RESUMEN

Importance: Anti-vascular endothelial growth factor (VEGF) intravitreal injections, a mainstay of treatment for many retinal diseases to optimize visual outcomes, have been included in prior authorization (PA) initiatives. However, if clinicians are extremely accurate in their use of anti-VEGF medications, such administrative burdens may need reconsideration. Objective: To quantify PA for anti-VEGF medications (aflibercept, ranibizumab, and bevacizumab) that were approved and determine associated administrative burdens experienced by retina practices. Design, Setting, and Participants: Prospective multicenter quality improvement study conducted from January 2022 through June 2022, and participants were 9 private retina practices across the US. Main Outcomes and Measures: Overall rate of approval of PA requests, reasons for requesting PA, and overall rate of delay of care resulting from PA procedures. Results: In total, 2365 PA requests were recorded, 2225 of which met inclusion criteria. Overall, 2140 (96.2%) requests were approved. The most common reason for requesting PA, at 64% (1423 of 2225 requests), was reauthorization for a previously utilized medication. Of the 2140 approvals, 59.6% (1277) resulted in a delay in care greater than 24 hours, and 40% (863) were given on the date of service. In a granular analysis of a subset of delayed approvals, 23.9% (173 of 725) were approved within 1 day, 15.9% (115 of 725) were approved within 2 to 3 days, 21.5% (156 of 725) were approved within 4 to 7 days, 26.3% (191 of 725) were approved within 8 to 31 days, and 12.4% (90 of 725) were approved within more than 31 days. Overall, PA denial for step therapy was 2.9% (65 of 2225) of requests and uncovered diagnoses was 0.9% (20 of 2225) of requests. The median staff time spent to obtain a single PA was 100 (range, 0-200) minutes. Conclusions and Relevance: In this study, PA requests were almost always approved but led to a delay in patient care in most patients. The current study suggests that the PA process may not be effective for retina specialists if these results can be generalized to other practices in the US and if less burdensome and less costly approaches could result in similar approval rates. Potential short-term solutions may include eliminating the PA process for bevacizumab and reauthorizations for established patients.

RESUMEN

PURPOSE: There is strong evidence that genetic factors influence retinopathy of prematurity (ROP), a neovascular eye disease. It has been previously suggested that polymorphisms in the genes involved in ß-adrenergic receptor (ADRß) pathways could protect against ROP. Antagonists for the ADRß are actively tested in clinical trials for ROP treatment, but not without controversy and safety concerns. This study was designed to assess whether genetic variations in components of the ADRß signaling pathways associate with risk of developing ROP. DESIGN: An observational case-control targeted genetic analysis. METHODS: A study was carried out in premature participants with (n = 30) or without (n = 34) ROP and full-term controls (n = 20), who were divided into a discovery cohort and a validation cohort. ROP was defined using International Classification of Retinopathy of Prematurity criteria (ICROP). Targeted sequencing of 20 genes in the ADRß pathways was performed in the discovery cohort. Polymerase chain reaction (PCR)/restriction enzyme analysis for some of the discovered ROP-associated variants was performed for validation of the results using the validation cohort. RESULTS: The discovery cohort revealed 543 bi-allelic variants within 20 genes of the ADRß pathways. Ten single-nucleotide variants (SNVs) in 5 genes including protein kinase A regulatory subunit 1α (PRKAR1A), rap guanine exchange factor 3 (RAPGEF3), adenylyl cyclase 4 (ADCY4), ADCY7, and ADCY9 were associated with ROP (P < .05). The most significant SNV was found in PRKAR1A (P = .001). Multiple variants located in the 3'-untranslated region (3'UTR) of RAPGEF3 were also associated with ROP (P < .05). PCR/restriction enzyme analysis of the 3'UTR of RAPGEF3 methodologically validated these findings. CONCLUSION: SNVs in PRKAR1A may represent protective factors whereas SNVs in RAPGEF3 may represent risk factors for ROP. PRKAR1α has previously been implicated in retinal vascular development whereas the RAPGEF3 product has a role in the maintenance of vascular barrier function, 2 processes important in ROP. Multicenter validation of these newly discovered risk factors could lead to valuable tools for predicting and preventing the development of severe ROP.

