CHANGES IN VISUAL ACUITY AND PHOTORECEPTOR DENSITY USING ADAPTIVE OPTICS AFTER RETINAL DETACHMENT REPAIR

Area of Science:

• Ophthalmology
• Retinal Imaging
• Cell Biology

Background:

• Retinal detachment (RD) can impact photoreceptor integrity and visual function.
• Adaptive optics fundus cameras offer high-resolution imaging of retinal microstructures.

Purpose of the Study:

• To quantify photoreceptor density changes post-retinal detachment (RD) surgery using adaptive optics fundus camera.
• To correlate these changes with macular involvement and best-corrected visual acuity.

Main Methods:

• Adaptive optics imaging was performed at 1 and 3 months post-vitrectomy in 22 patients (10 fovea-OFF, 12 fovea-ON).
• Images were matched between time points using anatomical landmarks.
• Analysis of variance for repeated measures was used.

Main Results:

• Best-corrected visual acuity significantly differed between fovea-OFF and fovea-ON groups at baseline, 1 month, and 3 months post-surgery.
• Cone density decreased in treated eyes compared to fellow eyes.
• Postoperative cone density increased in the fovea-ON group but not in the fovea-OFF group.
• Visual acuity and RD type were independently correlated with cone density.

Conclusions:

• Postoperative cone density reduction was observed in both fovea-OFF and fovea-ON retinal detachment groups.
• The reduction in cone density recovered within 3 months in the fovea-ON group.
• Cone density is significantly correlated with both visual acuity and the type of retinal detachment.
