In simple words: This code refers to the deterioration of the choroid, which is a part of the eye responsible for supplying blood to the retina.

This code represents a degeneration of the choroid, the vascular layer of the eye lying between the retina and the sclera. It includes conditions such as atrophy and sclerosis of the choroid.

Example 1: A 60-year-old patient presents with progressive vision loss. Upon examination, the ophthalmologist finds evidence of choroidal atrophy, confirming a diagnosis of choroidal degeneration., A patient with a history of high myopia is diagnosed with choroidal sclerosis, a type of choroidal degeneration, after experiencing visual disturbances., During a routine eye exam, a patient is found to have patchy areas of choroidal thinning, indicating early-stage choroidal degeneration. Further tests and monitoring are recommended.

Documentation should include a detailed ophthalmological examination report noting the specific type of choroidal degeneration observed (e.g., atrophy, sclerosis), the extent of the degeneration, and its impact on visual function. Supporting diagnostic tests, such as fundus photography or optical coherence tomography (OCT), may also be documented.
