Intravitreal steroids can raise IOP

NEW ORLEANS — The prevalence of IOP increase after intravitreal steroid injection is greater than has been previously reported, according to a presenter here. Douglas J. Rhee, MD, spoke about his findings here at the American Academy of Ophthalmology meeting.

Dr. Rhee and colleagues reviewed results in 324 eyes with at least 6-month follow-up after receiving injections of intravitreal Kenalog (triamcinolone acetonide, Bristol-Myers Squibb) to determine the prevalence of clinically significant IOP elevations. Triamcinolone is currently being investigated as a treatment for diabetic macular edema, Dr. Rhee said.

The researchers found that 48% of the eyes developed a “significant” IOP elevation, defined as more than 5 mm Hg, he said. Moreover, 35% of those patients had an IOP increase of more than 10 mm Hg. Among the eyes with elevated IOP, 42% had the initial elevation within 1 month, while 17% were seen at 6 months.

“There were a large number of subjects with repeat injections,” Dr. Rhee said.
