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.
Peripheral Vision Loss (Tunnel Vision)
Your eyesight peripheral vision refers to your side vision. If you lose this, you will struggle or no longer be able to see objects that are out to the side, or the corner of your eye and aren’t directly in front of you.
