Purpose To present a case of nonexudative choroidal neovascularization secondary to angioid streaks in a patient with pseudoxanthoma elasticum. The lesion was monitored over an 8-month period with the use of optical coherence tomography angiography. Methods Case report. Results The neovascular tissue area increased by 0.160 mm2 over a period of 8 months without any sign of exudation seen on optical coherence tomography or fluorescein angiography. Conclusions To our knowledge, this is the first report of a nonexudative choroidal neovascularization secondary to angioid streaks. Given that once a patient with angioid streaks develops choroidal neovascularization in one eye there is a high risk of bilateral involvement within a short amount of time, optical coherence tomography angiography can prove a useful tool for monitoring such lesions over time.

Objective: To evaluate the diagnostic value of optical coherence tomography angiography (OCTA) in detecting the choroidal neovascularization (CNV) in agerelated macular degeneration (AMD). Methods: A systematic review and meta-analysis was performed by searching Pubmed, Science Direct, Embase and Web of Science. The pooled sensitivity and specificity with 95% confidence intervals (CIs), area under the summary receiver operator characteristic curve (sROC), and the total accurate classification rate were used to evaluate OCTA’ diagnostic value of CNV in AMD patients. Results: Seven studies involving 517 eyes were included in the analysis. The mean age of subjects in each study ranged from 58.5 years to 81.7 years. Fluorescein angiography was applied as the gold standard in five studies. There were 350 eyes diagnosed with CNV, OCTA detected 301 eyes correctly, while among the 167 eyes without CNV, OCTA identified 150 correctly. The total accurate classification rate was 87.23%. The Spearman's rank correlation coefficient was 0.5, indicating that there was no significant threshold effect in the current study (S=8, p=0.103). The pooled sensitivity and pooled specificity were 0.89 (95%CI: 0.82,0.94) and 0.96 (95%CI: 0.85,1.00) respectively. The area under sROC was up to 0.911. Conclusion: The specificity of OCTA for the detection of CNV in AMD patients is extremely high, however, the sensitivity still needs to be improved. In general, the metaanalysis revealed that OCTA had a high diagnostic value for the detection of CNV in AMD patients.

Purpose: To detect the vessel density (VD) of the radial peripapillary capillary (RPC) in eyes affected by pathological myopia with or without a peripapillary intrachoroidal cavitation (PICC) and in eyes with PICC complicated by choroidal neovascularization (CNV), using optical coherence tomography angiography (OCTA). Methods: We prospectively enrolled highly myopic patients from January 2016 to December 2019 at the Eye Clinic of the University of Naples “Federico II.” We divided included patients into three groups: group 1 including patients with PICC complicated by CNV; group 2 including patients with PICC without complications; group 3 including patients with high myopia without PICC and CNV. One-way analysis of variance (ANOVA) followed by Bonferroni post hoc analysis was used to evaluate differences in VD of radial peripapillary capillary (RPC) in papillary whole, peripapillary regions and its sectors among the three groups. Results: We enrolled 12 highly myopic eyes with PICC complicated by CNV, 21 highly myopic eyes with PICC without CNV and 23 highly myopic eyes without PICC. The myopic eyes with PICC revealed a statistically significant reduction in VD of the RPC comparing to the other groups ( p < 0.001), especially in eyes affected by myopic PICC complicated by CNV ( p < 0.001). These results were similar analyzing the VD in different sectors of the peripapillary region among the three groups ( p < 0.001). Conclusion: OCTA detects the changes in peripapillary vascular density of highly myopic eyes. We demonstrated that the RPC vasculature is significantly influenced by the presence of PICC, especially in myopic eyes developing a CNV.
