BILATERAL EYE PATCHING MAY IMPROVE CLINICAL OUTCOMES FOR ACUTE PRIMARY RHEGMATOGENOUS RETINAL DETACHMENT.

PURPOSE: Evaluate preoperative bilateral eye patching (BEP) on subretinal fluid and vision in acute primary rhegmatogenous retinal detachments (RRDs). METHODS: Retrospective nonrandomized interventional study of 335 patients with RRD undergoing BEP until surgery (BEP cohort) and separated by the percentage of full-time compliance: high (≥90%), medium (>90% but ≥50%), and low (<50%). Those declining BEP were included (control). All underwent surgery and were followed for ≥3 months. Imaging was obtained immediately before surgery. Best-corrected visual acuity was measured at the longest follow-up and immediately before surgery. SRF and foveal status immediately before surgery were analyzed. RESULTS: Two hundred and forty and 95 patients were in BEP and control cohorts, respectively. Thirty patients presented immediately before surgery for analysis. High (64%) and medium (35%) compliance showed significantly greater ( P < 0.01) SRF reduction compared with low (4%) and control (3%). Mac-off RRD showed significantly greater ( P < 0.01) foveal reattachment with high (29%) and medium (8%) compliance compared with low (2%) and control (1%). Mac-on RRD demonstrated no significant differences ( P ≥ 0.51) in final best-corrected visual acuity among high (0 logarithm of the minimum angle of resolution [logMAR] [median], 20/20 Snellen), medium (0.10 logMAR, 20/25 Snellen), low (0.10 logMAR), and control cohorts (0.10 logMAR). Mac-off RRD demonstrated significantly better final best-corrected visual acuity with high compliance (0.30 logMAR, 20/40 Snellen) compared with low (0.40 logMAR, 20/50 Snellen; P = 0.04) and control (0.60 logMAR, 20/80 Snellen; P = 0.02). CONCLUSION: Preoperative BEP can stabilize or improve subretinal fluid in acute primary RRD. Patients with BEP >50% of the time experienced the greatest benefits.

PROPHYLACTIC TREATMENT OF LATTICE DEGENERATION IN FELLOW EYES AFTER REPAIR OF UNCOMPLICATED PRIMARY RHEGMATOGENOUS RETINAL DETACHMENT.

PURPOSE: To evaluate prophylactic treatment (PTx) of lattice degeneration (LD) on retinal tear (RT) and rhegmatogenous retinal detachment (RRD) risk in fellow eyes of patients after primary RRD repair in the first eye. METHODS: This was a consecutive case series with cohort control involving patients with RRD repair from January 1, 2013, through December 31, 2017. Patients received PTx (PTx cohort) or no PTx (No-PTx cohort) in fellow eye with 5-year follow-up. Primary outcome measure was proportion with new fellow eye RT/RRD. Secondary outcomes included logarithm of minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA) and status of myopia, posterior vitreous detachment, and pseudophakia. RESULTS: Four hundred ninety-eight patients were divided into 146 and 352 in PTx and No-PTx cohorts, respectively. PTx cohort developed significantly ( P < 0.05) fewer RT/RRD (17%) than No-PTx cohort (41%). PTx significantly ( P < 0.05) lowered RT/RRD irrespective of posterior vitreous detachment and myopia status. PTx patients undergoing phacoemulsification demonstrated significantly ( P < 0.05) less RT/RRD (22%) than No-PTx cohort (31%). There was no significant ( P = 0.96) final BCVA difference between PTx (median = 0 logMAR) and No-PTx (median = 0 logMAR) cohorts. CONCLUSION: PTx of asymptomatic fellow eye LD reduced RT/RRD risk.

Clinical Factors and Outcomes of Acute-Onset Endophthalmitis Following Small-Gauge Pars Plana Vitrectomy Surgery.

