Background: Background: Vitreous hemorrhage (VH) is a condition that impairs vision and can lead to blindness if not diagnosed and managed promptly. Ocular ultrasound is commonly used for its non-invasive and rapid diagnostic capabilities, particularly in emergency settings.
Objective: To evaluate the diagnostic accuracy of ocular ultrasound in detecting vitreous hemorrhage and associated ocular diseases.
Methods: A cross-sectional observational study was conducted at the University of Lahore Teaching Hospital from October 2023 to March 2024. Seventy patients with symptomatic VH were included. Ocular ultrasound was performed using a 7.5 MHz B-scan probe. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall accuracy were calculated. Data were analyzed using SPSS version 25.
Results: The study included 43 males (61.42%) and 27 females (38.60%). Ocular ultrasound demonstrated a sensitivity of 77.8%, specificity of 35.3%, PPV of 56.0%, NPV of 60.0%, and an overall accuracy of 57.14% (p < 0.05).
Conclusion: Ocular ultrasound is a valuable, sensitive tool for the initial diagnosis of vitreous hemorrhage, but its moderate specificity suggests a need for confirmatory testing to ensure accurate diagnosis
