Abstract

A wearable device for performing an electroretinogram examination on a wearer may have a housing defining a first compartment and a second compartment. Each of the first compartment and the second compartment may include: a stimulation light source; a focused light source; an active electrode configured to engage the skin of the wearer; and a reference electrode spaced apart from the active electrode and configured to engage the skin of the wearer. A processor may be communicatively coupled to the stimulation light source, the active electrode, and the reference electrode of each of the first compartment and the second compartment of the housing. A memory may be in communication with the processor. The apparatus may perform a method comprising: flashing the stimulation light source of the first compartment; and storing a signal from the active electrode of the first compartment. The housing may further include a ground electrode.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to and the benefit of US Provisional Patent Application No. 62 / 912,920, filed on October 9, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure generally relates to systems, devices, and methods for testing retinal diseases. Background technique [0004] Diabetic retinopathy (DR) is the leading cause of blindness in working-age adults. Fundus photography is a routine method for diagnosing DR. However, by the time DR is evident on fundus photographs, irreversible damage and vision loss have already occurred. Electroretinography (ERG) is a powerful tool for recording retinal function, which is used in eye clinics to diagnose or monitor retinal diseases. By detecting defects in the rod drive pathway, ERG can screen for DR at an early stage, before vision-threatening damage occurs. Because: (a) the patient's eye requir...
