Ophthalmic Physiol Opt 2021 May 4. Epub 2021 May 4.

Department of Ophthalmology, Vienna University, Vienna, Austria.

Purpose: The purpose of this study is to develop a straightforward mathematical concept for determination of object to image magnification in both phakic and pseudophakic eyes, based on biometric measures, refractometry and data from an anterior segment optical coherence tomography (OCT).

Methods: We have developed a strategy for calculating ocular magnification based on axial length measurement, phakic anterior chamber and lens thickness, keratometry and crystalline lens front and back surface curvatures for the phakic eye, and axial length measurement, anterior chamber and lens thickness, keratometry and intraocular lens power, refractive index and shape factor for the pseudophakic eye. Comparing the magnification of both eyes of one individual yields aniseikonia, while comparing the preoperative and postoperative situation of one eye provides the gain or loss in ocular magnification.

When the law influences medical practice: Potential impact of the Bouchard-Lebrun ruling on the forensic unit of the Malartic Psychiatric Hospital in Northern Quebec, Canada.

Int J Law Psychiatry 2021 Apr 28;76:101686. Epub 2021 Apr 28.

Forensic Psychiatrist, Hôpital Psychiatrique de Malartic, 1141 Rue Royale, Malartic, QC J0Y 1Z0, Canada.

The attribution of criminal responsibility in the context of substance intoxication is a matter of controversy in forensic psychiatry. In 2011, the Supreme Court of Canada ruled that Tommy Bouchard-Lebrun was guilty in the straightforward case of a crime committed while in a state of substance-induced psychosis by an individual without a history of mental disorder. However, the ruling may since have served as a precedent also for settling cases where an offence is committed while in a certain state of intoxication and where there is much more diagnostic uncertainty.

Augmented Reality in Medical Practice: From Spine Surgery to Remote Assistance.

Front Surg 2021 30;8:657901. Epub 2021 Mar 30.

Neuroscience Institute Cavalieri Ottolenghi, Orbassano, Italy.

While performing surgeries in the OR, surgeons and assistants often need to access several information regarding surgical planning and/or procedures related to the surgery itself, or the accessory equipment to perform certain operations. The accessibility of this information often relies on the physical presence of technical and medical specialists in the OR, which is increasingly difficult due to the number of limitations imposed by the COVID emergency to avoid overcrowded environments or external personnel. Here, we analyze several scenarios where we equipped OR personnel with augmented reality (AR) glasses, allowing a remote specialist to guide OR operations through voice and visuals, superimposed to the field of view of the operator wearing them.
