Purpose:
To investigate the pathogenesis of suprachoroidal and supraciliary hemorrhage that might have been induced during enucleation.
Methods:
A histopathological examination of 392 enucleated eyeballs was carried out and 8 eyeballs with suprachoroidal and supraciliary hemorrhage were selected for further clinicopathological examination.
Results:
Among 14 eyeballs with severe acute intraocular inflammation, 7 eyeballs with suprachoroidal and supraciliary hemorrhage were found and one other such eyeball was seen among 53 with neovascular glaucoma. Among these 8, there was one case of prolapse of intraocular tissue with severe hemorrhage into the suprachoroidal and supraciliary spaces; 4 cases of severe hemorrhage into the suprachoroidal and supraciliary spaces without prolapse of intraocular tissue; and 3 cases of mild hemorrhage into the suprachoroidal or supraciliary spaces.
Conclusions:
In the eyeballs with severe acute intraocular inflammation, intraocular pressure was elevated and the blood vessels were weakened by inflammatory cell infiltration. During enucleation external forces affected the blood vessel wall of the ciliary arteries and vortex veins, and the breakdown of vessel walls might have been the cause of the suprachoroidal and supraciliary hemorrhage.
