I. On the anatomy of the fovea centralis of the human retina

Abstract 1. The Fovea centralis is a minute circular pit in the inner surface of the retina, made by the radial divergence of the cone-fibres from a central point, by the thinning and the outward curving of the inner retinal layers towards this point, and by the peripheral location of the outer granules belonging to the central cones. 2. The inner surface of the retina declines in a rapid uniform curve from the edge to the centre of the fovea, and very gradually from the edge towards the ora retinse; so that the edge of the fovea is the most raised part in the macula lutea, where the retina is thickest, and the centre of the fovea the most depressed part in the macula, where the retina is thinnest.
