Rhegmatogenous retinal detachment is separation of the neurosensory retina from the underlying retinal pigment epithelium characterized by the presence of a retinal break in concert with vitreoretinal traction that allows accumulation of liquefied vitreous under the retina.
Risk factors include the following:
Fresh Retinal Detachment
Long standing retinal detachment characterised by proliferative vitreo retinopathy changes
Rhegmatogenous detachment is treated with one or more methods, depending on the cause and location of the lesion. These methods involve sealing the retinal breaks by laser or cryotherapy. In scleral buckling, a piece of silicone is placed on the sclera, which indents the sclera and pushes the retina inward, thereby relieving vitreous traction on the retina. During this procedure, fluid may be drained from the subretinal space. The other modalities of treatment include pneumatic retinopexy (which means attachment of retina using gas) and vitrectomy. Laser photocoagulation using green Argon, red Krypton or Diode laser or cryopexy ( scarring the retinal tear by freezing) can help in treating retinal breaks. Surgical treatment is successful in most of the cases of rhegmatogenous retinal detachments.
Rhegmatogenous detachments due to vitreoretinal traction may be treated by vitrectomy. Vitrectomy is an increasingly used treatment for retinal detachment. It involves the removal of the vitreous gel and is usually combined with filling the eye with either a gas bubble (SF6 or C3F8 gas) or silicone oil. Vitrectomy is followed by filling of the vitreous cavity with gas (SF6. C3F8 gas) or silicone oil (PDMS). The disadvantage of silicone oil is that it causes a myopic shift and it needs to be removed by 6 months whereas when using gas, it warrants proper patient positioning after surgery and gas gets absorbed in a few weeks and there is no myopic shift.

Yes, even a slight blockage of the vision caused by partial retinal detachment can result in blindness if not treated right away.
No. There is no medicine, eye drop, vitamin, herb, or diet that is beneficial to patients with retinal detachment.
Detachment is more likely to occur if the other eye has the condition (such as lattice degeneration) associated with retinal detachment in the first eye. If only one eye suffers a serious injury or requires eye surgery then, of course, the chance of detachment in the other eye is not increased by the event.
The outlook depends on the severity of the condition and how quickly you get expert medical care. Some people will recover completely, especially if the macula isn’t damaged. The macula is the part of the eye responsible for clear vision and is located near the center of the retina. However, some people may not regain full vision. This can occur if the macula is damaged and treatment isn’t sought quickly enough.
