Which of the following is a common cause of retinal inflammation?

Retinal inflammation can often be attributed to systemic diseases. Conditions such as autoimmune disorders, infectious diseases, and metabolic disorders can lead to inflammatory processes in the retina. These systemic diseases may cause the immune system to react inappropriately or may introduce inflammatory mediators into the ocular tissues, resulting in inflammation of the retina.

For example, diseases like feline infectious peritonitis (FIP) and systemic lupus erythematosus (SLE) can have significant effects on the retinal layers and can lead to uveitis or inflammatory responses.

While drug-associated conditions, vascular diseases, and optic nerve damage can impact eyesight and lead to other ocular pathologies, they do not typically initiate direct retinal inflammation as commonly as systemic diseases do, making systemic disease the more accurate choice in the context of retinal inflammation.
