1. Early Intraocular Pressure Rise After Phacoemulsification In Non-Glaucomatous And Eyes With Primary Open-Angle Glaucoma Milos Todorovic 1, Suncica Sreckovic 1 1Clinical Center Kragujevac, Kragujevac, Serbia
Purpose: To examine the changes in intraocular pressure in the early period after phacoemulsification surgery in non-glaucomatous eyes and eyes with primary open-angle glaucoma
Methods: The randomized prospective clinical study included 30 eyes of 30 patients with primary open-angle glaucoma (POAG) and 30 control eyes age-matched patients who underwent phacoemulsification surgery. Intraocular pressure (IOP) was measured preoperatively as well as 4, 24 hours and 7 days after phacoemulsification.
Results: POAG group showed statistically significant differences (p<0.05) preoperatively mean value of IOP (18.16±5.151 mmHg) in comparison to control group (15.06±2.414 mmHg). Four hours after surgery IOP rise was detected in POAG group with mean values 28.00±8.307 mmHg and control group 22.06±6.321 mmHg, these values were also statistically significant (p<0.05). After 24 hours and seven days mean values of POAG group and control group show that there is no statistically significant difference between compared groups.
Control group/ POAG(mmHg)
Conclusion: The intraocular pressure rise after phacoemulsification was detected in every eye. Furthermore, since the normalization of IOP seems to occur within 24 hours after surgery, it may be prudent to measure IOP a few hours after surgery in patients with glaucoma. Although patients without optic nerve damage seem to tolerate transient increases in IOP without problems, we must be aware and understand the various treatment options for elevated intraocular pressure for patients with optic nerve damage. It is necessary to carefully observe IOP leaps and their influence on postoperative visual acuity.
