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.

Vitreoretinopathy-Associated Pediatric Retinal Detachment Treatment Outcomes: IRIS® Registry (Intelligent Research in Sight) Analysis.

Purpose: To determine the treatment patterns and outcomes of pediatric retinal detachments (RDs) associated with hereditary vitreoretinopathies. Design: Retrospective cohort analysis using IRIS® Registry (Intelligent Research in Sight) database. Participants: Patients < 18 years old with a rhegmatogenous RD and a systemic disorder associated with vitreoretinal degeneration (e.g., Stickler syndrome) or other malformation of the vitreous from 2013-2019. Methods: Cases were identified using International Classification of Diseases, Ninth and Tenth Revisions (ICD-9, ICD-10) diagnostic codes from the IRIS® Registry cohort. Other hereditary vitreoretinopathies that are not encoded by specific ICD code(s) were captured by text search. Nonspecific vitreous abnormality ICD codes were also included. Exclusion criteria included traumatic retinal detachments using ICD codes for ocular trauma and serous or exudative retinal detachment. Surgical procedures were identified using Current Procedural Terminology (CPT) codes for repair of retinal detachment. Baseline demographic information collected included age, gender, race/ethnicity, geographic region of the provider location, and health insurance status. Main Outcome Measures: Main outcomes measured in this study were average time to first surgery, number of eyes presenting with bilateral detachments, and choice of initial surgical procedure. Results: A total of 2115 eyes of 1722 patients were identified (mean age, 10.4 years; 58% male). The median time to first surgery was 7 days (interquartile range, 40 days). One thousand four hundred seven eyes of 1134 patients had ≥ 1 year of follow-up, with 506 eyes (36%) developing a fellow eye RD. Thirty-three percent of patients presenting with bilateral detachments, and 349 eyes had initial RD surgery within 1 year of the index date documented by CPT code. Fellow eye detachment occurred a mean of 32 days after initial presentation. The mean number of surgeries per eye within 1 year was 1.68. Best-corrected visual acuity did not improve from a baseline 20/54 to 20/62. The initial procedure was most commonly complex RD repair (n = 176), followed by scleral buckle (n = 102), pars plana vitrectomy (n = 89), laser (n = 59), cryotherapy (n = 5), and pneumatic retinopexy (n = 5). There were 51 new diagnoses of glaucoma and 37 new diagnoses of aphakia within 1 year after the surgical procedure. Conclusions: IRIS Registry data provide insight into rare pediatric vitreoretinopathy-associated RDs, which have a high rate of reoperation and fellow eye involvement.

Retinal Detachment Prophylaxis for Patients With Stickler Syndrome: A Survey of Pediatric Retinal Specialist Treatment Preferences.

BACKGROUND AND OBJECTIVE: Stickler syndrome is the most common inherited cause of pediatric rhegmatogenous retinal detachment. The purpose of this study was to survey pediatric retinal surgeon preferences for prophylactic treatment of Stickler syndrome patients. STUDY DESIGN: A voluntary, anonymous 27-question survey was developed by RedCap and distributed to the Association of Pediatric Retinal Surgeons. The survey was distributed on March 17, 2021. Results were tabulated on April 12, 2021 in Microsoft Excel. All surveys returned were included. RESULTS: Thirty-four (76% response rate) respondents completed the survey. Twenty-six (76%) reported primarily using prophylactic laser retinopexy, four (12%) preferred use of cryotherapy, and 12% reported using prophylactic scleral buckle. CONCLUSIONS: The majority of the United States. and international pediatric retinal surgeons use laser retinopexy as the primary method of prophylactic treatment. These results may serve as a benchmark for retinal surgeons less familiar with prophylactic treatment approaches. [Ophthalmic Surg Lasers Imaging Retina 2023;54:102-107.].

Risk and Prevention of Retinal Detachments in Patients with Stickler Syndrome.

