Visual acuity changes in the preoperative period in patients undergoing cataract surgery.

OBJECTIVE: This study quantifies change in best visual acuity (BVA) over the preoperative period and assesses factors associated with postoperative outcomes. DESIGN: Retrospective chart review conducted at a single institution. PARTICIPANTS: A total of 691 patients underwent cataract surgery and had a preoperative assessment 0-30 days prior to surgery following their surgical evaluation. METHODS: Baseline demographics and past medical and clinical data were collected through electronic medical record query. BVA was noted at initial surgical evaluation, preoperative assessment, and nearest postoperative assessment. RESULTS: A total of 691 patients (911 eyes) were included with mean BVAs at the initial evaluation, preoperative assessment, and postoperative assessment of 68.3 ± 16.8, 64.6 ± 18.5, and 81.1 ± 12.0 ETDRS letters, respectively. Mean BVA was significantly higher postoperatively compared with the preoperative assessment and initial evaluation (p < 0.0001). There was a mean of 53.8 days between initial surgical evaluation and surgery date and a mean of 49.9 days between the preoperative assessment and initial surgical evaluation. The mean interval between the preoperative assessment and surgery was 11.7 days. In the preoperative period, 9.1% of eyes experienced worsening of BVA by >3 eyes and 0.9% experienced improvement of BVA by >3 lines. Time to surgery was significantly associated with change in postoperative BVA (effect size, -0.03 ETDRS letters; p = 0.015) but was not significant on multiple linear regression. BVA at initial evaluation, glaucoma, and glaucoma surgery were all significantly associated with postoperative outcomes. CONCLUSION: Most eyes experienced stable vision in the preoperative period for cataract surgery. On average, patients with high BVAs at the time of initial surgical evaluation may be able to defer surgery without the risk of poorer surgical outcomes.

Clinical Utility of Spectral-Domain Optical Coherence Tomography Marker Disorganization of Retinal Inner Layers in Diabetic Retinopathy.

BACKGROUND AND OBJECTIVE: Disorganization of retinal inner layers (DRIL) is a potential spectral-domain optical coherence tomography (SD-OCT) imaging biomarker with clinical utility in diabetic retinopathy (DR). PATIENTS AND METHODS: A cross-sectional study was conducted at a large academic center. The cohort was composed of 1,175 patients with type 2 diabetes with and without retinopathy on initial examination between September 2009 and January 2019 (n = 2,083 eyes). DR risk and progression factors were obtained from the medical record. Trained graders masked to patients' clinical histories evaluated SD-OCT scans for DRIL. RESULTS: Of 2,083 eyes, 28.1% (n = 585) demonstrated presence of DRIL with high interrater reliability (K = 0.88, 95% CI 0.86-0.90). DRIL was associated with worse visual acuity (VA) (P < 0.001) and DR severity (P < 0.0001). Insulin users had more severe DR (P < 0.0001). DR-related factors, race (Black, White) and sex (male) were significantly associated with DRIL (P < 0.05). CONCLUSIONS: DRIL was strongly associated with DR severity and worse VA, supporting its utility as an unfavorable prognostic indicator. [Ophthalmic Surg Lasers Imaging Retina 2023;54:692-700.].

Patient-Reported Complications after Intravitreal Injection and Their Predictive Factors.

PURPOSE: The intravitreal injection (IVI) of pharmacologic agents is the most commonly performed ocular procedure and is associated with a host of complications. Most IVI-related complications data are derived from randomized controlled clinical trials, which report a high adverse event rate. The nature of these protocol-driven trials limit their applicability to the diverse circumstances seen in routine clinical practice. The goal of this study was to determine the prevalence of patient-reported IVI-related complications, their risk factors, and the manner in which patients sought treatment at a tertiary eye care center. DESIGN: Retrospective, institutional review board-approved study. PARTICIPANTS: Forty-four thousand seven hundred thirty-four injections in 5318 unique patients at the Cleveland Clinic Cole Eye Institute from 2012 through 2016. METHODS: Intravitreal injection. MAIN OUTCOME MEASURES: Complication occurrence within 15 days of injection. RESULTS: From 2012 through 2016, a total of 44734 injections were performed in 5318 unique patients. Overall, complication rates were low, representing 1.9% of all injections, with 1031 unique complications in 685 patients (12.9%). The most common minor complications, or those not requiring intervention, were irritation (n = 312) and subconjunctival hemorrhage (n = 284). The most common serious complications, or those requiring intervention, were corneal abrasion (n = 46) and iritis (n = 31). Most complications (66%) were managed adequately by a telephone or Epic (Epic Systems Corp., Verona, WI) electronic message encounter only. Importantly, no injection protocol parameter, such as type of anesthesia, preparation, or post-injection medication, increased the risk of a complication. However, a patient's gender, age, number of previous injections, and provider strongly influenced the risk of patient-reported complications. CONCLUSIONS: Overall, complication rates seen in routine clinical practice were low compared with clinical trial reporting. Providers should feel confident in the safety and administration of IVI during times when follow-up office visits and resources may be limited. When performing an IVI, factors such as a patient's gender, age, number of previous injections, and provider must be taken into account to ensure the best possible outcomes.

