Purpose: The purpose of the study was to illustrate the range of normal values of corneal densitometry using Pentacam Scheimpflug camera. Methodology:Prospective study was conducted at tertiary care Amanat eye hospital. 490 eyes of 490 participants of different age groups were added. All scans were performed in diagnostics room with uniform ambient light, performed by trained ophthalmic technologist. All participants were Pakistani of different ethnic groups. Only one eye of each participant was included to control biasness. T test, One-way ANOVA, pearson correlation coefficient and linear regression model tests were applied for analysis.Results: 490 eyes; 247 right eyes and 243 left eyes were analyzed. Mean age was 41.7±15.27 years (range 20-81 years) with 48.4% male and 51.6% females. based on corneal depth; highest backward scattering of light was observed in anterior (120 µm) layer (20.6±8.52 GSU) than central and posterior layers 13.6±5.17 GSU and 11.7±3.99 GSU respectively. The difference was statistically significant among layers with p< 0.001. Based on corneal surface, minimum backscattering was noted in central 0-6mm zone which increases from central to limbal zone; 0-2mm zone was 13.2±3.81 GSU, 2-6mm zone was 12.6±3.68 GSU, 6-10mm zone was 16.0±8.90 GSU and 10-12mm zone was 22.1±8.26 GSU. The difference was statistically significant with p<0.001. Significant correlation of corneal densitometry and age was observed r= 0.677, p<0.001. Conclusion:Objective assessment of corneal densitometry can be made with Pentacam Scheimpflug. Normative values of corneal density may be used in routine clinical practice and provided a reference for future research.

Objective: To compare two different teaching methods in Forensic Medicine on the basis of assessment tools. Study design and setting: A cross sectional analytical study was conducted at the Department of Forensic Medicine at Al-Tibri Medical College and Hospital, from February to August 2019 Methodology: Total 100 students of third year MBBS were included in this study after taking ethical approval from the ethical review committee. These students were randomly divided into two groups of 50 students each, with Group A being taught through the traditional didactic lectures and Group B by Team Based Learning (TBL). Both groups were assessed using different assessment tools. Each assessment was of 25 marks and for comparison of marks, independent “t” test was applied comparing the mean value through SPSS version 20.0 and the level of significance was taken at < 0.05. Results: The students involved in Team Based Learning performed superior than teacher centered strategy. In Group A, the students were taught via traditional lecture-based method and Group B was introduced to Team Based Learning. The mean score of assignment in Group A and Group B showed P value <0.001 that showed significantly higher grades in student-centered teaching. Conclusion: Team based learning showed significant successful results in all assessment methods, therefore, it has been concluded through our study that Team Based Learning is a more effective method of teaching Forensic Medicine and it helps in making learner autonomous.
