A pinhole occluder is an opaque disk with one or more small holes through it, used by ophthalmologists, orthoptists and optometrists to test visual acuity. The occluder is a simple way to focus light, as in a pinhole camera, temporarily removing the effects of refractive errors such as myopia. Because light passes only through the center of the ...
Any pathological process in the visual system, even in older humans beyond the critical period, will often cause decreases in visual acuity. Thus measuring visual acuity is a simple test in accessing the health of the eyes, the visual brain, or pathway to the brain. Any relatively sudden decrease in visual acuity is always a cause for concern.
An occluder is placed over the eye that is not being tested (e.g.: over the left eye, to test the right eye's vision). A pinhole occluder is then placed before the patient's eye, and their vision is then tested again (each eye separately) to determine if the patient's poor visual acuity is a result of optical irregularities, or pathological issues.
The Maddox rod test can be used to subjectively detect and measure a latent, manifest, horizontal or vertical strabismus for near and distance. The test is based on the principle of diplopic projection. [1]
According to a 2017 paper, [3] another hypothesis of the effectiveness of binasal occlusion in the treatment of Post Trauma Vision Syndrome, is the tape provides a stationary reference point that the brain can use to help decode the incoming visual information. The term Visual Motion Sensitivity is coined in this paper.
A U.S. judge overseeing an auction of shares in the parent of Venezuela-owned Citgo Petroleum on Monday agreed to reopen a data room to allow potential buyers to prepare new bids, a court document ...
In 3D computer graphics, Potentially Visible Sets are used to accelerate the rendering of 3D environments. They are a form of occlusion culling, whereby a candidate set of potentially visible polygons are pre-computed, then indexed at run-time in order to quickly obtain an estimate of the visible geometry.
A California woman was fatally shot by her 2-year-old toddler, leading to the arrest of her boyfriend who is accused of failing to properly store the weapon, Fresno police said this week.
