ABSTRACT
OBJECTIVE:
This study determined the risk of postoperative visual loss and the factors affecting the decrease in visual acuity in patients with advanced glaucoma who underwent trabeculectomy or combined cataract surgery.METHODS:
Charts of patients with advanced glaucoma who underwent trabeculectomy or combined cataract surgery were reviewed for the following parameters visual acuity (VA), intraocular pressure (IOP), and visual-field indices of the Humphrey perimetry. Eyes that lost 2 or more Snellen lines or worsened one category two months after surgery were identified. Central vision was lost (wipeout) when best corrected VA was less than 20/200, characterized as a sudden, permanent, and unexplained visual loss within 2 months post-operatively. Analysis of variance (ANOVA) determined the differences between groups and logistic regression analyzed the factors affecting the decrease in visual acuity postoperatively.RESULTS:
Ninety-eight eyes of 92 patients aged 18 years and older were included in the study. The incidence of postoperative visual loss 2 months after surgery was 20 percent (20/98), of which 3 percent (3/98) was considered "wipeout." Factors affecting the decrease in VA postoperatively include the presence of surgical complications (p = 0.04) and increase in postoperative IOP at two months (p = 0.05).CONCLUSION:
The incidence of wipeout among patients with advanced glaucoma who underwent trabeculectomy or combined cataract surgery is low and generally occurs in patients with central-splitting fixation. Surgical complications play a major role in causing postoperative decrease in VA.
