Endoscopic enucleation and clinicopathologic correlation of a small choroidal melanoma hiding massive extrascleral extension.

Purpose: To report the unusual case of a previously stable choroidal nevus, closely followed for over 15 years, which underwent malignant transformation into small choroidal melanoma with massive extrascleral extension. Observations: A 67-year-old Caucasian female was referred to the Stanford Ocular Oncology Service with concern for malignant transformation of a previously stable choroidal nevus in her left eye. Her funduscopic examination demonstrated a dome-shaped choroidal lesion with overlying associated lipofuscin and subretinal fluid, consistent with a diagnosis of small choroidal melanoma. By B-scan ultrasonography, the lesion measured 8.0 × 6.0 mm in base and 2.1 mm in thickness. B-scan ultrasonography also disclosed an associated retroscleral mass, which appeared contiguous with the intraocular melanoma and was confirmed on subsequent orbital magnetic resonance imaging. A decision was made to proceed with enucleation. Under direct endoscopic visualization, the globe and extrascleral mass were fully isolated, mobilized, and removed in toto. At 24 months post-enucleation, the patient remains disease-free without evidence of systemic metastasis or local recurrence. Conclusions/importance: This case describes a small choroidal melanoma hiding massive extrascleral extension, underscoring the value of B-scan ultrasonography. This case also describes the unique management of choroidal melanoma with extrascleral extension using endoscopic enucleation. Performing enucleation under direct endoscopic visualization ensures complete resection and prevents inadvertent transection of the extrascleral component.

Fall risk in patients with pseudophakic monovision.

OBJECTIVE: Vision changes can precipitate falls in the elderly resulting in significant morbidity and mortality. We hypothesized that pseudophakic monovision and ensuing anisometropia and aniseikonia impact elderly fall risk. This study assessed fall risk in patients with pseudophakic monovision, pseudophakic single vision distance (classic cataract surgery), and cataracts with no surgery. DESIGN: Retrospective single-institution cohort study PARTICIPANTS: Patients with bilateral cataracts diagnosed at 60 years of age or older who underwent bilateral cataract surgery (monovision or single vision distance) or did not undergo any cataract surgery (n = 13 385). Patients with unilateral surgery or a fall prior to cataract diagnosis were excluded. METHODS: Data were obtained from the Stanford Research Repository. Time-to-fall analysis was performed across all 3 groups. Primary outcome was hazard ratio (HR) for fall after second eye cataract surgery or after bilateral cataract diagnosis. RESULTS: Of 13 385 patients (241 pseudophakic monovision, 2809 pseudophakic single vision, 10 335 no surgery), 850 fell after cataract diagnosis. Pseudophakic monovision was not associated with fall risk after controlling for age, sex, and myopia. Pseudophakic single-vision patients had a decreased time to fall compared with no-surgery patients (log rank, p < 0.001). Older age at cataract diagnosis (HR =1.05, 95% confidence interval [CI] 1.04-1.06, p < 0.001) or at time of surgery (HR = 1.05, 95% CI 1.03-1.07, p < 0.001) increased fall risk, as did female sex (HR = 1.29, 95% CI 1.10-1.51, p = 0.002) and preexisting myopia (HR = 1.31, 95% CI 1.01-1.71, p = 0.046) among nonsurgical patients. CONCLUSIONS: Pseudophakic monovision did not impact fall risk, but pseudophakic single vision may increase falls compared with patients without cataract surgery.

A 48-YEAR-OLD CAUCASIAN MAN WITH UNILATERAL "SMUDGE" IN INFERIOR VISUAL FIELD.

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.

CRB1-associated retinal dystrophy presenting as self-resolving opsoclonus and posterior uveitis.

