A Preliminary study to explore the air Caloric test using Videonystagmography Among Neurotypical Adults And Individuals With Congenital Blindness

Background and Justification: These are limited studies that have documented normative data in the Indian population. As the values can vary depending on the instrumentation used and other variables, each laboratory is recommended to have its own norms (BSA, 2006). Therefore, the present study was undertaken. Aim: Air caloric using videonystagmography among neurotypical adults and individuals with congenital blindness (preliminary study). Method: To obtain representative SPV values for cold and warm irrigation (air) among neurotypical young adults for two different duration of caloric stimulation (75sec and 60 sec). To obtain representative SPV values for cold and warm irrigation (air) among congenitally blind individuals (adults) for two different durations of caloric stimulation (75sec and 60 sec). To compare SPV values for warm irrigation of 75 sec duration and 60sec duration among neurotypical young adults. To compare SPV values for Cold irrigation of 75 sec duration and 60sec duration among congenitally blind individuals Results: The outcome of the study aimed to compare SPV values for Cold irrigation of 75s duration and 60s duration among neurotypical young adults. The result revealed that there was a significant difference for the measured SPV ( table 2) between the 75s and 60s stimulation of air caloric. This significant difference was observed in RW, RIGHT BEATING, and LEFT BEATING for stimulation of air caloric among the participants of neurotypical young adults. The values were higher for 75s, and the duration was well tolerated by all participants. Therefore, it is recommended for routine clinical use. And for next objective there is no significant difference on RW, LW, RC & LC between the neurotypical group and individuals with congenital blindness (p > 0.05).
