The present study aimed to evaluate the correlation of eye length and bioelectric activity of temporalis, masseter, digastric, and sternocleidomastoid muscles in women with myopia compared to healthy women.
Based on the exclusion and inclusion criteria, 42 women aged 24 years (±2 years) were eligible for the study. Two equally sized groups with myopic ( = 21) and emmetropic healthy subjects ( = 21) were formed. An electromyographic study of the examined muscles was performed in four conditions: at rest, during maximal voluntary clenching in the intercuspal position, during maximal voluntary clenching on dental cotton rollers, and during maximal mouth opening using BioEMG III (BioResearch Associates, Inc. Milwaukee, WI, USA). The IOL Master 500 (Carl Zeiss Meditec, Jena, Germany) was used to examine the eyeball length. Statistical analysis showed significant positive correlations during mouth opening in both groups with open and closed eyes.
A greater number of correlations between the analyzed variables was observed in emmetropic women. In almost all cases, the longer axial eye length was associated with an increase in the bioelectrical activity of the analyzed muscles. Significant correlations were most often observed within the masseter and digastric muscles during the maximum mouth opening and at rest.
There is a relationship between the bioelectrical activity of the masticatory muscles and the axial length of the eyeball on the same side.
本研究旨在评估与健康女性相比，近视女性的眼长与颞肌、咬肌、二腹肌和胸锁乳突肌生物电活动的相关性。
根据排除和纳入标准，42 名年龄在 24 岁（±2 岁）的女性符合研究条件。将 21 名近视和 21 名视力正常的女性分为两组。在四种情况下对检查的肌肉进行肌电图研究：在休息时、在牙间最大随意紧咬时、在最大随意咬牙棉辊时以及在最大张口时使用 BioEMG III（BioResearch Associates，Inc. Milwaukee，WI，USA）。使用 IOL Master 500（Carl Zeiss Meditec，Jena，Germany）检查眼球长度。统计分析显示，两组在睁眼和闭眼最大张口时均存在显著的正相关。
在正视女性中观察到更多分析变量之间的相关性。在几乎所有情况下，眼轴长度越长，分析肌肉的生物电活动就会增加。在最大张口和休息时，通常在咬肌和二腹肌内观察到显著相关性。
同一侧咀嚼肌的生物电活动与眼球的眼轴长度之间存在关系。
