The Structure/Function Conundrum
- Glaucoma is a neurodegenerative disease causing the loss of retinal ganglion cells
- Ganglion cell numbers range from approximately .7 million to 1.5 million
- Density is greatest in the macula where the ganglion cell layer can be 6 cells deep
- The thinnest and densest layer of ganglion cells is in a 1 to 1.5 mm radius of the fovea

Special Health Alert: Myopia and Glaucoma
Is there a relationship between axial length, myopia, thin corneas and glaucoma? Could that relationship perhaps be a manifestation of the collagen composition of the eye and it’s alteration in these cases. Does a weakened collagen network lend to the development of a “long eye” and a “thin cornea?” Would that logic then transfer to include the integrity of the lamina cribrosa making it more susceptible to pressure perfusion issues? Let’s take a look at glaucoma as it relates to myopia from the perspective of published studies to determine if myopia and axial length increases the risk.
