An unusual case of rapid resolution of bilateral vitelliform deposits after discontinuation of pentosan polysulfate sodium.

Purpose: To report the structural and functional changes in a 67-year-old male with pentosan polysulfate sodium (PPS) maculopathy with a progressive resolution of bilateral vitelliform lesions after PPS cessation. Observations: The patient was initially seen after taking daily PPS for over 26 years. Three months after discontinuing PPS, the bilateral vitelliform lesions identified on spectral-domain optical coherence tomography (SD-OCT) at initial consultation had completely resolved. Bilateral resolution of vitelliform lesions was associated with a decline in best-corrected visual acuity, and ellipsoid zone disruption on SD-OCT. Conclusions and importance: Several PPS maculopathy phenotypes have been previously described including vitelliform lesions. Our case highlights that discontinuing PPS may lead to rapid resolution of vitelliform lesions in PPS maculopathy and may be associated with a rapid reduction in vision.

The Sensitivity of Ultra-Widefield Fundus Photography Versus Scleral Depressed Examination for Detection of Retinal Horseshoe Tears.

PURPOSE: Ultra-widefield (UWF) imaging is commonly used in ophthalmology in tandem with scleral depressed examinations (SDE) to evaluate peripheral retinal disease. Because of the increased reliance on this technology in tele-ophthalmology, it is critical to evaluate its efficacy for detecting the peripheral retina when performed in isolation. Therefore, we sought to evaluate UWF imaging sensitivity in detecting retinal horseshoe tears (HSTs). STUDY DESIGN: Retrospective clinical validity and reliability study. METHODS: A single-institutional retrospective analysis was performed on patients at the Shiley Eye Institute, University of California, San Diego. Patients with HSTs seen on SDE who underwent treatment with laser were included in the study. A total of 140 patients with HSTs in the right and/or left eyes met the inclusion criteria. Those with concomitant ruptured globes, retinal detachments, and vitreous hemorrhages were excluded. A total of 123 patients with 135 HSTs were included in the final analysis. The primary outcome was the number of HSTs detected by UWF imaging. A secondary outcome was HST location. Sensitivity was measured with respect to HST location, and statistical significance was calculated by Fisher exact testing. RESULTS: A total of 69 (51.1%) HSTs were visualized on UWF images and 66 (48.9%) were not visualized. The sensitivity of UWF imaging in capturing HSTs was 7 of 41 (17.1%), 8 of 25 (32.0%), 7 of 14 (50.0%), and 47 of 55 (85.5%) for the superior, inferior, nasal, and temporal quadrants, respectively. Sensitivities between HST visibility and location were statistically significant (P < .001). CONCLUSIONS: Nearly half of HSTs were missed by UWF imaging. This study demonstrates that UWF imaging alone is not sufficiently sensitive to exclude the presence of HSTs.

Improved Visual Outcomes after Severe Open-Globe Injuries Associated with Perioperative Vitreoretinal Evaluation.

PURPOSE: To investigate the impact of perioperative evaluation by a vitreoretinal surgeon on outcomes after severe open-globe injury (OGI). DESIGN: Retrospective, comparative study. SUBJECTS: Open-globe injury cohorts from 2 academic United States ophthalmology departments with disparate OGI management protocols and vitreoretinal referral patterns. METHODS: Patients with severe OGI (presenting visual acuity [VA] of counting fingers or worse) from the University of Iowa Hospitals and Clinics (UIHC) were compared with patients with severe OGI from the Bascom Palmer Eye Institute (BPEI). At UIHC, almost all cases of OGI were repaired by anterior segment surgeons, with postoperative vitreoretinal referral at the surgeon's discretion. In contrast, at BPEI, all OGIs were both repaired and managed postoperatively by a vitreoretinal surgeon. MAIN OUTCOME MEASURES: Rate of vitreoretinal surgeon evaluation, rate of pars plana vitrectomy (PPV) (either primary or secondary), and VA at the last follow-up. RESULTS: Overall, 74 subjects from UIHC and 72 subjects from BPEI met the inclusion criteria. There were no differences in preoperative VA or rates of vitreoretinal pathology. The rate of vitreoretinal surgeon evaluation was 100% at BPEI and 65% at UIHC (P < 0.001), and the rate of PPV was 71% at BPEI and 40% at UIHC (P < 0.001). Median VA at the last follow-up in the BPEI cohort was 1.35 logarithm of the minimum angle of resolution (logMAR) (interquartile range [IQR], 0.53-2.30, corresponding to a Snellen VA of ∼ 20/500) compared with a median VA of 2.70 logMAR (IQR, 0.93-2.92, corresponding to a Snellen VA of light perception) in the UIHC cohort (P = 0.031). Overall, 68% of patients in the BPEI cohort had an improvement in VA from presentation to last follow-up versus 43% in the UIHC cohort (P = 0.004). CONCLUSIONS: Automatic perioperative evaluation by a vitreoretinal surgeon was associated with a higher rate of PPV and improved visual outcomes. Prompt evaluation by a vitreoretinal surgeon, either preoperatively or in the early postoperative period, should be considered, when logistically feasible, in severe OGIs because PPV is frequently indicated and may result in significant visual improvement.

