Recurrence was defined as fibrovascular tissue extension of more than one mm onto the cornea in the area of previously excised pterygium. Mean follow up period 8±1 month . Recurrence was compared in each group by using ӽ2 testResults:No major postoperative complications occurred during 6-9 months of follow-up . In CLAU group (A)only 5 eyes of recurrence occur(12.5%)after 7 months of follow up .

Corneal endothelial damage following phacoemulsification still one of the major concerns of cataract surgery.

We performed this study to evaluate the changes in corneal endothelium cell density in patients with pterygium.Methods: A cross-sectional, comparative, study was conducted on 20 adults’ patients (total 40 eyes) with unilateral pterygium and a good-quality endothelial cell count. The contralateral eye of each patient served as a control. The endothelial cell density was measured by specular microscope.Results: The majority of patients were males with average age of 45 ±8 years old. Astigmatism difference was of average 1.18 ±1.5. Pterygium length ranged from 2 to 4 mm (mean 2.7 ±0.65mm), width ranged from 2 to 4 mm (mean 2.45 ±0.6mm) and pterygium size ranged from 4 to 12 mm2 (mean, 6.75 ±2.69mm). The Specular microscopy showed no statistically significant difference between eyes with pterygium and controls for endothelial cell density. The correlations between endothelial cell density and pterygium sizes were weak positive not statistically significant (P-value >0.05),Conclusion: In conclusion, this comparative study showed that pterygium was associated with a decrease in corneal ECD but with statistical insignificant difference.}, keywords = {Pterygium,endothelium cell density,Comparative study}, url = {https://niles.journals.ekb.eg/article_91228.html}, eprint = {https://niles.journals.ekb.eg/article_91228_88509c8b6700ff796c9571e05e8da6b2.pdf} } @article { author = {Mahmoud, Hany}, title = {The impact of COVID-19 on ocular Trauma}, journal = {NILES journal for Geriatric and Gerontology}, volume = {3}, number = {Geriatric ophthalmology}, pages = {29-33}, year = {2020}, publisher = {Beni-Suef University, National Institute of Longevity Elderly Sciences}, issn = {2636-3224}, eissn = {2636-3232}, doi = {10.21608/niles.2020.38878.1034}, abstract = {Abstract:Introduction: COVID-19 emerged as global health catastrophe which affected all activities.
