To evaluate the intraocular pressure reduction effect of combined gonioscopy-assisted transluminal trabeculotomy (GATT) with goniosynechialysis in eyes with secondary synechial angle closure glaucoma.
Patients with secondary synechial angle closure glaucoma
Involving more than 180 degrees of the iridocorneal angle
Requiring surgery for uncontrolled IOP despite maximum tolerated therapy.
Eyes with PACG.
Eyes with neovascular glaucoma. (Some apparently stable NVG cases would have remnants of neo-vessels in the angle that are hidden behind the synechiae).
Eyes with retinal pathology.
Eyes requiring combined phacoemulsification and GATT.

IOP and glaucoma medications.
measurement of intra ocular pressure and documentation of number of anti glaucoma medications post operative
Surgical success.
Surgical success will be defined as: complete if IOP is less than or equal to 21mmHg without medications and qualified success if IOP is less than or equal to 21mmHg with medications. Failure will be the inability to achieve such a pressure, the need for another glaucoma operation or the development of a sight-threatening complication (e.g., retinal detachment, endophthalmitis)
Complications.
rate of complications will be recorded
