Retinal detachment occurs when the neurosensory retina separates from the underlying retinal pigment epithelium. This disrupts its blood supply and can lead to permanent sight loss if not treated promptly.
Types and Symptoms
The most common form, rhegmatogenous detachment, is caused by one or more retinal tears that allow fluid to track underneath. Symptoms include flashes, a shower of floaters, and a shadow or curtain across part of the vision.
- May start in the periphery and progress towards the centre
- Can affect one or both eyes, especially in high myopia
- Often associated with recent PVD or trauma
Treatment
Retinal detachment is treated with surgery such as vitrectomy, scleral buckle, or pneumoretinopexy, depending on the pattern. Timing of surgery is critical, particularly when the macula is still attached.
