CASE REPORT A 42 year-old female diagnosed with essential iris atrophy complained of visual decrease in the right eye. Examination revealed moderate corneal oedema, folds in Descemet's membrane, polycoria, corectopia, and iris atrophy. Excimer laser assisted Descemet stripping endothelial keratoplasty was performed, with a good corneal transparency and a significant visual improvement being obt...

Ocular iris metastasis from lung cancer is uncommon. We report a patient with metastatic non-small cell lung cancer who was found to have a metastatic lesion to the iris. Local therapy for pain control and vision loss was administered with intracameral bevacizumab. Complete resolution of pain, improvement in vision, and near complete resolution of iris tumor were seen within two months. No ocul...

Background: The optic nerve damage with the ultimate loss of vision resulting from a clutch diseases named Glaucoma. In many conditions including, corneal dystrophies, edema, and endothelial cornea, important biometric is Central thickness (CCT). Objective: To find difference in mean CCT spectral-domain optical coherence tomography ultrasound pachymetry patients presenting Material & Method...

Purpose: To assess the corneal endothelial morphometry in healthy elderly Hispanic eyes. Methods: A retrospective, cross-sectional, observational, descriptive, and analytical study was designed to central region of endothelium by specular microscopy. total 241 eyes from 125 patients were studied. All included 65 or older (mean: 74.56± 6.74), without ocular disease surgeries. Results: The mean c...

Turbidity measurement for the absolute coagulation rate constants of suspensions has been extensively adopted because of its simplicity and easy implementation. A key factor in deriving the rate constant from experimental data is how to theoretically evaluate the so-called optical factor involved in calculating the extinction cross section of doublets formed during aggregation. In a previous pa...

PURPOSE The aim of this study was to compare 4 methods of central corneal thickness (CCT) measurements in terms of their agreement, repeatability, and measurement time. METHODS CCT was measured in 184 eyes of 92 healthy subjects by the same examiner. The methods used were as follows: noncontact specular microscopy (SM; Topcon SP-3000P; Topcon Corporation, Tokyo, Japan), Pentacam rotating Sche...

BACKGROUND The aim was to compare the repeatability, reproducibility and inherent precision of ultrasound pachymetry (USP), noncontact specular microscopy (SP-2000P) and the Confoscan 4 confocal microscope (z-ring CS4) in measuring endothelial cell density (ECD), coefficient of variation of cell size (CV), and central corneal thickness (CCT) in normal eyes. METHODS In this prospective study, ...
