Safety Profile of Intravitreal Injections in the Injection Cabinet: No Cases of Endophthalmitis Seen After 7238 Injections

Objectives: The present study evaluates the rate of endophthalmitis in intravitreal injections (IVI) performed in a modular injection cabin that could be easily sited in a closet in an office environment, and the performance tests of the cabin in terms of heating, ventilation, and air conditioning (HVAC). Methods: The injections were given over approximately 18 months in the cabin and the demographics of the patients were screened retrospectively, and the cabin was subjected to HVAC tests. Results: A total of 7,238 injections were performed in the defined period, and no cases of endophthalmitis were encountered (0%). The results of the airflow and flow rate, particle count, pressure difference, decontamination time, light, moisture, and heat tests were all found to be above the standard defined by the International Organization for Standardization (ISO). Conclusion: An injection cabin is a practical modular construction that can be easily sited in any space without the need for special climatization, and provides a sterile and safe environment for IVI.
