METformin for the MINimization of Geographic Atrophy Progression (METforMIN): A Randomized Trial.

Purpose: Metformin use has been associated with a decreased risk of age-related macular degeneration (AMD) progression in observational studies. We aimed to evaluate the efficacy of oral metformin for slowing geographic atrophy (GA) progression. Design: Parallel-group, multicenter, randomized phase II clinical trial. Participants: Participants aged ≥ 55 years without diabetes who had GA from atrophic AMD in ≥ 1 eye. Methods: We enrolled participants across 12 clinical centers and randomized participants in a 1:1 ratio to receive oral metformin (2000 mg daily) or observation for 18 months. Fundus autofluorescence imaging was obtained at baseline and every 6 months. Main Outcome Measures: The primary efficacy endpoint was the annualized enlargement rate of the square root-transformed GA area. Secondary endpoints included best-corrected visual acuity (BCVA) and low luminance visual acuity (LLVA) at each visit. Results: Of 66 enrolled participants, 34 (57 eyes) were randomized to the observation group and 32 (53 eyes) were randomized to the treatment group. The median follow-up duration was 13.9 and 12.6 months in the observation and metformin groups, respectively. The mean ± standard error annualized enlargement rate of square root transformed GA area was 0.35 ± 0.04 mm/year in the observation group and 0.42 ± 0.04 mm/year in the treatment group (risk difference = 0.07 mm/year, 95% confidence interval = -0.05 to 0.18 mm/year; P = 0.26). The mean ± standard error decline in BCVA was 4.8 ± 1.7 letters/year in the observation group and 3.4 ± 1.1 letters/year in the treatment group (P = 0.56). The mean ± standard error decline in LLVA was 7.3 ± 2.5 letters/year in the observation group and 0.8 ± 2.2 letters/year in the treatment group (P = 0.06). Fourteen participants in the metformin group experienced nonserious adverse events related to metformin, with gastrointestinal side effects as the most common. No serious adverse events were attributed to metformin. Conclusions: The results of this trial as conducted do not support oral metformin having effects on reducing the progression of GA. Additional placebo-controlled trials are needed to explore the role of metformin for AMD, especially for earlier stages of the disease.

Bilateral Combined Rhegmatogenous and Tractional Retinal Detachments Due to Persistent High-Titer Syphilis.

A 23-year-old man developed bilateral rhegmatogenous retinal detachments secondary to high-titer ocular syphilis. The patient's titer increased four-fold after completing a 14-day course of intravenous penicillin (IVP). He underwent bilateral pars plana vitrectomy with silicone oil fill in both eyes. In this article, the authors propose an updated treatment method for patients with advanced ocular syphilis that includes oral doxycycline for 30 days following 14 days of IVP to optimally minimize the patient's infectious burden. Following surgery and this new treatment regime, this patient's best-corrected visual acuity 10 weeks postoperatively measured 20/50 in the right eye and 20/30 in the left eye. This case highlights a rare but devastating complication of ocular syphilis. We suggest the addition of oral doxycycline to IVP for patients with syphilis titers ≥ 1:256, HIV co-infection, and presence of posterior retinitis.

Risk for Surgical Team Hearing Loss With Vitrectomy.

Purpose: To assess sound-level exposure during vitrectomy using 3 of the most common commercially available machines. Methods: This noninterventional cross-sectional study examined sound emission from the Constellation, Stellaris, and EVA vitrector systems. For each machine, a noise dosimeter was used to measure the sound-level exposure of the surgeon during 3 surgical cases in which vitrectomy was performed. Sound levels associated with progressively increasing cut rates and vacuum pressures were also measured. Finally, sound measurements were taken during the use of various additional functions of each machine, including diathermy, laser, and extrusion. Sound levels were compared with occupational health guidelines in Canada and the United States. Results: The maximum sound level recorded during vitrectomy surgery was 88.2 dBA. The mean sound level during vitrectomy surgical cases ranged from 58.5 to 66.8 dBA. A strong positive linear correlation was found between the cut rate and sound level (r = 0.88-0.98) and the vacuum pressure and sound level (r = 0.83-0.97). This relationship was consistent across the 3 vitrector systems (P < .001). Conclusions: Noise exposure during vitrectomy procedures was acceptable but may be sufficient for surgical team activity interference, as described by World Health Organization recommendations. A strong correlation was found between the cut rate and noise exposure. If cut rates continue to increase, attention should be given to ensure that the resulting noise exposure does not threaten the hearing of vitreoretinal surgeons and the operating room staff.

