I was surprised and delighted to received this very special stereoscope card in the mail yesterday from a very special colleague and friend. You can probably do free space fusion to converge and see Louis’ hand extend toward you in friendship, from a gentleman who referred to himself as “Dad” in our profession for the better part of the last century. He was iconic in California where he practiced. The reverse of the card carries these holiday greetings:
Louis Jaques is best known for introducing binasal occlusion to the profession. It wasn’t in his first book which was published in 1936 and titled Fundamental Refraction and Orthoptics, but it was in his second one titled Corrective and Preventive Optometry published in 1950. As Dr. John Tassinari noted in his seminal article on the subject in the first issue of JBO, he referred to the tapes (which he did with black electrical tape) as bimedial covers and binocular-monocular macular covers. Dr. Steve Gallop elaborated further on the range of uses for binasal occlusion. Dr. Alissa Proctor was among the first to advance the application of binasal occlusion in TBI, and most recently Posvar and colleagues elaborated on the use of binasals for visual motion hypersensitivity as originally introduced by Ciuffreda and colleagues.
Dr. Jaques no doubt would have derived much satisfaction in seeing the traction that binasals have gained around the world. An article was published last year in the Chinese Journal of Optometry, Ophthalmology and Visual Science titled Effect of Binasal Occlusion in Children with Concomitant Esotropia which demonstrated that binasal occlusion can effectively assist the treatment of concomitant esotropia in children to a statistically significant level.
