RESUMO
PURPOSE: To evaluate anatomic outcomes and surgeon response following the use of microserrated (Sharkskin, Alcon, Forth Worth, TX) internal limiting membrane (ILM) forceps compared with conventional (Grieshaber; Alcon) ILM forceps for peeling of the ILM. METHODS: Patients were prospectively assigned in a 1:1 randomized fashion to undergo ILM peeling using microserrated forceps or conventional forceps. Rates of retinal hemorrhages, deep retinal grasps, ILM regrasping, time to ILM removal, and surgeon questionnaire comparing the use of microserrated and conventional ILM forceps were analyzed. RESULTS: A total of 90 eyes of 90 patients were included in this study. The mean number of deep retinal grasps was higher in the conventional forceps group (1.51 ± 1.70 vs. 0.33 ± 0.56, respectively [P < 0.0001]). The mean number of failed ILM grasps was higher with conventional forceps (6.62 ± 3.51 vs. 5.18 ± 2.06 [P = 0.019]). Microserrated forceps provided more comfortability (lower number) in initiating the ILM flap (2.16 ± 0.85 vs. 1.56 ± 0.76, P < 0.001), comfortability in regrasping the ILM flap (2.51 ± 1.01 vs. 1.98 ± 0.89, P = 0.01), and comfortability in completing the ILM flap (2.42 ± 1.03 vs. 1.84 ± 1.02, P = 0.01). CONCLUSION: Surgeons utilizing the microserrated forceps experienced fewer deep retina grasps and fewer failed ILM grasps compared with conventional ILM forceps. The microserrated forceps was also a more favorable experience subjectively among the surgeons.

PURPOSE: To assess visual acuity and optical coherence tomography outcomes after repair of secondary epiretinal membrane (ERM) after prior laser retinopexy for retinal tear with or without localized retinal detachment. METHODS: Retrospective, consecutive series. A previously described optical coherence tomography grading scheme was used for imaging analysis. RESULTS: Forty-two eyes of 42 patients were included, of which 16 (38.1%) had a concurrent localized retinal detachment. Mean logMAR visual acuity prelaser retinopexy was 0.15 ± 0.13 (Snellen 20/28), which worsened to 0.56 ± 0.42 (Snellen 20/72) before ERM surgery (P < 0.001). The mean visual acuity improved to 0.36 ± 0.30 (Snellen 20/45, P < 0.001) 3 months postsurgery and to 0.31 ± 0.32 (Snellen = 20/40, P < 0.001) at the final follow-up. Most eyes exhibited advanced ERM characteristics (n = 19 [45.2%] Stage 3 and n = 15 [35.7%] Stage 4 characteristics). The presence of inner microcystic changes (P = 0.008) and ellipsoid zone disruption (P = 0.009) at postoperative Month 3 were associated with worse final visual acuity. Eyes undergoing ERM surgery ≤180 days from laser retinopexy (n = 16, 38.1%) were younger (P = 0.024) and more likely to have Stage 4 ERM characteristics (P = 0.001). CONCLUSION: Secondary ERM after laser retinopexy may occur rapidly (<180 days) and exhibit significant anatomic alterations. The presence of inner microcystic changes and ellipsoid zone disruption postoperatively were optical coherence tomography features associated with worse final visual acuity.

