What is a common symptom associated with glaucoma?

Glaucoma is a group of eye diseases that lead to damage of the optic nerve, often associated with increased intraocular pressure. The condition can manifest a range of symptoms, which can vary depending on the type and stage of glaucoma.

Seeing halos around lights is a notable symptom particularly associated with acute angle-closure glaucoma, where elevated eye pressure can cause visual disturbances due to the cornea's inability to properly refract light. Blurred vision can occur as the optic nerve deteriorates over time, affecting visual clarity. Some patients may also experience pain in the eye during acute episodes, particularly in the case of angle-closure glaucoma, where there is a sudden spike in intraocular pressure.

Since all these symptoms—pain in the eye, blurred vision, and seeing halos around lights—can occur in different types or stages of glaucoma, the option that encapsulates all these experiences is the most comprehensive and accurate choice. This collective consideration helps highlight the multifaceted nature of glaucoma and illustrates why a patient may report varying symptoms based on their specific situation with the disease.
