A Statistical Observation of Causes of Enucleation

The authors analysed statistically 169 cases of enucleation among 132, 168 outpatients, 3, 786 inpatients, 4,640 eye operations who visited to the National Medical Center for 16 years duration from Jan. 1962 to Dec. 1977. 1) The incidence of enucleation is 0.13% of all eye outpatients. 2) The male and female ratio is 2.2:1. 3) The frequency of enucleation is as follows, malignant tumor, retinoblastoma(the majority) 42 cases(24.9%), corneal disease, staphyloma(the majority) 38 cases(22.5%), glaucoma 30 cases(17.8%), panophthalmitis 23 cases(l3.6%), trauma 19 cases(11.2%) and phthisis bulbi 17 cases(10.0%).
