    Accomodation lag among corrected myopes and emmetropes: A comparative study
    (IJRSFP, 2018-12-28) Azuamah, Y. C.; Kalakeya, L. C.; Esenwah, E. C.; Ikoro, N. C.; Megwas, A. U.; Azuamah, E. C.
    Accommodation lag is the amount by which the accommodative response of the eye is less than the dioptric stimulus to accommodation. This study was carried out at the Optometry Teaching Clinic, Federal University of Technology, Owerri, Nigeria to compare the accommodation lag of corrected myopes and emmetropes. A total of 68 subjects between the ages of 18 and 30 and a mean age of 23.15±2.85 were used for this study. The accommodation lag was determined by taking the difference between the static and dynamic retinoscopic findings of each subject. Results obtained showed that 18(26.47%) myopes recorded a value of between -0.25DS and -1.00DS for both static and dynamic retinoscopy. For a finding of -1.25DS to -2.00DS, there were 7(10.29%) and 8(11.76%) myopes for static and dynamic retinoscopy respectively. The distribution of retinoscopic findings among emmetropes showed that 17(25%) and 7(10.30%) emmetropes recorded a value of between plano and -0.25DS for static and dynamic retinoscopy respectively. For a finding of +0.25DS to +0.50DS, there were 16(23.53%) and 20(29.41%) emmetropes for static and dynamic retinoscopy respectively. The mean value for accommodation lag among the myopes was 0.35±0.24D. For the emmetropes, the mean accommodation lag was 0.24±0.27D. Data analysis with SPSS version 21 using the Independent Sample T test revealed that there was no significant difference (P>0.05) in accommodation lag between the corrected myopes and the emmetropes used in this study. Myopes were advised to always put on their prescription glasses to ensure an improvement of their accommodative response.

    Visual acuity and imparment among hypertensive adults in Okagwe Ohafia, Abia State, Nigeria
    (U. P., 2011) Azuamah, Y. C.; Amadi, A. N.; Esenwah, E.; Amadi, C. O. A.; Azuamah, E. C.
    The objective of this study is to determine the level of reduction in visual acuity and visual impairment arising from ocular diseases among adults with hypertension. A community based study was conducted in a rural community in Abia State, Nigeria. A total of 213 subjects were screened for ocular diseases and impairments. Eighty seven (40.8%) males and 126 (59.2%) females were used for the study. The demographic data of the participants were taken. Furthermore, the arterial blood pressure was measured using the KODEA electronic sphygmomanometer. The case history of those who participated in the study, the visual acuity and other ocular examinations were taken. Out of the 213 subjects used for this study, 117 subjects had high blood pressure comprising of 54 (46.2%) males and 63 (53.8%) females. The visual acuity of both right and left eyes of the subjects with hypertension revealed a poor or absent visual acuity of 6/60 or less was seen in 58% of the male subjects and 53.9% of the female subjects. The major causes of visual impairment in this population were attributed to cataract and glaucoma which was present in 37.6% and 32.8% of the subjects respectively. Other associated factors of visual impairment recorded were hypertensive retinopathy, optic neuropathy, macular degeneration and diabetic retinopathy.