PURPOSE: To describe the prevalence, management, and outcomes of rhegmatogenous retinal detachment (RRD) after incisional glaucoma filtering surgery. METHODS: All patients with a history of trabeculectomy or glaucoma drainage device surgery who were subsequently diagnosed with an RRD from January 1, 2016, to January 1, 2021, at the Wills Eye Hospital were identified. RESULTS: Forty-six eyes met the inclusion criteria. The mean age was 60.7 ± 19.6 years, and 15 patients (32.6%) were female. Of all eyes, 34 (73.9%) were diagnosed with primary open-angle glaucoma. The mean time from most recent incisional glaucoma surgery to RRD diagnosis was 1,133 ± 1,644 days. There were 19 eyes (41.3%) with preoperative proliferative vitreoretinopathy (9 eyes [19.6%] with Grade C proliferative vitreoretinopathy) and 35 eyes (76.1%) had macula-off RRD at the time of presentation. At RRD presentation, 4 eyes (8.7%) had concomitant endophthalmitis, 5 (10.9%) had concurrent choroidal detachment, and 2 (4.7%) had concurrent vitreous hemorrhage. Primary vitrectomy was performed in most (91.3%) cases. Silicone oil tamponade was often required (71.1%). The single surgery success rate was 65.2% (30 of 46). The mean preoperative logarithm of the minimum angle of resolution visual acuity was 1.72 ± 0.78 (Snellen acuity 20/1,050), and the mean final postoperative logarithm of the minimum angle of resolution was 1.59 ± 0.89 (20/778, P = 0.2853). Of glaucoma surgeries performed, the 5-year prevalence of RRD was 0.71% (26 of 3,664, 95% Poisson confidence interval 0.48%-1.04%). CONCLUSION: The 5-year prevalence of RRDs after trabeculectomy or glaucoma drainage device was 0.71%. Most patients presented with macula-involving detachments, often with proliferative vitreoretinopathy. Anatomical and visual outcomes were poor.

PURPOSE: To report factors affecting the retinal redetachment rate after silicone oil removal (SOR) following rhegmatogenous retinal detachment (RRD) repair. METHODS: Retrospective cohort study from December 1, 2014, to March 1, 2020, of 205 consecutive patients treated for RRD with silicone oil (SO) tamponade and subsequent SOR with at least 6-month follow-up. Primary outcome measure was the rate of retinal redetachment after SOR. RESULTS: The retinal redetachment rate after SOR was 18.5%. Preoperative macula and lens status, proliferative vitreoretinopathy, previous retinectomy, retinal detachment size, concomitant phacoemulsification, previous scleral buckling, and endolaser during SOR did not affect the redetachment rate after SOR. Previous SO exchange was associated with increased redetachment (OR 2.53, 95% CI [1.11-5.80], P = 0.0278). Twelve months of SO tamponade had lower redetachment rates compared with 3 months (OR 0.25, 95% CI [0.04-0.09], P = 0.048). Shorter SO tamponade (3 vs. 12 months) had better final visual outcomes after SOR (0.80 ± 0.61 vs. 1.41 ± 0.66, P < 0.0001). CONCLUSION: No preoperative or intraoperative factors in this analysis influenced the risk of redetachment after SOR except duration of SO tamponade and previous SO exchange. Although longer SO tamponade duration may be associated with lower rates of redetachment, visual outcomes may be worse.

Objective: To evaluate the attitudes, beliefs, and practice patterns of vitreoretinal specialists regarding the utilization of telemedicine during the COVID-19 pandemic, and to identify features which may predict future telemedicine use. Methods: An 11-question anonymous survey was completed electronically in July 2020 by vitreoretinal specialists practicing in the United States. Results: The survey response rate was 13.0% (361/2,774). Thirty-five respondents (9.7%) had used telemedicine before March 1, 2020; after March 1, 2020, 170 (47.1%) reported using telemedicine (p < 0.001). Of the 170 respondents who reported telemedicine use, a majority (65.3%;111/170) performed 0-5 patient visits per week. Female retina specialists, younger physicians, and those with prior telemedicine usage were more likely to use telemedicine. Barriers to telemedicine use included concern for misdiagnosis (332/361, 92.0%), inability to obtain optical coherence tomography imaging (330/361, 91.4%), inability to obtain fundus imaging (327/361, 90.6%), lack of access to and/or comfort with the technology (261/361, 72.3%), potential legal liability (229/361, 63.4%), and low reimbursement (227/361, 62.9%). The majority of respondents (225/361; 62.3%) reported that telemedicine without ancillary imaging was not an acceptable way to evaluate patients. However, 59.2% (214/361) would find telemedicine acceptable if remote imaging was available. Conclusions: The pandemic led to a rapid adoption of telemedicine by vitreoretinal specialists. The majority of specialists using telemedicine performed five or fewer visits per week. The availability of remote imaging may increase confidence in clinical outcomes with a subsequent increase in utilization of telemedicine by vitreoretinal specialists.

