Abstract:
Fibrovascular ingrowth of 55 cases of intraorbital hydroxyapatite sphere was evaluated by magnetic resonance imaging about 5 months postoperatively at the Department of Ophthalmology, Yeungnam University College of Medicine from April 1993 through May 1998. Of them, evisceration was performed in 35 cases; enucleation in 14 cases, and secondary implantation in 6 cases. Fibrovascularization was classified into 4 groups by width and strength of enhancement, Grade 3-4 and 5 cases showed delayed fibrovascularization, Grade 1. Driling for peg could be performed within 1 month in the cases with Grade 3 fibrovasculariztion. In cases of delayed fibrovascularizated Grade 1 or Grade 2, driling should be performed after confirmation of complete fibrovascular ingrowth by repeated magnetic resonance imaging.
