Post-cataract surgery cystoid macular edema from choriocapillaris submacular leakage in a patient with crohn disease: a case report.
OBJECTIVE
To describe an unusual case of cystoid macular edema after cataract surgery in a patient with Crohn disease.


METHODS
A confocal scanning laser ophthalmoscopic study was performed on one eye before and after systemic corticosteroid treatment. Both fluorescein and indocyanine green angiograms were used to visualize vascular leakage.


RESULTS
Both fluorescein and indocyanine green angiograms indicated early-phase leakage in the macular region. The early-phase indocyanine green leakage was from choroidal vasculature and suggested choriocapillaris vasculitis. In the later phases, the fluorescein angiogram showed the typical petaloid pattern of cystoid macular edema. After 1 month of treatment, the abnormal indocyanine green leakage disappeared with a concomitant increase in visual acuity.


CONCLUSIONS
We report possible choriocapillaritis associated with Crohn disease based on dynamic angiography that revealed indocyanine green leakage in combination with early-phase fluorescein leakage. To our knowledge, this is the first description of choriocapillaris vasculitis associated with Crohn disease.
