The morphology and anatomical relationship of periorbital features vary according to age, sex and ethnicity. Standard database regarding periorbital region is available for other ethnic groups. Since there is no data available in the literature, specifically for south Indian ethnic adults, the present study was carried out to determine the normal average values for South Indian ethnic population related to gender.
Anthropometric measurements of both eyes were done on standardized frontal view photograph of 200 South Indian ethnic adults aged 18 to 26 years. Parameters included were palpebral fissure width (PFW), palpebral fissure height (PFH), palpebral fissure inclination (PFI), outercanthal distance (OCD), interpupillary distance (IPD), intercanthal distance (ICD) and comparisons were made between the genders using the independent t test.
Significant sexual dimorphism was noted in the given parameters. Palpebral fissure width (male: 31.08 mm; female: 29.90 mm), palpebral fissure inclination (male: 5.053°; female: 6.102°), outercanthal distance (male: 95.55 mm; female: 92.44 mm) and interpupillary distance (male: 66.72 mm; female: 62.59 mm). The palpebral fissure height (male: 11.30 mm; female: 11.58 mm) and intercanthal distance (male: 34.27 mm; female: 33.41 mm) showed no significant sexual differences.
Statistically significant differences were found between South Indian ethnic males and female in certain key parameters. The present study suggests that ethnicity and gender should be considered in orbital surgery. To individualize the treatment planning and diagnosis, it is important for the surgeons to have knowledge of these local norms.
眶周特征的形态和解剖关系因年龄、性别和种族而异。其他种族有关于眶周区域的标准数据库。由于文献中没有专门针对南印度成年种族人群的数据，因此开展本研究以确定南印度种族人群与性别相关的正常平均值。
对200名年龄在18至26岁的南印度成年种族人群的标准化正面照片进行双眼人体测量。测量参数包括睑裂宽度（PFW）、睑裂高度（PFH）、睑裂倾斜度（PFI）、外眦距（OCD）、瞳孔间距（IPD）、内眦距（ICD），并使用独立t检验对性别之间进行比较。
在所给参数中发现了显著的性别差异。睑裂宽度（男性：31.08毫米；女性：29.90毫米）、睑裂倾斜度（男性：5.053°；女性：6.102°）、外眦距（男性：95.55毫米；女性：92.44毫米）和瞳孔间距（男性：66.72毫米；女性：62.59毫米）。睑裂高度（男性：11.30毫米；女性：11.58毫米）和内眦距（男性：34.27毫米；女性：33.41毫米）未显示出显著的性别差异。
在某些关键参数上，南印度种族男性和女性之间存在统计学上的显著差异。本研究表明，眼眶手术应考虑种族和性别因素。为了使治疗计划和诊断个性化，外科医生了解这些当地标准非常重要。