RESUMEN

PURPOSE: To describe two cases of catastrophic, bilateral retinal vascular occlusion after intravitreal (IVT) bevacizumab injection. METHODS: Case series. Main outcome measures included clinical and fluorescein angiography findings. RESULTS: Case 1-A 65-year-old woman with calcinosis, Raynaud phenomenon, esophageal dysfunction, sclerodactyly, and telangiectasis syndrome developed acute, severe, bilateral visual loss 2 weeks after bilateral IVT bevacizumab injection for proliferative diabetic retinopathy. Examination and fluorescein angiography revealed moderate anterior chamber inflammation, bilateral perivascular retinal hemorrhages, and near total retinal vascular occlusion. Extensive testing revealed moderately elevated anti-B2 glycoprotein (antiphospholipid) antibodies. Case 2-An 85-year-old man with polymyalgia rheumatica and left eye exudative age-related macular degeneration experienced severe, bilateral, sequential visual loss in the left eye and then right eye approximately 3 weeks after IVT bevacizumab left eye injection. Examination revealed bilateral panuveitis, diffuse perivascular exudates, and intraretinal hemorrhages. Fluorescein angiography showed diffuse venous leakage. Extensive testing revealed an elevated antinuclear antibody and mildly elevated anticardiolipin antibody. CONCLUSION: Patients with underlying retinal vascular vulnerabilities may be at increased risk of catastrophic, bilateral retinal vascular occlusion after treatment with IVT bevacizumab. The moderate-to-severe intraocular inflammation in both cases and the contralateral involvement after unilateral IVT injection in Case 2 suggest a possible delayed immune-mediated mechanism.

RESUMEN

PURPOSE: To report a case of presumed intraretinal tuberculosis evaluated with optical coherence tomography angiography. METHODS: Case report. RESULTS: A 61-year-old woman recently immigrated from China presented with round yellow-white retinal lesions in the left eye. The lesions were evaluated with multimodal imaging, including optical coherence tomography angiography. Subsequent serologic testing revealed a positive QuantiFERON-TB Gold test, whereas workup for other entities was negative. The patient was diagnosed with presumed intraretinal tuberculosis. She was started on systemic antitubercular therapy and the lesions regressed. The regression was documented with optical coherence tomography angiography. CONCLUSION: Case reports of primary intraretinal tuberculosis are uncommon. To the best of our knowledge, this is the first case to demonstrate optical coherence tomography angiography findings of presumed intraretinal tuberculosis.

RESUMEN

PURPOSE: To report an increasingly prevalent fundoscopic manifestation of syphilitic uveitis. METHODS: Case report of a patient with acute retinal necrosis secondary to syphilis. RESULTS: A 48-year-old man presented with decreased vision, anterior segment inflammation, and a wedge-shaped retinal lesion in the superior periphery, with a diaphanous leading edge extending down toward the superior arcade. The patient was HIV+ and poorly compliant with therapy. The top three differential diagnoses were herpetic necrotizing retinitis, syphilis, and lymphoma. An extensive lab workup was positive for syphilis. The patient was treated with IV penicillin G and demonstrated improvement in visual acuity and examination. CONCLUSION: There have been an increasing number of reports of syphilis patients, especially in the population of men who have sex with men, who present with fundus findings similar to acute retinal necrosis. These findings include a characteristic ground glass, translucent appearance of unifocal or multifocal lesions, primarily affecting the inner retina and sometimes associated with co-localizing occlusive vasculitis. Treatment with IV penicillin G is warranted and has demonstrated good visual recovery.

