Severe Intraocular Inflammation Following Intravitreal Faricimab.

Importance: Monitoring for and reporting potential cases of intraocular inflammation (IOI) in clinical practice despite limited occurrences in clinical trials, including experiences with relatively new intravitreal agents, such as brolucizumab, pegcetacoplan, or faricimab, helps balance potential benefits and risks of these agents. Objective: To provide descriptions of 3 initially culture-negative cases of acute, severe, posterior-segment IOI events occurring within the same month following intravitreal faricimab injections at a single institution. Design, Setting, and Participants: In this case series, 3 patients manifesting acute, severe IOI following intravitreal injection of faricimab were identified between September 20, 2023, and October 20, 2023. Exposure: Faricimab, 6 mg (0.05 mL of 120 mg/mL solution), for neovascular age-related macular degeneration among patients previously treated with aflibercept; 1 patient also had prior exposure to bevacizumab. Main Outcomes and Measures: Visual acuity, vitreous taps for bacterial or fungal cultures, and retinal imaging. Results: All 3 patients received intravitreal faricimab injections between September 20 and October 20, 2023, from 2 different lot numbers (expiration dates, July 2025) at 3 locations of 1 institution among 3 of 19 retina physicians. Visual acuities with correction were 20/63 OS for patient 1, 20/40 OD for patient 2, and 20/20 OS for patient 3 prior to injection. All 3 patients developed acute, severe inflammation involving the anterior and posterior segment within 3 to 4 days after injection, with visual acuities of hand motion OS, counting fingers OD, and hand motion OS, respectively. Two patients were continuing faricimab treatment while 1 patient was initiating faricimab treatment. All received intravitreal ceftazidime, 2.2 mg/0.1 mL, and vancomycin, 1 mg/0.1 mL, immediately following vitreous taps. All vitreous tap culture results were negative. One patient underwent vitrectomy 1 day following presentation. Intraoperative vitreous culture grew 1 colony of Staphylococcus epidermidis, judged a likely contaminant by infectious disease specialists. All symptoms resolved within 1 month; visual acuities with correction were 20/100 OS for patient 1, 20/50 OD for patient 2, and 20/30 OS for patient 3. Conclusions and Relevance: In this case series, 3 patients with acute, severe IOI within 1 month at 3 different locations among 3 ophthalmologists of 1 institution following intravitreal faricimab could represent some unknown storage or handling problem. However, this cluster suggests such inflammatory events may be more common than anticipated from faricimab trial reports, emphasizing the continued need for vigilance to detect and report such cases following regulatory approval.

Ocular, Visual, and Anatomical Outcomes in Eyes Requiring Incisional Intraocular Pressure-Lowering Surgery Following the 0.19-mg Fluocinolone Acetonide Intravitreal Implant.

BACKGROUND AND OBJECTIVE: To assess ocular, visual, and anatomical outcomes following the 0.19-mg fluocinolone acetonide (FAc) intravitreal implant (ILUVIEN®) and incisional intraocular pressure (IOP)-lowering surgery in diabetic macular edema. PATIENTS AND METHODS: From a 36-month, phase 4, open-label, observational study (N = 202 eyes, 159 patients), 8 eyes (7 patients) required IOP-lowering surgery post-FAc; eyes were segregated by FAc-induced (n = 5, 2.47%) versus neovascular glaucoma (NVG)-related (n = 3, 1.49%) IOP elevations and assessed for IOP, best corrected visual acuity (BCVA), central subfield thickness (CST), and cup-to-disc ratio (c/d). RESULTS: Changes at 36 months were +5.4 letters BCVA (P > 0.05) and +0.09 c/d (P = 0.0217); IOP and CST were unchanged. FAc-induced-group eyes required fewer IOP-lowering medications than NVG-group eyes (2.0 versus 4.0; P < 0.01) but for longer duration (15.2 versus 2.6 months; P < 0.001). CONCLUSIONS: Post-FAc IOP-lowering surgery, regardless of cause, largely did not affect the outcomes measured; these procedures, then, may not meaningfully threaten positive outcomes.

