Choroid disease, also known as chorioretinal disease, encompasses a range of conditions affecting the choroid, the vascular layer of the eye. This group of disorders can cause various visual impairments and may lead to permanent vision loss if left untreated. Synonyms for choroid disease include choroidal disorders, chorioretinal disorders, and choroidopathy. These terms are often used interchangeably to describe a wide array of conditions such as choroidal neovascularization, uveitis, angioid streaks, and central serous chorioretinopathy. Proper diagnosis and timely treatment are crucial in managing these disorders, as this can help prevent further deterioration and preserve visual function.
