Clinical Trial Summary

To study possible correlation between the size of the pupil in both room light and after dilation between both eyes in bilateral pseudoexfoliation with Intraocular pressure, lens clarity and stability, Optic disc , Visual changes and glaucoma changes by optical coherence tomography

Description:

For each patient. Full preoperative ophthalmological assessment will be done using slit lamp , size of the pupil in regular room light (usually around 2000 Lux) and post dilation with tropicamide 1%. baseline IOP measurement using Goldmann applanation tonometer, UCDVA (Uncorrected Distance Visual Acuity)and CDVA (Corrected Distance visual acuity), lens opacification or clarity, stability or subluxation. corneal endothelial cell count. Fundus examination using 90 D or 78D lenses, Humphrey visual field (24-2) analysis and optical coherence tomography on retinal nerve fiber layer (RNFL) and ganglion cell complex.(GCC)