PURPOSE: To describe the unusual case of inflammatory CRB1-associated retinal dystrophy that initially presented with self-resolving opsoclonus. OBSERVATIONS: We report the case of a now 2-year-old female who developed opsoclonus without myoclonus at the age of 4 months. An extensive workup for neuroblastoma and other systemic diseases was unremarkable, and all unusual eye movements self-resolved at age 10 months. Twenty-one months after initial presentation, she began having reduced visual behaviors, and comprehensive ophthalmic exam at that time revealed recurrent saccadic intrusions as well as severe, chronic retinal inflammation and dystrophic changes. An extensive infectious and inflammatory workup was negative. Genetic sequencing revealed two variants in CRB1: a heterozygous missense mutation and a heterozygous novel deletion involving exon 12. The patient was treated with monthly infliximab and methylprednisolone infusions with improvement in her optic disc and macular capillary leakage. The patient's 8-month-old sister also harbored the same variants in CRB1 and had early signs of retinal dystrophy and peripheral vascular leakage on exam. CONCLUSION: Saccadic intrusions may be the first sign of a retinal dystrophy, and infants and children with this presentation should undergo a complete eye exam. We further highlight the link between CRB1-associated retinal dystrophy and inflammation, and how systemic steroids and tumor necrosis factor alpha (TNF-α) inhibitors may be effective therapies. Finally, we report a novel deletion in CRB1 that is likely highly penetrant.

Trends in Leadership and Award Recognition Among Women in the American Society of Retina Specialists.

Purpose: This work evaluates trends in achievement of women in the retina field, through an analysis of gender representation in the American Society of Retina Specialists (ASRS). Methods: This retrospective, longitudinal study spans 1983 to 2020. Historical data classified by male or female gender were collected from ASRS's overall membership, board of directors and officers, and recipients of the 4 society awards. The proportion of each benchmark held by women was compared with prior decades since the founding of ASRS using the Fisher's exact test. Results: Women's representation increased from 11% of ASRS members in 2007 to 19.7% in 2020. From 2010 to 2019, women received a higher proportion of society awards (21.1%) compared with membership prior to the start of that decade. In 2020, women were proportionally well represented in board of director positions (21.9%) and held a significantly higher proportion of board positions than in the period 1983 to 1989 (P = .02). From 1983 to 2020, women held 4.3% (1 of 23) of presidencies. Conclusions: Although the number of women in retina is increasing, women remain underrepresented in the leadership of ASRS. Interventions to increase exposure to female mentorship and improve childcare benefits are warranted to engage female ophthalmology trainees in retina and ultimately society leadership.

Statins and the progression of age-related macular degeneration in the United States.

PURPOSE: To study the effect of statin exposure on the progression from non-exudative to exudative age-related macular degeneration (AMD). METHODS: Retrospective cohort study of commercially insured patients diagnosed with non-exudative AMD (n = 231,888) from 2007 to 2015. Time-to-event analysis of the association between exposure to lipid-lowering medications and time from non-exudative AMD to exudative AMD diagnosis was conducted. Outcome measures included progression to exudative AMD, indicated by diagnosis codes for exudative AMD or procedural codes for intravitreal injections. RESULTS: In the year before and after first AMD diagnosis, 11,330 patients were continuously prescribed lipid-lowering medications and 31,627 patients did not take any lipid-lowering medication. Of those taking statins, 21 (1.6%) patients were on very-high-dose lipophilic statins, 644 (47.6%) on high-dose lipophilic statins, and 689 (50.9%) on low-dose lipophilic statins. We found no statistically significant relationship between exposure to low (HR 0.89, 95% CI 0.83 to 1.38) or high-dose lipophilic statins (HR 1.12, 95% CI 0.86 to 1.45) and progression to exudative AMD. No patients taking very-high-dose lipophilic statins converted from non-exudative to exudative AMD, though this difference was not statistically significant due to the subgroup size (p = .23, log-rank test). CONCLUSIONS: No statistically significant relationship was found between statin exposure and risk of AMD progression. Interestingly, no patients taking very-high-dose lipophilic statins progressed to exudative AMD, a finding that warrants further exploration.

Serous retinal detachment as a presenting sign of acute lymphoblastic leukemia: A case report and literature review.

