The aim of our research is to assess and compare the peripapillary retinal nerve fiber layer (pRNFL) thickness diagnostic capability with those of three macular parameters—macular RNFL (mRNFL) thickness, GCL+ (ganglion cell layer with inner plexiform layer thickness), and GCL++ (mRNFL and GCL+) in primary open-angle glaucoma patients with spectral-domain optical coherence tomography (SD-OCT). From this plexus, the axons emerge as the deep petrosal nerve, which then joins the greater petrosal nerve in the vidian canal, en route to the pterygopalatine ganglion.

Somatic sensory fibers from the face collect into three major trunks: the ophthalmic, from the region of the eyes and above; the maxillary, from the region of the lower eyelids and cheeks down to the upper lip, teeth, and gingivae; and the mandibular, from a region that follows the sideburns down along the jaw and that includes the lower lips, teeth, and gingivae. Retinal neuroaxonal loss is associated with progressive regional brain atrophy and disability in multiple sclerosis. The major splanchnic nerves are the greater, lesser, and least (smallest, renal) splanchnic nerves, which carry preganglionic sympathetic axons from ganglia 6–10 of the thoracic sympathetic trunk to the prevertebral ganglia (celiac, superior mesenteric, and aorticorenal ganglia) in the abdomen.
