Acute transient choroidal elevation induced by hyperpermeability of asymmetrical pachyvessel over-crossed watershed zone

Abstract

Purpose

To describe a case of an elderly woman who presented with acute choroidal elevation, and the elevation disappeared without any treatment a month after the onset.

Observation

A 64-year-old woman presented to the clinic with complaint of blurred vision in her left eye. Her left visual acuity was 20/32 and choroidal elevation in the macular and subretinal fluid of the left eye was observed with optical coherence tomography (OCT), and no abnormalities in her right eye. Her fundus examination and OCT revealed a choroidal elevation and sub-retinal fluid (SRF) around the inferior temporal area, including the fovea in her left eye. No abnormalities on OCT were found after three months without any treatments, and the patient's BCVA improved to 20/20 with blurred vision.

Conclusions and importance

Choroidal elevation is often suspected as an intraocular tumor. This case showed a transient choroidal elevation that improved without treatment. The characteristic finding of this case was an abnormal, hyperpermeable choroidal pachyvessel crossing the watershed zone.
