Purpose: Pterygium is a hyaline degenerative disease of the conjunctiva characterized by the progression of fibrovascular connective tissue from the bulbar conjunctiva to the cornea. The mechanism of pterygium formation is still not fully understood. Transient receptor potential (TRP) channels are a group of ion channels with distinct characteristics.

Around 200 million people have been reported to be affected by the pterygium in the world. Although the risk factors for pterygium are well documented, the molecular pathogenesis of pterygium seems to be very complex and remains highly elusive.

Methods: Forty-five patients were included in this retrospective study. Visual acuity (VA), corneal topography, and auto-refractometer measurements, as well as detailed biomicroscopic examinations, were performed preoperatively and postoperatively.
We present the case of a 31-year-old patient with toxic anterior segment syndrome (TASS) that developed after undergoing deep anterior lamellar keratoplasty (DALK). She had keratoconus, and despite wearing hard contact lenses for many years in the left eye, her vision had deteriorated; therefore, DALK was performed on this eye. The preoperative visual acuity (VA) was finger counting at 3 m.

Methods: Forty-six patients with scleroderma (3 male and 43 female) and 31 healthy controls (6 male and 25 female) were included in the study. Twenty-five patients had limited-type and 21 patients had diffuse-type scleroderma.
PurposeThe purpose of this study was to investigate the outcomes of nasolacrimal duct intubation in the primary treatment of congenital nasolacrimal duct obstruction (CNLDO) in children aged 7 years and older.MethodsThirty children aged ≥7 years who underwent primary unilateral nasolacrimal duct intubation because of CNLDO were enrolled in this study. CNLDO diagnosis was based on signs and symptoms including typical epiphora, increased tear meniscus, recurrent or persistent mucopurulent discharge, and an abnormal dye disappearance test (DDT).

Materials And Methods: In this prospective cross-sectional study, 57 eyes of 57 healthy Turkish subjects were enrolled. Each participant underwent a comprehensive ophthalmic examination and peripapillary CT measurement using EDI-OCT.
Purpose: To evaluate the effectiveness of liquid crystal glasses (LCG) in the treatment of children with monocular amblyopia.
Methods: A total of 14 amblyopic eyes of 14 children with monocular amblyopia were enrolled in the study. LCG with appropriate refractive correction were ordered for each patient.
Background: The aim of this study was to investigate the antioxidant and radioprotective effects of propolis, caffeic acid phenethyl ester (CAPE), Nigella sativa oil (NSO), and thymoquinone (TQ) against ionizing radiation-induced cataracts in lens after total cranium irradiation of rats with single dose of 5-Gy cobalt-60 gamma rays.
Methods: A total of 74 Sprague-Dawley rats were divided into 8 groups to test the radioprotective effectiveness of Nigella sativa oil, thymoquine, propolis, or caffeic acid phenethyl ester administered by either orogastric tube or intraperitoneal injection. Appropriate control groups were also studied.
Purpose: To investigate whether there is an association between penetrating eye injuries and attention deficit hyperactivity disorder (ADHD) symptoms in children.
Methods: 45 children aged 3-18 years who were treated due to penetrating ocular injuries (patient group) and 75 control subjects (control group) were enrolled in the study. The symptoms of ADHD were evaluated by the Turkish adapted and validated form of the Conner Parent Rating Scale (CPRS).
Aim: To investigate choroidal thickness in healthy Turkish subjects.
Materials And Methods: Refraction, axial length (AXL) measurement, anterior chamber, and fundus examinations were performed. Eyes that had any retinal or choroidal pathology were excluded from the study.
Objective: The aim of this study was to investigate the antioxidant and radioprotective effects of Nigella sativa oil (NSO) and thymoquinone (TQ) against ionizing radiation-induced cataracts in lens after total cranium irradiation (IR) of rats with a single dose of 5 gray (Gy).
Materials And Methods: Seventy-four Sprague-Dawley rats were used for the experiment. The rats were randomly divided into six groups.
Objective: To evaluate the visual and refractive outcomes after phacoemulsification surgery in eyes with isolated lens coloboma.
Design: Prospective, consecutive case series.
Participants: Eighteen eyes with isolated lens coloboma of 13 patients were included in the study.
Aim: To investigate ophthalmologic findings in children with thalassemia major (TM) and compare the findings with healthy controls.
Methods: In a cross-sectional study, 43 children with thalassemia major from pediatric hematology outpatient clinics from two university hospitals and age/sex matched 47 healthy children were included in the study. After a complete ophthalmic examination, tear function tests including the Schirmer test, fluorescein tear break-up time (BUT), ultrasound pachymetry, and axial length measurement were performed.
Background: Corrective surgery is done for ocular alignment and disrupted facial expression in some cases of adult strabismus patients. The effects of corrective surgery on the presence of social phobia (SP) diagnosis, the severity of social anxiety symptoms, the disease-related disability and the quality of life (QoL) among strabismus patients have not been thoroughly studied yet.
Methods: The study sample was composed of patients who had undergone corrective surgery for strabismus.
Purpose: Genetic factors are shown to have a role in the development of primary open-angle glaucoma (POAG). The aim of this study was to determine the effects of genetic polymorphisms of Rho-kinase (ROCK) genes on the risk of POAG in a Turkish population.
Methods: Genomic DNA was extracted from leukocytes of the peripheral blood, and 8 single nucleotide polymorphisms in the ROCK1 and ROCK2 genes were analysed in 179 patients with POAG and in 182 healthy controls of similar age by using BioMark HD dynamic array system.
Background And Aim: We conducted a prospective study to investigate the possible relationship between the tortuosity of coronary arteries (TCA) and carotid intima-media thickness (CIMT), and also compare TCA to retinal artery tortuosity.
Methods: One hundred and five participants with nonsignificant coronary plaque or normal coronary angiogram were included. To determine subclinical atherosclerosis, maximum CIMT was measured.
