PURPOSE: To evaluate the effect of symmetric recession surgery on all four horizontal rectus muscles in the treatment of @entity1 with @entity16391 and sensory @entity346 secondary to @entity4068 , dyschromatopsia and @entity18061 . METHODS: Prospectively, four @entity1 with a diagnosis of @entity16391 and eight @entity1 with sensory @entity346 were operated on. The amount of recession was determined according to the ocular alignment of the @entity1 . Electronystagmographic recordings were conducted in every @entity1 pre-operatively and post-operatively, as well as an ophthalmological examination. RESULTS: Mean age of the @entity1 at the time of the first visit was 6.7 +/- 4.2 years (range 9 months to 14 years) and mean age at the time of operation was 8.3 +/- 2.7 years (range 6-14 years). In 8 cases an equal amount of weakening of the four horizontal recti was done, whereas in 2 cases more recession on the lateral recti due to @entity5770 and in 2 cases more recession on the medial recti due to @entity5971 was performed. Mean follow-up time was 15.8 months (min. 6 months, max. 28 months). Improvement in visual function was achieved in 7 @entity1 . Amplitude decreased in 9 @entity1 . One @entity1 had a @entity227 due to progression of her primary @entity1020 . Improvement in head posture was seen in 3 @entity1 and there was no change in the head posture in 2 @entity1 . One @entity1 acquired head posture after surgery. Restriction of motility was seen in none of the @entity1 after surgery in spite of large amounts of recession. Recession of horizontal recti @entity346 and frequency in 81.8% of @entity1 . Improvement in visual function, measured as an increase in visual acuity in terms of Snellen lines, was achieved in 63.6% of @entity1 . CONCLUSION: Symmetric recession of the horizontal rectus muscles is shown to be a successful procedure to perform in @entity346 @entity1 , resulting in an increase in visual acuity and a @entity346 and frequency. It is a reliable alternative to the Kestenbaum operation and is easier to perform surgically.