BACKGROUND AND OBJECTIVE: To report the impact of prophylactic laser retinopexy in the prevention of retinal detachments (RDs) in patients with Stickler syndrome. PATIENTS AND METHODS: This was a retrospective, comparative case series of patients with Stickler syndrome from the year 2000 to 2019. We compared the rate of RDs between individuals who did and did not receive prophylactic laser therapy. In patients with an RD, we compared the rate of RD in the fellow eye with and without prophylactic laser treatment. RESULTS: A total of 95 eyes were identified. Fifty-four percent of the overall population was female. The RD rate was 26.7% among eyes without previous prophylactic laser retinopexy and 4.6% among eyes with previous prophylactic laser retinopexy. A Cox proportional model revealed that laser prophylaxis treatment had a statistically significant effect on the risk of RD or retinal tear during the 25-year survival period from birth (P = .034). Eyes receiving treatment were 70% less likely to experience RD or retinal tear (hazard ratio, 0.297; 95% CI, 0.097 to 0.913). CONCLUSIONS: This study's results suggest a potential role for prophylactic laser retinopexy in the prevention of rhegmatogenous RD among patients with a clinical diagnosis of Stickler syndrome.

COST ANALYSIS OF SCLERAL BUCKLE, PARS PLANA VITRECTOMY, AND PARS PLANA VITRECTOMY WITH SCLERAL BUCKLE FOR RETINAL DETACHMENT REPAIR.

PURPOSE: To compare the cost and utility of scleral buckle (SB), pars plana vitrectomy (PPV), and PPV with SB (PPV/SB) for moderately complex rhegmatogenous retinal detachment repair. METHODS: Cost-utility analysis using data from the Primary Retinal Detachment Outcomes Study. The model estimated costs, lifetime utility, and lifetime cost per quality-adjusted life year for treatment of moderately complex rhegmatogenous retinal detachment with SB, PPV, or PPV/SB. Data from the Centers for Medicare and Medicaid Services were used to calculate costs in hospital and ambulatory surgery center settings. RESULTS: Total costs (2020 US dollars) for repair of a moderately complex rhegmatogenous retinal detachment in hospital (ambulatory surgery center) settings were $5,975 ($3,774) for the SB group, $8,125 ($5,082) for the PPV group, and $7,551 ($4,713) for the PPV/SB group. The estimated lifetime quality-adjusted life years gained were 5.4, 4.7, and 4.7 in the SB, PPV, and PPV/SB groups, respectively. The cost per quality-adjusted life year for hospital and ambulatory surgery center settings was $1,106 a ($699) for the SB group, $1729 ($1,081) for the PPV group, and $1,607 ($1,003) for the PPV/SB group. CONCLUSION: Scleral buckle, PPV, and PPV/SB yielded very favorable cost-utility results for the repair of moderately complex rhegmatogenous retinal detachment, with slightly better results for SB, compared with current willingness to pay standards.

Multiple Genetically Distinct Uveal Melanomas Arise in the Same Eye of Two Patients with Melanosis Oculi.

PURPOSE: To determine whether unilateral multifocal uveal melanomas (UM) in the setting of ocular melanosis (melanosis oculi) represent genetically independent tumors. DESIGN: Clinical case series. METHODS: Two patients with unilateral multifocal UM in the setting of melanosis oculi were included. Tumors were evaluated for gene expression profile (GEP) and next generation sequencing (NGS) for uveal melanoma-associated mutations. Histopathologic analysis of enucleated specimens was also performed when available. RESULTS: Patients were both female, ages 73 and 83 years. In Patient #1, the tumors both exhibited Class 2 GEP but each harbored a unique BAP1 mutation. In Patient #2, one tumor was Class 1 and harbored an SF3B1 mutation, whereas the other tumor was Class 2 and harbored a BAP1 mutation. CONCLUSIONS: Unilateral multifocal UM in the setting of melanosis oculi can arise due to the development of genetically independent primary tumors, which is detectable based on the mutation profile of each tumor. This is the first report of genetically-confirmed independent primary tumors in the setting of unilateral multifocal UM.

