Abstract

Objective: To analyze the etiology and related factors of destructive ophthalmic surgeries, including enucleation of the eyeball, evisceration and orbital exenteration. Methods: The medical records of 676 patients (676 eyes) who underwent ophthalmic destructive procedures were reviewed retrospectively from July 2011 to September 2017 at the Eye Hospital, Wenzhou Medical University. There were 437 males and 239 females; aged from 7 months to 90 years old, and the causes of the operation and its distribution were analyzed. Results: In 676 cases, 230 cases were enucleation, accounting for 34.0%; 426 cases were evisceration, accounting for 63.0%; 20 cases were orbital exenteration, accounting for 3.0%. There were 31 children younger than 12 years old, among them, 18 cases of enucleation and 2 cases of orbital exenteration due to retinoblastoma. There were 430 cases of adults aged from 19 to 60 years old. Ocular trauma related diseases were the first cause, about 219 cases. There were 191 elderly patients over the age of 60. Keratitis and cornea related diseases (57 cases) and glaucoma (51 cases) were the main causes. And in older patients, removal of orbital contents was a common cause of eyelid malignancy. Conclusions: In different age groups, the main causes of unilateral blindness are different. Therefore, the emphases of the promotion of preventive health care knowledges and treatment priorities should be different among different age groups. Key words: enucleation; evisceration; orbital exenteration; ocular trauma; retinoblastoma; eyelid malignant tumor
