Design and construction of a novel transpalpebral ophthalmic tonometer
Glaucoma -- a degeneration of the optic nerve- is a leading cause of blindness which is primarily caused by large fluctuations in intraocular pressure (lOP) known as diurnal variations. Because these peak in the early morning dropping off rapidly, a self administrable and inexpensive lOP home …

The Use of Preclinical Models to Improve the Treatment of Retinoblastoma
… of five modalities, retina camera, optomotry, tonometer, ultrasound and MRI, was done with retinoblastoma mice. We determined the feasibility of each technique. It was found that the retina camera could detect the tumor the earliest in a high throughput manner. Additionally, the tonometer and …
