Glaucoma results in irreversible damage to the optic nerve of the eye that can result in blindness. It is therefore recommended that patients have regular eye examinations. Effective treatments are now available including topical medications, laser (SLT and PI) and glaucoma filtering surgery.
Selective Laser Trabeculoplasty (SLT) is a highly effective laser procedure that reduces intraocular pressure (IOP) in glaucoma patients. It improves the drainage of the eye and thereby reduces IOP. It is a convenient, painless and repeatable procedure that usually takes 5 to 10 minutes. The effect usually lasts several years.
A pterygium is a triangular growth that covers the cornea (the clear part of the eye). Unlike a cataract, a pterygium can be seen in the mirror passing over the edge of the coloured iris. It is usually related to eye dryness and exposure to sunlight. To prevent the growth of a pterygium, wrap around sunglasses should be worn outdoors with regular lubrication. Surgery may be indicated for individuals with a growing pterygium or who experience discomfort or irritation. As the factors which caused the original pterygium growth tend to persist after surgery, there is a significant recurrence rate even with the best of surgeries.