PURPOSE: To investigate the effect of the coronavirus disease 2019 (COVID-19) pandemic on the clinical presentation of acute, primary rhegmatogenous retinal detachment (RRD). DESIGN: Single-center, consecutive case series with historical controls. PARTICIPANTS: Consecutive patients seeking treatment for primary RRD in a 50-day period during the COVID-19 pandemic (March 9-April 27, 2020) and the corresponding 50-day period during the previous year (March 4-April 22, 2019) in the United States. METHODS: The cohorts were compared to assess demographic variables and clinical presentations. Multivariate logistic regression was used to identify factors predictive of presenting macular attachment status. MAIN OUTCOME MEASURES: The primary outcome was the proportion of patients with macula-on RRD at presentation. Secondary outcomes included visual acuity (VA), duration of symptoms before presentation, proportion seeking treatment within 1 day of symptom onset, and presence of primary proliferative vitreoretinopathy (PVR). RESULTS: Eighty-two patients were included in the 2020 cohort compared with 111 patients in the 2019 primary control cohort. Demographic factors were similar between the groups. Significantly fewer patients demonstrated macula-on RRD in the 2020 cohort (20/82 patients [24.4%]) than in the 2019 cohort (55/111 patients [49.5%]; P = 0.001). Patients in the 2020 cohort showed worse median VA at presentation (1.00 logarithm of the minimum angle of resolution [logMAR; Snellen equivalent, 20/200] in 2020 vs. 0.48 logMAR [Snellen equivalent, 20/60] in 2019; P = 0.008), fewer patients sought treatment within 1 day of symptoms (16/80 patients [19.5%] in 2020 vs. 41/106 patients [36.9%] in 2019; P = 0.005), and a greater proportion demonstrated primary PVR (11/82 patients [13.4%] in 2020 vs. 5/111 patients [4.5%] in 2019; P = 0.03). In multivariate analysis, younger age (P = 0.03) and established patient status (P = 0.02) were independent predictors of macula-on status in the 2020 cohort. CONCLUSIONS: Patients with primary RRD during the 2020 COVID-19 pandemic were less likely to have macula-on disease and more likely to delay seeking treatment and to show worse vision and PVR.

PURPOSE OF REVIEW: The number of opioid-related overdose deaths has rapidly increased since 2000, increasing more than five-fold from 1999 to 2016. Although surgeons only write 10% of opioid prescriptions annually, with ophthalmologists writing only a fraction of this amount, all physicians need to be cognizant of the current opioid epidemic and ways to decrease unnecessary opioid prescriptions. RECENT FINDINGS: Previous work within ophthalmology has shown that retrobulbar anesthesia along with peri-operative intravenous or oral nonopioid analgesics can lead to decreased postoperative opioid use following ophthalmic surgery. Recent literature has shifted focus towards the use of opioid prescription guidelines in managing postoperative pain and decreasing the number of unnecessary opioids being prescribed by ophthalmologists. Overall, the frequency of opioid prescriptions may have gradually declined the past few years with such efforts, increased awareness, and new healthcare policies to monitor opioid prescriptions. However, ophthalmologists still continue to prescribe a substantial number of opioid medications, much of which may not be necessary. SUMMARY: This review serves as a tool to aid all ophthalmologists in managing postoperative pain. There is a recent trend in addressing the opioid epidemic and efforts are being made to limit the overprescribing of opioids. Continued efforts are still required by all ophthalmologists to address the current opioid epidemic.

