kollatähni

Kollatähni is an Estonian term that translates to "macula" in English. The macula is a small, highly sensitive area of the retina responsible for sharp, central vision. This central vision is crucial for detailed tasks such as reading, driving, and recognizing faces. Within the macula, at its very center, is the fovea, which is packed with photoreceptor cells called cones, further enhancing visual acuity.

The macula's function is vital for our ability to perceive the world in detail. Diseases or conditions affecting the macula can have a significant impact on a person's quality of life, often leading to blurred or distorted central vision. Common conditions that affect the macula include age-related macular degeneration (AMD), diabetic retinopathy, and macular holes. AMD, in particular, is a leading cause of vision loss in older adults.

Early detection and management of macular conditions are important for preserving vision. Regular eye examinations are recommended, especially for individuals over the age of 50 or those with a family history of eye disease. Treatments vary depending on the specific condition and may include medications, laser therapy, or surgical interventions. While some macular diseases can lead to irreversible vision loss, others can be managed to slow their progression.
