目的：分析不同年龄段急性获得性共同性内斜视(AACE)患者的临床特征。

方法：回顾性临床病例研究。连续纳入2015-01/2022-12在北京大学人民医院手术的非Ⅰ型(AACE)患者112例。收集的患者信息包括：性别、年龄、发病年龄、手术年龄、发病持续时间(手术与发病的时间间隔)、屈光度、发病前6 mo每日近距离用眼时间、术前及术后1 mo三棱镜斜视度及Titmus近立体视。将患者按年龄分为<18岁组22例，18-45岁组67例，>45岁组23例。比较各组患者的临床资料特点。

结果：共纳入患者112例，其中男56例，女56例，手术年龄为29.50(19.25，41.75)岁，近视患者97例(86.6%)。发病前6 mo每日近距离用眼时间>8 h患者93例(83.0%)。年龄<18岁组患者发病持续时间为1.00(0.50，1.00)a，右眼屈光度为-0.75(-3.19，-0.56)D，左眼为-1.25(-2.81，-0.75)D，术前看近斜视度为30.00(18.50，80.00)PD，看远斜视度为 35.00(23.75，80.00)PD，较其余两组比较均有差异(均P<0.05)。18-45岁组患者术前看近斜视度为20.00(14.00，30.00)PD ，看远斜视度为25.00(20.00，35.00)PD，两者均较年龄>45岁组大(均P<0.05)。年龄>45岁组术后1 mo看近斜视度为-4.50(-7.50，0)PD ，术后1 mo看远斜视度为4.50(0，9.50)PD ，较其余两组更小(均P<0.05)。>45岁组患者手术成功率最高(100%)。术前立体视>45岁组比<18岁组患者更好(P<0.05)，术后1 mo立体视18-45岁组、>45岁组均好于<18岁组(均P<0.05)。

结论：AACE手术患者主要在18-45岁，斜视度特点为看远斜视度比看近大。术前年龄<18岁的患者斜视度较成人更大，但术后早期立体视较成人差。对于18-45岁AACE患者可适当增加手术量(5-10 PD)，低龄远视、术前双眼视功能尚未建立的儿童，适当保守设计。

METHODS: Retrospective analysis of clinical data. A total of 112 non-Swan type AACE patients who underwent surgery at Peking University People's Hospital from January 2015 to December 2022 were retrospectively analyzed. Clinical data were collected and the characteristics were compared, including gender, age, diopter, duration of disease, daily time spent on near work, angles of deviation before and after surgery, stereopsis, etc. According to age, patients were divided into three groups: <18 years old group(22 cases), 18-45 years old group(67 cases), and >45 years old group(23 cases). The clinical characteristics of patients were compared in each group.

RESULTS: A total of 112 patients were included in the study, comprising 56 males and 56 females, with a median age of 29.50(19.25, 41.75)years old. Among them, 97 patients had myopia(86.6%). There were 93 patients(83.0%)who spent more than 8 h on near work. The age group <18 years old had the shortest duration before surgery, with a median time of 1.00(0.50, 1.00)a, the minimum negative diopter, with a median diopter of -0.75(-3.19, -0.56)D in the right eye and the diopter of -1.25(-2.81, -0.75)D in the left eye, and the maximum preoperative near angle of deviation, with a median angle of 30.00(18.50, 80.00)PD, and the maximum preoperative distant angle of deviation, with a median angle of 35.00(23.75, 80.00)PD. All these differences were statistically significant compared with other two groups(both P<0.05). For the age group from 18 to 45 years old, the median near angle of deviation was 20.00(14.00, 30.00)PD, and the median distant angle of deviation was 25.00(20.00, 35.00)PD, both of which were higher than those in the age group >45 years old(both P<0.05). For the age group >45 years old, the median near angle of deviation after surgery was -4.50(-7.50, 0)PD, and the median distant angle of deviation after surgery was 4.50(0, 9.50)PD, which were smaller than those in other two groups(all P<0.05). The age group >45 years old had the hiughest surgical success rate(100%). The preoperative stereopsis was better in age group >45 years old than the group <18 years old(P<0.05). The postoperative stereopsis of the age group of 18 to 45 years old and the age group >45 years old was better than age group <18 years old(both P<0.05).

CONCLUSION: Surgical patients with AACE are mainly in the age group from 18 to 45 years old. The characteristic of angle of deviation is that distant angle of deviation is greater than near angle of deviation. The patients <18 years old have larger preoperative angles of deviation than adults, while their stereoacuity is worse than adults in the early postoperative period. It is recommended that augmented-dose surgery should be performed in AACE patients who are in the age group of 18 to 45 years old(5-10 PD). A conservative surgery should be designed for hyperopia young children without established binocular vision.
