To study the possible correlation between pupillary diameter before and after dilation with intraocular pressure, lens stability and glaucomatous damage (represented by optic disc changes using cup to disc ratio and OCT changes in retinal nerve fiber layer and ganglion cell complex) in each eye of the same patient with PEX.
All patients with pseudoexfoliation syndrome.
previous ocular surgery or ocular trauma affecting the pupil. Any systemic or neurologic disease affecting the pupil

optical coherence tomography
DeviceOptical coherence tomography (OCT) is a non-invasive imaging test . It uses light waves to take cross-section pictures of the retina . With OCT, the ophthalmologist can see each of the retina's distinctive layers, and so we can use it to study the changes in pseudoexfoliation syndrome.
To study the possible correlation between pupillary diameter before and after dilation with intraocular pressure, lens stability and glaucomatous damage
in each eye of the same patient with PEX we study the correlation between the pupillary size before and after dilation with intraocular pressure, lens stability and glaucomatous damage represented by optic disc changes (cup to disc ratio) and OCT changes (RNFL and GCC).
