Spectral domain optical coherence tomography and autofluorescence in a case of acute posterior multifocal placoid pigment epitheliopathy mimicking Vogt-Koyanagi-Harada disease: case report and review of literature.

PURPOSE

To report a case of acute posterior multifocal placoid pigment epitheliopathy (APMPPE) with exudative retinal detachment, simulating acute Vogt-Koyanagi-Harada (VKH) disease and to review relevant imaging literature.

METHODS

Ophthalmologic examination, laboratory evaluation, fluorescein angiography, and B-scan ultrasonography performed at baseline, as well as spectral domain optical coherence tomography (OCT) and fundus autofluorescence performed upon initial presentation and at 5-day, 1-month, and 3-month follow-up.

RESULTS

OCT demonstrated outer retinal hyperreflectance and subretinal fluid in the acute phase that disappeared 5 days later. Choroidal thickening was noted on OCT and ultrasonography. Retinal pigment epithelium lesions were hypoautofluorescent acutely but became hyperautofluorescent later in the disease course.

CONCLUSIONS

At presentation, there can be considerable overlap in both clinical and imaging findings in APMPPE mimicking acute VKH, making it difficult to differentiate these two entities. Cerebral spinal fluid analysis and follow-up examinations could help in arriving at proper diagnosis.
