Delbosc, Maher Saleh. Ophthalmology, UniversityHospital of Besançon, Besançon, France.Purpose: To determine age-related macular photoreceptor densitychanges in healthy patients of various ages.Methods: Observational case series. Healthy subjects with no retinalpathology or systemic affection were included. High myopic patientswere excluded. All patients underwent a full ophthalmologicexamination, SD-OCT imaging, and imaging with the RTX-1 Adaptive Optics (AO) retinal camera from Imagine eyes® (Orsay,France).Mean cone density (cells/mm2) at a fixed distance from the fovea (1°nasally and temporally), spacing between cells (µm) and % ofhexagonal cells calculated on Voronoi diagrams, were obtained usingAODetect v. 0.1, the proprietary software of the device.Results: 58 normal eyes of 35 patients were studied. Mean age was34.45±2.5 y (min-max: 10-78y). The mean cone density reached24039±2914.5 cells/mm2. It decreased with age (R2=0.21, p
