In ophthalmology, examinations and interventions are performed at a very close distance.
The nose is the primary source of droplets, through which any type of infection can be transmitted in the form of an aerosol, including current SARS-CoV2. It has been registered that even with the use of masks, the drops can reach a distance of 70 cm.
In the offices dealing with the pathology of the posterior segment of the eye, we are in contact with patients at high risk for COVID 19: elderly people, diabetics, obese people with heart problems, arterial hypertension and their complications and numerous other comorbidities.
The Japanese Association for Respiratory Infections indicates the importance of Povidone iodine solution.
