RESUMO

PURPOSE: Long-acting injectable steroids are changing the treatment paradigm for patients with chronic intraocular inflammation and cystoid macular edema (CME). We report the use of the fluocinolone implant 0.18 mg in patients with chronic postsurgical CME after pars plana vitrectomy. METHODS: This is a retrospective case series of 24 vitrectomized eyes which received fluocinolone implant for the management postsurgical CME. Clinical outcomes and requirement for rescue therapy were studied. RESULTS: Median length of follow-up was 19.3 months (range 8.3-23.2 months). There was an improvement in median central subfield thickness from 412 µ m (range 167-806 µ m) to 311 µ m (range 157-686 µ m) after fluocinolone implant ( P < 0.001). The injection burden decreased significantly after study treatment ( P < 0.001); however, there was no significant change in visual acuity ( P = 0.334). Eighteen eyes had control of CME that did not require additional intravitreal therapy. Four eyes had initially controlled but recurrent CME requiring intravitreal steroid therapy at median of 7.8 months (range 7.6-15.4 months). One eye never attained sufficient inflammatory control despite rescue therapy. CONCLUSION: Fluocinolone implant can be an effective treatment in vitrectomized patients with chronic postsurgical CME and can help decrease the overall injection burden.

RESUMO

PURPOSE: To describe the clinical outcomes and surgical technique in transconjunctival sutureless intrascleral fixation of intraocular lenses, including the effectiveness of haptic flanging and peripheral iridotomy. METHOD: Retrospective series of patients who underwent sutureless intrascleral fixation of three-piece intraocular lenses by a single surgeon. RESULTS: A total of 488 eyes were included in this study. Mean follow-up was 444 days. Mean preoperative best-corrected visual acuity was 20/355, and mean postoperative best-corrected visual acuity was 20/39 (P < 0.001). Intraocular lens dislocation occurred during the postoperative period in 67 (13.7%), with the majority (65.7%) occurring within 3 months after surgery. Dislocation occurred in 13 of 196 (6.6%) flanged haptics versus 54 of 292 (18.5%) unflanged haptics (P < 0.001). Reverse pupillary block occurred in 7 of 231 eyes (3.0%) without intraoperative peripheral iridotomy but only in 1 of 257 eyes (0.4%) with iridotomy (P = 0.0297). Other complications included haptic exposure (1.2%), retinal detachment (1.0%), and endophthalmitis (0.4%). CONCLUSION: This is the largest reported series of sutureless intrascleral fixation of intraocular lenses using trocar cannulas. This technique is an effective surgical option with low complication rates. The authors recommend that haptic flanging and peripheral iridotomy be performed in all cases.

RESUMO

PURPOSE: To evaluate the refractive outcomes of sutureless intrascleral fixation of intraocular lens with pars plana vitrectomy. METHOD: A retrospective, consecutive cohort from multiple surgeons of a single center. Primary outcomes included spherical equivalent (SEQ) and change in SEQ (ΔSEQ) from preoperative intraocular lens power calculations. Secondary outcomes included refractive outcomes of fixation at 1.5 mm, 2 mm, and 2.5 mm posterior to the limbus. RESULTS: In total, 84 eyes of 80 patients were included. Preoperative logarithm of the minimum angle of resolution visual acuity was 1.21 ± 0.68 (20/320). The mean follow-up time was 2.33 ± 1.36 years. At 3 months, SEQ was -0.50 ± 1.59 D and ΔSEQ was 0.58 ± 1.49 D. At 1 year, SEQ was -0.55 ± 1.32 D and ΔSEQ was 0.39 ± 1.42 D. At the last follow-up, logarithm of the minimum angle of resolution visual acuity was 0.34 ± 0.34 (20/40), SEQ was -0.51 ± 1.44 D, and ΔSEQ was 0.57 ± 1.27 D. There was no difference between SEQ or ΔSEQ throughout follow-up (P = 0.97 and P = 0.96, respectively). At fixation distances more posterior to the limbus, mean ΔSEQ was more hyperopic at 3 months, 1-year, and the last follow-up (P = 0.02, P = 0.01, and P = 0.006, respectively). CONCLUSION: Refractive outcomes for sutureless intrascleral fixation of intraocular lens with pars plana vitrectomy were favorable and showed stability postoperatively. These results may aid surgeons achieve better desired refractive outcomes for this technique.

