Purpose:
The purpose of this study was to evaluate the feasibility and safety of office-based vitreoretinal procedures.
Methods:
Patients undergoing primary elective pars plana vitrectomy were elected for surgery in an office-based setting (performed in a minor procedure room under topical anesthesia [TA] and oral anxiolysis). Rates of surgical objective achievement, surgical timing, and comfort were recorded to evaluate feasibility. Intraoperative and postoperative adverse events were assessed to evaluate safety.
Results:
Office-based vitrectomy surgery was performed in 34 eyes of 30 patients. The mean surgical time was 12.351 ± 8.21 min. Surgical objectives were achieved in 100% of cases. The mean best-corrected visual acuity improvement was 9.08 letters (P < 0.0001). During most parts of the procedure, no patient reported pain or discomfort. Neither intraoperative nor postoperative adverse events were reported until the final follow-up visit.
Conclusion:
Office-based vitreoretinal procedures under TA could be as feasible and as safe as vitreoretinal procedures under conventional anesthesia.

Specialized Care Centers and Settings-II
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
