Abstract: Children with dry eye may not say so



BACKGROUND:
To compare the symptom scores of children with those of adults with the same degree of mild ocular surface signs.
METHODS:
This study included patients with at least one ocular surface symptom and sign. Data obtained from 45 subjects aged 8.79±2.95 yr (Mean ± SD) (pediatric group) and 45 adults aged 52.87±10.87 yr (adult group) who were matched to each pediatric patient based on ocular surface signs were analyzed. Demographic data including age and sex; parameters of ocular surface signs including fluorescein staining score, tear film breakup time and Schirmer test score; symptom scores including ocular surface disease index (OSDI) and visual analog scale (VAS) were assessed and compared between the two groups.
RESULTS:
Significant differences emerged in sex ratio as well as in age between the two groups (P<0.001, for both). Regarding ocular surface signs and tear film tests, the study revealed no significant differences in fluorescein staining score (1.44±1.95 vs. 1.40±1.68 P=0.913), tear film break up time (4.96±1.94 vs. 3.82±1.85 s, P=0.612) and Schirmer score (12.79±9.05 vs. 10.11±8.45 mm / 5 min, P=0.370). Regarding dry eye symptoms, both OSDI and VAS were significantly lower in the pediatric group (P=0.001 and<0.001, respectively) than in the adult group.
CONCLUSION:
Pediatric patients with mild ocular surface damage may report fewer dry eye symptoms compared to adult patients with similar stages of ocular surface damage.
