerve, the optimal approach is a straight incision starting from the upper edge of the 12th rib towards the midline, 1 cm below the umbilicus; for the iliohypogastric nerve, the optimal approach is an incision close to the iliac crest at a distance <1.5 cm. The estimated projection point of intersection between the nerve directions towards the midline can indicate the anatomical trajectory of nerves. A nerve projection towards the midline can provide valuable information about the anatomical location of a nerve. This study has utility in optimizing surgical approaches. A clinical study can confirm these anatomical results.
