Effect of cataract surgery for visual field in glaucoma patients

PURPOSE: To study the influence of cataract surgery on the quantitative and qualitative parameters of visual field in patients previously operated for glaucoma. METHOD: Retrospective study that included 42 eyes with primary open angle glaucoma that had been previously subjected to trabeculectomy. The glaucoma was therapeutically controlled in all patients. Then they all underwent cataract extraction and artificial lens implantation. All eyes were evaluated pre- and postoperatively at short intervals to avoid glaucoma progression. Throughout the follow-up period the IOP remained under 21 mmHg, with or without antiglaucoma drugs. RESULTS: After cataract surgery the visual acuity increased significantly (preoperative VA 0.22 ± 0.15, postoperative VA 0.57 ± 0.27, p < 0.0001). The parameters used for glaucoma evaluation and follow-up remained unchanged (preoperative IOP 17 ± 6.71 mmHg, postoperative IOP 17.04 ± 4.56 mmHg, p = 0.97; preoperative CD ratio 0.59 ± 0.26, postoperative CD ratio 0.62 ± 0.26, p = 0.69). The quantitative parameters of visual field did not change significantly (preoperative MD -15.52 ± 8.69, postoperative MD -13.33 ± 9.97, p = 0.28; preoperative PSD 5.86 ± 3.25, postoperative PSD 6.11 ± 3.39, p = 0.79). In about 60% of cases the MD value improved and in 24% it worsened. The PSD was ameliorated in 33% of cases and aggravated in 26% of cases. CONCLUSION: Cataract surgery in patients with previously operated, therapeutically controlled glaucoma does not influence significantly the synthetic parameters of visual field. LA: Romanian
