-Spherophakia is a rare congenital bilateral eye disorder.
-Usually patients present in adolescence or young adulthood.
-Presents with weak zonules around a more spherical crystalline lens with an increased anteroposterior thickness of the lens, and highly myopic eye.
-The lens zonules are developmentally hypoplastic and abnormally weak and due to non-attachment of the posterior zonules to the equatorial zone of the lens, the lens changes its normal shape to spherical.
-The lens may undergo subluxation or dislocation from the patellar fossa, leading to defective accommodation.
-The disease can present as an isolated condition or may run in families (due to consanguinity).
-Subluxation of lens may occur anteriorly, inferiorly, or posteriorly and may lead to pupillary block glaucoma.
FEATURES:
-Spherical lens.
-Iridodonesis.
-Axial myopia.
-Glaucoma.
MANAGEMENT:
-Lensectomy for managing the dislocated lens.
-Visual rehabilitation becomes important, with options being aphakic spectacles, contact lenses, and IOLs.
