Abstract: The majority of our daily activities and routines are highly dependent on vision. What we experience as our vision arises from the detection and encoding of visual signals in the retina, which are then interpreted in the brain. This interpretation has the benefit of providing a level of constancy to what we experience as vision but also limits our ability to perceive subtle decline in our own vision. This underlies a challenge in the early diagnosis and treatment of sight threatening diseases such as glaucoma. Glaucoma is characterized by the progressive dysfunction and death of retinal ganglion cells (RGCs), the neurons that relay visual information from the retina to the brain via their axons, which bundle to form the optic nerve. To be diagnosed with glaucoma requires a degree of RGC loss sufficient to produce perceptual changes to vision. In the majority of cases, the continued progressive loss of vision is gradual but there are subtypes, which more rapidly reach blindness. Consequently, up to 40% of treated patients will reach blindness in at least one eye in their lifetime (Peters et al., 2014). Given that current estimates place the number of people with glaucoma at over 100 million globally (Tham et al., 2014), glaucoma is a major health concern. The main risk factors for glaucoma are age, genetics, and high intraocular pressure (IOP). IOP lowering is the only proven glaucoma treatment; however, a large percentage of patients do not respond to IOP lowering (i.e., IOP remains high despite treatment), continue to lose vision despite IOP control (i.e., reducing IOP does not prevent progression), or are normotensive (develop glaucoma despite having IOPs in the normal range). There is, therefore, a large clinical need for neuroprotective therapies for glaucoma that act independently of IOP (Tribble et al., 2023).
