Abstract Details

Purpose:

To evaluate and compare flow and vascular density in the retina and choroid in eyes with pseudoexfoliation (PEX), non-PEX fellow eyes, and healthy eyes using optical coherence tomography angiography (OCTA).

Setting:

Ophthalmology Department, Military hospital of Tunis, Tunisia

Methods:

A prospective, case–control study of 21 patients with unilateral PEX syndrome were imaged using OCTA and compared to non-PEX fellow eyes, and healthy eyes. Flow area and vessel density (VD) in the superficial capillary plexus (SCP) and deep vascular plexus (DCP) were measured by OCTA as three separate parameters: total, parafoveal, and foveal. Choroidal thickness (CT) and foveal avascular zone (FAZ) area were measured for each patient.

Results:

A prospective, case–control study of 21 patients with unilateral PEX syndrome were imaged using OCTA and compared to non-PEX fellow eyes, and healthy eyes. Flow area and vessel density (VD) in the superficial capillary plexus (SCP) and deep vascular plexus (DCP) were measured by OCTA as three separate parameters: total, parafoveal, and foveal. Choroidal thickness (CT) and foveal avascular zone (FAZ) area were measured for each patient.

Conclusions:

In our series, PEX eyes have significant damage to the retinal and choroidal vascular structures associated with PEX material. Further research is needed to understand better the pathophysiological significance of the retinal   and choroidal alterations present in PEX eyes
