During the epidemic prevention and control period, in order to prevent the breeding of pathogenic microorganisms at home, many citizens will buy protective equipment such as alcohol and disinfectant at home, and some even buy ultraviolet lamps to disinfect themselves.
Ultraviolet disinfection has the advantages of colorless, odorless, and no chemical residue, but if it is used incorrectly, it is very easy to cause great harm to the human body.
Recently, Master Xu, who was unwell and closed his eyes tightly and did not dare to open, moved into the emergency department of the Third People's Hospital of Hangzhou under the support of his family.
Terrified of the family!
When I woke up, my eyes were tingling and I was in tears
At 3 p.m. that day, when master Xu, 56, woke up from a nap, he found that he could not open his eyes at all, "I couldn't see any light, my two eyes were stinging fiercely, and I kept shedding tears."
Master Xu lay on the bed again for a while. But the situation did not improve, not only a headache came from the forehead, but also the whole body was weak,
Considering that he has been suffering from diabetes for many years, his family is very worried about whether Master Xu will have a sudden cerebrovascular accident, so they quickly sent him to the emergency department of the Third People's Hospital of Hangzhou For medical treatment.
After ruling out the possibility of intracranial-related diseases, Master Xu went to the ophthalmology department for further diagnosis and treatment accompanied by his family, and as soon as he entered the consultation room, he couldn't help but ask, "Doctor, I am so much 'uncomfortable', is it really caused by the eyes?" ”
Dr. Lu Yifeng, who was treated by the Department of Ophthalmology, quickly arranged relevant examinations for him, and as a result, he found that Master Xu had diffuse punctate punctate detachment of the corneal epithelium in both eyes, which was the main cause of his binocular symptoms.
"Have you ever been exposed to UV disinfection equipment today?"
"Is this caused by ultraviolet rays?" Our house did disinfect it in the morning! ”
It turned out that because someone in the family had a cold, and considering the current epidemic situation, the family decided to disinfect the indoor air at home.
At about 6 o'clock in the morning, Master Xu, who got up early, turned on the ultraviolet disinfection lamp in the center of the living room, and under the ultraviolet illumination, he was in close contact for about 10 minutes.
Under this "human evidence and physical evidence", Lu Yifeng clearly diagnosed Master Xu for ultraviolet irradiation induced "electro-photophthalmia", immediately gave the ophthalmology corresponding treatment, after a few minutes, his eye symptoms gradually alleviated, both eyes can be opened naturally, obvious pain and photophobia and tears and other symptoms are gone.
Although the whole body is uncomfortable for an hour, he can also move freely as usual, but Lu Yifeng told Master Xu that his corneal epithelium is still in a state of obvious damage and detachment, and he needs to go home and drip eye drops and ointments on time to promote the cornea to repair as soon as possible.

The onset of the disease does not necessarily occur immediately after irradiation,
This eye disease also has an "incubation period"
Lu Yifeng introduced that in fact, patients with electro-optical ophthalmia like Master Xu are not uncommon in the emergency department of ophthalmology, and have recently received many cases in succession.
It is actually an acute inflammation caused by damage to the cornea and conjunctival epithelium of the eye caused by ultraviolet light. In the northern region, it is mostly caused by the ultraviolet rays reflected by the snow reflecting the sun, and in the southern regions such as Zhejiang, it is mostly induced by accidental direct illumination of ultraviolet lamps at work or life.
Generally, a foreign body sensation occurs in both eyes at the same time, and then there is a sharp eye tingling and burning sensation, light intolerance, tearing, eyelid spasm, and even a significant decrease in vision. Examination may reveal red and swollen eyelids, conjunctival congestion and edema, and sticky discharge from the eye.
"But, Dr. Lu, why did I only get this problem in the afternoon when I took ultraviolet rays in the morning?"
In the face of Master Xu's question, Lu Yifeng explained, "This electro-optical ophthalmia actually has an incubation period. The length of the incubation period depends on the dose of irradiated UV radiation and the length of the irradiation time. In general, when the intensity of ultraviolet radiation is higher and the longer the irradiation time, the shorter the corresponding incubation period, according to statistics, the shortest incubation period is only half an hour, and the longest can reach 24 hours. ”
This also makes it difficult for the public to find their own eyes on the spot, so when the eyes suddenly have acute symptoms, they will often be like Master Xu, accompanied by general discomfort and nervousness and anxiety.
"Encounter" ultraviolet lamps in homes or public places,
The following precautions to keep in mind!
Under the epidemic situation, many units or families may choose to use ultraviolet lamps for indoor disinfection, experts from the Third People's Hospital of Hangzhou City remind here:
When citizens use ultraviolet lamps or instruments in their homes, they must do a good job of prevention. Do "turn on the lights and leave people", pay attention to the distance, avoid direct contact and irradiate ultraviolet rays. After using the UV disinfectant lamp, remember to ventilate for 30 minutes before entering the room.
In public places, if you encounter ultraviolet disinfection, you should avoid it in time, and your eyes should not stare at the ultraviolet disinfection lamp, especially to prevent children from straying in.
If you need to work in a temporary ultraviolet environment, or need to go to a plateau, snow and other strong ultraviolet environments, you need to do relevant protection work in advance, such as wearing ultraviolet protective glasses and overalls and protective gloves to ensure that your eyes and skin will not be exposed to ultraviolet rays.
Once in the ultraviolet environment, accidentally occurred electro-optic ophthalmia, please first maintain calm, do not rub the eyes, so as not to cause secondary damage, and then you can first carry out cold compress treatment of the eye, and then visit the doctor in time, under the guidance of the doctor, pain relief, anti-inflammatory and cornea repair and other ophthalmic treatments to prevent secondary infection damage to the eye.
