Macular edema in Cogan-Reese syndrome

PURPOSE

Iridocorneo-endothelial (ICE) syndrome is known as a rare spectrum causing glaucoma, corneal and iris damages. Retinal complications are uncommon.

OBSERVATIONS

We report the case of a middle-aged woman suffering from a Cogan-Reese Syndrome (CRS) with refractory ocular hypertension (OHT) who presented a cystoid macular edema (CME) during follow up.

CONCLUSIONS AND IMPORTANCE

We suspect the CME to be inflammatory linked to the pathophysiological hypotheses of the CRS. The CME was successfully treated with topical nonsteroidal anti-inflammatory drugs (NSAID). No consensus is available on its duration. A recurrence happened when treatment was stopped, its reintroduction was successful.

Diseases of the corneal endothelium

The corneal endothelial monolayer and associated Descemet's membrane (DM) complex is a unique structure that plays an essential role in corneal function. Endothelial cells are neural crest derived cells that rest on a special extracellular matrix and play a major role in maintaining stromal hydration within a narrow physiologic range necessary for clear vision. A number of diseases affect the endothelial cells and DM complex and can impair corneal function and vision. This review addresses different human corneal endothelial diseases characterized by loss of endothelial function including: Fuchs endothelial corneal dystrophy (FECD), posterior polymorphous corneal dystrophy (PPCD), congenital hereditary endothelial dystrophy (CHED), bullous keratopathy, iridocorneal endothelial (ICE) syndrome, post-traumatic fibrous downgrowth, glaucoma and diabetes mellitus.
