Chondroitin sulfate-based composites: a tour d'horizon of their biomedical applications.

Chondroitin sulfate (CS), a natural anionic mucopolysaccharide, belonging to the glycosaminoglycan family, acts as the primary element of the extracellular matrix (ECM) of diverse organisms. It comprises repeating units of disaccharides possessing β-1,3-linked -acetyl galactosamine (GalNAc), and β-1,4-linked D-glucuronic acid (GlcA), and exhibits antitumor, anti-inflammatory, anti-coagulant, anti-oxidant, and anti-thrombogenic activities. It is a naturally acquired bio-macromolecule with beneficial properties, such as biocompatibility, biodegradability, and immensely low toxicity, making it the center of attention in developing biomaterials for various biomedical applications.

Correlation between Age, Gender, Waist-Hip Ratio and Intra Ocular Pressure in Adult North Indian Population.

Introduction: Intraocular pressure (IOP) is affected by various systemic and local factors. The significance of studying the factors affecting IOP is because of its association with potentially blinding condition known as glaucoma.

Aim: Present study was conducted with the aim to find out the correlation between gender, age, Waist-Hip Ratio (WHR) and IOP.

Intra-ocular lens opacification in the anterior chamber leading to loss of vision in an adolescent.

Objective: To report a rare case of intraocular lens (ACIOL) opacification in the anterior chamber in an adolescent and to discuss the possible mechanism of its occurrence and the ways of its prevention.

Case: A 16-year-old male underwent cataract surgery for developmental cataract with placement of a foldable posterior chamber IOL in the anterior chamber. There was subsequent opacification of the IOL, which was replaced by a scleral fixated posterior chamber intraocular lens.

Atypical presentation of ectopia lentis in Marfan's syndrome.

The purpose of this article is to report an unusual bilateral inferior subluxation of the lens in a patient with Marfan's syndrome. A 14-year-old boy presented with gradual painless diminution of vision in both eyes. His family history showed that his maternal uncle also had similar complaints.

Artificial drainage devices for glaucoma surgery: an overview.

Artificial drainage devices (ADD) create an alternative pathway for aqueous drainage from the anterior chamber of an eye through a tube to the subconjunctival bleb connected to an equatorial plate under the conjunctiva. The ADDs, both valved and non-valved, are available for end stage or refractory glaucoma. Currently, some of these devices, particularly the Express shunt, are recommended for the primary treatment of glaucoma.
