Characteristics and Management of Vertical Deviations in an Urban Academic Clinic: A
Retrospective Analysis
Background: The purpose of this retrospective study was to determine the characteristics of patients with vertical oculomotor deviations, and furthermore to examine the efficacy of optometric vision rehabilitation (OVR) as a treatment for vertical deviations. Methods: Medical records were reviewed for 512 patients who were diagnosed with a vertical deviation at the University Eye Centerm (UEC) at the SUNY State College of Optometry from the years 2005-2010. Presenting complaints, referral source, and descriptions of the deviations were analyzed. Previous interventions were noted, and treatment recommendations were reviewed. Of those patients for whom OVR was recommended, the initial therapeutic results and follow-up were evaluated. Results: The most common presenting complaint was diplopia (“double vision”) (42%), and the most common referral source was a self-referral (59%). The most prevalent vertical deviation was a constant, comitant, hypertropia of small magnitude (1-5Δ). Concurrent horizontal strabismus was present in 52% of the patients. Previous interventions included extraocular muscle surgery, prism, and OVR. Treatment recommendations included prism (37%), OVR only (22%), or OVR and prism (14%). For those patients who were recommended for OVR only, 37% completed the OVR. Of those who were recommended OVR and prism, 39% completed the OVR. Symptoms were reduced in 78% of those who either completed OVR only or received OVR and prism treatment. More of the patients who completed the OVR showed maintenance of their improvements (38% of OVR only and 44% of OVR and prism) at greater than one year follow-up. Conclusions: The present findings provide critical information that can be used for optimal referral and treatment. Optometric vision rehabilitation provided an effective treatment option.
