Apparent Inferior Rectus Palsy with Gaze-Dependent Sensory Adaptations

Abstract/Introduction

Purpose 

This report presents a case of apparent congenital inferior rectus palsy notable for sensory adaptations that appeared to vary with direction of gaze. It is shown that readily available clinical tests and an understanding of the physiology of ocular motility can be used to help distinguish from differential diagnoses such as contralateral inferior oblique palsy or the more commonly seen Brown syndrome.

 

Case Report 

A 20-year-old male optometry student reported strabismus that had been noted at birth and was diagnosed as Brown syndrome in childhood. The Parks three-step test showed primary gaze hypertropia that increased in left gaze but the “third step” (Bielschowsky head tilt test) was not successful in establishing the apparently correct diagnosis, which was later confirmed by a Hess screen. A proposed “fourth” step by Bajandas proved to be more accurate in this case of inferior rectus palsy. Sensory tests revealed adaptation patterns that varied with gaze direction and showed a cyclotorsional element. The patient reported being relatively unconcerned about his condition as he seemed to be able to voluntarily use a form of shallow suppression to reduce awareness of diplopic images.


Conclusion/Results

Conclusions 

Although it is common to consider suppression and retinal correspondence status as hardwired and relatively constant for an individual patient, this case demonstrates that these sensory adaptations are likely to be far more complex and transitory. An understanding of both motor and sensory repercussions of ocular motility dysfunction assists differentiation between benign and sinister causes of nonconcomitant strabismus.


Testimonials


  • Vision therapy is well worth the response, time and effort. Our Son had a hard time focusing and writing neatly. After vision therapy Seth could complete a task in half the time if previously took. His abilities to focus improved greatly and so did his handwriting.

    Also, he was better at listening. As a parent, we wanted learning to be fun for our Son, and vision therapy made this possible.

  • Vision Therapy has given or son the tools he needs to be able to scan and read the written word more effectively and efficiently.

    He love working with John and these working sessions give him the motivation to gladly work on his homework assignments.

    It amazed us to see the difference in the tracking of his eyes and along a line of it's from the beginning to the end of the treatment.

    Dr. McBryar , Kristen and John  are all marvelous and we would recommend them to anyone I only wish that we would have found them sooner!

  • Prior to coming to the institute for vision development my son complained of daily headaches. Therapy has eliminated his headaches completely. I love knowing my son is able to learn pain-free for the rest of his life because of the work that has been done over just a few weeks in this office. He he absolutely loved coming that didn't even feel like going to a doctor or therapy. We are grateful for the relief he was able to find by coming here.

    Thank you!
