Premacular membrane formation after scleral buckling for primary rhegmatogenous retinal detachment: prospective study and pathophysiological insights.

The incidence of postoperative PMM formation after RRD repair with SB alone was high. In retinal detachments involving the macular region PMM were more severe, tending to anatomical progression and functional deterioration. Activation of foveal Müller cell in detachments involving the macula may be a key factor in PMM progression.
