Abstract
Aim. To investigate the epidemiological characteristics of primary acquired nasolacrimal duct obstruction (PANDO).
Method. The study was a retrospective view of medical records of inpatients and outpatients who developed PANDO during a 10-year study period from 1994-2003 in Split-Dalmatian County managed at
the Eye Clinic of Split University Hospital. The total number of patients was 91.
Result. The annual incidence of PANDO was 1.96 per 100,000 inhabitants. The mean age ± SD of patients was 64.3 ± 16.0 years. There were 67 (73.6%) females and 24 (28.4%) males. The female to male ratio was 2.8, the difference was statistically significant (p = 0.000007). The differences in occurence were not statistically significant (p = 0.46) and a bilateral involvement was observed in 6 (6.6%) cases. An acute form of PANDO occured in 50 (54.9%) of cases, and a chronic form in 41 (45.1%) of cases. Although
prevalence of an acute form of PANDO was a little greater in warmer seasons (spring and summer) than in colder seasons (autumn and winter), the seasonal variations in the occurrence of PANDO were statistically not significant (p = 0.26).
Conclusion. The findings of this study are important because they make possible a better disease evaluation and better ophthalmological service planning in the treatment of PANDO.
