IMPACT OF FOVEAL STATUS AND TIMING OF SURGERY ON VISUAL OUTCOME IN RHEGMATOGENOUS RETINAL DETACHMENT.

PURPOSE: To investigate the impact of surgical timing on visual acuity outcomes in retinal detachments based on the preoperative foveal status. METHODS: A retrospective multicenter cohort study was conducted. Cases were stratified into fovea-on, fovea-split, and fovea-off groups. Days to surgery was defined as the time between the preoperative examination and surgery. The main outcome measure was the final postoperative visual acuity. RESULTS: 1,675 cases were studied. More than 80% of fovea-on/fovea-split and fovea-off cases had surgery within 1 and 3 days, respectively. The mean final postoperative visual acuity did not differ significantly between the fovea-on and fovea-split groups (Snellen equivalent [SE] 20/33 ± 20/49 and 20/32 ± 20/39, P = 1.000) and did not change significantly based on days to surgery in either group. The mean final postoperative visual acuity was lowest in the fovea-off group (Snellen equivalent = 20/56 ± 20/76, P < 0.001) and was significantly lower in cases where surgery was performed after two or more days when compared with cases performed within 1 day (Snellen equivalent 20/74 ± 20/89 vs. 20/46 ± 20/63, P < 0.001). CONCLUSION: Fovea-on and fovea-split retinal detachments demonstrated comparable visual outcomes. Fovea-off RDs demonstrated worse visual outcomes, which declined further when surgery was delayed by two or more days.

Role of physician extenders: more regulation is necessary before full integration into practice.

PURPOSE OF REVIEW: To discuss the drawbacks and propose recommendations for integrating physician extenders in ophthalmologic practice. RECENT FINDINGS: In this article, the role of utilizing physician extenders in ophthalmology is discussed. A role for physician extenders has been suggested as more and more patients will require ophthalmologic care. SUMMARY: Guidance is needed on how to best integrate physician extenders into eye care. However, quality of care is of the highest importance, and unless there is reliable and consistent training of extenders, using physician extenders to administer invasive procedures (e.g., intravitreal injection) should be avoided due to safety concerns.

Workup following retinal artery occlusion-experience from an outpatient retina clinic and the delay in workup.

PURPOSE: Acute retinal artery occlusion (RAO) is an urgent ophthalmic condition often indicative of future ischemic pathology. Patients diagnosed at an outpatient retina clinic must present to an emergency department (ED) or primary care clinic to obtain a systemic workup. We review the overall compliance and suspected delay in completing the required testing. DESIGN: Retrospective cohort study METHODS: Patients presenting with a symptomatic RAO from June 2009 to January 2019 at a vitreoretinal practice (The Retina Institute, St. Louis, MO) were included. Documentation of carotid vasculature and echocardiographic imaging was requested from the patient's primary care physician (PCP), cardiologist, or neurologist. Time to workup (TTW) from RAO diagnosis to receiving appropriate workup and site of workup (ED vs. outpatient setting) were recorded. RESULTS: One hundred forty-seven patients were included. A total of 132 (89.8%) patients were documented as having completed at least one type of cardiovascular or carotid imaging. Seventy-seven patients (52.3%) were documented to have completed both carotid and echocardiographic imaging. Following RAO diagnosis, 97 (66.0%) patients were referred to an outpatient facility while 35 (23.8%) were evaluated at an ED. Mean TTW through an ED setting vs. outpatient was 2.20 days (1.10 STDM, range 0-29) vs.13.6 days (2.23 STDM, range 0-149) respectively (p=0.003). CONCLUSION: Our study gives objective data to the delay suspected in referring patients with acute symptomatic RAO for outpatient workup. We recommend all outpatient ophthalmology and retina practices establish a relationship with a comprehensive or primary stroke center to facilitate urgent testing through an emergency department.

Primary Retinal Detachment Outcomes Study: Pseudophakic Retinal Detachment Outcomes: Primary Retinal Detachment Outcomes Study Report Number 3.

