Magnetic hysteresis loss or iron loss in soft magnetic materials accounts for approximately 30% of energy loss in electric motors. This loss results in significant energy loss globally, representing a ...
A new educational article from Modern Vision Solutions reveals a growing body of evidence that underscores the critical role ...
New research reveals how early-life blurry, low-color vision may help shape the brain’s visual pathways into specialized systems.
Aim This study evaluates if characteristics (eg, location, size, volume) of clusters of defects on an initial visual field ...
Calverley suffers from partial hemianopsia, the loss of half the visual field in both eyes, caused not by damage to the eye but to the pathways in the brain that facilitate vision.
All patients had visual field loss, half had nyctalopia, and 25% had color vision anomalies. Within 6 to 48 hours after symptom onset, 14 of 16 eyes had visual acuity (VA) of counting fingers or ...
Individuals with moderate to severe visual field loss may have difficulty performing routine tasks, such as reading, driving, and navigating environments, as well as engaging in social activities.
Density loss in the optic nerve head capillary could lead to a faster rate of visual field progression as well as an increased risk of developing event progression.
Severe vision loss in any quadrant of a person's visual field increased the chances of a crash, but loss of central vision in either eye did not increase accident risk, researchers found.
Severe vision loss in any quadrant of a person's visual field increased the chances of a crash, but loss of central vision in either eye did not increase accident risk, researchers found.
Peripheral vision loss is also known as tunnel vision or peripheral visual field loss. Peripheral vision loss affects approximately 13% of people over 65 years old. It can affect one or both eyes.
A retrospective cohort study found that rapid thinning of the ganglion cell complex was associated with central visual field decline.
