In the second experiment, we recruited subjects whose naturally occurring PRL was to the left of their scotoma
and trained them to develop a TRL that was below their scotoma
With increasing distance from the fovea, the resulting scotomas
are usually asymptomatic.
Some of the complications encountered were worsening of macular edema, retinal hemorrhages, scotoma
and vitreous contraction.
When we administered the questionnaire, it soon became apparent that the original scoring instructions (the sum of all items) would not result in data that would be analyzable in a meaningful way, since few persons indicated distortions or scotomas
These areas corresponded to the areas of visual scotoma
experienced by the patients.
The highest initial IOP was observed in patients with arcuate scotoma
and the lowest in patients with preperimetric glaucoma (p = 0.0120; arcuate versus preperimetric: p = 0.0276).
Arcuate, altitudinal, or central visual field permanent scotomas
indicative of papillary involvement had persisted in our patient after treatment.
The Amsler grid test can detect scotomas
in patients with dengue related maculopathy.
(b) A visual field test on admission identified a central scotoma
in the right eye and quadrantanopia in the left (L) eye.
Visual field tests were divided into six categories: no abnormality, decreased retinal sensitivity, paracentral scotoma
, concentrically narrowed visual field, arch scotoma
, and quadrant irregularities.
He had a central scotoma
in the right eye, with initially preserved peripheral vision that rapidly deteriorated; fundoscopy was highly suggestive of panuveitis, with fine keratic granulomatous precipitates, aqueous cells, flare grade 1, and choroidal and subretinal infiltration in the posterior pole (Figure 2(a)).
To understand the effects of macular degeneration, put a fist in front of your face and there will be a blind spot (scotoma
) in the centre of your visual field.
