What is viral keratitis? The cornea is the clear part of the front of the eye, commonly referred to as the black eye. Bacteria, viruses, allergies, trauma, etc. can cause inflammation of the black eye, which is known as “keratitis”. Viral keratitis is caused by viral attack – a common virus called simple rash virus, once it enters the body, usually most of the nerve tissue in the human body latent down, there is no manifestation of the disease. However, when a child’s resistance decreases due to fever, exertion, trauma or other reasons, the virus will be “activated” and multiply in the body’s cells and released into the corneal tissue, causing viral keratitis. Symptoms of viral keratitis Viral keratitis is often preceded by a history of flu or fever, corneal abrasions, local and systemic hormone use, or exertion. Initially, the corneal epithelium is cloudy with small dots, mild ciliary congestion, photophobia and foreign body sensation. This is followed by the formation of small blisters, which quickly rupture and interconnect, forming dendritic shallow ulcers (clinical diagnosis of dendritic keratitis). Pain, photophobia, lacrimation, and blepharospasm symptoms increase. Corneal perception is diminished. If the ulcer does not progress to the periphery and deeper layers, it can heal over a few days to weeks, leaving a small scar of cloudiness that has little effect on vision. In dendritic individuals who have been untreated for a long time or who have used hormones, the lesion develops deeper into a map-like form (map keratitis), and the symptoms worsen again, often secondary to iridocyclitis, but usually without anterior chamber pus accumulation, suggesting the possibility of a mixed bacterial infection. The inflammation subsides and the ulcer heals, mostly leaving a degree of scarring and neovascularization that endangers vision. The first thing you need to do is to take a look at the actual product. 2, avoid alcohol: alcohol can reduce the body’s immunity, so that the virus to accelerate the rate of reproduction, therefore, viral keratitis patients must give up alcohol and alcoholic beverages. 3, avoid lamb: because of viral keratitis patients with deep corneal lesions, is the performance of the immune response, and eating lamb can aggravate this immune response, leading to aggravation, so, viral keratitis patients do not eat lamb. 4, avoid hot compress eyes: because the human cornea most of the time every day (except sleep) are in a cooler environment, have been used to. If in its illness, suddenly apply a higher temperature to its disposal, it is like pouring oil on the fire, so that it suffers the ravages of high temperature, lack of oxygen. 5, avoid cutting corners with medication: antiviral drops eye drops a day to ensure that the number of times 6 to 8 times, can not be reduced. The reasoning is simple, the use of drugs such as soldiers, which is like fighting a war, conquering a city would have required 100,000 elite soldiers, if only 50,000 troops, the results can be imagined. 6, avoid wrapping the eyes: wrapping the eyes can make the conjunctival sac temperature rise, increased secretions, conducive to bacterial, viral reproduction, and the gauze used may also scratch the cornea. 7, avoid closing the eyes and head down: this action may cause the patient eye bruising, aggravating the disease. 8, avoid stopping the hormone: some patients treated with hormones, when the condition is rapidly controlled, the cornea to restore the transparency, vision improvement is more satisfactory, it is mistaken that their disease has been cured, take the initiative to stop the drug, resulting in serious consequences. They do not understand that hormone usage is special and needs to be stopped in a decreasing manner. 9, avoid a path to run to black: patients in the use of a certain antiviral drugs, such as inhibitory antiviral effect is not satisfactory, can be replaced with other types of antiviral drugs, such as killing antiviral drugs under the guidance of doctors. The actual fact is that you can get a lot more than just a few of these. The most common types of viral keratitis are herpes simplex keratitis, cowpox keratitis, and herpes zoster keratitis. For herpes simplex viral keratitis, serologically positive adults and children are the main source of transmission, and the virus can be present in tears, saliva, and breath.
