As worldwide populations become older because of shifts in demography, PXF may become a matter of greater concern. The search for genes responsible for PXF may lead to the identification of key molecules in pathways critical to the normal functioning of the eye. A better understanding of normal eye function may in turn lead to more accurate diagnosis and prognosis of ocular development, and inevitably to the emergence of novel classifications based on knowledge of the molecular pathology. Such knowledge may lead to more rational disease classification, better diagnostic tests, and improved prognostic accuracy. This is of particular relevance to PXF since there is a shortage of early reliable diagnostic tests and much evidence that the early commencement of treatment can arrest progressive asymptomatic loss of vision due to PXF-related glaucoma. The search for genes responsible for PACG may lead to the identification of key molecules in pathways critical to the normal development of the eye. A better understanding of eye development may in turn lead to more accurate diagnosis and prognosis of ocular development, and inevitably to the emergence of novel classifications based on knowledge of the molecular pathology. Such knowledge may lead to more rational disease classification, better diagnostic tests, and improved prognostic accuracy. This is of particular relevance to glaucoma since there is a shortage of early reliable diagnostic tests and much evidence that the early commencement of treatment can arrest progressive asymptomatic loss of vision for which the disease is renowned. Identification of responsible genes for POAG development can on one hand broaden our knowledge on disease pathophysiology and on the other hand open new doors in the search for pharmacological disease modification. Especially the latter is urgently needed as IOP has for many years been the only pharmacological target and fails to prevent disease progression in a certain proportion of POAG patients.
