Recently, the topic of “new crown virus is likely to exist eye tendency” rushed to the first microblogging hot search. The reporter interviewed Jinan ophthalmologists learned that eye diseases caused by the new crown infection do exist, including acute macular retinopathy, which used to be a rare disease, but this case has recently appeared in the hospital frequently.

Recently, the topic “new crown virus is likely to exist eye tendency” rushed to the first microblogging hot search. The reporter interviewed Jinan ophthalmologists learned that eye diseases caused by the new crown infection do exist, including acute macular retinopathy, which used to be a rare disease, but this case has recently appeared in the hospital frequently. The public should go to the hospital in time for treatment once eye symptoms such as vision loss and obscuration of vision occur.

A few days ago, 31-year-old Ms. Chen found herself in the “Yang over” after the vision is not very good, see what is blurred, like a mosaic. But she has not linked her vision problems with the new crown infection, thinking that after a few days it will be fine. It wasn’t until it was unbearable that she went to the Eye Hospital of Shandong First Medical University (Shandong Provincial Eye Hospital). In the hospital’s Department of Funduscopic Medicine, doctors found that Ms. Chen had dark reddish-brown lesions in the macula of both eyes, hyperreflective lesions in the outer retina, and broken ellipsoidal and chimeric bands, and was diagnosed with acute macular retinopathy.

How did Ms. Chen, who is young, get the “fundus disease” which is difficult to treat in ophthalmology? The doctor told her that with her medical history, it was determined to be related to a new crown infection. Not only Ms. Chen, the last half month, a single Shandong Provincial Eye Hospital Fundus Internal Medicine Deputy Chief Physician Sun Xiaolei has seen a dozen cases of acute macular retinopathy patients. The disease can be said to be a rare disease, the incidence is not high, Sun Xiaolei in the past four years only saw two cases.

Sun Xiaolei introduced, acute macular retinopathy before the onset of high in the South, because the South more by mosquitoes caused by dengue fever, dengue fever can cause acute macular retinopathy, in the North is less common. However, the disease has recently been seen frequently in patients, and is closely related to the high fever caused by the new crown. “When asked about the medical history, the patients were already infected with neo-crown. However, the disease is not directly caused by the neo-crown virus, it is caused by the damage caused by the immune response of the body caused by neo-crown hyperthermia.”

Sun Xiaolei said the new crown causes changes in the body’s blood vessels and nerves, and it has a certain eye tendency. The virus was known to be secreted in the tear fluid as early as the Wuhan New Crown outbreak. At the same time it caused an immune response that induced neurological and vascular changes, and the autoimmune storm involved the neurovascular. Since the macular region of the eye is functionally important and not well compensated, there are significant functional changes in ocular function as soon as the neurovasculature is attacked.

Previously, the latest research published in Nature Communications showed that the new coronavirus can cause ocular discomfort and retinal inflammation. And a large prospective observational study published in The Lancet also showed that even after vaccination, 24.8%-27.7% of people infected with Neocon can still experience eye soreness.

The study suggests that there is likely to be an ocular tropism for the new coronavirus. In previous animal experiments, a researcher attempted to invade the virus into rhesus monkeys by conjunctival inoculation and induced mild symptoms of new coronavirus infection. In addition, RNA of neo-coronavirus was also detected in the conjunctival swabs of 57% of neo-coronavirus-infected eyes, and the detection rate was higher in those with higher disease severity.

Unlike the severe disease caused by neo-coronavirus, which is mostly in the elderly, acute macular retinopathy complicated by neo-coronavirus mostly strikes young people. Among the dozens of patients recently seen by Sun Xiaolei, most are young people in their 30s, the youngest being 15 years old and the oldest in their 50s, with most of them being women. The reason for this, Sun Xiaolei said, perhaps this is related to the immune characteristics of young people and women. Just as older people don’t get high fever when they are infected with a new crown, younger people have more pronounced symptoms because of their strong immune system and immune stress, and the “intense battle” between the good and the bad in their bodies.

Some of the patients who came to the hospital still had 1.0 vision when they were admitted but had a sense of obscuration, and some had difficulty even counting their fingers. Sun Xiaolei said that 54 percent of patients will have persistent symptoms, such as loss of vision and a sense of obscuration in their vision. Some have no symptoms but are also found to have fundus changes when examined. Upon arrival at the hospital, the doctor will give nerve nutrition, improve circulation, apply hormones for a short period of time, and take vitamin C. The effect of treatment varies from person to person depending on the site of damage, and depends mainly on the individual’s immune response, even if the same drug is used, the final prognosis varies. Those with a good prognosis will recover as before, while some have a self-limiting nature and will get better without treatment, but some patients may progress more strongly.

Previously, Professor Chen Youxin, director of ophthalmology at Peking Union Medical College Hospital, said in an interview with Science and Technology Daily that, at present, the proportion of eye infection symptoms after infection with the new coronavirus Omicron strain is not too high, and the more common eye infection is also conjunctivitis symptoms, mainly manifested as eye dryness, soreness, redness and swelling, tearing, etc., but a very small percentage of people will have acute macular retinopathy, fundus The fundus examination will reveal damage to the macula, especially the outer retina and the ellipsoidal zone, and damage to these areas will cause blurred vision. In addition, when the new coronavirus invades the optic nerve, it can lead to optic neuropathy and impaired vision.

Sun Xiaolei said that in addition to acute macular retinopathy, there are also patients who have New Crown-related keratoconjunctivitis and ocular paralysis strabismus. She reminded the public that once the fever appears blurred vision, do not wait, do not reduce the fever can also go to the hospital for timely consultation, the hospital does not refuse to diagnose positive patients. If they can be seen early, the patient will suffer less damage and have a better prognosis through hormonal regulation of immunity. “Most of the patients we see now come to the hospital only after the fever has subsided and their eyes are still not well, they think that bad eyes in high fever are burned by high fever, the fever has subsided and they are naturally well, such a concept delays the treatment.”
