Retinal detachment is a serious eye condition that occurs when the retina, the light-sensitive tissue at the back of the eye, separates from the underlying supporting tissue. This detachment can lead to vision loss if not treated in time. Symptoms typically include sudden flashes of light, floating particles, and a shadow or curtain effect in the field of vision. Common causes include trauma, age-related changes, or holes or tears in the retina. Treatment typically involves surgery to reattach the retina and restore vision, emphasizing the importance of early diagnosis and intervention.
