Abstract:

Objective The aim of this paper was to create a Portable Gonioscopy System (PGS) that is effcient and cost-effective in documenting iridocorneal angles. Methods A 4-mirror gonioscopy prism lens was attached to a portable USB microscope with a built-in camera. The microscope was then connected to a laptop for viewing of the images. A lubricant was instilled and the portable gonioscope was placed parallel to the cornea for viewing and recording of iridocorneal angles. Images were fled and stored in a laptop. Results The portable gonioscopy system allowed suffcient viewing and recording of the iridocorneal angles. The total cost of producing the portable gonioscopy system was PHP 25,000.00. Conclusion Iridocorneal angles can be visualized and recorded using the portable gonioscopy system. This device requires skill and expertise from professional prototypist to create. Like gonioscopy, this system also has a steep learning curve. The researchers are continuously improving the device adding more features and making it more affordable and easier to use.
