This test involves measuring tiny electrical signals generated by the eye, and so only requires that the patient look steadily at a dot on a computer screen. This technique detects early retinal damage caused by diabetes. We are now conducting research to determine whether the technique can predict future diabetic eye disease. Checking the charge on your battery. Your eye is like a battery in some ways.
Batteries come in a variety of voltages.
Healthy eyes, on the other hand, are all fairly similar to each other, and change with dark and light. Certain eye diseases, such as diabetes, can cause the eyes' voltage to drop. Little electrodes pasted to the skin near the eyes continually measure the signal from the eye as a light switches on and off. How much the signal changes in light and dark is a good signal of the strength of the battery - or the health of the eye. This study only requires a single visit to our clinic.