PURPOSE: To describe a unique case of unilateral serous retinal detachment as the presenting sign of B-cell acute lymphoblastic leukemia (ALL). OBSERVATIONS: A 74 year old woman presented with right eye blurry vision and was found to have an underlying serous retinal detachment, along with cotton wool spots, inner retinal hemorrhages, and retinal pigment epithelial changes throughout her bilateral fundi. Fluorescein angiography demonstrated bilateral vasculitis and ultrasonography revealed asymmetric thickening and enhancement of the affected eyes' choroid. This prompted a systemic lab workup and results were suspicious for an underlying hematologic malignancy. The patient was admitted to the hospital for bone marrow biopsy confirming B-cell ALL, underwent intensive intravenous and intrathecal chemotherapy, and was discharged one month later. Follow up appointment in the ophthalmology clinic demonstrated functional and anatomic improvement in the serous retinal detachment and choroidal thickening suggestive of infiltration in her right eye. CONCLUSIONS: SRDs are an uncommon ocular manifestation of leukemia, and even less common as a presenting sign of the disease. A comprehensive literature review demonstrated 11 other cases reported worldwide. We present the first such case with additional findings of leukemic retinopathy, optic nerve and choroidal infiltration, and vasculitis, as well as a complete library of ophthalmic imaging from the patient's initial presentation. IMPORTANCE: A new diagnosis of serous retinal detachment(s) without any obvious cause should raise suspicion for leukemia and prompt further workup. Early recognition of this hematologic malignancy is crucial for prompt initiation of life-saving therapy.

Comparison between wide-field digital imaging system and the red reflex test for universal newborn eye screening in Brazil.

PURPOSE: To compare neonatal eye screening using the red reflex test (RRT) versus the wide-field digital imaging (WFDI) system. METHODS: Prospective cohort study. Newborns (n = 380, 760 eyes) in the Maternity Ward of Irmandade Santa Casa de Misericórdia de São Paulo hospital from May to July 2014 underwent RRT by a paediatrician and WFDI performed by the authors. Wide-field digital imaging (WFDI) images were analysed by the authors. Validity of the paediatrician's RRT was assessed by unweighted kappa [κ] statistic, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). RESULTS: While WFDI showed abnormalities in 130 eyes (17.1%), RRT was only abnormal in 13 eyes (1.7%). Wide-field digital imaging (WFDI) detected treatable retina pathology that RRT missed including hyphema, CMV retinitis, FEVR and a vitreous haemorrhage. The sensitivity of the paediatrician's RRT to detect abnormalities was poor at 0.77% (95% confidence interval, CI, 0.02%-4.21%) with a PPV of only 7.69% (95% CI, 1.08%-38.85%). Overall, there was no agreement between screening modalities (κ = -0.02, 95% CI, -0.05 to 0.01). The number needed to screen to detect ocular abnormalities using WFDI was 5.9 newborns and to detect treatable abnormalities was 76 newborns. CONCLUSION: While RRT detects gross abnormalities that preclude visualization of the retina (i.e. media opacities and very large tumours), only WFDI consistently detects subtle treatable retina and optic nerve pathology. With a higher sensitivity than the current gold standard, universal WFDI allows for early detection and management of potentially blinding ophthalmic disease missed by RRT.

Key factors in a rigorous longitudinal image-based assessment of retinopathy of prematurity.

To describe a database of longitudinally graded telemedicine retinal images to be used as a comparator for future studies assessing grader recall bias and ability to detect typical progression (e.g. International Classification of Retinopathy of Prematurity (ICROP) stages) as well as incremental changes in retinopathy of prematurity (ROP). Cohort comprised of retinal images from 84 eyes of 42 patients who were sequentially screened for ROP over 6 consecutive weeks in a telemedicine program and then followed to vascular maturation or treatment, and then disease stabilization. De-identified retinal images across the 6 weekly exams (2520 total images) were graded by an ROP expert based on whether ROP had improved, worsened, or stayed the same compared to the prior week's images, corresponding to an overall clinical "gestalt" score. Subsequently, we examined which parameters might have influenced the examiner's ability to detect longitudinal change; images were graded by the same ROP expert by image view (central, inferior, nasal, superior, temporal) and by retinal components (vascular tortuosity, vascular dilation, stage, hemorrhage, vessel growth), again determining if each particular retinal component or ROP in each image view had improved, worsened, or stayed the same compared to the prior week's images. Agreement between gestalt scores and view, component, and component by view scores was assessed using percent agreement, absolute agreement, and Cohen's weighted kappa statistic to determine if any of the hypothesized image features correlated with the ability to predict ROP disease trajectory in patients. The central view showed substantial agreement with gestalt scores (κ = 0.63), with moderate agreement in the remaining views. Of retinal components, vascular tortuosity showed the most overall agreement with gestalt (κ = 0.42-0.61), with only slight to fair agreement for all other components. This is a well-defined ROP database graded by one expert in a real-world setting in a masked fashion that correlated with the actual (remote in time) exams and known outcomes. This provides a foundation for subsequent study of telemedicine's ability to longitudinally assess ROP disease trajectory, as well as for potential artificial intelligence approaches to retinal image grading, in order to expand patient access to timely, accurate ROP screening.

