Inflammation of the eye is often referred to as eye congestion and swelling, resulting in painful eyes with tearing. There are many parts of the eye, including the conjunctiva, cornea, sclera, uvea, and retina, and all of these tissues can become inflamed, called conjunctivitis, keratitis, uveitis, and retinitis, respectively. Inflammation manifests differently in different tissues and affects vision differently. Therefore, if you experience painful eye congestion, you should visit an ophthalmologist to determine what kind of tissue is inflamed. If it is accompanied by vision loss, you should visit an ophthalmologist as soon as possible. Keratitis and uveitis can cause serious damage to vision. Depending on the urgency of the onset, inflammation can be divided into acute, subacute and chronic, and according to the different causes can be divided into infectious and non-infectious, eye inflammation is currently still mainly medication-based. Currently, the treatment of conjunctivitis, keratitis, scleral eye and uveitis is based on eye drops. Among the many eye drops, they can be broadly divided into antibacterial (oxyfloxacin eye drops), antiviral (acyclovir eye drops), antiallergic (sodium cromoglycate eye drops) and antifungal, etc. If the infection is mixed, then multiple drugs need to be used in combination, but they need to be used according to the patient’s own situation For example, if you have allergies, you should avoid using them, and if you have abnormal liver and kidney functions, some drugs cannot be used, so you need professional medical guidance to use them.
