glaukomhemfält

Glaukomhemfält refers to a specific pattern of vision loss associated with glaucoma. Glaucoma is a group of eye diseases that damage the optic nerve, which is essential for good vision. This damage is often caused by abnormally high pressure inside the eye. The optic nerve connects the eye to the brain, transmitting visual information.

As glaucoma progresses, it typically affects the peripheral vision first. Glaukomhemfält specifically describes a reduction in the visual field, often starting with blind spots or areas of darkness in the side or upper/lower parts of the visual field. These areas can gradually expand and merge over time, potentially leading to tunnel vision if left untreated. The term "hemfält" translates to "half-field," suggesting that significant portions of the visual field, particularly on one side of the central vision, can be lost. This type of vision loss is usually gradual and painless, meaning individuals may not notice it until it has significantly impacted their sight. Regular eye examinations are crucial for early detection and management of glaucoma and its associated hemifield defects. Treatment aims to lower eye pressure to prevent further optic nerve damage and preserve remaining vision.