Local Anatomic Precursors to New-Onset Geographic Atrophy in Age-Related Macular Degeneration as Defined on OCT.

PURPOSE: In macula-wide analyses, spectral-domain (SD) optical coherence tomography (OCT) features including drusen volume, hyperreflective foci, and OCT-reflective drusen substructures independently predict geographic atrophy (GA) onset secondary to age-related macular degeneration (AMD). We sought to identify SD OCT features in the location of new GA before its onset. DESIGN: Retrospective study. PARTICIPANTS: Age-Related Eye Disease Study 2 Ancillary SD OCT Study participants. METHODS: We analyzed longitudinally captured SD OCT images and color photographs from 488 eyes of 488 participants with intermediate AMD at baseline. Sixty-two eyes with sufficient image quality demonstrated new-onset GA on color photographs during study years 2 through 7. The area of new-onset GA and one size-matched control region in the same eye were segmented separately, and corresponding spatial volumes on registered SD OCT images at the GA incident year and at 2, 3, and 4 years previously were defined. Differences in SD OCT features between paired precursor regions were evaluated through matched-pairs analyses. MAIN OUTCOME MEASURES: Localized SD OCT features 2 years before GA onset. RESULTS: Compared with paired control regions, GA precursor regions at 2, 3, and 4 years before (n = 54, 33, and 25, respectively) showed greater drusen volume (P = 0.01, P = 0.003, and P = 0.003, respectively). At 2 and 3 years before GA onset, they were associated with the presence of hypertransmission (P < 0.001 and P = 0.03, respectively), hyperreflective foci (P < 0.001 and P = 0.045, respectively), OCT-reflective drusen substructures (P = 0.004 and P = 0.03, respectively), and loss or disruption of the photoreceptor zone, ellipsoid zone, and retinal pigment epithelium (RPE, P < 0.001 and P = 0.005-0.045, respectively). At 4 years before GA onset, precursor regions were associated with photoreceptor zone thinning (P = 0.007) and interdigitation zone loss (P = 0.045). CONCLUSIONS: Evolution to GA is heralded by early local photoreceptor changes and drusen accumulation, detectable 4 years before GA onset. These precede other anatomic heralds such as RPE changes and drusen substructure emergence detectable 1 to 2 years before GA. This study thus identified earlier end points for GA as potential therapeutic targets in clinical trials.

Risk of Retinal Artery Occlusion in Patients with Migraine.

PURPOSE: We sought to determine if migraine is associated with increased risk of retinal artery occlusion (RAO). DESIGN: Retrospective cohort study. METHODS: We reviewed a large insurance claims database for patients with migraine and matched control subjects without migraine between 2007 and 2016. Cox proportional hazard regression models were used to investigate the association between migraine and risk of all RAO, central RAO (CRAO), branch RAO (BRAO), and "other" RAO, which includes transient and partial RAO. Primary outcome measures included the incidence of all RAO, including CRAO, BRAO, and other RAO, after first migraine diagnosis. RESULT: There were 418,965 patients with migraine who met the study criteria and were included in the analysis with the appropriate matched control subjects. Among the 418,965 patients with migraine, 1060 (0.25%) were subsequently diagnosed with RAO, whereas only 335 (0.08%) of the patients without migraine were diagnosed with RAO. The hazard ratio (HR) for incident all RAO in patients with migraine compared with those without migraine was 3.48 (95% confidence interval [CI] 3.07-3.94; P < .0001). This association was consistent across all types of RAO, including CRAO (HR 1.62 [95% CI 1.15-2.28]; P = .004), BRAO (HR 2.09 [95% CI 1.60-2.72]; P < .001), and other types of RAO (HR 4.61 [95% CI 3.94-5.38]; P < .001). Patients with migraine with aura had a higher risk for incident RAO compared with those with migraine without aura (HR 1.58 [95% CI 1.40-1.79]; P < .001). This association was consistent for BRAO (HR 1.43 [95% CI 1.04-1.97]; P < .03) and other types of RAO (HR 1.67 [95% CI 1.45-1.91]; P < .001) but was not statistically significant for CRAO (HR 1.18 [95% CI 0.75-1.87]; P = .475). Significant risk factors for this association included increased age, male sex, acute coronary syndrome, valvular disease, carotid disease, hyperlipidemia, hypertension, retinal vasculitis or inflammation, and systemic lupus erythematosus. CONCLUSIONS: Migraine is associated with increased risk of all types of RAO and migraine with aura is associated with increased risk of RAO compared with migraine without aura.

