Risk factors for receiving both scleral buckle and glaucoma drainage device in children

We conducted a retrospective review of patients (< 18 years) between 2013 and 2021 to determine risk factors of pediatric patients receiving a glaucoma drainage device (GDD) needing a scleral buckle (SB) and vice versa. The first population underwent an SB placement with no prior GDD. The second underwent a GDD implantation with no prior SB. We analyzed 133 eyes in the SB-first group. The common indications were retinal detachment associated with a syndrome/disease (41.2%), blunt trauma (21%), and non-syndromic pathologic myopia (11%). Twelve eyes (9%) required subsequent GDD implantation with a mean time to reoperation of 19.73 months (median 2.3 months). Eyes with trauma had a 5-fold risk (hazard ratio [HR] 4.81, p = 0.0069) of requiring a subsequent GDD. Each additional glaucoma medication before initial SB surgery increased the risk by 1.81 (p = 0.0096). 135 eyes were in the GDD-first group. Four eyes (3%) required a subsequent SB. The mean time to reoperation was 17 months (median 9.2 months). There was a statistically significant association with trauma (HR 12.3, p = 0.0341) only. Pediatric eyes with a history of trauma and/or multiple glaucoma medications before intervention have a high risk of requiring both an SB and GDD.

Silicone on the Move: Migratory Siliconoma After Retinal Surgery Report of a Case and Review of the Literature.

Silicone granulomas, or "siliconomas," are the common foreign-body inflammatory responses to injected silicone material. In rare cases, siliconomas develop remotely from the original site of injection, secondary to silicone migration. If a history of silicone injection is not noted, such lesions risk misdiagnosis (possibly as infection or malignancy). Intraocular silicone oil is commonly used in retinal detachment surgery, with occasional reports of granulomatous responses after its application in this context. Here, we report a 66-year-old man who developed a periocular silicone granuloma years after scleral buckle surgery for a detached retina and summarize the literature of similar reports of migratory siliconoma.

Cost Analysis of Scleral Buckle and Pars Plana Vitrectomy for Retinal Detachment Surgery.

To compare the cost and utility of scleral buckle (SB) and pars plana vitrectomy (PPV) techniques for repairing moderately complex rhegmatogenous retinal detachment (RRD). A cost-utility analysis was conducted using data from the Primary Retinal Detachment Outcomes Study (PRO) and a study conducted by the author. Total costs, patient utility over a lifetime, and cost per quality-adjusted life year (QALY) were calculated for each surgical procedure. The cost of scleral buckle surgery was €287.93, with an estimated lifetime QALY of 7.49. Costs per QALY were €38.44. According to the PRO study and Belin et al, total costs were $5975, with a lifetime QALY of 5.4 and costs per QALY of $1106. The cost of pars plana vitrectomy (PPV) was €1468.26, with an estimated lifetime QALY of 6.84 and costs per QALY of €214.65. Based on the PRO study and Belin et al, total costs were $8125, with a lifetime QALY of 4.7 and costs per QALY of $2196. Repairing moderately complex RRD presents a highly cost-effective profile for both SB and PPV techniques, well below recommended QALY thresholds. SB demonstrated a slightly more favorable profile compared to PPV.

Anatomic and Visual Outcomes of Scleral Buckle in Primary Rhegmatogenous Retinal Detachment in the Era of Pars Plana Vitrectomy

Introduction: To determine the presenting clinical characteristics of patients with rhegmatogenous retinal detachment (RRD) who underwent scleral buckling and the impact on final visual outcomes and to determine the postoperative primary attachment rate, complications, and subsequent management. Methods: This retrospective observational study comprised patients with RRD who had scleral buckling surgery from January 2016 to December 2021 with a minimum follow-up of 6 months. Results: The study comprised 307 eyes of 290 patients; 97% of eyes were phakic. Primary anatomic attachment was achieved in 93% of eyes. Macula-on detachment had a significant relationship with visual gain, while age, refractive status, number of breaks, configuration of the detachment, traumatic etiology, and lens status did not. Eyes with recurrent detachment did not have a significant visual gain after subsequent pars plana vitrectomy (PPV). Conclusions: Most eyes that underwent scleral bucking were phakic. Macular status played a significant role in the visual prognosis. The primary anatomic attachment rate after scleral buckling surgery is comparable to that after PPV. Thus, scleral buckling is far from being a procedure of the past. Multiple breaks, inferior detachments, and traumatic etiology do not appear to adversely affect the visual outcomes. Multiple vitreoretinal surgeries may not result in a visual gain in cases of recurrent detachment.

