Normal foveal threshold
Web19 de nov. de 2024 · Introduction. Various ocular diseases and high myopia influence the anatomical reference point Foveal Avascular Zone (FAZ) dimensions. Therefore, it is important to segment and quantify the FAZs dimensions accurately. To the best of our knowledge, there is no automated tool or algorithms available to segment the FAZ’s … Web16 de abr. de 2024 · Data for lesion size, CRT, MD of perimetric sensitivity, and foveal threshold at baseline and after 6 and 12 months of IVA are shown in Figure 2B – E. Lesion size, CRT, and MD of perimetric sensitivity improved significantly after 12 months compared with baseline ( P =0.0090, P <0.0001, and P =0.0021).

WebFoveal detection thresholds of the RP subjects showed the greatest elevation at low background luminances and approached normal values at high adapting levels. There was a statistically significant correlation (r = 0.79, P less than 0.01) between the visual acuities and absolute thresholds of the RP subjects. WebPurpose: To determine whether baseline foveal threshold and photoreceptor integrity can predict best-corrected visual acuity (BCVA) at 12 months after intravitreal aflibercept (IVA) therapy in eyes with neovascular age-related macular degeneration (AMD). Patients and methods: We evaluated 25 eyes of 25 patients with treatment-naïve neovascular ...