RESUMEN

PURPOSE: To assess the impact of submacular fluid (SMF) after pneumatic retinopexy for primary rhegmatogenous retinal detachment repair. METHODS: Retrospective review of consecutive patients treated with pneumatic retinopexy for primary rhegmatogenous retinal detachment repair. 387 eyes (374 patients) were included, of which 166 underwent optical coherence tomography imaging after successful pneumatic retinopexy. Foveal-centered optical coherence tomography scans were reviewed. RESULTS: SMF occurred in 59 eyes (35.5%) and was associated with macular detachment ( P ≤ 0.001) and phakic lens status ( P = 0.007). Submacular fluid resolved over an average of 9.39 months and was associated with worse preprocedure best-corrected visual acuity and delayed visual recovery. The mean final best-corrected visual acuity was 0.277 logarithm of the minimum angle of resolution (20/40) in eyes with SMF and 0.162 logarithm of the minimum angle of resolution (20/30) in those without SMF ( P < 0.001). Submacular fluid was associated with discontinuity of the interdigitation zone ( P = 0.003), ellipsoid zone ( P = 0.005), and external limiting membrane ( P ≤ 0.001) after SMF resolution. Ellipsoid zone discontinuity was associated with worse visual prognosis ( P = 0.009). CONCLUSION: Trace SMF detected by optical coherence tomography is common after successful pneumatic retinopexy and resulted in delayed visual recovery and increased rates of outer retinal discontinuity after SMF resorption, although the final difference in best-corrected visual acuity in those with and without SMF was minimal.

RESUMEN

PURPOSE: To investigate the clinical and anatomic characteristics of soccer ball-induced posterior segment injuries in the era of modern multi-modal imaging. METHODS: Retrospective case series of patients with soccer ball injury and diagnostic imaging from 2007 to 2020 at a single vitreoretinal practice. RESULTS: Eight patients met inclusion criteria. Fundus photographs (FP) and optical coherence tomography (OCT) were obtained in eight patients, fundus autofluorescence (FAF) in five patients, fluorescein angiography (FA) in three patients, and en-face OCT and OCT-Angiography (OCT-A) were obtained in two patients each. FA and FAF identified traumatic pigment epitheliopathy secondary to commotio. Increased hypo-autofluorescence was associated with shallow, peripheral retinal detachment on FAF. OCT of the macula displayed outer retinal changes associated with commotio, and offered insight into the acute and subacute changes of traumatic macular hole formation. A patient displayed foveal hyper-reflectivity in the shape of an hourglass with retinal cyst at the level of the external limiting membrane (ELM) as seen on OCT and En-face OCT. A patient with commotio involving the macula lacked microvascular changes on OCT-A. CONCLUSION: OCT, FA, and FAF imaging may aid in the work-up and management of the soccer ball-related posterior segment injuries.

RESUMEN

Purpose: To report a case of central serous chorioretinopathy (CSC) associated with Adderall (dextroamphetamine-amphetamine) and topical steroid use. Observations: A 34-year-old man presented for evaluation of a "cloud" in his vision for three months. He was taking Adderall for attention deficit hyperactivity disorder and mometasone 0.1% topical cream for eczema. He was found to have subretinal fluid in the left eye consistent with CSC. The subretinal fluid persisted despite cessation of the steroid cream but resolved after cessation of the Adderall. The subretinal fluid returned when the patient restarted Adderall and again resolved after he stopped it for a second time. Conclusions: Though we cannot prove causality, the course of events was suggestive of a direct relationship between Adderall use and CSC in this patient, with exogenous steroid as a possible modifying factor.

RESUMEN

Purpose: This work analyzes data from a series of surveys developed by the American Society of Retina Specialists (ASRS) that assesses the impact of COVID-19 on physicians, their practices, and their patients. Methods: Five surveys were sent by the ASRS between March and July 2020 to more than 2600 US and international retina specialists. Data and trends from these surveys were analyzed. Results: Most responding retina specialists (87%-95% in the United States and internationally) reported having no known COVID-related symptoms despite reported limitations in personal protective equipment. Clinic volumes globally were drastically reduced in March 2020 with only partial recovery through July 2020, which was slower internationally than in the United States. Practices were compelled to reduce staff and physician employment levels. Most respondents estimated some degree of delay in patient treatment with corresponding declines in vision and/or anatomy that were attributed most frequently to patients' fears of the pandemic and least frequently to office unavailability. Conclusions: The reported impact of COVID-19 on retina specialists, their practices, and their patients has been substantial. Although retina specialists were quickly resilient in optimizing delivery of patient care in a manner safe for patients and providers, the reduction in clinic volume has been devastating in the United States and internationally, with negative impacts on patient outcomes, reductions in practices' volume and employment, and risk to practices' financial health. Future studies will be required to quantify losses associated with these unprecedented and ongoing circumstances caused by the pandemic.

