What is the importance of having a regular eye-check performed by an eye specialist?
Regular eye-checks are important to have your vision corrected to improve your quality of life, and to aid in detecting certain eye conditions such as cataracts, glaucoma and age-related macular degeneration that can lead to loss of sight.
What eye diseases can be detected in an early phase by an eye specialist?
The four most common eye-conditions leading to loss of vision or blindness are cataracts (a cloudy area in the lens of your eye, impairing vision), diabetic-retinopathy (high blood sugar levels damaging the back of the eye), glaucoma (optic nerve that becomes damaged, connecting the eye to the brain and resulting in loss of peripheral vision) and age-related macular degeneration (an eye disease that can blur your central vision, causing damage to the macula).
What are the most common, non-age-related eye diseases that are important to check for regularly?
A regular check for refractive errors is good for maintaining good vision and if necessary, to be corrected by glasses or contact lenses.
A check for Myopia (short-sightedness) amongst children is getting more important since they spend more time indoors doing near-focused activities on smartphones etc.
What are the most common symptoms to be aware of that could indicate a threat to vision?
The most common symptoms are red eyes, night blindness, headaches, light oversensitivity, floaters (jelly-like material inside your eyes, obstructing your vision), flashes (bright spots or points of light in your field of vision), dry eyes, excessive tearing, blurred or distorted vision.
What other non-eye-related diseases can be diagnosed with an eye examination?
Aneurysm, a bubble in the wall of a blood vessel can be detected in the eye.
Brain tumor, can create increased pressure in the brain that gets transmitted to the eye, causing changes to the optic nerve resulting in loss of peripheral vision and/or double vision.
Cancers of blood, tissue or skin can also affect the interior aspect of the eye like melanoma, leukaemia and lymphoma (also tumours in the breast and other areas can spread to the ocular structures).
Diabetes causes tiny blood vessels to leak yellow fluid or blood in the eye even before a person has been diagnosed with diabetes.
Heart disease by detecting microscopic marks left behind by an eye stroke.
High blood pressure by detecting unusual bends, kinks, or bleeding from blood vessels in the back of the eye.
High cholesterol by detecting a yellow- or blue ring around the cornea (transparent layer forming the front of the eye).
Stroke by detecting blood vessels that contain blockages or clots in the retina (back side of the eye), causing blind spots that can point to an increased risk for stroke.
Multiple Sclerosis - a degenerative disease that affects the nervous system, an inflammation that causes blurred vision, painful eye movement or even double vision.
Vascular disease by detecting clotting and bleeding in and around the eye that threatens vision by retinal haemorrhages.
How can the most prevalent eye diseases be prevented?
Eye disease, such as age-related macular degeneration, can be avoided by generally aiming to lead a healthy life by not smoking and avoiding ‘secondhand smoking’, to exercise regularly, keeping normal blood pressure and cholesterol levels and eating a healthy diet and the best way to prevent such an eye problem and/ or stopping it from progression is to make regular visits to your eye specialist.