Surgical Outcomes of Acute Retinal Necrosis-Related Retinal Detachment in Polymerase Chain Reaction-Positive Patients: A Single-Center Experience.

PURPOSE: To evaluate the clinical features, operative techniques, and surgical outcomes of patients who underwent surgery for acute retinal necrosis (ARN)-related retinal detachment (RD). DESIGN: Retrospective, longitudinal, consecutive case series. PARTICIPANTS: Patients with polymerase chain reaction-positive ARN presenting from 2011 to 2021 who underwent vitreoretinal surgery for ARN-related RD at our institution. METHODS: Univariate, multivariate, and survival analyses were used to determine predictors of anatomic and functional outcomes. MAIN OUTCOME MEASURES: Single-surgery anatomic success rate, recurrent RD, and visual acuity (VA) at 1 year. RESULTS: Thirty-four eyes of 34 patients (32.4% women, mean age, 45.1 ± 20.4 years) were included for analysis with a median follow-up of 2.5 years (interquartile range [IQR], 0.8-5.5 years). Presenting VA was 1.1 ± 0.8 logarithm of the minimum angle of resolution (LogMAR) (Snellen ∼20/250). The median time from presentation to RD surgery was 1.7 months (IQR, 0.8-4.1 months), and the mean preoperative VA was 1.6 ± 0.8 LogMAR (Snellen ∼20/800). Small-gauge pars plana vitrectomy (PPV) with or without a scleral buckle (SB) was performed for all eyes with an overall single-surgery success rate of 63.6%, with no statistically significant differences in visual/anatomic outcomes between PPV and PPV/SB cases. Silicone oil was used for tamponade in 33 (97.1%) cases and was removed in 10 (30.3%) with good anatomic and final functional outcomes (Snellen âˆ¼20/80). Independent predictors of recurrent RD included the female sex (hazard ratio, 8.38; 95% confidence interval, 2.03-34.68; P < 0.01) and zone 1 retinitis involvement at presentation (hazard ratio, 10.95; 95% confidence interval, 2.12-56.48; P < 0.01). The mean VA at 1 year (VA1year) and at the final follow-up both had a Snellen equivalent of 20/640 (P > 0.05 for both compared with preoperative VA, respectively). Eyes that achieved single-surgery success had VA1year of 20/200 versus hand movements in those with single-surgery failure (P < 0.01). On multivariate linear regression, younger age (P = 0.04) and better presenting VA (P < 0.01) were both associated with better VA1year. CONCLUSIONS: Moderate single-surgery anatomic success can be achieved with modern vitreoretinal surgical techniques for ARN-related RD, although visual outcomes remain poor. Further studies investigating interventions for increasing single-surgery success rates, for the inflammatory complications of ARN, and for preventing ARN-related RD are needed.

Endophthalmitis Associated with a Retained Cilium in the Clear Corneal Wound after Cataract Surgery.

We report a case of endophthalmitis occurring secondary to a retained cilium in a clear corneal wound after cataract surgery. A 67-year-old female presented to an ophthalmology emergency room with light perception vision in the right eye 5 days after routine cataract surgery. Examination of the right eye demonstrated decreased vision, conjunctival injection, a corneal endoplaque, and anterior chamber fibrin. Additionally, a cilium was visible in the clear corneal incision. A vitreous aspiration and injection of antibiotics and steroid were performed, and the patient underwent a vitrectomy the next day. Intraoperative cultures and culture of the cilium grew Staphylococcus epidermidis. One year after vitrectomy, the patient's vision recovered to 20/25 in the operated eye. In conclusion, a retained cilium in a clear corneal wound related to cataract surgery, though rare, may result in endophthalmitis. The surgical field should be cleared of cilia on the ocular surface prior to surgery. Proper draping and use of povidone-iodine antisepsis are essential in reducing the risk of endophthalmitis.