Treating patients with geographic atrophy: are we there yet?

Geographic atrophy (GA) is a progressive degenerative disease that significantly contributes to visual impairment in individuals aged 50 years and older. The development of GA is influenced by various modifiable and non-modifiable risk factors, including age, smoking, and specific genetic variants, particularly those related to the complement system regulators. Given the multifactorial and complex nature of GA, several treatment approaches have been explored, such as complement inhibition, gene therapy, and cell therapy. The recent approval by the Food and Drug Administration of pegcetacoplan, a complement C3 inhibitor, marks a significant breakthrough as the first approved treatment for GA. Furthermore, numerous interventions are currently in phase II or III trials, alongside this groundbreaking development. In light of these advancements, this review provides a comprehensive overview of GA, encompassing risk factors, prevalence, genetic associations, and imaging characteristics. Additionally, it delves into the current landscape of GA treatment, emphasizing the latest progress and future considerations. The goal of starting this discussion is to ultimately identify the most suitable candidates for each therapy, highlight the importance of tailoring treatments to individual cases, and continue monitoring the long-term implications of these emerging interventions.

Early Vitrectomy for Endophthalmitis: Are EVS Guidelines Still Valid?

BACKGROUND: Endophthalmitis, a potentially sight-threatening condition, remains a challenge for ophthalmologists worldwide. The endophthalmitis vitrectomy study (EVS) conducted in 1995 compared vitrectomy and intravitreal antibiotic injections to intravitreal antibiotic injections alone for acute post-cataract surgery and secondary intraocular lens endophthalmitis, setting treatment guidelines. However, the landscape of clinical practice has evolved considerably since then, raising questions about the applicability of EVS recommendations today. SUMMARY: Recent studies have proposed that early and complete vitrectomy (CEVE) could potentially be an effective approach for managing endophthalmitis cases, irrespective of the initial visual acuity. However, it is important to note that the level of rigor in these recent studies may not match that of the EVS study, and as such, this assertion should be considered with caution. Furthermore, the EVS study exclusively focused on post-cataract surgery cases, leaving other endophthalmitis types, like post-intravitreal injection and post-traumatic endophthalmitis, without standardized treatment guidelines. Research exploring the role of early vitrectomy in these contexts yields mixed results, emphasizing the need for further investigation and well-designed prospective trials. Endogenous endophthalmitis, originating from systemic infections, adds complexity to the scenario. While early vitrectomy shows promise in specific cases, conflicting evidence necessitates comprehensive research. KEY MESSAGES: This review underscores the necessity for tailored treatment strategies, supporting early vitrectomy when clinically indicated, and advocating for prospective trials to clarify its role in diverse endophthalmitis scenarios. As surgical techniques and antimicrobial therapies continue to advance, reevaluating treatment paradigms becomes crucial to enhance patient outcomes and protect ocular health.

Current Management of Subretinal Hemorrhage in Neovascular Age-Related Macular Degeneration.

Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss among individuals aged 65 years and older in the USA. For individuals diagnosed with AMD, approximately 12% experience varying levels of subretinal hemorrhage (SRH), which can be further classified by size into small, medium, and massive measured in disc diameters. SRH is an acute and rare sight-threatening complication characterized by an accumulation of blood under the retina arising from the choroidal or retinal circulation. Released iron toxins, reduced nutrient supply, fibrin meshwork contraction, and outer retinal shear forces created by SRH contribute to visual loss, macular scarring, and photoreceptor damage. SRH treatment strategies aim to displace hemorrhage from the foveal region and prevent further bleeding. Although there are no standardized treatment protocols for SRH, several surgical and nonsurgical therapeutical approaches may be employed. The most common surgical approaches that have been utilized are pars plana vitrectomy (PPV) combined with multiple maneuvers such as the removal of choroidal neovascularization lesions, macular translocation, retinal pigment epithelium patch repair, SRH drainage, intravitreal injection of recombinant-tissue plasminogen activator (tPA), expansile gas and air displacement, and anti-vascular endothelial growth factor (anti-VEGF) injections. Nonsurgical therapeutical approaches include intravitreal anti-VEGF monotherapy, intravitreal tPA administration without PPV, and photodynamic therapy. This review article aims to explore the current treatment strategies and supporting literature regarding both surgical and nonsurgical, of SRH in patients with AMD. Moreover, this article also aims to highlight the distinct treatment modalities corresponding to different sizes of SRH.

