Visual recovery following pituitary adenoma surgery: prognostic value of optical coherence tomography and suprasellar tumour volume.

Objective: The aim of this study is to investigate the effects of preoperative parameters such as retinal nerve fiber layer (RNFL) thickness, visual acuity (VA), visual field (VF), and tumour volume on postoperative outcomes in patients with pituitary adenoma.

Design: Retrospective study.

Participants: Two-hundred and seventy-six eyes from 142 patients were included.

Improvement of Clinical Findings, Meibography and Tear Film Parameters in Pediatric Ocular Rosacea Patients After a Standard Treatment Protocol.

Purpose: The objective of this study was to illustrate the changes in ocular findings, meibography, and tear break-up time (TBUT) values in pediatric patients with ocular rosacea following a standardized treatment.

Methods: The study included consecutive patients diagnosed with ocular rosacea, referred to a tertiary hospital between 2021 and 2023. Each patient underwent biomicroscopic examinations, non-invasive TBUT assessments, corneal fluorescein staining (evaluated using the Oxford scoring system), and meibography.

Conjunctival Microbiota and Blepharitis Symptom Scores in Patients With Ocular Rosacea.

Purpose: Investigation of the relationship between blepharitis-related symptom scores, tear film functions, and conjunctival microbiota in patients with ocular rosacea (OR) compared with healthy controls was aimed.

Methods: Consecutive 33 eyes of 33 patients with OR who were admitted from the dermatology clinic and age-matched and gender-matched 30 healthy controls were included in the study. Tear breakup time (TBUT), Schirmer score, and blepharitis symptom score (BLISS) were recorded for each patient.

Central Corneal Thickness Measurements with Different Imaging Devices: Ultrasound Pachymetry, Noncontact Specular Microscopy, and Tono-Pachymetry.

Objectives: Investigation of the compatibility between central corneal thickness (CCT) measurements in healthy eyes by comparing standard ultrasound pachymetry (USP) with noncontact tono-pachymetry (NCT) and specular microscopy (SM) devices was aimed.

Methods: Forty-five eyes of 45 healthy volunteers aged between 18 and 60 years were included in this study. CCT of all cases was evaluated with USP, NCT, and SM devices.

One step preparation of stable gold nanoparticle using red cabbage extracts under UV light and its catalytic activity.

Herein, we have reported the synthesis, characterization and catalytic activity of highly stable gold nanoparticles (Au NPs) using red cabbage extract (RCE) under UV irradiation. The anthocyanin groups predominantly existing in RCE play an essential role for biosynthesis of stable Au NPs. The reasons for using anthocyanins: 1) they act as chelating agents for preferentially reacting with gold ions (Au) to form Au- anthocyanin complexes, 2) as light-active reductants for reduction of Au to zero valent Au under UV irradiation and 3) as stabilizing agent for preventing Au NPs from aggregation in high salt concentration owing to their unique salt tolerance property.
