Suprachoroidal Space

The suprachoroidal space (spatium suprachorioideale, SSP) is the intercellular space between the layers of the choroid membranes, which is located between the posterior and anterior choroid membranes. It plays an important role in the circulation of blood and lymph, as well as in the metabolism between the choroid membranes and other tissues and organs.

Suprachoroidal spaces can be either expanded or narrowed. They can be associated with various diseases such as chorioretinitis, Cushing's syndrome, hypothyroidism, diabetes, nephrotic syndrome, etc.

With chorioretinitis, the SSP may be dilated and contain an increased amount of fluid. This can lead to deterioration of vision and decreased visual acuity, as well as the development of other complications such as retinal detachment.

Treatment of chorioretinal diseases associated with SSP dilatation may include retinal laser photocoagulation, intravitreal injections, and other treatments.

In general, the suprachoroidal spaces play an important role in the functioning of the choroid membrane and other tissues and organs, so their condition should be monitored and treated if necessary.
