An All-Digital, Binocular, Indirect Virtual Video Ophthalmoscope: A Novel Approach to Retinal Examination and Photography.

Purpose: We describe a novel method of digital, virtual-reality based binocular indirect ophthalmoscopy which allows for simultaneous stereoscopic recording of the examination with the potential of real-time anatomic correction of the retinal view.

Materials And Methods: A provisional prototype of the all-digital, binocular, indirect virtual stereo video ophthalmoscope was designed consisting of a generic LED light source and two synchronized closely spaced side-by-side minicameras which are connected to a processor, storage media (a Samsung note-9 android smartphone in the current provisional prototype), and a virtual reality set (VISIONHMD Bigeyes H1 3D Video Glasses, in the current prototype). A custom designed android application was developed to capture the examination media and allow optional real-time anatomical correction of the examination view.

A Novel Cost-Effective Simulation Model for Continuous Curvilinear Capsulorhexis.

Introduction: We describe and validate a low-cost simulation model for practicing anterior lens capsule continuous curvilinear capsulorhexis (CCC).

Methods: A simulation model for CCC was developed from widely available low-cost materials. Ophthalmologists attending the annual scientific meeting of the Research Institute of Ophthalmology, Giza, Egypt, were asked to perform a five CCC model task and then anonymously answer a questionnaire that assessed the realism and training utility of the model using a five-point Likert scale (1 = unacceptable, 2 = poor, 3 = acceptable, 4 = favorable and 5 = excellent).

Ocular Complications Following Vaccination for COVID-19: A One-Year Retrospective.

Vaccination efforts as a mitigation strategy in the corona virus disease 2019 (COVID-19) pandemic are fully underway. A vital component of understanding the optimal clinical use of these vaccines is a thorough investigation of adverse events following vaccination. To date, some limited reports and reviews have discussed ocular adverse events following COVID-19 vaccination, but a systematic review detailing these reports with manifestations and clinical courses as well as proposed mechanisms has yet to be published.
