Abstract
Background: Primary open angle glaucoma is distinctly a multifactorial optic neuropathy that is chronic and progressive with characteristic acquired loss of optic nerve fibers. Aims: Recognizing field defects and disk changes among the patients with primary angle glaucoma. Settings and design: A cross sectional study was conducted in the department of ophthalmology in Narayana Medical College and hospital, Nellore from the period of 2010 to 2012. Materials and methods: Detailed clinical history and evaluation was done for all the patients and noted in the case record form. Intraocular pressure was measured by Goldmann Applanation Tonometry. Gonioscopy was done by Goldmann Three mirror gonioscope. Disk evaluation was done by both direct ophthalmoscopy and slit lamp biomicroscopy using 78D and 90D lenses. Visual field examination by Humphreys automated field analyzer ii –i series standard white on white perimetry, SITA strategy. Statistical analysis: All the qualitative data was expressed in percentages and quantative data was expressed in mean and standard deviation. Results and conclusions: The mean age of the study subjects was 4.43 ± 53.34 years with male preponderance. The most common field defect found was biarcuate scotoma. The most common disk change in the present study was advance cupping with total loss of NRR followed by Inferior NRR thinning and superior NRR thinning.
