Comparative Evaluation of Rebound and Perkins Tonometer's in Pediatric Glaucoma with Varied Corneal Characteristics.

PRECIS Icare tonometer overestimated IOP as compared to Perkins and this variation was higher in IOP>19▒mmHg and corneal opacity in patients with pediatric glaucoma. PURPOSE To compare the intraocular pressure (IOP) measured by Icare ic200 with Perkin's tonometer in pediatric glaucoma with different corneal characteristics. METHODS Patients of pediatric glaucoma posted for routine examination under anesthesia, age 615 microns, and scarred corneas. A moderate correlation between IOP and CCT for both tonometers was noted.
