Kitagawa K; Hayasaka S; Nagaki YJapanese Journal of Ophthalmology 2003; 47: 142-144
BACKGROUND: Several ocular complications, including glaucoma and ocular hypertension, have been reported in patients with nevus of Ota. CASE: A 12-year-old boy with nevus of Ota on the left side of his face was referred for further examination of elevated intraocular pressure (IOP) in his left eye. OBSERVATIONS: IOP measured with Goldmann tonometry was 19 mmHg OD and 25 mmHg OS. No visual field defects were detected by Goldmann or Humphrey perimetry. With ultrasonic pachymetry, the mean ± SD of central corneal thickness was 560 ± 4 m in the right eye and 652 ± 9 m in the left. CONCLUSION: Ophthalmologists should be aware that the abnormally thick cornea of patients with nevus of Ota may produce falsely elevated intraocular pressure readings.