Evaluation of the ocular surface with keratograph 5M analysis after scleral buckle surgery in patients with retinal detachment

ABSTRACT Background This study aims to evaluate the ocular surface health with oculus keratograph 5M (Oculus, Wetzlar, Germany) in patients, 4–6 weeks after the SB surgery. Research design and methods Adult patients with RRD who underwent SB surgery were enrolled. Subjects with the existence of any concomitant ophthalmologic diseases or topical medications that can affect the ocular surface were excluded. The ophthalmic examination and corneal imaging with oculus keratograph 5M were conducted 4–6 weeks after the surgery, following discontinuation of all topical medications. The ocular surface parameters were compared between the surgical and other eyes. Results The results showed a statistically significant difference in the ocular surface profile, including the tear meniscus height (TMH), Non-invasive keratograph breakup time (NIKBUT), Meibography, and Redness scores, between the surgical eye and the other eye four to six weeks after the procedure. Conclusion In this study, we showed convincing evidence of the role of keratography imaging in the objective evaluation of the ocular surface 4–6 weeks after SB surgery. We depicted that SB surgery disturbs the ocular surface homeostasis significantly, which can cause ocular discomfort as well as decrease visual function in patients in the post-up periods.

Anesthesia Techniques for Vitreoretinal Surgery in the United States: A Report from the Multicenter Perioperative Outcomes Group Research Consortium

PurposeTo explore the patterns of anesthesia use and their determinants during vitreoretinal (VR) surgeries in academic and community hospitals across the US, using data from the Multicenter Perioperative Outcomes Group (MPOG). DesignA retrospective, multicenter, cohort study. MethodsWe queried the MPOG database of 107,066 patients undergoing VR surgeries. Patients (≥18 yrs.) undergoing VR surgery with monitored anesthesia care (MAC) or general anesthesia (GA) from January 1, 2015, to December 31, 2021 were included. Patient-level, case-based, and institutional-level covariates were collected. We performed multivariable mixed-effects models to determine predictors of anesthesia type use. The primary outcome was the type of anesthesia (MAC or GA) used during VR surgeries. As a secondary outcome, MAC cases were further classified based on the additional use of sedation into MAC with or without sedation. ResultsWe found that 67.45% of VR surgery cases received MAC, and 73.63% of institutions administered MAC to more than half of cases. Random effect modeling revealed that 47.76% of the variation in MAC use was attributed to institutions. A trend toward increased use of MAC with increasing age was observed. Patients diagnosed with chronic pulmonary disease, liver disease, or a history of drug abuse were less likely to receive MAC. Conversely, we found that patients with reported alcohol abuse disorder, diabetes with complications, and those with American Society of Anesthesiologists (ASA) physical status of 4 (vs. 1, 2, or 3) were more likely to use MAC. Compared to non-complex VR surgeries, there was a notably decreased likelihood of MAC use in complex PPV (P = 0.004), PPV + scleral buckle (SB) for retinal detachment (P < 0.0001), and primary SB surgery (P < 0.0001). ConclusionsApproximately 2/3 of VR anesthesia is under MAC, but GA is still preferred for SBs, complex vitrectomy, and younger patients. We show that large interinstitutional variation for using MAC in practice exists.

Evaluation of macular integrity, after retinal detachment surgery, using MAIA microperimetry

Background and objectiveTo describe visual function, macular integrity, and fixation stability using MAIA microperimetry (macular integrity assessment) after retinal detachment surgery. Evaluate if there are statistically significant differences between surgical approaches. Materials and methodsA prospective, comparative, interventional study was conducted, recruiting a total of 21 patients with rhegmatogenous retinal detachment and macula-off. Eleven patients underwent surgery using pars plana vitrectomy (PPV), and 10 patients underwent scleral buckle surgery. Clinical examinations and optical coherence tomography (OCT) were performed post-surgery. MAIA microperimetry was conducted at 6 months. ResultsBest-corrected visual acuity (BCVA) and the number of letters read improved over time in the operated eye but did not reach the level of the control eye (p = 0.001). No significant differences were found between the two surgical approaches in BCVA (p = 0.230) or the number of letters read (p = 0.608). Macular integrity in the operated eye did not match that of the control eye in both procedures (p = 0.05). No differences were detected between the two surgeries, either in macular integrity (p = 0.512) or fixation stability (p = 0.835). ConclusionsFollowing retinal detachment surgery, a decrease in BCVA and the number of letters read occurs, which does not reach the level of the control eye. No significant differences were observed between the two surgical approaches. Macular integrity in the operated eye does not match that of the control eye.

