Dislocation of lens
Answer: A. Dislocation of lens
Explanation: Blunt trauma may cause sudden compressive deformation of the globe causing transient shortening of the eye in the antero-posterior direction displacing the cornea and anterior sclera posteriorly. This causes a compensatory expansion of the globe in the equatorial plane, which can stretch or break the zonules.1 Traumatic zonular dialysis is a major cause of lens subluxation and dislocation in which partial zonular dialysis may lead to subluxation and complete zonular rupture leads to dislocation.
Beside trauma, lens dislocation is seen in hereditary disorder like congenital aniridia, congenital glaucoma, cystathionine b-synthase deficiency, Ehlers-Danlos syndrome, focal dermal hypoplasia, homocystinuria, Kniest dysplasia, Marfan’s syndrome, molybdenum cofactor deficiency, sulfite oxidase deficiency, Weill-Marchesani syndrome.
