Etiology. Burns to the eyes radiant energy, rich in ultraviolet rays, were observed when welding filming in high-altitude locations (snow blindness).

The pathogenesis. Burns of the conjunctiva and cornea. When a particularly intense burn when light is fixed very high light intensity, there may be a lesion of the macula. Gridshells in these cases, it appears in the macular region is totally destroyed, burnt (perforated pigmentosa).

Symptoms and course OPHTHALMIA ELECTRIC (LIGHTING) (INFECTIONS ELECTRICA)

Symptoms. Sharp, acute eye pain, sudden onset a few hours after the burn. Conjunctival hyperemia without detachable. Severe tearing and blepharospasm. In severe cases, in addition to konyunktivalny, also pericorneal injection. Rogovin seems opaque, devoid of gloss. Pupils are tight, with sluggish reaction to light.

The course is usually very sharp; sharp pains extend no more than one day and within a few hours rest. With the defeat of the cornea for longer, resistant. In the case of the formation of a perforated retinitis. vision loss can't be recovered.

Recognition OPHTHALMIA ELECTRIC (LIGHTING) (INFECTIONS ELECTRICA)

Recognition is not difficult on the basis of history and clinical picture (acute irritation without discharge).

Prevention OPHTHALMIA ELECTRIC (LIGHTING) (INFECTIONS ELECTRICA)

Prevention is crucial. Proper use of protective shields and welding helmets. During filming - protective lamp guards. The compulsory wearing blue or smoked glasses when mountain climbing and polar travel. Compliance with great caution when observing a solar Eclipse (the most frequent causes of a perforated pigmentosa); in this case it is necessary to use black (smoked) glass.

Treatment of OPHTHALMIA ELECTRIC (LIGHTING) (INFECTIONS ELECTRICA)

For acute pain cold lotions sleeps with tea or a solution of tannin for ever; puscarie drops quinine. Vaseline oil. Astringents (zinc, tannin with boric acid). The eye drops.
