Iridodialysis caused by a blunt force trauma

Iridodialysis, sometimes known as a coredialysis, is a localized separation or tearing away of the iris from its attachment to the ciliary body.Those with small iridodialyses may be asymptomatic and require no treatment, but those with larger dialyses may have corectopia or polycoria and experience monocular diplopia, glare, or photophobia. Iridodialyses often accompany angle recession and may cause glaucoma or hyphema. Hypotony may also occur.Management typically involves observation and bed rest. Red blood cells may decrease the outflow of aqueous humor, therefore the eye pressure should be kept low by giving oral acetazolamide (a diuretic given to reduce intraoccular pressure). Accidental trauma during sleep should be prevented by patching with an eye shield during night time. Avoid giving aspirin, heparin/warfarin and observe daily for resolution or progression. A large hyphema may require careful anterior chamber washout. Rebleeds may require additional intervention and therapy.Later, surgical repair may be considered for larger avulsions causing significant double vision, cosmesis or glare symptoms. Surgical repair is usually done by 10-0 prolene suture taking the base of iris avulsion and suturing it to the scleral spur and ciliary body junction.
