Abstract

Objective: To evaluate the variation of intraocular pressure (IOP) after blunt ocular trauma. Subjects and research methods: Descriptive study on 43 blunt ocular trauma eyes of 43 patients who had examination and treated at the Eye Trauma department of Vietnam Nation Eye Hospital from 12/2021 to 5/2022. Results: The male/female ratio in the study was approximately 5.5/1. The mean age was 43.56 ± 16.83 years old (the oldest was 73 YO and the youngest was 8 YO). In which, the group with the highest rate was 18 – 60 years old (74.4%), this was the working age group. Most of the cases of injury were occupational accidents, accounting for 55.8%. The mechanism of injury was mostly direct force, accounting for 93%, and only 7% were indirect injuries. Most of the patients presented with very poor vision, the highest rating group was VA < CF1m, accounting for 62.8% (24/43), the group of VA from CF1m to ≤ 20/70 was 35% (15/43), 1 patient with vision loss and no one had BCVA ≥ 20/50. At presentation, there were 8 eyes with low IOP (18.6%), 8 eyes with normal IOP (18.6%) and 27 eyes with high IOP (62.8%). In our research, blunt trauma damaged many parts of the eyeball, leading to changes in IOP. In which, the percentage of hyphema was 48.9% (21/43), vitreous hemorrhage was 34.9% (15/43), anterior chamber angle damage accounted for 69.8% (30/43), lens damage accounted for 76.7% (33/43) and cyclodialysis cleft was only 13.9% (6/43). Conclusion: Blunt ocular trauma causes damage to many parts of the eyeball in many levels, then leads to complicated IOP changes in the traumatized eye.
