Lens subluxation with vitreous (Video)

This video shows a cataract lens that has dislocated backwards after blunt trauma. You can even see a veil of vitreous coming around the lens into the anterior chamber. This cataract will be difficult to remove, as an anterior approach is unsafe (there is too much zonular dehiscence such that the lens might fall into the back of the vitreous). Instead, it was removed by a two-step approach: a posterior lens removal by a retinal surgeon with a later anterior chamber lens placement by a cataract surgeon.

While this lens misplacement occured from trauma, other causes of lens displacement include heriditary conditions (Marfan’s syndrome, homocystinuria, hyperlysinuria sulfite oxidase deficiency, Weill-Marchesani syndrome, aniridia and Ehlers-Danlos syndrome) and from hypermature cataracts where the lens has gotten so big that the zonular support springs are lost.

Subluxed Lens
This photograph shows a subluxed lens that has turned white, that occured after blunt trauma to the eye. The lens has shifted to the left and the vitreous jelly has squeezed into the anterior chamber
Vitreous in the AC
This photograph shows a veil of vitreous that is presenting around a subluxed lens. The initial injury was extreme blunt trauma to the eye, which ripped the lens zonules and turned the lens cataractous.
Traumatic cataract
This photograph shows a veil of vitreous that is presenting around a subluxed lens. The initial injury was extreme blunt trauma to the eye, which ripped the lens zonules and turned the lens cataractous.
