Correlation of contrast sensitivity with the severity of primary open angle glaucoma
Journal Title: Indian Journal of Clinical and Experimental Ophthalmology - Year 2018, Vol 4, Issue 4
Abstract
Aims To assess the contrast sensitivity CS in different stages of primary open angle glaucoma and to correlate it with the severity mild moderate severe of glaucomaMaterials and Methods This prospective randomized study was conducted at Sapthagiri institute of medical sciences and research centre Bangalore between June 2017 December 2017 A total of 100 eyes of 55 individuals aged 2580 years diagnosed with POAG were enrolled in this prospective study Selected subjects underwent detailed ophthalmic examination including ocular history slit lamp examination objective subjective refraction if required to obtain best corrected visual acuity BCVA on Snellen visual acuity chart and dilated fundus evaluation using indirect ophthalmoscopy Eyes with clear media and BCVA 660 were included and contrast sensitivity was measured using Pelli Robson chart at 1 meter distance HFA report of included subjects were collected from Glaucoma department to classify them in to mild moderate and severe groups according to their visual field findings pattern deviation of HFA report Classification was done according to International statistical classification of disease and related health problem ICD 10 One way ANOVA and ttest was used to analyze the dataResults There was 36 mild 26 moderate and 38 severe cases of POAG classified according to ICD 10 The mean value of contrast in mild moderate and severe POAG was 14341 13267 and 11326 respectively An analysis of variance tested whether there were significant difference in contrast sensitivity among mild moderate and severe POAG Results indicated that these means differed significantly p 0Conclusion There was decrease in contrast sensitivity with the severity of POAG Thus the contrast sensitivity testing should be made mandatory in evaluating POAG patients which could help in screeningdiagnosis early detection and to assess the progression of the disease as well as response to the treatmentKeywords Contrast Sensitivity Primary open angle glaucoma Visual fields
