Advancing a Joint Classification and a Pilot Study in Patients Suffering from Nonocclusive Hydrocephalus 27 36 EN Carlo Aleci The Gradenigo Hospital, Department of Ophthalmology, Turin, Italy Carlo Mannone Nicoletta Rebaudengo NOVN2015116 10.12691/novn-1-1-6 2015 01 30 2015 04 27 2015 05 03 Similarity in embryological development, anatomical and structural organization as well as chemical physical properties of organs and apparatus makes them common targets for specific pathological events. Such multi-involvement could well be the case of the cerebrospinal and aqueous circulatory systems, respectively in the brain ventricles and in the anterior and posterior chamber of the eye. After having described the resemblances in secretion, circulation, absorption and composition of the ventricular cerebrospinal fluid and of the ocular aqueous humor, a joint classification of their pathological involvement, namely hydrocephalus and glaucoma, is advanced. Finally, based on our preliminary results, morpho-functional alterations of the ventricular fluid dynamics leading to communicant hydrocephalus is suggested to affect to a certain extent the ocular hydrodynamics as well, predisposing the eye to ocular hypertension.