The necessity and role of scleral buckling for rhegmatogenous retinal detachment.

With a decline in the use of scleral buckling for rhegmatogenous retinal detachment (RRD) repair in recent years, this review seeks to provide a summary of the most recent research findings regarding the role of scleral buckling in the repair of RRD. Many recent studies have compared visual and anatomic outcomes between scleral buckling and pars plana vitrectomy (PPV) for RRD repair. Some suggest superior outcomes with primary scleral buckling, particularly in younger, phakic patients, and in association with other risk factors that we review. Children do best with primary scleral buckling surgery. Functionally, scleral buckling may also result in lower rates of retinal displacement compared to PPV. When PPV is necessary, a supplemental buckle may benefit certain patients, while the advantage remains unclear in other clinical scenarios and necessitates further investigation. Scleral buckling is an important technique for the repair of RRD and it is crucial to continue training retina surgeons in this technique to maximize patient outcomes.

Outcome of Glaucoma Management in Sturge-Weber Syndrome: Case Series

Objective: To report the clinical findings and outcome of treatment for developmental glaucoma from Sturge-Weber syndrome in four consecutive children managed at a child eye health tertiary facility in Ibadan, Nigeria. Methods: A retrospective case series of four children with Sturge-Weber syndrome (SWS) and developmental glaucoma who underwent surgical treatment for glaucoma over a 3-year period. Information on patients’ sociodemographic data, clinical features, and management are described. Results: Four male children, aged between 7 weeks and 11 years, with unilateral developmental glaucoma and varying extent of port-wine stain were included in the study. The primary surgery in three patients was trabeculectomy, while the fourth patient received a glaucoma drainage device. Shallow anterior chamber, choroidal effusion, and cataract were complications of glaucoma surgery observed. Secondary surgeries performed include anterior chamber reformation, suturing of leaking peritubular scleral channel, sclerotomy and fluid drainage, bleb needling, cataract surgery, and scleral buckle surgery. At the 1-year follow-up visit, one eye had complete success, one eye had qualified success, while the other two had treatment failure. Conclusion: The outcome of management of glaucoma associated with Sturge-Weber syndrome is modest. Though rare, SWS can cause significant ocular and systemic morbidity. Complications of therapy may be encountered, and multiple surgical interventions may be required for optimal management.

Non-contact wide-field viewing system-assisted scleral buckling surgery for retinal detachment in silicone oil-filled eyes.

To evaluate scleral buckling (SB) surgery using a non-contact wide-field viewing system and 23-gauge intraocular illumination for the treatment of rhegmatogenous retinal detachment in silicone oil (SO)-filled eyes. Totally 9 patients (9 eyes) with retinal detachment in SO-filled eyes were retrospectively analyzed. All patients underwent non-contact wide-field viewing system-assisted buckling surgery with 23-gauge intraocular illumination. SO was removed at an appropriate time based on recovery. The patients were followed up for at least 3mo after SO removal. Retinal reattachment, complications, visual acuity and intraocular pressure (IOP) before and after surgery were observed. Patients were followed up for a mean of 8.22mo (3-22mo) after SO removal. All patients had retinal reattachment. At the final follow-up, visual acuity showed improvement for 8 patients, and no change for 1 patient. The IOP was high in 3 patients before surgery, but it stabilized after treatment; it was not affected in the other patients. None of the patients had infections, hemorrhage, anterior ischemia, or any other complication. This new non-contact wide-field viewing system-assisted SB surgery with 23-gauge intraocular illumination is effective and safe for retinal detachment in SO-filled eyes.

Silicone Oil Tamponade for Therapy of Primary Retinal Detachment in Patients Who Live at High Altitudes.

