Lenticonus

Lenticonus is a bulging of the lens capsule and the underlying cortex. The diagnosis of lenticonus is essentially a clinical diagnosis which is made by biomicroscopic examination. According to the localization of the conus a distinction is made between lenticonus anterior and lenticonus posterior. Whereas lenticonus anterior is part of the Alport syndrome, lenticonus posterior is not associated with systemic disease. A case report of each of both types is presented and the clinical presentation, the aetiology, the pathogenesis and the treatment are discussed.
