Purpose

To evaluate any correlation between pterygium laterality and patient handedness.

Methods

Our study represents a retrospective observational study of a series of consecutive pterygium patients recruited from two centres. Each patient was assessed for their handedness which was compared to the laterality of their presenting pterygium. Patients that possessed bilateral disease comparisons between pterygium size and handedness were made. Correlation statistics were performed to compare patient handedness and pterygium location (right or left). For patients possessing bilateral disease only, the pre-surgical differences between lengths and areas of pterygium were calculated and compared.

Results

A total of 219 patients were recruited into our study. 172 patients possessed unilateral disease and in 47 patients, the disease was bilateral. A significant association was identified between handedness and pterygium laterality (p < 0.001). Patients with right-sided pterygia were more likely to be right-handed (OR 2.327) and left-sided presentations who were more likely to be left-handed (OR 5.717). For bilateral presentations, patients were found to have longer (mean increase 3.50 ± 0.47 mm) and larger (mean increase 4.38 ± 0.48 mm²) pterygia in the eye ipsilateral to their dominant hand.

Conclusions

A new insight of handedness as a contributing factor to pterygium laterality is consistent with evidence relating to the asymmetrical development of cortical cataract as well as to theories underlying the geometry of ocular UV exposure. A more complete understanding of factors contributing to ocular insolation may further inform as to improved protective measures and provides further evidence for the role of peripheral light focusing in pterygium pathogenesis.

将其交给翼状：肉：解释翼状lateral肉的偏侧性

目的

评估翼状lateral肉侧向性与患者惯用性之间的任何相关性。

方法

我们的研究代表了从两个中心招募的一系列连续翼状patients肉患者的回顾性观察性研究。对每个患者的惯用性进行评估，并将其与提出翼状ery肉的侧向性进行比较。进行了翼状size肉大小和惯性之间的双侧疾病比较的患者。进行相关统计以比较患者的惯用性和翼状location肉位置（右或左）。仅针对患有双侧疾病的患者，计算并比较翼状length肉的长度和面积之间的术前差异。

结果

本研究共招募了219名患者。172名患者患有单侧疾病，而47名患者则是双侧的。惯性与翼状lateral肉的侧向性之间存在显着相关性（p <0.001）。患有右侧翼状gia肉的患者更有可能是惯用右手的（OR 2.327），而左侧表现则更可能是惯用左手的（OR 5.717）。对于双侧表现，发现患者优势手同侧眼的翼状longer肉更长（平均增加3.50±0.47 mm）和更大（平均增加4.38±0.48 mm ²）。

结论

对翼状lateral肉偏侧性成因的惯用手法的新见解与与皮质性白内障的不对称发展以及眼部紫外线暴露几何学基础有关的证据相一致。对促成眼部日晒的因素的更完整的了解可能进一步有助于改善保护措施，并为周围光聚焦在翼状path肉发病中的作用提供更多证据。
