AbstractBackground:Glaucoma is a disease known since the Hippocrates time. This term indicates a number of neurodegenerative diseases having in common a progressive optical atrophy resulting from the apoptosis of retinal ganglion cells, axon atrophy, and degeneration extending to the visual areas of the brain cortex, finally leading to the characteristic optical-cup neuropathy and to irreversible visual loss.
Aims & Objectives:The aim of this study is to determinechanges in corneal curvature, axial length and IOP reduction after glaucoma filtration surgery.
Material and Methods:The present study was conducted in the department of Ophthalmology, Ananta Institute of Medical Science & Research Centre Rajsamand, Rajasthan during the period of 1 year from January 2019 to January 2020.25 diagnosed cases of glaucoma who were undergoing glaucoma surgery (trabeculectomy) of either sex, age were included in the study.
Results:TheMean values of keratometry (D) at pre-operative, 1 week, 4 week and 3 months are 1.28±0.744, 4.097±2.915,3.484±1.662 and 2.150±1.051 respectively while the mean value of axial length atpre-operative, 1 week, 4 week and 3 months are 22.537±0.786,22.390±0.783, 22.356±0.782 and 22.402±0.716.
Conclusion: Trabeculectomy is the most common surgical procedure for glaucoma management which may significantly influence ocular biometry. Change in keratometry and axial length can be significant enough to affect visual acuity and the accuracy of IOL power calculation.
