Abstract Details


This study aims to find out the outcome of trabeculectomy in Primary Open Angle Glaucoma (POAG) in at least 6 months follow-up in terms of intraocular pressure reduction at Takeo Eye Hospital from January 1, 2013 to December 31, 2016.


Takeo Eye Hospital, Takeo province, Cambodia


In this study, 56 eyes (56 patients) with Primary Open Angle Glaucoma (POAG) which underwent trabeculectomy from January 1, 2013 to December 31, 2016 in patients who are over 40 years old were selected. Follow up time was set as at least 6 months. Post-operative complete success was defined as IOP ≤ 21 mmHg without any antiglaucoma drug, qualified success was described as IOP ≤ 21 mmHg with medication, while failure was termed when IOP > 21 mmHg with medication.


There were 56 patients (56 eyes) were selected and came to the data analysis. Among 56 patients, there were 39 (69.64%) female and 19 (30.36%) males. The age ranges from 41 to 69. In total 56 patients, the greatest number of patient came from Takeo province (42.86%) and the provinces or city nearby. At final visit, the study showed complete success rate was obtained in 25 eyes (44.64%), qualified success achieved in 14 eyes (25%), while other 17 eyes (30.36%) failed.


In this retrospective study we can state that trabeculectomy is a surgical method that gave a moderate success rate (44.64%) in terms of IOP outcome. The trabeculectomy with antimetabolite should replace this old technique for a better result in order to improve quality of life of Cambodian patients. We recommend the eye hospitals should officially include the antimetabolite in their trabeculectomy procedure for a better result. We also express an enormous encouragement to all Cambodian researchers to keep good work on researching field, especially trabeculectomy with antimetabolite to make more local studies available.
