Objective: To find a relationship between visual acuity and contrast sensitivity testing in low vision patients of different age groups. Effect of visual acuity and contrast sensitivity on increasing age of low vision patients. Study Design: Descriptive cross-sectional study. Materials and Methods: The study included low vision patients of different age groups. Data was collected by Performa. Visual acuity was assessed by ETDRS chart and contrast sensitivity was checked by the peli-Robson chart at different distances. Data were analyzed by using SPSS 22.00. Results: The study included a total of 64 patients with low vision of different age groups. Out of 64 patients, 31(48.44%) were males and 33(51.56%) were females. Patients with age group 1-15(15.63%). Patients with age group16-30(50%) and patients with age group above 30(34.36%). Relation between CS and VA of RE with age groups. In the age group 1-15, 2 patients have VA 0.9 and CS 0.10, in age group 16-30, 4 patients have VA 0.9 and CS 0.30 and in the age group of above 30 years 2 patients have VA 1 and CS 0.30. The relation between CS and VA of LE in different age groups of low vision patients in age group 1-15, 2 patients have VA 0.7 and CS 1.35 similarly in age group 16-30, 4 patients have VA 0.9 and CS 0.30 and in the age group above 30 years 2 patients have VA 1.3 and CS 0.75. Conclusion: It is concluded that the statistical value is significant P_ 0.00 which shows a significant result. And it shows that there is a strong relationship between visual acuity and contrast sensitivity as age increases visual acuity and contrast decreases so age has to affect visual functions.

Study Participants

Aim: To determine the pattern of ocular disorders in persons with albinism and how they affect visual function. Methods: This was a descriptive cross-sectional study conducted over a five-month period on persons living with albinism in Southern Nigeria. The study participants were randomly selected during the monthly meetings of a support group known as The Albinism Foundation (TAF).Visual acuity and contrast sensitivity were assessed using the ETDRS visual acuity chart and Pelli Robson contrast sensitivity test chart. A comprehensive eye examination including dilated fundoscopy was also carried out to determine other ocular disorders. Data was analyzed using SPSS version 22 and statistical significance was set at a p-value ≤ 0.05. Results: A total of 116 PWA (232 eyes) were examined. There were 44 (37.9%) males and 72 (62.1%) females. The age of the study subjects ranged from 5 to 56 years. Most eyes were visually impaired for both distance (n=228; 98.3%) and near vision (n= 224; 96.6%). Contrast sensitivity in most eyes (n=138; 59.5%) was subnormal. With refraction and Low Vision Aid (LVA), there was significant improvement of the mean VA by 2-3 acuity lines and 6 acuity lines respectively (p=0.000). All the examined eyes had fundus hypo-pigmentation, 91.4% (n=212) had iris trans-illumination, 86.2% (n=200) had nystagmus, and 34.4% (n=80) had strabismus. Nystagmus, strabismus and iris trans-illumination significantly (p=0.00) reduced visual acuity and contrast sensitivity. Conclusion: Most study participants had reduced distance visual acuity and contrast sensitivity but with correction there was a significant improvement in vision. The presence of nystagmus, strabismus and iris trans-illumination were observed to contribute to the poor vision experienced by most persons living with albinism. Hence, early optical intervention and counselling is important in improving the quality of living of persons with albinism.

Background: Intraocular lens implantation is the only surgical approach available mostly in developing countries. Thus cataract constitutes as the leading cause of blindness in developing countries as many patients with cataract do not have access to hospitals and surgery. Objective was to study the clinical and ophthalmologic profile of patients undergoing cataract surgery.Methods: A hospital based cross sectional study was carried out among 100 cataract patients assigned to undergo conventional extra capsular cataract excision surgery for a period of two years in a tertiary care referral hospital. One day before the surgery these patients were admitted to the indoor wards of department of ophthalmology. From each patient, detailed history was obtained. Visual acuity was checked with Snellen’s visual acuity chart and pinhole improvement was noted.Results: Maximum prevalence was seen in the age group of 51-60 years i.e. 37% followed by 61-70 years of 30%. Thus cataract is seen more commonly in the age group of above 50 years. Prevalence of cataract was more in females (59%) as compared to 41% in males. Cortical cataract constituted 86% of total cases and remaining 14% were constituted by nuclear type of cataract. Majority of the patients i.e. 59% had visual acuity of less than 1/60 followed by 33% of having 5/60 to 1/60. 58% of the patients had against the rule type of astigmatism. 34% of the patients had with the rule type of astigmatism. Only 8% had NOA type of astigmatism.Conclusions: Increasing age and female gender were the most important risk factors in the present study. Cortical type of cataract was more common than nuclear type of cataract. Maximum had low vision.