RESUMO

PURPOSE: To evaluate the preoperative features, intraoperative management, and postoperative outcomes of recurrent macular holes that developed after initial successful repair with small-gauge vitrectomy techniques. METHODS: We retrospectively reviewed 392 eyes with idiopathic macular holes successfully treated with small-gauge vitrectomy. Thirteen of these eyes underwent reoperation after macular hole reopening. We assessed patient demographics, visual acuity, postoperative anatomical success, potential precipitating clinical factors of hole reopening, and details of the surgical repairs of these eyes. RESULTS: Macular hole reopening occurred in 13 (3.3%) of 392 eyes in a mean of 28 months (range, 1-120 months) after initial repair. All 13 recurrent holes closed after a second vitrectomy, but 4 (31%) holes reopened again and had vitrectomy. Of these, 2 reopened a third time. Ultimately, 11 (85%) holes were closed at the most recent follow-up. The mean best-corrected visual acuity was 20/81 before initial repair, 20/148 after the first reopening, 20/115 after repair of the first reopening, and 20/55 after repair of >1 reopening. Ten of 13 (77%) patients had, or later developed, macular holes in the other eye during follow-up. CONCLUSION: Reoperation successfully achieved hole closure and ultimate visual improvement in most eyes with recurrent macular holes. Most patients with recurrent holes previously had, or later developed, full-thickness macular holes in the other eye.

RESUMO

PURPOSE: To determine if (1) tortuosity assessment by a computer program (ROPtool, developed at the University of North Carolina, Chapel Hill, and Duke University, and licensed by FocusROP) that traces retinal blood vessels and (2) assessment by a lay reader are comparable with assessment by a panel of 3 retinopathy of prematurity (ROP) experts for remote clinical grading of vascular abnormalities such as plus disease. DESIGN: Validity and reliability analysis of diagnostic tools. PARTICIPANTS: Three hundred thirty-five fundus images of prematurely born infants. METHODS: Three hundred thirty-five fundus images of prematurely born infants were obtained by neonatal intensive care unit nurses. A panel of 3 ROP experts graded 84 images showing vascular dilatation, tortuosity, or both and 251 images showing no evidence of vascular abnormalities. These images were sent electronically to an experienced lay reader who independently graded them for vascular abnormalities. The images also were analyzed using the ROPtool, which assigns a numerical value to the level of vascular abnormality and tortuosity present in each of 4 quadrants or sectors. The ROPtool measurements of vascular abnormalities were graded and compared with expert panel grades with a receiver operating characteristic (ROC) curve. Grades between human readers were cross-tabulated. The area under the ROC curve was calculated for the ROPtool, and sensitivity and specificity were computed for the lay reader. MAIN OUTCOME MEASURES: Measurements of vascular abnormalities by ROPtool and grading of vascular abnormalities by 3 ROP experts and 1 experienced lay reader. RESULTS: The ROC curve for ROPtool's tortuosity assessment had an area under the ROC curve of 0.917. Using a threshold value of 4.97 for the second most tortuous quadrant, ROPtool's sensitivity was 91% and its specificity was 82%. Lay reader sensitivity and specificity were 99% and 73%, respectively, and had high reliability (κ, 0.87) in repeated measurements. CONCLUSIONS: ROPtool had very good accuracy for detection of vascular abnormalities suggestive of plus disease when compared with expert physician graders. The lay reader's results showed excellent sensitivity and good specificity when compared with those of the expert graders. These options for remote reading of images to detect vascular abnormalities deserve consideration in the quest to use telemedicine with remote reading for efficient delivery of high-quality care and to detect infants requiring bedside examination.

