Glaucoma rt. eye.Humphrey field test full within normal limits.DMV peripheral vision test 50 deg left & 70 deg right. Dr says DMV test wrong.Possible?
Depends: Most Humphrey testing is 30-50 degrees from the center simply because ones that measure farther out take too long a time and most glaucoma changes start in the center. The DMV tests check a couple of horizontal points about 60 degrees and 130 degrees out. So it depends upon which testing you went through. Hopefully, with a glaucoma diagnosis, you are seeing a real doctor - an ophthalmologist. ...Read more

Micropsia: Yes, it can if the macular pucker is severe enough. Micropsia is a condition in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema,macular degeneration, and more ...Read more
They Do not hurt: Gonioscopy, ophthalmoscopy and tonometry are all part of a complete eye examination and generally do not hurt. Topical anesthetic drops are instilled in the eye at the beginning of the examination. While the bright light of ophthalmoscopy may be briefly uncomfortable, it is generally not painful. ...Read more
Read smallest line: The snellen chart is a graded series of letters or numbers smaller as you go down. The uncorrected vision is the smallest line easily read with each eye. Your ophthalmologist will present you with lenses to improve the level of the smallest line to hopefully get you to 20/20 - the standard of normal. It is a subjective test requiring your active input. ...Read more

Usually applanation: Air puff was developed for optometrists when they wisely were not permitted to use eyedrops. Because their skill level is less, they still prefer to use the air puff as it is less tricky. But the airpuff is not as accurate - it is a good screening device. Applanation is the gold standard, more accurate and precise but requires much more skill to use. So it is a tool of the ophthalmologist. ...Read moreSee 1 more doctor answer
Is it possible to get accurate visual field test with macular pucker decline in visual acuity, lights less bright & white computer screen looking gray?
Usually it is fine: You have defects in the central visual portion of your field of view - an area poorly outlined by most field testing devices. Field tests will define major defects which largely will register from the peripheral areas tested. Have you had a field tested in the past? Is there some condition being sought for with a field.? Your ophthalmologist would not order a field if he doubts the result. ...Read more
CTA: It is an intravenous contrast-enhanced CT scan with technical parameters that optimize detailed visualization of the arterial system. 3D and multiplanar data reconstructions can produce images that look similar to standard catheter angiography. From a patient's point of view, the scanning experience won't be much different from getting a standard CT scan with contrast. ...Read more
