Common Eye Disease - Cataracts

Cataract is a clouding of the lens in the eye that affects vision.  Most cataracts are related to aging.  Cataracts are very common in older people.  A cataract can occur in either or both eyes.  It cannot spread from one eye to the other. When a cataract is small,  the cloudiness affects only a small part of the lens.  You may not notice any changes in your vision. Cataracts tend to "grow" slowly, so vision gets worse gradually.  Over time, the cloudy area in the lens may get larger,  and the cataract may increase in size.  Seeing may become more difficult. Your vision may get duller or blurrier.

Common Eye Disease - GLAUCOMA

Damage to the retinal nerve fibres at the optic nerve head produces characteristic visual loss. Mostly, intraocular pressure increased. (normal IOP:10 – 20mm Hg) Open angle  Glaucoma (IOP above 22mm Hg) - usually no symptom till serious vision loss. Doctors used drops to lower intraocular pressure. If cannot, must go for laser treatment. Closed angle Glaucoma (IOP above 60mm Hg) - One Suffers serious pain in the eye , vision blurred, the eyes are red. Must treat immediately with medication and miotic drop. Long term treatment by surgery - Congenital Glaucoma (very rare) – usually in infants and treated by surgery


Progressive loss of central vision that occurs in elderly patients Wet ARMD - may notice distortion of central vision and blurring progress rapidly - results in colorblindness - either inject drug to prevent from worse but vision cannot be better or, inject drug to improve vision, expensive and up to 2 years treatment Dry ARMD - Vision start to get worse over period of years -Will have problems with reading and any task required detailed vision - no effective treatment but will not lead to total blindness as long the distance vision retain - vision can be improved by LOW VISION AIDS

- The "flying flies" or "dots" that you may sometimes see moving in your field of vision (not serious and usually harmless) - actually tiny clumps of gel or cellular debris inside the vitreous, the jelly-like fluid that fills the inside cavity of the eye - occurs frequently in shortsighted people or in those who have undergone cataract operations - result from the normal ageing process, no treatment or cure for floaters but if a floater appears directly in your line of vision, try moving your eye around - BUT if it develops into a retinal detachment , it will be very serious - any sudden onset of many new floaters or flashes of light should be promptly evaluated by your eye doctor

Common Diseases - FLOATERS

Basic Eye Conditions

MYOPIA (FAR CANNOT SEE) Normally YOUNG KIDS will have MYOPIA more easily than adults. Alot of parents think that if their kids start to wear spectacles, the degree will be more and more higher! It is WRONG CONCEPT! If they don’t have the right degree to see, it will be even worse and cause lazy eye. It will greatly affect the studies!!!! Usually because of prolonged hours of doing homework, computer use and handphones, games, watching tv at very near distance. Parents will have the duty to supervise them from not watching or studying at a very close distance. Normally around 18-20 years old, the condition will start to stablise. If it continue to increase, mostly related to the living habits or job.

PRESBYOPIA (READING PROBLEM) Normally happen around 40 – 45 years old. Because lack of accomodation, cannot see near properly (increase gradually as age grows). A lot of people have wrong idea that they have myopia (-) and will not have PRESBYOPIA. If you wear myopic spectacles, and you are unable to read with it, you have reading problem. If you want to take best care of your eyes, FAR AND NEAR ARE EQUALLY IMPORTANT. If you have MYOPIA, PRESBYOPIA and ASTIGMATISM, don’t be worry!! Its normal!!!

ASTIGMATISM (DOUBLE IMAGE VISION) Normally if one person have astigmatism, he/she might be sensitive to light. Seeing double image on the object. Or cannot focus on the thing he/ she want to see. E.g: 3,8,9 might become 3,3,3 or even 0,0,0. Patient with very high astigmatism, will face more problems than myopic patients. Such as spectacle alignment very important, lens more expensive or even can cause blindness.

1. Every 20-30 mins, rest your eyes and look far objects such as trees, grass etc.. 2)Light condition must be sufficient 3) Do not lie down to read 4) Try to relax your eyes                 5) Maintain a safety distance while doing close work, studying, playing computer games or using phone, watching tv 6) By doing good lens (refer to OPTICIAN)
