Use of multimodal analysis in the diagnosis and follow-up of a case of Acute Zonal Occult Outer Retinopathy (AZOOR)

Abstract

A clinical case is presented in order to show the usefulness of multimodal analysis in the diagnosis and monitoring of patients with Acute Zonal Occult Outer Retinopathy (AZOOR). A 22 year-old patient was seen in the emergency department complaining of photopsia and paracentral scotoma of the left eye. Several structural and functional tests were performed and the patient was diagnosed with AZOOR. The evolution of the case was towards an initial structural worsening, followed by the almost complete resolution of the lesions identified in the different tests carried out, with an obvious symptomatic improvement. Multimodal analysis of AZOOR cases allows a fairly accurate diagnosis of this condition, and its differentiation from others with a similar appearance, such as multiple white point syndromes, or multifocal choroiditis.