PURPOSE: This study evaluates outcomes of comparable pseudophakic rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV) or PPV with scleral buckle (PPV-SB). DESIGN: Multicenter, retrospective, interventional cohort study. PARTICIPANTS: Data were gathered from patients from multiple retina practices in the United States with RRD in 2015. METHODS: A large detailed database was generated. Pseudophakic patients with RRD managed with PPV or PPV-SB were analyzed for anatomic and visual outcomes. Eyes with proliferative vitreoretinopathy, giant retinal tears, previous invasive glaucoma surgery, and ≤90 days of follow-up were excluded from outcomes analysis. Single surgery anatomic success (SSAS) was defined as retinal attachment without ongoing tamponade and with no other RRD surgery within 90 days. MAIN OUTCOME MEASURES: Single surgery anatomic success and final Snellen visual acuity (VA). RESULTS: A total of 1158 of 2620 eyes (44%) with primary RRD were pseudophakic. A total of 1018 eyes had greater than 90 days of follow-up. Eyes with proliferative vitreoretinopathy, previous glaucoma surgery, and giant retinal tears were excluded, leaving 893 pseudophakic eyes eligible for outcome analysis. A total of 461 (52%) were right eyes. A total of 606 patients (67%) were male, with a mean age of 65±11 years. Pars plana vitrectomy and PPV-SB as the first procedure were performed on 684 eyes (77%) and 209 eyes (23%), respectively. The mean follow-up was 388±161 days, and overall SSAS was achieved in 770 eyes (86%). Single surgery anatomic success was 84% (577/684) for PPV and 92% (193/209) for PPV-SB. The difference in SSAS between types of treatment was significant (P = 0.009). In eyes with macula-on RRD, SSAS was 88% in eyes treated with PPV and 100% in eyes treated with PPV-SB (P = 0.0088). In eyes with macula-off RRD, SSAS was 81% in eyes treated with PPV and 89% in eyes treated with PPV-SB (P = 0.029). Single surgery anatomic success was greater for PPV-SB than PPV for inferior (96% vs. 82%) and superior (90% vs. 82%) detachments. Mean final VA was similar for PPV (20/47) and PPV-SB (20/46; P = 0.805). CONCLUSIONS: In pseudophakic RRDs, SSAS was better in patients treated with PPV-SB compared with PPV alone, whereas visual outcomes were similar for both groups.

Primary Retinal Detachment Outcomes Study Report Number 2: Phakic Retinal Detachment Outcomes.

PURPOSE: Anatomically similar rhegmatogenous retinal detachments (RRDs) can be treated with scleral buckle (SB), pars plana vitrectomy (PPV), or SB combined with PPV (PPV/SB). This study compares moderately complex phakic primary RRD treated with SB, PPV, or PPV/SB to review anatomic and visual outcomes. DESIGN: Multicenter, retrospective, interventional cohort study. PARTICIPANTS: Data were gathered on all patients from multiple retina practices in the United States with RRD in 2015 and >90 days of follow-up. The cohort of phakic patients with moderately complex RRD was analyzed. METHODS: A large and detailed database was generated. Eyes with findings that would bias toward PPV (vitreous hemorrhage, dense cataract, proliferative vitreoretinopathy, giant retinal tear, among others) were excluded. Age <40 years (bias toward SB) was excluded. Comparable cases of moderately complex RRD were then chosen naive to surgeon, surgery, and outcome for subgroup analysis. MAIN OUTCOME MEASURES: Single surgery anatomic success (SSAS), defined as retinal attachment with no other RRD surgery within 90 days, is the main outcome measure. Final visual acuity is the secondary outcome measure. Pearson's chi-square and analysis of variance were used to test treatment effect of surgery type on SSAS and vision. RESULTS: Single surgery anatomic success was noted in 155 of 169 SB cases (91.7%), 207 of 249 PPV cases (83.1%), and 271 of 297 PPV/SB cases (91.2%). Scleral buckle and PPV/SB were superior to PPV for SSAS (P = 0.0041). For macula-on or split cases, SB had significantly better visual outcomes than PPV or PPV/SB even after controlling for cataract (cases with minimal cataract at final follow-up or after cataract surgery) (P < 0.001). CONCLUSIONS: For phakic moderately complex primary RRDs in this study of PPV versus SB versus PPV/SB, SB had the best visual outcomes, and PPV had the worst SSAS outcomes.

WIDE-FIELD INFRARED IMAGING: A Descriptive Review of Characteristics of Retinoschisis, Retinal Detachment, and Schisis Detachments.

