Brainstem Anesthesia and Cardiac Arrest Following Peribulbar Block: A Case Report and Systematic Review of the Literature.

: We report a case of brainstem anesthesia (BSA) and subsequent cardiac arrest following a routinary peribulbar block (PB) in a patient scheduled for cataract extraction and intraocular lens (IOL) implantation, thus providing a reference for further analysis of this potentially catastrophic life-threatening complication and to evaluate the current knowledge in terms of incidence, physiopathology management, and treatment of the BSA following PB. : Three databases (PubMed, Embase, and Scopus) were checked to perform a systematic review of all available studies in the English Language following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to evaluate relevant studies that clearly described BSA following BSA. : Our literature search identified 15 cases.

The Relationship between Ischemic Optic Neuropathy and Internal Carotid Artery Dissection: A Systematic Review.

: To evaluate and review the current evidence regarding the association between ischemic optic neuropathy (ION) and internal carotid artery dissection (ICAD). : We systematically reviewed studies according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines (PRISMA), searching three databases (Scopus, Pubmed, and Embase) for relevant articles that clearly described the correlation between ION and ICAD. All studies that examined the association between ICAD and the development of ION were synthesized.

A virtual model to assess maximum treatable area in LASIK and feasibility of a temporal hinge.

Purpose: To generate virtual models using different hinge locations and to investigate the advantages of a temporal hinge to a superior in LASIK.

Methods: The study design was cross sectional. An image processing software was used to construct virtual LASIK models of 56 slit lamp photos of eyes.
