Study of correlation of retinal nerve fiber layer thickness and optic disc parameters with visual field changes in glaucoma suspects and diagnosed cases of primary open angle glaucoma
Journal Title: Medpulse International Journal of Ophthalmology - Year 2019, Vol 9, Issue 1
Abstract
Background: POAG is a major worldwide health concern, because of its usually silent, progressive nature. It is one of the leading preventable causes of blindness in the world. Purpose: To study the correlation of retinal nerve fibre layer thickness and optic disc parameters with visual field changes in Glaucoma suspects and Primary Open Angle Glaucoma. Materials and Methods: It was a hospital based, prospective, non-randomised case study of 30 eyes of 30 Glaucoma suspect patients and 30 eyes of 30 Primary open angle Glaucoma for duration of 1 year.Results: The mean age of patients in POAG group were 54.40±7.51 and in suspect group were 50.90±6.14. Correlation of RNFL thickness and Visual field indices in suspects showed no correlation between two parameters. In POAG, the average RNFL was highly correlated with mean deviation (r = 0.832).Correlation of optic disc parameters and visual field changes in suspects showed no correlation between 2 parameters.In POAG group, Horizontal Integrated rim width, CD ratio were highly correlated with mean deviation (r = 0.502), (r =0.499). The rim area was moderately correlated with mean deviation (r = 0.461). Conclusion:OCT is capable of detecting changes at the level of RNFL in Glaucoma suspects with normal appearing discs and visual fields.OCT can serve as a useful guideline in diagnosis, management, prognostication and research in Glaucoma
