Occlusion of retinal vasculature first appears in the peripheral retina as “salmon patches”, which represent retinal hemorrhage from superficial blood vessels. These lesions are round or oval in shape and can be elevated or flattened (Figure 1). [7] .

We describe an unusual amblyogenic presentation of non-proliferative sickle cell retinopathy in five-year-old patient with HbSS due to a foveal salmon patch. Numerous vision-threatening complications are possible in SCD, highlighting the need for early vision screening.

Sickle cell retinopathy can be classified as non-proliferative or proliferative. In the non-proliferative form the most common clinical findings are salmon patch hemorrhages, iridescent spots and black sunbursts, which can be observed in the peripheral retina.

Retinal findings of sickle cell disease (SCD) include non-proliferative and proliferative changes. Non-proliferative sickle retinopathy (NPSR) is characterized by arteriolar and capillary occlusion, with accompanying signs such as salmon patch hemorrhages, iridescent spots, and black sunburst lesions.

2016年4月6日 · Sickle cell hemoglobin C (SC) and Sickle cell thalassemia (SThal), are milder systemic forms in the sickle cell disease spectrum, but have a 33% and 14% incidence of proliferative sickle cell retinopathy, respectively. SIGNS Non-proliferative. Salmon patch hemorrhages (intraretinal hemorrhages following peripheral retinal arteriolar occlusion)

2023年7月17日 · Sickle cell retinopathy can be classified as nonproliferative and proliferative. Nonproliferative sickle retinopathy (NPSR) is characterized by the presence of salmon patches, iridescent spots, and black sunbursts. Salmon patch hemorrhages are caused by sudden occlusion and rupture of a medium sized arteriole by sickled red blood cells.

2024年10月25日 · We describe an unusual amblyogenic presentation of non-proliferative sickle cell retinopathy in five-year-old patient with HbSS due to a foveal salmon patch. Numerous vision-threatening complications are possible in SCD, highlighting the need for early vision screening.

As the hemorrhage ages over a period of days to weeks, the color then changes to a salmon hue known as a salmon patch. [5] . They are usually seen adjacent to the retinal arteriole. [6] Bleeding in the deeper layers of the retina leads to the appearance …

2022年3月1日 · The presence of fine, pigmented anterior or vitreous cells and peripheral yellow vitreoretinal lesions in a patient with a past medical or family history of SCD should trigger a high suspicion for salmon-patch associated vitreous hemorrhage and sickle cell retinopathy.