EXTERNAL DRAINAGE OF SUBRETINAL FLUID DURING RHEGMATOGENOUS RETINAL DETACHMENT REPAIR.

PURPOSE: To describe the safety and efficacy of rhegmatogenous retinal detachment (RRD) repair with external drainage of subretinal fluid using a 28-gauge External Drainage and Depression device (Vortex Surgical, Chesterfield, MO). METHODS: Retrospective review of patients who underwent primary rhegmatogenous retinal detachment repair with scleral buckle, pars plana vitrectomy, or scleral buckle/pars plana vitrectomy using the drainage device from August 2018 through March 2020, performed by four surgeons at two vitreoretinal practices. RESULTS: Eighty-three eyes of 83 patients were included. At presentation, 28% had proliferative vitreoretinopathy. Surgery included 65% scleral buckle/pars plana vitrectomy, 33% pars plana vitrectomy, and 2% scleral buckle. There were no cases of retinal incarceration and two subretinal hemorrhages at the drainage site (both < 2 DD), 2 cases of recurrent RD with proliferative vitreoretinopathy (1 had proliferative vitreoretinopathy at presentation), and 6 (10%) new epiretinal membranes (3 were mild). There were no other complications. Mean follow-up was 274 days. Single operation success rate for those with ≥ 6-month follow-up was 97% (57/59). CONCLUSION: External drainage of subretinal fluid during rhegmatogenous retinal detachment repair demonstrated a favorable safety profile with a high single operation success rate. Further study of the role of external drainage in rhegmatogenous retinal detachment repair is warranted.

Incidence and Risk of Scleral-Fixated Akreos (AO60) Lens Opacification: A Case Series.

Purpose: Postoperative hydrophilic intraocular lens opacification can lead to decreased vision and may require intraocular lens exchange. This study aims to identify the incidence of scleral-fixated Akreos AO60's (Bausch + Lomb) lens opacification and risk factors for this phenomenon. Methods: This is a retrospective case series of all patients who underwent scleral-fixated Akreos AO60 lens at our institution between January 1, 2015 and December 31, 2019. The following data were recorded: age, sex, medical history, indication for Akreos AO60 implantation, laterality, ocular history, previous ocular surgical procedures, subsequent intraocular surgical procedures after the Akreos implantation, lens opacification, visual significance of opacification, and Akreos explantation. Intraoperative and postoperative complications were recorded. Main outcome measures were the overall incidence of Akreos lens opacification as well as the incidence of these eyes undergoing subsequent intraocular surgery. Results: A total of 262 eyes of 257 patients underwent Akreos lens implantation. Overall, 2% (5 of 262) developed lens opacification. Two patients had Descemet stripping automated endothelial keratoplasty (DSAEK) concurrently with Akreos implantation. One patient underwent subsequent Baerveldt glaucoma implantation and DSAEK. The fourth patient had vitrectomy with sulfur hexafluoride gas followed by DSAEK. This represents a 25% (4 of 16) opacification rate among all patients who underwent DSAEK (P ≤ .01, Fisher exact test). One patient developed opacification after undergoing 2 vitrectomies for retinal detachment in the absence of DSAEK. Conclusions: Akreos lens opacification can be visually significant and may occur after a retinal or corneal procedure that involves the use of intraocular gas or air.

Traumatic Retinal Detachment in Patients with Self-Injurious Behavior: An International Multicenter Study.

