Anterior chamber depth measurement using ultrasound to assess elevated intraocular pressure

Increased anterior chamber pressure also known as intraocular pressure can result from conditions such as glaucoma and trauma. The pressure in the anterior chamber is measured using tonometer. Measurement of the intraocular pressure is essential, as it requires immediate medical attention to alleviate pain and to avoid temporary or permanent damage to intraocular structures. Bedside ocular ultrasound (US) has gained popularity in recent years. It has been used to assess intracranial pressure via optic nerve sheath diameter (ONSD) and evaluate retinal detachment, vitreous hemorrhage, or pupillary reflex in a trauma patient. We report 2 cases of patients with glaucoma and a case of a patient with trauma to the eye with swelling. Anterior chamber depth measurement was conducted and compared with measurements of intraocular pressure (IOP) using a tonometer.
