The pachychoroid spectrum is a new entity grouping pathologies with common choroidal features. First described in 2013 by American ophthalmologist Bailey Freund and his team [1]. It is defined by a diffuse or focal increase in choroidal thickness with dilatation of choroidal vessels adjacent to Bruch's membrane, associated with retinal pigment epithelial dysfunction, loss of the choriocapillaris and thinning of Sattler's layer [1, 2]. At present, the pachychoroid spectrum includes well-known pathologies such as central serous chorioretinitis (CSCR) and polypoidal choroidal vasculopathy (PCV), as well as pathologies of more recent description such as epitheliopathy or type 1 neovessels secondary to pachychoroid, pachydrusen, choroidal excavation and peripapillary pachychoroid. The morphological changes of the lens which is a cataract can be unilateral or bilateral and occur symmetrically or not over variable durations. A cataract is said to be mature when the opacification occupies the entire lens, it induces a complete loss of vision. It makes the visualization of the fundus reflection impossible, which explains the impossibility of visualizing hemorrhages and other lesions of the eye with the possibility of concealing a pachychoroid spectrum during the ocular examination in patients. The aim of our study is to describe the symptomatology and therapeutic approach of SPC.