Case report: Vitreous hemorrhage as the presenting sign of retinal cavernous hemangioma in a newborn.

PURPOSE: To report a case of vitreous hemorrhage as the presenting sign of retinal cavernous hemangioma (RCH) in a newborn. OBSERVATIONS: A five-week-old full-term male with a history of seizures and birth trauma underwent ophthalmology screening. Initial eye examination revealed vitreous hemorrhage. Subsequent examination under anesthesia with multi-modal imaging revealed vitreous hemorrhage and an intra-retinal mass with numerous sac-like aneurysmal dilatations, consistent with RCH. CONCLUSIONS AND IMPORTANCE: Vitreous hemorrhage in a neonate is an atypical presentation of RCH. Clinicians should be aware that birth trauma may lead to vitreous hemorrhage from RCH. This is the first description of RCH, a rare retinal vascular tumor, in a newborn.

WIDE-FIELD SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY OF DIABETIC TRACTIONAL RETINAL DETACHMENTS BEFORE AND AFTER SURGICAL REPAIR.

PURPOSE: Wide-field (WF) swept-source (SS) optical coherence tomography angiography (SS-OCTA) was used to image diabetic tractional retinal detachments (TRDs) before and after pars plana vitrectomy. The clinical utility of SS-OCTA was assessed. METHODS: Patients with diabetic TRDs were imaged prospectively with SS-OCTA. Ultrawide-field imaging was obtained when possible. Postoperative WF SS-OCTA imaging was performed. RESULTS: From January 2018 through December 2019, 31 eyes of 21 patients with diabetic TRDs were imaged. Wide-field SS-OCTA en-face images captured all areas of TRD and fibrovascular proliferation within the posterior pole that were visualized on ultrawide-field imaging. Optical coherence tomography angiography B-scans revealed the vascularity of preretinal membranes and identified areas of vitreoretinal traction and posterior vitreous detachment. Ten eyes underwent pars plana vitrectomy. Postoperative SS-OCTA imaging demonstrated removal of fibrovascular membranes, relief of traction, and resolution of TRDs. Retinal ischemia before and after surgical repair appeared similar. CONCLUSION: All clinically relevant features of diabetic TRDs were identified at baseline and assessed longitudinally after pars plana vitrectomy using WF SS-OCTA, which showed resolution of vitreoretinal traction and no apparent change in the status of retinal perfusion after surgery. If the media are clear and fixation is adequate, WF SS-OCTA is likely the only imaging modality needed for the diagnosis and longitudinal evaluation of diabetic TRDs.

Retinoschisis in Coats Disease: Clinical Picture, Therapeutic Considerations, and Management Outcomes.

Purpose: Retinoschisis in inflammatory and exudative retinopathy is a known but rare entity. We describe the presentation and clinical and surgical outcomes of a series of patients with retinoschisis in the setting of Coats disease. Methods: This retrospective case series of patients with Coats disease recorded visual acuity and the number and type of treatments (eg, angiography-guided photocoagulation, intravitreal bevacizumab, sub-Tenon triamcinolone, or vitreoretinal surgery). Results: Eighteen of 133 patients with Coats disease were diagnosed with retinoschisis by color imaging. All (100%) of the areas of schisis or macrocyst were associated with dense subretinal exudation, whereas only 7 (38.8%) were associated with exudative retinal detachment. Initial best-corrected visual acuity in the schisis cohort was 1.14 ± 1.19 (Snellen equivalent, 20/276) vs 1.42 ± 1.40 (Snellen, 20/526) in those without (P = .56). Final best-corrected visual acuity was 1.76 ± 1.37 (Snellen, 20/1150) and 1.45 ± 1.44 (Snellen, 20/563), respectively (P = .43). The mean number of treatments in individuals with schisis was 4.8 ± 2.9 for angiography-guided photocoagulation, 4.5 ± 2.9 for intravitreal bevacizumab, and 1.7±1.2 for sub-Tenon triamcinolone. Intraocular surgery was required in 39% (7 of 18) of patients with schisis vs 22% (25 of 115) for patients without schisis (P = .14). One eye required enucleation, and histopathology of the schisis pocket was obtained. Conclusions: The pathophysiology of retinoschisis in Coats disease is not completely understood. We propose that telangiectatic leakage, hypoxia, and toxicity to the retinal pigment epithelial cells play a role in cavity development, and therefore may represent a clinical feature of advanced or uncontrolled disease.

