Choroidal Thickness in Clinically Significant Pseudophakic Cystoid Macular Edema

Dominik Odrobina et al. Retina.

Abstract

Purpose: To study the choroidal thickness with an enhanced depth imaging spectral domain optical coherence tomography in clinically significant pseudophakic cystoid macular edema (CME).

Methods: Twenty patients with CME after uneventful cataract surgery were included. Choroidal thickness was analyzed and measured at various points: subfoveal and 1.5 mm nasal, 1.5 mm temporal, 1.5 mm inferior, and 1.5 mm superior from the center of the fovea. We compare choroidal thickness between affected and fellow eyes.

Results: The mean subfoveal choroidal thickness measured in 28 eyes with CME was 229.14 ± 62.61 μm and 280.82 ± 79.09 μm in fellow eyes. At any point (subfoveal, 1,500 μm; nasal, 1,500 μm; temporal, 1,500 μm; inferior, 1,500 μm; 1,500 μm superior from the center of the fovea), the choroidal thickness of the affected eye was significantly (P < 0.01) thinner than that of the fellow eye.

Conclusion: The thinner choroid in eyes with CME than in fellow eyes may suggest that the reduced choroidal blood flow in the choriocapillaris is also a possible factor of CME.
