Conjunctival Lymphangiectasia Imaged with Anterior Segment OCT

Conjunctival lymphangiectasia is an ocular surface disorder resulting from dilated lymphatic vessels of the conjunctiva [1]. It is commonly found in routine eye examination and exists in two different forms: as diffuse dilated vessels, known as chemosis, and as focally dilated vessels. The latter can occur as isolated cysts or as a series of adjacent cysts, also described as a “string of pearls”. The ectatic lymphatic vessels differ from normal lymphatic vessels by an increased diameter and a frequent occurrence of an edematous lamina propria, which is presumably due to leaking of the dilated channels. Histopathological examination reveals thin vessel walls with flattened endothelial cells [1]. We report here on the use of anterior segment optical coherence tomography (AS-OCT) in combination with IR imaging as a method to display asymptomatic lymphangiectasia of the conjunctiva.
