简要总结
An Observation study to check the effectiveness of Novel Contrast Sensitivity Chart as compared to standard Pelli-Robson chart in measuring contrast sensitivity in clinical practice, with the inclusion criteria of K/C/O POAG,PACG ,OHT and NTG(classification based on ISGEO) , cataract and retinal related conditions: Exclusion criteria of Amblyopia, pseudophakia, corneal related conditions, secondary glaucoma, juvenile glaucoma and drug toxicity. This novel chart has been created such that, it gives the contrast sensitivity at each level of visual acuity from 1.00logMAR to 0.00logMAR unlike the standard Pelli Robson CS chart with fixed letter size all throughout the chart. This novel chart may help us in identifying the subtle progression in condition among the clincial population. Hence the study aims to check the effectiveness of Novel Contrast Sensitivity Chart as compared to standard Pelli-Robson chart in measuring contrast sensitivity in clinical practice.