Comparison Between Graders in Detection of Diabetic Neovascularization With Swept Source Optical Coherence Tomography Angiography and Fluorescein Angiography.

PURPOSE: We compared the ability of ophthalmologists to identify neovascularization (NV) in patients with proliferative diabetic retinopathy using swept-source optical coherence tomography angiography (SS-OCTA) and fluorescein angiography (FA). DESIGN: Retrospective study comparing diagnostic instruments. METHODS: Eyes with proliferative diabetic retinopathy or severe nonproliferative diabetic retinopathy and a high suspicion of NV based on clinical examination were imaged using SS-OCTA and FA at the same visit. Two separate grading sets consisting of scrambled, anonymized SS-OCTA and FA images were created. The ground truth for presence of NV was established by consensus of 2 graders with OCTA experience who did not participate in the subsequent assessment of NV in this study. The 2 anonymized image sets were graded for presence or absence of NV by 12 other graders that included 2 residents, 6 vitreoretinal fellows, and 4 vitreoretinal attending physicians. The percentage of correct grading of NV using SS-OCTA and FA was assessed for each grader and across grader training levels. RESULTS: Forty-seven eyes from 24 patients were included in this study. Overall, the mean percentage of correct NV grading was 87.8% using SS-OCTA with B-scans and 86.2% using FA (P = .92). Assessing each grader individually, there was no statistically significant asymmetry in correct grading using SS-OCTA and FA. CONCLUSIONS: Ophthalmologists across training levels were able to identify diabetic NV with equal accuracy using SS-OCTA and FA. Based on these results, SS-OCTA may be an appropriate standalone modality for diagnosing diabetic NV.

Surgical Removal of Intraocular Parasite in a Patient With Diffuse Unilateral Subacute Neuroretinitis.

Diffuse unilateral subacute neuroretinitis (DUSN) is a rare ocular infectious disease caused by migrating larvae of a nematode. DUSN is often a diagnostic challenge as it is difficult to identify the pathogenic nematode on funduscopic examination because it moves frequently and often resides within the subretinal space. Herein, the authors present a patient with unilateral, chronic visual loss who was noted to have a live, motile worm within the vitreous cavity. Initial attempts to treat with laser photocoagulation were unsuccessful. In the accompanying video, the authors report the first case of a live intraocular parasite successfully removed with pars plana vitrectomy.

Longitudinal Angiographic Evidence That Intraretinal Microvascular Abnormalities Can Evolve into Neovascularization.

PURPOSE: The hallmark of proliferative diabetic retinopathy (PDR) is retinal neovascularization. Tortuous intraretinal vascular segments known as intraretinal microvascular abnormalities (IRMAs) are a known risk factor for neovascularization (NV), but whether IRMA represents a biomarker or a vascular precursor lesion to NV has not been demonstrated. The purpose of this study was to determine whether IRMA may evolve directly into NV. DESIGN: Retrospective analysis of prospective, observational case series. PARTICIPANTS: Patients with treatment-naïve PDR. METHODS: Patients were imaged longitudinally with fluorescein angiography (FA) and swept-source (SS) OCT angiography (OCTA) before and after panretinal photocoagulation (PRP). MAIN OUTCOME MEASURES: Presence and colocalization of IRMA and NV on serial FA and SS OCTA. RESULTS: Two PDR patients showed multiple NV and IRMA lesions at baseline examination. Three months after PRP, FA demonstrated profuse leakage from 3 new NV lesions in one patient and 1 new NV lesion in another patient. Multimodal imaging showed that these 4 lesions were IRMAs at baseline. Swept-source OCTA performed before PRP and 1 week, 1 month, and 3 months after PRP confirmed that the precursor IRMA lesions were intraretinal tortuous vascular lesions at baseline and that they developed into preretinal NV with contiguous intraretinal components. NV was found to develop and adhere to the posterior hyaloid even in areas of pre-existing hyaloidal detachment. CONCLUSIONS: Diabetic retinal NV can develop from IRMA. Early identification of IRMAs may be an accurate means of predicting progression to PDR, and frequent monitoring of IRMAs with SS OCTA may facilitate early diagnosis of PDR.

Genotypic and Phenotypic Antibiotic Resistance in Staphylococcus Epidermidis Endophthalmitis.

