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.
Ophthalmoscopic examination may reveal granular pigmentary changes in the form of bull's-eye maculopathy with a circle of RPE atrophy surrounding the central fovea.
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.
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.
7 cm of diameter of a visual object at a 60-cm viewing distance) correspond to the central fovea.
Given that that the rod-free central fovea encompasses 2.
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.
Macular thickness values in central fovea between treatment and placebo groups were compared by using student's t-test.
At the baseline (on 42nd postoperative day) the mean macular thickness in central fovea was 207.
It is as if the peripheral afterimage is considerably retarded with respect to the central fovea
Within the central fovea
, the carotenoids are most concentrated within the photoreceptor axons of the Henle nerve fibre layer (31).
