Intravitreal ciliary body neovascularization.

Two patients demonstrated an unusual conformation of intravitreal neovascularization, in which the abnormal blood vessels originated from the ciliary body. One of the patients had recurrent anterior chamber and vitreous hemorrhages. Both patients had undergone thermal ablative therapy of the ciliary body for the control of intraocular pressure. In one patient, fibrovascular tissue emanated directly from old cyclocryotherapy scars on the pars plana. Such neovascularization may represent a previously unrecognized complication of attempts at therapeutic destruction of the ciliary body.
