The oval pupil.
The dynamics of pupillary dilation induced by Phenylephrine 10% and Cyclopentolate 1% have been examined by flash photography. A correlation between anterior chamber depth and the pupil shape on dilation with Phenylephrine Hydrochloride 10% is described. It is postulated that these pupillary dilation dynamics support a sympathetic abnormality as a trigger for acute primary angle closure glaucoma.
