Biofeedback fixation training in the rehabilitation of patients suffering from geographic atrophy

Geographic atrophy (GA) is a progressive cause of central vision loss with limited rehabilitation options. This prospective case series aimed to evaluate the effects of biofeedback fixation training (BFT) on visual function and vision-related quality of life (QoL) in patients with GA. Eighteen patients with total central vision loss in one eye underwent BFT on the fellow eye (study eye) using the Macular Integrity Assessment (MAIA) system, which was used to select a new, previously chosenpreferred fixation locus (PRL) to stabilize fixation or adopt a new fixation locus. Patients were followed for an average of 13.2 months (3-26 months). Functional outcomes included best corrected visual acuity (ETDRS chart), reading performance (Radner test), and contrast sensitivity (Spot Checks test). MAIA parameters comprised average retinal sensitivity, fixation distance, and stability (P1, P2), and changes in the bivariate contour ellipse area (BCEA). Vision-related QoL was assessed using the Natio..., , # Data from: Biofeedback fixation training in the rehabilitation of patients suffering from geographic atrophy

## Description of the data and file structure

The patients of our prospective case-series study were examined and followed in the Department of Ophthalmology, Semmelweis University, Budapest, Hungary, between 2023 and 2025. The study was approved by the Institutional Ethics Review Board at Semmelweis University (SE RKEB RKEB: 136/2023, SE TUKEB 248/2016, 037871/2016/OTIG, OGYÉI/42821/2019, OGYÉI/12949/2023) and carried out in accordance with the Principles of the Helsinki Declaration. Signed informed consent was obtained from each subject after explanation of the nature and possible consequences of the study.

Patient selection was carried out from among patients with GA who attended our clinic's general outpatient clinic and retina outpatient clinic.
