Patients with acute endophthalmitis usually present with sudden onset of symptoms, which may include severe eye pain, redness, swelling, and decreased vision. Other symptoms can include sensitivity to light (photophobia), discharge from the eye, and a feeling of pressure inside the eye. These symptoms can develop rapidly, often within a few days of surgery or injury.

The workup for suspected acute endophthalmitis involves a thorough clinical examination by an ophthalmologist. This includes checking visual acuity and examining the eye with a slit lamp to assess the anterior chamber and vitreous humor. A sample of the vitreous or aqueous humor may be taken for laboratory analysis to identify the causative organism. Imaging studies, such as an ultrasound of the eye, may also be used to assess the extent of inflammation.

Treatment for acute endophthalmitis typically involves the immediate administration of antibiotics, often injected directly into the eye (intravitreal antibiotics) to combat the infection. In some cases, systemic antibiotics may also be prescribed. If there is significant inflammation or debris in the eye, a surgical procedure called a vitrectomy may be necessary to remove infected material. Prompt treatment is crucial to preserve vision.

The prognosis for acute endophthalmitis depends on several factors, including the causative organism, the speed of diagnosis and treatment, and the patient's overall health. While some patients may recover with minimal vision loss, others may experience significant and permanent impairment. Early intervention generally improves outcomes.

Acute endophthalmitis is most commonly caused by bacterial infections, though fungal infections can also occur. The condition often follows eye surgery, such as cataract surgery, or trauma that introduces bacteria into the eye. Less commonly, it can result from an infection spreading from another part of the body (endogenous endophthalmitis).

Acute endophthalmitis is a rare condition, with an incidence of approximately 0.04% to 0.2% following cataract surgery, which is the most common surgical procedure associated with this condition. The risk is higher in cases of trauma or in patients with compromised immune systems. The condition can affect individuals of any age, though it is more common in older adults due to the higher prevalence of eye surgeries in this population.

The pathophysiology of acute endophthalmitis involves the invasion of the eye's internal structures by microorganisms, leading to an inflammatory response. This inflammation can cause damage to the retina and other vital structures within the eye, resulting in vision loss. The rapid progression of inflammation is due to the eye's unique immune environment, which is less capable of fighting infections compared to other body parts.

Preventing acute endophthalmitis involves meticulous surgical techniques and postoperative care. Prophylactic antibiotics may be administered before and after eye surgery to reduce the risk of infection. Maintaining a sterile environment during surgery and educating patients on recognizing early symptoms of infection are also crucial preventive measures.

Acute endophthalmitis is a serious eye condition characterized by rapid inflammation due to infection. Prompt recognition and treatment are essential to prevent permanent vision loss. While it is a rare complication of eye surgery or trauma, understanding its presentation, workup, and treatment options can significantly improve patient outcomes.

If you or someone you know has recently undergone eye surgery or experienced eye trauma and is experiencing symptoms such as severe pain, redness, or vision changes, it is important to seek medical attention immediately. Early diagnosis and treatment are critical in managing acute endophthalmitis and preserving vision. Always follow your healthcare provider's instructions for postoperative care and report any unusual symptoms promptly.
