Tosi GM, et al. - Researchers performed this prospective study to evaluate corneal subbasal nerve density (SBND) and corneal sensitivity (CS) following pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) without intraoperative 360-degree laser treatment using contact or noncontact panoramic viewing systems. Findings demonstrated a greater SBND reduction after PPV with a contact viewing system vs a noncontact system. Multivariate analysis revealed no significant influence for cataract surgery related to PPV, pseudophakia, surgical time, intraocular pressure, or for laser in horizontal sectors for PPV groups. High correlation was observed between SBND and CS.
