To investigate the associated factors and treatment outcomes in patients with presumed noninfectious endophthalmitis after intravitreal triamcinolone acetonide (IVTA) injection.
Among 219 consecutive cases of 186 patients who had undergone IVTA injection for macular diseases, presumed noninfectious endophthalmitis was diagnosed if the patient showed severe inflammation in the anterior chamber and vitreous cavity within 7 days after injection but no organism was isolated on microbiological examination. Clinical features and previously performed surgical procedures were evaluated to assess their association with presumed noninfectious endophthalmitis using logistic regression. After surgical or medical treatment for endophthalmitis, the visual outcome was evaluated in all patients.
Noninfectious endophthalmitis developed in six of 219 eyes (2.7 %). Previous vitrectomy, history of IVTA injection, and pseudophakia were significantly associated with the occurrence of presumed noninfectious endophthalmitis after IVTA injection (p = 0.049, 0.034, and 0.009, respectively). Internal limiting membrane (ILM) peeling during vitrectomy also showed statistically significant association (odds ratio = 13.6, p = 0.017). Five of six patients (83.3 %) regained pre-injection vision.
In addition to previous vitrectomy, history of IVTA injection, internal limiting membrane (ILM) peeling, and pseudophakia may render the eye vulnerable to presumed noninfectious endophthalmitis following IVTA injection. Visual outcome shows generally good prognosis after treatment.
