先天性小眼症
先天性小眼症(眼裂狭小症):指眼裂宽度较正常缩小,为具有遗传性的睑部先天性异常,一般由于眼脸皮肤愈着,韧带紧张所致,多同时发生左右两侧。
先天性小眼症可合并存在下列情况:
1、侏儒症;
2、小眼球或无眼球;
3、上睑下垂及内毗赘皮;
4、内眦向颞侧移位;
5、半面萎缩。
其中以先天性小眼症合并内眦赘皮及上睑下垂最为多见。
先天性小眼畸形对儿童面部的外观与生活有很大影响,其视力功能也下降。这种孩子出生后,两眼间距宽,眼裂小,有严重的内眦赘皮,鼻梁平塌,面容无神,可误诊为内斜视。逐渐长大后,由于鼻骨发育提高,情况可能有所改善。因此不宜过早进行整形手术,一般在学龄前手术较为适宜。单纯的小眼症可以同时进行矫正外眦及或开大眼裂,如合并有上睑下垂者应于6-12个月后行上睑下垂矫正术。
对于有明显的内眦间距增宽,严重的内眦赘皮和上睑下垂的小眼裂综合征者,联合手术矫正是当前效果最好的手术方法。它不仅矫正内眦赘皮,而且还可以矫正内眦间距宽度。其缺点是手术后疤痕需在一年后趋向不明显。

Congenital microophthalmia
Congenital microphthalmia syndrome (narrow palpebral fissure syndrome) : refers to the narrow width of palpebral fissure than normal, with hereditary eyelid congenital anomaly, the more general because of eyelid skin, ligament strain, multiple simultaneous left and right sides.
Congenital microophthalmia can be combined in the following situations:
1. Dwarfism;
2. Small eyeball or no eyeball;
3. Ptosis of upper eyelid and inner pepe;
4. The medial canthus shifts to the temporal side;
5. Half face atrophy.
Among them, congenital eye disease combined with inner canthus and ptosis are the most common.
The appearance and life of children's face have a great influence on the appearance and life of children. After the birth of the child, the two eyes are wide, the eyes are small, and there is a serious inner canthus, the bridge of the nose is flat, the face is not god, but the misdiagnosis is the internal strabismus. Gradually, as the nasal bone develops, the situation may improve. Therefore, it is not appropriate to have plastic surgery too early, which is generally appropriate in preschool. Simple eye disease can be performed simultaneously to correct the canthus or open fissure, such as the combination of the upper eyelid ptosis should be in 6-12 months after the ptosis correction.
In the case of the obvious medial canthal spacing, severe internal canthus and ptosis of the upper eyelid, combined surgical correction is the best operative method. It not only corrects the inner canthus, but also corrects the width of the inner canthus. The disadvantage is that the post-operative scar should not be obvious after a year.
