Risk Factors For Retinal Detachment Research Articles

Risk factors for early and late retinal detachment after boston type I keratoprosthesis surgery.

To determine the differential risk factors for retinal detachment (RD) after Boston Type 1 Keratoprosthesis (B1KPro) during the first year after surgery (early RD; ERD) and afterwards (late RD; LRD). Retrospective cohort study of 94 eyes (90 patients) undergoing B1KPro implantation at Centro de Oftalmología Barraquer from June 2006 to July 2022 with a minimum follow-up of one year. The incidence of RD in the whole sample after B1KPro implantation was 29% (27/94), occurring in 21% of eyes (ERD; 20/94) the first year, and in 7% afterwards (LRD; 7/94). Hypotony was revealed as a significant risk factor for ERD (16/19 = 84%; OR = 14.5, P < 0.0001), together with aphakia (16/20 = 80%; OR = 5.9, P = 0.004), intraocular lens (IOL) removal (4/8 = 50%; OR = 6.2, P = 0.03), previous choroidal detachment (CD; 7/20 = 35%; OR = 35.5, P = 0.001) and previous pars plana vitrectomy (PPV; 15/20 = 75%; OR = 6.6, P = 0.006). Multivariate analysis included hypotony and PPV at any time as variables significantly associated with ERD occurrence. The occurrence of LRD was significantly related to peripheral retinal changes, detected few days before (4/6 = 66%; OR = 65, P < 0.0001). Hypotony emerged as one of the main factors influencing ERD occurrence after B1KPro implantation. Additionally, previous CD, PPV, aphakia, and IOL removal should be considered to estimate the risk of postoperative retinal detachment. In contrast, peripheral retinal changes after B1KPro seem to be significantly related to LRD occurrence. This study reinforces the need for frequent intraocular pressure evaluation, and comprehensive periodic retinal assessment over time. What is known Retinal detachment (RD) is a severe complication after Boston Type 1 Keratoprosthesis (B1KPro) implantation, resulting in a permanent reduction of visual acuity in a clinically relevant percentage of eyes. The time of RD occurrence after B1KPro implantation differs in the literature but is reported to be more common within the first year. Previous aphakia, choroidal detachment, or RD repair, intraocular lens removal, vitritis, or history of Nd-YAG laser have been described as risk factors for RD after B1KPro surgery in samples with varying follow-ups. Multivariate analysis in the first year after B1KPro surgery showed hypotony and pars plana vitrectomy at any time as significant risk factors for early RD. Late RD cases, occurring after one year following the B1KPro surgery, seem to be significantly related to peripheral retinal changes suffered a few days before loss of visual acuity and RD diagnosis. It is plausible to think that risk factors for RD after B1KPro differ in short and long postoperative times.

Risk Factors for Retinal Detachment in Marfan Syndrome After Pediatric Lens Removal

Purpose: To determine Retinal Detachment (RD) risk factors after lens removal surgery in children with Marfan syndrome.Design: Retrospective case control study.Methods:Setting: Institutional case-seriesStudy population: All children (<18 years) with Marfan syndrome that underwent lens removal surgery.Observation procedure: Clinical and surgical characteristics were extracted from children's electronic files: age, Axial Length (AL), gender, number of surgeries received, Intra Ocular Lens (IOL) implantation at the first surgery, complete removal of the capsular bag, final best corrected visual acuity.Main outcome measure: Risk factors associated with RD occurrence.Results: Among 158 eyes included (85 children), 35 eyes (22.2%) developed RD during follow-up. Bilateral detachment occurred in 11 patients (45.8%). Age at the time of the lens removal surgery was not different between groups. Children in the RD group had a higher AL (p<.001), longer follow-up, IOL implantation, and capsular residue. Multivariate analysis identified capsular residue (odds ratio [OR] 16.8; 95% confidence interval [CI], 1.9-148.8; P=0.01), and axial length by (OR 1.3; 95% CI, 1.01-1.7; P=0.03) as predictors for RD.Conclusion: Marfan syndrome children with increased AL were more likely to develop a RD after lens surgery. When considering lens removal surgery in a pediatric population presenting Marfan's syndrome, a complete capsular removal seemed to be the safer option regarding RD risk.

