What causes eye inflammation

Eye inflammation can still cause great harm to your body, and there is no cause at all. Therefore, you need to go to the hospital for further examination to confirm the cause of your illness and do targeted treatment based on the cause of your illness. In this way, the effect will be better. In addition, you must also be careful not to irritate your eyes.

Any factor that can cause tissue damage can be a cause of inflammation, namely an inflammatory agent. They can be grouped into the following categories:

(I) Biological factors

Bacteria, viruses, rickettsia, mycoplasma, fungi, spirochetes and parasites are the most common causes of inflammation. Inflammation caused by biological pathogens is also called infection. Exotoxins and endotoxins produced by bacteria can directly damage tissues; viruses replicate in infected cells, causing cell necrosis; certain antigenic pathogens damage tissues by inducing immune responses after infection, such as parasitic infections and tuberculosis.

(II) Physical factors

High temperature, low temperature, radioactive substances, ultraviolet rays, and mechanical damage.

(III) Chemical factors

Exogenous chemicals such as strong acids, strong alkalis, turpentine, mustard gas, etc. Endogenous toxic substances such as decomposition products of necrotic tissue and metabolic products that accumulate in the body under certain pathological conditions, such as urea.

(IV) Foreign matter

Foreign objects that enter the human body through various pathways, such as various metals, wood debris, dust particles, and surgical sutures, can cause varying degrees of inflammatory responses due to their different antigenicity.

(V) Necrotic tissue

Ischemia or hypoxia can cause tissue necrosis, which is a potential inflammatory factor. The congested hemorrhagic bands and infiltration of inflammatory cells at the edge of fresh infarction are manifestations of inflammation.

(VI) Allergic reaction

When the body's immune response is abnormal, it can cause inappropriate or excessive immune responses, resulting in tissue and cell damage and leading to inflammation. Tissue damage caused by immune response is most common in various types of hypersensitivity reactions: type I allergic reactions such as allergic rhinitis and urticaria, type II allergic reactions such as anti-basement membrane glomerulonephritis, type III allergic reactions such as glomerulonephritis caused by immune complex deposition, type IV allergic reactions such as tuberculosis and typhoid fever; in addition, there are many autoimmune diseases such as lymphocytic thyroiditis and ulcerative colitis.
