Iridocorneal (ICE) syndrome is a rare ocular disease characterized by abnormal proliferation of corneal endothelial cells, progressive obstruction of irido-corneal angle and atrophy of iris. ICE syndrome progressed slowly, but can cause serious complications such as secondary glaucoma in late stage. Because the etiology of ICE syndrome is not clear, there is still no effective treatment in clinical practice. Previous studies have detected herpes simplex virus (HSV) DNA inside patient's aqueous humor. However, no further explanation for HSV-related etiology of ICE syndrome was established. Besides, construction of animal models using HSV all failed, leaving behind a blank space about how HSV infection finally led to ICE syndrome. By summarizing findings from previous studies, we came up with a hypothesis about etiology of ICE syndrome: HSV infection initiated ICE syndrome by integration of viral genetic material into human genome. Infection of HSV changed activity and morphology of endothelial cells, making them regain the ability of mitosis. Proof of such hypothesis will provide a theoretical foundation for construction of animal models and effective intervention of the disease.
