Background: The human eye is vulnerable to various external injuries. This is in spite of the seemingly adequate protection offered by the bony orbit. Ultrasound, as a non-invasive and safe imaging modality, is very useful in evaluating the orbit as the globe provides a perfect acoustic window. There is a need for an update on the sonographic patterns of ocular trauma in Nigeria. Objective: To sonographically assess the features of ocular trauma at the University of Benin Teaching Hospital. Methods: Eighty patients with ocular injuries were studied over an 8-month period. After detailed history taking, using a closed eye technique, each patient was scanned with a 5-12MHz linear array probe of a SONOACE X4 Machine. Results: The 18-35 years age group was most affected and the right eye was more frequently involved. The most common sources of injury were intraocular foreign bodies (26; 32.5%), assault (20; 25%) and road traffic accidents (18; 22.50%). Mechanical injuries were more common, comprising 44 (56.4%) cases of blunt trauma and 34 (43.6%) cases of penetrating trauma. The most common sonographic findings included vitreous haemorrhage, intraocular foreign bodies and retinal detachment. Conclusion: Posterior chamber findings (vitreous haemorrhage and retinal detachment) were more frequent than anterior chamber findings in ocular trauma.

Purpose: To find the epidemiological characteristics, management strategies and outcomes of intraocular foreign bodies (IOFB) in a tertiary care setup of Punjab. Study Design: Descriptive retrospective study. Place and Duration: Department of Ophthalmology, Gujranwala medical college/teaching hospital, from January 2017 to December 2019. Methods: A retrospective review, of all the patients who had IOFB removal, was performed. Information regarding the nature and circumstances of injury, types of IOFB, operative procedure performed and patient’s preoperative and post-operative best corrected visual acuity (BCVA) were analyzed. X-ray Orbit was advised to all the patients with ocular trauma having suspicion of any IOFB while CT scan was done in patients with negative Xray. Descriptive statistics were used for analysis of data. Results: Record of 22 patients was retrieved out of which 18 (81.81%) were male and 4 (18.18%) were female with a mean age of 27.95 ± 9.325 years. Occupational trauma was the leading cause of injury (66.6%). Metallic objects were among the most common type of IOFB (66.6%) followed by glass, concrete stone (each 13.3%) and lead pencil (6.6%). Serious complications seen due to retained IOFB were phthisis bulbi (9.09%), retinal detachment (13.63%) and endophthalmitis (9.09%). On follow-up, 10 patients had BCVA less than hand movement (HM), 5 patients had BCVA of CF to 6/60, 3 patients had BCVA of 6/60-6/24 and 4 patients had BCVA better than 6/18. Conclusion: Occupational trauma in young age group of working class was the most common cause of IOFB. Treatment delay and complications contributed to poor visual prognosis. [ABSTRACT FROM AUTHOR]