Uncomplicated rhegmatogenous retinal detachment (RRD) is mainly treated with vitrectomy and gas tamponade or, alternatively, scleral buckling surgery. However, gas tamponade inflates at high altitudes, causing significant complications. Silicone oil (SO) tamponade volume is unaffected by atmospheric pressure and may be used in patients who live or must undertake travel at high altitudes. To determine the anatomical and functional outcomes after pars plana vitrectomy (PPV) with SO tamponade in primary uncomplicated RRD. Twenty-eight consecutive cases of patients operated between January 2017 and December 2022 in Jules-Gonin University Eye Hospital in Lausanne were included in this retrospective study. All patients had a follow-up of at least 3 months after SO removal. Primary reattachment was achieved in all 28 eyes. Mean follow-up was 17.2 months (range: 3 - 51 months) after SO removal. Mean age at the time of intervention was 60 years (range: 21 - 80 years). Vision was stabilized or improved in 27 eyes (96%). One patient demonstrated a slight visual acuity decrease due to cataract formation at the last follow-up. In all patients, SO was removed 2 to 5 months after primary repair. In 14 of the 21 phakic patients, concomitant cataract surgery was performed. No surgical complications were encountered. Postoperatively, 5 (18%) patients had ocular hypertension, presumably steroid related, that was successfully controlled with topical treatment. PPV with SO injection seems to be a safe and efficient surgical approach in the treatment of primary uncomplicated RRD in patients living at high altitudes and was associated with good anatomical and functional outcome in our series. However, the need for a follow-up surgery to remove SO should be weighed in these cases.

Comparative study of the three-dimensional perception of videos recorded on a "Do it yourself" three-dimensional recording assembly versus the conventional recording system.

To develop an indigenous "Do it yourself" (DIY) three-dimensional (3D) ophthalmic surgery recording system and validate the perception of stereopsis using it. A cross-sectional survey of practicing ophthalmologists with post-postgraduation experience of at least 5 years for perception of stereopsis for three different surgeries was performed; cataract, retinal detachment, and intravitreal drug injection were recorded on DIY assembly, viewed on VRBOX and using laptop videos and pseudo 3 d videos as control. The laptop videos and 3D VR Box videos received higher ratings for stereopsis than the pseudo 3D videos. The parameters that received significantly higher ratings on the 3D VR Box viewing were instrument's position relative to the ocular surface in cataract surgery, anterior chamber depth during capsular staining, ophthalmic visco-surgical device injection, capsulorhexis, phaco tunnel depth, movement of nuclear fragments in the anterior chamber, and intra-ocular lens tilt in the capsular bag during cataract surgery ( P < 0.05). In scleral buckling surgery, the parameters that were significantly rated higher on VR Box were globe contour, separation of the scleral plane from muscle, and explant plane ( P < 0.05). Furthermore, the depth of the needle in the vitreous cavity while administering intravitreal drug injection was also rated significantly higher on VR Box ( P < 0.05). However, the ratings for the depth of corneal incision, depth of scleral incision, overall color, and overall quality were not different statistically when compared between laptop and VR Box viewing. DIY 3D recording assembly offers a superior means of appreciating depth at various stages of cataract surgery, scleral buckling, and intravitreal drug injection when compared to laptop viewing and can serve as an effective tool for skill transfer.

Chandelier-assisted scleral buckle surgery - contact versus non-contact wide-angle viewing system (CAB-CNV): A retrospective, multicenter, clinical study.

To investigate and compare the anatomic and functional outcomes of chandelier-assisted scleral buckling (CASB) surgery using contact versus non-contact lens-based wide-angle viewing systems (WAVSs) in rhegmatogenous retinal detachment (RRD) patients. This was a retrospective, multicenter study evaluating the anatomic (reattachment rate) and visual acuity (VA) outcomes at 6 months post-CASB for primary RRD. Forty-seven RRD patients underwent CASB with a non-contact WAVS (Group C1) and 90 with a contact lens WAVS (Group C2). Preoperative parameters including myopia, macula-off RRD, posterior vitreous detachment, number of retinal breaks, and retinal dialysis as the etiology of RRD did not differ significantly between the two groups. The outcomes of retinal attachment (85.11% of C1 patients and 76.67% of C2 patients, P = 0.34) and final visual outcome (VA ≥6/12: C1 = 61.7%; C2 = 46.67%, P = 0.13) were also comparable. Furthermore, no significant difference in postoperative complications such as cataracts, glaucoma, infection, buckle exposure, and buckle failure was observed. Finally, both groups were comparable in terms of re-detachment rates (10.64% in C1 and 23.33% in C2, P = 0.11). The two WAVS approaches used in CASB surgery have comparable surgical and functional outcomes and postoperative complications. The operating surgeon can freely choose between these viewing platforms during the contemporary scleral bucking (SB) surgery without impacting the outcome.

