		Photokeratitis definition - Medical Dictionary definitions of popular medical terms easily defined on MedTerms
		Photokeratitis: A burn of the cornea (the clear front surface of the eye) by ultraviolet B rays (UVB).
		The condition typically occurs at high altitudes on highly reflective snow fields or, less often, with a solar eclipse.

		Photokeratitis doses at 270, 280, and 290 inn led to a superficial corneal damage.
		UVR exposure at photokeratitis doses at 310 inn resulted in severe corneal damage, where apoptosis was seen in the epithelium, the keratocytes through the whole corneal stromal thickness, and the endothelium.
		Repeated exposures of the corneas to photokeratitis doses at 310 nm at 1 week intervals resulted in hyaluronan deposits in the corneal stroma, and reduction of the keratocyte apoptosis level.

	WHO \| The known health effects of UV
		Photokeratitis is an inflammation of the cornea, while photoconjunctivitis refers to an inflammation of the conjunctiva, the membrane that lines the inside of the eyelids and eye socket.
		These inflammatory reactions may be compared to a sunburn of the very sensitive skin-like tissues of the eyeball and eyelids and usually appear within a few hours of exposure.
		Photokeratitis and photoconjunctivitis can be very painful, however, they are reversible and do not seem to result in any long-term damage to the eye or vision.

		Ultraviolet radiation may cause photokeratitis, a painful inflammation of the cornea of the eye.
		The spectral responsivity for photokeratitis - the action spectrum - follows a characteristic curve, the maximum of which lies at 288 nm according to Coga and Kinsey, at 270 nm according to Pitts et al.
		The opinion expressed by several authors, that the same action spectrum should exist for photoconjunctivitis and photokeratitis, cannot be shared by CIE Division 6, since the cornea and the conjunctiva of the human eye are different from both anatomical and histological standpoints.

	Prevent Disease.com - Winter Sun's Rays Can Still Be Damaging
		Photokeratitis, a condition comparable to sunburn, is a particular danger for sun-exposed eyes.
		Photokeratitis occurs when the sensitive tissues of the eyeball receive too much ultraviolet light.
		Although the condition usually heals with few complications over time, photokeratitis can be painful and repeated bouts may have lasting effects on vision.

		Photokeratitis and conjunctivitis appear together and are known as ÔKerato Ð conjunctivitisÕ, or more commonly known as; Welders Flash, Arc Eye and Snow Blindness.
		The symptoms are severe irritation, with a sensation of grit in the eye, copious watering (lacrimation), aversation to bright light (photophobia), and spasm of the lid muscles (plepharospasm).
		Photokeratitis has a latency period which may vary between 0.5 and 24 hours, but is commonly between 6 and 12 hours.

	UV Protection
		Two types of UV radiation, UV-A and UV-B, are able to penetrate the ozone layer to reach the earth’s surface.
		Extensive exposure of the eyes to UV radiation over a short period of time may result in photokeratitis, a “sunburn of the eye,” which has symptoms that include red eyes, a sensation of dust in the eyes, an extreme sensitivity to light and excessive tearing.
		Photokeratitis is most common in situations where unprotected eyes are exposed to highly reflected light, such as light reflected off of snow- or sand-covered terrain or large bodies of water, and for people whose eyes are frequently exposed in tanning booths or in close proximity to welding.

		Environmental UVB in concert with cold wind and snow microcrystals has the potential to cause photokeratitis (snow blindness), a rare but painful temporary disorder of the cornea.
		Photokeratitis generally corrects itself within 12 to 48 hours.
		It is generally agreed that there are many factors that might be associated with cataracts, a gradual clouding of the lens of the eye.

		However, if the tetanizing weapon were directed at the eyes for several minutes the target subject would experience actinic conjunctivitis and photokeratitis.
		Conjunctivitis is the inflammation of the conjunctiva, which is the membrane that covers the anterior surface of the eye and the eyelid.
		Photokeratitis is a painful irritation of the cornea that is accompanied by a sensation of foreign matter in the eye, minor swelling, lacrimation and photophobia.

	Welcome to Eye Pro
		A common symptom of damage from tanning without eyewear is photokeratitis, often called “corneal burn”, “welder’s flash” and “snow blindness”.
		Photokeratitis usually lasts only 2-3 days, but you’ll want the anesthetic eye drops the doctor can give you for the pain, and they will check your eyes to see if you also need anti-biotic drops for any infection picked up with the corneal burn.
		It sounds like you are using a stand-up unit, and if that’s the case, you might find disposable eye protection is the best, as you won’t have strap lines (they stay on with adhesive).

		To present a case series of photokeratitis secondary to exposure to UV light emitted by lamps used in water purification systems for fish tanks.
		All patients were seen by a single observer during casualty sessions at The Birmingham and Midland Eye Centre between July and December 2002.
		Although UV light has been reported to cause photokeratitis, cases due to UV light from fish tank water purification systems have not been previously reported.
