Cataracts

Cataracts are a cloudiness that forms in the lens of the eye. Most cataracts are a result of ageing as well as long-term exposure to UV light (sun light) without wearing sunglasses. They may also be caused by eye trauma and some medications. Cataracts generally progress with time, resulting in blurry vision and sensitivity to glare. Cataracts are able to be surgically removed with a relatively minor day surgery procedure where the hazy lens is removed and replaced with a clear plastic lens.

Glaucoma

Glaucoma is a condition in which the nerve fibres that transfer information from the eye to the brain become damaged. Glaucoma is sometimes called the sneak thief of sight as the loss of vision is slow and a considerable amount of peripheral or side vision is lost before you become aware of it. In most people, glaucoma is caused by raised fluid pressure inside the eye - this is always checked in a comprehensive eye examination. If left untreated, glaucoma will lead to blindness as the vision lost is irreversible. There is no cure for glaucoma, but treatments can successfully control its progress in most cases. Some types of glaucoma are hereditary.

Macular Degeneration

Macular degeneration is the leading cause of blindness and severe vision loss in people over 50 years of age. The macula is the central portion of the retina (nerve layer at the back of the eye) and is responsible for your central, high definition vision used to read, recognise faces, drive and see colours properly. Macular degeneration results in loss of central vision, but peripheral or side vision is unaffected. Early detection is vital in macular degeneration as the success of treatments is better in the early stages. At Menai Eye Care, we photograph each patient's macula in a comprehensive eye examination.

Diabetic Retinopathy

Diabetes, being a disorder of the blood can be seen in the blood vessels that are present in the retina (nerve layer in the back of the eye). Damage to the retinal blood vessels is one of the earliest signs of diabetes, and is sometimes found before a person even knows he/she has diabetes. Poor control of blood sugar levels leads to diabetic changes in the eye, in turn leading to loss of vision and even blindness. Diabetes also increases your risk of suffering other eye diseases, so people suffering from diabetes are recommended to have an eye examination every year. At Menai Eye Care, we dilate the pupil of the eye with drops to ensure a thorough examination, photograph the retina and send a report of your results to your doctor.

Pterygium

Pterygium is a fleshy growth that occurs over the conjunctiva (white of the eye) and may encroach onto the cornea (front surface of the eye covering the coloured iris). Pterygia are caused by exposure to UV light (sunlight) without adequate protection (broad brimmed hat and sunglasses). The damage to the eye may begin in the childhood years, although the pterygium may only become visible later in life. If left untreated, a pterygium will cause vision loss as it distorts the cornea and may lead to blindness. A pterygium can be surgically removed and newer techniques mean that there is a very low risk of it re-growing.

Dry Eye

Dry Eye is a condition that commonly affects people of all ages. People with dry eye usually complain of sore or stinging eyes, watery eyes, gritty or scratchy eyes, burning or irritated eyes, red eyes or blurred vision. These symptoms of dry eye occur when the tear film layer (which keeps the eye moist) evaporates too quickly or is not produced in sufficient amounts. Dry eye may also be caused by your environment, ageing, hormonal changes, medications and some medical conditions. Dry eye is commonly treated with lubricating eye drops and/or gels. Recent data indicate that nutritional supplements may also be effective in treating dry eye.