Artificial intelligence in retinal image analysis: Development, advances, and challenges.

Modern advances in diagnostic technologies offer the potential for unprecedented insight into ophthalmic conditions relating to the retina. We discuss the current landscape of artificial intelligence in retina with respect to screening, diagnosis, and monitoring of retinal pathologies such as diabetic retinopathy, diabetic macular edema, central serous chorioretinopathy, and age-related macular degeneration. We review the methods used in these models and evaluate their performance in both research and clinical contexts and discuss potential future directions for investigation, use of multiple imaging modalities in artificial intelligence algorithms, and challenges in the application of artificial intelligence in retinal pathologies.

Surgical Management of Diabetic Macular Edema.

PURPOSE OF REVIEW: Diabetic macular edema (DME) is the accumulation of fluid in the extracellular space within the macula and is a major cause of visual impairment among patients with diabetes. First-line treatment for DME includes pharmacotherapy with intravitreal anti-vascular endothelial growth factor medications and intravitreal corticosteroids. Alternative therapeutic strategies include laser photocoagulation for non-center involving DME, and surgical options such as pars plana vitrectomy (PPV) with or without internal limiting membrane (ILM) peel in cases with vitreoretinal interface anomalies or DME refractory to pharmacotherapy, and the Port Delivery System (PDS) for sustained release of anti-vascular endothelial growth factor (VEGF) medication. Our aim is to review the existing literature on surgical management of DME including imaging changes in chronic DME and the clinical relevance of surgical intervention. RECENT FINDINGS: Imaging changes associated with DME and a worse prognosis include disorganization of the retinal layer, disruption of both the external limiting membrane (ELM) and ellipsoid zone, and vitreomacular interface abnormalities. Studies involving pars plana vitrectomy with and without ILM peel show anatomic improvement but may not always be associated with significant change in visual outcomes. Early studies lacked detailed imaging of the retinal layers and PPV was likely performed as a last resort. In addition, the novel PDS is surgically implanted into the pars plana and works as a drug reservoir with controlled release of drug. However, it has been recalled in patients with wet age-related macular degeneration due to issues with dislodgement. Surgical interventions for DME include pars plana vitrectomy with and without ILM peel and new surgical therapies for DME such as the PDS and subretinal gene therapy have the potential to reduce the risk of DME progression.

Endophthalmitis Following Inadvertent Intraocular Botulinum Toxin A Injection.

Botulinum toxin A injection is a safe alternative procedure to surgery in the management of different types of strabismus. Serious complications such as globe perforation are rare in expert hands. The authors report a case of a child known to have a muscle-eye-brain disease with high myopia who developed endophthalmitis following inadvertent penetrating intraocular botulinum toxin A injection for strabismus correction. To their knowledge, this serious complication after penetrating botulinum toxin A injection has not been previously reported. [J Pediatr Ophthalmol Strabismus. 2023;60(2):e8-e10.].

International Validation of Myopic Traction Maculopathy Staging System.

