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.
Background: This study aims to investigate the compatibility of central corneal thickness (CCT) measurements obtained with spectral-domain optical coherence tomography (SD-OCT), Scheimpflug-Placido-based corneal topography (CT), non-contact specular microscopy (NCSM), and ultrasonic pachymetry (UP). These four corneal measurement techniques have not been compared in a single study on these many subjects.
Methods: CCT was measured in 185 eyes of 185 volunteers with each of the four devices by a single observer.
Background: Optical coherence tomography angiography (OCT-A) allowed visualization of capillary level of retina; however, the relationship between coronary vascular status and retinal microvascular changes in patients with apnea is not known well. Our aim was to assess the retinal OCT-A parameters in patients with ischemia and angiographically proven microvascular disease and compare them with obstructive coronary disease in patients with apnea.
Methods: Our observational study included 185 eyes of 185 patients, 123 eyes of patients with apnea (72 eyes from mild OSAS, 51 eyes from moderate to severe OSAS) and 62 eyes from healthy controls.
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.
Photodiagnosis Photodyn Ther
December 2022
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.
Purpose: The purpose of this study was to investigate the presence of viruses in postmortem nasopharyngeal swabs and ocular tissues of patients with coronavirus disease 19 (COVID-19) confirmed through an antemortem reverse transcription polymerase chain reaction (RT-PCR) test.
Methods: We recorded demographic data, comorbidities, treatments, and vaccination status of the patients diagnosed with COVID-19 and monitored in the intensive care unit. Nasopharyngeal swab samples were collected from the patients within 2 hours postmortem followed by swabs from both eyes, lower and upper conjunctival sacs, corneal epithelial layer, and samples from anterior chamber fluid.
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.
Evaluation of corneal and lens densitometry in children with familial Mediterranean fever.
Photodiagnosis Photodyn Ther
September 2022
Background: This study aimed to investigate the presence of subclinical inflammation in the eye by examining corneal and lens changes in children with familial Mediterranean fever (FMF) and provide the regulation for follow-up and treatment protocols according to the presence of signs of inflammation.
Design: This is a cross-sectional, case-control study.
Methods: Topographic parameters and corneal and lens densitometry of 48 patients with FMF (10.
Purpose: To compare the morphological features of the bony nasolacrimal canal (NLC) in Caucasian adults with and without primary acquired nasolacrimal duct obstruction (PANDO).
Methods: The study included one eye each from 38 patients with PANDO and 38 age- and gender-matched controls without PANDO, all of whom underwent multidetector computed tomography. In tomographic images, length, and orientation angles of the NLC, transverse canal diameters at the duct entrance and lower end, and minimum (narrowest) transverse and anterior-posterior canal diameters were measured.
Objectives: This study was designed to investigate the long-term effects of intravitreal anti-vascular endothelial growth factor (VEGF) injections on ocular surface and anterior segment parameters. A comparison was performed of the treated eye and the fellow healthy eye.
Methods: The study group included patients who had received at least 3 intravitreal injections of anti-VEGF agents (bevacizumab, ranibizumab, or aflibercept) for retinal vascular disorders.
Purpose: The aim of this study was to detect early retinal vascular changes with optical coherence tomography angiography (OCTA) in type 1 diabetes mellitus (T1DM) patients without diabetic retinopathy and to evaluate the correlation of the results with carotid intima-media thickness (IMT).
Design: This is a case-control and cross-sectional study.
Methods: This study included 38 adult patients with T1DM, and 38 age and gender-matched healthy controls.
Objectives: This study aimed to investigate the relationship between nasal septal deviation and paranasal abnormalities in the etiology of primary acquired nasolacrimal duct obstruction (PANDO).
Methods: A total of 37 (8 men, 29 women) patients (48 eyes with PANDO) between the ages 20 and 77 years (mean age, 52.8 ± 13.
Objectives: This study aims to investigate the effects of inferior turbinate outfracture on the nasolacrimal system and tear flow.
Methods: Forty-seven patients (26 males, 21 females) between the ages 18 and 52 years (mean age-29.0 ± 9.
