Acute glaucoma

- caused by a sudden blockage of fluid drainage from the eye, leading to an increase in eye pressure, severe pain and blurred vision. 

- Untreated glaucoma leads to blindness, but can be treated medically or surgically if treatment is started in time.

- Acute glaucoma is rare. It most often occurs in middle-aged and elderly people, but very rarely in people under 40 years of age. 90% of patients with glaucoma are farsighted. In the Nordic countries, 7% of patients with glaucoma have the acute narrow-angle form.

Acute glaucoma


Acute glaucoma always occurs only in one eye, but if you have had acute glaucoma in one eye, there is a greater risk of also getting glaucoma in the other eye.

Impaired vision, and in the worst case, blindness on the affected eye, is a dreaded complication of acute glaucoma.

It starts suddenly and unexpectedly. The patient does not notice anything until after several years.

It tends to develop in the evening or in dark environments. Pay special attention to blurring of vision, as well as pain and rainbow vision when staying in the dark.

Headaches and severe eye pain. Nausea and possible vomiting are also typical. Some may find that their vision is blurred or that they see rainbow-colored rings around light sources. The eye often turns red and there is tearing. 

Prevention - regular check-ups with an ophthalmologist

Without prompt treatment, the condition will lead to blindness in the eye. Even with treatment, some damage to the optic nerve often develops and, as a result, impaired vision. Proper post-treatment can prevent new seizures.

If you experience pain, blurred vision or rainbow vision when staying in the dark, seek eye care.