Retinal Detachments after Open-Globe Injury: Risk Factors and Outcomes

To identify risk factors for retinal detachment (RD) after open-globe injury (OGI) and evaluate outcomes of RD repair after OGI. Case-control study. Overall, 769 patients presented with 786 OGIs, which were surgically managed with ≥ 30 days of follow-up. Of the 786 eyes, 223 developed RD, the other 551 served as controls, and RD status of 12 eyes was unknown. A retrospective chart review was performed of all OGIs presented to the University of Michigan between 2000 and 2022. Multivariable regression identified risk factors for RD after OGI and predictors of poor vision after RD repair. Kaplan-Meier analysis estimated time from OGI to RD. Predictors of visual outcome after RD repair after OGI. After OGI, 223 (28.4%) of 786 eyes were diagnosed with RD, with > 73% diagnosed within a month. Predictors of RD include posterior injury (zone II vs. I odds ratio [OR], 1.60 [95% confidence interval {CI}, 1.04-2.46]; P= 0.0331; zone III vs. I OR, 2.29 [1.53-3.41]; P < 0.0001), vitreous hemorrhage (OR, 2.29 [1.54-3.1]; P < 0.0001), and presenting acuity worse than count fingers (CFs) (OR, 2.65 [1.69 - 4.16]; P < 0.0001). Retinal detachment repair took place in 142 of 223 eyes. The mean logarithm of minimal angle of resolution visual acuity (VA) improved from 2.3 ± 0.8 to 1.7 ± 0.9 after RD repair at 6-month follow-up, with 51.2% of eyes achieving CF or better vision. Single surgery anatomic success rate was 69.7% and final anatomic success was 88%. Predictors of vision worse than CF include history of ocular surgery (OR, 0.32 [0.11-0.94]; P= 0.039), proliferative vitreoretinopathy (PVR; OR, 0.39 [0.16 - 0.92]; P= 0.032), aphakia (OR, 0.25 [0.08 - 0.77]; P= 0.016), and redetachment (OR, 0.26 [0.1 - 0.63]; P= 0.003). Most RD occur within the first month after OGI. Patients with posterior injuries, vitreous hemorrhage, or poor presenting VA were more likely to develop RD after OGI. Anatomic success was achieved in the majority, as was final VA of CF vision or better. History of ocular surgery, PVR at time of repair, aphakia, and redetachment were risk factors for a poor outcome.

Incidence and Risk Factors for Retinal Detachment and Retinal Tear after Cataract Surgery: IRIS® Registry (Intelligent Research in Sight) Analysis

To report the incidence of and evaluate demographic, ocular comorbidities, and intraoperative factors for rhegmatogenous retinal detachment (RRD) and retinal tear (RT) after cataract surgery in the American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight). Retrospective cohort study. Patients aged ≥ 40 years who underwent cataract surgery between 2014 and2017. Multivariable logistic regression was used to evaluate demographic, comorbidity, and intraoperative factors associated with RRD and RT after cataract surgery. Incidence and risk factors for RRD or RT within 1 year of cataract surgery. Of the 3 177 195 eyes of 1 983 712 patients included, 6690 (0.21%) developed RRD and 5489 (0.17%) developed RT without RRD within 1 year after cataract surgery. Multivariable logistic regression odds ratios (ORs) showed increased risk of RRD and RT, respectively, among men (OR 3.15; 95% confidence interval [CI], 2.99-3.32; P < 0.001 and 1.79; 95% CI, 1.70-1.89; P < 0.001), and younger ages compared with patients aged > 70, peaking at age 40 to 50 for RRD (8.61; 95% CI, 7.74-9.58; P < 0.001) and age 50 to 60 for RT (2.74; 95% CI, 2.52-2.98; P < 0.001). Increased odds of RRD were observed for procedure eyes with lattice degeneration (LD) (10.53; 95% CI, 9.82-11.28; P < 0.001), hypermature cataract (1.61; 95% CI, 1.06-2.45; P= 0.03), complex cataract surgery (1.52; 95% CI, 1.4-1.66; P < 0.001), posterior vitreous detachment (PVD) (1.24; 95% CI, 1.15-1.34; P < 0.001), and high myopia (1.2; 95% CI, 1.14-1.27; P < 0.001). Lattice degeneration conferred the highest odds of RT (43.86; 95% CI, 41.39-46.49; P < 0.001). In the IRIS Registry, RRD occurs in approximately 1 in 500 cataract surgeries in patients aged > 40 years within 1 year of surgery. The presence of LD conferred the highest odds for RRD and RT after surgery. Additional risk factors for RRD included male gender, younger age, hypermature cataract, PVD, and high myopia. These data may be useful during the informed consent process for cataract surgery and help identify patients at a higher risk of retinal complications.

