Aim: To compare refraction and keratometry readings between premature and term babies at 40 weeks’ postconceptional age (PCA), and the possible effect of birth weight (BW) and gestational age (GA) on ocular parameters. Methods: 33 preterm babies hospitalised in the neonatal unit between January and March 2002 were matched with 33 term babies born within the same period and hospitalised in the s...

Abstract. This paper describes the current state of research and development of a system for the partial automation of quantitative Funduscopy. Image processing techniques are used to segment the optic disk and estimate the parameters of the circumference associated with it. The global objective is to facilitate the diagnosis of pathologies like Systemic Arterial Hypertension and Diabetes Melli...

METHODS. Immunolocalization and Western blot analysis of retinas and ARPE19 cells were performed to examine the expression of 1 1 integrin in the RPE. Retinal abnormality was assessed by funduscopy, histology, and transmission electron microscopy. Progressive retinal damage was quantified by direct counting of rod photoreceptors. Light-induced translocation of arrestin and -transducin was docum...

A case in which a malar fracture was associated with Purtscher's retinopathy with its accompanying impairment of vision is described. The literature concerning this uncommon condition is reviewed and its aetiology discussed. This case reinforces the importance of visual acuity testing and funduscopy following maxillofacial trauma, not only at presentation but throughout the patient's management.

PURPOSE Differential diagnosis between acute optic disc edema (ODE) and optic disc pseudoedema (PODE) may be a clinical challenge even for well-trained ophthalmologists. Funduscopy remains the first-line investigation. The aim of this study was to assess the accuracy, sensitivity, and specificity of funduscopy in differentiating ODE from PODE. METHODS This was an observational, cross-sectiona...

Methods: Seventy two children exposed to mercury vapor and 42 healthy controls were enrolled in the study. Full ophthalmologic examination including best corrected visual acuity, external eye examination, a slit-lamp examination, funduscopy, intraocular pressure measurements, Visual Field (VF), Visual Evoked Potential (VEP) and Color Vision (CV) tests were performed at the presentation and afte...
