Glaucoma refers to a group of eye conditions that can damage the optic nerve and gradually affect vision. Symptoms vary by type, with some forms developing without warning signs and others causing sudden discomfort or vision changes. Here is more information on the different types of glaucoma and the symptoms associated with each:
Open-Angle Glaucoma
Open-angle glaucoma is the most common form that develops slowly over several years. The eye’s drainage system becomes less efficient, and fluid pressure builds up gradually while the drainage angle stays open. People often notice nothing at first, which is why routine screening plays a key role in detecting it. Peripheral, or side, vision usually fades before central vision, and this slow pattern makes the condition easy to miss. Regular eye exams help track subtle changes before they widen. Watch for these early signs:
- Gaps in side vision: Small blank spots may appear at the edges of your view.
- Frequent squinting: You may strain more often to see clearly in certain conditions.
- Trouble with low light: Dim rooms can feel harder to navigate than before.
Angle-Closure Glaucoma
Angle-closure glaucoma differs sharply from the open-angle form, and it can appear quickly. The drainage angle becomes blocked, pressure increases quickly, and the change produces noticeable symptoms within hours. This type requires prompt professional attention.
People report severe eye pain, and some experience halos around lights or blurred vision that occurs suddenly. Headache, nausea, and eye redness sometimes accompany these symptoms, making the episode hard to ignore. A rapid pressure spike is an urgent situation, so quick action matters.
Normal-Tension Glaucoma
Normal-tension glaucoma challenges a common assumption; it shows that high pressure is not the only cause of optic nerve damage. In this form, the nerve sustains damage even though eye pressure stays within a typical range. Careful monitoring becomes fundamental, and screening helps detect it. People may not feel discomfort, and changes can remain quiet until the condition progresses. Regular exams that measure the optic nerve and visual field give a clear view of what is happening.
Secondary and Congenital Glaucoma
Secondary glaucoma develops from another cause, and this can include an eye injury, certain medications, or an existing medical condition. The added factor affects fluid drainage or pressure, and the resulting symptoms often overlap with the primary types. Identifying the underlying cause helps guide the right monitoring approach. Congenital glaucoma appears in infants and young children, and parents may notice distinct signs early. The following signs call for prompt evaluation by a specialist:
- Cloudy eyes: The front of the eye may look hazy rather than clear.
- Excess tearing: The child may tear up without an obvious reason.
- Light sensitivity: Bright settings may cause visible discomfort.
- Enlarged eyes: One or both eyes may appear larger than expected.
