Telemedicine Visual Field Test for Glaucoma Screening

Glaucoma is a major cause of preventable blindness. Of every 30 people over the age of 50, one will be affected by glaucoma, nearly half of those do not know they have the disease. Most patients with early glaucoma have normal vision and enjoy a healthy and productive lifestyle despite advancing disease.

Often, but not always, glaucoma is associated with increased intraocular pressure (IOP) in the eye. Visual field loss loss often occurs gradually over a long period of time, and is recognized only when the disease is quite advanced.

Visual field testing is a very important exam in the diagnosis and treatment of glaucoma. This 3-minute test is a virtual perimetry system.The test is fast and easy to use and will help you become aware of any significant defects in your visual field. It allows self-testing and you can use it to test your visual fields at your home computer. Ican reveal the first signs of glaucoma and will help you detect visual fields defects early.

The software uses the web camera as a virtual "photo-meter" and allows you to email your test results to your doctor. The results should be interpreted by an ophthalmologist.

The software is tested against viruses with Microsoft Security Essentials. Some antiviruses (avira) use "heuristics" methods. Heuristics provides better detection capabilities but gives a lot of false positives (https://www.avira.com/en/support-for-home-knowledgebase-detail/kbid/298). Avira is not compatible.

The software is free for non profit use. You can download the software here.
