Age-related changes in and determinants of macular ganglion cell-inner plexiform layer thickness in normal Chinese adults.

Mean mGCIPL thickness showed a small age-related linear decrease with two steep drops in the fifth and seventh decades. Thinner mGCIPL was independently associated with age, thinner pRNFL and higher IOP. These factors should be considered if using mGCIPL to detect progression of glaucoma and other optic neuropathies characterized by the loss of retinal ganglion cells.
