Pre-operative COVID-19 testing is crucial for ophthalmic surgery to protect healthcare teams. Real-time RT-PCR is recommended for elective procedures due to its higher sensitivity over Rapid Antigen Tests.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Public Health
Background:
- The oro-nasal cavity's proximity to the eye increases SARS-CoV-2 transmission risk during ophthalmic procedures.
- Protecting healthcare teams requires robust pre-operative screening protocols for COVID-19.
Purpose of the Study:
- To understand the performance of pre-operative Rapid Antigen Tests (RAT) and real-time Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) for SARS-CoV-2.
- To inform guidelines for optimal planning of ophthalmic surgeries amidst the pandemic.
Main Methods:
- A prospective descriptive study involving 204 patients undergoing elective or emergency ophthalmic surgeries.
- Pre-operative nasopharyngeal and throat swabs were tested using RAT and RT-PCR for SARS-CoV-2 viral RNA.
- Data was compiled and statistically analyzed.
Main Results:
- Two patients tested positive for SARS-CoV-2 by both RAT and RT-PCR.
- Ten patients tested positive by RT-PCR despite a negative RAT result from the same sample.
- The study population had a mean age of 51.44 ± 16.501 years.
Conclusions:
- Pre-operative COVID-19 testing is essential to prevent patient-to-healthcare worker transmission.
- Rapid Antigen Tests offer quick results beneficial for emergency surgeries.
- Real-time RT-PCR is recommended for elective procedures due to its superior sensitivity, minimizing risks to surgical teams.
