Introduction: Cataract is a frequent ocular pathology in the world. The aim of our work was to study the contribution of mode B ultrasound in the diagnostic and therapeutic management of cataracts in the radiology department of the medical clinic Marie Curie in Bamako. Material and Methods: This was a prospective, descriptive study carried out in the medical imaging department over a period of 2 years. Ocular examinations were performed exclusively with a B-mode ultrasound scanner by senior radiologists. All patients who performed an ocular ultrasound for the notion of cataract were included in the study. Socio-epidemiological data, clinical information and ultrasoundresultswereanalyzed. Results: We identified 75 cases of ocular ultrasound for cataract, i.e. 73.52% of the total ocular ultrasound performed (102 cases). The median age was 49.25 years with a male predominance in 68% of cases.The state of the posterior segment and the preoperative assessment for cataract represented the most frequent indication, respectively 40% and 29.33%. Ultrasound was pathological in 68% of cases. The most common pathology was clouding of the lens (cataract) in (36% of cases). The other pathologies found on ultrasoundwereretinaldetachment (17.33%) and intraocularhemorrhage (12%) and lens dislocation (2.67%). Conclusion: Ocular ultrasound is accessible in Bamako has allowed the study of the posterior segment of the eye in the diagnostic and therapeutic management of cataracts.
