Objective: Thiazolidinediones (TZDs) are insulin-sensitizing agents that are associated with peripheral edema and have been reported to be associated with diabetic macular edema (DME). We hypothesized that TZDs produce subclinical increases in retinal thickness that may be detected by optical coherence tomography (OCT) but are not seen on routine dilated funduscopic examination.
Research Design And Methods: We used OCT to screen for subclinical DME in a cross-sectional study of patients with type 2 diabetes; 29 patients were taking TZDs and 58 were not taking TZDs.
Purpose: To compare the effect of gatifloxacin and moxifloxacin on visual outcomes after photorefractive keratectomy (PRK).
Methods: Thirty-five PRK patients were treated postoperatively with gatifloxacin (Zymar) in one eye and moxifloxacin (Vigamox) in the fellow eye. Postoperative regimens were otherwise identical.
Purpose: The purpose of this study is to describe a simple method of measuring anterior segment lesions from digital slit lamp images and confirm reliability of the technique.
Methods: Ten reference photos were taken of a PD ruler, refocusing on the ruler for each photo. Using Adobe Photoshop, the number of pixels per millimeter squared (area) and 1 mm (linear) were recorded for each photo.
Purpose: To compare the rate of epithelial healing following photorefractive keratectomy (PRK) with two commercially available fourth-generation fluoroquinolones, gatifloxacin (Zymar, Allergan, Irvine, California) and moxifloxacin (Vigamox, Alcon Laboratories, Fort Worth, Texas).
Design: Double-masked, randomized, prospective trial.
Methods: Thirty-five subjects received gatifloxacin in one eye and moxifloxacin in the fellow eye following PRK with a 9.
