exploration of intraocular pressure measurement device

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2005.Includes bibliographical references (leaves 70-71).Glaucoma, caused by an elevated intraocular pressure (IOP), is one of the leading causes of blindness. As constant monitoring of IOP is essential in the treatment of glaucoma, the IOP measurement techniques described in patents and patent applications since 1950 are examined. None of the methods provides a simple and comfortable approach for patients to self monitor their IOPs at different times throughout the day. A through-the-eyelid tonometry method is proposed to address the deficiencies of the previous techniques. Two through-the-eyelid tonometers are designed, and parts of the prototypes are built.by Flora T. Chiu.M.Eng
