In a study published in PNAS, scientists reveal how desert ants compensate for visual loss through a rapid relearning process. These findings could inspire technological advancements to improve ...

The word “transient” may be defined as being temporary or momentary. Transient visual loss is a reversible symptom of a number of possible underlying diseases. It can be defined by its ...

Formal baseline visual field testing is advisable; abnormalities may indicate a need for additional investigation or closer follow-up. If the episodes of transient visual loss have been infrequent, ...

Visual Networks Inc. of Rockville yesterday reported a second-quarter loss of $12.3 million (39 cents per share), a significant improvement over its loss of $42.3 million ($1.54) for the same ...

A 43-year-old woman noted multiple episodes of transient visual loss on the right side. She initially thought that the episodes were in the right eye, but after cross-covering during the most ...

A pattern of visual loss may be predicted from the fellow eye in patients with bilateral sequential nonarteritic anterior optic neuropathy, according to a study. In a retrospective review, visual ...

It is a progressive disorder that can cause damage to the retina and visual cortex years after the initial measles infection. Who is most at risk for measles-related eye damage?

Important insights into the mechanisms behind Fuchs endothelial corneal dystrophy (FECD), a common cause of age-related ...

Visual loss (worse than 20/60 in both eyes) is a common cause of hallucinations, too. However, research suggests that they are more likely to appear if you have visual acuity between 20/120 and 20 ...

Background Patients with non-organic visual loss (NOVL) can take up a disproportionate amount of clinic time and clinicians often resort to expensive and prolonged investigations to ensure the ...

The search for the lesion(s) was targeted to the visual pathways posterior to the LGN, because there was bilateral visual loss with normal pupillary light reflexes. This finding places the ...

We now evaluate whether SMVL is more accurate than moderate visual loss (MVL: a single occurrence of a decrease from baseline of ⩾15 ETDRS letters) for predicting future visual loss.