The COMS Randomized Trial of Iodine 125 Brachytherapy for Choroidal Melanoma: IV. Local Treatment Failure and Enucleation in the First 5 Years after Brachytherapy. COMS Report No. 19.

OBJECTIVE: To describe the frequency and predictors of local treatment failure and enucleation after iodine 125 (I125) brachytherapy in patients with choroidal melanoma treated and followed up in a large randomized clinical trial. DESIGN: Prospective, noncomparative, interventional case series within a randomized, multicenter clinical trial. PARTICIPANTS: Patients enrolled in the Collaborative Ocular Melanoma Study (COMS) trial of enucleation versus brachytherapy between February 1987 and July 1998; tumors measured 2.5 to 10.0 mm in apical height and no more than 16.0 mm in longest basal dimension. METHODS: I125 brachytherapy was administered via episcleral plaque according to a standard protocol. Follow-up ophthalmic evaluations, including ophthalmic ultrasound and fundus photography, were performed according to a standard protocol at baseline, every 6 months thereafter for 5 years, and subsequently at annual intervals. Survival analysis methods were used to estimate the cumulative risk of postirradiation treatment failure and enucleation. Factors associated with treatment failure and enucleation of plaqued eyes were evaluated using Cox proportional hazards analysis. MAIN OUTCOME MEASURES: Reports of enucleation and of local treatment failure, defined as tumor growth, recurrence, or extrascleral extension, derived from clinical reports based on echographic and photographic documentation. RESULTS: As of September 30, 2000, 638 of the 650 patients randomized to brachytherapy and so treated had been followed up for 1 year or longer, and 411 had been followed up for at least 5 years. Sixty-nine eyes were enucleated during the first 5 years after brachytherapy, and treatment failure was reported for 57 eyes. The Kaplan-Meier estimate of proportion of patients undergoing enucleation by 5 years was 12.5% (95% confidence interval [CI], 10.0%-15.6%); the risk of treatment failure was 10.3% (95% CI, 8.0%-13.2%). Treatment failure was the most common reason for enucleation within 3 years of treatment; beyond 3 years, ocular pain was most common. Risk factors for enucleation were greater tumor thickness, closer proximity of the posterior tumor border to the foveal avascular zone, and poorer baseline visual acuity in the affected eye. Risk factors for treatment failure were older age, greater tumor thickness, and proximity of the tumor to the foveal avascular zone. Local treatment failure was associated weakly with reduced survival after controlling for baseline tumor and personal characteristics (adjusted risk ratio, 1.5; P = 0.08). CONCLUSIONS: Local treatment failure and enucleation were relatively infrequent events after I125 brachytherapy within the COMS. Treatment failure typically occurred early and was associated weakly with poorer survival. The COMS randomized trial documented the absence of a clinically or statistically significant difference in survival for patients randomly assigned to enucleation versus brachytherapy. This analysis documents the efficacy of brachytherapy to achieve sustained local tumor control and to conserve the globe.

Eplerenone for the treatment of chronic central serous chorioretinopathy: 3-year clinical experience.

BACKGROUND/AIMS: The efficacy of mineralocorticoid receptor antagonist eplerenone to treat chronic central serous chorioretinopathy (CSCR) has been established. However, previous studies have been limited by small cohort size and short follow-up duration. This study aims to report 3-year clinical outcomes of patients treated with eplerenone for chronic CSCR. METHODS: Institutional review board-approved retrospective chart analysis at a single institution from 2012 to 2018. Baseline best-corrected visual acuity and anatomical measurements related to degree of subretinal fluid (SRF) were collected at eplerenone initiation. Follow-up data were collected at the closest date to 12, 24 and 36 months. RESULTS: Data were obtained for 100 eyes of 83 patients at 1-year (mean 11.18 ± 4.00 months), 49 eyes at 2-year (24.01 ± 3.33 months) and 33 eyes at 3-year (mean 35.5 ± 7.89 months) follow-up visits. The rate of complete SRF resolution was 31%, 28% and 33%, respectively. At final follow-up, logarithm of the minimum angle of resolution visual acuity change from baseline was +0.10 ± 0.24 (p = 0.130). Average change from baseline at final follow-up for central subfield thickness was -97 ± 140.6 µm (p < 0.001), cube volume was -1.07 ± 1.71 mm3 (p < 0.001), macular thickness -28. 5 ± 47.5 µm (p < 0.001), maximum SRF height was -95.6 ± 160.5 µm (p < 0.001) and maximum SRF diameter was -1169.0 ± 1638.7 µm (p = 0.008). CONCLUSION: Anatomical improvement occurs primarily within the first year of eplerenone treatment for chronic CSCR.

