Objective: Present study aims to compare the efficacy of single dose triamcinolone acetonide suspension in suprachoroidal space and intravitreal bevacizumab in primary diabetic macular edema patients. Study design: Prospective observational study Study duration and settings: Study was conducted at department of ophthalmology, Eye Unit III, Mayo hospital Lahore (KEMU) from March 2020 to August 2020. Material and methods: The WHO calculator was used to estimate a sample size of 136 patients (66 patients in each group). Non-probability sequential sampling was used to identify patients.. Intravitreal bevacizumab injections (2.5 mg/0.1 mL) were given to patients in Group A, and triamcinolone acetonide was given to patients in Group B, all at random. After one and three months, patients were reassessed. Results: Total 135 patients were included in study. There were 71(52.2%) male and 65(47.8%) female. Mean age of patients was 41.1±6.9SD. BCVA improved 5 letters after 3 month was significantly high in TA group as compared to IVB (P=0.002). Moreover, CSF decreased at least 10% from baseline after one and three months was comparatively high in TA group (p=0.01 and p=0.04 respectively). Among all the patients in IVB group, 29.5% showed efficacy while in group TA, 37.5% showed efficacy (p=0.03) Conclusion: Triamcinolone acetonide is an efficient drug for management of diabetic macular edema. Triamcinolone had long standing effect as compared to intravitreal bevacizumab on structural and functional outcome of the patients with primary diabetic macular odema. Both interventions are associated with limited complications. Keywords: Triamcinolone acetonide, Diabetic macular edema, Intravitral bevacizumab

Objective: Objective of our study was to determine accuracy of IOL Master and A scan acoustic biometry in silicon filled eyes in terms mean difference of axial length pre-operatively and mean post-operative refractive error Study design: Comparative cross sectional study Study settings and duration: Study was conducted at department of Ophthalmology (Eye Unit III) Mayo hospital Lahore (KEMU) from November 2019 to April 2020. Material and methods: WHO calculator was used for calculation of patient sample (N=34). Patients were randomly divide in two groups Group I underwent preoperative axial length (AXL) measurement by using IOL Master and by acoustic a-scan ultrasound in Siliconized mode. Results: Total 34 patients were included in study. There were 18(52.9%) male and 16(47.1%) female. Mean age of patients was 44.2±6.4 years. Patients undergone biometry with Master IOL showed better visual acuity (Log Mar) (0.25±0.7, 0.63±0.09, p=0.000), less post-operative refractive error (0.22±0.02, 0.72±0.17, p=0.000) as compared to those in which A scan acoustic biometry was done. A significant difference in post-operative axial length was reported (p=0.04) Conclusion: IOL master is more accurate and reliable method of IOL power calculation resulting in better visual outcomes and less post-operative refractive error as compared to A scan acoustic biometry in silicon filled eyes.
