Optic nerve head: A diagnostic Saga!

Optic nerve head assessment can be a window to diagnosing a plethora of diseases. It can provide us with a hint into glaucoma as well as many non glaucomatous optic neuropathies associated with neurological conditions like space occupying lesion, raised intracranial tension, demyelination, & systemic diseases like uncontrolled hypertension, diabetes, vascular auto- dysregulation, as well as toxic dietary influences & deficiencies, which can have serious consequences in terms of not just a threat to vision, but also systemic morbidity & mortality.
