[Clinical features of aniridia].

OBJECTIVE

To explore the various clinical features of aniridia and its treatment.

METHODS

It was a retrospective case series. All the 8 cases of 16 aniridia patients in our department from January, 1984 to January, 2007 were assayed. All the patients were bilateral aniridia suffering from abnormal vision and manifested with various degree of cataract, 5 eyes manifested with refractory glaucoma, 8 eyes with horizontal nystagmus. These patients underwent cataract extraction and intraocular lens implantation, trabeculectomy, ciliary process laser photocoagulation, in some of patients glass and cover strabismus exercise, color contact lens therapy were applied.

RESULTS

Vision acuity in all of patients with severe cataract were improved after cataract surgery. One glaucoma eye underwent trabeculectomy, but failed to control the IOP and then received ciliary process laser photocoagulation. Three glaucoma eyes only underwent ciliary process laser photocoagulation, 1 eye received topical anti-glaucoma eye drops. The IOP of 3 eyes was controlled. However, the IOP of 2 eyes was not to be controlled. Vision acuity was improved in 4 strabismus eyes after wearing glass and strabismus exercise, the symptom of photophobia was disappeared in 2 eyes after wearing a pair of color contact lens.

CONCLUSION

Although it is hard selection to select the proper treatment for aniridia, most of the cases can obtain a better vision, and relief of the symptom after proper treatment.
