Glaucoma is a common eye condition where the optic nerve, which connects the eye to the brain, becomes damaged. It's usually caused by fluid building up in the front part of the eye, which increases pressure inside the eye. Glaucoma can lead to loss of vision if it's not diagnosed and treated early. Glaucoma does not usually cause any symptoms to begin with. It tends to develop slowly over many years and affects the edges of your vision (peripheral vision) first. For this reason, many people do not realise they have glaucoma, and it's often only picked up during a routine eye test. If you do notice any symptoms, they might include blurred vision, or seeing rainbow-coloured circles around bright lights. Both eyes are usually affected, although it may be worse in 1 eye.

Scleritis is a chronic inflammatory condition that primarily involves the episclera and sclera. Fifty percent of patients with Scleritis are diagnosed with an associated systemic disease including auto-immune conditions and infections. The inflammatory process may extend to adjacent structures, causing several complications that may lead to loss of vision. Topical eye drops are ineffective in this condition. Systemic administration of Non-Steroidal Anti- Inflammatory Drugs (NSAIDs), corticosteroids, non- steroidal immuno-suppressive agents, or a combination of these drugs, is the mainstay of treatment given for Non-infectious Scleritis. Though these therapies are beneficial, can lead to serious adverse effects. Systemic corticosteroids are often accompanied by a poor safety profile characterized by multiple adverse effects, such as fluid retention, hypertension, hyperglycaemia, greater susceptibility to infections, mood changes, osteoporosis, psychosis etc.

Dry eye disease is a common condition that occurs when your tears aren't able to provide adequate lubrication for your eyes. Tears can be inadequate and unstable for many reasons. For example, dry eyes may occur if you don't produce enough tears or if you produce poor-quality tears. This tear instability leads to inflammation and damage of the eye's surface. Dry eyes feel uncomfortable. If you have dry eyes, your eyes may sting or burn. You may experience dry eyes in certain situations, such as on an airplane, in an air-conditioned room, while riding a bike or after looking at a computer screen for a few hours. Treatments for dry eyes may make you more comfortable. These treatments can include lifestyle changes and eye drops. You'll likely need to take these measures indefinitely to control the symptoms of dry eyes.

Refractive errors are a type of vision problem that makes it hard to see clearly. They happen when the shape of your eye keeps light from focusing correctly on your retina (a light-sensitive layer of tissue in the back of your eye). Refractive errors are the most common type of vision problem. There are 4 common types of refractive errors: 1) near-sightedness (myopia) 2) Farsightedness (hyperopia) 3) astigmatism 4) Presbyopia. The most common symptoms include Double vision, Hazy vision, seeing a glare or halo around bright lights, Squinting, Headaches, Eye strain (when your eyes feel tired or sore), Trouble focusing when reading or looking at a computer.
