Ocular Infections

Ocular infections, when severe, may lead to decreased vision, blindness, and even loss of the eye. Infections may be due to bacteria, viruses, fungi, worms or other parasites.

  • Endophthalmitis is usually a bacterial infection involving the inside of the eye. Bacteria may gain entrance into the eye during intraocular surgery (including eye injections).
  • Symptoms include pain, light sensitivity, redness, floaters, and vision loss. Treatment requires the injection of antibiotics into the eye, and sometimes surgery to remove the infected vitreous. Improvement in vision is often achieved. The amount of visual improvement is affected by the duration of the infection, therefor prompt evaluation is recommended if endophthalmitis is suspected.
  • Keratitis involves infection of the cornea. Bacteria, Herpes virus, and sometimes worms or parasites may be the cause. Topical antibiotic or antiviral therapy is usually necessary to treat the infection.
  • Posterior Ocular Infections are infections that commonly involve the posterior aspect of the eye including vitreous, optic nerve, retina, and blood vessels. Symptoms may be mild, but often include vision loss, floaters, and redness. ‚ÄčTreatment usually requires antibiotics or antiviral medication given systemically. Intravitreal antibiotics are utilized in selected cases.

Severe ocular infections can cause blindness and loss of the eye. Prompt and accurate diagnosis with effective treatment is necessary to preserve vision.
