Glaucoma FAQ
What causes glaucoma?
Glaucoma is primarily caused by increased intraocular pressure (IOP) damaging the optic nerve.
Who is at risk for glaucoma?
Risk factors include age, family history, diabetes, and high myopia (nearsightedness).
Is glaucoma curable?
Glaucoma is not curable, but early treatment can slow or prevent vision loss.
How is glaucoma diagnosed?
Diagnosis involves eye exams, including tonometry (IOP measurement) and optic nerve evaluation.
What are common glaucoma symptoms?
Early stages often have no symptoms; later stages may include vision loss and blind spots.
Can glaucoma be prevented?
Regular eye exams can help detect glaucoma early, but it cannot always be prevented.
How often should I get checked for glaucoma?
Adults over 40 should have regular eye exams every 3-4 years, or as recommended by an ophthalmologist.
What medications lower eye pressure?
Common medications include prostaglandin analogs (e.g., Xalatan) and beta-blockers (e.g., Timoptic).
Are glaucoma medications available in Malaysia?
Yes, various glaucoma medications are available with a prescription from an eye doctor.
Can glaucoma surgery help?
Surgery, like trabeculectomy, may be recommended if medications fail to control IOP.
Does glaucoma affect both eyes?
It can affect one or both eyes, though both eyes are often affected eventually.
Can lifestyle changes help manage glaucoma?
Maintaining a healthy lifestyle, including exercise and weight management, may help reduce IOP.
How does diabetes increase glaucoma risk?
Diabetes can damage blood vessels in the eye, potentially increasing glaucoma risk.
Are there alternative treatments for glaucoma?
Laser treatments (e.g., SLT) are alternatives to medications in some cases.
Can children develop glaucoma?
Yes, though it's rare; congenital glaucoma can occur in infants and young children.
