Space between eyes: This is a number needed by eyeglass makers to properly space the optical centers on eyeglasses and it is the exact distance between the centers of the two pupils when the eyes fixate at a distance. It is needed on a prescription from an optical shop (termed P.D.) and you would need it if you order eyeglasses online. ...Read more
Depends : If all the visual fibers in one eye are lost, then the pupil will react depending upon the light shining upon the other eye (due to interconnected reflexes) (termed amaurotic pupil). Some can lose all vision and retain the pupillary fibers so the eye will react to light. If the eye is lowered in vision (legally blind) it can still react to light. Also some blindness is from trauma; fixed pupils ...Read more
Recent pupillary distance was measured as 65; before it was always 63, as adult. Does this reflect an underlying health issue?
Marcus-Gunn pupil: An afferent pupillary defect indicates a lesion in the afferent limb (retina or optic nerve) of the pupillary reflex. Such a lesion is best appreciated on the "swinging flashlight test." a lesion in the left optic nerve will decrease the perceived illumination in that eye, and when the flashlight is swung from the right to the left eye, the left pupil will appear to dilate slightly. ...Read more
Do I need to have a different pupillary distance value for the single vision (SV) reading, SV computer and SV reading? How determined for all three?
Pupils diameter widened permanently. Pupillary rsponse to light absolutely fine. Going through a low phase emotionally. Minor headache sometime. Worry?
People vary: Your pupils could be large, but still be normal. There are tall people and short people, it all follows a bell shaped curve. With all the problems in your side of the world, anyone would feel this. I feel it from around the world. ...Read more
My ophthalmologist said that I have afferent pupillary defect (apd 5) and hippus, what does this means?
Pupil changes: An afferent defect of the pupil refers to an abnormal dilation instead of constriction when light hits the eye. It is due to major loss of total light input in the affected eye such as massive retinal loss, optic nerve disease, etc. Hippus is a twitchy pupil jerkiness and sometimes is normal but can be seen in response to certain drugs. ...Read moreSee 1 more doctor answer
Can you tell me how actors control their pupillary response when something such as a flashlight is shone into their eyes?
They don't: It is impossible to control the pupils response to light and /or dark,. There are drops that can make the pupils get smaller and that make the pupils get bigger. These can affect the eyes ability to focus. ...Read more
We're learning about pupillary reflexes in school. What does it mean if if the reflex to light is equal but slow?
Miosis: It means both eyes are responding equally to light but slowly. ...Read more
Recent pupillary distance was measured as 65; before it was always 63, as adult. Does this mean my old specs(no chg in power) are bad for my eyes now?
My ophthalmologist said that I have afferent pupillary defect (apd 5) and hippus in my right eye, what does this means?
Group A strep: It's not quite clear what you mean without the context behind the testing. But it very well could represent group A streptococcal testing. This is common test done when someone has a sore throat to make sure he/she doesn't need antibiotics. Really on group A strep pharyngitis(sore throats) need antibiotic therapy most others resolve on their own without issue. Best of luck ...Read more
No: Sjogren's does give you a somewhat increased risk of malignant lymphoma, and it may run with a disease like lupus or scleroderma which you'd know by now whether or not you have. By itself, sjogren's is a nuisance disease. The most dangerous feature is that maybe 1% of patients get a vasculitis that can cause brain dysfunction that mimics multiple sclerosis. Be alert as it's manageable. ...Read moreSee 1 more doctor answer
RSD...: Rsd = reflex sympathetic dystophy. Other names for the same condition include sudeck's atrophy or complex regional pain syndrome (crps). The condition often occurs after an injury. Three phase bone scan is used to aid in diagnosis. Classic finding on three phase bone scan is increased peri-articular uptake. Children may show atypical presentation on three phase bone scan. ...Read moreSee 1 more doctor answer