Macular hole following scleral buckling for rhegmatogenous retinal detachment: a case series

BackgroundMacular hole (MH) development following scleral buckling (SB) surgery for rhegmatogenous retinal detachment (RRD) repair is rare. This study presents both full-thickness MH (FTMH) and lamellar MH (LMH) cases following SB for the treatment of RRD.MethodsClinical records of patients undergoing SB surgery for treatment of RRD at the Xi’an People’s Hospital (Xi’an Fourth Hospital) from January 2016 to December 2021 were reviewed, and cases with postoperative MH were selected. Clinical features and follow-up data were summarised, and possible causes were analysed.ResultsAmong 483 identified cases (483 eyes), four eyes (three male patients, one female patient) had postoperative MH, with prevalence, mean age, and mean axial length of 0.83%, 43.5 ± 10.66 years, and 29.13 ± 3.80 mm, respectively. All patients did not undergo subretinal fluid (SRF) drainage. The mean time for detecting MH was 26 ± 15.5 days postoperatively. Macula-off RRD with high myopia and FTMH combined with retinal re-detachment were diagnosed in three patients. One patient had macula-on RRD with outer LMH. The average follow-up duration was 7.25 ± 1.5 months. The FTMH closed successfully after reoperation, while the outer LMH closed without intervention. Visual acuity insignificantly improved or slightly decreased in all patients.ConclusionsPatients with high myopia combined with macula-off RRD might be more susceptible to FTMH, causing MH related retinal detachment. Additionally, LMH following SB was noted in patients with macula-on RRD. Therefore, we should raise awareness of MH following SB for RRD repair.

Efficacy of peribulbar bupivacaine at the end of surgery in the management of postoperative pain after scleral buckling.

To compare the efficacy of peribulbar bupivacaine with routine analgesics for pain management in patients undergoing scleral buckling. In total, 72 patients undergoing scleral buckling or combined with vitrectomy were enrolled in this study. Patients were randomized into two groups, each containing 36 patients. Patients of group A received 5 mL of bupivacaine (0.5%) injection at the end of surgery, whereas group B patients received routine analgesics. The postoperative pain score was assessed in the first 24 hours of the postoperative period with the visual pain analog score. Maximum postoperative pain scores were lower in patients receiving bupivacaine block (median: 3; range: 3-7) than in the control group (median: 5; range: 3-9). Pain scores in group A were lower than in the control group both at 3 and 6 hours after surgery, which was statistically significant ( P < 0.001). Four patients in group A and 17 patients in group B needed additional analgesia in the first 24 hours of the postoperative period. In addition, two patients in group A and seven patients in group B experienced episodes of nausea and vomiting in the first 24 hours of surgery. The results of this study suggest that the postoperative experience of patients undergoing scleral buckling surgery can be made more comfortable with the use of bupivacaine block at the end of surgery.

Potential Risk Factors for Ocular Pain in Patients Undergoing Multiple Intravitreal Injections of Anti-Vascular Endothelial Growth Factor.

