Fluorescein angiography of the iris (IFAG) was performed on 15 patients with a positive cyclopentolate response (IOP elevation ≧ 8 mmHg) in 17 eyes to the cyclopentolate provocative test. The chamber angles were open in all the eyes. Seven of the responder eyes had capsular glaucoma undergoing treatment, six had simple glaucoma, two had pigmentary glaucoma and two suspicion of open‐angle glaucoma. The object was to study with IFAG whether vascular changes can be established in the iris of the responder eyes such as could have a role in the elevation of IOP. All the eyes with capsular glaucoma displayed vascular changes, vaso‐proliferation and fluorescein leakage from the iris vessels. No other vascular changes were seen in the irises of the responder eyes. IFAG revealed no differences in the iris vasculature between responder and non‐responder eyes. A vascular aetiology for the IOP elevation in responders is improbable.
