Fluctuating eye pressure associated with visual field deterioration in glaucoma patients
...es abound about the mechanisms of retinal ganglion cell
damage in glaucoma, but no single cellular or molecular cause satisfactorily explains the condition in all patients, Dr. Caprioli writes. Long-term variability may disrupt homeostatic mechanisms. Irregular and large IOP fluctuations may cause a loadi...
