Effect of pupillary dilatation on glaucoma assessments using optical coherence tomography

Entities Mentioned

• Zeiss Stratus OCT

1. Aims:
   To examine the effect of pupillary dilatation on the reliability of retinal nerve fibre layer (RNFL) and optic nerve head (ONH) assessments using Stratus OCT in a glaucoma clinic.
   
   Methods:
   Observational study of 38 patients attending a glaucoma clinic. The "fast optic disc" and "fast RNFL thickness" programs on Stratus OCT were used to measure the RNFL thickness and ONH cup to disc ratio (CDR). Two scans were done before dilatation and two after dilatation with tropicamide 1% drops. The mean values and reproducibility before and after dilatation were compared, along with ...
