Recently, central serous chorioretinopathy has been understood to be part of the pachychoroid spectrum. [5] [6] In pachychoroid spectrum disorders, of which CSR represents stage II, the choroid, the highly vascularized layer below the retina, is thickened and congested with increased blood vessel diameter, especially in the deep choroid (the so-called Haller's layer).
Bilateral choroidal metastases are usually due to breast cancer, while unilateral metastasis is due to lung cancer. Choroidal metastases should be differentiated from uveal melanoma , where the latter is a primary tumour arising from the choroid itself.
In all stages, focal choroidal excavation may occur, which probably represents a contraction of the choroid due to scarring processes. [ 7 ] Beyond the spectrum of pachychoroid disorders of the macula, pachychoroid phenotypes have also been described around the optic disc , causing fluid retention in the retina (peripapillary pachychoroid).
Chorioretinitis is an inflammation of the choroid (thin pigmented vascular coat of the eye) and retina of the eye. It is a form of posterior uveitis.Inflammation of these layers can lead to vision-threatening complications.

Serpiginous choroiditis, also known as geographic helicoid peripapillary choroidopathy (GHPC), is a rare, chronic, progressive, and recurrent bilateral inflammatory disease involving the retinal pigment epithelium (RPE), the choriocapillaries, and the choroid. [1]
Polypoidal choroidal vasculopathy (PCV) is an eye disease primarily affecting the choroid. It may cause sudden blurring of vision or a scotoma in the central field of vision . Since Indocyanine green angiography gives better imaging of choroidal structures, it is more preferred in diagnosing PCV.
