Purpose

To evaluate the changes in thickness of central retina, thickness of choroidal layers before and after cataract surgery and determine the impact of vitreoretinal surface status on these parameters

Setting/Venue

Alanya Alaaddin Keykubat University Faculty of Medicine, Department of Ophthalmology, Antalya, Turkey

Methods

Retrospective study included 64 patients (64 eyes) with no macular disorder who underwent phacoemulsification, and had stored spectral domain optical coherence tomography (OCT) imagings within 1 week preoperatively as well as at 1 and 3 months postoperatively. The evaluated SD-OCT parameters were central foveal thickness (CFT), subfoveal choroidal thickness (SFCT), the large choroidal vessel layer thickness (LCVL) and the Sattler’s layer/ choriocapillaris thickness (SCVL), vitreoretinal status including “vitreomacular adhesion” (VMA), “no vitreoretinal contact visible”, and pseudophakic cystoid macular edema (PCME).

Results

Seventeen eyes (26.6%) had VMA. The preoperative SD-OCT parameters of the two groups were not statistically significant (p>0.05). The mean CFT values at post operative first month were statistically significantly higher in VMA group (p=0.01). Pseudophakic cystoid macular edema was observed in the postoperative first month in two eyes (3.1%) which also had VMA. No statistically significant difference was found between preoperative and postoperative SFCT values (p=0.1, 0.2, 0.5, respectively).

Conlusions

Pre-surgical vitreomacular adhesion may be a risk factor for development of PCME after uncomplicated cataract surgery. Choroidal expansion response after cataract surgery was not associated with pseudophakic cystoid edema.
