Eyelid pressure and contact with the ocular surface.
Purpose. To investigate static upper eyelid pressure and contact with the ocular surface in a group of young adult subjects. Methods. Static upper eyelid pressure was measured for 11 subjects using a piezoresistive pressure sensor attached to a rigid contact lens. Measures of eyelid pressure were derived from an active pressure cell (1.14-mm square) beneath the central upper eyelid margin. To i...
متن کاملCorrection: Ocular Surface Displacement with and without Contact Lenses during Non-Contact Tonometry
PURPOSE To evaluate the displacement of the central ocular surface during non-contact tonometry with and without soft contact lenses and determine the factors associated with the displacement of the central ocular surface and intraocular pressure (IOP) reading changes caused by wearing soft contact lenses (CLs). METHODS One eye each in 21 subjects was studied. The cornea was photographed usin...

Effect of Contact Pressure and Frequency on Contact Heat Transfer Between Exhaust Valve and its Seat
The hot gases produced by the internal combustion engines passes through the exhaust valve and causes high temperatures in the exhaust valve and its seat. To avoid damaging the exhaust valve, heat must be transferred from the valve to its seat during the contact they make at the opening and closing cycle. Heat transfer rate from the exhaust valve to its seat is a function of many factors. One o...
متن کاملEvaluation of intra ocular pressure and hemodynamic change following intubation with Maccoy, Macintosh and Video laryngoscope
Background & Objective: The induction of anesthesia, laryngoscopy and endotracheal intubation can be associated with adverse hemodynamic response and increased intraocular pressure. The aim of this study was to evaluate intraocular pressure and hemodynamic changes after laryngoscopy and endotracheal intubation with three methods of laryngoscopy (Macintosh, Maccoy and Video laryngoscope).Materia...
