The combination of traction on the retina and of intraocular currents in the presence of a retinal hole is the cause of rhegmatogenous retinal detachment. The strong suction forces of the pigment epithelium and choroid counteract such a development. Chorioretinal scars serve as a seal against currents. Eliminating the effects of traction and of intraocular currents and making use of the absorption forces of the pigment epithelium and choroid are the primary aims in successfully treating rhegmatogenous retinal detachment. Direct closure of the retinal hole is not always necessary.
