RESUMO
PURPOSE: To report a case of aniridia in a pseudophakic patient following blunt trauma to the eye. CASE REPORT: The traumatized eye had cataract surgery through a 3.0 mm clear corneal incision 6 years prior to the incident. While there have been previous cases of traumatic aniridia in pseudophakic eyes, previous reports have all occurred closer to the time of the cataract surgery. We believe that the most likely mechanism of loss of iris tissue is through wound dehiscence, which would suggest the relative instability of clear corneal incisions several years postoperatively. The patient's visual acuity returned to 20/20 4 weeks post-trauma, with symptoms of glare which were managed by the use of a colored contact lens. CONCLUSION: The possibility of wound dehiscence should be recognized as an important clinical entity in the immediate postoperative period, but also several years following cataract surgery.
RESUMO
Aniridia is a congenital, often hereditary, usually bilateral absence of iris in whole or in part. And aniridia occurs mainly as an autosomal dominant condition with almost complete penetrance. In the usual phenotype, aniridia is associated with nystagmus, foveal and optic nerve hypoplasia, corneal pannus, cataract, secondary glaucoma and strabismus. The author experienced 4 cases of aniridia in a family for three generations. So the author reports these cases with the review of literathure.
