Queries/errors: Trabeculectomy with early/late phacoemulsification

摘要

A few points in the informative article by Awai-Kasaoka et al. deserve discussion. First, in Figure 1, the label along the x-axis is "Years after repeat trabeculectomy." The word "repeat" is probably an error. Second, in "Surgical Technique" (subheading "Phacoemulsification"), there is the following sentence: "Antimetabolic agent injections were not given." It is not clear what the authors want to convey. This sentence probably should have been under the subheading "Trabeculectomy." Third, the next sentence says that "[a]ll patients were treated with fluorometholone." Fluorometholone is a weak antiinflammatory drug, and in normal practice, more potent steroids such as dexa-methasone are used. It was especially important to stick to the normal practices as the authors wanted to see the adverse effect of inflammation on the trabeculectomy. Finally, neither the female:male ratio (117:61) nor the etiology of glaucoma: POAG/exfoliation glaucoma ratio (61:117) shown in Table 1 of the article was reported earlier.
