Abstract Details


To investigate the choroid macrostructure in rhegmatogenous retinal detachment


Retrospective imaging study


We evaluated the subfoveal choroidal thickness (SFCT) in spectral domain optical coherence tomography image. All images were high definition and obtained from single machine using enhanced depth mode. Choroid thickness was measured from two independent grader and image was excluded if one of them was not able to determine the thickness. Duration of symptom, location of retinal detachment and foveal involvement were analysed.


Total 68 patients were included. Thirty four patients were female. Foveal detachment was observed in 34 patients. SFCT was thicker in detached eye than healthy eye (242.1 ± 73.9 µm in diseased eye vs 216.5 ± 81.8 µm in healthy eye, P < 0.001). Choroidal thickness difference between diseased and healthy eye was larger in foveal detachment cases. (35.8 ± 56.4 µm vs 5.5 ± 31.8 µm, P = 0.20) Duration of symptom or location of primary detachment (superior vs. inferior) did not make significant difference.


Subfoveal choroidal thickness was thicker in rhegmatogenous retinal detachment than healthy contralateral eye, and the difference was larger in foveal detachment cases.
