Might turn white: An advanced untreated cataract will eventually turn white in the pupillary space. If still untreated, some will dissolve and lose the white color but more often will rupture and set up a terrific inflammation inside the eye. In this era, cataract removal is so predictable and safe that advanced cataracts should be rare. ...Read moreSee 4 more doctor answers

Lowered color perception can be inherited (many forms), can result from advanced loss of retinal cells, inherited retinal disease, and some forms occur due to CNS injury. There are excellent tests for the various types and they can be functionally ...Read more
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
Color perception: Color vision can be altered in the usual way by inherited defects in the color perceptive elements of the retina. But advanced retinal disease like diabetes can impair color recognition; and changes in the color of the lens, and a few odd types of strokes and optic nerve disease all can alter color recognition patterns. Your ophthalmologist can sort this out for you. ...Read moreSee 1 more doctor answer

Loss of color vision: In the retina of your eye, there are rods (for seeing in the dark) and cones (for seeing color and fine detail). There are three types of cones, similar to the three primary colors, and the color blindness test checks subtle differences between shades to see if you are missing cones of one of the color types (usually red or green). But usually you are not aware of any problem seeing things. ...Read more
When looking at text on screen, colours of individual letters change periodically - from black to navy blue. Not computer; overworking eyes? Diabetes?
Macular issue: The variations in the colors of the letters localizes the problem area to the central retina, the macula lutea, aka the fovea centralis. Diabetes is not impossible but not likely without a history. A retinal toxicity to the antibiotics for h. Pylori is also possible. A retina specialist or general ophthalmologist is the starting point for a dilated examination of the back of your eyes asap. ...Read more
Normal field vision test. Dilated optic discs small w/slight asymmetry. Suspicious oct scan. Eye pressure 27. Family history. Suspect for glaucoma?
Color confusion: The tests are designed usually with dots of color along the axis which a color deficient person might confuse them. So by lacking the ability to pick out certain colors, the number or figure will not stand out from the background of dots and so will not be recognized. Some tests are sophisticated enough to indicate which type of color blindness is present. ...Read more