PURPOSE: Retinoschisis and retinal detachments are primarily differentiated based on characteristic examination findings. In diagnostically challenging cases, noncontact wide-field infrared imaging can help diagnosis and visualize the extent/margins of retinoschisis, retinal detachment, or combined schisis detachments by comparing reflectivity patterns. METHODS: This is a retrospective, observational, descriptive case series of 14 eyes of 14 nonconsecutive patients, ranging from 28 to 89 years old (mean 61), diagnosed with retinoschisis, retinal detachment, or schisis detachment from May 5, 2014 to March 4, 2015. Patients with secondary retinoschisis and/or retinal detachment from other causes were not included in the study. Heidelberg Wide-Field Module lens and Heidelberg Spectralis HRA+OCT machine (Heidelberg Engineering, Heidelberg, Germany) were used to obtain noncontact, wide-field infrared images on each study eye. RESULTS: Seven eyes with retinal detachments, four with retinoschises, and three with schisis detachments were imaged using this novel wide-field infrared technique. Retinoschisis appears light and translucent with prominent vasculature, retinal detachments appear dark and opaque, and combined retinoschisis/retinal detachment exhibit mixed reflectivity patterns. CONCLUSION: Wide-field infrared imaging provides a quick, noncontact, noninvasive method to accurately diagnose and to monitor for progression of retinoschisis, retinal detachment, or combined schisis detachments.

Laser therapy versus observation for symptomatic retinal artery macroaneurysms.

PURPOSE: The optimal management approach to retinal arterial macroaneurysms (RAM) is unknown. This paper compares long-term outcomes in RAM treated with laser therapy versus observation. METHODS: This is an IRB-approved retrospective study of patients with symptomatic RAM. Charts of patients with a diagnosis of RAM causing symptomatic visual loss were reviewed. Patients with less than 6 months follow up, other confounding diagnoses, or additional therapy beyond thermal laser were excluded. Statistical analysis was done using χ(2) or Student's t test as appropriate. RESULTS: Forty-eight patients with RAM were identified and 27 were included in the study (13 treated, 14 observed). Mean visual acuity in the observation group improved from 20/120 to 20/96 (p = 0.53) compared to 20/280 to 20/54 (p = 0.0003) in the treated group. Subgroup analysis showed that visual acuity in primarily hemorrhagic lesions treated with laser therapy improved by 1.21 logMAR compared to a loss of 0.11 logMAR (p = 0.002) in those that were observed. In primarily exudative lesions, both treated and observed lesions showed an improvement of 0.32 logMAR. No patients in the treatment group had a final visual acuity below 20/200 compared to four in the observation group. CONCLUSION: Treatment with direct laser photocoagulation was associated in this study with greater improvement in visual acuity and may decrease the risk of severe visual loss especially in primarily hemorrhagic RAM lesions. Compared to observation alone.

Peripapillary serous detachment in multiple evanescent white dot syndrome.

BACKGROUND: To report the presence of transient peripapillary serous detachments in multiple evanescent white dot syndrome. METHODS: Retrospective case series. RESULTS: Four eyes of four patients diagnosed with multiple evanescent white dot syndrome presented with peripapillary serous detachments. Diagnosis was based on clinical presentation, fundus findings, and angiographic findings. All 4 were female with age ranges between 24 and 40 years and presented with photopsias, an enlarged scotoma contiguous with the blind spot, and chorioretinal white dots in the posterior pole with characteristic angiographic features. All of the serous detachments resolved or were greatly reduced concomitantly with the resolution of the patient's other clinical symptoms and fundus findings. CONCLUSION: The authors report peripapillary serous detachments as a previously unreported manifestation of multiple evanescent white dot syndrome. These seem to be self limited with concurrent resolution with the rest of the patient's symptoms.

Paraproteinemic maculopathy.

