Abortive neovascular outgrowths discovered during vitrectomy for diabetic vitreous haemorrhage.
Abortive neovascular outgrowths from the retina were identified in 13 out of 34 eyes (38%) undergoing vitrectomy for diabetic vitreous haemorrhage. Postoperatively, fluorescein angiography of the lesions demonstrated a characteristic "smoke-stack" pattern of dye leakage. Each outgrowth appears to represent a focal variant of preretinal neovascularisation complicating retinal capillary non-perfusion and inner retinal ischaemia, their distinctive features being determined primarily by the absence of a cortical vitreous scaffold on the retinal surface at the time of vasoproliferation.
