We retrospectively analyzed the clinical data of five patients with chronic angle-closure glaucoma who underwent goniosynechialysis (GSL). The patients presented a circumferential synechial angle-closure for less than or up to six months due to an acute primary angle-closure and a minimum six month follow up after GSL. After an average follow-up was of 32.4±13.9 months, visual acuity improved in four (80%) eyes. Before GSL, the intraocular pressure (IOP) varied from 34 to 58 mmHg. After GSL, the IOP varied from 8 to 44 mmHg. IOP was normalized by GSL with or without medication in 80% of the eyes. Before GSL, all patients were on maximum antiglaucomatous treatment including the use of 250 mg of oral acetazolamide three times daily. After GSL, three patients no longer required antiglaucomatous medication and one needed to use one topical antiglaucomatous medication. GSL was effective and safe in four patients and unsuccessful in one patient. An increase of the GSL success rate occurs when it is associated with phacoemulsification and intraocular lens implantation.
