OPTICAL COHERENCE TOMOGRAPHY;

RETINAL GANGLION CELL COMPLEX CHANGES ON OPTICAL COHERENCE TOMOGRAPHY AFTER PHACOEMULSIFICATION WITH INTRAOCULAR LENS IMPLANTATION

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.