PURPOSE: To evaluate serum beta-D-glucan (BDG) as a biomarker for endogenous fungal eye infection. METHODS: Retrospective case-control study of 88 patients with a BDG test and eye examination at UPenn (2013-2018). Cases had endogenous fungal chorioretinitis or endophthalmitis diagnosed by eye examination and confirmed with positive culture; controls were without these fungal eye findings. Charts were reviewed for BDG values, blood/vitreous cultures, and eye examinations. Outcomes were BDG sensitivity, specificity, positive predictive value, and negative predictive value for fungal chorioretinitis or endophthalmitis, using prespecified BDG cut-off points of ≥80, ≥250, and ≥500 pg/mL as test positive. RESULTS: Cases included six chorioretinitis and four endophthalmitis patients. Controls included 78 patients without chorioretinitis or endophthalmitis. Defining BDG ≥80 pg/mL as test positive, the BDG sensitivity (95% confidence interval) was 66.7% (22.3%-95.7%) for chorioretinitis and 100% (39.8%-100%) for endophthalmitis. The specificity was 74.4% (63.2%-83.6%) when BDG values ≥80 pg/mL were test positive, and 85.9% (76.2%-92.7%) when values ≥250 pg/mL were test positive. For a 1% endophthalmitis prevalence and BDG cut-off value of ≥80 pg/mL, the positive predictive value was 3.8% (2.4%-5.2%) and negative predictive value was 100% (99.1%-100%). CONCLUSION: For endogenous fungal endophthalmitis, BDG's sensitivity and specificity seem good and the negative predictive value is high; a larger ophthalmic study is indicated.

INTRODUCTION: Rhegmatogenous retinal detachments with inferior retinal breaks are believed to have a higher risk of recurrent rhegmatogenous retinal detachment. This study compared anatomic and visual outcomes between primary pars plana vitrectomy (PPV) and combination PPV with scleral buckle (PPV/SB) for rhegmatogenous retinal detachments with inferior retinal breaks. METHODS: This is an analysis of the Primary Retinal Detachment Outcomes study, a multi-institutional cohort study of consecutive primary rhegmatogenous retinal detachment surgeries from January 1, 2015, through December 31, 2015. The primary outcome was single-surgery success rate. Only eyes with inferior retinal breaks (one break in the detached retina between five and seven o'clock) were included. RESULTS: There were 238 eyes that met the inclusion criteria, 95 (40%) of which underwent primary PPV and 163 (60%) that underwent combined PPV/SB. The single-surgery success rate was 76.8% for PPV and 87.4% for PPV/SB (P = 0.0355). This remained significant on multivariate analysis (P = 0.01). Subgroup analysis showed that a superior single-surgery success rate of PPV/SB was especially noted in phakic eyes (85.2% vs. 68.6%; P = 0.0464). CONCLUSION: Retinal detachment with inferior retinal breaks had a higher single-surgery success rate if treated with PPV/SB compared with PPV alone, particularly in phakic eyes.

PURPOSE: To describe characteristics and outcomes of primary rhegmatogenous retinal detachment in older adults (age ≥ 80). METHODS: Consecutive patients with rhegmatogenous retinal detachment undergoing pars plana vitrectomy (PPV), scleral buckling (SB), or PPV/SB in the Primary Retinal Detachment Outcomes Study were evaluated. Outcome measures included single surgery anatomic success and visual acuity. RESULTS: Of 2,144 patients included, 125 (6%) were 80 years or older. Compared with younger patients (age 40-79), older adults were more likely to be pseudophakic (P < 0.001), have macula-off detachments (P < 0.001), and have preoperative proliferative vitreoretinopathy (P = 0.02). In older adults, initial surgery was PPV in 73%, PPV/SB in 27%, and primary SB in 0%. Single surgery anatomic success was 78% in older adults compared with 84% in younger patients (P = 0.03). In older adults, single surgery anatomic success was 74% for PPV and 91% for PPV/SB (P = 0.03). The final mean logMAR was lower for older adults (0.79 [20/125] vs. 0.40 [20/40], [P < 0.001]). In older adults, the final mean logMAR for eyes that underwent PPV was 0.88 (20/160) compared with 0.50 (20/63) for PPV/SB (P = 0.03). CONCLUSION: Octogenarians and nonagenarians presented with relatively complex pseudophakic rhegmatogenous retinal detachments. Single surgery anatomic success and visual outcomes were worse compared with younger patients, and PPV/SB had better outcomes compared with PPV alone.

