Microperimetry, Spectral-Domain OCT and Fundus Flourescein Angiography in the follow up of a case of Acute Retinal Pigment Epithelitis (ARPE)

Acute retinal pigment epithelitis (ARPE), also known as Krill's disease, was first described by Krill and Deutman in 1972 as a bilateral, benign, self limited disease [1]. There are many recent reports [2-5]. That describes the Spectral Domain Optical Coherence Tomography (SD-OCT) findings in ARPE. Lesions of the RPE, inner and outer segments of photoreceptors and external limiting membrane and sub-retinal deposits have all been implicated in the pathology of ARPE. Poor visual acuity at baseline and involvement of the ELM or ONL on SD-OCT at baseline were associated with the incomplete recovery of visual acuity [2]. In a report of 3 cases, in the acute stage, SD-OCT demonstrated abnormal hyper reflectivity involving the photoreceptor outer segment layer and hypo reflectivity involving the associated RPE layer in all cases. In the chronic stage, SD-OCT showed decreased abnormal reflectivity. Resolution of hyper-reflective and disrupted
