The structure and function of the macula in patients with advanced retinitis pigmentosa.

RESULTS. The thickness of the ONL in the central macular region was significantly less in the NCRF eyes compared with that in both DRF eyes and controls. The ONL was significantly thinner in the pericentral region in both patient groups compared with that in controls, whereas the thickness of the GCLIPL and INLOPL was significantly decreased only in the NCRF eyes. The RNFL in the peripheral region was significantly thicker, whereas the thickness of the GCLIPL and ONL was significantly thinner in both patient groups compared with that in controls.
