Intraocular pressure measurement in cynomolgus monkeys. Tono-Pen versus manometry.

PURPOSE In living cynomolgus monkey eyes, the authors compared manometrically set and measured intraocular pressure (IOP) with simultaneous IOP readings obtained with the Tono-Pen (TP), a handheld applanation tonometer based on the Mackay-Marg principle. METHODS In three pentobarbital-anesthetized cynomolgus monkeys, IOP was set and measured manometrically after anterior chamber cannulation t...

Vizdom: Interactive Analytics through Pen and Touch

Machine learning (ML) and advanced statistics are important tools for drawing insights from large datasets. However, these techniques often require human intervention to steer computation towards meaningful results. In this demo, we present Vizdom, a new system for interactive analytics through pen and touch. Vizdom’s frontend allows users to visually compose complex workflows of ML and statist...