Swept-Source OCT Mid-Peripheral Retinal Irregularity in Retinal Detachment and Posterior Vitreous Detachment Eyes.

Irregularities in retinal shape have been shown to correlate with axial length, a major risk factor for retinal detachment. To further investigate this association, a comparison was performed of the swept-source optical coherence tomography (SS OCT) peripheral retinal shape of eyes that had either a posterior vitreous detachment (PVD) or vitrectomy for retinal detachment. The objective was to identify a biomarker that can be tested as a predictor for retinal detachment. Eyes with a PVD (N = 88), treated retinal detachment (N = 67), or retinal tear (N = 53) were recruited between July 2020 and January 2022 from hospital retinal clinics in South Australia. The mid-peripheral retina was imaged in four quadrants with SS OCT. The features explored were patient age, eye axial length, and retinal shape irregularity quantified in the frequency domain. A discriminant analysis classifier to identify retinal detachment eyes was trained with two-thirds and tested with one-third of the sample. Retinal detachment eyes had greater irregularity than PVD eyes. A classifier trained using shape features from the superior and temporal retina had a specificity of 84% and a sensitivity of 48%. Models incorporating axial length were less successful, suggesting peripheral retinal irregularity is a better biomarker for retinal detachment than axial length. Mid-peripheral retinal irregularity can identify eyes that have experienced a retinal detachment.

Retinal detachment secondary to bungee jump.

Here, the authors report a case of a 28-year-old myopic male with Left-Eye retinal detachment secondary to a bungee jump. In recent years, a few case reports have archived a variety of visual injuries caused by bungee jumping. But only few literatures have reported the event of retinal detachment related to bungee jumping. Patients with moderate to high myopic refractive error may have different vitreous and retinal changes, like vitreous degeneration, lattice degeneration, and peripheral retinal tears. The authors accept that these retinal findings are more related to the vitreoretinal traction mechanism leading to retinal detachment in bungee jumping. This case highlights that retinal detachment secondary to a bungee jump is a rare but serious ocular manifestation, and bungee jumping should be considered a risk factor for retinal detachment in predisposed patients.

Incidence and Risk Factors for Retinal Detachment Following Cataract Surgery at a Tertiary Center in Jeddah, Saudi Arabia.

Introduction The incidence of retinal detachment in the general population is 0.08%, it has been reported to reach 0.7% or higher following cataract surgery. One of the most important risk factors for retinal detachment is posterior capsular rupture during cataract surgery. Additional risk factors include high myopia, history of ocular trauma, young age, male sex, and diabetes. In this study, we aimed to investigate the incidence and risk factors of retinal detachment following cataract surgery in patients treated at our hospital. Materials and methods This retrospective cohort study was conducted at King Abdulaziz University Hospital (KAUH), a tertiary center in Jeddah, Saudi Arabia. The medical records of 365 patients (365 eyes) who underwent cataract surgery from 2017 to 2021 were reviewed. Results The average age of the 365 patients was 63 years, and 47.7% (n=174) of patients were male. The incidence of retinal detachment was 3.3% (n=12). The risk of RD was 2.8 times higher for the right eye than for the left eye. The incidence of RD was significantly more in eyes with intraoperative posterior capsular rupture, zonular dehiscence, corneal trauma, and surgery combined with anterior vitrectomy than in other eyes. The most common complication of cataract surgery is corneal edema, which was observed in 22.7% of the eyes; our analysis revealed a significant relationship between corneal edema and the duration of surgery. Conclusion In our study, we highlighted the higher incidence of retinal detachment compared to those in other studies; most cases occurred one month postoperatively.

