Ophthalmologist Lau Tze Yan, Teresa explains common causes of impaired vision: macular degeneration

Ophthalmologist Lau Tze Yan, Teresa explains that the yellow spots are located in the central retina in our eyes, once degraded, the central vision will be damaged, hence, seriously affecting daily lives of patients. Ageing, smoking, deep myopia and excessive use of electronic products are factors that pose a high risk to getting macular degeneration.
 
There are two types of yellow spot degradation. Dry degradation is caused by cell degradation, which has no bleeding retina, however, there is no current cure, and the patient can only take the treatment of macular degeneration of nutritional supplements control the disease.
 
Wet macular degeneration develop symptoms like retinal hyperplasia, the regeneration of blood vessels, bleedings. Past therapy includes photodynamic therapy, first treated with intravenous injection of photosensitizer lesions of blood vessels, and then to produce optical effects of laser, the coagulation then stops the radical bleeding. The latest treatment available is anti-vascular endothelial growth factor injection, it can be directly injected into the eyes, inhibiting of abnormal blood hyperplasia, treatment of the general three-pin starts from a needle per month. The two treatments can be used separately or in combination, depending on whether the patient's condition is recurrent or not.
 
The patient must quit smoking, otherwise it will be difficult to keep the condition under control, with risk to relapse. Seniors who do not accept cataract extraction surgery, might mistakenly think that macular degeneration is a cataract, therefore once you encounter eyesight abnormalities, it is best to seek medical treatment and have an official eye examination.