PURPOSE: Paraproteinemia relates to monoclonal gammopathy-producing pathologic antibodies with serous macular detachment being an uncommon ocular manifestation. We ascertained the clinical course of maculopathy in paraproteinemia and investigated the effect of various therapeutic methods on the resolution of subretinal deposits. DESIGN: Multicenter, retrospective, observational case series. PARTICIPANTS: The records of patients with paraproteinemia with optical coherence tomography (OCT) documentation of serous macular detachment were reviewed. METHODS: Data collection included coexisting morbidity, rheology data (immunoglobulin level, hematocrit, and blood viscosity), clinical examination results, and OCT findings. MAIN OUTCOME MEASURES: Best-corrected visual acuity (BCVA), height and basal area of the serous macular detachment, and systemic versus local therapies. RESULTS: A total of 33 cases were collected: 10 new and 23 previously reported in the literature. Diabetes was present in 7 patients, systemic hypertension in 9 patients, and anemia in 18. Mean initial immunoglobulin level was 6497 mg/dl, and mean serum viscosity was 5.5 centipoise (cP). Mean logarithm of the minimum angle of resolution initial vs. final BCVA was 0.55 (Snellen equivalent, 20/71) vs. 0.45 (20/56) in the right eye and 0.38 (20/48) vs. 0.50 (20/63) in the left eye. After mean follow-up of 7 months (range, 0-51 months). Systemic therapies included plasmapheresis (18), chemotherapy (30), blood transfusions (2), transplantation of progenitor hematopoietic cells (2), and oral rituximab (10). Immunoglobulin levels normalized in 8 patients and were unchanged in 1 after plasmapheresis, chemotherapy, or both. Ocular therapy in 8 patients included vitrectomy (1), laser photocoagulation (4), intravitreal bevacizumab (5), intravitreal triamcinolone (2), intravitreal dexamethasone implant (1), intravitreal rituximab (1), and sub-Tenon corticosteroid (1). The maculopathy resolved partially or completely in 17 patients and worsened or remained unchanged in 14 patients over median follow-up of 7 months. Maculopathy was unilateral in 9 cases and occurred at a lower initial immunoglobulin level in diabetics. There was a positive correlation between area of the detachment and serum viscosity. CONCLUSIONS: Paraproteinemic maculopathy can be unilateral. Decreasing the blood immunoglobulin level is the primary goal of therapy for paraproteinemic maculopathy, and this can be achieved by a systemic route. Coexisting diabetes facilitates leakage of immunoglobulins at lower levels than in nondiabetics.

Presbyopia-correcting intraocular lenses and corneal refractive procedures: a review for retinal surgeons.

PURPOSE: To review the specific challenges and pitfalls that vitreoretinal surgeons may face when operating on eyes with presbyopia-correcting intraocular lenses or previous corneal refractive surgery. In addition, this review aims to familiarize vitreoretinal surgeons with specifications of currently available Food and Drug Administration-approved presbyopia-correcting intraocular lenses. METHODS: Review of current literature performed with PubMed for search terms "presbyopia," "correction," "IOL," "vitreoretinal," "challenges," and "surgical" both singly and in combination as well as closely related terms. RESULTS AND CONCLUSION: Specific intraoperative issues with presbyopia-correcting intraocular lenses that may be encountered include peripheral visualization, condensation, lens material issues particularly with silicone oil, decentration, Z-syndrome, and foveal image displacement. Every patient undergoing retinal surgery should also be asked about previous laser-assisted in situ keratomileusis/photorefractive keratectomy because those eyes require special attention to surface hydration and care to avoid epithelial removal if possible. Intracorneal ring segments and corneal inlays can cause effects similar to those of a small pupil. However, these can be managed with thorough preoperative evaluation and various intraoperative maneuvers. In addition, retinal physicians should be aware that macular disorders, such as age-related macular degeneration, may be exacerbated by potential loss of contrast sensitivity.

Macular Findings of Patients on Pentosan Polysulfate Sodium.

INTRODUCTION: In 2018, a unique maculopathy associated with chronic pentosan polysulfate sodium (PPS) use for the treatment of interstitial cystitis (IC) was described, where the authors detailed macular retinal pigment epithelial abnormalities in six patients. In this paper, a retrospective study of a larger patient pool at one large tertiary retina practice was undertaken to evaluate patients taking PPS and their macular findings. MATERIALS AND METHODS: A retrospective chart review was performed on all patients presenting to a single large retina practice between 2011 and 2019. Patient's macular diagnosis, findings, optical coherence tomography scans, and macular auto-fluorescent scans were assessed. This project was Institutional Review Board (IRB) approved by the St Luke's Hospital IRB board (St Louis, MO, USA). RESULTS: Fifty-five patients were identified as taking PPS for IC. Fifty-three patients were found to have a diagnosis consistent with changes attributable to known macular diseases to include macular degeneration and pattern dystrophies. Two (4%) of fifty-five patients had macular findings suggestive of PPS toxicity. The first was a 58-year-old female with subtle retinal pigment epithelium (RPE) deposits on optical coherence tomography that exhibited hyper-autofluorescence. The second was a 72-year-old female with 14 years of PPS use who exhibited RPE excrescences and parafoveal areas of atrophy. CONCLUSIONS: Pentosan polysulfate sodium may be the cause of macular findings in a small percentage of patients referred to a tertiary retina practice. Although causation of macular changes with PPS use has yet to be elucidated, clinicians should be aware of this possibility when assessing patients with atypical macular findings. Future longitudinal studies are necessary to evaluate a definitive relationship. This paper should remind all clinicians of the importance of a throughout review of the patient's medication list as novel toxicities may become apparent years after initial FDA trials. The strength of this study is the larger patient population compared to earlier studies, and the main weaknesses include the retrospective nature of the study, lack of family and genetic testing, and lack of multimodal imaging for all patients.