RESUMEN

This is a case report detailing a pars plana vitrectomy and resection of a retinal capillary hemangioblastoma in a 19-year-old female with a history of von Hippel-Lindau syndrome with secondary retinal detachment and sub-retinal exudates limiting her vision. Intraoperatively, long duration endolaser and generous endodiathermy applied to the feeder vessels are essential to minimize bleeding. Complete and careful resection of the lesion and installation of a silicone oil tamponade are recommended. This technique can allow for retinal reattachment and improvement in visual acuity in advanced cases of secondary retinal detachment.

RESUMEN

Purpose: To report novel mutations in the FZD4 and LRP5 genes, associated with familial exudative vitreoretinopathy (FEVR), and to correlate with clinical features of 7 FEVR patients.Methods: In this retrospective case series, 7 patients who had undergone genetic panel testing and carried a diagnosis of FEVR were identified. Comprehensive ophthalmic examination and direct DNA sequencing of FEVR-associated genes were performed in all patients. Identified sequence variants were analyzed in silico.Results: Eight mutations were identified amongst the 7 patients, that included 4 FZD4 mutations and 4 LRP5 mutations. Four novel mutations were identified, two in FZD4 (c.615delC, p.Y206MfsX34) and (c.964A>T, p.I322F), and two in LRP5 (c.2585A>T, p.D862V) and (c.1412 + 1 G > A, splice donor). A broad phenotypic spectrum was noted and no clear genotypic-phenotypic correlation was observed.Conclusion: These findings expand the mutation spectrum of FZD4 and LRP5.

RESUMEN

Purpose: Intravitreal injection is the most frequently performed eye procedure in the world and is an essential component in the management of sight-threating retinal diseases and conditions. Given the seriousness and range of diseases treated and the risks of the procedure, retina specialists must weigh the pros and cons of each individual treatment. Complexities guiding injection treatment are multifaceted and involve patient-history review, careful examination, diagnostic testing selection and interpretation, customized medical decision-making, and follow-up considerations. Methods: This article by the Intravitreal Injection Task Force Committee of the American Society of Retina Specialists documents the intricacies and necessary components of the intravitreal injection procedure. Results: By expert consensus, the task force further recommends ancillary services and decision-making that may accompany intravitreal injection visits, when appropriate, to monitor response to treatment, adjust treatment, and manage additional considerations in the same or fellow eye. Conclusions: Retina specialists can optimize safety and therapeutic outcomes with individualized consideration and customization of intravitreal injection treatment for each patient.

RESUMEN

PURPOSE: To describe the appearance of concentric, fingerprint-like waves within the Henle fiber layer (HFL) using en face optical coherence tomography in patients with tractional pathologies of the retina. METHODS: Retrospective analysis of six eyes of six patients imaged by optical coherence tomography with volumetric slabs positioned at the level of the HFL. RESULTS: Optical coherence tomography data from six patients with tractional vitreoretinal pathology were reviewed. Concentric, fingerprint-like microwaves were visualized through en face optical coherence tomography in all six study eyes at the level of the HFL. This finding resembled the finding of HFL waves previously noted histopathologically from force exerted on this layer. CONCLUSION: In retinal pathologies in which specific physical forces act on the retina, volumetric optical coherence tomography may permit visualization of en face concentric, fingerprint-like hyperreflective rings within the HFL. This "fingerprint sign" may represent a biomechanical consequence of traction on the retina and allow clinical decision making based on improved recognition of the existence of such traction.

