The purpose of this prospective, longitudinal, single-center observational study is to identify, describe, and measure the morpho-functional characteristics and modifications of the retina and choroid using advanced multimodal imaging techniques. The study will evaluate patients affected by retino-choroidal diseases and compare them with healthy controls over a 5-year follow-up period to track the evolution of these parameters over time.

Change from baseline in retinal thickness measured by OCT
Change in retinal thickness from baseline to each follow-up visit, measured by optical coherence tomography (OCT). Retinal thickness will be reported in micrometers (µm), including central macular thickness and/or retinal layer thicknesses, as applicable.
Time frame: Baseline, 12, 24, 36, 48, and 60 months.
Change from baseline in choroidal thickness measured by OCT
Change in choroidal thickness from baseline to each follow-up visit, measured by OCT and reported in micrometers (µm).
Time frame: Baseline, 12, 24, 36, 48, and 60 months.
Change from baseline in retinal and/or choroidal vascular density measured by OCTA
Change in vascular parameters assessed by OCT angiography, including perfusion density, vessel length density, FAZ area, and/or choriocapillaris flow deficit, reported according to the specific metric generated by the device or analysis software
Time frame: Baseline, 12, 24, 36, 48, and 60 months.
Change from baseline in retinal sensitivity measured by microperimetry
Change in retinal sensitivity assessed by microperimetry and reported in decibels (dB).
Time frame: Baseline, 12, 24, 36, 48, and 60 months.
Change from baseline in cone density measured by adaptive optics
Change in cone density assessed by adaptive optics imaging and reported as cones/mm²
Time frame: Baseline, 12, 24, 36, 48, and 60 months
Change from baseline in qualitative retinal and choroidal imaging features
Qualitative changes in retinal and choroidal morphology, reflectivity, autofluorescence patterns, and ultra-widefield retinal features, assessed by expert ophthalmologists using multimodal imaging.
Time frame: Baseline, 12, 24, 36, 48, and 60 months.
