Variable angle strabismus can be inward (esotropy) or outward (exotropy) or vary from esotropy to exotropy. Mental retardation has been found to be related to strabismus in 50% or more of the cases and 35% of these had variable angle strabismus. A total of 61 patients with variable angle strabismus were studied finding 55.7% with esotropy, 36% exotropy and 8.2% varying from esotropy to exotropy. Of those under study, 64% were females and 77% under five years old. No accommodative factors were found in any of the patients. The best results were obtained through surgery (recession plus Faden) previous rehabilitation.
可变角度斜视可为向内（内斜视）或向外（外斜视），或从内斜视转变为外斜视。已发现50%或更多病例中的智力迟钝与斜视有关，其中35%患有可变角度斜视。共研究了61例可变角度斜视患者，发现55.7%为内斜视，36%为外斜视，8.2%从内斜视转变为外斜视。在这些研究对象中，64%为女性，77%年龄在五岁以下。所有患者均未发现调节因素。通过手术（后徙加缝线固定术）及术前康复取得了最佳效果。
