Nonsteroidal Anti-Inflammatory Drugs in the Treatment of Retinal Diseases.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are an important class of drugs in medicine and ophthalmology. Several NSAIDs have been commercially available for many years: diclofenac, flurbiprofen, indomethacin, ketorolac and suprofen. The purpose of this chapter is to review the clinical use of earlier and newer pharmacologic agents of the NSAID class.

Macular hole: 10 and 20-MHz ultrasound and spectral-domain optical coherence tomography.

Purpose: Optical coherence tomography (OCT) is valuable for macula evaluation. However, as this technique relies on light energy it cannot be performed in the presence of opaque media. In such cases, the ultrasound (US) may predict some macular features.

Current concepts in vitreomacular traction syndrome.

Purpose Of Review: As Reese first described the vitreomacular traction (VMT) syndrome in 1970, the knowledge base about the disease has been changing over time due to the advent of the high-definition optical coherence tomography (HD-OCT). The aim of this article was to present the current information on the pathophysiology, anatomic macular abnormality associations, treatments, and new concepts in VMT syndrome.

Recent Findings: HD-OCT has provided unprecedented visualization of the vitreomacular interface, which has led to better comprehension of the VMT syndrome.

Impaired glucose tolerance plus hyperlipidaemia induced by diet promotes retina microaneurysms in New Zealand rabbits.

Unlabelled: With the increasing prevalence of diabetes mellitus and metabolic syndrome worldwide, experimental models are required to better understand the pathophysiology and therapeutic approaches to preserve pancreatic beta cells, attenuate atherosclerosis and protect target organs. The aims of this study were to develop an experimental model of impaired glucose tolerance combined with hypercholesterolaemia induced by diet and assess metabolic alterations and target organ lesions. New Zealand male rabbits were fed high-fat/high-sucrose (10/40%) and cholesterol-enriched diet for 24 weeks, when they were sacrificed.

Impending central retinal vein occlusion associated with cilioretinal artery obstruction.

We report a case of a patient with an impending central retinal vein occlusion (CRVO) with cilioretinal artery obstruction, which may help to understand the nature of the retinal hemodynamic changes associated with CRVO which shows direct evidence of arterial vasospasm, suggesting an increased contractility of retinal arteries. The clinical course, with initial retinal whitening along a cilioretinal artery followed by signs of venous stasis, seems to confirm the pathogenesis hypothesis concerning a primary arterial affection due to arterial vasospasm.

Long-term results of photorefractive keratectomy for myopia and myopic astigmatism.

Purpose: To assess the long-term refractive outcomes of photorefractive keratectomy in myopia and myopic astigmatism.

Methods: A retrospective study of 120 photorefractive keratectomy operated eyes with at least four-year follow-up (maximum of 96 months, mean follow-up 55 months). We divided patients into group 1 (G1) spherical equivalent (SE) up to -4.
