Glaucoma is a group of eye conditions that lead to damage of the optic nerve, often associated with increased intraocular pressure. It is one of the leading causes of irreversible blindness worldwide. The condition typically progresses slowly and may not present noticeable symptoms until significant vision loss occurs. Early detection and management are crucial in preserving vision. Advances in glaucoma medicine have led to a variety of treatment options, including medications such as prostaglandin analogs, beta-blockers, and alpha agonists, as well as laser therapies and surgical interventions. Ongoing research continues to explore innovative approaches to improve diagnosis, treatment, and patient outcomes, emphasizing the importance of regular eye examinations for at-risk populations.
