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

description: 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 National
 Eye Institute Visual Functioning Questionnaire-25 (NEI-VFQ-25). Following
 BFT, visual acuity, reading ability, and contrast sensitivity improved
 significantly (p &lt; 0.02), fixation stability and NEI-VFQ-25 scores
 showed a positive trend. These findings indicate that BFT is a feasible
 and promising rehabilitation approach for patients with GA.

 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. ### Files and
