Microspherophakia Explained

Microspherophakia
Field:ophthalmology

Microspherophakia is a rare congenital autosomal recessive condition where the lens of the eye is smaller than normal and spherically shaped. This condition may be associated with a number of disorders including Peter's anomaly, Marfan syndrome, and Weill–Marchesani syndrome.[1] The spherical shape is caused by an underdeveloped zonule of Zinn, which doesn't exert enough force on the lens to make it form the usual oval shape.[2] It is a result of a homozygous mutation to the LTBP2 gene.[3]