RESUMEN

PURPOSE: To describe the multimodal imaging (MMI) findings and clinical course of a case of Multiple Evanescent White Dot Syndrome (MEWDS) following immunization with inactivated intra-dermal influenza virus, and to explore whether similarities exist with other, previously reported cases. OBSERVATIONS: A 34-year-old Caucasian man presented with unilateral onset of para-central scotomata, photopsias, and dyschromatopsia two weeks after administration of an influenza vaccine. Clinical examination and MMI were indicative of MEWDS. The patient's MMI abnormalities and symptoms resolved spontaneously after four weeks. CONCLUSION AND IMPORTANCE: This is the first reported case of MMI of post-influenza vaccination-associated MEWDS. Comparison with eight previously reported cases of MEWDS following various immunizations revealed that subjects tended to be healthy, young to middle age women with a median time to onset of two weeks. Vision tended to recover spontaneously over one to three months.

RESUMEN

PURPOSE: To evaluate the efficacy, safety, and injection frequency of vascular endothelial growth factor (VEGF) antagonists in the treatment of macular edema secondary to retinal vein occlusion (RVO) in clinical practice. PATIENTS AND METHODS: A multicenter retrospective study of the medical records of 165 patients (95 branch RVO, 70 central RVO) treated with at least three anti-VEGF injections in the study eye was conducted. Available data collected for at least 6 months after the first injection included Snellen best-corrected visual acuity (BCVA), central retinal thickness (CRT) by time-domain optical coherence tomography (TD-OCT) or spectral-domain optical coherence tomography (SD-OCT), anti-VEGF injections, other treatments/procedures for RVO, and adverse events. RESULTS: At baseline prior to anti-VEGF treatment, mean BCVA was 20/80 Snellen equivalent and mean CRT was 499 µm. Mean number of anti-VEGF injections received was 7.1 during the first year, 5.4 during the second year, and 5.9 during the third year; 51.3% (842/1,641) of injections were ranibizumab, 44.1% (724/1,641) were bevacizumab, and 4.6% (75/1,641) were aflibercept. One in five patients received concomitant focal laser treatment. The percentage of patients achieving both BCVA of 20/40 or better and CRT ≤250 µm on TD-OCT or ≤300 µm on SD-OCT at the same visit (primary endpoint) was 26.1% (30/115) after the first anti-VEGF injection and ranged from 20.0% (7/35) to 36.7% (11/30) after the first 16 injections. After each anti-VEGF injection from the 1st to the 16th, <60% of patients achieved 20/40 or better BCVA and ≤70% of patients achieved CRT ≤250 µm on TD-OCT or ≤300 µm on SD-OCT. The most common treatment-related adverse event was blurry or cloudy vision. CONCLUSION: In this real-world study, a mean of five to seven anti-VEGF injections was administered yearly, and the response to anti-VEGF therapy was suboptimal in many patients. Anti-VEGF therapy was well tolerated.

RESUMEN

PURPOSE: Diffuse unilateral subacute neuroretinitis (DUSN) is often a challenging diagnosis to make. We present a DUSN case with its multimodal imaging to aid in the diagnosis, emphasizing the observations on optical coherence tomography angiography (OCTA). OBSERVATIONS: The evolution of a DUSN case is presented. Fundus photography and OCTA aided in the identification of the nematode. CONCLUSIONS AND IMPORTANCE: DUSN is a difficult diagnosis to establish. We report the first case to our knowledge in which OCTA aided in the diagnosis of DUSN.

