Efficiency of phacoemulsification handpieces with high and low intraocular pressure settings.

Purpose: To compare the efficiencies of the Active Sentry handpiece at low IOP (20 mmHg) to the Ozil handpiece at high IOP (50 mmHg).

Setting: Private practice (Medford, OR, USA).

Design: Single site, prospective, double-arm, randomized, contralateral eye study.

The Cutting Efficiency of a Hybrid Phacoemulsification Tip Using High and Low Intraocular Pressure Settings in Different Grades of Cataract.

Purpose: To evaluate the efficiency of a hybrid tip in removing cataract grade 3 and 4 in high and low intraocular pressure (IOP) settings.

Methods: This was a randomized, prospective, double-arm contralateral eye study. One randomized eye of each subject had phacoemulsification with high IOP settings (50 mmHg) while the other eye had phacoemulsification with low IOP settings (20 mmHg).

A Narrative Review of Common Uses of Ophthalmic Ultrasound in Emergency Medicine.

Background: The timely evaluation of ocular conditions in the emergency department (ED) can be difficult due to a general lack of specialized equipment, trained personnel, and the time-sensitive nature of emergent ocular conditions. Recently, the use of ocular point-of-care ultrasound (POCUS) has been shown to be particularly useful in the ED. POCUS can be used to promptly diagnose various ocular pathologies, which include ocular trauma, vitreous hemorrhage, central retinal artery occlusion, and retinal detachment.

First Described Case of Anterior and Posterior Segment Crystals in Phacolytic Glaucoma.

Phacolytic glaucoma is an open-angle glaucoma that occurs when lens proteins from hypermature cataracts seep through an intact anterior capsule and induce obstruction of the trabecular meshwork by inflammatory cells. We review the case of a 66-year-old man who presented with acute pain, a hypermature cataract, prominent anterior chamber crystals, and elevated intraocular pressure. After cataract surgery was performed, iridescent crystals were noted in the posterior chamber.

BRANCH RETINAL ARTERY OCCLUSION ASSOCIATED WITH PARACENTRAL ACUTE MIDDLE MACULOPATHY IN A PATIENT WITH LIVEDO RETICULARIS.

Purpose: To report the occurrence of a branch retinal artery occlusion with paracentral acute middle maculopathy in an otherwise healthy young man with a history of livedo reticularis (LR).

Methods: Retrospective case report.

Patients: A 21-year-old man with a history of LR being treated with pentoxifylline developed an acute branch retinal artery occlusion with initial best-corrected visual acuity at presentation of 20/80.
