Postoperative endophthalmitis is a serious eye infection that can occur after surgery. It is most commonly caused by Gram-positive bacteria, and can lead to severe visual impairment. Fortunately, there are ways to prevent this condition in older individuals. Systemic antibiotics, topical antibiotics, and antifungal medications can all be used to reduce the risk of postoperative endophthalmitis. The Endophthalmitis Vitrectomy Study (EVS) has also shown that vitrectomy can improve the chance of achieving a reasonable return of vision in patients with endophthalmitis caused by staphylococci and streptococci. The incidence of postoperative endophthalmitis in older individuals is lower than one percent. Studies have found that the risk of endophthalmitis is lower in females than in males, and that the risk is also lower in patients who have undergone cataract surgery. The incidence of postoperative endophthalmitis has been relatively stable over the years. Surgical complications are a significant factor in increasing the risk of postoperative endophthalmitis. The risk is seven-fold higher in patients who experience vitreous loss, and ocular infections are rare after cataract surgery. Intravitreal antibiotics can be used to treat endophthalmitis, but they can cause toxic reactions. Other factors that may affect the rate of postoperative endophthalmitis include the humidity of the environment and the type of incision used during surgery. To prevent postoperative endophthalmitis in older individuals, it is important to understand the risk factors for this condition. Systemic antibiotics, topical antibiotics, and antifungal medications should be used as directed by a clinician. Vitrectomy may also be recommended for certain cases of endophthalmitis caused by staphylococci and streptococci. It is also important to take steps to reduce surgical complications and ocular infections.
