摘要

極高度近視在西方國家甚為少見，而在近視王國台灣偶而可見，我們收集9例20屈光度以上近視共14隻眼球分析其年齡、職業、家族史、近視進展、檢查其眼底、眼壓，並能每個眼球之屈光組成份(component)加以分析，發現大部分有家族傾向，至於年齡、職業並無好發傾向，每一近視眼球其眼底均有變化，而其屈光組成份除眼軸長比正視眼高出許多外，其餘前房深度、角膜曲率半徑、晶體厚度及眼壓均與正視眼差異不大。

Excessive myopia is very rarely seen in the western countries. However, it can be seen in the Oriental people. We have collected 14. eyes of 9 patient of excessive myopia of 20 or over 20 diopters. The parameters we studied included age, sex, blood type, occupation, family history, the developing course of the myopia and the refractive components. We found that 5 of 9 patients presented with family history. There were high myopic change of the fundi in all the 14 eyes, this finding gave us the impression that all 14 eyes were pathologic myopia. The average axial length of these eyes was much longer than that of the emmetropic eyes. The intraocular pressure, anterior chamber depth, corneal curvature and the lens thickness were no significant difference with the emmetropic eye.
