Which condition involves the retina being pulled and detached?

Retinal detachment is the condition where the retina, the light-sensitive layer of tissue at the back of the eye, becomes separated from its underlying supportive tissue. This can occur due to various factors such as trauma, degeneration, or other retinal disorders. When the retina detaches, it is pulled away from its normal position, disrupting the vision and potentially leading to permanent damage if not treated promptly.

Understanding retinal detachment is crucial because it can lead to symptoms like flashes of light, floaters, or a shadow in the peripheral vision. Immediate medical attention is often required to reattach the retina and preserve vision. Other conditions mentioned, such as macular degeneration, astigmatism, and glaucoma, do not involve the physical pulling or detachment of the retina from the underlying tissue. Instead, they represent different ocular issues: macular degeneration primarily affects central vision over time, astigmatism is related to the shape of the cornea affecting clarity, and glaucoma involves increased intraocular pressure that can damage the optic nerve.
