Keeping the head in a neutral position is requisite for glasses/lenses/head-up designs, the suitability of oculo-plastic surgery and for the grading the eye shift. Anatomically incompatible glasses are one of the common problems affecting accommodation, reducing comfort and disturbing by causing symptoms such as dizziness and nausea. The oculo-palpebral measurements act as a key determinant in symmetrical facial attractiveness. This study aims to investigate the most effective oculo-palpebral landmarks, head-neutral as the ideal position, taking into account of individual anatomical differences of these patients.
100 females and 100 males aged between 18 and 20 years were photographed. Digital photogrammetric measurements were made with the ImageJ program. Interpupillary and interhelical distances, besides bilateral palpebral fissure length and height, and iris diameter were calculated on front-facing photographs.
Mean interpupillary distance was measured wider in males than in females. The mean length of palpebral fissure was 31 mm; palpebral fissure height was 10 mm. These figures were valid in both eyes and gender. The interhelical distance was calculated as the mean and was measured longer in men. Since the measurement values were the same in both sexes and on both sides, they were determined as important landmarks for controlling the head-neutral position, evaluating whether there was a deviation in the eye, and measuring the numerical value when detected.
It is essential to check the side-symmetry of the patient's palpebral fissure height, palpebral fissure length, diameter of iris and corneal depth during oculo-plastic invention and artificial design.
保持头部处于中立位置对于眼镜/镜片/抬头设计、眼整形手术的适用性以及评估眼球移位非常重要。解剖结构不兼容的眼镜是影响调节功能的常见问题之一，会降低舒适度并引起头晕和恶心等症状。眼-睑测量是对称面部吸引力的关键决定因素。本研究旨在探讨最有效的眼-睑标志点，将头部中立作为理想位置，同时考虑到这些患者的个体解剖差异。
对 100 名年龄在 18 至 20 岁之间的女性和 100 名男性进行拍照。使用 ImageJ 程序进行数字摄影测量。在正视照片上计算瞳孔间距离和虹膜间距离，以及双侧睑裂长度和高度、虹膜直径。
男性的平均瞳孔间距离比女性宽。睑裂长度的平均值为 31mm；睑裂高度为 10mm。这些数值在双眼和性别中均有效。虹膜间距离为平均值，男性的测量值较长。由于男女之间和两侧的测量值相同，因此它们被确定为控制头部中立位置、评估眼睛是否有偏差以及测量检测到的数值的重要标志点。
在眼整形发明和人工设计过程中，检查患者睑裂高度、睑裂长度、虹膜直径和角膜深度的侧面对称性非常重要。
