简要总结
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
详细描述
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)

结局指标
主要结局
correlation between pupil size and severity of Pseudoexfoliation
时间窗: 2-3 months
in each eye of the same patient we study correlation between pupil size with ntraocular pressure, lens status, corneal endothelial count and glaucomatous damage represented by (optic disc changes (cup to disc ratio) and OCT changes (RNFL and GCC)
