Heroin abuse. Ophthalmoscope view of the retina of the eye of a patient that has been damaged by chronic use of the drug heroin. The macula,where most of the eye's light sensitive cells occur is seen dark-coloured at centre (with a red line pointing to it). The optic disc where nerves and blood vessel enter the eye is yellow at far right. Blood vessels are red. A small yellow patch at upper right of the macula is an area of light- sensitive cells which have been damaged by the heroin abuse. This kind of degeneration is called retinal maculopathy and can lead to damaged vision or blindness | |
