Abstract
Glaucoma affects 1-2% of people over 40 years old in western developed countries and accounts for 8 - 15% of new registrations for blindness. Primary open-angle glaucoma corresponds to a progressive loss of retinal ganglion cells characterized by an excavation of the optic disc associated with typical visual field defects. The early detection of glaucoma is imperative for functional vision preservation. The fact that early glaucomatous damage can occur close to fixation would not matter if the 24-2 (6° grid) test did as well as the 10-2 (2°grid) test in detecting early macular damage. This study was carried out at ophthalmology department, Tanta university hospitals; the study was included 30 eyes with mild to moderate glaucomatous optic neuropathy. All patients were with POAG patients all of them with glaucomatous optic neuropathy on fundus examination. Only eyes with reliable 24-2 and 10-2 VFs, defined as fixation losses of 33% or less, false positives of 15% or less, and false negatives of 20% or less were inclouded. The following results were obtained: There was positive significant correlation between 24-2 and 10-2 at diagnosis of central scotoma as p value was (P=0.016). There was positive significant correlation between 24-2 and 10-2 at diagnosis of No significant scotoma as p value was (P=0.031). There was no significant correlation between 24-2 and 10-2 at diagnosis of other focal defect. There was a no significant correlation between 24-2 and 10-2 according to MD. There was a positive significant correlation between 24-2 PSD and 10-2 PDS which is highly significant (P<0.001).