The long and short‐‘sightedness’ of BMP3 in eye development

AbstractPurpose: Following genome‐wide association study for risk factors for retinal detachment, a locus overlapping the BMP3 gene, previously reported to be associated with myopia, was identified and selected for further examination. We prioritized an associated missense plausibly deleterious variant within the BMP3 gene for functional analysis. The BMP signalling pathway has long been implicated in the patterning and development of the eye, but BMP3's role both within this pathway and during eye development and disease is unclear.Methods: The region around the associated missense variant is conserved between human and mouse, and the missense variation was introduced using CRISPR‐cas9 genome editing; loss of function mutations were also produced in the process. Our unit is uniquely equipped to analyse mouse eye phenotypes and using Optical Coherence Tomography (OCT), electroretinogram (ERG) and Optokinetic Drum (OKD) these mice were comprehensively phenotyped through to adulthood. RNA sequencing analysis was also used in cell lines and in primary mouse tissue to further investigate disrupted signalling pathways and potential downstream targets of Bmp3.Results: OCT of mice showed no gross morphological abnormalities in either mice carrying the missense variant or loss of function mutations. ERG and OKD also showed that retinal function and visual acuity was unaltered in either line. However axial length measurements of adult mice showed a significant increase in length of the eye – indicative of myopia. Transcriptional analysis of two different retinal pigmented epithelial cell lines carrying loss of function mutations have been compared to results obtained from whole eye cups of mutant mice, and we have highlighted potential differences and similarities between the two.Conclusions: Future work is required to assess how much the mouse and human cell line results converge, but our mouse results support a role for a BMP pathway in myopia development.

Clinical pattern of retinal detachment at the university of gondar tertiary eye care and training center, north-west ethiopia

Objective: Due to increment in volume of cataract surgery and diabetic retinopathy, the incidence of retinal detachment (RD) is expected to rise in the future. However, little is known about the clinical patterns and risk factor of RD in Ethiopia. This study was aimed to determine the clinical pattern and risk factors of RD at University of Gondar Tertiary eye care and training center (UOG-TECTC). Methods: A hospital based prospective cross sectional study was done involving all consecutive patients with retinal detachment seen over six months period at the UOG-TECTC. Structured questionnaire was used to extract the required data which included demography, ophthalmic history and clinical examination results. Data were entered into SPSS version 20 and analyzed. Results: A total of 73 eyes of 65 patients with RD were analyzed. Two-third of patients were males 42(64.6%) and the median age was 49 years. Rhegmatogenous RD (RRD) was the commonest type of RD found in 58(89.2%) patients. Three quarter of the patients, 49 (75 %), came after 1 month of the symptom occurrence; out of which 20 (41%) visited the center after 1year duration. The commonest identified risk factors were trauma 19(29%) followed by pseudophakia 11(17%). More than three-quarter of the patients 53(81.5%) had detached macula and 60 (92.3%) of the involved eyes were blind at presentation. Conclusion and recommendations: RRD was the commonest type of RD seen in our patients. Majority of the patients visited our center late after macular detachment and trauma was the commonest risk factor. People should be educated to seek health care immediately after the onset of symptoms. Ocular safety precautions should be advised to decrease the risk of ocular trauma. The center should be equipped to manage patients with RD.

Pseudophakic Retinal Detachment: A Narrative Review

Cataract surgery causes changes in intraocular conditions that are a risk factor for retinal detachment. One of the conditions that can occur during cataract surgery is posterior capsule rupture which can increase the risk of pseudophakic retinal detachment (PRD). PRD examination is often obstructed by opacification of the posterior capsule, a reflection of the intraocular lens (IOL), or poor mydriasis. Scleral buckle, pneumatic retinopexy, and primary pars plana vitrectomy, with or without a combination of the scleral buckle, are surgical techniques used in the management of PRD patients. Anatomical and functional postoperative success rates in PRD patients were found to be higher after primary pars plana vitrectomy (PPV) with or without a scleral buckle. This literature review aims to discuss the epidemiology, risk factors, pathogenesis, and management of PRD.

