Common Eye Problem
The proper function of our eyes are very important and we
Refractive errors ( myopia, astigmatism and hyperopia)
The commonest causes of vision blurring are refractive errors. The 3 common refractive errors are
- Myopia / short sighted. Usually distance vision is blurred but nearer objects are clear.
- Hyperopia/ Long sighted. Usually near vision is blurred but distance objects may be clearer.
- There is distortion on the eye surface and all images are slightly blurred.
Treatment methods include glasses, contact lenses and surgery. Read More
Presbyopia
Presbyopia describes blurring of near vision.
This often starts around the age of 40 years causing difficulty with using computers, handphones, reading and sewing. Even simple tasks like reading the price tags in the supermarket shelves become difficult. Read More
Cataract
Cataract describes the clouding of the lens of the eye causing decreased vision.
Symptoms include blurring of vision, decreased night vision, rapidly changing spectacle power, glare and halos. In some cases, cataracts may lead to angle closure glaucoma. Cataract surgery is the definitive treatment. Read More
Diabetic Eye Disease
Diabetes is a condition where the blood glucose/sugar level is too high.
This may lead to Cataracts, Glaucoma and Diabetic retinopathy. The high glucose levels cause changes to the blood vessels of the retina (the light sensitive membrane at the back of the eye). There will be changes to the blood vessel wall (micro aneurysms), bleeding, leaking of fats and proteins and ischemia (insufficient blood supply to the retina). Management includes screening for early detection, risk management, lasers and surgery in more advanced cases. Read More
Glaucoma
Glaucoma is a condition of relative increased eye pressure.
The increased pressure causes damage to the optic nerve at the back of the eye. There is progressive loss of vision, which starts from the peripheral edge of the visual field. When the disease is more severe, the central vision begins to get affected. The higher the eye pressure, the more rapidly vision is lost. It is often symptomatic but patients may also complain of headaches, blurring of vision, glares, halos and eye pain. Read More
Dry eyes and tearing
This is a chronic disease of the tears and the eye surface, and may be caused by a variety of factors, including hormonal change, age, viewing or occupational habits, ocular surgery, certain ocular and systemic diseases and medications, as well as Meibomian gland disease.
Watery eyes in dry eye condition may be due to reflex tearing. The tear properties under basal conditions may be altered in dry dye so that there is insufficient protection of the ocular surface, resulting in irritation and reflex tearing. Read More
In turning eyelids ( entropion )
Entropion is the in-turning of the eyelid.
The lashes and rough skin can rub on the delicate cornea ( the front surface of the eye) causing irritation, pain and tearing. If the cornea surface is disrupted, the eye would be prone to permanent scaring and infections. This could lead to blindness. Read More
Droopy Eyelids
A Droopy eyelid can be due to weakness of the eyelid muscle or heavy and excess eyelid skin.
It may be due to age but other causes include tumours, injury, inflammation and nerve abnormalities. It is important to assess the cause of ptosis, as the treatment will vary. Read More
Eye tumours
The Eye is the most complex organ in the body.
It comprises of many different types of tissue like bone, muscle, skin nerves and even endocrine glands. Tumours can arise from any structure within the orbit. Often they may cause mass effects with swelling of the orbit contents and protrusion of the eye or as lumps on the eyelid skin. Sometimes they may present as double vision, decreased vision or even tearing. Read More
Age-Related Macula Degeneration
AMD is a chronic problem of the macula ( the part of the eye responsible for sharp central vision).
An accumulation of toxins which may be due to age, smoking and sun exposure , damage the retina cells. There may be bleeding and scarring seen in the retina. There are two forms of AMD: Wet AMD and Dry AMD. Read More
