Superior Laser Peripheral Iridotomy Confers Greater Risk of Negative Dysphotopsias than Temporal Laser Peripheral Iridotomy.

Purpose: Laser peripheral iridotomy (LPI) is largely used as the first course of action to treat primary angle-closure (PAC). Previous literature has long been divided on the relationship between iridotomy position and dysphotopsia onset. The current study investigates whether there is a correlation between iridotomy position, temporal versus superior, and new onset post-operative dysphotopsia rates.

Comparison of Disposable Goldmann Applanation Tonometer, ICare ic100, and Tonopen XL to Standards of Care Goldmann Nondisposable Applanation Tonometer for Measuring Intraocular Pressure.

Purpose: To compare intraocular pressure (IOP) measurements by Goldmann applanation tonometer (GAT), disposable Goldmann applanation prism, ICare, and Tonopen.

Materials And Methods: A total of 74 patients with varying glaucoma status were examined in our outpatient clinic and IOP was measured with 3 tonometers. The disposable Tonojet prism (dGAT), Tonopen XL, and ICare ic100 were compared with the GAT.

Directed Therapy: An Approach to the Improved Treatment of Exfoliation syndrome.

Exfoliation syndrome (XFS) is an age-related, generalized disorder of the extracellular matrix characterized by the production and progressive accumulation of a fibrillar extracellular material in many ocular tissues and is the most common identifiable cause of open-angle glaucoma worldwide. Exfoliation syndrome plays an etiologic role in open-angle glaucoma, angle-closure glaucoma, cataract, and retinal vein occlusion. It is accompanied by an increase in serious complications at the time of cataract extraction, such as zonular dialysis, capsular rupture, and vitreous loss.

Directed therapy for exfoliation syndrome.

Exfoliation syndrome (XFS) is an age-related disorder of the extracellular matrix that leads the production of abnormal fibrillar material that leads to elevated intraocular pressure and a relatively severe glaucoma. Exfoliation material is deposited in numerous ocular tissues and extraocular organs. XFS is associated with ocular ischemia, cerebrovascular disease, neurodegenerative disease and cardiovascular disease.

Iris morphologic changes related to alpha(1)-adrenergic receptor antagonists implications for intraoperative floppy iris syndrome.

Purpose: To identify iris structural alterations associated with intraoperative floppy iris syndrome (IFIS) in patients using systemic alpha(1)-adrenergic receptor antagonists (alpha-1ARA).

Design: Cross-sectional study.

Participants And Controls: Twenty-nine patients with current or past treatment with any systemic alpha-1ARA and 22 untreated controls.

Photodynamic therapy for focal retinal pigment epithelial leaks secondary to central serous chorioretinopathy.

Purpose: To report the use of photodynamic therapy with verteporfin as a treatment for patients with focal retinal pigment epithelial leaks secondary to central serous chorioretinopathy (CSC).

Design: Noncomparative, nonrandomized, retrospective interventional case series.

Participants: Nine eyes of 9 symptomatic patients with acute focal retinal pigment epithelial leaks secondary to CSC, confirmed with fluorescein angiography, evaluated at 1 of 3 referral retina practices.

Cardiac arrest following anaesthetic induction in a world-class bodybuilder.

This is a report of a 41-year-old professional male bodybuilder with a history of active anabolic-androgenic steroid abuse and a normal echocardiogram two years prior to admission who experienced a near-fatal arrhythmia during anaesthetic induction for elective orthopaedic surgery. The patient had severe concentric left ventricular hypertrophy, diffuse left ventricular hypokinesis, decreased ejection fraction and inducible monomorphic ventricular tachycardia. A single-chamber cardioverter/defibrillator was inserted.

HIV-associated retinopathy in the HAART era.

Background: The effectiveness of highly active antiretroviral therapy (HAART) in restoring immune function in patients with acquired immunodeficiency syndrome (AIDS) has led to changes in the incidence, natural history, management, and sequelae of human immunodeficiency virus (HIV)-associated retinopathies, especially cytomegalovirus (CMV) retinitis.

Methods: The medical literature pertaining to HIV-associated retinopathies was reviewed with special attention to the differences in incidence, management strategies, and complications of these conditions in the eras both before and after the widespread use of HAART.

Results: In the pre-HAART era, CMV retinitis was the most common HIV-associated retinopathy, occurring in 20%-40% of patients.