Risk Factors for Retinal Detachment in Acute Retinal Necrosis

Retinal detachment (RD) is associated with poor visual outcomes in patients with acute retinal necrosis (ARN). This research was undertaken to assess the risk factors for RD in ARN. Retrospective cohort study. Patients diagnosed with ARN at a tertiary referral center from 2010 to2020. A chart review was performed for all clinical and surgical encounters. Univariate and multivariate logistic analyses of demographic and clinical variables associated with RD were performed. Survival analyses with Kaplan-Meier estimates were performed to compare the time to RD in herpes simplex virus (HSV)- and varicella zoster virus (VZV)-associated ARN. Demographic information, clinical information (including visual acuity [VA]), intraocular pressure (IOP), intraocular inflammation level, the extent of retinitis, incidence and timing of retinal detachment, date of diagnosis, and treatments performed (including intravitreal injections of antiviral medications). Fifty-four eyes of 47 patients who were diagnosed with ARN were included, with equal proportions of eyes (n= 27; 50%) with VZV-ARN and HSV-ARN. Patients with VZV-ARN were, on average, older, more likely to be men, and more likely to be immunosuppressed compared with patients with HSV-ARN. The clinical characteristics, including the initial VA, initial IOP, anterior segment inflammation, clock hours, and posterior extent of retinitis, were similar between eyes with VZV- and HSV-ARN. In the univariate analysis of clinical and demographic variables associated with the development of RD, initial VA (P= 0.0083) and greater clock hours of retinitis (P= 0.009) were significantly associated with RD. These 2 variables remained significant in the multivariate logistic regression; worse VA at presentation had an odds ratio of 2.34 (95% confidence interval [CI], 1.01-5.44; P= 0.042), and greater clock hours of retinitis had an odds ratio of 1.23 (95% CI, 1.02-1.47; P= 0.025). A Kaplan-Meier survival analysis demonstrated no statistical difference in RD-free survival between HSV- and VZV-ARN. Patients with VZV-ARN were more likely to be older, male, and immunosuppressed compared with those with HSV-ARN, although no clear difference was observed in RD by viral etiology. Poor initial VA and clock hours of retinitis were significantly associated with RD development and may be relevant for patient counseling and prognosis.

POSTOPERATIVE POSTERIOR SEGMENT COMPLICATIONS AFTER BOSTON TYPE 1 KERATOPROSTHESIS: Incidence, Risk Factors, and Intermediate-Term Outcomes.

To identify the incidence of, risk factors for, and outcomes of posterior segment complications (PSC) after Boston Type 1 keratoprosthesis (KPro) implantation. Retrospective, consecutive case series of KPro procedures at the Stein Eye Institute. Data regarding ocular history, intraoperative details, postoperative management, and outcomes were collected. Eyes with at least one PSC (PSC group) were compared with eyes without PSC (No PSC group), and risk factors for PSC were determined. Ninety-five PSC occurred in 69/169 eyes (40.8%), at a mean of 20.1 months after KPro implantation (0.01 complications/eye month). The median follow-up after KPro implantation was 44.0 months (range 3.0-174.4). The most common PSC were epiretinal membrane (16.6%), cystoid macular edema (12.4%), vitritis (11.2%), and retinal detachment (9.5%). Previous retinal detachment repair, concomitant intraocular lens removal, postoperative aphakia, and vitritis were risk factors for retinal detachment. Postoperative infectious keratitis was a risk factor for epiretinal membrane, cystoid macular edema, and vitritis. The posterior segment complication group had a significantly higher rate of eyes failing to maintain visual acuity ≥20/200 (HR = 2.28; 95% CI = 1.35-3.85) and KPro retention failure rate (HR = 1.66; 95% CI = 0.95-2.91). Posterior segment complications occur in approximately 40% of eyes after KPro implantation, resulting in reduced visual outcomes and KPro retention.

Retinal Detachment After Endophthalmitis: Risk Factors and Outcomes.

PurposeTo analyze the risk factors, clinical course, and visual and anatomic outcomes of retinal detachment (RD) after endophthalmitis.Patients and MethodsThis retrospective study included 108 patients diagnosed with endophthalmitis between August 2014 and May 2019 at a single tertiary referral center. Sixteen patients developed RD after endophthalmitis. Retrospective analysis was performed to compare the cohort of endophthalmitis alone versus the cohort that developed RD after endophthalmitis, with analysis of potential risk factors for RD after endophthalmitis and treatment outcomes.ResultsThe incidence of RD after endophthalmitis was 14.8% (N=16/108). The median time to develop RD after endophthalmitis was 27 days (range: 1–581 days, IQR: 25.3). Thirteen (81.3%) cases of RD occurred less than 2 months after the diagnosis of endophthalmitis. The incidence of aphakia (p=0.023) and posterior synechia (PS) (p=0.014) were significantly higher in the RD group. The mean initial and final visual acuity (VA) of the endophthalmitis alone group was 1.9±0.8 logMAR and 1.2±1.0 logMAR (p<0.0001), respectively, and 1.9±0.9 logMAR and 1.3±1.2 logMAR (p=0.07) in the RD group, respectively. Enucleation or evisceration occurred in 31.3% of cases with RD after endophthalmitis. The rate of final retinal re-apposition for the RD cohort was 56.3%.ConclusionThe anatomic and functional outcomes for RD after endophthalmitis remain poor, with significant risk for permanent vision loss. Aphakia and posterior synechiae were seen more often in cases with RD after endophthalmitis.

