Hornhinnebrännskada

Hornhinnebrännskada is a medical condition affecting the cornea, the transparent outer layer of the eye. It occurs when the cornea is damaged by heat or chemical agents. Common causes include exposure to hot liquids, steam, or chemicals like acids or alkalis. Symptoms can vary depending on the severity of the burn but often include pain, redness, blurred vision, tearing, and a sensation of having something in the eye. In severe cases, it can lead to permanent vision loss or scarring of the cornea.

Immediate first aid is crucial. If the burn is caused by a chemical, the eye should be flushed with copious amounts of clean water for at least 15-20 minutes. This is typically done by holding the eyelid open and letting water flow from the inner corner of the eye outwards. If the burn is from heat, removing the source of heat and then seeking medical attention is advised. Medical treatment depends on the extent and cause of the injury. It may involve antibiotic eye drops to prevent infection, pain relief medication, and sometimes special contact lenses to aid healing and reduce pain. In cases of severe damage, surgical intervention might be necessary to restore vision. Prevention is key, and this includes wearing appropriate eye protection when working with chemicals or in environments with a high risk of heat exposure.
