Ocular hypertension often develops silently within the eye, imperiling future vision without notable symptoms. Pressures inside the eye gradually climb higher than normal rates as aqueous humour production and drainage fall out of balance. This fluid continually cycles within a healthy eye through balanced inflows and outflows, maintaining appropriate pressure. Yet in cases of ocular hypertension, drainage proves less effective over time, allowing accumulation that squeezes the optic nerve. While pressure builds without obvious effects at first, damage risks developing if left unchecked.
