We preoperatively divided 58 ophthalmic @entity2743 @entity1 into types I and II categories before two-wall orbital decompression. Type I classification was given to @entity1 who had no @entity892 and essentially normal versions. Type II classification was assigned to @entity1 with restrictive motility loss and @entity892 within 20 degrees of the primary position. Ocular motility was assessed before and after two-wall orbital decompression. Only one of 25 type I @entity1 (4%) experienced @entity892 after orbital decompression, while seven of 14 (50%) (p = 0.001) type II @entity1 without preoperative primary-position @entity892 had primary @entity892 postoperatively. Of 12 type II @entity1 who had preoperative primary-position @entity892 , @entity5971 increased by an average of 12.4 diopters postoperatively. Vertical deviation increased an average of 13.4 diopters for 10 @entity1 who underwent unilateral two-wall decompression. The likelihood of new or worsening @entity892 in all type II @entity1 following decompression was 22 of 36 (61%). We conclude that adverse motility change following two-wall orbital decompression is rare in @entity66 @entity1 , but it occurs 61% of the time in @entity66 @entity1 . Predicting preoperatively which @entity1 are likely to develop adverse motility change and @entity892 may help clarify indications and risks of orbital decompression surgery in @entity1 with ophthalmic @entity2743 .
