There are few ways of imaging peripheral retina during an angiogram. One of them is Staurenghi contact lens 230 SLO Retina Lens. Its usefulness in retinal and choroidal disorders has been demonstrated. The lens is used in conjunction with the Heidelberg Retinal Angiogram (HRA) to produce real inverted images of the fundus up to 150° from the posterior pole and even beyond when combined with patient eye movements. We report on the findings of wide field angiography with Staurenghi contact lens in patients with confluent exudates at the posterior pole and peripheral micro vascular abnormalities.
Five eyes of 5 patients with peripheral retinal micro vascular abnormalities and exudates in the posterior pole underwent fundus fluorescein angiography at the HRA with the Staurenghi 230 lens. Two patients also had undergone indocyanine green angiography (ICG-A).
We imaged 4 male and 1 female from 11 to 66 years. Diffuse peripheral micro vascular abnormalities not seen on clinical examinations were identified in all eyes. In one eye, the changes were extensive accompanied by severe peripheral retinal ischemia, yet minimally detectable on funduscopy. Peripheral retinal neovascularisation was seen in two eyes. In 1 eye, the additional use of ICG-A and stereo-imaging helped to outline the presence of pre-retinal neovascularisation in area of retinal fibrosis the origin of which otherwise difficult to interpret. Indirect laser was applied to abnormal retinal areas identified angiographically.
Wide field fluorescein angiography can detect abnormalities of the peripheral retinal vasculature that was extensive and profound than anticipated in patients who have confluent exudates at the posterior pole. Hence, we believe the Staurenghi lens may be useful tool in diagnosis and management of retinal vascular disorder.
