Cataracts
Cataracts are among the most common age-related eye conditions and a leading cause of blindness worldwide. In fact, their global impact is so significant that a dedicated Cataract Awareness Month is observed each year in June to raise awareness, promote early detection and encourage timely cataract treatment. Whether you are experiencing changes in your eyesight or simply want to learn more about eye cataracts, this guide covers everything from cataract causes and symptoms to cataract surgery and prevention.
Posterior Vitreous Detachment: Causes, Symptoms and Treatment
Posterior Vitreous Detachment or PVD is an age-related eye condition where the vitreous, a gel-like substance inside the eye, separates from the retina. The vitreous fills about 80% of the eye and helps maintain its shape while allowing light to pass to the retina, which is responsible for processing visual information.
Angle-Closure Glaucoma Explained: Causes, Symptoms, Treatment and Prevention
A key part of the mechanism in angle-closure glaucoma (sometimes referred to as narrow-angle glaucoma or closed-angle glaucoma) is the movement of the iris (the coloured part of the eye), which blocks the eye’s drainage pathways. In this condition, the fluid (aqueous humour) continually produced to maintain pressure cannot leave the eye, dramatically increasing intraocular pressure (IOP). If left untreated, the optic nerve degenerates quickly, leading to irreversible vision loss.
