Beat the eye on the eyelids, and the eyes are red and swollen.
On the morning of September 8th, Mr. Wu, who lives in Fuyong, Shenzhen, felt a bug flying to the position of the lower eyelid of his left eye. He took it and killed it. He rubbed his eyes unconsciously. One hour later, Mr. Wu felt red and swollen in his left eye and pain. He went to the local community health clinic and was diagnosed as acute conjunctivitis. As his eyes continued to be uncomfortable, Wu went to the local hospital for emergency treatment at noon. His left eye vision had dropped to 0.02 and intraocular pressure was 53 mmHg (within 20 mmHg of normal intraocular pressure). The examination found that Mr. Wus left eye conjunctiva was cloudy and edematous. The doctor admitted him to the hospital with acute glaucoma for treatment of intraocular pressure reduction and local anti-inflammatory treatment.
The next day, Mr. Wus left eyelid became more swollen, with spasms and yellowish-green secretions; his cornea was also swollen, with extensive grey-white infiltration; and his anterior chamber was filled with pus. Doctors considered that it might be Pseudomonas aeruginosa infection, diagnosed as bacterial keratitis, and treated Mr. Wu with systemic and local anti-infection.
After anti-infective treatment, Mr. Wu left eye symptoms did not ease, local inflammation continued to develop, so referred to the ophthalmic hospital. When he arrived at the ophthalmology hospital in the afternoon of September 10th, Mr. Wus left eye was swollen until he could not open his eyes. Corneal disease doctor at dawn for its diagnosis and treatment, need to open the eyelids to see the cornea, after examination visual acuity has been lost, only light sense. Dr. dawn was diagnosed as bacterial keratitis and orbital cellulitis and then hospitalized.
Dr. dawn said that the cornea had dissolved and perforated, and the disease had developed into endophthalmitis. Antibiotics were injected into the vitreous cavity of the left eye (intraocular treatment), and antibiotics were given every 15 minutes (extraocular treatment) to control inflammation to the fundus.
Doctor Dawn has invited the director of Ophthalmology Department of the hospital to consult with multi-disciplinary experts many times in order to keep Mr. Wus eyeball. After 1 days of treatment, Mr. Wu felt that his left eye was less stinging and his eyeballs could be turned. But the bacteria were fierce. In September 13th, it had been infected inside the eyeball. Drug therapy was no longer able to control the disease. Bacteria can spread to the brain through the optic nerve, and eventually they can only remove the eyeballs.
Flying insects may be toxic. Citizens should avoid touching their eyes as far as possible.
Mr. Wu is only 36 years old. His mother cried sadly in the hospital because of a small flying insect that caused eyeball removal. No one had thought that a small flying bug would do such a great harm. The Nandu reporter learned that experts suspected that the flying insects killed by Mr. Wu were poisonous and carried very virulent bacteria. They just shot dead under the eyelids. In addition, the patient rubbed his eyes again. The two toxicities overlapped, resulting in a rapid development of the disease. Within 48 hours, the flying insects could break through the surface of the eyes and infect the whole body. Eye.
Experts remind the public that there are many kinds of insects, many of them are toxic, if not carefully contacted, try to avoid touching the eyes; if the eyes occur redness, swelling and pain, should be the first time to see an eye specialist hospital.
The doctor reminding
Be careful of Pseudomonas aeruginosa corneal ulcer
This time Mr Wu unfortunately removed the eyeball, pathological analysis to a week after the results, doctors highly suspected that pseudomonas aeruginosa infection. The doctor introduced that the Pseudomonas aeruginosa corneal ulcer is caused by the Pseudomonas aeruginosa infection, is one kind of serious suppurative keratitis, the symptom is intense, the development is rapid, may destroy the entire cornea in 24 ~ 48 hours, may be blind within a few days.
Pseudomonas aeruginosa is very virulent, but its invasiveness is very weak. It must invade corneal tissue through damaged epithelium to cause infection. Therefore, various forms of corneal trauma, keratitis, corneal malacia, head and face tumor radiation, chemical injury and exposure to keratitis and other factors caused by corneal epithelial unhealthy conditions, can become the cause of infection.
Pseudomonas aeruginosa can produce a protein lysozyme besides its strong toxicity. Collagenase is produced by the ulcer itself. Both protein lysozyme and collagenase have collagen lysis on the corneal lamellae. Collagenase activity depends on the concentration of calcium ions, which is more active at a concentration similar to that of serum calcium, while lacrimal and aqueous humors are constantly supplemented with calcium ions. Thus, more active collagenase results in large and rapid dissolution and necrosis of corneal tissue, resulting in early corneal perforation.
