Bilateral ectopic pupil icd 1012/10/2023 On the other hand, congenital ectropion, is thought to be the result of failure of regression of a primordial endothelium in the anterior chamber. This fibrovascular membrane (or neovascularization of the iris) can be from multiple sources with the most common etiologies being proliferative diabetic retinopathy and central retinal vein occlusion, or less commonly inflammatory, neoplastic, or ischemic processes involving the iris. As this membrane contracts, the posterior pigmented iris epithelium is pulled around to the anterior iris surface. Acquired ectropion is more common than congenital, and is associated with tractional forces secondary to a fibrovascular membrane spreading across the anterior surface of the iris. The differences are based primarily on the etiology of the ectropion. H21.89 Other specified disorders of iris and ciliary bodyĮctropion uveae can be divided into two main categories: acquired and congenital. We recommend the following codes as appropriate. Ĭongenital ectropion uveae (CEU) does not have a specific code as per the International Classification of Diseases (ICD) nomenclature. The first authors to accurately describe congenital ectropion were Wicherkiewicz in 1891 and Spiro in 1896. The term congenital ectropion was first introduced by Colsman in 1869, but it was later discovered that his description was actually iris flocculi.
