Objective:
To assess patient demographics, clinical indications, and pathologic causes of surgically removed eyes over a decade in Ontario (Canada) and to identify areas of ocular disease management needing more attention.
Design:
Retrospective cross-sectional study.
Participants:
The surgically removed eyes of 713 consecutive mainly adult patients from 2004 to 2013.
Methods:
Demographic, clinical, and pathologic data were collected on all eyes received by the University of Toronto Ophthalmic Pathology Laboratory from 2004 to 2013.
Results:
Of the 713 eyes removed, enucleations accounted for 60% of cases, eviscerations for 39% of cases, and exenteration for 1% of cases. The most common clinical indications for surgical eye removal were blind painful eye (37%), neoplasm (35%), and trauma (6%). The leading pathologic causes of eye removal were neoplasm (36%), glaucoma (21%), infection or inflammation (17%), and trauma (16%). Glaucoma-related findings were the most common pathologic findings observed (38%), regardless of the primary cause.
Conclusions:
A blind painful eye and neoplasms were the most commonly documented indications prior to removal of the eye. Common pathologies included glaucoma, neoplasms, infection/inflammation, and trauma. However, regardless of the primary cause, glaucoma-related pathologies were the most common pathologic findings. Refractory eye disease and pain continue to be important reasons for removal of eyes among patients in Ontario. More effective and targeted management strategies are needed to reduce the need for this radical eye surgery of last resort.
