Glaucoma is a leading cause of blindness in adults aged 60 and above. Even though there is no known cure for glaucoma, early detection can preserve your vision. This is why understanding intraocular pressure (IOP) and its role in glaucoma is crucial.
Here’s more on this topic.
What is Intraocular Pressure (IOP)?
Intraocular pressure is the fluid pressure inside your eye. It is essential for maintaining the eye’s shape and proper function. The eye produces a fluid called aqueous humor, which flows through the pupil and drains via a mesh-like channel. When this fluid does not drain properly, it can increase eye pressure, leading to optic nerve damage.
The optic nerve, composed of over a million delicate nerve fibers, transmits visual information from the eye to the brain. When the optic nerve fibers deteriorate due to increased intraocular pressure, blind spots in your vision can develop. These blind spots often go unnoticed initially, as the brain compensates for minor gaps in vision. But, over time, this impairment can become more pronounced.
High IOP: A Risk Factor for Glaucoma
Glaucoma encompasses a range of eye conditions that cause damage to the optic nerve, which is vital for good vision. High IOP is a major risk factor for glaucoma. The optic nerve deterioration can lead to progressive vision loss and, if left untreated, eventually result in blindness.
The Importance of Regular Eye Exams
Regular eye exams are vital for early detection of high IOP and glaucoma. Comprehensive exams often include glaucoma screenings, which can detect elevated IOP before it causes severe damage. Timely detection and treatment can prevent significant vision loss.
Knowing Your Risks
Knowledge of your family’s eye health history is also paramount in the fight against glaucoma. The condition often runs in families. Therefore, if you have family members diagnosed with glaucoma, you are at a higher risk of developing the disease. Consult your eye care professional to determine the appropriate screening schedule for your situation.
Symptoms of Glaucoma
Glaucoma symptoms can differ based on the type and stage of the condition. In its early stages, glaucoma usually presents no obvious symptoms. As it progresses, individuals may experience:
- Blind spots in the peripheral (side) or central vision
- Tunnel vision (in advanced stages)
Since symptoms often go unnoticed, regular eye exams are essential for early detection.
Diagnosing Glaucoma
Accurate diagnosis of glaucoma is a multifaceted process that involves several specialized tests to evaluate the health of the optic nerve and measure intraocular pressure. These tests may include:
- Tonometry – measures the intraocular pressure within the eye
- Ophthalmoscopy – allows for the optic nerve to be assessed for any damage
- Perimetry (Visual Field Test)- to map your visual field to determine if there are any blind spots or vision loss
- Gonioscopy – inspects the drainage angle of the eye, where the iris meets the cornea
- Pachymetry – measures the thickness of the cornea
- Optical Coherence Tomography (OCT) – provides detailed images of the optic nerve and the retinal nerve fiber layer
Through these comprehensive examinations, eye care professionals can make an accurate diagnosis and determine the most appropriate strategy for managing glaucoma, thereby helping to protect and preserve vision.
Glaucoma Management and Treatment
Proactive monitoring and early detection play critical roles in the preservation of vision. If diagnosed with glaucoma, several treatments are available to manage the condition and prevent further damage:
Medications
Controlling IOP is crucial for managing glaucoma. Prescription eye drops and other medications are commonly used to reduce IOP. They work by either reducing fluid production or improving fluid drainage in the eye.
Laser Treatment
Laser trabeculoplasty is a procedure that opens clogged drainage channels, improving fluid outflow and lowering IOP.
Surgery
When medications and laser treatments are insufficient, surgical options are considered. Procedures can include:
- Drainage Tubes: Surgically placed tubes help drain excess fluid from the eye
- Trabeculectomy: An opening is created in the white of the eye (known as the sclera). This surgery aims to create another space for fluid to leave the eye
- Minimally Invasive Glaucoma Surgery (MIGS): Often combined with cataract surgery, MIGS is less invasive than a trabeculectomy. The procedure aims to improve fluid drainage to lower eye pressure
