Abstract Details



Purpose:

To evaluate intraocular pressure (IOP) in patients with primary open angle glaucoma (POAG) 1-2 stages before and 1 month after phacoemulsification (PE) according to the anatomical parameters of the eye.

Setting:

The study included 55 eyes with POAG stage 1-2 and cataract, which was performed PE and 36 is not operated eyes (control group).

Methods:

In all eyes we measure IOP before and 1 month after PE by Maklakov tonometry.

Results:

Among all the operated eyes mean IOP decreased from -19.27 + / -5.24 mm. Hg to 16.76 + / -5.64 (p < 0.05); size of the lens -4.56 + / -0. 61 mm., mean size of eye - 23, 17 + / -1. 42 mm. In 65% cases IOP decreased and in 35%- increased. On eyes with size less than 22 mm. ( 7 eyes ) IOP was 17.28 + / - 4.57 mm Hg, after 1 month- 19.42 + / -9.07 mm. (P> 0,05). On eyes with size 22-23 mm. ( 20 eyes ) IOP was 17.3 + / -5.71 mm. , after 1 month 16.9 + / 5.87 mm. (p> 0,05) On eyes with size more 23 mm IOP decreased from 21.17 + / - 4.44 mm. to 16.03 + / -4.33 mm. Average reduction 5.17 mm. Hg (P <0,05). Size of the lens - 4.46 + / -0.61 mm. In control group IOP not changed.

Conclusions:

Performing PE in patients with POAG is accompanied by changes in IOP, the direction of which depends on the anatomical parameters of the eye, which should be considered when predicting the effect of the operation. FINANCIAL INTEREST: NONE
