Abstract

Background: Rise in intraocular pressure (IOP) is the commonest complication after YAG posterior capsulotomy. As there are different opinions regarding use of anti-glaucoma therapy before YAG, we compared post-YAG IOP between the patients who had Brimonidine eye drops and those who did not have any anti-glaucoma treatment.

Material and methods: It was a prospective study that included patients who had undergone uneventful phacoemulsification with foldable intraocular lens implantation and YAG posterior capsulotomy. One hundred fifty patients were divided into two groups; (a group with prophylactic brimonidine 0.2% eye drops before laser and a group without any anti-glaucoma therapy). Intraocular pressure was checked pre-laser and one hour after laser procedure.

Results: Out of 150 patients, 78 were in brimonidine group and 72 in the control group. The mean age of the patients was 60.39 ± 12.98 years. In the brimonidine group, IOP was 12.56 ± 2.38 mm Hg and 12.29 ± 3.64 mm Hg before and after YAG, respectively. In the control group, IOP was 12.24 ± 1.53 mm Hg and 13.38 ± 2.84 mm Hg before and after YAG. Brimonidine 0.2% caused a decrease in IOP, but the post-laser IOP difference between the two groups was not statistically significant. The change in IOP before and after using brimonidine 0.2% was also not statistically significant.

Conclusion: Every patient undergoing YAG capsulotomy does not require prophylactic anti-glaucoma therapy. Only the patients prone to high IOP, glaucoma suspects, and diagnosed cases of glaucoma should be given prophylactic treatment.