Background. As people age, their vision becomes less clear; they can clearly see big objects but experience problems discerning minor things and minor details. The functional acuity contrast test is a very sensitive method used for visual system evaluation which may help to detect the beginning of the disease in case the visual acuity is still normal. Purpose. To determine functional acuity contrast sensitivity in young and in middle age healthy persons at the day time with and without glare. Materials and methods. We examined 40–49 yrs (Group 1), and 50– 59 yrs (Group 2) healthy persons. The typical Snellen chart (the direc­tion of the gap in Landolt C) was used for the non-corrected and the bestcorrected visual acuity testing. Functional acuity contrast sensitivity was measured employing a Ginsburg Box, VSCR- CST-6500, at the day time with and without glare. Results. Functional acuity contrast sensitivity remained very similar in the age groups of 40–49 years and 50–59 years. However, statistically, it significantly decreased at day time without glare (18 cycle / degree) spatial frequencies (p = 0.05). Results in Group 1 as compared to Group 2 decreased from 3.09% to 51.7% at the day time without glare and from 2.16% to 11.61% at the day time with glare. Conclusion. The facts are that contrast sensitivity remained very similar in the age groups of 40–49 years and 50–59 years at the day time with and without glare.

Objective. The aim of this study was to assess age-related visual functions (visual acuity and contrast sensitivity) and compare the results by different age groups. Material and Methods. A total of 231 patients were examined. The patients were divided into 5 age groups: 10 patients in group 1, 30–39 years; 40 patients in the group 2, 40–49 years; 77 patients in the group 3, 50–59 years; 71 patients in the group 4, 60–70 years; and 33 patients in the group 5, 71–85 years. A typical Snellen’s chart (the direction of the gap in Landolt C) was used for noncorrected and best-corrected visual acuity testing. Contrast sensitivity was evaluated by employing a Ginsburg Box, VSCR-CST-6500. Results. Noncorrected visual acuity was significantly better in the group 2 than the group 3 (0.86 [0.28] vs. 0.69 [0.33], P=0.018). Moreover, noncorrected and best-corrected visual acuity was significantly better in the group 4 than the group 5 (0.52 [0.35] vs. 0.35 [0.28], P<0.001; and 0.9 [0.21] vs. 0.69 [0.27], P<0.005, respectively). Contrast sensitivity at the nighttime without glare was significantly worse in the group 2 than the group 1 at the spatial frequencies of 3, 12, and 18 cycles per degree (P=0.001, P=0.05, and P=0.01, respectively). The patients in the group 2 had significantly worse contrast sensitivity at the nighttime and daytime with glare at the spatial frequencies of 1.5, 12, and 18 cycles per degree (P=0.054, P=0.04, and P=0.01 and P=0.011, P=0.031, and P=0.011, respectively). The greatest differences in contrast sensitivity were observed between the groups 4 and 5, and it was 2 to 4 times better in the group 4. Comparing these groups, all the differences at the nighttime and daytime with and without glare were significant. Conclusions. Contrast sensitivity was worst among the oldest persons (71–85 years), and it began to worsen already in the persons aged 40–49 years. Contrast sensitivity was very similar in the age groups of 40–49 and 50–59 years.

Background: India is a country where population is rapidly growing, to slow down this growth rate family planning is necessary. Family planning services have the potential to improve the quality of the lives and economic welfare of people. Aim of the study was to assess prevalence of unmet need, knowledge, attitude regarding family planning methods and contraceptive practices, among study participants.Methods: A cross- sectional study was carried out among females of early reproductive age group 18-25 years, Group-1 and late reproductive age group 35-49 years, Group-2Results: Out of 200 women, majority respondents belonged to age group of 22-25 years (44.5%). Females of both age-groups had almost similar (54% and 53%) knowledge “partially correct” type for objectives of family planning and had similar positive attitude (78% and 85%) towards family planning practices. Total 45% of group 1 and 55% of other group females were currently using contraception. Most common method used by group 1 women was Intra Uterine Devices (35.5%), followed by Oral Contraceptive pills (31.2%) and in group 2 women was permanent sterilization (74.5%) followed by barrier and Intra Uterine Devices (9.1% each). Unmet need of family planning was 29% and 18% among early and late reproductive age groups, respectively.Conclusions: Unmet need of family planning was higher among early age group females. In both age groups, utilization of contraceptives were less because of lack of awareness and fear of side effect.

