To assess detached macula in rhegmatogenous retinal detachment by using spectral-domain optical coherence tomography.
This retrospective study included 15 eyes of 15 patients with macula-off rhegmatogenous retinal detachment and 16 eyes of 16 patients with acute central serous chorioretinopathy. These patients were examined with a prototype spectral-domain optical coherence tomography system.
Spectral-domain optical coherence tomography of eyes with rhegmatogenous retinal detachment revealed macular structural abnormalities, such as small cystoid cavities in the inner nuclear layer (2/15 eyes, 13%), cystoid and/or diffuse edema in the outer nuclear layer (10/15 eyes, 67%), undulations of the photoreceptor layer (7/15 eyes, 47%), and dropout of the photoreceptor inner and outer segment layers in the fovea (6/15 eyes, 40%); such changes were not seen in eyes with acute central serous chorioretinopathy. The dropout of foveal photoreceptor inner and outer segment layers was correlated with preoperative and postoperative visual acuities (rs = 0.78, P < 0.005 and rs = 0.63, P < 0.05, respectively), thickness of the outer nuclear layer at the fovea (rs = -0.69, P < 0.01), and height of the retinal detachment at the fovea (rs = 0.60, P < 0.05).
Dropout of the foveal photoreceptor inner and outer segment layers seen on spectral-domain optical coherence tomography imaging may be involved in incomplete recovery of visual acuity after successful retinal reattachment surgery.
