OPTICAL COHERENCE TOMOGRAPHY;

Abstract

ABSTRACT:
 PURPOSE: 
 To study the changes in Ganglion Cell Complex as measured on OCT after
 phacoemulsification with intra ocular lens implantation.
 STUDY DESIGN:
 Quasi experimental study
 PLACE AND DURATION OF STUDY:
 Department of Ophthalmology, Lahore General Hospital, Lahore from 1-3-2017 to 30-4-2018
 MATERIALS AND METHODS:
 Ethical approval of the study was obtained from ‘’Ethical Review Committee’’ of Lahore General
 Hospital, Lahore. Patients presenting to the Eye OPD Lahore General Hospital were assessed for
 inclusion and exclusion criteria. All patients (n=64) diagnosed with cataract requiring surgery
 were included in study. Patients having any coexisting ocular pathology hindering the OCT
 measurement i.e. Corneal opacity, Vitreous hemorrhage, Retinal detachment were excluded
 from study. Retinal Ganglion Cell Complex thickness was measured in Superior, Inferior,
 Supero-Nasal, Supero-Temporal, Infero-Nasal and Infero-Temporal quadrants. Besides that
 Signal Strength on OCT was also documented. Pre-Operatively, Visual acuity was measured and
 OCT performed and the findings were recorded on a designed proforma. Post-Operatively, the
 patients were called for follow-up after one month at which time Visual acuity was again
 measured and OCT performed and findings recorded in the proforma. All the surgeries were
 performed by single surgeon.
 RESULTS: 
 The thickness of Ganglion Cell Complex increased significantly (p<0.001) one month after
 cataract surgery.
 CONCLUSION:
 Cataract surgery does affect the measurement of Retinal Ganglion Cell Complex thickness on
 OCT.