Brolucizumab-associated intraocular inflammation in eyes without retinal vasculitis.

PURPOSE: To analyze a series of eyes with brolucizumab-associated intraocular inflammation (IOI) without retinal vasculitis reported to the American Society of Retina Specialists (ASRS). METHODS: The ASRS Research and Safety in Therapeutics (ReST) Committee analyzed clinical characteristics from submitted reports of IOI after brolucizumab. Eyes with retinal vasculitis or that received intraocular antibiotics were excluded. RESULTS: Forty-nine eyes of 45 patients were collected. Mean visual acuity (VA) at baseline was 20/49 (range 20/20 - 5/200). Patients presented with IOI a mean of 24 (range 3-63) days after most recent brolucizumab injection; 61% presented for an unscheduled visit while 39% presented at routine follow-up. Mean VA at IOI presentation was 20/67 (range 20/20 - 3/200). Most common symptoms were floaters (78%) and blurry vision (76%). Pain (20%) and redness (16%) were less common; 3 (6%) eyes were asymptomatic. IOI was anterior only in 18%, posterior only in 31%, and both anterior and posterior in 51% of eyes. Treatment included topical steroids alone in 67% eyes, while 10% eyes received no treatment. Mean VA at last follow-up was 20/56 (range 20/20 - 1/200). Three (6%) eyes lost 3 or more lines and 1 (2%) eye lost 6 or more lines. CONCLUSIONS: Brolucizumab-associated IOI without retinal vasculitis typically presented with a delayed onset of a few weeks. Often, visual acuity decline was relatively mild. Most symptoms resolved and nearly all had a return to baseline VA, but a small percentage of patients had a significant decrease in VA at last follow-up.

Self-Induced Bilateral Retinal Detachments and Traumatic Cataracts in a Patient With Bohring-Opitz Syndrome.

A 9-year-old female with a history of Bohring-Opitz syndrome (BOS), Down syndrome, and autism initially presented with bilateral cataracts and a total retinal detachment in her left eye secondary to chronic self-injurious behavior. The authors report the first case of self-induced retinal detachment and traumatic cataracts in a patient with BOS. For patients who present with self-injurious behavior, the authors advocate for behavioral modifications at home, including the use of "no-no's," supplemental medication if necessary, and behavioral therapy to reduce the risk of self-induced visual injury. The authors also suggest the use of 25-gauge vitrectomy with silicone oil for retinal detachment repair. Finally, given the high risk of irreversible vision loss from amblyopia and recurrent retinal detachments in children with BOS and self-injurious behavior, the authors recommend regular 2-month interval ophthalmic follow-up.

CHOROIDAL NEOVASCULARIZATION AND CHORIORETINAL ATROPHY IN A PATIENT WITH MELANOMA-ASSOCIATED RETINOPATHY AFTER IPILIMUMAB/NIVOLUMAB COMBINATION THERAPY.

PURPOSE: To describe a case of choroidal neovascularization (CNV) and chorioretinal scarring in a patient with melanoma-associated retinopathy after ipilimumab/nivolumab combination immune therapy for malignant melanoma. METHODS: Retrospective case report with fundus photography, fluorescein angiography, optical coherence tomography, and electroretinography. RESULTS: A 65-year-old woman presented with symptoms of photopsia and visual field loss. She had previously undergone ipilimumab/nivolumab combination chemotherapy treatment for malignant melanoma 14 months earlier coinciding with the onset of her visual symptoms. Fundus photography showed bilateral atrophic chorioretinal lesions and peripheral retinal pigment epithelial changes. Fluorescein angiography revealed retinovascular leakage in both eyes with CNV in the right eye. Optical coherence tomography showed a pigment epithelial detachment with subretinal fluid and subretinal hyperreflective material consistent with occult CNV. Visual field testing showed generalized visual field loss in both eyes. Bloodwork discovered an elevated angiotensin-converting enzyme. Electroretinography revealed abnormal peripheral rod and cone function with impairment of the photoreceptor and inner nuclear layer. Serum Western blot was positive for 60 kDa antiretinal autoantibody. After a single bevacizumab injection in the right eye, CNV resolved and visual acuity improved from 20/50 before the injection to 20/25 3 months after the injection. Visual acuity in the left eye deteriorated for months to counting fingers but then improved to 20/100 on follow-up examinations. CONCLUSION: Ipilimumab and nivolumab have been associated with immune-related ocular adverse effects. We report a case of combination therapy presenting with chorioretinal scarring and subsequent CNV in a patient with melanoma-associated retinopathy, a rare yet important adverse effect.

