Comparison of p100 latency and amplitude between Dominant and non dominant eye
Journal Title: INTERNATIONAL JOURNAL OF CURRENT RESEARCH - Year 2015, Vol 7, Issue 8
Abstract
Introduction: Ocular dominance may be especially important in sports which require aim, such as archery, darts or shooting and it is an important consideration in predicting patient satisfaction with monovision correction in cataract surgery, refractive surgery and contact lens wear. The present study was therefore conducted to determine the ocular dominance. Materials and Methods: 41 normal healthy subjects, 17 male and 24 female were participated in this study. All were aged between 17 to 21 .Subjects with corneal opacity, squint, color blindness, those on miotic and mydriatic drugs and those with other neuromuscular disorders were excluded. Ocular dominance was first tested by Miles test and then to confirm the eye dominance VEPs (Visual Evoked Potential) were performed by checker board pattern reversal stimuli system. Results: In this study Miles test revealed that, out of the 17males, 15 were right eye dominant and 2 were left eye dominant. Out of the 24 females, 15 were right eye dominant and 9 were left eye dominant, and the results were confirmed by VEP analysis. It was found that P100 Latency obtained by stimulating the dominant eye was significantly shorter with a P value of 0.0017 and Amplitude greater with a significant P value of 0.0001 compared to the non dominant eye. Conclusion: The results of this study demonstrate that eye dominance occurs in individuals. It may be beneficial in monovision correction of certain ophthalmic surgeries like, cataract surgery, refractive surgery and in contact lens wear and also useful in sports which require aim, such as archery, darts or shooting.
