A common misconception about Glaucoma – which is a form of eye disease leading to optic nerve damage and therefore loss of vision – is that it only affects the elderly. Depending on the specific type of Glaucoma, the disease can develop at any age – even babies can suffer from congenital Glaucoma.
Types of Glaucoma;
Glaucoma can be categorized in many ways: Open Angle versus Angle Closure Glaucoma and Hypertensive versus Normotensive Glaucoma. In general, if there is a problem with the drainage canal of the eye at the angles (be it due to an open angle that becomes obstructed or narrow angles which impede outflow of fluid), too much fluid stays in the eye and causes a rise in the eye pressure.
Open Angle Glaucoma
Open Angle Glaucoma accounts for roughly 90% of Glaucoma cases, and develops slowly over time, often without any pain. The peripheral (side) vision gets impaired first, followed by the central vision. Because of the symptoms and damage are not noticeable, Glaucoma is often referred to as the silent thief of sight.
Angle Closure Glaucoma
Angle Closure Glaucoma is characterized by a sudden increase in intraocular pressure (eye pressure), which causes symptoms like severe eye pain, blurred vision and even nausea. This type of Glaucoma develops very quickly, and requires emergency treatment.
Although Glaucoma is more commonly known to be related to high intraocular pressure (hypertensive Glaucoma), we are realizing that Glaucoma can even occur in patients with normal intraocular pressure (normotensive Glaucoma). This could be due to multiple factors leading to a compromised circulation to the optic nerve despite normal eye pressure. Hence, it is important to be screened for Glaucoma even in those with normal eye pressures.
Early and regular checkup
Vision loss that is caused by Glaucoma is permanent and non-reversible. Coupled with the fact that the disease can be either silent or swift, it is advisable to get your eyes checked early and regularly to ensure early detection.
Why Asia Retina Eye Surgery Centre
At Asia Retina, we provide Glaucoma screening services to determine your risk factors for this diseases. Once we detect that a patient is at-risk, our surgeon will determine the best course of action to manage and slow the progression of Glaucoma. This is done with medication, laser treatment or surgery.
The risk factors for Glaucoma include: 1. Genetic Predisposition If you have a close family member (parent or sibling) who has Glaucoma, it is likely that you have the genetic predisposition for Glaucoma. We would advise Glaucoma screening from the age of 40 years for family members with family history of Glaucoma. Read More...
Glaucoma Screening should be done from the age of 40 years old for those with family members who have Glaucoma; and 50 years old for everybody else. Your visit to our eye clinic will include a check of the following: 1. Your eye pressure. 2. Your eye angles looking for signs of narrow ... Read More...
There are different forms of Glaucoma lasers depending on the type of Glaucoma: 1. Laser Iridotomy – This is a laser performed at the peripheral part of the iris to create a bypass route from fluid to drainage through a crowded, narrow angle. 2. Laser Trabeculoplasty – This laser is targetted at the ... Read More...
There are many surgical options for Glaucoma including: 1. Cataract surgery: Recent studies have shown that cataract removal alone may bring about a lowering of eye pressure because the cataract itself may impede the outflow of fluid at the narrowed drainage canal. For this reason, patients who have cataracts might want to consider ... Read More...