PURPOSE: To describe the clinical characteristics, surgical outcomes, and management recommendations in patients with traumatic rhegmatogenous retinal detachment (RRD) resulting from self-injurious behavior (SIB). DESIGN: International, multicenter, retrospective, interventional case series. PARTICIPANTS: Patients with SIB from 23 centers with RRD in at least 1 eye. METHODS: Clinical histories, preoperative assessment, surgical details, postoperative management, behavioral intervention, and follow-up examination findings were reviewed. MAIN OUTCOME MEASURES: The rate of single-surgery anatomic success (SSAS) was the primary outcome. Other outcomes included new RRD in formerly attached eyes, final retinal reattachment, and final visual acuity. RESULTS: One hundred seven eyes with RRDs were included from 78 patients. Fifty-four percent of patients had bilateral RRD or phthisis bulbi in the fellow eye at final follow-up. The most common systemic diagnoses were autism spectrum disorder (35.9%) and trisomy 21 (21.8%) and the most common behavior was face hitting (74.4%). The average follow-up time was 3.3 ± 2.8 years, and surgical outcomes for operable eyes were restricted to patients with at least 3 months of follow-up (81 eyes). Primary initial surgeries were vitrectomy alone (33.3%), primary scleral buckle (SB; 26.9%), and vitrectomy with SB (39.7%), and 5 prophylactic SBs were placed. Twenty-three eyes (21.5%) with RRDs were inoperable. The SSAS was 23.1% without tamponade (37.2% if including silicone oil), and final reattachment was attained in 80% (36.3% without silicone oil tamponade). Funnel-configured RRD (P = 0.006) and the presence of grade C proliferative vitreoretinopathy (P = 0.002) correlated with re-detachment. The use of an SB predicted the final attachment rate during the initial surgery (P = 0.005) or at any surgery (P = 0.008. These associations held if restricting to 64 patients with ≥12 months followup. Anatomic reattachment correlated with better visual acuity (P < 0.001). CONCLUSIONS: RRD resulting from SIB poses therapeutic challenges because of limited patient cooperation, bilateral involvement, chronicity, and ongoing trauma in vulnerable and neglected patients. The surgical success rates were some of the lowest in the modern retinal detachment literature. The use of an SB may result in better outcomes, and visual function can be restored in some patients.

Adams-Oliver syndrome: a case of bilateral progressive ischemic maculopathy.

Adams-Oliver syndrome (AOS) is a congenital condition characterized by aplasia cutis congenita of the scalp and transverse limb defects. Other clinical features reported in association with AOS include cardiac malformations, cutis marmorata telangiectatica congenita, prenatal complications, and ophthalmic abnormalities. Reported ophthalmic manifestations range from Peters anomaly-like findings and cataract formation to incomplete or abnormal retinal vasculature, optic nerve hypoplasia, and rod dystrophy. We report the novel case of a 3-month-old boy with AOS type 2 who was found to have bilateral progressive macular ischemia.

Analysis of Emergent Nonhospital-Based Retina Consultation Requests in an Academic Nonhospital-Associated Retina Practice.

PURPOSE: To evaluate the outcomes of after-hour encounters concerning patients referred by eye physicians to on-call retina services for emergent evaluation not seen in or referred by an emergency department. DESIGN: Retrospective study. PARTICIPANTS: Patients seeking treatment at 3 private practice institutions over a 2-year period between 2017 and 2018. METHODS: A retrospective chart review was conducted comprising all patients who sought treatment emergently and after clinic hours from 3 academic nonhospital-associated retina-only private practice institutions over a 2-year period. MAIN OUTCOME MEASURES: Patient presenting symptoms, diagnosis given at time of after-hours appointment, duration of symptoms, source of after-hours consultation (patient or provider), procedure performed at appointment, and appointments that led to surgery. RESULTS: Nine hundred eighty-seven charts were reviewed. Provider referrals accounted for 49.13% (n = 485) and patient-derived referrals accounted for 50% (n = 493) of appointments. New patients accounted for 27.6% (n = 146) of patient-derived and 85.2% (n = 413) of provider-derived referrals. The most common presenting symptoms were flashes and floaters (42.5%; n = 420), decrease in visual acuity (32.1%; n = 317), generalized eye pain (7.4%; n = 73), visual field disturbance (4.3%; n = 42), and postoperative ocular pain (3.4%; n = 34). An in-office procedure was performed at the time of examination in 18% of encounters (n = 178), with most of these being laser retinopexy. Surgery was performed within 24 hours in 18% (n = 180), within 48 hours in 20.6% (n = 203), within 72 hours in 21.7% (n = 214), and within 96 hours in 22.6% (n = 223) of the appointment. When combined with procedures, 36.2% (n = 358) of encounters led to urgent intervention within 24 hours. If a provider called about an existing patient, 37.5% of these appointments (n = 27) led to surgery versus 12.8% (n = 49) if an existing patient self-referred. If a provider called about a new patient, 31.7% of these appointments (n = 131) led to surgery versus 10% (n = 14) if a new patient self-referred. CONCLUSIONS: At these 3 private practice retinal specialty clinics, 41% of after-hours appointment requests resulted in an intervention within 96 hours, and 36% of these patients underwent an intervention within 24 hours.

