A method of examination of the extreme fundus periphery has been devised by one of us (C. L. S.) and described previously.22 The instrument used is a binocular indirect ophthalmoscope mounted on a headband. With this ophthalmoscope* the extreme fundus periphery may be observed from the posterior pole to the posterior border of the ciliary processes, provided the sclera is indented with a scleral depressor.†
This method of examination is useful not only for the diagnosis and surgical treatment of retinal detachment but also for the study of changes observed in the fundus periphery in other conditions, for instance, uveitis, macular degeneration, angiospastic retinitis, recurrent vitreous hemorrhages, and choroidal or retinal tumors. The alterations detected are important to complete the clinical picture of the diseases concerned and to improve understanding of their pathogenesis. Because of the clinical importance of a careful examination of the fundus periphery, every patient seen
