Endophthalmitis

Endophthalmitis is an inflammation of the interior of the eye. It is a possible complication of all intraocular surgeries, particularly cataract surgery, with possible loss of vision and the eye itself. Infectious cause is the most common and various bacteria and fungi have been isolated as the cause of the endophthalmitis. Other causes include penetrating trauma, allergic reaction, and retained intraocular foreign bodies. Intravitreal injections expose patients to the risk of endophthalmitis, but with an incidence rate usually less than .05%. Endophthalmitis is an inflammation of the interior of the eye.

Other causes include penetrating trauma, allergic reaction, and retained intraocular foreign bodies. Intravitreal injections expose patients to the risk of endophthalmitis, but with an incidence rate usually less than .05%. In cases of endophthalmitis, one usually finds a history of recent intraocular surgery or penetrating ocular trauma. In some cases of endogenous endophthalmitis—particularly in immunocompromised patients or those with diabetes—the spread of infection may have been hematogenous (via the blood-stream). Endophthalmitis is usually accompanied by severe pain, loss of vision, and redness of the conjunctiva and the underlying episclera. Hypopyon can be present in endophthalmitis and should be looked for on examination by a slit lamp. An eye exam may be indicated in severe forms of candidiasis. 1-3% of cases of candidal blood infections include endophthalmitis. Late-onset endophthalmitis is mostly caused by Cutibacterium acnes.
