Objectives: To study the role of B scan in detecting the posterior segment pathology in pre-operative cataract patients Study design: A cross sectional descriptive study Place and Duration of Study: The study was carried out at Department of Clinical Ophthalmology, Khyber girl’s medical college, Hayatabad Medical Complex (HMC), Peshawar from 15th August 2019 to 15th February 2020. Materials and Methods: This was a cross-sectional descriptive study. There were 317 eyes of 260 patients and both male and female were included in the study. First the visual acuity and detail slit lamp examination of all the patients was carried out in the OPD. Then ultra-sonography was performed in all the patients with dense cataract to evaluate the posterior segment pathology and the findings was documented in proforma. Results: In this study, we evaluated 317 eyes of 260 patients who present with dense cataract to the OPD of eye department. Among 260 patients, 58 (22.3%) patients develop cataract after a history of trauma while 202 (77.7%) have no history of trauma. On ultrasound examination 215 (67.8%) patients have no posterior segment pathology but in 102 (32.2%) patients a significant posterior segment pathology was detected. Posterior vitreous detachment (PVD) and vitreous opacities was the most common pathology among the dense cataract eyes which was 7.6% and 5.7% respectively. Which was followed by retinal detachment (4.7%) and vitreous hemorrhage in 4.7% eyes of dense cataract. Conclusions: It was concluded that in the preoperative dense cataract patients, the two-dimensional ultrasonography was the most effective tool in detecting the posterior segment pathology. It will also affect the strategy of the surgical procedure, outcome of the surgery and postoperative visual prognosis. Al-Shifa Journal of Ophthalmology 2021; 17(3):103-108. © Al-Shifa Trust Eye
