Dear Editor:

Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) infection associated respiratory disease – COVID-19 (2019-nCoV) is currently a pandemic involving more than 151,767 infected patients in India,[1] and over 5,404,512 cases all over the world.[2] Reports have shown the likelihood of disease transmission through the ocular secretions of patients.[3] All ocular procedures have to be undertaken focusing on protecting the patient and the medical worker. Ultrasound biomicroscopy being a high-resolution ultrasound technique which allows non-invasive in-vivo imaging of the anterior ocular segment is an inevitable investigation in ophthalmology.[4]

Technique of UBM: Ultrasound biomicroscopy is performed with patient lying in supine position. After topical anaesthesia, an eyecup is placed and is filled with a sonolucent coupling fluid to form a water bath. The probe oscillates within this open water bath.[4]

The procedure poses some risks of exposure to the examiner and the patient. We herein recommend solutions to the possible risks in [Table 1].

We also made a small but significant change for the person performing the UBM as shown in [Figure 1]a and [Figure 1]b. It is advised that these extra steps can be implemented to safeguard our medical workers and protect our patients during these trying times.
