Inferior retinal dialysis with a localized area of long-standing retinal de­tachment and demarcation line (upper left). There is total atrophy of the photoreceptor cell layer (upper right). The demarcation line (lower views) is an area of RPE hypertro­phy and hyperplasia with nodular basement membrane production and retinal adhe­sion.

Condition/keywords: photoreceptor cell, retinal dialysis, retinal pigment epithelium (RPE) hypertrophy

Peripheral punched-out lesion from choroidal infarction. The lesion is surrounded by hypertrophic RPE which gives the lesion a dark halo. There is loss of the choriocapillaris, RPE, and outer retinal layers with no reparative proliferation.

Diffuse peripheral RPE hypertrophy. There is a band of pigmentation just posterior to the ora serrata (upper left) where the RPE is darker and contains larger, spherical pigment granules(lower right). The junction (arrow) between normal (left) and hypertrophic (right) pigment epithelium is illustrated in the lower left view. A few areas of paving-stone degeneration are present at the equator (upper left).

Condition/keywords: ora serrata, retinal pigment epithelium (RPE) hypertrophy

Two localized areas of RPE hypertrophy. The RPE has melanin granules that are large and spherical (lower views.)

Traumatic retinopathy with retinal pigment epithelial hypertrophy, hy­perplasia, and migration into the retina in a perivascular location, giving a spiculate appearance which is similar to that seen in retinitis pigmentosa. This eye had additional features of trauma.

40-year-old female, asymptomatic, without history of trauma. VA 20/20. No comorbilities. No ophthalmologic surgeries. It was a incidental finding. It can be observed a large RPE hypertrophy at the nasal retinal zone that borders the optic nerve with a line of demarcation that corresponds to a self applied retinal detachment.
