Isoexpansile sulfur hexafluoride gas to repair near-total iris disinsertion

摘要

Iridodialysis is commonly encountered after blunt trauma to the eye. Most iris detachments are small, superior, and asymptomatic and require no surgical intervention. However, large areas of iridodialysis require early surgical repair to prevent the onset of iris necrosis, pigment dispersion, and secondary glaucoma. Suture fixation of iris to the sclera is the most commonly used method for iris repair; however, this technique becomes difficult in cases of near-total iris disinsertion, even in expert hands. We describe a case of posttraumatic near-total iris disinsertion with subluxated cataract managed with phacoemulsification and iris preservation with the help of intracameral injection of isoexpansile sulfur hexafluoride.
