Rainbow Fovea. Cone photoreceptors of the fovea -located in the central part of the retina- are responsible for daylight and color vision. Cones are also essential for high acuity vision, needed to perform tasks that require precision such as reading, or recognizing faces. The image was acquired with a confocal microscope from a non-human primate retinal flatmount, after immunostainings.

Inside the compound eye of a fiddler crab: This electron micrograph shows a cross-section through one of the many thousand elongated ommatidia (eye units). Seven retinula cells contribute microvillus projections to a central photosensitive rhabdom at perpendicular angles. This allows the crab to discriminate between horizontally and vertically polarized light.

Clustered vision. Vitality staining of living retina of guinea pig. Top view onto the ganglien cell layer and nerve fibers shows a clustered organization of Müller glial cells' endfeet (red), accurately separated from each other by fine lipid membranes (green) and surrounding ganglien cells (black circles)

This fundus fluorescein angiogram of a patient with Choroideremia uses the nine field view which has then been merged together to create a wider view giving the clinician a better understanding of the geography of the remaining retina.

Gyrate atrophy (GA). A 28 years old female, presented with history of progressive night blindness, Best corrected visual acuity (BCVA) was 6/120 in both eyes. Slit-lamp examination displayed bilateral posterior subcapsular cataracts, and fundoscopy revealed bilateral sharply demarcated circular areas of chorioretinal atrophy involving the mid-periphery (A). The posterior pole was relatively spared of these lesions but did have a large round atrophic lesion at the temporal side of the right’s eye macula. In addition, there were elevated pinkish-yellow lesions with occasional tiny spots of calcification over both optic discs (B). Their clinical and ultrasonography (US) appearance were consistent with optic nerve astrocytic hamartoma (rarely associated with GA). Serum ornithine levels were markedly elevated (697 μmol/l, reference range 19–81 μmol/l). Sequencing the OAT gene identified a previously reported single base pair (bp) deletion of cytosine at position 159 of the cDNA
