Flashes and Paisley Prints
\nBy Kate Chamberlin
\nDuring the mid-1980’s, as I was going blind, I experienced numerous episodes of dark blobs and strings meandering in my eyes. I resisted the impulse to try to catch \u201cthe flies\u201d, as they sometimes appeared to be. The doctors labeled the blobs: Floaters and said some floaters are common and natural in even healthy eyes.
\nWhen I told my eye doctors about the flashes, spirals and swirling crescents, they would pat my shoulder and say: I\u2019ve heard of that in a few patients, but I don\u2019t know what is happening.
\nI didn\u2019t tell the doctors about the images of paisley prints, but I often thought I\u2019d love to be able to transfer the unique patterns and colors I experienced onto fabric for clothing and drapes, and even wallpaper. Sometimes the pattern was more a hounds-tooth in vivid colors, but my favorite was the paisley patterns.<\/p>\n
I recently found out that the flashes have a name: photopsia. It is defined as: a subjective sensation of lights, sparks or colors due to electrical or mechanical stimulation of the ocular system.
\nNow there is also a name for my beautiful patterns: Charles Bonnet Syndrome (CBS). Charles Bonnet, an 18th century Swiss naturalist and philosopher, is credited as the first person to describe the syndrome. Like his grandfather, who had low vision and saw men, women, birds and buildings he knew were not there, Charles experienced similar phantom visions when his own vision deteriorated around 1760.
\nit is more likely to appear if you have visual acuity between 20\/120 and 20\/400. If your vision falls within these parameters, your eyes still have a great deal of power, even though they aren’t receiving or sending as many images as previously. when retinal cells become impaired and are no longer able to receive and relay visual images to the brain, the visual system begins firing off images on its own. Hallucinatory episodes can vary in duration from seconds to hours, and the symptoms can be present from days to years.
\nCharles Bonnet Syndrome is no more than a side effect of vision loss. The six criteria for Charles Bonnet Syndrome (outlined by Naville in 1873 – and still applicable today) can help you determine whether or not you are experiencing phantom vision. Ask yourself whether the images you see have the following six characteristics:
\n“1. They occur when you are fully conscious and wide awake, often during broad daylight.<\/p>\n
2.\tThey do not deceive you; you are aware that they are not real.
\n3.\tThey occur in combination with normal perception. For example, you may see a sidewalk clearly but find it covered with dots, flowers, or faces.
\n4.\tThey are exclusively visual and do not appear in combination with any sounds or bizarre sensations.
\n5.\tThey appear and disappear without obvious cause.
\n6.\tThey are amusing or annoying but not grotesque.
\nThere is no known cure or treatment, but it is important for you and others to know you\u2019re not crazy!<\/p>\n
Since ophthalmology has paid so little attention to Charles Bonnet Syndrome, many doctors don’t realize how common it really is, and some may not be familiar with it at all.
\nOh, dear Gussie! You can bet MY doctors are going to hear about this syndrome!
