Background/Objective: Hyperphosphatemia is the consequence of end stage renal failure. Inadequate control of serum phosphorus results in elevated Ca×P product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification.  In this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis patie...

Central and peripheral nervous system involvement may occur during the course of Behçet’s disease (BD). In vivo corneal confocal microscopy (CCM) can detect corneal small fiber damage and immune cell density. The aim of this study was to assess central corneal sensitivity, corneal subepithelial nerve plexus morphology and dendritic cell (DC) density in patients with BD. Forty-nine consecutive p...

BACKGROUND/AIM Retinal nerve fibre layer thickness (RNFLT), as measured with scanning laser polarimetry using the fixed angle corneal polarisation compensator (SLP-F), has been found to be reduced after uncomplicated laser assisted in situ keratomileusis (LASIK) compared to the pre-LASIK measurement. Since this virtual RNFLT thinning is attributed to the corneal changes induced by the LASIK, th...

PURPOSE To identify an optimal customized ablation strategy in the treatment of eyes with secondary irregular astigmatism. METHODS Corneal anterior surface elevation maps of 50 eyes with secondary irregular astigmatism after decentered laser in situ keratomileusis (LASIK) or photorefractive keratectomy (PRK) and 50 virgin eyes were used for customized ablation simulations. Two ablation simula...

purpose: to analyze the results of scanning slit topography (orbscan ii, bausch & lomb) in both eyes of patients with unilateral fuchs’ heterochromic iridocyclitis methods: an intra-subject non-interventional case-control study was conducted on patients with unilateral fuchs’ heterochromic iridocyclitis (fhi). none of the patients had history of ocular surgery. corneal topographic parameters ob...

Background: Correlations between bone marrow, heart, kidney, liver, skin and lung transplant rejection or survival with human cytokine gene polymorphisms have been described. There are also reports about the role of cytokines and Tumor Necrosis Factors-Alpha (TNF-α) on corneal transplant in animal models. Further studies are needed to clarify the role of cytokines in corneal allograft rejection...

PURPOSE To determine whether cyclosporine (0.05%) can safely and effectively accelerate corneal nerve regeneration after LASIK, thereby facilitating faster recovery of corneal sensitivity. METHODS This prospective, randomized, single-center clinical study comprised 44 eyes of 22 patients scheduled to undergo bilateral LASIK. One eye was randomly assigned to receive cyclosporine drops twice da...

OBJECTIVE The aim was to compare the corneal topography and tomography parameters of macular corneal dystrophy (MCD), granular corneal dystrophy (GCD) and lattice corneal dystrophy (LCD) patients obtained by Scheimpflug imaging system. METHODS The charts, photographs and topography images of patients were reviewed retrospectively. This study included 73 eyes of 73 patients (28 MCD, 20 GCG and...

PURPOSE To evaluate the relationship between the in vivo confocal microscopic (IVCM) morphology of subbasal corneal nerves, corneal sensitivity, and clinical parameters in patients with non-Sjögren dry eye disease (NSDD). METHODS Forty-three patients with NSDD and 14 healthy age- and sex-matched control subjects were included. Each patient underwent an evaluation of ocular surface disease sym...

BACKGROUND Central corneal thickness (CCT) is an important indicator of corneal status. Its measurement provides valid information about corneal physiological condition and possible changes associated with diseases, traumas, and hypoxia. It is an integral part for interpretation of intraocular pressure and glaucoma patient management and in prerefractive procedure assessment. OBJECTIVE The ai...
