MULTICOLOR IMAGING IN A CASE OF ACUTE RETINAL PIGMENT EPITHELIITIS

To describe multicolor imaging findings in a case of acute retinal pigment epitheliitis.

Vitreoretinal department of a tertiary care center in Eastern India.

A 28-year-old lady presented with acute vision loss in the right eye since 3 days. Left eye examination was unremarkable. Best-corrected visual acuity in the right eye was 20/40. Anterior segment examination revealed clear lens with no evidence of inflammation. There were no vitreous cells. Fundus examination of the right eye revealed a round orange lesion surrounded by a hypopigmented halo in the fovea with multiple tiny hypopigmented lesions temporal to the fovea. Fundus autofluorescence imaging of the right eye showed hyperautofluorescent lesions temporal to the fovea corresponding to the hypopigmented lesions seen temporal to the fovea. Spectral domain optical coherence tomography of the right eye revealed subfoveal hyperreflective lesion in the outer retina with disruption of the ellipsoid zone and interdigitation zone with a linear extension upward. Multicolor composite image of the right eye revealed the foveal lesion as circular red patch with an inferior orange extension. The infrared reflectance image revealed hyperreflective area corresponding to the foveal lesion. The blue and green reflectance images were unremarkable. The patient reported an upper respiratory tract infection 7 days before the visual loss. A diagnosis of acute retinal pigment epitheliitis was made based on history, clinical and imaging findings.

This is the first description of multicolor imaging signature of acute retinal pigment epitheliitis lesion in published literature. It seems to be a promising noninvasive imaging modality with a potential to replace color fundus photography.
