Push the cotton swab downward to help turn the upper conjunctival sac “inside out”. https://aneskey.com/foreign-body-conjunctival/ Foreign Body https://emedicine.medscape.com/article/1844102-overview#a3 https://www.stjohnvic.com.au/news/eye-injury-first-aid-tips/ Corneal Erosion ̶ FA: ̶ SSS ABC ̶ reassure the casualty ̶ dressing over the injuried eye ̶ seek medical help https://www.atlasophthalmology.net/photo.jsf?node=7384&locale=en Penetrating body FA: ̶ SSS ABC ̶ reassure the casualty ̶ dressing over the injuried eye ̶ Do NOT apply pressure! ̶ seek medical help https://emedicine.medscape.com/article/1844102-overview Burn Chemical injuries ̶ acid/alcali ̶ solvents ̶ Signs: ̶ pain ̶ swelling ̶ red and watery ̶ more sensitive to light ̶ FA in seconds! https://www.denios.cz/ Burns Chemical injuries ̶ FA in seconds: ̶ SSS ABC ̶ open eyelids carefully ̶ wash eye with cold water for 20 minutes ̶ EMS ̶ Do not contaminate healthy eye! https://www.stjohnvic.com.au/news/eye-injury-first-aid-tips/ Chemical injuries ̶ superficial injury of the cornea Acid https://onlinelibrary.wiley.com/doi/full/10.1034/j.1600-0420.2002.800102.x?sid=nlm%3Apubmed Chemical injuries ̶ deeper injury of the cornea ̶ watery conjunctiva with redness Alcali https://www.atlasophthalmology.net/photo.jsf?node=2779&locale=en Physical injuries ̶ Arc welding without protection ̶ Signs: ̶ pain ̶ swelling of the eyelid ̶ blepharospasmus ̶ congested conjunctiva ̶ FA: ̶ Position eye pad / soft clean dressing over injured eye ̶ seek medical aid UV Light Burn, Snow Blindess https://www.goggles4u.co.uk/what-ultra-violet-damage-actually-does-to-your-eyes Blunt eye / orbit injury eye / orbital impact ̶ fractures ̶ lens shift ̶ anterior chamber hemorrhage ̶ retinal injury https://aneskey.com/facial-trauma/ Blunt eye / orbit injury symptoms: ̶ pain ̶ hematoma ̶ visual impairment FA: ̶ SSS ABC ̶ provide medical treatment https://www.drchristopherzoumalan.com/es/photo-gallery/orbital-trauma-orbital-fracture-repair/ Prevention of eye injuries ̶ 90% of injuries are preventable ̶ 70% of injuries are caused by fast-flying debris Use glasses! https://corkeyeclinic.ie/Eye-Injuries Summary ̶ Eye injuries can be prevented. ̶ Acids and alkalis are diluted in the eye and on the skin only with water. ̶ Rinsing is performed with water lying down, for a long time even during transport. ̶ Sterile dressing is applied to the affected eye. ̶ In the case of a perforating eye injury, both eyes are immobilized by applying a bandage after informing the injured person. Learning outcomes ̶ Student can describe the principles of first aid for penetrating eye injuries. ̶ Student describes the basics of first aid in case of acid or lye contact with the eye. ̶ Student is able to list the basic precaution for the prevention of eye injuries.
