Glaucoma is often termed the "Silent Thief of Sight" because in its most common form—Open-Angle Glaucoma—it progresses gradually without any early pain, redness, or perceptible warning symptoms until irreversible optic nerve damage has occurred.
Why Glaucoma Causes Vision Loss
Aqueous humor fluid continuously flows within the eye. When the drainage angle becomes restricted, internal intraocular pressure (IOP) rises, gradually compressing sensitive nerve fibers in the optic nerve bundle. Peripheral vision deteriorates first, leading to tunnel vision before central vision is compromised.
Who is Most at Risk?
- Individuals aged 40 and above
- People with a family history of glaucoma
- Patients with Diabetes, Hypertension, or high Myopia
- Prolonged usage of steroid eye drops or medications
- Prior eye trauma or injury
Diagnostic Evaluation & Timely Treatment
A routine comprehensive eye examination including Applanation Tonometry (IOP measurement), Gonioscopy (drainage angle assessment), and OCT Optic Nerve Head imaging is crucial. Detected early, glaucoma can be successfully managed with pressure-lowering drops, selective laser trabeculoplasty (SLT), or filtration surgery.
