Abstract
To assess the effectiveness of anti-VEGF therapy in different types of fluids localization in neovascular age-related macular degeneration (AMD). The study included 16 people (16 eyes) with exudative AMD. The study included patients with fibrovascular detachment of the retinal pigment epithelium (RPE), subretinal and intraretinal fluid. The patients were divided into two groups: in the first group, fibrovascular RPE detachment was combined with subretinal fluid (9 eyes); in the second group, fibrovascular RPE detachment was accompanied by both sub- and intraretinal fluid (7 eyes). All patients underwent standard ophthalmological examination, which included visometry, biomicroscopy, and ophthalmoscopy under conditions of drug-induced mydriasis. Additionally, OCT of the macular region and OCT-angiography were performed. Over the entire observation period, the first group of patients received an average of 5.11 intravitreal injections (IVI), the second group - 5.14 IVI. Visual acuity was comparable in both groups at the beginning of the study. Subsequently, the treatment resulted in an increase in visual acuity after 3 months in the first (p=0.066) and second (p=0.043) groups, as well as after 12 months in both groups (p=0.043). In the first group of patients, after 12 months, an increase in RPE detachment was observed (p=0.942), which suggests that the disease activity remains underestimated on OCT when RPE detachment and subretinal fluid are combined. In the first group, complete resorption of subretinal fluid occurred in 2 people. In the second group, resorption of subretinal and intraretinal fluid occurred in 6 people. Regardless of the subtype of fluid, anti-VEGF therapy is an effective method for treating exudative AMD. Intravitreal injections are necessary both in the presence of intra- and/or subretinal fluid, and fluid under RPE. The greatest difficulty is assessment of the fluid under the RPE.