RESUMO

PURPOSE: To determine the feasibility and safety of bilateral simultaneous vitreoretinal surgery in pediatric patients. DESIGN: International, multicenter, interventional, retrospective case series. PARTICIPANTS: Patients 17 years of age or younger from 24 centers worldwide who underwent immediate sequential bilateral vitreoretinal surgery (ISBVS)-defined as vitrectomy, scleral buckle, or lensectomy using the vitreous cutter-performed in both eyes sequentially during the same anesthesia session. METHODS: Clinical history, surgical details and indications, time under anesthesia, and intraoperative and postoperative ophthalmic and systemic adverse events were reviewed. MAIN OUTCOME MEASURES: Ocular and systemic adverse events. RESULTS: A total of 344 surgeries from 172 ISBVS procedures in 167 patients were included in the study. The mean age of the cohort was 1.3±2.6 years. Nonexclusive indications for ISBVS were rapidly progressive disease (74.6%), systemic morbidity placing the child at high anesthesia risk (76.0%), and residence remote from surgery location (30.2%). The most common diagnoses were retinopathy of prematurity (ROP; 72.7% [P < 0.01]; stage 3, 4.8%; stage 4A, 44.4%; stage 4B, 22.4%; stage 5, 26.4%), familial exudative vitreoretinopathy (7.0%), abusive head trauma (4.1%), persistent fetal vasculature (3.5%), congenital cataract (1.7%), posterior capsular opacification (1.7%), rhegmatogenous retinal detachment (1.7%), congenital X-linked retinoschisis (1.2%), Norrie disease (2.3%), and viral retinitis (1.2%). Mean surgical time was 143±59 minutes for both eyes. Higher ROP stage correlated with longer surgical time (P = 0.02). There were no reported intraoperative ocular complications. During the immediate postoperative period, 2 eyes from different patients demonstrated unilateral vitreous hemorrhage (0.6%). No cases of endophthalmitis, choroidal hemorrhage, or hypotony occurred. Mean total anesthesia time was 203±87 minutes. There were no cases of anesthesia-related death, malignant hyperthermia, anaphylaxis, or cardiac event. There was 1 case of reintubation (0.6%) and 1 case of prolonged oxygen desaturation (0.6%). Mean follow-up after surgery was 103 weeks, and anatomic success and globe salvage rates were 89.8% and 98.0%, respectively. CONCLUSIONS: This study found ISBVS to be a feasible and safe treatment paradigm for pediatric patients with bilateral vitreoretinal pathologic features when repeated general anesthesia is undesirable or impractical.

RESUMO

PURPOSE OF REVIEW: To review the different techniques for management of dislocated intraocular lenses in eyes with insufficient capsular support with a focus on recent studies and techniques reported in the literature. RECENT FINDINGS: Visual outcomes generally improve regardless of intraocular lens selection and surgical techniques. New techniques include sutureless scleral fixation with the use of posterior segment tools and use of hybrid instrumentation for 25-/27-gauge vitrectomy. SUMMARY: IOL selection and surgical technique should be tailored to each patient based on the preexisting disorder that led to the dislocation. The decision ultimately depends on surgeon comfort and experience with the procedure, and the presenting pathology.