BACKGROUND AND OBJECTIVE: To evaluate antibiotic resistance patterns in Staphylococcus epidermis endophthalmitis isolates, identify antibiotic resistance genes, and compare this to their phenotypic resistance. MATERIALS AND METHODS: Retrospective case series of S. epidermidis isolates from January 2012 to December 2017. Phenotypic resistance was determined from minimum inhibitory concentration values. Genotypic resistance was determined from DNA microarray. The relationship between these was analyzed using Cohen's kappa and predictive value. RESULTS: Seventy-five isolates were included. More than 60% were resistant to methicillin and erythromycin. Approximately 60% possessed the resistance genes for methicillin and erythromycin, and 25% for clindamycin. There was near perfect agreement between genotype and phenotype for erythromycin and methicillin (kappa = 0.88 and 0.89, respectively). Approximately 98% (P < 0.0001) of isolates with erythromycin and methicillin resistance genes and 90% (P = 0.0006) with clindamycin resistance genes were phenotypically resistant to those antibiotics. None were resistant to vancomycin. CONCLUSION: The relationship between genotypic and phenotypic antibiotic resistance highlights that resistance may be polygenic, and genes may be silent.

Retinal Nonperfusion in Proliferative Diabetic Retinopathy Before and After Panretinal Photocoagulation Assessed by Widefield OCT Angiography.

PURPOSE: Widefield swept source optical coherence tomography angiography (WF SS-OCTA) imaging was compared with ultra-widefield (UWF) fluorescein angiography (FA) imaging to better understand changes in retinal nonperfusion before and after panretinal photocoagulation (PRP) in treatment-naïve eyes with proliferative diabetic retinopathy (PDR). DESIGN: Prospective, observational, consecutive case series. METHODS: Participants with treatment-naïve PDR were imaged using the SS-OCTA 12- × 12-mm scan pattern at baseline and at 1 week, 1 month, and 3 months after PRP. UWF FA was obtained at baseline and 3 months after PRP. Selected eyes were imaged using 5 SS-OCTA 12- × 12-mm scans to create a posterior pole montage, and 5 eyes also underwent SS-OCTA imaging at 6 months and 1 year. Areas of retinal nonperfusion (RNP) were drawn independently by 2 masked graders, and analysis of variance (ANOVA) tests were used to compare areas of RNP over time. Main outcome measurements consisted of areas and boundaries of RNP visualized using WF SS-OCTA and UWF FA. RESULTS: From January 2018 through January 2019, WF SS-OCTA was performed on 20 eyes with treatment-naïve PDR from 15 patients. Areas of RNP identified on UWF FA images co-localized with RNP areas visualized on WF SS-OCTA images. There were no statistically significant changes in RNP area on WF SS-OCTA images through 3 months after PRP. Even eyes that were severely ischemic at baseline had no significant changes in RNP area 1 year after PRP. CONCLUSIONS: RNP in PDR can be identified at baseline and imaged serially after PRP using WF SS-OCTA. Retinal perfusion in PDR does not change significantly after PRP. The ability of WF SS-OCTA to longitudinally evaluate RNP areas provides additional justification for adopting WF SS-OCTA as the sole imaging modality for clinical management of PDR.

Masqueraders of multiple evanescent white dot syndrome (MEWDS).

PURPOSE: To describe disorders that can masquerade as multiple evanescent white dot syndrome (MEWDS). DESIGN: Retrospective, multicenter case series. PARTICIPANTS: Patients who presented with clinical findings compatible with a diagnosis of MEWDS but were ultimately diagnosed with an alternative inflammatory, infectious, or neoplastic disorder. METHODS: Clinical records and multimodal imaging findings including fundus photography, fundus autofluorescence (FAF), fluorescein angiography (FA), indocyanine green angiography (ICGA), optical coherence tomography (OCT), and OCT angiography (OCTA) were analyzed. MAIN OUTCOME MEASURES: Inclusion criteria to be defined as a masquerade syndrome for MEWDS included the presence of disseminated grayish-white outer retinal spots that were hyperautofluorescent on FAF and associated with ellipsoid zone (EZ) disruption on OCT. RESULTS: Twenty-two eyes of 13 patients were identified. All patients presented with the classic findings of MEWDS listed above. A MEWDS-like presentation was bilateral in nine of 13 patients (69%). Final diagnosis was determined on the basis of additional investigations including serologies and biopsy. These diagnoses included syphilis (three patients), lymphoma (three patients), idiopathic multifocal choroiditis (two patients), idiopathic retinal phlebitis (one patient), idiopathic acute zonal occult outer retinopathy (one patient), sarcoidosis (one patient), tuberculosis (one patient), and cancer-associated retinopathy (one patient). The outer retinal lesions and imaging findings resolved with treatment for the associated systemic disorders. CONCLUSIONS: Widespread grayish-white outer retinal spots associated with hyperautofluorescence on FAF and disruption of the EZ on OCT are not pathognomonic for MEWDS. A high index of suspicion must be maintained for masqueraders of MEWDS, which can include serious inflammatory, infectious, and neoplastic disorders.

