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.

The role of bedside ultrasound in pretherapeutic and posttherapeutic lumbar puncture in patient with idiopathic intracranial hypertension.

Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is often a debilitating condition characterized by headaches, blurry vision, nausea, and vomiting. Lumbar puncture (LP) is an essential component of the diagnostic and therapeutic approach; however, the procedure itself can cause postlumbar puncture headache. In addition to the clinical presentation, the use of bedside ultrasound to measure the optic nerve sheath diameter may aid in differentiating the 2 conditions.We hereby report a case of a 33-year old woman with known IIH who presented with recurrent headache after the initial therapeutic LP.
