Conclusions: With both methods, reproducibility of the size of the pterygium head was high. Significant differences were shown between the two methods in quantification of the width and length but not in the surface area. Such methods can be used to standardize the evaluation of pterygia in clinical research and clinical trials.

Purpose: To compare corneal biomechanical changes after uneventful phacoemulsification cataract surgery between type 2 diabetic (DM) and nondiabetic patients. Methods: Forty-four diabetic (44 eyes) and 44 (44 eyes) age and sex-matched non-DM controls with age-related cataract were enrolled in this prospective observational study. Corneal hysteresis (CH), corneal resistance factor (CRF), and corneal-compensated intraocular pressure (IOPcc) were evaluated by using the ocular response analyzer; central corneal thickness was recorded by using the Pentacam HR. Patients were evaluated preoperatively and 1 and 6 months after...

Purpose: To compare the central corneal thickness (CCT) measurements measured by using the Pentacam Scheimpflug system with the CCT measured using ultrasound pachymetry (UP) and to compare the compatibility between the methods in normal, keratoconic, and cross-linked keratoconic corneas. Methods: The study included 50 eyes of 50 patients with keratoconus (keratoconus group), 50 eyes of 50 patients with progressive keratoconus who underwent corneal cross-linking treatment (CCL group), and 50 eyes of 50 healthy subjects (control group). Patients in the keratoconus and CCL groups were further classified into mild (mean k...

Conclusion: We found a correlation between the speed of stripping, scroll width, and endothelial cell loss. Slow-peeled Descemet membrane endothelial keratoplasty grafts result in a wider scroll width but were associated with a greater reduction in endothelial cell density.

Purpose: To analyze whether endothelial cell density (ECD) differs between central and paracentral areas after Descemet membrane endothelial keratoplasty (DMEK) and to identify the locations of the highest and lowest ECD. Methods: In this retrospective cohort study, central and paracentral ECDs of 30 eyes of 30 patients who underwent DMEK for Fuchs endothelial corneal dystrophy were evaluated. Central, superonasal, superotemporal, and inferior specular microscopic images were analyzed at 1, 3, 6, 9, and 12 months after DMEK. Changes in ECD by location and over time and changes in location for the highest and lowest EC...

Conclusions: Diagnosing endophthalmitis can be difficult in eyes with advanced microbial keratitis, and the visual outcomes are often extremely poor. Clinicians should have a particularly high index of suspicion in eyes presenting with light perception or no light perception vision, history of cataract extraction, full thickness ulcer or perforation, or choroidal thickening or retinal detachment on ultrasound.

Conclusions: Ethanol can be considered an option for treating P. insidiosum keratitis; however, the exact dose and strength of ethanol which will be most effective needs further work.

Purpose: To evaluate dry eye and quantitative and qualitative changes of meibomian glands with meibography in patients with pemphigus. Methods: Twenty left eyes of 20 patients with pemphigus (group 1) and 20 left eyes of 20 age- and sex-matched healthy volunteers (group 2) were enrolled. Dry eye was evaluated with Oxford scale scoring, tear film breakup time, Schirmer 1 tests, and Ocular Surface Disease Index score assessments. Morphological changes and dropout ratio of meibomian glands were evaluated by upper and lower eyelid meibography (SL-D701; Topcon, IJssel, The Netherlands). Meibomian gland dropout ratio was sc...

Conclusions: Bacterial coinfection is common in patients with Acanthamoeba keratitis. Coinfection did not point toward a worse clinical disease at presentation or outcome.

Purpose: To quantitate corneal haze and analyze the postoperative time course of corneal haze after transepithelial corneal collagen cross-linking (TECXL) in patients with keratoconus. Methods: Patients underwent TECXL and were randomized into 2 groups. One group received intraoperative riboflavin 0.10% every minute, and the second group received riboflavin 0.10% every 2 minutes during ultraviolet exposure. Scheimpflug densitometry was measured preoperatively, and at 1, 3, 6, and 12 months to assess the postoperative time course. Densitometry measurements were also correlated with visual acuity, pachymetry, and topogr...