RESUMO

PURPOSE: Widefield photography and angiography provide access up to 200-degrees of the retinal periphery. The range of normal peripheral findings has not been characterized, yet is relevant to studies addressing putative peripheral retinal vascular pathology. METHODS: This study was an observational retrospective cohort study. Adult patients with epiretinal membrane or choroidal nevi who underwent imaging with Optos 200 MA/200Tx were included. Dye transit times, peripheral arteriovenous shunting, presence of vessels crossing the horizontal raphe, right angle vessels, terminal networks, absence of capillary detail, ground glass hyperfluorescence, peripheral drusen, and microaneurysms were evaluated. RESULTS: Fifty-eight eyes of 31 patients met inclusion criteria. Mean peripheral arterial filling time was 8.65 ± 2.54 seconds (range 3-15 seconds). One or more peripheral anomalies were noted in all patients (P < 0.01). The prevalences of findings were: arteriovenous shunting (0.00%), vessels crossing the horizontal raphe (44.83%), right angle vessels (70.69%), terminal networks (77.59%), absence of capillary detail (98.28%), ground glass hyperfluorescence (87.93%), drusen (34.48%), and microaneurysms (41.38%). CONCLUSION: There was a high prevalence of peripheral vascular anatomic variations in eyes expected to have normal peripheral retinal vasculature. These findings may provide a reference for future studies addressing putative pathologic peripheral angiographic findings.

RESUMO

PURPOSE: We sought to assess the clinical outcomes and complications of two approaches to scleral fixation of intraocular lenses (IOLs): transconjunctival fixation through trocar cannulas and fixation using scleral tunnels created with a microvitreoretinal (MVR) blade. METHODS: This retrospective chart review was comprised of 23 eyes that received scleral fixation of a three-piece IOL with concurrent pars plana vitrectomy between June 2012 and June 2014. Scleral fixation was performed either by transconjunctival fixation through trocar cannulas (cannula fixation) or by the creation of scleral tunnels using an MVR blade (tunnel fixation). The preoperative and postoperative corrected distance visual acuities (CDVA), spherical equivalents (SE), and complications were evaluated. RESULTS: 15 cannula fixations and 8 tunnel fixations were performed. Mean follow-up was 353 days (Range: 94 - 790 days). Fifteen IOLs were fixated 2 mm posterior to the limbus. Seven IOLs were fixated 1.5 mm posterior to the limbus, and one IOL was fixated 0.75 mm posterior to the limbus. Mean preoperative CDVA was logMAR 1.17 (Snellen 20/297), and mean postoperative CDVA was logMAR 0.37 (Snellen 20/47) (p <0.0001). At last follow-up, none of the IOLs have dislocated or subluxed and there has been no erosion of the subconjunctival haptics. CONCLUSIONS: Scleral fixation of IOLs using trocar cannulas or scleral tunnels is an effective surgical option for the treatment of aphakia or IOL dislocation. Both techniques result in significant visual improvement with minimal postoperative complications.

RESUMO

BACKGROUND/OBJECTIVE: Investigate real-world patients receiving faricimab for the treatment of neovascular age-related macular degeneration (nAMD). SUBJECTS/METHODS: Multicenter, retrospective chart review was conducted on patients treated with faricimab for nAMD from February 2022 to September 2022. Collected data includes background demographics, treatment history, best-corrected visual acuity (BCVA), anatomic changes, and adverse events as safety markers. The main outcome measures are changes in BCVA, changes in central subfield thickness (CST) and adverse events. Secondary outcome measures included treatment intervals and presence of retinal fluid. RESULTS: After one injection of faricimab, all eyes (n = 376), previously-treated (n = 337) and treatment-naïve (n = 39) eyes demonstrated a + 1.1 letter (p = 0.035), a + 0.7 letter (p = 0.196) and a + 4.9 letter (p = 0.076) improvement in BCVA, respectively, and a - 31.3 µM (p < 0.001), a - 25.3 µM (p < 0.001) and a - 84.5 µM (p < 0.001) reduction in CST, respectively. After three injections of faricimab, all eyes (n = 94), previously-treated (n = 81) and treatment-naïve (n = 13) eyes demonstrated a + 3.4 letter (p = 0.03), a + 2.7 letter (p = 0.045) and a + 8.1 letter (p = 0.437) improvement in BCVA, and a - 43.4 µM (p < 0.001), a - 38.1 µM (p < 0.001) and a - 80.1 µM (p < 0.204) reduction in CST, respectively. One case of intraocular inflammation was observed after four injections of faricimab and resolved with topical steroids. One case of infectious endophthalmitis was treated with intravitreal antibiotics and resolved. CONCLUSIONS: Faricimab has demonstrated improvement or maintenance of visual acuity for patients with nAMD, along with rapid improvement of anatomical parameters. It has been well-tolerated with low incidence of treatable intraocular inflammation. Future data will continue to investigate faricimab for real-world patients with nAMD.

