It is the separation of neurosensory retina from underlying retinal pigment epithelium characterized by the presence of retinal break..

Risk factors:

1. Lattice degeneration
2. Peripheral retinal breaks
3. Pathologic myopia
4. Previous intraocular surgery
5. Trauma
6. Previous retinal detachment
7. Family history

Symptoms :

• Very brief flashes of light (photopsia) in the extreme peripheral (outside of center) part of vision
• A sudden dramatic increase in the number of floaters
• A ring of floaters or hairs just to the temporal side of the central vision
• A dense shadow that starts in the peripheral vision and slowly progresses towards the central vision
• The impression that a veil or curtain was drawn over the field of vision
• Straight lines (scale, edge of the wall, road, etc.) that suddenly appear curved
• Central visual loss

Prevention :

• Avoid direct and indirect injury to the eyes
• Regular eye check up
• If any retinal tears, holes or breaks are identified barrage laser photocoagulation to the breaks to prevent retinal detachment

Treatment :

• Retinal laser photocoagulation and cryopexy
• Scleral buckle surgery
• Pneumatic retinopexy
• Vitrectomy surgery with gas or silicon oil injection