RESUMEN

PURPOSE: To evaluate the efficacy, safety, and injection frequency of vascular endothelial growth factor (VEGF) inhibitors as used in clinical practice for the treatment of diabetic macular edema. METHODS: Multicenter (10 sites), retrospective chart review in patients (n=156) who received ≥3 anti-VEGF injections. Data collected for ≥6 months after the first injection included Snellen best-corrected visual acuity (BCVA) and central retinal thickness (CRT) by time-domain or spectral-domain optical coherence tomography (TD-OCT or SD-OCT). RESULTS: Mean number of anti-VEGF injections (627 bevacizumab, 594 ranibizumab, 1 aflibercept) was 5.8 (year 1), 5.0 (year 2), and 3.4 (year 3). Percentage of patients with BCVA of 20/40 or better and CRT ≤250 µm on TD-OCT or ≤300 µm on SD-OCT at the same visit (primary endpoint) ranged from 16.4% to 38.9% after the first 10 injections; 51.9%-62.3% achieved ≥20/40 BCVA and 26.2%-48.0% met CRT criteria. Therapy was well tolerated with 19 treatment-related adverse events (all ocular) reported. CONCLUSION: Anti-VEGF injections were administered less frequently and were less effective than those in the ranibizumab registration trials. After each of the first 9 injections, <25% of patients achieved both BCVA of 20/40 or better and a dry macula. A substantial proportion of patients are suboptimal responders to anti-VEGF therapy; these patients may be candidates for other therapies, including intravitreal corticosteroid and laser therapy.

RESUMEN

PURPOSE: To expand understanding of presentation, diagnosis, and outcomes of hemorrhagic occlusive retinal vasculitis (HORV). DESIGN: Retrospective case series. PARTICIPANTS: Thirty-six eyes of 23 patients. METHODS: The American Society of Cataract and Refractive Surgery (ASCRS) and the American Society of Retina Specialists (ASRS) formed a joint task force to define clinical characteristics of HORV and to study its prevalence, cause, treatment, and outcomes. An online registry was established on both societies' web sites. Surveys were e-mailed to members of both societies soliciting cases of suspected HORV. A literature search was performed to uncover additional cases. MAIN OUTCOME MEASURES: Historical data including intraoperative characteristics, images, treatment regimens, and visual and anatomic outcomes. RESULTS: Characteristic findings of HORV included unremarkable postoperative day 1 undilated examination, delayed-onset painless vision loss, mild anterior chamber and vitreous inflammation, sectoral retinal hemorrhages in areas of ischemia, and predilection for venules and peripheral involvement. Based on predetermined diagnostic criteria, 36 eyes of 23 patients were diagnosed with HORV. All eyes received intraocular vancomycin via intracameral bolus (33/36), via intravitreal injection (1/36), or through the irrigation bottle (2/36). Patients sought treatment with HORV 1 to 21 days after surgery or intravitreal injection. Visual results usually were poor: 22 of 36 eyes (61%) had 20/200 or worse visual acuity and 8 of 36 eyes (22%) had no light perception (NLP). Neovascular glaucoma developed in 20 of 36 eyes (56%). Seven eyes received additional intravitreal vancomycin after surgery; 5 of these 7 eyes had NLP visual acuity at the most recent examination. Three eyes received intravitreal corticosteroids and had final visual acuities of 20/40, 20/70, and hand movements. CONCLUSIONS: Hemorrhagic occlusive retinal vasculitis is a rare, potentially devastating condition that can develop after cataract surgery or intraocular injection. All cases in this series were associated with intraocular vancomycin. Disease course and findings suggest that HORV is caused by a delayed hypersensitivity reaction to vancomycin. Early treatment with corticosteroids likely is beneficial. Subsequently, anti-vascular endothelial growth factor injections and panretinal photocoagulation are important to prevent neovascular glaucoma, a common complication. Avoidance of additional intravitreal vancomycin is recommended if HORV is suspected.

RESUMEN

PURPOSE: To describe the ocular findings and subsequent workup of a 21-year-old woman with previously undiagnosed Fanconi anemia. METHODS: Observational case report and literature review. RESULTS: A 21-year-old healthy woman presented with bilateral retinal hemorrhages, telangiectasia, and severe ischemia with vascular leak. Systemic workup revealed anemia and thrombocytopenia. A diepoxybutane chromosomal breakage test confirmed the diagnosis of Fanconi anemia. CONCLUSION: Ocular complications are common in patients with Fanconi anemia and may be the presenting manifestation of the disease.
