Glaucoma gradually progresses with less subjective symptoms. The optic nerve damaging and visual field defect occur very slowly, you won’t even feel any pains.
Exceptionally, there is a case to have heavy eye pain, conjunctivitis inflammations, foggy vision, headache and nausea in order to develop acute glaucoma attack.
Types of glaucoma
- Open-angle glaucoma
The drainage angle formed by the cornea and iris remains open, but the trabecular meshwork is partially blocked.
- Angle-closure glaucoma
Angle-closure glaucoma occurs when the iris bulges forward to narrow or block the drainage angle formed by the cornea and iris. As a result, fluid can't circulate through the eye and pressure increases.
- Normal-tension glaucoma
In normal-tension glaucoma, your optic nerve has damaged even though your eye pressure is within the normal range.
- Secondary glaucoma
Secondary glaucoma occurs to the inflammation of the cornea or uveitis.
- Congenital glaucoma
The drainage angle formed by the cornea and iris has naturally had problem, develops in infancy.
- Developmental glaucoma
The drainage angle formed by the cornea and iris has naturally had problem, develops in adolescent growth.
- Steroid glaucoma
This type of glaucoma could occur to the side effect of steroid.
- Posner-Schlossman Syndrome
Posner-Schlossman is a disease typified by acute, unilateral, recurrent attacks of elevated eye pressure with mild anterior chamber inflammation.
