Abstract Details


To know the effect of Cyclophotocoagulation (CPC) in reducing the intra ocular pressure (IOP) of absolute glaucoma.


Armed Forces Hospital, Al Khoudh, Muscat, Sultanate of Oman.


28 cases of absolute glaucoma due to various aetiologies under went CPC in the base hospital. All patients underwent the procedure under peribulbar block. An 810nm diode laser was used with a power range between 1.25 W to 2 W for a duration of 3 secs. Power was titrated based on the audible click and thereafter reduced by 50mw. Post op follow up was done at 1 week, 4 weeks and 16 weeks after the procedure.


Mean age of presentation was 60 years. Absolute glaucoma secondary to primary open angles constituted for majority of the cases (28.57%) whereas central retinal vein occlusion and proliferative diabetic retinopathy constituted the second most common cause (26.32% each). IOP reduction ranged between 8 to 43 mm Hg with a mean reduction of 22.36 mm Hg (48.32%, p < 0.001) in 25 cases at the end of 16 weeks. Average time required for reduction of IOP was 7 weeks. Pressure remained unchanged in 3 cases which required repetition. Patients tolerated the procedure well with minimum post operative complications.


CPC is a safe and effective procedure in cases of end stage glaucoma with minimum side effects.