BACKGROUND AND OBJECTIVES: Describe risk factors, findings, and outcomes of acute endophthalmitis (AE) following small-gauge pars plana vitrectomy (PPV). PATIENTS AND METHODS: This was a retrospective single-center, nonrandomized study of post-PPV AE patients from 2013 to 2021. All received vitreous biopsy before treatment. Patients were divided into cohorts: 1) PPV within 3 days of diagnosis (Urgent-PPV), and 2) no urgent PPV (Other-treatment [Tx]). Main outcome was best-corrected visual acuity (BCVA) at 6 months. RESULTS: Twenty-one patients were analyzed. Epiretinal membrane was the most common indication for PPV (48%). Incidence was 0.074%. Culture-positive rate was 57%. For final BCVA, there was no significant (P = 0.85) difference between Urgent-PPV (median = 0.40 logMAR) and Other Tx cohorts (median = 0.35 logMAR). Sclerotomy wounds were not sutured in 71% of patients. Approximately 24% and 38% of patients analyzed had either no tamponade or partial tamponade, respectively. CONCLUSION: Tamponade agents and sclerotomy suturing may be important factors when evaluating post-small-gauge PPV-associated AE. Further studies are necessary for clarification.

Evaluation of Outcomes of Acute Cataract Surgery-Related Endophthalmitis Using a Novel Management Algorithm Based on Presenting Risk Factors.

PURPOSE: Develop treatment algorithm for acute endophthalmitis (AE) following cataract surgery. METHODS: Retrospective single-center, non-randomized interventional study involving patients with AE divided into cohorts according to our novel scoring system, the Acute Cataract surgery-related Endophthalmitis Severity (ACES) score. Total score ≥3 points indicated need for urgent pars plana vitrectomy (PPV; within 24 hours), whereas <3 points indicated urgent PPV was unnecessary. Patients were retrospectively evaluated for visual outcomes based on whether their clinical course followed with or deviated from ACES score recommendations. Main outcome was best-corrected visual acuity (BCVA) at 6-month or longer after treatment. RESULTS: Total of 150 patients were analyzed. Patients whose clinical course followed the ACES score recommendation for immediate surgery had significantly (P < 0.01) better final BCVA (median = 0.18 logMAR, 20/30 Snellen) compared to those that deviated (median = 0.70 logMAR, 20/100 Snellen). For those where the ACES score deemed urgent PPV was unnecessary, no significant (P = 0.19) difference was observed between patients that followed with (median = 0.18 logMAR, 20/30 Snellen) and those that deviated from (median = 0.10 logMAR, 20/25 Snellen) recommendation. CONCLUSIONS: The ACES score may potentially provide critical and updated management guidance at presentation for when to recommend urgent PPV for patients suffering from post-cataract surgery AE.

CLINICAL OUTCOMES OF ACUTE ENDOPHTHALMITIS AFTER INTRAVITREAL DELIVERY OF VASCULAR ENDOTHELIAL GROWTH FACTOR INHIBITORS VERSUS STEROIDS.

PURPOSE: To compare patients with acute endophthalmitis after intravitreal injection of vascular endothelial growth factor (VEGF) inhibitors vs. steroids. METHODS: Retrospective single-center, nonrandomized interventional study from 2013 to 2021.Patients underwent vitreous biopsy before initiating treatment and were divided into the following cohorts: (1) anti-VEGF managed medically (T&I-anti-VEGF), (2) anti-VEGF managed by immediate pars plana vitrectomy (PPV-anti-VEGF), and (3) steroid therapy and managed medically or by pars plana vitrectomy (steroid). RESULTS: A total of 141 patients were analyzed. The steroid cohort demonstrated significantly worse presenting (median = 2.80 logarithm of the minimum angle of resolution [logMAR]; P ≤ 0.01) and final (median = 2.30 logMAR) best-corrected visual acuity compared with T&I-anti-VEGF (presenting: median = 2.00 logMAR; final: median = 0.40 logMAR) and pars plana vitrectomy-anti-VEGF cohorts (presenting: median = 2.30 logMAR; final: median = 0.48 logMAR). There was no significant ( P = 0.33) difference in the final best-corrected visual acuity between T&I-anti-VEGF and pars plana vitrectomy-anti-VEGF cohorts. There were no significant ( P ≥ 0.63) differences among cohorts in best-corrected visual acuity before acute endophthalmitis diagnosis (T&I-anti-VEGF: median = 0.40 logMAR; pars plana vitrectomy-anti-VEGF: median = 0.40 logMAR; steroid: median = 0.44 logMAR). Microbial cultures revealed similar profiles for all cohorts. CONCLUSION: Acute endophthalmitis after intravitreal injection steroid therapy had worse outcomes compared with anti-VEGF therapy.