RESUMO

PURPOSE: To present four cases of posterior ophthalmic manifestations associated with a temporal relationship to SARS-CoV-2 vaccination. METHODS: Retrospective case series with a review of clinical findings. RESULTS: Four patients presented with various posterior ophthalmic findings including uveitis, maculopathy, and optic neuropathy. Each of their clinical courses varied in terms of ophthalmic imaging and exam findings. CONCLUSION: The coronavirus disease 2019 (COVID-19) pandemic has ushered in a new wave of challenges to healthcare, epidemiological endeavors, and widespread vaccination efforts. Novel vaccines have been developed for the SARS-CoV-2 virus, including both mRNA and viral vector-based platforms. The ocular manifestations and side effects related to the SARS-CoV-2 vaccine is not well established or understood. There may be an association between vaccination and posterior ophthalmic manifestations.

RESUMO

PURPOSE: To describe the clinical features and surgical outcomes of patients experiencing a spontaneous conversion of a lamellar macular hole (LMH) to a full-thickness macular hole (FTMH). DESIGN: Retrospective, multicenter, observational case series. PARTICIPANTS: Patients with LMH who experienced a spontaneous conversion to FTMH and underwent FTMH surgery. METHODS: Clinical charts and OCT features of 20 eyes of 20 patients were reviewed. MAIN OUTCOME MEASURES: OCT features and surgical outcomes of FTMH derived from LMH. RESULTS: The mean baseline visual acuity (VA) was 0.21 ± 0.19 logarithm of the minimum angle of resolution (logMAR) (20/32 Snellen equivalent [SE]). Epiretinal proliferation was noted in 18 eyes (90%), and 14 eyes (75%) had an epiretinal membrane. At the diagnosis of FTMH, the mean VA decreased to 0.61 ± 0.50 logMAR (20/81 SE) (P = 0.001). The mean FTMH diameter was 224.4 ± 194.8 µm, with 15 (75%) small (≤250 µm), 2 (10%) medium (>250-≤400 µm), and 3 (15%) large (>400 µm) FTMHs. Eighteen (90%) FTMHs were sealed after 1 surgery, and 2 (10%) required an additional procedure. At the last follow-up, the mean VA was increased to 0.29 ± 0.23 logMAR (20/38 SE) (P = 0.003), but did not significantly differ from the baseline VA (P = 0.071). CONCLUSIONS: Patients with LMH may develop an FTMH with no evidence of vitreomacular traction. A tangential traction from an epiretinal membrane may contribute to its genesis, but a progressive loss of retinal tissue and an inherent weakness of the foveal architecture in LMH eyes could be sufficient. Most FTMHs derived from LMH had a small diameter, showed epiretinal proliferation, showed limited retinal hydration, and were associated with relatively poor surgical outcomes compared with idiopathic FTMH.

