Serous retinal detachment as a sign of leukemic choroidopathy: A systematic review

Abstract

Leukemia is a rare disease associated with a high mortality rate. The presence of unilateral or bilateral serous retinal detachment (SRD) as a sign of choroidal infiltration can be one of the manifestations of acute leukemia, both as a primary sign or in a relapse. We consolidated the literature on SRD as a sign of leukemic choroidopathy regarding its epidemiology, clinical manifestations, and main imaging diagnostic tools. Well-documented cases regarding acute lymphoblastic leukemia (ALL), acute myelogenous leukemia (AML), relapsed ALL and relapsed AML published until September, 2020, in peer reviewed journals were included. The literature shows an interesting range of choroidal infiltration cases assessed by modern imaging techniques, such as optical coherence tomography (OCT) with and without enhanced depth imaging (EDI) and fluorescein angiography (FA). These tools allow choroidal assessment and better understanding and characterization of this rare condition. Complete ophthalmological workup should be performed in these patients using both FA and EDI-OCT to assess the choroidal anatomy and integrity. An increase in choroidal thickness measured with EDI-OCT can reveal active disease and potentially diagnose a leukemic relapse promptly.
