Clinial analysis of causes and treatment of shallow anterior chamber after compound trabeculectomy for glaucoma

Abstract

Objective To analyze the causes and treatments of shallow anterior chamber after compound trabeculectomy for glaucoma. Methods We retropectively analyzed the causes and curative effect of shallow anterior chamber after compound trabeculectomy in 38 eyes (37 cases) in our hospital. Results There were 38 eyes ( 5.57% ) with shallow anterior chamber in 683 eyes after operation of glaucoma in our hospital from 2006 to 2009. The main causes of shallow anterior chamber after trabeculectomy were strong filteration in 18 eyes (42. 15% ), detachment of chorioid in 11 eyes (28.94%), leakage of conjunctival flap in 3 eyes (7.89%), ciliary-block glaucoma in 5 eyes ( 13.15% ), other causes 1 eyes (2.63%). The treatment included medication (cycloplegics, high osmosis drug and corticosteroids) and/or surgery (neoplasty of conjunctival flap, vitrous aspiration and anterior chamber gas injection etc. ). The anterior chamber was established in 32 eyes (84.22%) by drug treatment and in 6 eyes ( 15.78% ) by surgery. Conclusions The main causes of shallow anterior chamber after compound trabeculectomy for glaucoma were strong outflow of aqueous humor, detachment of choroid, leakage of conjunctival flap and ciliary-block glaucoma. Anterior chamber was established by drug treatment in 84.22% of the eyes, and by surgery in only 15.78% of the eyes. Key words: shallow anterior chamber; compound trabeculectomy; causes; treatment
