ICS use maintains RNFL rate

Intranasal corticosteroids (ICS) maintains retinal nerve fibre layer (RNFL) thickness and optic nerve cup to disc ratio among patients with glaucoma or glaucoma suspect.

Dr Johnson and his team, Neuro-Ophthalmology Unit, Mason Eye Institute, included 170 glaucoma or glaucoma suspect patients in a retrospective study. The rates of change in RNFL thickness and fast optic disc scan data were compared between ICS users and non-ICS users.

The results revealed there were no significant differences in superior, nasal, inferior and temporal RNFL thickness between ICL users and non-users. There was also no significant difference between the groups in horizontal and vertical cup to disc ratio.

Short-term ICS use presented no significant differences in both optic to cup disc ratio and RNFL thickness in glaucoma or glaucoma suspects.

The abstract was recently published in the European Journal of Ophthalmology.
