Purpose: Keratoconus is an ectatic disorder of cornea and mostly involve teen aged group, still the pathogenesis and aetiology is not clearly defined. We try to establish the progression of the diseases is inversely proportional to the age of onset of the patient. Design: It was an observational study, carried out at a private eye hospital where patient was referred for RGP contact lenses. Methods: This observational study was carried out from Jan’ 2017 to Dec’ 2019 total three year period and 304 patients with Keratoconus were in the initial study and we divided them into two groups. Group: A, ≤25 years old and Group: B, >25 years old but among these 304 patient we included 200 patients in our study those who completed minimum 3 years follow-up and meet the inclusion criteria. Results: After three years ‘K’ value in group: A, <0.0001 in group: B, <0.3655. Sim K’s Astigmatism <0.0001 in group: A. <0.0223 in group: B. Central corneal thickness <0.0001 in group: A and 0.1957 in group: B. ‘K’ value and central corneal thickness (CCT) deteriorate more in group: A, than group: B. It is also found that KC progress more in case of VKC and it is more prominent in dominant hand side. Conclusion: At diagnosis, keratoconus is often more advanced in children than in adults, with faster disease progression. Early detection and close monitoring are therefore crucial in young patients.
Purpose: Preeclampsia and eclampsia is one of the leading causes of maternal and fetal morbidity and mortality worldwide. Visual disturbances in (pre)eclampsia seem to be frequent phenomena. Therefore, the obstetrician/gynecologist may encounter women with serious, and sometimes debilitating, pathology of the visual pathways. Methods: This is a cross sectional observational study was conducted over a period of 12 months (January 2016-December 2016) at Dhaka Medical College Hospital, Dhaka, Bangladesh. Patients with severe preeclampsia and eclampsia were included in the study. The association was measured with Chi-squared test and p value of 0.05 was treated as significant. Results: During this 12-month period, 100 patients with severe preeclampsia and eclampsia were studied the mean age was 26.4 ± 5.5 years. The association between retinal changes and different variables was statistically significant positive association between the presence of retinal changes and blood pressure (P= 0.0118), proteinuria (P= 0.0025). However, age (P= 0.7123), and gravida (P= 0.7998) were not associated with occurrence of retinopathy in our study. The most common retinal change was noted and narrowing of arterioles, (83%) that retinal changes were significantly more in patients with severe hypertension, exudate (12%) and haemorrhages (10%) observed in present study. The presence of macular edema (5%) and retinal detachment (2%) are the warning signs for termination of pregnancy to save the vision of the mother. Conclusion: It is called that eye is the gateway of medicine, so in pregnancy induced hypertension presence of changes in the retinal arterioles and retinal haemorrhages may indicate similar changes in the placenta. Since the well-being of the foetus depends on the placental circulation, ophthalmoscopic examination of mother’s fundus may give a clue to similar micro-circulation changes in the placenta and indirectly to the foetal wellbeing.

Background: Myopia, or nearsightedness, affects a large percentage of the population and is typically identified in those under the age of 20. Having myopia makes it difficult to see far away. While you have no issue seeing nearby items, such as those used to indicate aisles in a grocery store, you may have trouble seeing further away ones, such as road signs. Objective: In this study our main goal is to evaluate the distribution of iris colour and its relationship to myopiain Bangladeshi patients. Method: This cross-sectional study was carried out at tertiary hospital from March 2020 to December 2021, researchers from several fields and sessions worked together on a single unified study. There were a total of 100 people, with a best corrected visual acuity (BCVA) of 6/6, and ages ranging from 11 to 25 years old. Patients were limited to no more than six hours of television every day. All three degrees of myopia (mild, moderate, and severe) were covered. Results: During the study, 51% belong to 10-15 years followed by 35% belong to 16-20 years and 14% belong to 21-25 years. In addition, among patients mild 55%, moderate 21%, and severe 24% myopia. Screen time, significantly associated with myopia. 40% who had screen time was 1-2 hours had severe level myopia. Followed by 45% who had screen time was 2-4 hours had severe level myopia and 50% who had screen time was 4-6 hours had severe level myopia. 66% who had mid-level myopia had grade I Irish color. Followed by 56% who had moderate level myopia had grade I Irish color and 50% severe level myopia had grade I Irish color. 66% who had simple myopia had grade I Irish color. Followed by 55% who had curvatural myopia had grade I Irish color. Conclusion: Darker iris color was linked to higher myopia-related refractive errors, even when other known myopia-related risk variables were taken into account.
Background: Myopia, often known as near-sightedness, is a common visual issue that typically first appears between the ages of 6 and 14. Roughly 5% of toddlers, 9% of elementary schoolchildren, and 30% of high schoolers are affected. Having near-sighted parents increases a child's risk of developing myopia. Objective: To assess the prevalence of myopia among school students in urban area Bangladesh and to explore the associations between reading and writing postures and myopia. Methodology: A complicated, stratified, multistage sample design was used to select the participants from January 2019 to January 2020. Using a random number generator, we chose one urban region and one rural area in Bangladesh, and at least 50 students from each grade in elementary, middle, and high school participated in the studies. Students from elementary school (n=50), middle school (n=50), and high school (n=50) were all included in our study, which included a total of 150 participants. Results: During the study, mean age of the patients was 10.50± 0.86 years. Followed by middle school group mean age was 14.09 ± 0.92 years and high school group was 16.55 ± 0.89. Plus majority were male. In primary school group 35% cases usually had their chest is more than the width of a fist from the edge of the table. Followed by in middle school group it was 25% and in high school group it was 27%. Plus, in primary school group 26% had usually eyes are more than 33 cm (one Chi) away from the book followed by in middle school group it was 30% and 31%. Regarding the associations between reading and writing postures and myopia, we identified that a reading distance >33 cm is a protective factor for myopia in female students [odds ratio (OR) = 0.31, 95% confidence interval (CI) = 0.15–0.64], in both primary school (OR = 0.55, 95% CI = 0.30–0.99) and middle school (OR = 0.37, 95% CI = 0.15–0.90) Conclusion: A reading distance >33 cm can be used as an additional measure to prevent and control myopia. Proper postural measures for reading and writing may have educational and public health benefits.