Complications of vitreoretinal surgery.

PURPOSE OF REVIEW: The present article reviews the most common and most serious vision-threatening and life-threatening complications of vitreoretinal surgery. RECENT FINDINGS: Serious complications after vitreroretinal surgery are rare. Endophthalmitis for example has recently been estimated to occur in 0.08% of small gague vitrectomy. Other complications such as cataract are almost unavoidable, becoming visually significant in up to 80% of patients. The introduction of smaller gauge vitrectomy systems has reduced surgical times, conjunctival scarring and inflammation, and the rate of some complications such as retinal tears. Ocular venous air embolism is an exceedingly rare complication that is potentially life threating and therefore important for all vitreoretinal surgeons to be aware of. SUMMARY: Though vitreoretinal surgery is well tolerated and effective, it is inevitable that all surgeons will experience complications and are therefore best served by understanding the potential complications, strategies to reduce the likelihood of them occurring, and ways to address them when they do happen.

The use of bevacizumab in pediatric retinal and choroidal disease: A review.

The use of intravitreal bevacizumab in pediatric retinal and uveitic disease has become more widespread over the past decade. This article serves to outline the rationale underlying the use of intravitreal bevacizumab, and which disease entities it should be appropriately thought of as a primary or solo therapy, as opposed to an adjuvant one. Also presented is the relevant literature regarding each of these retinopathies.

Endophthalmitis caused by Enterococcus faecalis: clinical features, antibiotic sensitivities, and outcomes.

PURPOSE: To report the clinical features, antibiotic sensitivities, and visual acuity outcomes of endophthalmitis caused by Enterococcus faecalis. STUDY DESIGN: Retrospective, observational case series. METHODS: A consecutive case series of patients with culture-positive endophthalmitis caused by E. faecalis between January 1, 2002, and December 31, 2012, at an academic referral center. RESULTS: Of 14 patients identified, clinical settings included bleb association (n = 8), occurrence after cataract surgery (n = 4), and occurrence after penetrating keratoplasty (n = 2). All isolates were vancomycin sensitive. When comparing isolates in the current study with isolates from 1990 through 2001, the minimal inhibitory concentration required to inhibit 90% of isolates increased for ciprofloxacin (4 µg/mL from 1 µg/mL), erythromycin (256 µg/mL from 4 µg/mL), and penicillin (8 µg/mL from 4 µg/mL), indicating higher levels of resistance. The minimal inhibitory concentration required to inhibit 90% of isolates remained the same for vancomycin (2 µg/mL) and linezolid (2 µg/mL). Presenting visual acuity ranged from hand movements to no light perception. Initial treatment strategies were vitreous tap and intravitreal antibiotic injection (n = 12) and pars plana vitrectomy with intravitreal antibiotic injection (n = 2). Visual acuity outcomes were 20/400 or worse in 13 (93%) of 14 patients. CONCLUSIONS: Although all isolates were sensitive to vancomycin and linezolid, higher minimal inhibitory concentration required to inhibit 90% of isolates in the current study, compared with isolates from 1990 through 2001, occurred with ciprofloxacin, erythromycin, and penicillin. Despite prompt treatment, most patients had poor outcomes.
