How It Works

01

Provide the required information, and make sure to keep your ruler handy.

02

Do the test while covering the eye opposite to your dominate hand, and submit your results in the google form!

03

Do the test in another 5-6 months to see how it has progressed and whether you are at risk for glaucoma(please read the Legal Disclaimer before making any medical decisions)

OUR PURPOSE

Knowing if you are at risk of glaucoma prevents blindness through early detection and timely treatment

What is Glaucoma?

Glaucoma is a serious eye disease that can lead to blindness and is challenging to detect early due to its lack of symptoms in the initial stages. In glaucoma patients, the optic disc (a structure in the eye) may become abnormally enlarged. This project seeks to develop and validate a computer-based tool for detecting early signs of glaucoma.

What does our Project do?

The tool operates by guiding participants through a series of measurements, including eye-to-screen distance, blind spot size in various directions, and demographic details such as age, gender, ethnicity, and dominant hand. Each participant completes ten measurements at varying distances. The collected data is used to estimate optic disc size, and the consistency of these results is accurately evaluated.

Risk Factors

This study involves NO significant risks or discomfort. It is non-invasive, minimally risky, and relies solely on standard tools for measurement.

Come Back later!

Make sure to check back and take the test again in a few months!

Instructions

The participant sits in front of the computer.
Enter the computer display’s width, height, horizontal and vertical resolution, and the eye-to-screen distance.
A fixation target is displayed on the screen for the participant to focus on.
The participant’s dominant-hand-side eye is aligned parallel to the target.
Measure and record the eye-to-target distance in centimeters.
The participant covers the opposite eye (non-dominant side) with their hand.
Using the uncovered eye, the participant continues focusing on the target throughout the experiment.
A black dot appears on the screen (on the right for right-handed participants). It moves toward the target, and the participant identifies the location where the dot becomes invisible (blind spot).
Press space when the dot enters the blind spot and space again when it exits. For the final dot, which moves vertically, press the space bar and repeat the same steps as for the horizontal ones.
The computer calculates the blind spot’s vertical and horizontal dimensions in centimeters.
Repeat the process five times, changing the distance between the targets for each trial.
The program records the blind spot dimensions and the target distances for analysis.
Once the test is complete, the participant collects the horizontal (H) and vertical (V) values.
Participants complete a Google Form with demographic information (age, gender, ethnicity) and input their test results and distances for data analysis.
