Deep anterior lamellar keratoplasty and penetrating keratoplasty in macular corneal dystrophy: comparison of visual and topographic outcomes and complications.

Purposes: This study aims to assess and compare the postoperative visual and topographic outcomes, complications, and graft survival rates following deep anterior lamellar keratoplasty and penetrating keratoplasty in patients with macular corneal dystrophy.

Methods: In this study we enrolled 59 patients (23 male; and 36 female) with macular corneal dystrophy comprising 81 eyes. Out of these, 64 eyes underwent penetrating keratoplasty, while 17 eyes underwent deep anterior lamellar keratoplasty.

Comparison of topographic outcomes between HPMC based and vitamin E TPGS based riboflavin solutions after corneal cross-linking.

Purpose: To compare the visual and topographic results between patients who underwent epithelium-off cross-linking using riboflavin solutions compounds hydroxypropyl methylcellulose (HPMC) 1.1% and D-alpha-tocopheryl polyethylene-glycol 1000 succinate (VE-TPGS).

Methods: In this study, 37 eyes treated with HPMC and 29 eyes treated with VE-TPGS were evaluated retrospectively.

Evaluation of Corneal Parameters and Meibomian Gland Alterations After Corneal Cross-Linking in Patients With Progressive Keratoconus.

Objectives: The aim of the study was to evaluate the changes in corneal parameters and meibomian gland alterations after corneal cross-linking (CXL) for progressive keratoconus.

Methods: Thirty nine eyes of 39 keratoconus patients were treated with CXL. Corneal topography, specular microscopy, the Ocular Surface Disease Index© (OSDI), noninvasive tear break-up time (NITBUT), and meibography indices were evaluated preoperatively and at the first, third, and sixth months after CXL.

Evaluation of corneal and lens densitometry with Pentacam HR in children with Nephrotic Syndrome: A controlled, prospective study.

Background: This study aimed to compare the corneal and lens densitometry values between children with Nephrotic Syndrome (NS) and healthy individuals.

Methods: This cross-sectional comparative study included 23 patients with NS and 26 healthy controls. Corneal topographic and corneal and lens densitometric values were measured using Pentacam HR.

Evaluation of meibomian gland morphology and anterior segment parameters by Sirius topography systems in polycystic ovary syndrome.

Purpose: To compare findings in specular microscopy, corneal topography, and noncontact meibography in polycystic ovary syndrome (PCOS) patients with healthy controls.

Methods: A total of 40 women with PCOS and 32 healthy controls were enrolled in the study. Schirmer's test, Ocular Surface Disease Index (OSDI), noninvasive tear break-up time (NITBUT), the mean keratometry (Km), maximum keratometry (Kmax), central (CCT), thinnest (TCT) and apical (ACT) corneal thicknesses, meibomian gland (MG) loss, meiboscores, morphology of MGs, endothelial cell density (ECD), coefficient of variation (CV), and percentage of hexagonal cells (PHEX) were analyzed.

Optical Coherence Tomography and Optical Coherence Tomography Angiography Findings in Multiple Sclerosis Patients.

In addition to ocular neurodegeneration in multiple sclerosis (MS), accompanying microvascular changes in the retina are thought to occur. In this study we sought to compare retinal neurodegenerative changes using optical coherence tomography (OCT) and microvascular changes using OCT angiography (OCTA) of MS patients and healthy controls. This cross-sectional study included 164 eyes of 83 MS patients and 114 eyes of 57 healthy control subjects.

Applications of different types of gas-permeable contact lenses in keratoconus and their visual results.

Purpose: To show applications of different types of gas-permeable contact lenses in patients with keratoconus and to compare visual acuity (VA) results.

Methods: A total of 229 eyes of 133 patients who used different types of rigid gas-permeable contact lenses between April 2003 and April 2010 at the Cornea and Contact Lens Unit of Eye Clinic 2 of the Ministry of Health, Ulucanlar Eye Training and Research Hospital, were included. Visual acuity of patients was classified as uncorrected and corrected with eyeglasses and corrected with contact lenses.
