Diseases that affect the macula (the center of the retina), including macular degeneration and diabetic retinopathy, are the main causes of blindness worldwide. Up to 80% of patients with diabetes lose vision due to retinopathy and up to 20% of patients with age related macular degeneration (AMD) go blind.
The best defense against these conditions is early detection.
This simple test of your vision can alert you to changes that may indicate a problem with your macula caused by diabetes of macular degeneration.
The MaculaTester (Patent # 8,047,652), is an interactive version of the Amsler Grid - the standard test used be eye doctors to check macular function for over 50 years.
Image distortion is
often the first visual change that patients notice when the condition is starting or advancing. Since the distortion can be subtle and difficult to notice at first, the amsler grid is used to help detect AMD as early as possible while it is still treatable.
give their patients a card with an amsler grid on it to test themselves at home
between eye exams. Unfortunately many patients loose it, or forget to use it.
The MaculaTester is an
electronic test that serves the same function as the Amsler grid but with
several distinct advantages:
1) It is interactive - allowing you to
record the area of distortion by touching the screen. The recorded image is
saved with date and time so you can show it to your doctor, as well as compare
to previous images to look for any changes.
2) It resides on your iPhone / iPod Touch -
so you won't lose it.
3) Our free "push notification" feature reminds you to
perform the test at regular intervals - so you won't forget to use it.
You can find the MaculaTester on Apple's iTunes Store. Just click on the "Available on the App Store" button.