Occlusive Retinal Vasculitis Following Intravitreal Brolucizumab.

PURPOSE: To analyze a case series of retinal vasculitis reported to the American Society of Retina Specialists (ASRS) following Food and Drug Administration approval of brolucizumab for treatment of neovascular age-related macular degeneration. METHODS: The ASRS Research and Safety in Therapeutics Committee analyzed clinical and imaging characteristics from submitted reports of retinal vasculitis after brolucizumab. RESULTS: Retinal vasculitis was reported in 26 eyes of 25 patients (22 [88%] female) after treatment with brolucizumab. Imaging studies were available for 24 of 26 eyes. Most cases (92%) were associated with intraocular inflammation, which presented at a mean of 25 days (range, 3-63 days) after the most recent brolucizumab injection. Mean visual acuity (VA) was 20/52 (range, 20/25-4/200) before the adverse event, 20/151 (range, 20/25-hand motion) at presentation of the adverse event, and 20/243 (range, 20/30-light perception) at last follow-up. Twelve eyes (46%) had a greater than 3-line decrease in VA at final follow-up, and 12 eyes (46%) had a final VA of 20/200 or worse. Analysis of retinal imaging identified vasculopathy that involved retinal arteries (91%), retinal veins (79%), and choroidal vessels (48%). Occlusive disease was apparent on imaging in 83% of eyes. Treatment approaches were varied. CONCLUSIONS: Retinal vasculitis has been identified in a series of eyes following brolucizumab. Although a few eyes in this series were asymptomatic or minimally symptomatic, some eyes had significant vision loss. A careful examination for signs of active inflammation prior to brolucizumab injection is recommended. Once vasculopathy is suspected, angiographic imaging may help define the spectrum of involvement. Optimal treatment strategies remain unknown.

Ocular Ischemic Syndrome With Congenital Absence of Internal Carotid Artery.

Purpose: This article describes a case of ocular ischemic syndrome (OIS) in a patient with a congenitally absent left internal carotid artery (ICA). Methods: Retrospective case report with anterior-segment and fundus photography, fluorescein angiography (FA), and computerized tomography angiography (CT-A). Results: A 31-year-old-man was found to have neovascularization of the iris (NVI) and angle of the left eye. FA showed capillary nonperfusion in the temporal periphery. He required intravitreal bevacizumab and triamcinolone injections and 2 panretinal photocoagulation treatments for persistent rubeosis and cystoid macular edema. Transient right-eye vision loss prompted CT-A, revealing an absent left ICA. Three years following presentation, FA continued to show delayed arteriovenous flow suggestive of OIS. He has required intravitreal bevacizumab injections every 12 weeks for persistent NVI. Conclusion: Congenitally absent left ICA with resultant cerebrovascular insufficiency is a rare cause of OIS, underscoring the pathophysiological principles of insufficient blood supply to the ophthalmic artery.

TAMOXIFEN RETINOPATHY DURING TREATMENT OF AN INOPERABLE DESMOID TUMOR.

PURPOSE: To evaluate the clinical significance and rarity of tamoxifen retinopathy after a long-term tamoxifen treatment for an inoperable desmoid tumor. METHODS: Case report. RESULTS: Tamoxifen retinopathy is a condition rarely observed in clinical practice. Although tamoxifen is typically a treatment for breast cancer patients, we present a 68-year-old woman taking tamoxifen for an inoperable desmoid tumor, an equally rare condition. She presented with bilaterally deteriorating vision over the course of a year. Fundoscopic examination revealed parafoveal deposits bilaterally. Spectral domain optical coherence tomography exhibited hyperreflective deposits in all layers of the retina. She had a cumulative treatment dose of 292 g of tamoxifen, and the medication was subsequently stopped. Her vision remained stable 3 months after the cessation of tamoxifen. CONCLUSION: The development of tamoxifen retinopathy in the treatment of a desmoid tumor makes this case a rare entity, and this is the first reported case of these two concomitant conditions to our knowledge. With the use of long-term tamoxifen as a primary treatment, we recommend screening at regular intervals by an ophthalmologist as an integral part of treatment.

