Objectives

Narrative objectives1

We recorded flicker ERGs from patients who are going to take cataract surgery. ERGs will be recorded according to the schedule. We are going to examine if we can evaluate postoperative inflammation with ERGs recorded by RETeval system.

Number of participants that the trial has enrolled

32

Results

A transient increase in the amplitude of the flicker ERG was found after lens reconstruction surgery. The increase in amplitude of the flicker ERG was statistically significantly associated with an increase in central retinal thickness, suggesting that the increase in ERG amplitude is likely to represent intraocular inflammation.
