## What is MaculaTester?

The MaculaTester® - A New Way to Monitor Visual Function!

Diseases that affect the macula (the center of the retina) including macular degeneration and diabetic retinopathy are the main causes of blindness worldwide. The best defense against these macular diseases is early detection. 

This simple test of your vision can alert you to early changes that may indicate a problem with your macula caused by diabetes or macular degeneration.

The MaculaTester (Pat. No. 8,047,652), is an INTERACTIVE version of the Amsler Grid - the standard test used by eye doctors to test 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 it as early as possible - while it is still treatable. 

Most doctors give their patients a card with an Amsler Grid to test themselves at home between eye exams. Unfortunately, many patients loose it or forget to use it.

The MaculaTester performs the same function as the Amsler Grid but with several distinct advantages:

• 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.

• It resides on your iPhone, iPad, or iPod Touch - so you won't lose it.

• It reminds you to perform the test at regular intervals - so you won't forget to use it.

* This app is intended for use only as an early screening test for macular dysfunction. It is not designed or intended to be used as a tool to diagnose macular degeneration, diabetic retinopathy or any other disease process. This test is not a substitute for an examination by a qualified eye care professional.

### 2/5 — Difficult to use

*2024-05-15*

It is really difficult to get to previous results. Not an easy app to use to track changes

### 1/5 — Does not work.

*2023-03-19*

I attempted several times to get a reading on my left eye. I have followed the instructions but Every time I get a message about my right eye when saving. Wasted purchase.

### 1/5 — No value

*2021-10-02*

Absurd to pay for such app

### 1/5 — Can't get it to save

*2019-01-12*

I take the test but can't get the app to save the results.

**Developer response:** The app saves results when you mark an area of distortion on the screen with your finger or a stylus. That way you can compare the size of the area of distortion when you repeat the test at a later date to look for progression. 

If you do the test and do not see any distortion there is no need to save a normal result so the app does not give you the option to save it.

### 5/5 — Simple & Easy

*2018-04-12*

This app is great for monitoring the history of your eye condition. I used to try it with paper Amsler grids but going back to view the history was never easy/accurate. Trying to remember if there were any changes s week to week was not effective either. Once a week I use this app, save the results for both eyes then can swipe between weeks to look for changes. I also bring it in to the Dr and let him review it as well. Great app.

### 5/5 — Great new version!

*2018-02-04*

This has always been a great App for those of us with conditions that affect the macula. This new version fixed the few issues I had with the previous one. It allows you to compare results in a better way with the slider, it allows you to delete a previous saved result and - most importantly - it allows you to set up reminders so you don’t forget to test yourself. Great job!

### 4/5 — Does not work on 6+

*2015-03-16*

Would not register. Would not accept any input. "App Support" is a doctor's website in Puerto Rico with no mention of the app. 

How do I get my money back?

*2014-07-21*

### 1/5 — Rubbish

*2012-07-09*

Does not allow you to record anything.
Also results differ when using white background or using black background so do not waste your money.