Protecting Vision in Patients With Diabetes With Ultra-Widefield Imaging: A Review of Current Literature.

Ultra-widefield fundus imaging (UWFI) is a relatively new technology capable of capturing 200° images of the retina. Since vision changes can be irreversible in diabetic retinopathy (DR), recognition of prognostic biomarkers in the peripheral retina may prove invaluable toward optimizing the management and reducing the societal burden of this blinding disease. Following a bibliographic review using Pubmed, OVID Medline, Embase, and the Cochrane Library, the current review systematically examined 13 studies that compared UWFI to conventional screening techniques such as seven standard field (7SF) Early Treatment In Diabetic Retinopathy Study (ETDRS) and non-mydriatic multifield fundus photography (NMFP), as well as their scientific level of evidence. Overall, UWFI had good agreement with 7SF ETDRS and NMFP, and moderate agreement with dilated fundus examination. Seven additional studies were examined that considered the significance of peripheral lesions found on UWFI. These studies demonstrated that UWFI captured additional DR pathology in the peripheral retina that may not be evident if evaluation is limited to the posterior pole and may be relevant to patient outcomes. Future directions include but are not limited to the potential of UWFI to track the progression of DR with treatment. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:639-648.].

Telemedicine for Diabetic Retinopathy Screening in an Urban, Insured Population Using Fundus Cameras in a Primary Care Office Setting.

BACKGROUND AND OBJECTIVE: This study examines the rate of adherence to recommended ophthalmology follow-up after primary care-based telemedicine diabetic retinopathy (DR) screening. PATIENTS AND METHODS: Retrospective observational study of 5,764 insured diabetic patients undergoing telemedicine DR screening between May 2015 and April 2017 in an urban primary care setting. Patients underwent non-mydriatic fundus photography for telemedicine DR screening. The main outcome measure was the "capture rate." RESULTS: Of the patients studied, 31.7% were found to have any retinal pathology, and 20% were found to have DR. In the 11.8% percent of patients with sight-threatening retinopathy who were recommended to have a retinal examination, the capture rate was 81.9%. CONCLUSION: The authors' study demonstrated higher capture rate than has been previously reported, indicating that telemedicine DR screening in an urban, insured population may be a useful method for triaging high-risk patients without losing patients to follow-up.

Central serous retinopathy associated with topical oral corticosteroid use: a case report.

BACKGROUND: Oral topical corticosteroid gels are widely used in dental medicine. Case studies of central serous retinopathy have been reported following administration of corticosteroids, but none so far coinciding with the use of topical fluocinonide gel. This case report further contributes to the database of potential risks of corticosteroid use. CASE PRESENTATION: A 40-year-old South Asian woman presented with decreased vision, pigment epithelial detachments, and serous retinal detachments in both eyes 1 month after starting treatment with topical fluocinonide 0.05%, a topical oral corticosteroid gel. Her condition resolved 6 months after discontinuing the use of the steroid. CONCLUSIONS: To the best of our knowledge, this is the first case of idiopathic central serous retinopathy associated with the use of oral fluocinonide gel. Discontinuing the use of the steroid may result in resolution of the serous retinal detachment and improvement of visual symptoms. Patients and their doctors who prescribe this medication should be aware of this association.

Nonleaking cystoid macular edema in Cohen syndrome.

An 11-year-old girl with a history of neutropenia, developmental delay, hypotonia, and intellectual disability was diagnosed with Cohen syndrome after genetic testing discovered homozygous mutation in the VPS13B gene. She was referred to a retinal specialist with a chief complaint of decreased peripheral vision. On examination, decreased visual acuity, pigmentary changes, and nonleaking cystoid macular edema were present in both eyes.

Optic neuritis following diphtheria, tetanus, pertussis, and inactivated poliovirus combined vaccination: a case report.

