Could Triglyceride-Glucose Index, a Predictor of Atherosclerosis, Be Associated with Retinal Vein Occlusion?

Objectives: The triglyceride-glucose (TyG) index is a sign of atherosclerosis in cardiovascular diseases. The TyG index is thought to have clinical significance for the assessment of vascular damage. In this study we aimed to demonstrate the connection between the TyG index and retinal vein occlusion (RVO).

Expression of CD44, PCNA and E-cadherin in pterygium tissues.

Purpose: Pterygium is a common ocular surface disease defined by fibrovascular conjunctival growth extending onto the cornea. However, its pathogenesis remains unclear. This study aimed to determine the role of CD44, proliferating cell nuclear antigen (PCNA), and E-cadherin in pterygium formation and recurrence.

A case report of iridoschisis and cataract: a challenging diagnosis.

Purpose: To report the cataract surgery of a 79-year-old female patient with iridoschisis and senile nuclear cataracts.

Observations: Ophthalmologic examination of the 79-year-old female patient who came to our clinic with complaints of decreased vision in the right eye was observed to have a grade-3 senile nuclear cataract and iridoschisis in quadrants 2-3, 4-7, and 10-11 of the iris in the right eye and a grade-2 senile nuclear cataract and iridoschisis in quadrants 5-7 in the left eye to a lesser extent compared to the right eye. The iris fibrils were not connected to the corneal endothelium.

The role of cyclophilin A and VEGF in the pathogenesis and recurrence of pterygium.

Purpose: Pterygium is defined as overgrowth of abnormal conjunctival tissue on the cornea. Many proinflammatory cytokines and various growth factors have been implicated in the pathogenesis of pterygium. Cyclophilin A (CyPA) is a protein that is used by cyclosporin A (CsA) as the intracellular receptor and is secreted in response to inflammatory stimuli.

Immunoreactivity of ICAM-1, MMP-2, and Nesfatin-1 in lens epithelial cells of patients with diabetes mellitus with or without diabetic retinopathy.

Purpose: The aim of this study was to evaluate the immunoreactivity of matrix metalloproteinases-2 (MMP-2), intercellular adhesion molecule-1 (ICAM-1), and nesfatin-1 in cataract lens epithelial cells (LECs) of patients with diabetes mellitus (DM) and to investigate the relationship of these markers with DM cataract and diabetic retinopathy (DR).

Materials And Methods: Ninety patients were included in the study. The patients were divided into three groups ( = 30): Group 1 (control; patients without DM or DR); Group 2 (patients with DM only), and Group 3 (patients with both DM and DR).

Bcl-2, p53, and Ki-67 expression in pterygium and normal conjunctiva and their relationship with pterygium recurrence.

Purpose: Pterygium is a common lesion of the ocular surface, and its etiology and pathogenesis are still uncertain. This study aimed to investigate the role of apoptosis and proliferation in pterygium formation and recurrence.

Materials And Methods: In this study, p53, Bcl-2, and Ki-67 expression levels were evaluated in primary pterygium ( = 35) and recurrent pterygium ( = 32) tissue samples and compared with normal conjunctiva ( = 30) tissue samples.

Evaluation of the ocular surface by impression cytology in patients with endometriosis.

Objective: The aim of this study was to investigate the effect of endometriosis on the ocular surface.

Methods: A total of 50 patients were included in the study and divided into two groups. Group 1 consisted of 25 patients with endometriosis.

Overexpression of fractalkine and its histopathological characteristics in primary pterygium.

Purpose: This study aimed to evaluate the differences in the expressions of fractalkine in normal bulbar conjunctiva and primary pterygium tissues.

Methods: The study included 48 patients who had been operated on for primary pterygium. Histopathologically, the presence of epithelial atypia, epithelial hyperplasia, goblet cell hyperplasia, epithelial lymphocytic exocytosis, stromal inflammation, mast cell count, and stromal vascularity were evaluated in the primary pterygium tissues.

The Evaluation of TUNEL, PCNA and SOX2 Expressions in Lens Epithelial Cells of Cataract Patients with Pseudoexfoliation Syndrome.

: This study aims to determine the expression patterns of terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL), proliferating cell nuclear antigen (PCNA) and SOX2 in lens epithelial cells (LEC) of cataract patients with pseudoexfoliation syndrome (PEX), and to determine the effect of apoptosis, proliferative activity and stem/progenitor cells on cataract formation in patients with PEX. This is a prospective, randomized clinical trial.: Setting: institutional.

The evaluation of retinal nerve fiber layer thickness in patients with obstructive sleep apnea syndrome.

Aim. To evaluate the retinal nerve fiber layer (RNFL) thickness in patients with obstructive sleep apnea syndrome (OSAS) by optical coherence tomography (OCT). Materials and Method.
