| Abstract |
PURPOSE
To compare the effect of combined recession and resection on ocular position. METHODS: We designed a study with three groups of white rabbits. A recession was performed by differing the amount, 9 mm, 12 mm and 15 mm, according to the group, after 12 mm resection on superior rectus muscle. Before and 1 week after the operation, distance from lower margin to upper corneal limbus was measured using photographs. RESULTS: In 12 mm recession group, the distance before and after the operation was 9.44 mm and 9.19 mm respectively, showing no statistically significant change (P=0.2344). In 15 mm recession group, the ocular position showed significant depression, from 9.13 to 7.87 mm (P=0.0017), whereas in 9 mm recession group ocular position showed significant elevation from 9.11 to 10.85 mm (P=0.0078). CONCLUSIONS: The result of this study showed that when combined resection and recession on the same extraocular muscle were made in the same amount, eye alignment at primary ocular position was kept. Furthermore this procedure enables adjustable surgery to be considerable in incomitant strabismus. |