RESUMO

PURPOSE: To compare the rates of infectious endophthalmitis following intravitreal injection of ranibizumab using prefilled syringes vs conventional preparation. DESIGN: Multicenter retrospective cohort study. METHODS: All eyes receiving intravitreal injection of 0.5 mg ranibizumab for retinal vascular diseases at 10 retina practices across the United States (2016 to 2017) and Japan (2009 to 2017) were included. The total numbers of eyes and injections were determined from billing codes. Endophthalmitis cases were determined from billing records and evaluated with chart review. Primary outcome was the rate of postinjection acute endophthalmitis. Secondary outcomes were visual acuity and microbial spectrum. RESULTS: A total of 243 754 intravitreal 0.5 mg ranibizumab injections (165 347 conventional and 78 407 prefilled) were administered to 43 132 unique patients during the study period. In the conventional ranibizumab group, a total of 43 cases of suspected endophthalmitis occurred (0.026%; 1 in 3845 injections) and 22 cases of culture-positive endophthalmitis occurred (0.013%; 1 in 7516 injections). In the prefilled ranibizumab group, 12 cases of suspected endophthalmitis occurred (0.015%; 1 in 6534 injections) and 2 cases of culture-positive endophthalmitis occurred (0.0026%; 1 in 39 204 injections). Prefilled syringes were associated with a trend toward decreased risk of suspected endophthalmitis (odds ratio 0.59; 95% confidence interval 0.31-1.12; P = .10) and a statistically significant decreased risk of culture-positive endophthalmitis (odds ratio 0.19; 95% confidence interval 0.045-0.82; P = .025). Average logMAR vision loss at final follow-up was significantly worse for eyes that developed endophthalmitis from the conventional ranibizumab preparation compared to the prefilled syringe group (4.45 lines lost from baseline acuity vs 0.38 lines lost; P = .0062). Oral-associated flora was found in 27.3% (6/22) of conventional ranibizumab culture-positive endophthalmitis cases (3 cases of Streptococcus viridans, 3 cases of Enterococcus faecalis) compared to 0 cases in the prefilled ranibizumab group. CONCLUSION: In a large, multicenter, retrospective study the use of prefilled syringes during intravitreal injection of ranibizumab was associated with a reduced rate of culture-positive endophthalmitis, including from oral flora, as well as with improved visual acuity outcomes.

RESUMO

PURPOSE: Secondary intraocular lens (IOL) placement in uveitic eyes is challenging. We describe a series of sclerally fixated IOLs using a transconjunctival sutureless (SIS) technique in eyes with history of uveitis. METHODS: This is an interventional, retrospective, consecutive case series. RESULTS: Five patients with a history of well-controlled uveitis were included. All underwent vitrectomy, with removal of residual lens fragments if necessary. All received pre-, intra- and perioperative steroids, which were slowly tapered over the weeks after the surgery. If possible the dislocated IOL was rescued; otherwise, insertion of a new three-piece IOL was made. Postoperatively, all IOLs remained centered and haptics covered by conjunctiva without dislocation, erosion, or scleral thinning. There were no significant complications related to the surgery. Overall, the mean preoperative visual acuity was improved from logMAR 2.09 preoperatively to 0.59 postoperatively, which was statistically significant (p = 0.015). All eyes were deemed quiet at follow-up and none required escalation of therapy for long-term uveitis control. CONCLUSION: SIS IOL fixation is a safe and effective option for well-controlled uveitic eyes.

RESUMO

PURPOSE: To analyse the clinical characteristics and treatment outcomes of choroidal neovascular membranes (CNVM) in paediatric subjects at three paediatric retina referral centres. METHODS: Medical charts of patients aged 18 years or less with a diagnosis of CNVM were retrospectively reviewed. The demographic profile, laterality, presenting complaint, corrected vision, underlying pathology, fundus, fundus fluorescein angiogram and optical coherence tomogram (OCT) were analysed. CNVM type, frequency, treatment indications, recurrences and final visual acuity were noted. RESULTS: There were a total of 35 subjects (43 eyes) with a mean age of 11.2 years. The CNVMs were mostly type 2 (90.0%), classic (90.9%), subfoveal (59.09%) and active (84.1%). Best vitelliform macular dystrophy was found to be the most common association (32.5%). Intravitreal injection of an anti-vascular endothelial growth factor (VEGF) agent was the initial therapy of choice in all. Eyes with CNVMs responsive to anti-VEGF alone required a mean of 2.11 injections. Patients with recurrent disease (21.21%) had an average of 1.14 episodes per eye. While 50% of recurrent CNVMs stabilised with repeat anti-VEGF treatment, the remaining patients required photodynamic therapy, laser or surgery. CONCLUSION: Paediatric CNVMs in this series differed from those in the adult population with regard to aetiology, OCT and angiographic characteristics, treatment response and rate of recurrence.

