Final answer:
Ectopic lentis is associated with various medical conditions, including idiopathic juxtafoveal retinal telangiectasia, systemic diseases such as nephrosis and atherosclerosis, and infectious diseases like Acanthamoeba keratitis and Loiasis.
Step-by-step explanation:
Ectopic lentis refers to the displacement or malposition of the crystalline lens of the eye. Several conditions can be associated with ectopic lentis, presenting in various medical diseases and health issues. One such condition is idiopathic juxtafoveal retinal telangiectasia, involving dilated and twisted blood vessels in the retina. Disorders of embryo development can also be related to ectopic conditions, such as tubal or ovarian ectopic pregnancies, although these are not directly related to ectopic lentis.
Other health complications linked with ectopic lentis include systemic diseases like nephrosis, myxoedema, abetalipoproteinemia (acanthocytosis), xanthomatosis, tuberculous, atherosclerosis, hyperthyroidism, hypertension, infective hepatitis, and severe diabetes mellitus. Furthermore, infectious diseases such as Acanthamoeba keratitis, a parasitic infection commonly associated with contact lens use, and Loiasis, or eye worm, a disease endemic to Africa caused by parasitic worms, can also manifest with ectopic lentis among other eye-related symptoms.
