Surgery for drug causing ciliary-block glaucoma

Abstract

Objective To study clinical characteristic of drug causingciliary-block glaucoma,to evaluate the therapeutic effect of surgery for drug causing ciliary-block glaucoma. Methods The clinical informations of 12cases( 12 eyes) of drug causing ciliary-block glaucoma diagnosed in our hospital between April 2001 and December 2008 were evaluated, vistaed summary. Results ①Intraocular pressure (IOP) :Being hospitalized,the IOP of patients was 43.38 ～ 81.78 mm Hg, the mean was (51.66 ± 5.46 ) mm Hg; After treating for 10 ～ 14 days, the IOP of 12 patients were controlled below 25 mm Hg. Following up 12 months, two patients kept their IOP at about 20 mm Hg by using eye-drops; The other 10 patients performed an operation, the IOP of 6 patients were controlled at about 20 mm Hg without giving medicine; Three patients were 21 ～ 25 mm Hg, their IOP wascontrolled at 20 mm Hg after giving β-receptor block medicine. The IOP of one patient was out of control; the patient lost his eye' s functioning after performing the operation. ②Vision: Before treating patients, they had light sense or vision up to 0. 3 in one meter distance ( after being corrected defects of vision). After treating patients,the best-corrected defects of vision were 0. 1 ～ 0. 8. There was a significant difference in vision between before and after treating patients. Conclusion Ciliary-block glaucoma caused by medicine has the same anatomy features as PACG.; The IOP going up was caused by Plocarpine ,The IOP going down was caused by Tropicamidum or Atropine; Vision can be restored through vigorous treating.
