Increase of Intraocular Pressure after Application of 0.125% Atropine Eye Drops in Children Using Ortho-K Contact...

This report describes a case of elevated intraocular pressure following the use of 0.125% atropine eye drops in a child wearing orthokeratology lenses.

A 9-year-old boy presented to our clinic with myopia, and he had been wearing orthokeratology lenses overnight for 23 months. He was treated previously with a once-daily administration of topical 0.125% atropine eye drops to reduce myopic progression. Three days after treatment, his intraocular pressure was 36 mm Hg in the right eye and 32 mm Hg in the left eye. Two days after the discontinuation of atropine eye drops and overnight orthokeratology lenses, the intraocular pressure was 18/20 mm Hg in both eyes.

Low-dose atropine eye drops can cause intraocular pressure elevation in patients wearing overnight orthokeratology lenses. Although it may resolve promptly, short-term follow-up with intraocular pressure checks may be necessary for the early diagnosis and treatment of this complication.