BACKGROUND AND OBJECTIVE: The aim of this study was to evaluate the interobserver agreement of the myopic traction maculopathy (MTM) staging system (MSS). PATIENTS AND METHODS: Each observer was asked to look at the MSS Table and then identify, in each optical coherence tomography scan, one among four stages of MTM in the retina, one among three stages in the fovea, and, as secondary findings, the presence or absence of an outer lamellar macular hole and the presence or absence of epiretinal abnormalities. The interobserver agreement value was calculated using the Gwet's AC1 unweighted and AC2 weighted statistics. The outcomes were interpreted as poor (<0.00), slight (0.00 to 0.20), fair (0.21 to 0.40), moderate (0.41 to 0.60), substantial (0.61 to 0.80), or almost perfect (0.81 to 1.00) agreement. RESULTS: The agreement, among 65 participants, was 0.62 (AC1) and 0.77 (AC2) for the retina stage; 0.63 (AC1) and 0.81 (AC2) for the fovea stage; 0.56 (AC1) for the outer lamellar macular hole; and 0.26 (AC1) for epiretinal abnormalities. CONCLUSION: The MSS is highly reproducible and helps ophthalmologists to share information on MTM in a more accurate and reliable way. [Ophthalmic Surg Lasers Imaging Retina 2023;54(3):153-157.].

DIRECT MACULAR HOLE MANIPULATION RESULTS IN HIGH SUCCESS RATE IN SECONDARY MACULAR HOLE REPAIR.

PURPOSE: To investigate closure rates and functional outcomes of surgery for refractory and recurrent macular holes (MHs) in a real-world setting. METHODS: Retrospective review of secondary MH surgeries. RESULTS: A total of 72 eyes from 72 patients were included. Eyes had a mean of 1.51 surgeries before inclusion into this study with a mean MH size of 762 µ m and a mean baseline logarithm of the minimum angle of resolution best-corrected visual acuity of 1.11 (∼20/260 Snellen). Closure rates were 89.3% for tissue transplantation, 77.3% for internal limiting membrane (ILM) flaps, 92.9% for MH manipulation, and 12.5% for repeat ILM peeling ( P < 0.05). Best-corrected visual acuity changes in logarithm of the minimum angle of resolution from baseline to postoperative month six were +0.29 for ILM peeling alone (15 Early Treatment Diabetic Retinopathy Study letters worse), -0.39 for MH manipulation (20 Early Treatment Diabetic Retinopathy Study letters improved), -0.23 for tissue transplantation (13 Early Treatment Diabetic Retinopathy Study letters improved), and -0.2 for ILM flaps (10 Early Treatment Diabetic Retinopathy Study letters improved; P < 0.05). CONCLUSION: Secondary MH closure is possible using various surgical techniques with acceptable anatomical closure rates. Repeat ILM peeling is associated with the lowest closure rates and poorest functional results. To distinguish between techniques would require a large sample size of approximately 750 eyes.

Surgery for Infectious Retinitis - When Medical Therapy Is Not Sufficient: The Moacyr E. Alvaro Pan-American Lecture 2023.

BACKGROUND: Viral retinitis composes a group of infectious ocular diseases with poor prognoses. With the advent of antivirals and HAART, the treatment of these diseases has evolved and ocular outcomes have improved. However, even with prompt medical treatment, a significant number of patients will experience complications that require surgical intervention. While there has been an abundance of research examining the medical treatment of CMV retinitis and acute retinal necrosis, the research examining surgical outcomes of complications such as retinitis-associated retinal detachment is comparatively limited. METHODS: Literature review. RESULTS: In this review, we discuss the current literature examining treatment of CMV retinitis and acute retinal necrosis, with a focus on surgical management of complications such as retinal detachment. CONCLUSIONS: Despite significant improvements in the medical treatment of CMV retinitis and ARN over the last three decades, vision-threatening complications such as retinal detachment are relatively common and require surgical management via PPV, laser photocoagulation, and intraocular gas or silicone oil tamponade.

Pneumatic Retinopexy Versus Pars Plana Vitrectomy for the Management of Retinal Detachment: A Systematic Review and Meta-Analysis.

