Abstract Details


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


Single center single surgeon study


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.


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.


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 .