PURPOSE OF REVIEW: A variety of techniques exist for secondary intraocular lens (IOL) implantation. Of note, scleral fixated intraocular lenses have become more popular with a variety of techniques, both with and without use of sutures. Herein, we focus on reviewing recently published studies describing the long-term outcomes of scleral fixation techniques. RECENT FINDINGS: Although initial papers describing novel techniques often report short-term outcomes, several studies have recently described intermediate and long-term outcomes for scleral fixated IOLs, albeit all being retrospective case series. Suture fixation methods with long-term follow-up, up to a minimum of 50 months, report dislocation rates between 0 and 15%. Sutureless scleral fixation techniques have increased in popularity the past several years. Although they appear to have a lower rate of IOL dislocation: several studies have reported 0% and one study 8%. The follow-up period for sutureless scleral fixation technique studies, however, is shorter with most studies reporting follow-up of less than a year. Rates of retinal detachment vary between individual studies, but are similar for both suture fixation and sutureless with the majority of studies reporting a rate between 0 and 5%. These studies show that long-term outcomes are important considerations in surgical decision-making. SUMMARY: Scleral fixation techniques have shown long-term durability and safety in recent retrospective studies. Comparison of techniques has been limited, and more robust studies may be required to provide stronger anatomic, functional, and comparative data.

PURPOSE OF REVIEW: The purpose of this review is to describe the current clinical landscape of potential future therapies for both nonexudative (dry) and exudative (wet) age-related macular degeneration (AMD). We highlight some of the more promising treatments that are furthest along in development. RECENT FINDINGS: Patients with dry AMD have long been hoping for a highly efficacious treatment that may slow disease progression or even help regain vision. Patients with wet AMD have many effective treatment options but still there are those who have suboptimal responses or are burdened by the high frequency of treatment. We detail exciting new concepts and targets for novel medications. Specifically, for dry AMD we discuss research looking at complement inhibition, neuroprotection, visual cycle modulators, cell-based therapies, and anti-inflammatory agents. For wet AMD we summarize new, potentially more durable anti-vascular endothelial growth factor agents, extended release options, and gene therapy. SUMMARY: There are promising new strategies for AMD. Many of the potential new treatments are in or have recently completed phase 2 or phase 3 clinical trials with promising results thus far, including some that have received US Food and Drug Administration approval. Additional therapeutic breakthroughs will likely continue to occur thanks to the number of clinical trials that are nearing the finish line.

PURPOSE: Advances in two-photon (2P) deep tissue imaging provide powerful options for simultaneously viewing multiple fluorophores within tissues. We determined imaging parameters for optimally visualizing three fluorophores in the human trabecular meshwork (TM) to simultaneously detect broad-spectrum autofluorescence and multiple fluorophores through a limited number of emission filters. METHODS: 2P imaging of viable human postmortem TM was conducted to detect Hoechst 33342-labeled nuclei, Alexa-568-conjugated phalloidin labeling of filamentous actin, and autofluorescence of the structural extracellular matrix (ECM). Emission detection through green (500-550 nm), near-red (565-605 nm), and far-red (590-680 nm) filters following 2P excitation at 750, 800, 850, and 900 nm was analyzed. Region-of-interest (ROI) image analysis provided fluorescence intensity values for each fluorophore. RESULTS: Red-channel Alexa 568 fluorescence was of highest intensity with 2P 750 nm and 800 nm excitation. Alexa 568 was imperceptible with 900 nm excitation. With excitation at 750 nm and 800 nm, Hoechst 33,342 intensity swamped autofluorescence in the green channel, and marked bleed-through into red channels was seen. 850 nm excitation yielded balanced Hoechst 33342 and autofluorescence intensities, minimized their bleed-through into the far-red channel, and produced reasonable Alexa 568 intensities in the far-red channel. CONCLUSIONS: 2P excitation at 850 nm and long-wavelength emission detection in the far-red channel allowed simultaneous visualization of the specific mix of endogenous and exogenous fluorophores with reasonably balanced intensities while minimizing bleed-through when imaging the human TM.

