Glaucoma is a sight-threatening, progressive optic neuropathy whose incidence increases with age. Currently, the only proven treatment for glaucoma is the reduction of intraocular pressure (IOP). As medical treatment has become safer and diagnostic modalities have become more sensitive, it has become possible to detect and treat glaucoma earlier. This means that with more aggressive screening and treatment, a common cause of irreversible blindness can be prevented. As more patients are treated earlier, it is important not only for ophthalmologists but also for primary care physicians to be aware of the barriers to adherence and possible interactions and side effects of glaucoma medications. Parallels between glaucoma and other neurodegenerative disease are stimulating new approaches to therapy beyond IOP control, targeted directly at the prevention of axonal loss.
Key words: glaucoma, intraocular pressure, medications, neuroprotection, retinal ganglion cell.