Timing of Delayed Retinal Pathology in Patients Presenting with Acute Posterior Vitreous Detachment in the IRIS® Registry (Intelligent Research in Sight).

OBJECTIVE: To determine the timing of delayed retinal pathology in eyes presenting with acute posterior vitreous detachment (PVD). DESIGN: Retrospective database study. SUBJECTS: Patients in the Intelligent Research in Sight (IRIS) registry found to have acute PVD based on the International Classification of Diseases, Ninth and Tenth Revision, codes were followed. METHODS: Patients coded to have a PVD from 2013 to 2018 along with common procedural technology coding of extended ophthalmoscopy were included. Ocular baseline characteristics included visual acuity, lens status, presence or absence of vitreous hemorrhage, myopia, lattice degeneration, and subspecialty training of the treating physician. MAIN OUTCOME MEASURES: Timing (days) to delayed retinal break or detachment RESULTS: A total of 434 046 eyes met inclusion/exclusion criteria, and 10 518 eyes (2.42%) presented with a delayed retinal break or detachment after initial PVD. The median time to retinal break and detachment after initial PVD was 42 (range, 1-365) days and 51 (range, 1-365) days, respectively. Eyes with vitreous hemorrhage (hazard ratio [HR], 9.30; 95% confidence interval [CI], 8.50-10.2), history of retinal break/retinal detachment in the fellow eye (HR, 3.91; 95% CI, 3.64-4.20), lattice degeneration (HR, 2.61; 95% CI, 2.35-2.90), and myopia (HR, 1.42; 95% CI, 1.33-1.53) were found to be at a higher risk of developing delayed break or detachment. CONCLUSIONS: Follow-up examination after initial PVD is necessary to diagnose delayed or missed retinal pathology. In eyes with no initial pathology, providers should consider repeat examination at least once within 6 weeks, and sooner for eyes with higher-risk features.

Techniques, rationale, and outcomes of internal limiting membrane peeling.

BACKGROUND: The internal limiting membrane represents the structural interface between the retina and the vitreous and has been postulated to serve several essential functions. Recently, internal limiting membrane peeling has been used in the treatment of a variety of retinal disorders. We review the history, techniques, rationale, and outcomes of internal limiting membrane peeling. METHODS: A review of the literature. RESULTS: Internal limiting membrane peeling has been used to successfully treat a variety of retinal disorders including macular hole, epiretinal membrane, diabetic macular edema, retinal vein occlusion, and others. CONCLUSION: Internal limiting membrane peeling may serve as an important component in the armamentarium of retinal surgery.

Vitrectomy versus Combined Vitrectomy and Scleral Buckle for Repair of Primary Rhegmatogenous Retinal Detachment with Vitreous Hemorrhage.

