3. Summarize electric ophthalmia as the name of the disease. Also known as ultraviolet ophthalmia [1]. It refers to an eye disease characterized by harsh eyes, burning eyes, photophobia and tears, severe pain and black eyes after ultraviolet irradiation [2]. It is an inflammatory reaction of conjunctiva and cornea [1]. It is more common in electric welding and gas welding, and it is damaged by ultraviolet rays generated by light arc and molten metal or improper use of ultraviolet germicidal lamp. Snow blindness is caused by ultraviolet rays that strongly reflect sunlight, such as glaciers, snow, oceans and deserts. It usually happens 6-8 hours after the injury, and the light person only has the feeling of sand in his eyes. The heavier ones have stinging eyes and tears in shame. The serious kind, the eyelids are swollen and hard to open, the eyes are burning with severe pain, the tears are like soup, and the vision is blurred. If there is a rainbow around the lamp, it will recover in more than 2-3 days, and the vision will not be damaged. Occasionally it lasts for a long time, resulting in black eyes.

4 Classification of diseases Ophthalmology

The cause of the disease is long-term work in ice and snow, desert, salt field and vast water surface, walking without protective glasses, or strong ultraviolet radiation such as the sun and ultraviolet lamps.

When welding or gas welding, there is no protective equipment, but it is damaged by ultraviolet rays generated by light arc and molten metal, or the ultraviolet germicidal lamp is improperly used.

Glaciers, snow, sea, desert, etc. Strong reflection of sunlight.

Pathophysiology Acute inflammation caused by absorption of a large amount of intense ultraviolet rays by corneal epithelial cells and conjunctiva.

7 Symptoms and signs Electro-optic ophthalmia usually has a incubation period of 6-8 hours. The patient's eyes suddenly felt burning sensation and severe pain, accompanied by photophobia, tears, eye spasm, headache, eyelid and facial skin flushing and burning sensation, and conjunctival congestion and edema.

Gentle people only have a harsh feeling in their eyes; Serious people have itchy eyes, pain, shame and tears; In severe cases, the eyelids are swollen and difficult to open, the pain in the eyes is like fire, the tears are like soup, and the vision is blurred. If there is a rainbow around the lamp, they will recover in more than 2 ~ 3 days, and their eyesight will not be damaged. Occasionally, it will not heal for a long time, resulting in black eyes.

8 Diagnosis, examination and diagnosis points of electro-optic ophthalmia: ① There is a history of ultraviolet irradiation or walking in snow and desert, and the incubation period is as short as 30 minutes and as long as 24 hours, usually 3 ~ 12 hours. ② Sudden attack, with foreign body sensation and tingling sensation in both eyes at first, followed by severe pain, photophobia, tears, blepharospasm, ciliary neuralgia, headache, blinking and decreased vision. ③ Examination showed erythema and swelling of eyelid in different degrees, slight congestion of eyelid conjunctiva, mixed congestion and edema of bulbar conjunctiva and corneal opacity. ④ After fluorescein staining, slit lamp examination showed special performance [1].

1. Ask about the injury history in detail, including the cause of injury, the type, direction, speed, distance and time of injury. Distinguish between mechanical damage and non-mechanical damage. If it is mechanical injury, further distinguish eyeball contusion, eyeball penetrating injury or accessory injury, and whether there is foreign body in eyeball or orbit and eyelid. If it is non-mechanical, it should be divided into physical and chemical.

2, must pay attention to the general situation, such as shock, craniocerebral trauma, infection, etc. Those complicated with systemic trauma should ask the relevant departments for diagnosis and treatment. The local examination must be light, do not press the eyeball, and drop local anesthetic when necessary. If combined with craniocerebral trauma, don't mydriasis without nervous system examination.

3. When examining foreign bodies on the eyeball surface, special attention should be paid to cornea, inferior tarsal sulcus and fornix conjunctiva.

4. For patients with ocular contusion, the ocular adnexa and the anterior and posterior parts of eyeball should be examined in detail. For patients with penetrating eyeball injury, the size, location and depth of the wound should be carefully investigated, and whether there is eyeball content protrusion, eye movement disorder or foreign body retention, and drawings should be drawn when necessary. The scope and degree of thermal and chemical burns should be described. Pay attention to whether there is phosphorus odor on the wound surface when phosphorus burns, and check whether there is phosphorescence in the dark.

5, check the vision and function of each eye, in addition to the obvious eye penetrating injury, should check the fundus as much as possible, mydriasis inspection when necessary.

6. Anyone suspected of orbital fracture or intraocular foreign body should be examined by X-ray photography, CT or ultrasound. When foreign bodies are found, they should be located.

7. Pay attention to the health of eye vision, the situation of various parts before and after the eyeball, and whether there is sympathetic ophthalmia.

8, eye trauma should be treated as an emergency. For chemical eye injury, rinse with clear water immediately, and then check it in detail. If the wound is polluted or deep, appropriate antibiotics and tetanus antitoxin should be used.

The treatment plan was 1, and 0.5% dicaine eye ointment or human milk was applied.

2. Drop antibiotic solution or apply antibiotic eye ointment to prevent infection. Corticosteroid eye drops can also be added as appropriate.

3, cold compress eyes to reduce congestion, reduce * * *.

4. Wear colored glasses when necessary.

5, Chinese medicine treatment:

Take the points of Shuanghegu, Taiyang and Fengchi. Leave the needle 10 ~ 15 minutes, and strengthen it in the middle *** 1 time. [ 1]

Acupuncture at bilateral Hegu, Neiguan, Jingming and Fengchi points (or injection of procaine) can relieve * * *.

It can also be relieved by soaking Rhizoma Coptidis in human milk and clearing eyes with fresh milk or fresh eggs. In severe cases, traditional Chinese medicines such as Eye Sweet Dew Drink and Qufeng Cooling Drink can be selected.

The patient's diet should be light, spicy and * * * food should not be eaten.

10 emergency measures After the occurrence of electro-optic ophthalmia, a simple emergency measure is to use boiled and cooled human milk or fresh milk to relieve pain. The method of use is to order it once in the first few minutes, and then with the relief of symptoms, the time for ordering human milk or milk can be appropriately extended. You can also soak your eyes in cold water with a towel and close your eyes to rest. After emergency treatment, in addition to rest, we should also pay attention to reducing light and eye movement and friction as much as possible.
