Choroidal thickness in inferior staphyloma associated with posterior serous retinal detachment.

PURPOSE: The purpose of the study was to describe the choroidal findings in eyes with posterior serous retinal detachment associated with inferior staphyloma by enhanced depth imaging optical coherence tomography.

METHODS

The study involved five eyes of five patients with the inferior staphyloma accompanied by posterior serous retinal detachment. In each case, the upper border of the staphyloma was lying across the macula. Enhanced depth imaging spectral domain optical coherence tomography was performed in a vertical-sectional manner through the fovea, and the choroidal thicknesses at the thinnest point, at the fovea, and at 0.5 mm and 1.0 mm superior and inferior to the thinnest point were measured. Fluorescein angiography and indocyanine green angiography were also performed.

RESULTS

In all 5 eyes, the choroid was thinnest at the upper border of the staphyloma (mean, 37.4 μm; SD, 13.5 μm; range, 23-53 μm). Fluorescein angiography showed a band of window defects along the upper border of the staphyloma, where indocyanine green angiography demonstrated persistent hypoperfusion in all 5 eyes.

CONCLUSION

The choroid was markedly thin at the upper border of the inferior staphyloma accompanied by posterior serous retinal detachment. Such choroidal abnormality seemed to play an important role in the development of serous retinal detachment.