PURPOSE: To compare pars plana vitrectomy (PPV) with combined PPV and scleral buckle (PPV/SB) for repair of primary rhegmatogenous retinal detachment (RRD) with associated vitreous hemorrhage (VH). DESIGN: Retrospective, observational study. PARTICIPANTS: Patients with RRD and associated VH who underwent PPV or PPV/SB from January 1, 2010, through August 31, 2020, were analyzed. METHOD: We performed a single-institution, retrospective, observational study of 224 eyes with RRD and VH at the time of detachment. We excluded eyes with <6 months of follow-up, a prior history of retinal detachment (RD) repair with vitrectomy or SB, VH that resolved before surgical intervention, and tractional or combined tractional and rhegmatogenous detachments. MAIN OUTCOME MEASURES: Single-surgery anatomic success (SSAS) at 6 months, defined as no recurrent RD requiring surgical intervention. RESULTS: Pars plana vitrectomy and PPV/SB were performed on 138 eyes (62%) and 85 eyes (38%), respectively. The mean age of the PPV and PPV/SB patients was 61.9 and 60.2 years, respectively. Single-surgery anatomic success was achieved in 107 of 138 eyes (77.5%) that underwent PPV and 78 of 85 eyes (91.7%) that underwent PPV/SB. The difference in SSAS between types of treatment was significant (P = 0.006). Mean visual acuity improvement in the PPV/SB group was 0.54 logMAR units greater than that in the PPV group (P = 0.126). The incidence of postoperative proliferative vitreoretinopathy in the PPV/SB group (11.7%) was lower than that in the PPV group (19.5%; P = 0.128). The rate of repeat PPV for non-RD reasons was similar for both the groups (P = 0.437). Final reattachment status was achieved in 137 of the 138 and 84 of the 85 eyes in the PPV and PPV/SB groups, respectively. Final visual acuity improvement was significantly better in eyes with PPV/SB than in eyes with PPV alone (logMAR 2.12 vs. 1.26, respectively; P = 0.011). CONCLUSIONS: In patients with RRD and VH, SSAS was superior in patients treated with PPV/SB compared with those treated with PPV alone. Although not significantly different, the PPV/SB group had better visual outcomes and a lower postoperative proliferative vitreoretinopathy rate.

Purtscher-Like Retinopathy in a Patient with COVID-19.

The emerging literature on the novel coronavirus pandemic has reported several cases of varied retinal findings in patients with COVID-19. We report the case of a 59-year-old male who presented with complaint of bilateral blurry vision following hospital discharge after prolonged hospitalization for severe COVID-19 illness. On ocular exam, the patient demonstrated bilateral cotton wool spots localized to the posterior pole of each eye. Multimodal imaging demonstrated findings consistent with retinal nerve fiber layer infarcts in the areas of the cotton wool spots. Exam and imaging of our patient were most consistent with a Purtscher-like retinopathy. We suggest that as ophthalmologists care for increasing numbers of patients recuperating from COVID-19, they monitor for microangiopathic changes similar to those in our patient.

Clinical Outcomes in Sequential, Bilateral Rhegmatogenous Retinal Detachment: A Multicenter, Paired-Eye Analysis.

PURPOSE: To assess the clinical outcomes in patients with sequential, bilateral rhegmatogenous retinal detachment (RRD) by using a paired-eye comparison. DESIGN: Multicenter, retrospective cohort study. PARTICIPANTS: Patients with sequential, bilateral RRD treated with pars plana vitrectomy (PPV), scleral buckle (SB), or PPV plus SB over an 11-year period (October 2008-April 2019) from 4 vitreoretinal practices were included. METHODS: Data were collected on patient demographics, anatomic characteristics of the RRD, surgical procedures, and best-corrected visual acuity (VA). These variables, along with single-operation anatomic success (SOAS) and type and number of surgical procedures, were assessed with a paired-eye comparison. MAIN OUTCOME MEASURES: Single-operation anatomic success between the initial-eye and subsequent-eye RRD. RESULTS: Five hundred four eyes of 252 patients were included. The mean interval between RRD in either eye was 13.6 ± 13.4 months. Single-operation anatomic success in the initial eye was 82.5% with a mean of 1.2 surgeries (range, 1-4 surgeries). Single-operation anatomic success in the subsequent eye was 83.7% (P = 0.80) with a mean of 1.2 surgeries (range, 1-4 surgeries; P = 0.68). Visual acuity was better in the subsequent eye at presentation (mean, 20/62 vs. 20/149; P < 0.001) and postoperative month 6 (mean, 20/41 vs. 20/49; P = 0.03), but final VA was similar (20/36 vs. 20/37; P = 0.68). Macular detachment was less prevalent (34.1% vs. 56.0%; P < 0.001) with fewer quadrants detached (mean, 1.9 quadrants vs. 2.0 quadrants; P = 0.010) in the subsequent eye. Mean duration of symptoms was shorter in the subsequent eye (mean, 5.9 days vs. 7.5 days; P = 0.008). In patients who underwent a different surgical technique in each eye, PPV plus SB yielded a higher SOAS of 89.7% compared with 69.0% for PPV alone in 116 eyes (P = 0.010). CONCLUSIONS: In this study of sequential, bilateral RRD, the SOAS was similar for each eye. The second eye was more likely to be treated earlier and to have less macular involvement, but the final VA outcomes were similar. Pars plana vitrectomy plus SB yielded a significantly higher SOAS than PPV or SB alone.
