Why is it important to detect Glaucoma in the early stages?
Symptoms of glaucoma are very subtle and gradually develop that makes it easy to miss. Many people have no noticeable symptoms in early stages of the disease, which makes it extremely important to have a regular eye exam to detect it in an early stage. Glaucoma nerve damage is irreversible so early detection and treatment is crucial to prevent blindness.
Glaucoma in majority of patients (open angle glaucoma) is detected with symptoms of advanced disease such as patchy blind spots in your side or central vision and tunnel vision in advanced stages.
However, in cases of acute angle closure glaucoma, they may present with severe headache, eye pain, nausea, vomiting and blurred vision.
How can Glaucoma be tested?
- Optic nerve check (through a comprehensive dilated eye exam)
- Gonioscopy (to detect the type of glaucoma)
- Eye pressure check (Tonometry or ocular response analyzer)
- Visual field assessment (to find out sensitivity of the peripheral vision, where glaucoma strikes first)
- Corneal thickness (pachymetry or topography)
- Optic nerve thickness (using Optical Coherence Tomography)