Detection of Choroidal Neovascular Membrane Beneath Pigment Epithelial Detachment Using SD-OCTA.

BACKGROUND AND OBJECTIVE: To identify choroidal neovascular membrane (CNVM) associated with spectral-domain optical coherence tomography (SD-OCT)-defined pigment epithelial detachment (PED) using SD-OCT angiography (SD-OCTA). PATIENTS AND METHODS: Sixty-nine patients with same-day OCT and OCTA imaging were reviewed, and 41 eyes of 29 patients with PEDs were included. OCTs were analyzed for PED type, fluid, and subretinal hyperreflective material (SHRM). RESULTS: Twenty-seven eyes (66%) demonstrated CNVM on OCTA beneath all subtypes of PED. Twenty-two eyes (75.9%) with fluid or SHRM demonstrated CNVM on OCTA (P = .036). Fluid corresponded in a statistically significant manner with treatment (P = .0032), whereas SHRM did not (P = .613). OCTA-defined CNVM showed borderline statistically significant correlation to treatment (P = .05). Increased choroidal flow signal seen in 50% of eyes did not demonstrate statistically significant correlation to the presence of fluid on SD-OCT (P = .2798) or treatment decision (P = .678). A subset of 14 untreated eyes with CNVM was analyzed, 21% of which required treatment at subsequent visits. CONCLUSIONS: OCTA-defined CNVM was seen in all subtypes of PED in clinically active and inactive disease. The role of OCTA in predicting need for treatment remains to be established.

A Prospective Randomized Comparative Dosing Trial of Ranibizumab In Bevacizumab-Resistant Diabetic Macular Edema: The REACT Study.

PURPOSE: To assess the efficacy of ranibizumab for persistent diabetic macular edema (DME) previously treated with bevacizumab and compare monthly vs treat-and-extend (TAE) dosing. DESIGN: 12-month, open-label, prospective randomized comparative dosing study. PARTICIPANTS: 27 participants with persistent foveal-involving DME recently treated with bevacizumab. METHODS: All subjects were to receive three initial monthly 0.3 mg ranibizumab injections before randomization to monthly (n=15) or TAE (n=12) injection protocols over 12 months. Treatment interval was extended by two weeks up to a maximum interval of 12 weeks in the TAE group if central subfield thickness (CST) was ≤ 300 µm or complete absence of intraretinal or subretinal fluid on the macular cube was observed. Follow-up interval was decreased by 2 weeks if CST increased above 300 µm with associated intraretinal and/or subretinal fluid. MAIN OUTCOME MEASURES: Change in Early Treatment of Diabetic Retinopathy Study (ETDRS) best corrected visual acuity (BCVA), CST, adverse events. RESULTS: Prior to study enrollment, subjects received an average of 8.6 bevacizumab injections. At month 12, mean ETDRS BCVA improved by + 5.3 letters (p<0.05) and mean CST decreased by -99.6 µm (p<0.01) in all patients. At study exit, 18.5 % of subjects gained ≥ 3 lines of vision and 3.7% of subjects lost ≥ 3 lines. Patients treated via the TAE protocol gained +8.4 letters and decreased CST by -120.2 µm whereas those treated by monthly injection gained +2.7 letters and decreased CST by -83.1 µm at month 12. CONCLUSIONS: Following conversion to ranibizumab in eyes with persistent DME refractory to bevacizumab, significant functional and anatomic improvements were noted. Visual and anatomical outcomes were similar in TAE and monthly treatment protocols.

36-Month Evaluation of Intravitreous Aflibercept Injection for Wet Age-Related Macular Degeneration in Patients Previously Treated With Ranibizumab or Bevacizumab.

BACKGROUND AND OBJECTIVE: In the ASSESS study, patients with neovascular age-related macular degeneration transitioned from other anti-vascular endothelial growth factor therapies to intravitreous aflibercept (Eylea; Regeneron, Tarrytown, NY) injections (IAI). The purpose was to determine the 36-month outcomes following the change from a fixed 24-month IAI dosing regimen to a routine clinical practice regimen. PATIENTS AND METHODS: Patients were treated with a fixed bimonthly regimen for the first 2 years. In the third year, patients were managed according to routine clinical practice. RESULTS: A total of 18 patients completed the 36 months and were considered for statistical analyses. At 36 months, a nonsignificant decrease of -37.8 µm in central subfield thickness and a nonsignificant gain of 5.8 letters from baseline were observed. CONCLUSION: Despite the significant visual and anatomical gains observed in the 2 years of fixed-dosing IAI, there was gradual decline in these improvements when patients were transitioned to a variable regimen.

