Purpose: To identify and characterize defects using the automated perimetry test in patients with primary congenital glaucoma.
Methods: Automated visual fields and charts of 81 eyes (48 patients) with congenital glaucoma were retrospectively analyzed, 15 being normal eyes (group N) and 66 eyes with primary congenital glaucoma (group G). Eyes of group G were grouped in eyes without perimetric changes and with early defects, characterized by MD > -6 dB (group G I= 41 eyes), and eyes with mild/advanced perimetric defects characterized by MD < or = -6 dB (group G II= 25 eyes).
