Abstract. Purpose:To report changes in visual field in primary angle-closure glaucoma after control of intraocular pressure(IOP)following surgery. Cases and Method:This retrospective study was made on 37 eyes of 37 cases with primary angle-closure glaucoma. The age ranged from 47 to 79 years,average 68 years. All the eyes had extensive peripheral anterior synechia and IOP averaging 24.0±7.4 mmHg. They received goniosynechialysis. Phakic eyes underwent cataract surgery. Visual field was evaluated by Goldmann perimeter. Results:After the mean follow-up for 7.1±3.7 years,IOP was maintained below 21 mmHg and averaged 14.0±2.7 mmHg. Glaucomatous visual field defect progressed in 10 of 37 eyes(27%). It progressed as complication of normal-tension glaucoma in one of the 10 eyes. Conclusion:Glaucomatous visual field defect progressed in some eyes after IOP control below 21 mmHg following surgery.
