Anterior segment ischaemia following insertion of a PreserFlo Micro-Shunt with mitomycin-C for uncontrolled open angle glaucoma

To our knowledge, this is the first report of anterior segment ischaemia after PreserFlo Micro-Shunt insertion surgery. Our patient developed anterior chamber (AC) activity and keratic precipitates 1 week after surgery. Five weeks after surgery, examination revealed a shallow AC, a distorted pupil with posterior synechiae and surface iris neovascularisation. Ocular ischaemic syndrome was excluded after performing fundus fluorescein angiography and carotid Doppler ultrasound. The patient responded well to frequent topical steroids and atropine eye drops. 10 weeks postoperatively, the iris neovascularisation had completely regressed with a deep and quiet AC and diffuse filtering bleb with an intraocular pressure of 10 mm Hg without using any pressure-lowering drops. Proposed steps to minimise future incidence of anterior segment ischaemia include avoidance of peri-limbal cautery, controlled use of mitomycin-C application and avoidance of extensive superior fornix dissection.
