Photophthalmia

Labelled diagram of the structure of the retina

Photophthalmia is inflammation of the eye due to exposure to intense light.

Some sources define photophthalmia as "keratoconjunctivitis caused by ultra-violet light/energy", which obviously has a similar but more specific meaning - i.e. inflammation of the cornea and conjunctiva, rather than the eye in general, and caused by ultra-violet light specifically.


Photophthalmia may be due to the damaging effects of excessive ultra-violet light on the cornea, e.g. as in Snow Blindness. Other possible sources of excessively bright light include ultra-violet lamps and arc welding equipment.
