Conjunctival Cyst with Liesegang Rings: A Case Report and Review of the Literature

Liesegang rings are deposits that most often occur in cystic structures. It is often not recognized due to its rarity and can often lead to confusion with parasitic infections. Reported is a 72-year-old male with a conjunctival cyst with liesegang rings present within the cyst. There have only been 6 previous cases of ocular cysts with liesegang ring formation, 3 eyelid cysts and 3 conjunctival. Parasitic infections are the most often the pathological differential and based on the location of the cyst around the eye the parasites to exclude would be the adult worms of onchocerciasis and dirofilariasis.
