[The diagnosis and treatment of the secondary glaucoma caused by epithelial ingrowth into the anterior chamber].
This study reports the clinical manifestations of 3 cases (3 eyes) of the secondary glaucoma caused by epithelial ingrowth into the anterior chamber. Based on some clinically suspected signs, we confirmed the diagnosis of epithelial ingrowth by means of the diagnostic argon laser photocoagulation to make the characteristic white burns in the site of the affected iris. Three eyes with epithelial ingrowth underwent extensive laser photocoagulation on the affected iris by delineating the extent of the epithelial membrane before the therapy. Then excisions of the involved iris and pupillary membrane, anterior segment vitrectomy and trabeculectomy were done on two aphakic eyes. The remaining phakic eye only received the thermal sclerostomy combined with sector iridectomy. The epithelial ingrowth was verified postoperatively by the histopathological examination of the specimens from the excised iris. Optimal reductions in intraocular pressures were observed in two eyes with the epithelial ingrowth of the iris (less than 70%), and in another eye with the extensive involvement of the iris (more than 70%). Medical therapy was required to normalize IOP in addition to the surgical procedure. The follow-up period ranged from 8 to 15 months.