BACKGROUND/AIMS: To compare risk factors for poor visual outcomes in patients undergoing primary rhegmatogenous retinal detachment (RRD) repair and to develop a scoring system. METHODS: Analysis of the Primary Retinal detachment Outcomes (PRO) study, a multicentre interventional cohort of consecutive primary RRD surgeries performed in 2015. The main outcome measure was a poor visual outcome (Snellen VA ≤20/200). RESULTS: A total of 1178 cases were included. The mean preoperative and postoperative logMARs were 1.1±1.1 (20/250) and 0.5±0.7 (20/63), respectively. Multivariable logistic regression identified preoperative risk factors predictive of poor visual outcomes (≤20/200), including proliferative vitreoretinopathy (PVR) (OR 1.26; 95% CI 1.13 to 1.40), history of antivascular endothelial growth factor (VEGF) injections (1.38; 1.11 to 1.71), >1-week vision loss (1.17; 1.08 to 1.27), ocular comorbidities (1.18; 1.00 to 1.38), poor presenting VA (1.06 per initial logMAR unit; 1.02 to 1.10) and age >70 (1.13; 1.04 to 1.23). The data were split into training (75%) and validation (25%) and a scoring system was developed and validated. The risk for poor visual outcomes was 8% with a total score of 0, 17% with 1, 29% with 2, 47% with 3, and 71% with 4 or higher. CONCLUSIONS: Independent risk factors were compared for poor visual outcomes after RRD surgery, which included PVR, anti-VEGF injections, vision loss >1 week, ocular comorbidities, presenting VA and older age. The PRO score was developed to provide a scoring system that may be useful in clinical practice.

PURPOSE: We report a patient with CTNNB1-associated vitreoretinopathy. We discuss imaging findings and surgical management. METHODS: Case report. RESULTS: An 18-month-old girl with microcephaly, failure to thrive, developmental delay, and chronic rhinitis presented with bilateral central and peripheral tractional retinal detachments and an anomalous retinal vasculature. She underwent multimodal imaging and genetic testing, and we discuss successful surgical management. CONCLUSION: CTNNB1 mutations can cause a vision-threatening vitreoretinopathy. We recommend CTNNB1 to be considered as part of the workup of patients presenting with familial exudative vitreoretinopathy-like clinical findings, especially if there are systemic manifestations.

PURPOSE: To determine factors associated with loss of good vision (defined as Snellen visual acuity [VA] < 20/40) after surgery among eyes presenting with macula-on primary rhegmatogenous retinal detachment (RRD) with initial VA ≥20/40. METHODS: Multicenter, retrospective, cohort study of eyes undergoing scleral buckle (SB), pars plana vitrectomy (PPV), or combined pars plana vitrectomy/scleral buckle (PPV/SB) for non-complex macula-on RRD with initial VA ≥20/40. RESULTS: Among 646 eyes with macula-on RRDs with initial VA ≥20/40, 106 (16.4%) had VA <20/40 (i.e. lost good vision) at final follow-up. Eyes losing good vision had slightly worse pre-operative logMAR VA (mean 0.15 ± 0.10 [20/28]) compared to eyes that preserved good vision (mean 0.11 ± 0.10 [20/26]) (p = 0.004). RRDs extending greater than 6 clock-hours were more likely to lose good vision than smaller detachments (multivariate OR 4.57 [95% CI 1.44-14.51]; p = 0.0099). Compared to eyes repaired with SB alone, eyes undergoing PPV (multivariate OR 7.22 [95% CI 2.10-24.90]; p = 0.0017) or PPV/SB (multivariate OR 10.74 [95% CI 3.20-36.11]; p = 0.0001) were each more likely to lose good vision. Eyes requiring further RRD-related (multivariate OR 8.64 [95% CI 1.47-50.66]; p < 0.017) and non-RRD related vitreoretinal surgery (multivariate OR 14.35 [95% CI 5.39-38.21]; p < 0.0001) were more likely to lose good vision. CONCLUSION: Among macula-on RRDs, loss of good vision was associated with worse vision on presentation, vitrectomy-based procedures, greater extent of detachment, and lack of single surgery success. Understanding predictors of visual outcome in macula-on RRD repair may guide pre-operative counseling regarding visual prognosis.