INTRODUCTION: Pneumatic retinopexy (PnR) was proposed as an alternative to pars plana vitrectomy (PPV) in certain circumstances. PnR is an outpatient procedure and more cost-effective. However, its benefits should be judged alongside its success rate and adverse events. Herein, we compare the efficacy and safety of PnR and PPV for rhegmatogenous retinal detachment (RRD) repair. METHODS: We searched the PubMed, Scopus, EMBASE, Web of Science, Cochrane, and Google Scholar databases. Observational and interventional studies comparing the efficacy and safety of PnR and PPV were included. The outcomes were the success rate of the treatment, improvement in visual acuity, and adverse event rates. Subgroup analysis was performed based on the lens and macula status. Eleven articles were eligible to enter our study; these consisted of 11,346 patients with a mean age of 74.1. RESULTS: PnR was superior to PPV in terms of retinal displacement, photoreceptor integrity, visual function, and vertical metamorphopsia scores. In the meta-analysis, PPV showed higher a reattachment rate than PnR (OR = 3.39, 95% CI 2.25-5.11). Subgroup analysis showed that the advantage of PPV over PnR was more pronounced in studies with fewer phakic eyes, more macula-on patients, and in cases with primary PnR failure. While PnR patients had better pre-op (SMD = - 0.58, 95% CI = - 1.16 to 0.00) and post-op (SMD = - 0.45, 95% CI = - 0.60 to - 0.30) LogMAR, the improvement in visual acuity after surgery was higher in PPV patients (SMD = 0.49, 95% CI = - 0.15 to 1.13). CONCLUSION: The success rate of PnR was higher in studies published after 2015 compared to previous studies (82% vs. 59%). Cataract formation and surgery were significantly higher in the PPV arm, while the occurrence of new retinal tears was more frequent in the PnR group. PnR can be used as the primary procedure for RRD repair in selected cases. However, we propose some modifications to the PIVOT criteria, e.g., the exclusion of cases presenting with several risk factors of poor outcomes.

Combined Therapeutic Penetrating Keratoplasty and Pars Plana Vitrectomy for the Treatment of Infectious Keratitis Endophthalmitis: Mexican Endophthalmitis Study Group Protocol 4.

PURPOSE: The purpose of this study was to assess the role of combined surgical treatment of therapeutic penetrating keratoplasty and pars plana vitrectomy in the anatomical and functional outcome of infectious keratitis endophthalmitis. METHODS: This study reviewed the medical records of 4 participating centers in the United States and Mexico. This study included patients with a clinical diagnosis of infectious keratitis endophthalmitis who had been treated with an early therapeutic penetrating keratoplasty and pars plana vitrectomy as the main treatment for endophthalmitis. From each medical record, the study retrieved demographic data, relevant medical and drug history, baseline clinical manifestation of endophthalmitis, best-corrected visual acuity, and the need for enucleation/evisceration for the control of the infection or any other reason through the follow-up. RESULTS: The study included 48 patients (50.15 ± 20.6 years). The mean follow-up time was 13 ± 0.5 months. The mean best-corrected visual acuity at baseline was 2.1 ± 0.25 logarithm of the minimum angle of resolution. At month 12 was 2.09 ± 0.61 logarithm of the minimum angle of resolution ( P = 0.9). The overall prevalence of enucleation/evisceration was 8.3% (95% confidence interval: 2.32%-19.98%). The prevalence of a vision of no-light perception was 20.8% (95% confidence interval: 2.32%-19.98%). CONCLUSIONS: Combined surgery for severe cases of infectious keratitis endophthalmitis eradicates the infection in most cases, while significantly improving the overall outcomes.

Pseudo second anterior lens capsule during post-vitrectomy cataract surgery: A case report.

