To report the ocular features of patients with PD who presented with visual complaints to a tertiary eye care center.
This was a retrospective study carried out between January 2015 and March 2020 at the Neuro-Optometry clinic of a tertiary eye care center in Southern India. All PD patients with ocular complaints examined by the neuro- ophthalmologists were referred to Neuro-Optometry Clinic for detailed evaluation. Patients with other neurodegenerative disorders, brain injury, and other causes of vision loss or extraocular motility disorders were excluded.
A total of 43 patients (7 females, 36 males) between 50 and 86 years of age (mean: 70 ± 8.9 years) with a mean duration of PD of 4.5 ± 4.5 years were studied. Decreased vision associated with reading difficulty (40%) was common in PD patients. In terms of gaze restriction, vertical gaze involvement (35%) was more than horizontal involvement (7%). Convergence insufficiency (CI) was the most common binocular vision dysfunction (30%), followed by CI with oculomotor dysfunction (14%) and vertical gaze palsy (18%). Ground prisms were recommended for 26 patients (61%) and home vision therapy for 5 patients (12%) as corrective measures.
Binocular vision dysfunction is highly prevalent among PD patients. This could potentially contribute to the reading difficulties and double vision encountered by these patients. Assessment of binocular vision and oculomotor parameters thus becomes important to understand and manage the reading difficulties in patients with PD.
报告在一家三级眼科中心因视觉问题就诊的 PD 患者的眼部特征。
这是一项在印度南部一家三级眼科中心的神经眼科诊所进行的回顾性研究，时间为 2015 年 1 月至 2020 年 3 月。所有由神经眼科医生检查的有眼部主诉的 PD 患者均被转介至神经眼视光诊所进行详细评估。排除患有其他神经退行性疾病、脑损伤和其他导致视力丧失或眼球运动障碍的患者。
共纳入 43 名（7 名女性，36 名男性）年龄在 50 至 86 岁之间（平均 70 ± 8.9 岁）的 PD 患者，PD 平均病程为 4.5 ± 4.5 年。阅读困难相关的视力下降（40%）在 PD 患者中较为常见。在凝视受限方面，垂直凝视受累（35%）多于水平受累（7%）。集合不足（CI）是最常见的双眼视功能障碍（30%），其次是伴有眼球运动障碍的 CI（14%）和垂直凝视麻痹（18%）。为 26 名患者（61%）推荐使用基底棱镜，为 5 名患者（12%）推荐家庭视觉治疗作为矫正措施。
PD 患者中双眼视功能障碍的发生率很高。这可能导致这些患者出现阅读困难和复视。因此，评估双眼视和眼球运动参数对于理解和管理 PD 患者的阅读困难非常重要。
