Demographics and Clinical Characteristics of Open- Globe Ocular Trauma at a Tertiary Eye Center in the Philippines: A 5-Year Retrospective Review
Received Date: February 04, 2020; Published Date: February 19, 2020
Objective: To describe the demographics and clinical characteristics associated with visual acuity (VA) in open-globe trauma patients at a tertiary eye center in the Philippines.
Design and Methods: A retrospective cohort study of 445 patient records from January 2013 to November 2017 was done. All openglobe injuries, defined by Birmingham Eye Trauma Terminology classification system, were included . Data about demographics and clinical characteristics were collected. Baseline VA was compared to last follow-up VA, classified as excellent (>20/60), good (20/80 to 20/200) or poor (<20/200).
Results: The mean age of patients was 28.0±16.9 years. The most common objects causing injury were hammered nails at work (57/232 [24.6%]) while for children 8 years and younger they were knives at home (7/34 [20.6%]). The most common complication was intraocular foreign body (IOFB) (27/107 [25.2%]). Subgroup analysis was done on patients with at least 1-month follow-up, with mean follow-up time of 105.5±259 days. At final consult 59.6% (84/141) had excellent outcome, 12.8% (18/141) had good outcome, and 27.7% (39/141) had poor outcome. For complications, VA improved significantly between initial and last consult for eyes with vitreous hemorrhage (LogMAR 1.87±0.83 vs 1.40±1.00; p=0.022), IOFB (LogMAR 1.69±0.91 vs 1.10±0.98; p=0.011) and eyes needing penetrating keratoplasty (LogMAR 2.07±0.68 vs 1.22±0.94; p=0.007). There was no significant improvement in VA for eyes presenting with retinal detachment and endophthalmitis. Better initial VA correlated with excellent final VA (p<0.006, OR=1.131, 95% CI=0.331, 1.930).
Conclusion: Ocular trauma continues to be a common cause of preventable blindness in the Philippines, most commonly seen at the workplace. Prognosis and management of patients should be based on initial VA, and other pertinent clinical characteristics.
