Glaucoma is a serious eye condition that damages the optic nerve, which is essential for good vision. It is often called the “silent thief of sight” because it usually develops slowly and without noticeable symptoms in the early stages. If left untreated, glaucoma can lead to permanent vision loss and even blindness.
What Causes Glaucoma?
Glaucoma is commonly caused by increased pressure inside the eye (intraocular pressure). This pressure builds up when fluid in the eye does not drain properly. Risk factors include:
- Age above 40 years
- Family history of glaucoma
- Diabetes or high blood pressure
- Long-term use of steroid medications
- Eye injury or surgery
Symptoms of Glaucoma
In the early stages, glaucoma may not show any symptoms. As the condition progresses, the following signs may appear:
- Gradual loss of side (peripheral) vision
- Blurred vision
- Eye pain or pressure
- Headaches
- Seeing halos around lights
- Redness of the eyes
- Sudden vision loss (in acute cases)
Regular eye check-ups are crucial because vision loss caused by glaucoma cannot be reversed, but it can be prevented from worsening.
Glaucoma should be treated by an Ophthalmologist, a medical doctor specialized in eye diseases. For advanced care, a Glaucoma Specialist—an ophthalmologist with additional training in glaucoma management—provides expert diagnosis, monitoring, and treatment to preserve vision.
