Definition
According to Oxford's Dictionary of Biomedicine, visual defects arise from the following: problems with the optics of the eye or with the transparency of the cornea, progressive loss of retinal cells, retinal detachment, and/or infection. Blindness can also be a feature of more complex syndromes and can result from damage to relevant parts of the brain.[1] The adnexa of eye refers to accessory visual structures, such as the eyelid and the lacrymal gland.
