Ocular ultrasound has multiple uses today: structural assessment in eye trauma, prediction of intracranial hypertension, diagnosis of retinal detachment, retinal artery occlusion, foreign body, etc.
Technique
The patient remains with his eyes closed, a copious amount of gel is applied to optimize contact, and with the linear transducer (which as we know is of high frequency so it is better for superficial structures) it is fanned in the sagittal and transverse axes (figure 1). In this way we can appreciate the different ocular structures and thus obtain fast, non-invasive and non-harmful diagnostic approaches (figure 2). It is advisable to rest the fourth and fifth fingers on the patient’s nose to have a firmer base.
