Stage 4 is defined by subtotal retinal detachment. The retinal detachments are generally
concave and most are circumferentially oriented. Retinal detachments usually begin
at the point of fibrovascular attachment to the vascularized retina and the extent
of detachment depends on the amount of neovascularization present. Stage 4A is defined
by retinal detachment which spares the macula. Stage 4B is defined by retinal detachment
involving the macula.;
