netzhautriss

Netzhautriss, also known as a retinal tear, is a condition where a break occurs in the retina, the light-sensitive tissue lining the back of the eye. This tear can happen when the vitreous humor, the gel-like substance filling the eye, pulls away from the retina and causes a tear. Risk factors for developing a retinal tear include age, nearsightedness, a history of eye injury, and previous eye surgery.

Symptoms of a netzhautriss can vary but often include the sudden appearance of floaters, which are small specks or cobwebs that drift in the field of vision, and flashes of light. A shadow or curtain may also appear in the peripheral vision. If a retinal tear progresses and leads to a retinal detachment, where the retina pulls away from the back of the eye, vision loss can occur.

Diagnosis is typically made through a dilated eye examination by an ophthalmologist. Treatment for a retinal tear depends on its severity and whether it has led to a detachment. Options may include laser surgery to seal the tear or cryopexy, a freezing treatment. In cases of retinal detachment, more extensive surgery may be required to reattach the retina. Prompt medical attention is crucial to prevent permanent vision loss.