Nd:YAG capsulotomy is not a risk factor for retinal detachment after phacoemulsification cataract surgery.

To evaluate the cumulative incidence and risk factors of pseudophakic retinal detachment (PRD) following phacoemulsification cataract surgery. Cataract surgeries performed between the years 2007 and 2016 at the Ophthalmology Unit of Kymenlaakso Central Hospital, Kotka, Finland, were included. The cumulative incidence of PRD was estimated throughKaplan-Meier analysis. Patient mortality was incorporated as one of the censoring events. Cox regression analyses were used to evaluate potential risk factors, including age, gender, intraocular lens (IOL) power and previous neodymium-doped yttrium aluminium garnet (Nd:YAG) laser capsulotomy. A total of 17688 eyes of 12003 patients were included. The mean patient age at surgery was 75.2±9.1years with 63.5% females (n=11228). During the mean follow-up time of 4.3±2.7years, 83 laterality-matched PRDs were registered (incidence 0.11% per year). Univariate analyses showed that age (HR 0.93; 95% CI 0.92-0.95), male gender (HR 3.99; 95% CI 2.52-6.33) and IOL power (HR 0.86; 95% CI 0.83-0.90) were significantly associated with PRD (p<0.001 for all) and remained significant in a multivariate analysis. Neither univariate (HR 1.45; 95% CI 0.82-2.54, p=0.201) nor multivariate (HR 1.03; 95%CI 0.57-1.88, p=0.919) analyses showed any association between Nd:YAG capsulotomy and PRD. Male gender, low IOL power and younger age were confirmed as risk factors for PRD after phacoemulsification surgery. Real-world evidence suggests that Nd:YAG capsulotomy does not increase the risk for PRD.

Clinical, radiographic, and intraoperative risk factors for retinal detachment after open globe injury.

Retinal detachment (RD) is a vision-threatening complication of open globe injuries (OGI). This study sought to assess clinical, radiographic, and intraoperative risk factors for RD after OGI. A secondary goal was to test the retinal detachment after open globe injury (RD-OGI) score. Records of patients undergoing OGI repair at a single trauma center over 3years were reviewed using a retrospective case series design. Eyes that were enucleated or lost to follow up within 30days of OGI without evidence of RD were excluded. Potential risk factors for RD development were assessed by logistic regression or chi-square tests were appropriate and were entered into a multivariate logistic regression if significant on univariate analysis. Risk of RD for each eye was categorized by its RD-OGI score. Seventy-three eyes (72 patients) were included. In univariate analysis, afferent pupillary defect, worse visual acuity, posterior injury, vitreous hemorrhage, and posterior segment volume loss (PSVL) on CT were strong predictors of RD. In multivariate analysis, only PSVL on CT (adjusted OR 10.8, P = 0.025) maintained a statistically significant association with RD risk. At 1year, 5% of low-risk eyes, 20% of moderate-risk eyes, and 67% of high-risk eyes developed RD. These rates were not significantly different from the RD-OGI derivation or validation cohorts (P = 0.90 and P = 0.67, respectively). PSVL on CT increases the risk of RD after OGI. The RD-OGI Score was a good prognostic tool for assessing RD risk after OGI in this population.

Incidence and risk factors for retinal detachment following laser-assisted in-situ keratomileusis.

Purpose:The aim of this work was to study the incidence and potential risk factors for development of retinal detachment (RD) after laser-assisted in situ keratomileusis (LASIK) surgery over a long-term follow-up.Methods:This was a retrospective interventional case series. A total of 694 eyes of 352 patients were included who had undergone LASIK surgery at a tertiary eye care institute between January 2005 and September 2015 who had a minimum follow-up of 5 years after the surgery were included. Kaplan–Meier analysis and Cox proportion regression model was used to estimate the potential risk factors and cumulative risk for the development of RD.Results:Out of the total patients, 5 eyes developed RD after a mean follow-up of 7 years. The cumulative risk of RD after 1 year was 0.4%, after 2 years was 0.5% and after 7 years was 0.7%. Increased risk of RD was not associated with age at LASIK surgery, gender, laterality, and spherical equivalent (P > 0.05). A significantly increased risk for the development of RD was observed in eyes that were given prior prophylactic laser photocoagulation for peripheral lesions in multivariate cox proportional regression analysis with a hazard ratio (HR) of 9.33 (CI- 1.554-56.094; P = 0.015).Conclusion:We emphasize the need for a regular follow-up after the LASIK procedure to ensure timely treatment of any new retinal lesions.

