What Causes Bloodshot Eyes?
4. Glaucoma
Glaucoma is a group of eye disorders where optic nerve damage results in vision loss. It is known as the “silent thief of sight.” It can be divided into open angle, closed angle, and normal tension glaucoma. Open angle glaucoma is the commonest type. The patient is generally unaware as there is no pain and loss of vision develops gradually.
Closed angle glaucoma is considered a medical emergency. Symptoms include severe pain in the eye, bloodshot or red eye, blurry vision, nausea, and vomiting. Early treatment helps to slow or stop the progression of the disease. It often involves the use of medication, laser therapy, or surgery. It is estimated that an estimated 67 million individuals are affected worldwide. Globally, it is the second leading cause of blindness after cataracts.