AbstractWe analyzed the Korean National Health and Nutrition Examination Survey (KNHANES) database to determine the trends of hypertension treatment and control rate in Korea over the past 10 years. In addition, we tried to investigate the effect of chronic medical conditions on hypertension management. We investigated the hypertension prevalence, awareness, treatment, and control rate from 2008 to 2017. KNHANES, which uses a stratified multistage sampling design, is a cross-sectional, nationally representative survey conducted by the Korean government. A total of 59,282 adults (≥ 20 years) were included, which was representative of the total population of around 40 million Koreans per year. The mean age was 50.7 ± 16.4 years and 42.6% were male. The prevalence of hypertension, hypercholesterolemia, diabetes mellitus, and obesity significantly increased over the 10 years. During this period, the hypertension treatment and control rate significantly improved. Hypertension treatment rate was significantly lower in the younger age group compared to the older age group, but the control rate among the treated patients was not significantly different between age groups. The treatment and control rates of hypertension were higher in patients with multimorbidity, which implies that it has a favorable effect on the treatment and control of hypertension. Hypertension treatment and control rate have improved over the past 10 years. The higher treatment and control rate in patients with multimorbidity suggest that the more aggressive surveillance might be associated with the improvement of hypertension treatment and control rate in Korea.

Abstract Objective: To estimate the prevalence of periodontal disease with different indices. Methods & materials: The study population consisted of multistage stratified random sample of 1300 subjects from total population of district Ghaziabad. A cross-sectional study was conducted with multi stage stratified random sampling techniques to select the sample population. The subjects were divided into different age groups and the periodontal assessment was made on the basis of CPITN index and ESI Index. Results: The CPITN has shown to estimate incorrect periodontal disease prevalence because of its underestimation of the disease severity. A huge difference was noticed in the prevalence rate of periodontitis when subjects were examined with ESI index. Conclusion Periodontal disease was found to be highly prevalent in the study population and severity of disease increased with age. More number of subjects in younger age group were found to be healthy.

Factors Affecting

This is a cross sectional study conducted among Currently Married Women of Reproductive Age (CMWRA) with a sample size of 476 selected purposively using a semi-structured questionnaire in 2018 at Moulvibazar Sadar to explore the factors affecting fertility. The result shows that 55.26% respondents were within 35 years age whereas only 4.28% from age group 46-49 years age group, 33% of the respondents got married at <16 years of age and 18.70% were illiterate, 47.90% had primary education. It is evident that 76% of the respondents were from rural area; 88% were Muslims, 29.41% from lower middle class followed by upper middle class (25.42%) and poorest comprised only 7.56%. The result explored that 73.91% of the respondents were from age group 41-45 got married before 16 years of age followed by 36-40 years (68.24%), 46-49 years (66%), 20-25 and 26-30 years age groups 52.38% and 52.75% respectively; 73.33% of respondents from rural area got married at <16 years of age, 68.42% of the Muslim at <16 years. The study explored that 96.39% from poorer section and 83.33% from poorest section got married at <16 years of age. Current study revealed that 82.91% of the respondents having secondary education got married before 16 years of age followed by illiterate (82.02%). It is explored that the age at marriage is statistically associated with residence, education, wealth index and religion (p= 0.001, 0.03, 0.001, 0.001 respectively). We conclude that the sociodemographic condition contributes mostly to fertility differentials in Bangladesh.

Background: Adipose tissue mainly visceral fat is said to be harmful and acts as a harbinger of metabolic disorders. A changing trend is seen in the recent decades with decreasing incidence of metabolic disorders in men even though visceral fat is said to be higher in them. Sex hormones may influence the deposition pattern of adipose tissue. The aim of this study was to observe effects of age on visceral fat and to know if the difference in gender pattern of fat distribution is maintained throughout life or disappears after menopause.Methods: This cross-sectional observational study was conducted in Thrissur on 385 apparently healthy subjects using Omron body composition analyser. Data was analysed using SPSS 20.0 version. The tests employed were NOVA, independent samples t-test.Results: In each age group, men had significantly higher visceral fat than females. As age increased, visceral fat increased significantly in both genders. In each group, except for younger age groups, VF levels were equal in men and women.Conclusions: Visceral fat is higher in men and this difference is seen in all age groups. As age increases, visceral fat levels also increased in men and women. The distribution of visceral fat is such that a greater number of men have high to very high levels at a younger age group, a feature observed in women only in the peri and post-menopausal age. Adoption of an active lifestyle coupled with healthy diet should protect against onset of metabolic disorders.