To assess ocular pain in patients undergoing multiple intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) who have previous factors that may influence pain sensitivity. This is a prospective, observational, case series study involving patients who underwent multiple (≥3) pro re nata intravitreal injections of ranibizumab or aflibercept to treat any cause of chorioretinal vascular disease. Ocular pain was assessed by the numerical analog scale during intravitreal injection. For this study, the main variable was ocular pain and the secondary variables included age, sex, previous history of glaucoma, primary retinal vascular disease, severe dry eye history, trigeminal pain, scleral buckle surgery, collagen diseases, fibromyalgia, severe migraine history, pars plana vitrectomy, scleral thickness measurements, and type of anti-VEGF. In a total of 894 patients, 948 eyes (4822 intravitreal injections), 793 patients (88.6%) had ocular pain sensitivity between no pain to mild pain, 80 patients (8.9%) had moderate ocular pain, 15 patients (1.6%) had severe ocular pain, and 6 patients (0.7%) had extremely severe ocular pain. Patients with severe dry eye (p = 0.01) and previous history of scleral buckle surgery (p = 0.01) showed a significant correlation with ocular pain during intravitreal injection. Pars plana scleral thickness (>550 um) and diabetic neuropathy were associated with ocular pain but did not meet the criteria for statistical significance (p = 0.09 and p = 0.06, respectively). Dry eye and prior scleral buckle surgery may contribute to pain associated with intravitreal injection. These issues should be taken into consideration in patients undergoing multiple intravitreal injections.

Cataract Outcomes Following Scleral Buckle Surgery for Retinal Detachment.

To investigate refractive, visual, and safety outcomes of cataract surgery performed after scleral buckling (SB) for retinal detachment (RD). A chart review at an academic medical center identified eyes with history of SB followed by subsequent cataract extraction between 2010 and 2022. Eyes with less than 3 weeks follow-up, silicone oil at time of biometry measurement, previous cornea surgery, or co-existing pathology impacting refractive outcomes were excluded. Predicted postoperative spherical equivalents (SE) were calculated with the Barrett Universal II (BU2), Kane, and SRK/T formulas for the implanted intraocular lens (IOL), and complications occurring within 1 year of surgery were abstracted. Sixty eyes of 60 patients met criteria for inclusion, and 40 (66.7%) had postoperative refraction recorded. Absolute prediction errors were 0.49, 0.45, and 0.52D with BU2, Kane, and SRK/T, respectively. Actual postoperative refraction was within 0.5 and 1.0 D of predicted in 26 (65.0%) and 36 (90.0%) using BU2, 23 (58%) and 37 (93%) using Kane, and 21 (52.5%) and 36 (90.0%) using SRK/T. In eyes with macula-on RD, corrected distance visual acuity (CDVA) of logMAR 0.301 (≈20/40) and logMAR 0.544 (≈20/70) or better was achieved in 12 (75.0%) and 15 (93.8%) of eyes. For macula-off RD eyes, these proportions were 19 (63.3%) and 24 (80.0%), respectively. Posterior capsular opacification requiring Nd: YAG capsulotomy was the most frequent complication in 30 (56.7%) eyes. Refractive outcomes of cataract surgery following SB may be modestly reduced, even when using modern formulas. Nevertheless, cataract surgery in this population results in favorable visual outcomes.

Outcomes of Scleral Buckling After Failed Pneumatic Retinopexy.

Purpose: To assess the visual and anatomic outcomes of eyes that had secondary scleral buckle (SB) surgery after unsuccessful pneumatic retinopexy (PR) for rhegmatogenous retinal detachment (RRD). Methods: A retrospective study, performed over a 12-year period, comprised patients who had secondary SB procedures after failed primary PR. Clinical parameters (eg, best-corrected visual acuity [BCVA], lens status, macula status, details of RRD and subretinal fluid) were assessed at presentation, before additional procedures, and at follow-up (6 months, 1 year, and last visit). Statistical comparisons were made using Brown-Forsythe and Welch analysis-of-variance tests, with significance levels set at P < .05. Results: Fifty-four eyes with adequate follow-up were included. Forty-four (81.5%) of 54 eyes had successful retinal reattachment with secondary SB alone. The remaining eyes had subsequent pars plana vitrectomy (PPV). Patients presenting with macula-on RRD who had successful secondary SB had no statistically significant change in BCVA from baseline (mean final, 0.23 ± 0.25 logMAR [Snellen 20/34]; P = .999). There was a statistically significant improvement in BCVA in patients presenting with macula-off RRD who had successful secondary SB (mean final, 0.32 ± 0.36 logMAR [20/42]; P < .001 and mean change, -1.06 ± 0.85 logMAR). Ten patients presenting with macula-off RRD who had failed secondary SB had a significant improvement in the final BCVA (mean final, 0.22 ± 0.28 logMAR [20/33]; P = .044), despite the need for an additional PPV to achieve reattachment. Conclusions: Secondary SB remains a good option for RRD repair after unsuccessful PR and may avoid the need for PPV.
