Microperimetry of Subretinal Drusenoid Deposits.
No full textTo investigate light sensitivity in eyes presenting with subretinal drusenoid deposits (SDD). Methods: All consecutive patients with SDD only seen between January 2012 and July 2012 were included. A control group of consecutive age- and sex-matched control subjects presenting at least one eye with early age-related macular degeneration was considered. In all cases best-corrected visual acuity (BCVA), color fundus photography, fundus autofluorescence imaging and spectral-domain-optical coherence tomography with integrated microperimetry were performed. Results: Twenty-one eyes (21 patients, 9 females, 12 males, mean age 69.2 ± 5.3 years, mean BCVA 0.18 ± 0.14 LogMAR) were included in the SDD group. Twenty eyes of 20 patients (13 females, 7 males, mean age 69.1 ± 3.9 years, mean BCVA 0.16 ± 0.15 LogMAR) were included in the control group. In eyes with SDD the choroid was thinner at the subfoveal location, and at 1,500 μm superior, inferior, temporal and nasal to the fovea (p < 0.05). In eyes with SDD, the overall mean light sensitivity in the central macula (4.21 ± 2.46 dB) was significantly reduced when compared to the control group (6.81 ± 2.12 dB, p = 0.001), while stable fixation was present in both groups. Correlation between BCVA and mean light sensitivity in the central 7 × 7 mm square was low in the SDD group (Pearson's rho = 0.4, p = 0.01), while it was good in the control group (Pearson's rho = 0.7, p = 0.001). Conclusions: Eyes with SDD showed reduced sensitivity despite preserved BCVA. Reduced choroidal thickness could be involved in reduction of light sensitivit

Full text linkPurpose: 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
