When someone gets sick or begins to develop a long-term condition, identifying symptoms early is often the key to getting treatment that may cure or slow down the progression. Unfortunately, this quick diagnosis is not always possible.
Whether it is because the signs are too subtle or the symptoms indicate something else, some health issues do not get diagnosed until they have progressed.
Glaucoma is a group of eye diseases where the nerve in the back of the eye gets damaged, eventually causing vision loss and even blindness. In early glaucoma, symptoms may not be straightforward enough to indicate what the problem is.
Structural changes or vision changes can be the first sign, but neither one consistently appears before the other, making it difficult to connect the dots. When the disease advanced even a little, the changes in the eye and the person's vision are easy to identify.
