Abstract:
Objective To investigate the blood supply to sclera near the extrocular rectus end area by fluorescence angiogra -phy in rabbits , so as to provide evidence for the preservation of the sclera flap size in the implantation of artificial eye .Methods Ten healthy adult New Zealand white rabbits were used for the study and underwent evisceration .After excision of the optic nerve and the posterior sclera , sclerotomy was performed , but the sclera flap with four petals remained intact .Sodium fluorescin was injected into the auricular vein for the observation of staining in the deep sclera flap .Results Instantaneous staining range of scleral fluoresce by fluores-cence angiography was within 4 mm to 7 mm near the extraocular rectus muscle end area .Conclusion In the hydroxyapatite orbital im-plantation, the small autoscleral flap with extraocular rectus muscle should be preserved to prevent the implant from exposure .