Purpose: To report the unexpected finding of a membrane resembling a second anterior lens capsule during cataract surgery after previous pars plana vitrectomy (PPV) with silicone oil tamponade for retinal detachment. Observations: A 26-year-old male with a history of two retinal detachment repairs of the right eye over a 5-month period, presented with decreased vision. The first retinal detachment repair was performed with a 23-gauge PPV and the second with a 25-gauge PPV, scleral buckle and placement of silicone oil. Additional ocular history includes bilateral megalocornea, high myopia, and temporal lens coloboma. Upon presentation, slit lamp exam showed migration of silicone oil to the anterior chamber and a nuclear cataract. A decision was made to perform combined silicone oil removal and cataract extraction with intraocular lens (IOL) implant of the right eye. After capsulorrhexis, hydrodissection of the lens was not completed successfully since the presence of a membrane was detected. This membrane was cut, achieving partial completion of the second capsulorrhexis, which was further advanced using a forceps following the contour of the first capsulorrhexis. The cataract was removed without further difficulty and the IOL was placed into the capsular bag with good centration. The membrane was submitted to pathology, and upon microscopic examination was found to represent fibrocellular tissue with some cells expressing PAX8 and cytokeratin AE1/AE3. Conclusions and importance: This case reports the unusual finding of a membrane that behaved as a second anterior lens capsule intraoperatively and that expressed novel pathology markers. These findings may better prepare ophthalmologists for similar pathologies they may encounter during capsulorrhexis.

Visual acuity after cataract surgery in Macular Telangiectasia Type 2 Stage 3 to 5.

BACKGROUND: The purpose of this study was to evaluate visual acuity after cataract surgery in eyes with Macular Telangiectasia (MacTel) Type 2. METHODS: Single-center retrospective cohort study of patients with MacTel Type 2 who underwent cataract surgery and were managed at the same institution. Patients underwent pre-operative assessment by a retinal specialist with examination and optical coherence tomography (OCT) at the same institution. The main outcome measure was the post-operative change in best corrected visual acuity (BCVA). Secondary study outcomes were achieving post-operative BCVA better than Snellen acuity of 20/40 and time to BCVA loss by two lines or more (10 or more ETDRS letters). RESULTS: A total of 20 eyes (11 patients) underwent cataract surgery and were followed for a median of 25.5 months (IQR 17.5-44.2 months). The median post-operative BCVA improvement was 10.5 letters (IQR 3.50-20.25). Nuclear sclerosis severity [ß = 8.99 (95% CI 3.35, 14.6), p = 0.00177] was associated with post-operative change in BCVA and central foveal ellipsoid zone (EZ) breaks [OR 1.33 × 10-9 (95% CI 5.12 × 10-10-3.43 × 10-9), p < 0.001] on OCT was inversely correlated with post-operative BCVA > 20/40 using a multivariate generalized linear model. Central foveal EZ breaks [HR 1.77 × 109 (95% CI 3.86 × 108, 8.11 × 109), p < 0.001] and MacTel Type 2 disease stage [HR 2.83, (95% CI 1.12, 7.12), p = 0.027] were independently associated with shorter time to vision loss of two lines or more in a multivariate Cox regression model. CONCLUSIONS: Visual acuity significant improved after cataract surgery in eyes with MacTel Type 2 regardless of disease severity. The presence of central foveal EZ breaks may predict poorer post-operative visual acuity and subsequent vision loss from disease progression.

Choroidal Macrovessel Diagnosed on Multimodal Imaging, including Swept-Source Optical Coherence Tomography Angiography.

Choroidal macrovessel (CM) is a rare anomalous vascular lesion in the choroid. In this case report, we describe a 72-year-old Caucasian man diagnosed with an incidental heavily branching CM in the macula of his right eye based on multimodal imaging, including enhanced depth imaging optical coherence tomography (OCT), swept-source OCT angiography, and indocyanine green angiography. Multimodal imaging is valuable in demonstrating the distinctive appearance of this entity and differentiating it from more vision-threatening differential diagnoses, such as ophthalmomyiasis interna, choroidal neoplasms, retinochoroidal anastomosis, and inflammatory conditions.

SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY BIOMARKERS OF RETINAL HYPERPERMEABILITY AND CHOROIDAL INFLAMMATION AS PREDICTORS OF SHORT-TERM FUNCTIONAL AND ANATOMICAL OUTCOMES IN EYES WITH DIABETIC MACULAR EDEMA TREATED WITH INTRAVITREAL BEVACIZUMAB.

PURPOSE: To assess spectral domain optical coherence tomography biomarkers of short-term outcomes in eyes with diabetic macular edema treated with intravitreal bevacizumab. METHODS: In a prospective interventional case series, 66 eyes with diabetic macular edema underwent 3 monthly intravitreal bevacizumab injections. Best-corrected visual acuity measurement and spectral domain optical coherence tomography were performed at baseline and at 3 months. Multivariate regression analysis was performed to investigate the baseline spectral domain optical coherence tomography parameters as predictors of functional and anatomical outcomes. RESULTS: Patients with diabetic nephropathy had greater subfoveal choroidal thickness (300.8 ± 35.54 vs. 253.0 ± 50.07 µm, P < 0.01) and were more likely to have subretinal fluid (r = 0.26, P = 0.03) at baseline. Multivariate analysis showed that the extent of external limiting membrane disruption (P = 0.03) and the extent of disorganization of retinal inner layers (P = 0.03) at baseline were predictors of best-corrected visual acuity at 3 months, whereas the extent of disorganization of retinal inner layers (P = 0.04) and duration of diabetes mellitus (P = 0.03) were predictors of central subfield thickness at 3 months. CONCLUSION: External limiting membrane disruption and disorganization of retinal inner layers, as the spectral domain optical coherence tomography biomarkers of retinal hyperpermeability, can predict short-term outcomes in diabetic macular edema eyes treated with intravitreal bevacizumab.

Vitrectomy versus Vitrectomy with Scleral Buckling in the Treatment of Giant Retinal Tear Related Retinal Detachments: An International Multicenter Study.

PURPOSE: To determine the practice pattern for treating giant retinal tear (GRT) related detachments, and their anatomic and visual outcomes with pars plana vitrectomy (PPV) with or without scleral buckling (SB). DESIGN: Retrospective cohort study. SUBJECTS: Eyes with GRT detachments repaired from 2008 to 2020 with at least 6 months of follow-up from 7 institutions in North and South America, Europe, and Asia. METHODS: Eyes repaired using PPV versus PPV/SB were compared. MAIN OUTCOME MEASURES: Anatomic and functional outcomes. RESULTS: A comparable number of eyes underwent PPV (n = 101) and PPV/SB (n = 99). Except for history of developmental abnormalities, prior intraocular surgery, and lens status, no differences in baseline demographics, ocular characteristics, or intraoperative surgical adjuncts were observed. The overall single surgery anatomic success (SSAS) at 6 months and 1 year were similar between the groups (82.2% and 77.2% of PPV, and 87.9% and 85.7% of PPV/SB). When stratified by age, the 1-year SSAS rate was higher for PPV/SB (88.5%) than PPV (56.3%) (P = 0.03) for children <18 years. For both children and adults, the mean best-corrected visual acuity (BCVA) at baseline did not differ between the PPV and PPV/SB groups. However, for children, mean BCVA at 1 year was better in the PPV/SB than PPV groups (P = 0.001) while for adults, no difference was found between the 2 groups. The mean time to the first redetachment was 7.9 months in the PPV group and 5.5 months in the PPV/SB group (P = 0.8). Proliferative vitreoretinopathy was the most common cause for redetachment (70.4% of PPV and 93.8% of PPV/SB in redetached eyes; P = 0.1). Postoperative complications were also similar between the 2 groups, including ocular hypertension, epiretinal membrane, and cataract formation. CONCLUSIONS: PPV and PPV/SB are equally popular among surgeons globally for managing GRT detachments and have comparable anatomic and visual outcomes in adults. In children, PPV/SB is superior to PPV for anatomic and functional success at 1 year. In adults, the relief of traction by the GRT may reduce peripheral traction and obviate the need for an SB. However, in children, a supplemental SB can be beneficial as complete vitreous shaving and posterior hyaloid detachment, and postoperative positioning, are difficult in this group.

