Abstract Details

Purpose:

To evaluate the influence of cataract surgery on sequential intraocular pressure measurements as a function of iridocorneal angle width

Setting:

Single center single surgeon study

Methods:

Sequential Goldmann applanation tonometry (GAT) measurements were obtained at 8:00 and 10:30 a.m. and 1:00, 3:30, 6:00, 8:00 and 11:00 p.m. on one single day before and two months after uneventful cataract surgery in 20 eyes of 10 patients (5 m., 5 w., 70.9 ± 10.0 years) with chronic angle-closure glaucoma. The changes of mean intraocular pressure (IOP), standard deviation, minimum and maximum IOP were compared pre- and postoperatively. The results were correlated with iridocorneal angle width as determined gonioscopically by Shaffer and with anterior segment Scheimpflug images.

Results:

The mean preoperative iridocorneal angle (ICA) was 34±9° / 36±10° (nasal / temporal). The mean postoperative ICA was 50±9°/51±5°. The mean preoperative IOP was 19.4±5.5 mmHg, the mean minimum and maximum IOP was 16.9±5.9 and 22.2±6.6 mmHg. The mean postoperative IOP was 15.4±3.1, the mean minimum and maximum IOP was 13.4±2.8 and 17.8±3.7 mmHg respectively. The mean application of topical antiglaucomatous therapy dropped from 1.6±1.1 drugs preoperatively to 1.5±1.2 postoperatively. Pearson correlation coefficient between mean IOP change and mean preoperative iridocorneal angle was 0.46.

Conclusions:

Detailed examination of the iridocorneal angle parameters may help to predict the IOP lowering effects of cataract surgery in patients with chronic angle-closure glaucoma. In these patients, cataract surgery leads to lower mean IOP readings as well as to a lower IOP range in one day sequential measurements .