The Prevalence of Adverse Ocular Hemorrhagic Events in Patients Utilizing Oral Anticoagulant and Antiplatelet Therapy in Routine Clinical Practice.

BACKGROUND AND OBJECTIVE: Previous literature assessing ocular hemorrhagic complications of anticoagulant/antiplatelet medications in routine clinical practice is limited. This study evaluates the prevalence of spontaneous ocular hemorrhagic events associated with anticoagulation/antiplatelet therapy. PATIENTS AND METHODS: A retrospective study was performed to identify patients taking anticoagulants (rivaroxaban [Xarelto; Janssen Pharmaceuticals, Beerse, Belgium], bivalirudin [Angiomax; The Medicines Company, Parsippany, NJ], lepirudin [Refludan; Bayer HealthCare Pharmaceuticals, Berlin, Germany], dabigatran [Pradaxa; Boehringer Ingelheim, Ingelheim am Rhein, Germany], and argatroban) and antiplatelet agents (clopidogrel [Plavix; Bristol-Myers Squibb, New York City, NY], prasugrel [Effient; Lilly Medical, Indianapolis, IN], and ticagrelor [Brilinta; AstraZeneca, Cambridge, UK]) who presented for an eye examination. Location of hemorrhage, relevant systemic and ocular comorbidities, baseline demographics, and concomitant aspirin use were noted. RESULTS: A total of 44 patients with spontaneous ocular hemorrhage were identified. Thirty patients had a single episode, whereas 14 patients had multiple episodes (two or more hemorrhagic events). Prevalence of spontaneous ocular hemorrhage on prasugrel (7.2%) and rivaroxaban (3.1%) was higher compared to dabigatran (1.9%), clopidogrel (2.0%), and ticagrelor (2.7%). CONCLUSION: Prevalence of spontaneous ocular hemorrhage with use of anticoagulant/antiplatelet agents is higher in routine clinical practice as compared to previously reported literature.

Long-Term Assessment of Macular Atrophy in Patients with Age-Related Macular Degeneration Receiving Anti-Vascular Endothelial Growth Factor.

PURPOSE: Although intravitreal anti-vascular endothelial growth factor (VEGF) injection has become the mainstay treatment for neovascular age-related macular degeneration (nAMD), emerging studies suggest that anti-VEGF may be correlated with the development of macular atrophy (MA) in chronic therapy. The purpose of the current study is to determine the prevalence and progression of MA in nAMD treated with chronic anti-VEGF in a routine clinical practice. DESIGN: Retrospective cohort. PARTICIPANTS: Patients with nAMD who were previously treatment-naïve and treated with anti-VEGF at the Cole Eye Institute for at least 4 years. METHODS: This is chart review on anti-VEGF treated patients with nAMD with baseline and yearly follow-up spectral domain-OCT for at least 4 years. Retinal pigment epithelium subillumination analysis was used to automate identification of atrophy. Segmentation errors were manually corrected by 4 expert raters using a standardized grading protocol to quantify MA size. Patient baseline characteristics and treatment course were analyzed to identify predictive factors for the development of MA. MAIN OUTCOME MEASURES: MA growth rate and prevalence in cohorts with and without baseline atrophy. RESULTS: A total of 79 eyes from 66 patients (79.8±7.4 years, 63% were female) with nAMD and 4 years of follow-up with anti-VEGF injections were identified. The mean baseline visual acuity was 0.48±0.25 logarithm of the minimum angle of resolution (20/60 Snellen equivalent), and the mean final visual acuity was 0.48±0.49 logarithm of the minimum angle of resolution (20/44 Snellen equivalent, P = 0.23). The average number of injections was 19.8±9.8. MA was observed in 12.7% of eyes at baseline with an average annual growth rate of 0.7±0.5 mm2. In eyes without baseline MA, atrophy developed in 53.6% eyes by year 4 with a growth rate of 0.2±0.4 mm2 per year. Multiple linear regression analysis revealed that the progression of MA was positively correlated with age (R = 0.02, P = 0.009). CONCLUSIONS: More than half of patients with nAMD treated with anti-VEGF injections for 4 years developed new MA. Atrophy progression was most strongly correlated with age, which suggests that baseline disease characteristics may be more predictive of MA progression than cumulative anti-VEGF treatment.
