A unique case of microspherophakia in adult Refsum disease

Year: 2025

Type: article

Abstract: Adult Refsum disease (RD) is a rare autosomal recessive peroxisomal disorder with an estimated prevalence of fewer than 1 in 1 million. The ocular manifestations result from the accumulation of phytanic acid, leading to retinitis pigmentosa, attenuated retinal vessels, bone spicule pigmentation, optic disc pallor, and macular involvement in advanced stages. To date, there has been no documented association between RD and microspherophakia, a rare lens abnormality more commonly linked to Weill-Marchesani syndrome. Microspherophakia is characterized by a small lens diameter, increased anteroposterior thickness, and a visible lens equator upon full mydriasis. We present a unique case of concurrent RD and microspherophakia.
