[Acute retinal pigment epitheliitis. Diagnosis using optical coherence tomography].

CASE REPORT: A 17 year-old female presented with a bilateral and acute visual loss. On ophthalmoscopic examination, there was a subfoveal deposit with a vitelliform appearance. Optical coherence tomography revealed a hyperreflective and homogeneous material located at the photoreceptor external segment layer. A month later, vision had spontaneously recovered and macular appearance was normalised. On tomography, the subretinal material had completely disappeared.

DISCUSSION: Acute retinal pigment epitheliitis is a rare condition that usually causes a transient visual loss, with a good prognosis in young subjects.
