Facilitating glaucoma diagnosis with intereye neuroretinal rim asymmetry analysis using spectral-domain optical coherence tomography.

Purpose: To determine whether intereye asymmetry of a three-dimensional neuroretinal rim parameter, the minimum distance band, is useful in differentiating normal eyes from those with open-angle glaucoma.

Materials And Methods: This is a cross-sectional study of 28 normal subjects and 33 glaucoma subjects. Subjects underwent spectral domain optical coherence tomography imaging of both eyes.

Pediatric intraocular pressure measurements: Tonometers, central corneal thickness, and anesthesia.

Measuring intraocular pressure (IOP) is the cornerstone of a comprehensive glaucoma examination. In babies or small children, however, IOP measurements are problematic, cannot often be performed at the slit lamp, and sometimes require general anesthesia. Therefore, it is essential for an ophthalmologist who examines a pediatric patient to be aware of the different tonometers used in children, as well as the effects of central corneal thickness and anesthesia on IOP measurements.

Study of platelet activation, hypercoagulable state, and the association with pulmonary hypertension in children with β-thalassemia.

Background: The increased survival rate of thalassemic patients has led to unmasking of management related complications which were infrequently encountered.

Objective: Study the increased coagulation and platelet activation in children with β-thalassemia, to analyze the factors that lead to such hypercoagulable state and to study pulmonary hypertension (PH) in conjunction with platelet activation and hypercoagulable state in children with β-thalassemia.

Methods: 36 Egyptian children with β-thalassemia with a mean age of 9.
