Description
Introduction: POAG is major worldwide cause health concern, because of its usually silent and progressive nature. It is one of the leading preventable causes of blindness in the world. Aim: To study the correlation of retinal nerve fibre layer thickness and optic disc parameters with visual field changes in Normal Population, Glaucoma suspects and Primary Open Angle Glaucoma. Materials and Methods: It was hospital based, prospective, non-randomised case study of 30 patients of POAG, 70 suspects of glaucoma, and 70 Normal Age matched controls for duration of one year. Results: The mean age of patients in POAG group were 58.63±11.373. We found a correlation between VF global indices and OCT RNFL thickness parameters in the POAG. Statistically significant and positive correlation (.464) between MD and RNFL average thickness; negative correlation (-.441) between PSD and RNFL average thickness were defined in the POAG group. These correlations between MD, PSD and RNFL thicknesses are clinically important. Conclusion: SD-OCT is capable of detecting early changes of glaucoma at the level of RNFL in glaucoma suspects with normal appearing discs and visual fields. OCT has been shown to obtain accurate and reproducible RNFL and retinal thickness measurements. OCT can help in timely diagnosis of pre perimetric glaucoma. OCT can serve as a useful tool in diagnosis, management, prognostication and research in glaucoma.