AIM: To quantify the areas of burden experienced by patients requiring repeated intravitreal injections (IVI) in the management of exudative retinal diseases. METHODS: The validated Questionnaire to Assess Life Impact of Treatment by Intravitreal Injections survey was administered to patients at four retina clinical practices across four US states. The primary outcome measure was Treatment Burden Score (TBS), a single score assessing overall burden. RESULTS: Of 1416 (n=657 age-related macular degeneration; n=360 diabetic macular oedema/diabetic retinopathy; n=221 retinal vein occlusion; n=178 other/uncertain) patients, 55% were women with an average age of 70 years. Patients most frequently reported receiving IVI every 4-5 weeks (40%). The mean TBS was 16.1±9.2 (range 1-48; scale of 1-54), and the TBS was higher in patients with diabetic macular oedema and/or diabetic retinopathy (DMO/DR) (17.1) compared with those with age-related macular degeneration (15.5) or retinal venous occlusive (15.3) (p=0.028). Though the mean level of discomfort was quite low (1.86) (scale 0-6), 50% of patients reported experiencing side effects more than half of the visits. Patients having received fewer than 5 IVI reported higher mean anxiety levels before (p=0.026), during (p=0.050) and after (p=0.016) treatment compared with patients having received more than 50 IVI. After the procedure, 42% of patients reported restrictions from usual activities due to discomfort. Patients reported a high mean satisfaction rating of 5.46 (scale 0-6) with the care of their diseases. CONCLUSIONS: The mean TBS was moderate and highest among patients with DMO/DR. Patients with more total injections reported lower levels of discomfort and anxiety but higher disruption to daily life. Despite the challenges related to IVI, the overall satisfaction with treatment remained high.

Purpose: This work evaluates the anatomic and functional outcomes of primary rhegmatogenous retinal detachments (RRDs) with preoperative grade B and C proliferative vitreoretinopathy (PVR) vs eyes without PVR. Methods: As a multi-institutional, interventional, retrospective study of all patients undergoing primary RRD surgical procedures from January 1, 2015, through December 31, 2015, this study evaluated the visual acuity (VA) outcomes and single-surgery anatomic success rates (SSAS) of patients with primary grade B and C PVR at the time of RRD repair. Results: A total of 2486 eyes underwent primary RD surgery during the study period, of which 153 eyes (6.2%) had documented preoperative PVR grade B or C. Eyes without PVR had better SSAS compared with eyes with grade B or C PVR (87% vs 83% vs 75%, respectively, P < .0001). Eyes without PVR also had better final mean (SD) logMAR VA (0.35 [0.47]; 20/45 Snellen equivalent) than eyes with PVR of grade B (0.50 [0.56]; 20/63 Snellen equivalent) or grade C (P < .0001). In only eyes with preoperative PVR, there were no significant differences in final VA or SSAS on multivariate analysis based on surgical approach or use of retinectomy or membrane peeling alone in the intraoperative management of PVR. Conclusions: Eyes with primary preoperative grade B and C PVR appear to have significantly worse VA outcomes and lower surgical success rates. Surgical approach and management of PVR membranes did not appear to affect VA or success rates, indicating that preoperative PVR severity may dictate these outcomes.
RESUMO
Purpose: Cryptococcus neoformans is a budding yeast that has a tropism for the central nervous system where it may cause meningitis, which has a high mortality rate. Endophthalmitis is rare and typically occurs in the setting of meningitis and disseminated disease. This report describes an atypical presentation of cryptococcal endophthalmitis and outlines the appropriate workup and management for this disease. Methods: A case report is presented. Results: A 66-year-old man on chemotherapy who presented with blurry vision without any extraocular symptoms was diagnosed with cryptococcal endophthalmitis and found to have underlying bloodstream and central nervous system infection on subsequent workup. He was treated with intravenous and intravitreal antifungals and remained systemically well, although a large subretinal mass lesion remained stable at 2-month follow-up. Conclusions: Cryptococcal endophthalmitis may be the initial presentation of disseminated cryptococcal disease. If vitreous cultures grow Cryptococcus, clinicians should presume that meningitis is present, regardless of symptoms, until proven otherwise.