Open Globe Injury with Intraocular Foreign Body.

To investigate characteristics of Open Globe Injuries (OGI) that presented with Intra-Ocular Foreign Body (IOFB), along with their long-term visual outcomes, complications and need for subsequent surgeries. Retrospective interventional consecutive case series of OGIs with IOFBs that presented to the Eye Trauma service at the Massachusetts Eye and Ear from 2010 to 2015. Data collected included time from injury to OGI repair, location of injury and IOFB, retinal detachment (RD) rate, presenting and final visual acuity (VA) and subsequent surgeries. Fifty-seven consecutive cases of OGIs with IOFBs were included. The majority of patients were male (93%), mean age was 37 years and mean follow-up was 28 +/- 22 months. The median time from injury to OGI repair was 0 days (range: 0-16 days). Overall, 38/57 (66.7%) eyes achieved final vision of 20/40 or better and 43/57 (75.4%) vision of 20/150 or better. Zone I injuries were the most common (86%), followed by Zone II (16%), and Zone III (10%). 33 cases had IOFBs in the anterior segment only and 24 cases had posterior segment involvement. In total, 30% of cases (17/57) were complicated by an RD, 58.3% (14/24) in the posterior versus 9.1% (3/33) in the anterior IOFB group.( p<0.01). There were no cases of endophthalmitis. Posterior IOFB and higher zone of injury were found to be risk factors for RD both at presentation (all p<0.05) and post-primary repair.(all p<0.05) Posterior IOFB was associated with higher vitrectomy rates both at presentation (p<0.0001) and post-primary repair (p=0.002) and worse long-term visual outcome (p = 0.014). OGIs with IOFB involving the posterior segment are associated with higher complication and re-operation rates and worse visual prognosis compared to those involving the anterior segment only.

Evaluation of vitreous degeneration as a potential risk factor for retinal detachment after phacoemulsification in dogs.

To evaluate vitreous degeneration as a potential risk factor for retinal detachment in dogs after phacoemulsification. Medical records for dogs with preoperative ocular ultrasound and phacoemulsification between September 28, 2006, and August 2, 2016, were reviewed. Ultrasound images were reviewed by two observers independently, and vitreous echogenicity was graded using an established scale. The following factors were compared between eyes with and without retinal detachment: signalment, operated eye, cataract stage at the time of surgery, and presence or absence of the following: lens-induced uveitis (LIU), glaucoma, anterior vitreous presentation, lens subluxation, history of prophylactic retinopexy, diabetes mellitus, operating surgeon, concurrent prophylactic retinopexy, posterior capsular tear, phacoemulsification duration, use of automated anterior vitrectomy, placement of an artificial intraocular lens, and intraocular lens type (polymethyl methacrylate or acrylic foldable). Total follow-up time was recorded. Presence and time from surgery to onset of complications were recorded. Retinal detachment was diagnosed based on observation via indirect ophthalmoscopy or ocular ultrasound. Evaluation for association between vitreous degeneration and retinal detachment included 290 eyes of 180 dogs. There was no statistically significant correlation between vitreous degeneration and postoperative retinal detachment. Retinal detachment was observed in 17 of 290 eyes (5.9%). Vitreous degeneration was marked as present by at least one observer in 189 of 290 eyes (65%). Ultrasonically identifiable vitreous degeneration does not correlate with increased risk of retinal detachment following phacoemulsification.

Akreos AO60 Intraocular Lens Opacification after Retinal Detachment Repair

Abstract We report a case series of 12 eyes that underwent retinal detachment (RD) repair after secondary implantation of Akreos AO60 intraocular lens (IOL) with a subset experiencing the complication of IOL opacification. Major predisposing risk factors for retinal detachment included trauma (42%), prior vitrectomy (33%), and ectopia lentis (17%). Opacification developed in two eyes with gas tamponade and three with silicone oil tamponade. Two eyes required explantation of the IOL. Permanent visually significant Akreos AO60 lens opacification is a possible complication weeks after retinal detachment repair and can occur regardless of tamponade agent.
