Description of Age-Related Eye Conditions: Neuro-Ophthalmic Causes of Vision Loss Lecture
This lecture defines neural-ophthalmic study and how neuro-ophthalmologists decide if vision loss is due to a neural cause. Determinations are made regarding if the vision loss is unilateral or bilateral (meaning one or both eyes) and if vision loss occurred suddenly or over a period of time. These facts help the physician determine if the cause is inflammatory, toxic or metabolic or compression of the optic nerve. The types of tests used by the physician are described such as visual field tests, a slit-lamp microscope to examine structures in around the eye and Optical Coherence Tomography (OCT) to determine cell thickness layers & identify clues of pathobiology.