RESUMO

PURPOSE: To report the chorioretinal coloboma, and its association with increased risk of retinal detachment (RD) and choroidal neovascularization (CNV). METHODS: This retrospective case series included eyes with chorioretinal coloboma diagnosed between 1995 and 2014 with a focus on RD and CNV as related complications. Cases of CNV were managed with laser photocoagulation or intravitreal injection of bevacizumab. For eyes with CNV, therapeutic success was defined as resolution of the subretinal hemorrhage on fundus examination and resolution of the subretinal and intraretinal fluid on optical coherence tomography (OCT). For eyes with RD, anatomic success following surgical intervention was defined as attachment of the retina at the last follow-up visit. RESULTS: Fifty-one eyes of 31 patients with chorioretinal coloboma were identified for review. Bilateral chorioretinal coloboma was present in 64.5% of subjects. RD developed in 15 eyes (29.4%). Among 15 eyes with RD, 4 eyes (27%) had retinal breaks identified within the coloboma, 5 eyes (33%) had retinal breaks outside the coloboma, 2 eyes (13%) showed retinal breaks both inside and outside the coloboma, and in 4 eyes (27%) the causative retinal break was not localized. The overall rate of anatomic success after RD repair was 85.7%. CNV developed in 7 eyes (13.7%) and was located along the margin of the coloboma in all cases. CNV was bilateral in 2 of the 5 affected individuals (40%). CONCLUSION: RD and CNV were present in a high percentage of eyes with chorioretinal coloboma in these series. The frequent finding of retinal breaks outside the coloboma bed suggests that vitreoretinal interface abnormalities may play a role in development of RD in these eyes.

RESUMO

PURPOSE: To report the prevalence and surgical outcomes of macular holes (MHs) in eyes with age-related macular degeneration (AMD). DESIGN: Interventional, retrospective, consecutive case series. PARTICIPANTS: Patients with MH and concurrent non-neovascular (NNV) or neovascular (NV) AMD. METHODS: The records of 27 912 patients diagnosed with AMD between 2009 and 2014 at Associated Retinal Consultants were reviewed. Demographic data, visual acuity (VA), funduscopic examination, and optical coherence tomography were reviewed in those with a concurrent diagnosis of MH. MAIN OUTCOME MEASURES: The VA and MH closure status. RESULTS: A total of 15 196 patients with NNV and 12 716 patients with NV AMD were identified. A total of 199 eyes (0.7%) had MHs (160 NNV [1.1%]; 39 NV [0.3%]). Mean time to diagnosis of MH after the initial visit was 11.2 months (7.1 NNV; 24.8 NV). A total of 127 eyes underwent surgical repair (106 NNV; 21 NV). The final closure rate in those who underwent vitrectomy was 89.8% (91.5% NNV; 81.0% NV) and 25.0% in those who were observed (18.5% NNV, P < 0.0001; 44.4% NV, P = 0.02). Preoperative logarithm of the minimum angle of resolution VAs in NNV and NV AMD was 0.8±0.4 and 0.8±0.5, respectively, and final VA was 0.6±0.5 (P < 0.001) and 0.9±0.6 (P = 0.52), respectively. Mean follow-up time was 5.0 years. CONCLUSIONS: The prevalence of MH was higher in eyes with NNV AMD than in those with NV AMD. The surgical closure rate was comparable in both groups, but VA improvement reached statistical significance only in the NNV AMD group.
