1 in 25 Chinese adults affected by ocular trauma in SG

07 Feb 2018

Ocular trauma affects one in 25 Chinese adults in Singapore, a recent study has found, adding that around one in five of these cases require hospitalization.

A total of 3,353 Chinese adults (mean age 59.7 years; 49.4 percent male) from the Singapore Chinese Eye Study, a population-based study conducted between 2009 and 2011, were included.

Overall, 138 OT cases were recorded, yielding a crude and age and gender-standardized prevalence of 4.1 percent (95 percent CI, 3.5‒4.8 percent) and 4.4 percent (3.7‒5.2 percent), respectively. Of these, 45 (32.6 percent) were blunt object-related, 56 (40.6 percent) were sharp object-related and 10 (7.3 percent) were chemical burns-related trauma. Hospitalization was required in 28 cases (20.3 percent), with no difference between subtypes.

Multivariable models revealed that men (odds ratio [OR], 2.80; 1.79‒4.39), younger persons (per year decrease in age OR, 1.03; 1.00‒1.05) and lower education levels (comparing ≤6 years vs >6 years of education: OR, 1.8; 1.25‒2.60) were independent determinants of OT.

OT, defined as self-reported history of any eye injury requiring medical attention with or without hospitalization, was further classified as blunt object-, sharp object- or chemical burns-related.

The investigators used the 2010 Singapore Chinese population census to estimate age and gender-standardized prevalence. They used multivariable models to assess the independent associations of OT with age, gender, income, education, literacy, alcohol consumption, smoking and history of falls.

“Because OT is preventable, raising awareness and education strategies in the population would allow prevention of vision loss particularly in men, and younger and lesser-educated individuals,” the investigators said.
