Normal Values of Inner Canthal Distance, Interpupillary Distance and Palpebral Fissure Length in Normal Chinese Children in Taiwan
正常台灣新生兒、嬰兒和就學前孩童的眼睛測量
摘要
眼睛測量，包括內眥間距、外眥間距、瞳孔間距和瞼裂長度，在評估先天性畸型是很重要的指標。我們測量了4446個正常的台灣小孩，其中有284個足月新生兒，2742個從1個月到3歲的小孩，和1420個學前孩童的內眥間距、外眥間距、瞳孔間距和瞼裂長度。 我們依年齡算出其保種眼睛測量的平均值的標準差，這些結果可幫助我們評估眼距過寬和其他先天畸型。眼睛測量的結果無性別差異。和之前研究比較，台灣小孩的內眥間距、外眥間距和瞳孔間距較白種人寬，但瞼裂長度欲無差異。我們也發現在同年齡的台灣小孩內眥間距來判定眼距過寬，在台灣小孩是不正確的，因此我們建議眼睛測量的標準應和同樣人種來比較，考慮眼睛的位置對於很多症狀候群的診斷是很有幫助的。

Ocular measurements, including inner canthal distance, outer canthal distance, interpupillary distance, and palpebral fissure length are important in the evaluation of congenital deformities and posttraumatic telecanthus. In this research, 4446 normal Chinese children in Taiwan were enrolled in our study. The sample of 284 full term neonates, 2742 infants and children aged from1 month to 3 years, and 1420 preschool children were measured for inner canthal distance, outer canthal distance, interpupillary distance and palpebral fissure length. We calculated the mean value and standard deviation of the ocular measurements in normal Chinese newborns, infants and preschool children in Taiwan under 5 years. No significant sex differences were observed. Compared with previous studies, inner canthal distance, outer canthal distance and interpupillary distance in Chinese children in Taiwan were wider than those in Caucasian children, but the palpebral fissure length was not significantly different. We also found that inner canthal distance was wider than palpebral fissure length at the same age; therefore it was not correct to diagnose hypertelorism in Chinese children in Taiwan; as if an imaginary third eye could fit between the eyes. Thus, we suggest that measurements should be adjusted with normal standards specific for race. Consideration of the position of eyes is relevant for the diagnosis of a large number of syndromes.
