Glaucoma and Drusen of the Optic Nerve Head

Abstract

Purpose: to present 28 patients with optic nerve head drusen (ONHD). Ten had coexisting glaucoma. We tried to evaluate if there was any correlation between the clinical picture of ONHD and the visual field defects and whether glaucoma exacerbated any of the clinical parameters in these patients. Methods: basic clinical examination, Goldmann applanation tonometry, visual field, HRT II, Ishihara colour testing, pupil reaction, central corneal thickness, corneal endothelial cell count, VER and laboratory investigations were performed in all patients. Results: There was an abnormal retinal nerve fiber layer (RNFL) thickness and visual field defects in 90% of patients. There was no correlation between the clinical picture of ONHD and the visual field defects among patients. This correlation was found in individual patients when an interocular comparison was made.
