I am equally happy to report that this idiopathic trochlear nerve palsy, also called 4th nerve palsy or superior oblique palsy, can be correct through prism ‘inserts’ in my eyeglasses. To test their effectiveness a MARC technician attached some gel self-stick prisms to the inside of my progressive vision glasses.
As one can see in the pictures, the prisms appear like miniature glass jalousie shutters. Amazingly though, they actually DO fuse my visual input into one comfortable image! After you get over the annoying urge to rip off your glasses to clean them, because the lenses seem opaque or smudged, their benefits are overwhelmingly wonderful to experience. For the last two years or so, my fusional control has been deteriorating so much, that it became a serious problem. When you arrive in an airport and the overhead signs directing you to the baggage claim turn into sparkly, shapeshifting and bouncy non-sensical objects, it is frustrating and infuriating. My dizzying kaleidoscope eyes just wouldn’t stop swirling. But these prisms have stopped the kaleidoscopes!
I can’t emphasize enough, how important it is to follow your instincts, when you try to find a solution to a medical problem. Don’t let yourself be dismissed with a shrug! As a rule: funky vision and near daily headaches are not usually cured through application of artificial tear lubricants.
