Aim:
To assess the morphological characteristics of uveitic macular edema studied with Spectralis optical coherence tomography (OCT) and to investigate the correlation between the tomographic features and visual acuity.
Methods:
71 eyes of 55 patients underwent examination with Spectralis OCT (Heidelberg Engineering, Germany). Data was correlated with logMAR best-corrected visual acuity (BCVA).
Results:
Two morphological patterns were observed: cystoid macular edema (CME) in 69% and diffuse macular edema in 31% of eyes. BCVA was 0.2 in CME, 0.1 in diffuse edema (p = 0.008). Foveal thickness was 413.4 ± 212 µm in CME, 311.27 ± 53 µm in diffuse edema (p = 0.03). BVCA was 0.3 in eyes with serous retinal detachment (SRD), 0.2 in eyes without SRD (p = 0.02). BCVA was 0.4 in eyes with inner segment/outer segment (IS/OS) disruption, 0.1 in eyes with integrity of the IS/OS junction (p = 0.01).
Conclusions:
BCVA is negatively correlated with cystoid pattern, foveal thickening and SRD. Disruption of the IS/OS junction is associated with poor vision in uveitic macular edema.
