■评估色素性视网膜炎(RP)患者样品和对照样品中的眼运动性(OM)疾病和斜视。
■在这个横断面回顾性分析中,我们研究了基于Snellen视模的平均年龄为48.74岁,平均视力为7/10的RP患者样本和平均年龄相似的对照患者样本(49岁[男性],47岁[女性])和性别,平均视力为9.9/10,目的是根据年龄评估RP患者的OM改变和斜视之间的相关性,高屈光缺陷,或者双眼视力严重受损。检查遵循了一项测试记忆和最佳矫正视力的方案,以及完整的眼睛检查,角膜反射,覆盖试验,OM,赫斯屏幕,和lang测试。
■在第一次正交光学评估时,45.16%的患者表现为斜视,41.93%的外斜视(25%的间歇性病例),3.22%内斜视,和6.45%的垂直偏差。后来的评估显示25.80%的患者出现斜视,外斜视占19.35%(间歇性9.67%),内斜视占3.22%,垂直偏差在3.22%。对眼睛动力研究的评估显示,下斜肌过度活动和上直肌功能减退占51.6%,和18%的外侧直肌过度反应和内侧直肌功能减退。根据我们的结果,RP患者的OM和斜视改变与年龄或高屈光缺陷无关。因此,运动障碍和斜视归因于男性更容易受到的遗传因素。
■OM障碍的发病率为77.42%,45.16%的患者存在斜视。
UNASSIGNED: To evaluate ocular motility (OM) disorders and
strabismus in a sample of patients with retinitis pigmentosa (RP) and a control sample.
UNASSIGNED: In this cross-sectional retrospective analysis, we studied a sample of RP patients with a mean age of 48.74 years and an average visual acuity of 7/10 based on Snellen optotype and a sample of control patients with similar mean age (49 years [men], 47 years [women]) and sex and an average visual acuity of 9.9/10, with the aim of assessing correlations between alteration of OM and strabismus in RP patients based on age, high refractive defect, or severely impaired binocular vision. The examination followed a protocol of testing for anamnesis and best-corrected visual acuity, as well as a complete eye examination, corneal reflex, cover test, OM, Hess screen, and Lang test.
UNASSIGNED: At the first orthoptic evaluation, 45.16% of patients showed
strabismus, 41.93% exotropia (25% of cases intermittent), 3.22% esotropia, and 6.45% vertical deviation. Later evaluation showed strabismus in 25.80% of patients, exotropia in 19.35% (9.67% intermittent), esotropia in 3.22%, and vertical deviation in 3.22%. Assessment of eye motility study showed 51.6% overaction of the inferior oblique and hypofunction of the superior rectus, and 18% overaction of the lateral rectus and hypofunction of the medial rectus. According to our results, alterations in OM and
strabismus in RP patients are not correlated with age or high refractive defect. Therefore, motility disorders and
strabismus are attributed to a genetic factor to which men are more susceptible.
UNASSIGNED: The incidence of OM disorder was 77.42%, and
strabismus was present in 45.16% of patients.
