Purpose: The study was to investigate the effect of fatigue severity on dry eye syndrome in adults.
Methods: Structured questionnaires were used for 365 adults (97 males, 268 females), participants of sex, age, ocular history including basic population, sociological variables and with the investigation of lifestyles, including, were to write to self-evaluate FSS (Fatigue Severity Scale), OSDI (Ocular Surface Disease Index).
Results: The mean fatigue severity of 365 subjects was examined as 4.52 ± 1.37. When divided by 3.22 into the low fatigue group and the high fatigue group as node, the low fatigue group was 19.5% (71 people) and the high fatigue group was 80.5% (294 people). The prevalence of dry eye syndrome was 88.8% (324 people), mild 21.6% (79 people), moderate 15.9% (58 people) and severe 51.3% (18 people). Dry eye syndrome was on the severity of the low fatigue group in severe 29.6% (21 people), moderate 21.1% (15 people), mild 32.4% (23 people), normal 16.9% (12 people), in the high fatigue group severe 56.5% (166 people), moderate 32.5% (23 people), mild 19.1% (56 people), normal 9.9% (29 people). Dry eye syndrome was significantly different according to fatigue severity (F = 70.851, P = 0.000).
Conclusions: The results of the analysis of the effect of dry eye syndrome according to fatigue severity showed that the higher the fatigue, the more eye fatigue is considered to be dry.