Pentosan Polysulfate Sodium Exposure and Drug-Induced Maculopathy in Commercially Insured Patients in the United States.

PURPOSE: To determine the association and cumulative dose-response pattern between pentosan polysulfate sodium (PPS) use for interstitial cystitis (IC) and maculopathy. DESIGN: Large, multicenter, retrospective cohort study of commercially insured patients in the MarketScan database (Truven Health Analytics, San Jose, CA). PARTICIPANTS: Two hundred twenty-seven thousand three hundred twenty-five patients with IC who were enrolled continuously in the MarketScan database. METHODS: Cox proportional hazards models (controlling for patient gender, age at index diagnosis of IC, and diagnosis with diabetes mellitus) followed up patients from index diagnosis of IC for 5 years, or until patients discontinued insurance coverage, or until patients' first diagnosis with a maculopathy. As a sensitivity analysis, we re-estimate all models after excluding all patients with diabetes. To assess for dose response, we calculated the total days of PPS prescriptions filled and created a categorical variable indicating total exposure. MAIN OUTCOME MEASURES: The primary outcome measure was association between binary PPS exposure and any maculopathy. Secondary outcome measures included exposure between binary and categorical, time-dependent, exposure to PPS and to drusen, nonexudative age-related macular degeneration (AMD), exudative AMD, hereditary maculopathy, and toxic maculopathy. RESULTS: The most common diagnoses of maculopathy in patients with IC were exudative AMD (1.5%), drusen (0.8%), nonexudative AMD (0.3%), toxic maculopathy (0.1%), and hereditary dystrophy (0.04%). In unadjusted analyses, the percentage of patients who filled a PPS prescription and were diagnosed later with a maculopathy (2.37%) was very similar to the percentage of patients who did not fill a prescription (2.77%). Survival models using a binary variable indicating PPS exposure showed no significant associations between PPS exposure and diagnosis of drusen, nonexudative AMD, exudative AMD, toxic maculopathy, hereditary dystrophy, or an aggregate variable of any maculopathy. Similarly, there was no dose-dependent relationship between PPS exposure and diagnosis of any maculopathy. These findings remained stable in sensitivity analysis models that excluded patients with diabetes mellitus. CONCLUSIONS: In this large, commercial claims database analysis, no association was found between PPS exposure and subsequent diagnosis of maculopathy.

Nonmydriatic Photographic Screening for Diabetic Retinopathy in Pregnant Patients with Pre-Existing Diabetes in a Safety Net Population: 1 Year Results from the Diabetic Retinopathy in Pregnant Patients Study.

Background: Pregnant patients with pre-existing diabetes mellitus (DM) are at increased risk for development or progression of existing diabetic retinopathy (DR). A quality improvement project was initiated to improve DR screening during pregnancy at a safety net hospital. This article highlights the utility and generalizability of our telemedicine-based screening model. Materials and Methods: In April 2018, we implemented a photographic retinal screening system in the Maternal Fetal Medicine (MFM) clinic at Santa Clara Valley Medical Center in San Jose, CA. The system is intended to screen all pregnant patients with pre-existing diabetes (type 1 and 2). Retinal images are automatically uploaded to a secure server and interpreted by a retina specialist (C.K.P.). Results: A total of 71 pregnant patients with pre-existing DM were seen in the MFM clinic during the study period. Sixty-six of 71 patients (93.0%) were screened compared with 69.1% in the year prior. Of the 64 patients screened with readable images 11 (17.2%) had DR, whereas 53 did not. Forty-nine of the 64 (74.2%) patients screened underwent screening using the new nonmydriatic system in the MFM clinic. Only 7 out of 47 (14.9%) patients with readable images in the MFM clinic required referral to the ophthalmology clinic. Conclusion: Our model for DR screening in pregnant patients in safety net hospitals is effective in improving screening rates and expediting evaluation and treatment for those in need. This system can prevent irreversible vision loss in pregnant patients and provides an effective framework for ophthalmic care in a safety net hospital system.
