Understanding Glaucoma: Causes, Symptoms & Why Early Detection is Crucial

Glaucoma is one of the leading causes of blindness worldwide, often referred to as the “silent thief of sight” because it develops gradually and without noticeable symptoms in its early stages. At iCare Centre, we emphasize the importance of early detection and timely treatment to prevent vision loss. In this blog, we will explore what glaucoma is, its causes, symptoms, and why regular eye check-ups are essential.

What is Glaucoma?

Glaucoma is a group of eye conditions that damage the optic nerve, the crucial link between your eye and brain that enables vision. This damage is often caused by increased pressure inside the eye (intraocular pressure or IOP), leading to gradual vision loss if left untreated.

Causes of Glaucoma

Several factors contribute to the development of glaucoma, including:

• Increased Eye Pressure: Elevated intraocular pressure is a significant risk factor for glaucoma, though some people with normal pressure can also develop the disease.
• Genetics: A family history of glaucoma increases the risk of developing the condition.
• Age: Individuals over the age of 40 are more susceptible, with risk increasing as they grow older.
• Medical Conditions: Diabetes, hypertension, and heart disease can elevate the chances of developing glaucoma.
• Eye Injuries or Surgery: Previous eye trauma or certain eye surgeries can contribute to optic nerve damage.
• Prolonged Use of Corticosteroids: Long-term use of steroid medications, particularly eye drops, can increase intraocular pressure.

Symptoms of Glaucoma

Glaucoma progresses slowly, and many patients do not experience symptoms until significant vision loss occurs. The symptoms vary depending on the type of glaucoma:

Open-Angle Glaucoma (Most Common Form)

• Gradual loss of peripheral (side) vision
• Difficulty adjusting to dim lighting
• Blurred vision in advanced stages

Angle-Closure Glaucoma (Less Common but More Severe)

• Sudden vision blurriness
• Intense eye pain and headache
• Nausea and vomiting
• Halos around lights

Normal-Tension Glaucoma

• Damage to the optic nerve despite normal eye pressure
• Similar symptoms to open-angle glaucoma

Why Early Detection is Crucial

Since glaucoma-related vision loss is irreversible, early diagnosis and management are critical in preventing blindness. Regular comprehensive eye exams can detect glaucoma before noticeable symptoms appear.