BACKGROUND: Diphtheria, tetanus, pertussis, and inactivated poliovirus combined vaccine is widely used in young children as part of a series of immunizations before they start attending school. Case studies of demyelinating conditions following administration of diphtheria, tetanus, pertussis, and polio vaccine have been reported, but none so far resulting in optic neuritis. This report further contributes to the database of central nervous system demyelinating conditions affiliated with receipt of vaccines. CASE PRESENTATION: A previously healthy 27-year-old Hispanic man presented to an emergency department with headache, periorbital pressure, pain with ocular movements, and intermittent blurred vision that developed 1 day after administration of the diphtheria, tetanus, pertussis, and inactivated poliovirus combined vaccine. A diagnosis of optic neuritis was made via ophthalmic examination with fundus photography and automated Humphrey visual field analysis. His vision recovered following treatment with high-dose intravenously administered methylprednisolone followed by a tapered dose of orally administered prednisolone. CONCLUSIONS: Although the association between immunizations and the onset of central nervous system demyelinating conditions is well documented, this report, to the best of our knowledge, is the first case of optic neuritis following diphtheria, tetanus, pertussis, and inactivated poliovirus combined vaccination. Inclusion of this case report in the medical community will allow for broader understanding of possible conditions that may present shortly after receipt of vaccination.

PARACENTRAL ACUTE MIDDLE MACULOPATHY AFTER PREWORKOUT HAVOK INGESTION.

PURPOSE: To describe a case of transient, partial, central retinal artery occlusion with paracentral acute middle maculopathy optical coherence tomography presentation in a young healthy patient after ingestion of the synephrine-containing supplement, Havok. METHODS: Retrospective case report with fundus photography, fluorescein angiography, and optical coherence tomography. RESULTS: A 20-year-old man presented with severe acute vision loss in the right eye. Dilated examination demonstrated cherry red spot with surrounding edema in the macula. Optical coherence tomography showed hyperreflectivity in the middle retinal layer of the macula consistent with paracentral acute middle maculopathy. Fluorescein angiography showed delayed arteriovenous transit time consistent with a central retinal artery occlusion. Bloodwork to investigate a hypercoagulable state and vasculitis were negative. At 1-week follow-up, dilated examination demonstrated resolution of the cherry red spot. At 3 months, the patient's visual acuity was back to normal. Fluorescein angiography showed complete resolution of the retinal artery occlusion, but optical coherence tomography of the macula demonstrated mild, residual middle retina thinning consistent with chronic presentation of paracentral acute middle maculopathy. CONCLUSION: Because of synephrine's physiological and structural similarity to the vasoconstrictive compound ephedra, it is reasonable to suggest that there is potential health hazard in this performance-enhancing compound.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

DYNAMIC RETINA VESSEL COLOR CHANGE DURING OCULAR COMPRESSION IN SEVERE LIPEMIA RETINALIS.

PURPOSE: The aim of this study was to describe dynamic color change in retinal vessels from white to coral pink due to externally applied ocular pressure in a 6-week-old infant with lipemia retinalis secondary to type 1b familial hyperlipoproteinemia. METHODS: Fundus images and fluorescein angiogram were taken with RetCam3 camera. Color photographs of pooled blood were taken during phlebotomy. RESULTS: Genetic analysis revealed a rare genetic mutation in the APOC2 gene, a lipoprotein lipase activator. Intraocular pressure applied to the globe induced a color change in the retinal arteries from white to coral pink. Disruption in laminar flow leading to this change is described. CONCLUSION: This is the first report to attribute the retinal vessel color change to disrupted laminar flow and the intermixing of larger erythrocytes and smaller chylomicrons in a patient with lipemia retinalis. In addition, this is a rare example of congenital hyperlipidemia in the offspring of nonconsanguineous parents.

Reported Complications Following Laser Vitreolysis.

