Diurnal raptors, which have eyes arranged laterally, have a central fovea and a temporal fovea (Inzunza et al., 1991; Jones et al.).
Fundus autofluorescence (FAF) showed well-defined areas of atrophy OU and sparing of the central fovea in the right eye (Figures 1(c) and 1(d)).
Elongation of axial length may explain the phenomenon of greater choroidal thinning in the central fovea versus thinning found in the regions inferior and superior to the central fovea.
In this protocol, manual measurement of the outer retinal layer thickness (OLT) was performed at a point in the central fovea from internal limiting membrane (ILM) to the apex of retinal pigmented epithelium (RPE) by an ophtalmologist who was blinded to the primary diagnosis and drug consumption properties of the subjects.
[10] If there is edema in the macula or the central fovea, where it threatens central vision, one must first identify the leaking microvascular lesions by injecting sodium fluorescein angiography intravenously and photographing retinal vessels by fundus camera.
Due to the increased length of outer cone segments in central fovea, this line is slightly elevated in foveal region.
[19] final visual acuity negatively correlated with height of the detachment at the central fovea and distance from the central fovea to the nearest undetached retina.
Although there are some discrepancies among authors regarding the different substructures within the fovea, an accepted division of the whole foveal area is: central fovea, parafovea, and perifovea.
Fundus autofluorescence revealed hyperautofluorescent spots were seen in the central fovea and superonasal to the fovea (Figure 3).
In addition, the eyes were divided into group 1 (LC passed the central fovea) and group 2 (no LC passed the central fovea).
The central fovea appears as an isolated, pigmented island, surrounded by an annulus of atrophied, depigmented retinal pigment epithelium, itself encompassed by a hyperpigmented region.
The best quality macular thickness maps (signal strength five or more) at those visits were analyzed to produce macular thickness map, consisting of thickness values in central fovea. Data were entered into a Microsoft Excel spreadsheet and analyzed using spss (version 12.0, SPSS, Inc., Chicago, IL, USA).
