macula of retina

[TA]
an oval area of the sensory retina, 3 × 5 mm, temporal to the optic disc corresponding to the posterior pole of the eye; at its center is the central fovea, which contains only retinal cones.

Generally, there is a region with a high density of cones, the area centralis (WILLIS & WILKIE, 1999).
The monofoveal retinas have a central fovea (most birds) or temporal fovea (nocturnal predators, swallows), with or without an area centralis around the fovea (MURPHY, 1993; OROSZ, 2007; RUGGERI et al., 2010).
In vertebrates, three different types of retinal specializations have been identified: fovea, area centralis and visual streak (Walls; Meyer).
Austin Hughes (1977) analysed the topography of the retinal ganglion cells in various species of mammals with particular focus on their density, the density gradient towards the periphery, the presence or not of the visual streak and/or the area centralis, and he concluded that the differences in these parameters were closely related to the animal's lifestyle.
The area centralis is a region of high visual acuity present in a number of species, both herbivores and predators.
Finally, taxonomical classification does not seem to be the parameter that determines either the topography of ganglion cells or the presence of an area centralis. This work demonstrates that the factors which generate greater evolutionary pressure are habitat and lifestyle.
We use the Area Centralis (Volk Optical, Inc.; Mentor, OH) in our clinic.
First, laser titillation was performed using life-size magnification lenses (Mainster Standard lens, 1.04x; and Area Centralis, 1.02x).
Area axialis angusta, area centralis asymmetrica, orbicularis ad latere dorsale et lanceolata ad latere ventrali.
The retina of many vertebrates contains the area centralis, a small central region containing a particularly high concentration of photoreceptors.
