    Age and gender variations of visual impairment in the distribution of cataract at Ehime Mbano, Imo State, Nigeria
    (U. P., 2015-03) Azuamah, Y. C.; Amadi, A. N; Esenwah E. C.; Agu, G. C.; Okorie, M. E.
    This study was carried out in Ehime Mbano Local Government Area of Imo state, Nigeria, to assess the age and gender variations in visual impairment among individuals with cataract. Out of 233 subjects examined, 68 males and 68 females were found to have cataract. The mean age of the male subjects was 61.37±13.97 while the mean age of the female subjects was 56.78±14.05. Results of the best correctable visual acuity of the male and female subjects in the better eye using the WHO classification revealed that 33 (24.26%) males and 28 (20.60%) females were normal with a best correctable visual acuity of 6/6 to 6/18. Twenty four (17.65%) males and 25 (18.38%) females had visual impairment with a visual acuity of <6/18 – 6/60. Severe visual impairment was seen in 5 (3.67%) males and 4 (2.94%) females. Subjects in categories 3, 4 and 5 were labeled blind according to WHO definition with a male frequency of 1 (0.74%), 4 (2.94%) and 1 (0.74%) respectively. The female frequency was 4 (2.94%), 5 (3.67%) and 2 (1.47%) respectively. SPSS statistical software analysis using the paired sample T test showed that the age and gender variations in visual impairment was statistically significant at 0.05 level of significance and 95% confidence interval, t(67)= -4.394, (p<0.05).

    Co-occurrence of systemic hypertension and glaucoma in Southeast Nigeria
    (U. P., 2015) Azuamah, Y. C.; Amadi, A. N.; Esenwah, E. C.; Agu, G. C.; Okorie, M. E.
    The co-occurrence of systemic hypertension and glaucoma was investigated in rural communities of southeast Nigeria. Four hundred and forty six subjects were examined of which 186 (41.7%) were males and 260 (58.3%) were females. Three hundred and forty of the subjects had either hypertension, glaucoma or both. From this number, 183 (53.82%) subjects had hypertension, 157 (46.18%) had glaucoma and 106 (31.17%) had both hypertension and glaucoma. Among the subjects with hypertension, 46.99% were males and 53.01% were females. For the subjects with glaucoma,there were 42.04 % males and 57.96% females. For the subjects who had both hypertension and glaucoma, 44.34% were males and 55.66% were females. Proper awareness and health education campaigns toward mitigating the impact of hypertension and glaucoma was recommended.

    Intraocular pressure changes in different degrees of myopia
    (U. P., 2020) Megwas, A. U.; Onuoha, S. U.; Ugwoke, G. I.; Okorie, M. E.; Ibe, C. N.; Azuamah, Y. C.; Daniel-Nwosu, E. I.; Nwawume, I. C.; Umunnakwe, L. O; Ogbonna, U. C.
    Myopia is a refractive condition of the eye in which the images of distant objects are focused in front of the retina when accommodation is relaxed. Intraocular pressure (IOP) is the pressure within the eyeball. This study was carried out to investigate the intraocular pressure changes in the different degrees of myopia. The study was a clinical study carried out at the Department of Optometry Teaching Clinic, Federal University of Technology, Owerri, Imo state, Nigeria. Clinical tests performed on the subjects include case history, visual acuity, external eye examination, ophthalmoscopy, static retinoscopy and subjective refraction. The subjects with myopia were grouped into three according to the degree of myopia. Their intraocular pressure was measured using the indentation tonometry. A total of 50 subjects were used for this study. Twenty-five (50.00%) of the subjects had low myopia; 21 (42.00%) had medium myopia and 4 (8.00%) had high myopia. Results showed that for subjects with low myopia, those with IOP of 10 - 15 were 10 (20.00%); 16 -20, 13 (26.00%); 21 – 25, 2 (4.00%); 26 – 30, 0 (0.00%). For subjects with medium myopia, those with IOP of 10 - 15 were 11 (22.00%); 16 -20, 10 (20.00%); none of the subjects had IOP above 20mmHg. For subjects with high myopia, none had IOP of 10 – 15 and above 20 mmHg; 4 (8.00%) had IOP between 16 and 20 mmHg. The mean IOP values were 17.13±3.97, 16.63±3.09 and 20.15±1.29 mmHg for low, medium and high myopes respectively. SPSS data analysis using the one-way ANOVA at 0.05 level of significance showed that there was a significant difference (P<0.05) in the IOP values between the different degrees of myopia. Eye care practitioners were advised to closely monitor the IOP of their myopic patients.

    Refractive power and blood glucose changes: Studies in alloxan-induced and insulin-treated diabetic rabbits
    (U. P., 2015) Okorie, M. E.; Nweke, I. N.; Ahuama, O. C.; Azuamah, Y. C.; Unekwe, P. C.
    This study was carried out to determine the refractive power and blood glucose changes in alloxan-induced and insulin-treated diabetic rabbits. Eighteen healthy Dutch rabbits of both sexes weighing between 1.1kg and 1.9kg were used for this study. A 5% solution of alloxan monohydrate was administered intravenously to create a diabetic state. Refraction and blood glucose measurement was measured at approximately 5 days interval for 15 days before and after induction of diabetes by Streak retinoscopy. Results show a significant increase in hyperopia from + 1.49 D (+/- 0.59) to + 2.00 D (+/- 0.52) with increased blood glucose level after induction of diabetes. There was a significant positive correlation (P = 0.01) between hyperglycemic and hyperopic changes in the diabetic rabbits (r = +0.913, P<0.05). On the other hand, there was no significant correlation between insulin-induced blood glucose and refractive changes in insulin treated diabetic rabbits (r = +0.31, P > 0.05).
