epiretinaaliseksi

Epiretinaaliseksi refers to a condition affecting the macula, the central part of the retina responsible for sharp, detailed vision. Specifically, it denotes the presence of epiretinal membrane (ERM) formation on the surface of the retina. An ERM is a thin layer of scar tissue that can develop on top of the macula.

This membrane can contract, causing the retina to wrinkle or pucker. This distortion of the macula can lead to visual symptoms such as blurred or distorted vision, a central blind spot (scotoma), or difficulty reading small print. The severity of symptoms depends on the extent of the membrane's contraction and its impact on the retinal tissue.

The exact cause of epiretinal membrane formation is not always clear, but it is often associated with aging. Other contributing factors can include inflammation within the eye, trauma, retinal tears, or complications from eye surgery. In some cases, the condition may develop without any identifiable underlying cause.

Diagnosis typically involves a comprehensive eye examination by an ophthalmologist, including a review of the patient's medical history and visual acuity testing. Optical coherence tomography (OCT) is a key diagnostic tool that provides detailed cross-sectional images of the retina, allowing for the visualization and assessment of the epiretinal membrane. Treatment is generally considered only if the visual impairment is significant. Options may include observation for mild cases or surgical removal of the membrane, known as vitrectomy, for more severe symptoms.
