Sjóntruflana

Sjóntruflana is the Icelandic term for visual disturbances. These can manifest in various ways and affect an individual's perception of sight. Common types of sjóntruflana include floaters, which are small specks or cobweb-like shapes that drift across the field of vision, and flashes, which are perceived as sudden bursts of light. Other forms can involve distorted vision, such as wavy or bent straight lines, or a temporary loss of vision in a specific area.

The causes of sjóntruflana are diverse. Some are benign and occur as a natural part of aging, like the development of posterior vitreous detachment, which often leads to floaters. However, visual disturbances can also be indicative of more serious underlying conditions. These can include retinal detachment, glaucoma, optic neuritis, migraines, or even neurological issues affecting the brain. Certain medications or substances can also trigger temporary visual anomalies.

Diagnosis of sjóntruflana typically involves a comprehensive eye examination by an ophthalmologist. This may include visual acuity tests, examination of the retina and optic nerve, and possibly imaging techniques like optical coherence tomography (OCT) or fluorescein angiography. The treatment approach depends entirely on the identified cause. While some visual disturbances require no intervention, others may necessitate medical treatment, laser therapy, or even surgery to preserve or restore vision. Prompt medical attention is advised if new or worsening visual disturbances are experienced.
