Non-traumatic open globe injuries: presenting characteristics and visual outcomes.
2021
PURPOSE To describe clinical characteristics and visual outcomes of non-traumatic open globe injuries. SETTING A level 1 trauma centre in a large urban medical centre. DESIGN Retrospective study. METHODS Charts of non-traumatic open globe patients admitted to MHH-TMC from 1/2010 to 3/2015 were reviewed for demographics, cause, clinical characteristics, visual acuity (VA) and enucleation. RESULTS Thirty eyes were included: 15 (50%) were males with a mean age of 47 (±28) years. All presented with zone 1 injury. Twenty-five (83%) had a perforated corneal ulcer. Presenting VA was count fingers (n = 3, 10%) to NLP (n = 6, 20%). Twenty-four (80%) involved infection, 5 (17%) congenital, 3 (10%) chemical burn and 2 (7%) neurotrophic. Conjunctival injection (n = 22, 77%), corneal opacification (n = 20, 71%) and relative afferent pupillary defect (n = 9, 44%) were common. After treatment, 23 (88%) were worse than 6/60 (20/200), 9 (35%) were NLP and 8 (27%) required enucleation. CONCLUSIONS Often non-traumatic open globe injuries are zone 1 and due to perforated infectious ulcers. Compared to previously reported traumatic injuries, these have higher rates of enucleation (27% vs 8%) and poorer final VA (88% vs 68% worse than 6/60 20/200).
