TitreSubfoveal choroidal thickness measured by OCT EDI (Enhanced Depth Imaging) was not found to be altered by the administration of tropicamide and phenylephrine eyedrops
Abstract Nr.1064
ButTo investigate if administration of commonly used mydriatic eyedrops alters subfoveal choroidal thickness.
MéthodesThree drops of tropicamide 0,1% and phenylephrine 2,5% were administrated to the right eye of 28 healthy volunteers. The high resolution OCT EDI scans (Spectralis, Heidelberg Engineering) of the right and the left eye were performed before and 15, 30 and 60 minutes after eyedrops administration (8 measurements). Subfoveal choroidal thickness was measured manually by two independent observers.
RésultatsThe average age of volunteers was 35.8 years +/-12.1. The interobserver repeatability was calculated and showed significant differences in each eye for 1 of the 4 time points. Therefore, the mean of the two observers were used for further analysis. The average subfoveal choroidal thickness (SFCT) before eyedrops administration of the right (369.74µm +/- 81.91) and of the left eye (347.98µm +/-65.00) were significantly different (p<0,03). No difference in mean SFCT was observed in each eye after drops administration at any time points (p between 0.087 and 0.99).
ConclusionOur results do not show subfoveal choroidal thickness changes 15, 30 and 60 minutes after tropicamide and phenylephrine administration.