Distribution of Diabetic Neovascularization on Ultra-Widefield Fluorescein Angiography and on Simulated Widefield OCT Angiography.

PURPOSE: Areas of neovascularization (NV) in proliferative diabetic retinopathy (PDR) on ultra-widefield (UWF) fluorescein angiography (FA) were identified and compared with a simulated widefield (WF) swept-source OCT angiography (SS-OCTA) field of view to determine whether the WF SS-OCTA field of view was sufficient for detection of NV in PDR. DESIGN: Retrospective, consecutive case series. METHODS: All patients with PDR and UWF FA imaging at the Bascom Palmer Eye Institute over a period of 5.5 years were identified. UWF FA images were reviewed and sites of NV were identified either as NV of the disc or NV elsewhere. Sites of NV elsewhere were classified by disc-centered retinal quadrants. A simulated WF SS-OCTA montage field of view was overlaid on the UWF FA images to determine whether sites of NV would have been identified by this simulated WF SS-OCTA field of view. RESULTS: A total of 651 eyes with PDR from 433 patients had at least 1 UWF FA with NV. Of the 651 eyes, 50% were treatment-naïve, 9.8% had NV of the disc only, 41.8% had NV elsewhere only, and 48.4% had both NV of the disc and NV elsewhere. NV elsewhere was most prevalent in the superotemporal quadrant and the least prevalent in the nasal quadrants. When the simulated WF SS-OCTA field of view was overlaid on the UWF FA, 98.3% of all eyes, 99.4% of treatment-naive eyes, and 97.2% of previously treated eyes had NV within the WF SS-OCTA field of view. In those eyes with a repeat UWF FA within 6 to 18 months of the first FA, the distribution of NV did not change in either the treatment-naive or previously treated eyes. CONCLUSIONS: NV elsewhere in PDR was most prevalent superotemporally, and 99.4% of treatment-naïve eyes had NV within the simulated WF SS-OCTA field of view. Combined with previous research using WF SS-OCTA to identify NV in PDR, these findings suggest that WF SS-OCTA may be the only imaging modality needed for the diagnosis and longitudinal management of PDR.

An Eight-Year-Old Girl Presents With Two Weeks of Vision Loss and Nightly Headaches.

Intraocular medulloepithelioma is a rare congenital tumor that arises from the nonpigmented epithelium of the ciliary body. It is the second most common primary intraocular neoplasm during the first decade of life. It may present with an iris mass or cyst (56%), glaucoma (48%), cataract (26%), leukocoria (18%), decrease in vision (41%), or pain (30%). Here, the authors present a case of a medulloepithelioma investigated with multimodal imaging, including the first characterization with intraoperative optic coherence tomography.

Longitudinal Examination of Fellow-Eye Vascular Anomalies in Coats' Disease With Widefield Fluorescein Angiography: A Multicenter Study.

BACKGROUND AND OBJECTIVE: Retinovascular anomalies in the fellow eyes of patients with Coats' disease have been described, but the clinical significance is unknown, as well as whether these lesions progress over time. PATIENTS AND METHODS: This is an international, multicenter, retrospective, observational cohort study of fellow-eye abnormalities on widefield fluorescein angiography in patients with Coats' disease. RESULTS: Three hundred fifty eyes of 175 patients with Coats' disease were analyzed. A total of 33 patients (18.8%) demonstrated abnormal fellow-eye findings: 14 (42.4%) telangiectasias, 18 (54.5%) aneurysms, six (18.2%) segmental non-perfusion, six (18.2%) leakage, and two (6.0%) vascular tortuosity. All eyes were asymptomatic, and none of the lesions progressed over time. There was no association between fellow-eye findings with severity of Coats' disease (P = .16), patient age (P = .16), or presence of systemic vascular disease (P = .16). CONCLUSIONS: The vascular abnormalities in fellow eyes of patients with Coats' disease did not progress over time. Observation is a reasonable initial management strategy.
