Incoming information from the retina is channeled into two pathways in the brain's visual system: one that's responsible for ...

Visual field examination can provide unusual visual field loss patterns, such as ‘cloverleaf’ visual fields. One child I saw a few years ago somehow always reported a number one higher or lower than ...

Integrating large-field stimulation with a retinotopic atlas, this study introduces an fMRI-based method for measuring contrast sensitivity across the visual field. Retinotopy was assessed using pRF ...

This may be particularly useful for those with central visual field loss without the requirement of stable fixation or subjective motor responses. (2) More sensitive measure: The use of slope to ...

Goldmann visual field (GVF) examination showed a junctional scotoma pattern with right upper quadrant loss in the right eye and central scotoma in the left eye, indicative of pressure on the juncture ...

Purpose of a Visual Field Test A visual field test measures how well you can see above, below, and on either side of you. This test can help diagnose diseases of the eye, optic nerve, and central ...

Non-weighted (mean defect, loss variance), variability-weighted (mean deviation, pattern standard deviation (PSD)) and graphical (cumulative defect (Bebie) curves) indices were computed.

Visual field progression patterns are similar between eyes with glaucoma and eyes with ocular hypertension, according to a study published in Eye. Carefully monitoring these known areas of progression ...

Background/aims A recent study has shown that the paracentral upper visual field in the macular region is often affected in glaucoma and suggested that two test locations within the central 10° should ...
