To evaluate the effect of strabismus surgery on nystagmus and visual acuity in patients with oculocutaneous albinism.
We conducted a non-concurrent retrospective study of 13 Puerto Rican patients with all types of oculocutaneous albinism who underwent strabismus surgery. Patients underwent genetic linkage analysis to reach a final oculocutaneous albinism classification prior to surgery. Strabismus surgery was modified by under-correction of 0.5 mm in each muscle from the standard Marshall Parks' measurements in all patients.
Six of the 13 patients with oculocutaneous reported an improved best corrected visual acuity after surgery. Two of the 13 patients with oculocutaneous had no nystagmus following strabismus surgery. All patients were orthotropic following surgery.
Strabismus surgical undercorrection may be of benefit in patients with oculocutaneous albinism.
评估斜视手术对眼皮肤白化病患者眼球震颤和视力的影响。
我们对13例接受斜视手术的各类眼皮肤白化病波多黎各患者进行了非同期回顾性研究。患者在手术前接受基因连锁分析以得出最终的眼皮肤白化病分类。在所有患者中，斜视手术均在标准马歇尔·帕克斯测量值的基础上，每条肌肉欠矫0.5毫米。
13例眼皮肤白化病患者中有6例术后最佳矫正视力有所提高。13例眼皮肤白化病患者中有2例在斜视手术后无眼球震颤。所有患者术后均为正位。
斜视手术欠矫可能对眼皮肤白化病患者有益。