Importance: Use of laser vitreolysis for symptomatic floaters has increased in recent years, but prospective studies are not available and the complication profile is poorly understood. Objective: To analyze cases of complications following laser vitreolysis as voluntarily reported to the American Society of Retina Specialists Research and Safety in Therapeutics (ASRS ReST) Committee, an independent task force formed to monitor device-related and drug-related safety events. Design, Setting, and Participants: A retrospective assessment was performed of all cases of complications following laser vitreolysis that were voluntarily reported by practitioners throughout the United States to the ASRS ReST Committee from the first report on September 19, 2016, through March 16, 2017, the date of data analysis and manuscript writing. Main Outcomes and Measures: Complications reported to the ASRS ReST Committee following laser vitreolysis were analyzed by type to gain an understanding of the spectrum of potential complications. Results: A total of 16 complications following laser vitreolysis were reported in 15 patients by 7 US vitreoretinal specialists during the study period. Complications included elevated intraocular pressure leading to glaucoma; cataracts, including posterior capsule defects requiring cataract surgery; retinal tear; retinal detachment; retinal hemorrhages; scotomas; and an increased number of floaters. Conclusions and Relevance: This report presents a spectrum of complications reported to the ASRS ReST Committee across 6 months. The rate of complications cannot be determined because the denominator of total cases is unknown. Also, these findings cannot determine whether there is a causal association between these complications and laser vitreolysis. Prospective studies are warranted to better understand the efficacy of this procedure and the frequency of attendant complications. Until then, practitioners should be aware of the profile of potential complications to properly inform patients during the consent process. The ASRS ReST Committee will continue to monitor device-related and drug-related adverse events and encourages active surveillance and reporting by all physicians.

DIDANOSINE RETINAL TOXICITY.

PURPOSE: To report nine new cases of retinal degeneration secondary to didanosine toxicity and to summarize the previously reported cases in the literature. METHODS: This was a multicenter, retrospective, observational case study from seven institutions. Medical records of patients who demonstrated well-demarcated severe midperipheral chorioretinal degeneration and who were previously treated with didanosine therapy were collected and the following information was reviewed: age, gender, medical history, detailed medication history including current and previous antiretroviral use, ocular and retinal examination findings, and multimodal imaging findings with optical coherence tomography, fundus photography, wide-field fundus autofluorescence, and wide-field fluorescein angiography. When available, findings with electrophysiology testing and automated perimetry were also collected and reviewed. A literature review was also performed to collect all reported cases of chorioretinal degeneration secondary to didanosine toxicity. RESULTS: Nine patients were identified who had findings consistent with peripheral retinal toxicity secondary to didanosine use. Eight of the 9 patients were men, and the median age was 54 years at the time of presentation (mean: 55 years, range, 42-71 years). Snellen distance acuity ranged from 20/20 to 20/32. At least three of the cases in the series demonstrated progression of the peripheral retinal pigment epithelium and photoreceptor atrophy despite didanosine cessation. A review of the literature revealed 10 additional cases of didanosine toxicity. Seven of the 10 cases were in men (70%), and the average age was 26 years with a wide range (2-54 years). Chorioretinal findings were very similar to this cohort. CONCLUSION: Herein, we report the largest series of nine cases of peripheral chorioretinal degeneration secondary to didanosine toxicity in adults. When combined with the cases in the literature, 19 cases of didanosine toxicity, 4 of which occurred in children, were collected and analyzed. Three of the new cases presented showed clear progression of degeneration despite didanosine cessation. Newer nucleoside reverse transcriptase inhibitors may potentiate mitochondrial DNA damage and lead to continued chorioretinal degeneration.

Bilateral frosted branch angiitis as the presenting sign of antiphospholipid antibody syndrome.

BACKGROUND: "Frosted branch retinal angiitis" is an encompassing term for a rare, typically bilateral diffuse retinal periphlebitis that may occur in a number of varying conditions. To our knowledge, we report the first case of frosted branch angiitis as the presenting sign of antiphospholipid antibody syndrome in a 28-year-old woman. FINDINGS: This study is a retrospective case report and literature review. Serial fundus photos, fluorescein angiogram, and ocular coherence tomography taken were before and after treatment, showing resolution of diffuse retinal perivascular sheathing and macular edema along with marked improvement in visual acuity 4 months after the treatment with corticosteroids. CONCLUSIONS: Frosted branch angiitis can be seen in association with antiphospholipid antibody syndrome. Prompt recognition and treatment with corticosteroids may result in good visual prognosis, and long-term immunosuppression and additional anticoagulation may be beneficial to prevent recurrence.
