Diagnostic evaluation of optical coherence tomography angiography and fundus autofluorescence in bilateral diffuse uveal melanocytic proliferation.

ABSTRACT: Purpose:To demonstrate the utility of optical coherence tomography angiography (OCTA) in visualizing the choroidal vasculature in bilateral diffuse uveal melanocytic proliferation (BDUMP), so as to elucidate pathophysiology and also aid in diagnosis. Additionally, to recommend autofluorescence (AF) over traditional angiography for purposes of noninvasive diagnosis. Observations:Three BDUMP cases are examined using AF, and two are examined using OCTA. Additionally, the cases vary in etiology and include a case with iris cysts, which we believe to have only been recorded once before in scientific literature, steroids were successfully used to treat two cases and anti-tumor drugs were used to treat the third case. OCTA revealed altered choroidal vasculature in the two cases tested, and AF was successfully used to diagnose all three cases regardless of etiology. Conclusions and importance:We believe the OCTA findings are potentially elucidative regarding the pathophysiology at the choroidal layer, where BDUMP lesions primarily exist. Given the limited number of recorded BDUMP cases and relatively unknown pathophysiology, OCTA may prove to be invaluable in visualizing disease progression. Also we were able to use AF to diagnose all three cases ranging from extremely rare iris cysts to a more conventional presentation, indicating its utility regardless of etiology.

Project description:PurposeTo evaluate the peripapillary and perifoveal retinal perfusions of young healthy eyes with a tessellated fundus using optical coherence tomography (OCT) angiography.MethodsThirty-five Chinese subjects with a tessellated fundus and 35 subjects without a tessellated fundus from a population-based cross-sectional study in Shanghai were included. All participants underwent OCT angiography. The flow index and vessel density were examined in the peripapillary and perifoveal retinal areas, and their relationships with other ocular parameters were analyzed.ResultsIn the peripapillary area, the eyes with a tessellated fundus had a lower retinal nerve fiber layer (RNFL) flow index (0.055 ± 0.009 vs. 0.061 ± 0.007, P = 0.006), RNFL vessel density (61.8 ± 7.3 vs. 65.9 ± 5.2, P = 0.010), retinal flow index (0.086 ± 0.010 vs. 0.092 ± 0.008, P = 0.012), and retinal vessel density (83.7 ± 5.0 vs. 86.4 ± 3.7, P = 0.018) than the control eyes, and the difference remained significant even after adjustments were made for gender and RNFL thickness. No difference was found in the perifoveal area. Multivariable linear regression analysis showed that the retinal flow index and vessel density in the peripapillary area were significantly correlated with the tessellated fundus diagnosis (flow index: β = -0.006, P = 0.005; vessel density: β = -2.597, P = 0.006), gender (flow index: β = 0.005, P = 0.019; vessel density: β = 3.129, P = 0.002) and RNFL thickness (flow index: β = 0.000, P = 0.002; vessel density: β = 0.190, P = 0.002). The RNFL flow index and vessel density were significantly associated with the tessellated fundus diagnosis (flow index: β = -0.005, P = 0.005; vessel density: β = -3.572, P = 0.008) and the thickness of RNFL (flow index: β = 0.001, P < 0.001; vessel density: β = 0.421, P < 0.001).ConclusionsEyes with tessellated fundus with a relative decreased peripapillary retinal perfusion compared with eyes without a tessellated fundus were observed. The findings whether indicate causality that the reduction in the peripapillary perfusion and the peripapillary atrophy in myopia, need further study.

Project description:ImportanceCoats disease is a rare pediatric vitreoretinopathy that can cause devastating visual and anatomic outcomes.ObjectiveTo compare optical coherence tomography (OCT) with fundus photographs, fluorescein angiography (FA), and histopathologic findings in Coats disease.Design, setting, and participantsThis retrospective cohort study was conducted in a single tertiary institution (Duke Eye Center) and identified 28 children with Coats disease through a review of medical records from December 2002 to January 2018. Four eyes were obtained from a biorepository for histopathologic analysis.Main outcomes and measuresMacular OCT, fundus photographs, and FA results were reviewed and compared for morphological changes. These were compared with retinal histopathological findings.ResultsThe mean (SD) age was 9.5 (5.5) years for the 28 children (and 29 eyes) with clinical imaging results, and 24 (86%) were boys. A comparison between imaging modalities revealed OCT features that were not visible in photographs or FA, including exudates in multiple retinal layers (23 [82.1%]), small pockets of subretinal fluid (4 [14.3%]), an outer retinal atrophy overlying fibrotic nodules (7 [25.0%]), and small preretinal hyperreflective OCT dots (25 [89.3%]). Next, a comparison with light micrographs introduced an association of OCT findings with possible pathological features, including hyperreflective linear structures on OCT that appeared consistent with cholesterol crystals, small hyperreflective dots with macrophages, outer retinal tubulations with rosettes, and analogous OCT histopathology features such as intraretinal vessels entering fibrotic nodules and retinal pigment epithelium excrescences under the subretinal fluid. An OCT analysis revealed intraretinal cystoid spaces in 19 eyes, but in 9 of 19 (47.4) this was not associated with cystoid macular leakage; rather, fluorescein leakage was observed from peripheral telangiectatic vessels. Additionally, exudates were intraretinal only (6 [21.4%]) or both intraretinal and subretinal (17 [60.7%]); none were subretinal only. In eyes with follow-up results, new fibrosis developed in 8 of 17 eyes (47.1%). Fibrosis developed in 5 of 5 eyes (100%) with baseline subretinal fluid vs 3 of 12 without (25%; 95% CI, 22%-92%) and in 7 of 9 eyes (77.8%) with subretinal exudates vs 1 of 8 (12.5%) without (95% CI, 16%-89%).Conclusions and relevanceOptical coherence tomography may show the transient and permanent effects of Coats disease on the retina. These results suggest that exudates and fluid in the macular subretinal space appear later in the disease and may result in fibrosis formation. Further studies are needed to confirm if early treatment could prevent vision-threatening macular fibrosis.
