LA JOLLA, Calif. — Central corneal thickness should be considered when assessing the risk of developing glaucomatous damage in patient’s with ocular hypertension, according to researchers here.

Felipe A. Medeiros, MD, and colleagues here studied 68 patients with ocular hypertension (OH) and normal optic discs, and 63 control subjects to correlate the frequency of short-wavelength automated perimetry (SWAP) deficits. All patients underwent standard automated perimetry, SWAP and corneal thickness measurements.

Of the patients with OH, 24% showed SWAP abnormalities and 6% showed a deficit on SAP. Patients with abnormal SWAP results also had a significantly lower mean central corneal thickness than patients with normal SWAP results. Mean central corneal thickness in the patients with OH was significantly lower than in the patients with normal SWAP results.

The study is published in the February issue of American Journal of Ophthalmology.
