Primary Open Angle Glaucoma (P.O.A.G) is widely prevalent all over the world. It is usually asymptomatic until advanced stage where there may be either irreversible marked visual field loss or advanced optic nerve head damage or both. So, much emphasis is to be given in early diagnosis. The present study was therefore, conducted at OPD of our Institute to study the followings:

  1. Prevalence of P.O.A.G. and its relationships with age, sex, religion, dietary habits, educational and emotional status, heredity, geographical pattern and socio-economic status, anterior chamber depth and axial length of the eye ball.
  2. Its relationship with some systemic disorders (e.g. diabetes, Hypertension, Hyperthyroidism, cardiovascular disorders, corticosteroid therapy and refractive error).

Materials and Methods:

This study included thorough history taking, routine clinical examination and special investigation like gonioscopy, applanation tonometry, perimetry (by Goldmann perimeter and Automated Perimeter in a limited number of patients). The present study was conducted with the following criteria on 184 patients (368 eyes) of P.O.A.G out of 53,840 patients attending the O.P.D. of our Institute from August, 1995 to February, 1996.

  1. I.O.P 21 mm. of Hg. by applanation
  2. Anterior Chamber is open gonioscopically
  3. Glaucomatous changes of optic nerve head and peripapillary retina
  4. Glaucomatous change in the visual field

Besides open angle of anterior chamber, presence of at least two of the above mentioned criteria were considered for diagnosis. The patients having congenital glaucoma or patients attending glaucoma clinic irregularly, non – cooperative patients and patients with advanced lental changes were excluded in this study.
