Iris and its relevance to angle closure disease: a review

British Journal of Ophthalmology, 2020
Glaucoma is a leading cause of irreversible visual impairment, and primary angle closure glaucoma (PACG) affects Asians disproportionately. Whereas advances in ocular imaging have identified several anatomical risk factors, our ability to predict PACG still requires considerable improvement. The iris plays a crucial role in the pathophysiology of angle

Parasympathetic denervation of the iris in Chagas' disease

Clinical Autonomic Research, 1992
The parasympathetic innervation of the iris along with cardiovascular reflexes involving parasympathetic and sympathetic function were studied in 45 patients with Chagas's disease and in 36 controls. The autonomic features in Chagas' disease included 15 with cardiomyopathy, three with megaoesophagus and five with megacolon.
