To compare the severity and laterality of keratoconus according to allergic rhinitis, scratching and sleeping habits, and manual dexterity.
Objective assessments regarding allergic rhinitis, eye itching, and slee-ping position among patients with keratoconus (diagnosed based on corneal tomography) were conducted. Diagnostic criteria and classification were based on the Amsler-Krumeich classification.
Ocular pruritus was reported by 29 of 34 participants (85.29%). Eighteen participants (62.07%) reported equal scratching of both eyes, six (20.69%) more on the right eye, and five (17.24%) more on the left eye. Comparison of the main sleeping position and the eye with more severe presentation of the disease using Fisher's exact test revealed some correlations (0.567 and 0.568 in the right and left eye, respectively). However, these correlations were not statistically significant.
The association between higher keratometry values and sleeping position appears to be more significant than that reported between keratometry and itching, or manual dexterity.
比较根据变应性鼻炎、搔抓和睡眠习惯以及手灵巧度，圆锥角膜的严重程度和偏侧性。
对圆锥角膜患者（根据角膜断层扫描诊断）进行变应性鼻炎、眼痒和睡眠姿势的客观评估。诊断标准和分类基于 Amsler-Krumeich 分类。
34 名参与者中有 29 名（85.29%）报告有眼部瘙痒。18 名参与者（62.07%）报告双眼搔抓程度相等，6 名（20.69%）右眼搔抓更重，5 名（17.24%）左眼搔抓更重。使用 Fisher 精确检验比较主要睡眠姿势和疾病表现更严重的眼睛，发现存在一些相关性（右眼和左眼分别为 0.567 和 0.568）。然而，这些相关性没有统计学意义。
角膜曲率计值与睡眠姿势之间的关联似乎比角膜曲率计值与瘙痒或手灵巧度之间的关联更显著。
