Study Notes
Retinal Layers and Structure
- The retinal pigmented epithelium (RPE) forms the outermost layer of the retina.
- The RPE is more adherent to the choroid than the rest of the retinal tissue.
RPE Characteristics
- The RPE is pigmented in the tapetal fundus and can be seen clinically.
- The RPE helps to phagocytose the dead photoreceptors.
Retinal Layers
- The inner sensory retina contains more than nine layers.
- The sensory retina or neuroretina is composed of layers 2 through 10 and is responsible for processing the neuronal signal or visual sensation.
Retinal Regions
- The optic retina extends from the optic disc to the ora ciliaris retinae.
Fundus Appearance
- The tigroid fundus refers to the visibility of the underlying choroid and sclera in the non-tapetal area where there is no pigment in the RPE.
Retinal Thickness
- The retinal thickness is primarily influenced by the vascularity rather than the dominant type of photoreceptor.