Clinical characteristics of full thickness macular holes that closed without surgery.

PURPOSE: To ascertain the anatomic factors that help achieve non-surgical sealing in full thickness macular hole (FTMH). METHODS: Retrospective collaborative study of FTMH that closed without surgical intervention. RESULTS: A total of 78 patients (mean age 57.9 years) included 18 patients with blunt ocular trauma, 18 patients that received topical or intravitreal therapies and 42 patients with idiopathic FTMH. Mean±SD of the initial corrected visual acuity (VA) in logMAR improved from 0.65±0.54 to 0.34±0.45 (p<0.001) at a mean follow-up of 33.8±37.1 months. FTMH reopened in seven eyes (9.0%) after a mean of 8.6 months. Vitreomacular traction was noted in 12 eyes (15.8%), perifoveal posterior vitreous detachment in 42 (53.8%), foveal epiretinal membrane in 10 (12.8%), cystoid macular oedema (CME) in 49 (62.8%) and subretinal fluid (SRF) in 20 (25.6%). By multivariate analysis, initial VA correlated to the height (p<0.001) and narrowest diameter of the hole (p<0.001) while final VA correlated to the basal diameter (p<0.001). Time for closure of FTMH (median 2.8 months) correlated to the narrowest diameter (p<0.001) and the presence of SRF (p=0.001). Mean time for closure (in months) was 1.6 for eyes with trauma, 4.3 for eyes without trauma but with therapy for CME, 4.4 for eyes without trauma and without therapy in less than 200 µm in size and 24.7 for more than 200 µm. CONCLUSION: Our data suggest an observation period in new onset FTMH for non-surgical closure, in the setting of trauma, treatment of CME and size <200 µm.

Repair of progressive retinal detachment complicating degenerative retinoschisis: surgical management and outcomes in phakic eyes.

BACKGROUND: Degenerative retinoschisis is a common condition defined by the splitting of the neurosensory retina that may rarely be associated with progressive retinal detachment (RD). Here, we aim to describe the anatomic and functional outcomes of surgical treatment of progressive symptomatic retinal detachment complicating degenerative retinoschisis (PSRDCR) using pars plana vitrectomy (PPV), scleral buckle (SB), or combined PPV/SB procedure. METHODS: A retrospective chart review of patients with PSRDCR between Jan 1, 2008 and Dec 31, 2019 was conducted. Data regarding demographics, surgical approach, and anatomic/functional outcomes were collected. RESULTS: Of the 4973 charts with RD repair during the study period, 36 eyes (0.7%) had retinoschisis with RD. 18 eyes met inclusion criteria (0.4%). The median age was 54 years (range 18-74) and all eyes were phakic. All eyes had outer layer breaks (OLBs) and 16 eyes (89%) had identifiable inner layer breaks. All OLBs were posterior to the equator in charts where position was recorded (16 eyes). The single surgery anatomic success (SSAS) and final anatomical success rates were 66% (12/18) and 100%, respectively. Eyes treated with PPV/SB had an SSAS rate of 75% (9/12), while PPV and SB had SSAS rates of 66% (2/3) and 33% (1/3), respectively. CONCLUSIONS: PSRDCR is an exceedingly rare complication of degenerative retinoschisis associated with an SSAS rate lower than for uncomplicated rhegmatogenous RD. The majority of PSRDCR were repaired via combined PPV/SB in our study, and the rarity of this complication limits statistical support of an optimal surgical method in our and prior studies. The role of SB combined with PPV for PSRDCR requires further investigation.
