The study is carried out by collecting the data of tea garden's workers from different districts of upper Assam by keeping in mind the following objectives, considering seven age groups between the ages of 5 to 40 years:
To determine the Normal Frequency Distribution of Intraocular Pressure (IOP), Axial Length and Pachymetry for both eyes.
To find the Distribution of Pachymetry, IOP and Axial lengthwith Age for each age group.
To analyze the variance between Pachymetry, Intraocular Pressure and Axial Length for both eyes independently.
To study the multiple regression between Pachymetry, Intraocular Pressure and Axial Length.
A population of 100 subjects, 200 eyes were enrolled in this study. All patients were selected from the Garden's Hospital and outpatient clinic of a Private Nursing home.Patient age ranged from 5 to 40 years. Records of those patients who have gone under ophthalmic examination to measure IOP, central Pachymetry, Kerotometry and Axial length are collected. Analysis is done with the help of statistical software SPSS V.15 for windows operating system.
Study found a statistically significant relation between the IOP and the corneal curvature both in the correlation test and in the multivariate study. From the correlation table it is seen that Pachymetry and I.O.P. for the Right eye is highest for the age group of 31–35 years. Again for the Age group 26–30 years Correlation value between Pachymetry and IOP for the Right eye shows that there is very insignificant relation between them. For the Age group of 36–40 yrs, correlation value between IOP and Axial Length for the Left eye have the highest negative trend. It implies that with increase in IOP, Axial length goes on decreasing and vice versa. Pachymetry significantly affects IOP. A relation was found between corneal thickness and age by groups.
It is seen thattreatments of Axial Length, I.O.P. and Pachymetry are not alike.The highest treatment mean effects are 23.78 & 23.82 due to the feedstuff Axial Length. Hence if a choice is to be made among the three treatments Axial Length, I.O.P. and Pachymetry, treatment Axial Length is most effective.
