BACKGROUND Evaluation of the vasculature and blood flow in the fundus is limited by the small field of view of conventional fundus cameras. We sought to develop an easy method to image wide areas of the fundus. METHODS Wide-angle contact fundus lenses with antireflective coatings in the infrared range were placed on the eye and indocyanine green angiography was done on the fundus through the contact lenses. More than 50 patients with varying fundus pathology have been examined. RESULTS The angular field of view using this method can reach 160 degrees. Obtaining angiograms where the field of view extended anterior to the ora serrata was simplified, and studying the choroidal vasculature in detail was possible. In addition, imaging of entities such as peripheral choroidal neovascularization and choroidal tumors was enhanced with the present technique as compared with conventional techniques. CONCLUSIONS Angiography through wide-angle fundus lenses is an easy and inexpensive method of visualizing large areas of the fundus. This technique may help improve our ability to image the angioarchitecture, hemodynamics, and pathologic changes in the retina and choroid.

D002830 Choroid Neoplasms Tumors of the choroid; most common intraocular tumors are malignant melanomas of the choroid. These usually occur after puberty and increase in incidence with advancing age. Most malignant melanomas of the uveal tract develop from benign melanomas (nevi).
