The Demography and Etiology of Pediatric Enucleation in a Tertiary Eye Center in North China, 2001-2015.

PURPOSE: To review the demography and etiology of pediatric enucleation over time.

METHODS: Pediatric ophthalmic inpatients recruited and recorded (aged 0-14 years) at Shandong Eye Institute from January 2001 to December 2015 were reviewed. Changes during the three periods from 2001 to 2005, 2006 to 2010, and 2011 to 2015 were compared and analyzed.

RESULTS: A total of 9307 pediatric inpatients were reviewed. Of these, 71 patients (71 eyes) who had been treated by enucleation were analyzed; 46 were boys (64.79%) and 25 were girls (35.21%). The mean age at enucleation was 9 (0-14) years. The pediatric enucleation rate during this 15-year period was 0.76% (71/9307), with a decreasing trend (p < 0.001). From 2001 to 2005, the figure was 3.45% (43/1245); it dropped to 0.80% (26/3231) from 2006 to 2010 and then dropped further to 0.04% (2/4831) by 2015. Trauma (52.1%, 37/71) was the leading etiology. Overall, 89.2% (33 eyes) exhibited open globe injuries; 78.4% (29/37) of these involved boys. In the cases with open injuries, the mean age at the time of trauma was 6.0 (0-14) years and the mean age at enucleation was 11 (2-14) years. Retinoblastoma (RB) (22.5%, 16/71) was the second-most common etiology; 68.8% (11/16) of these cases involved girls and the mean age at enucleation was 2 (0-5) years.

CONCLUSION: A decrease in pediatric enucleation in North China, especially in Shandong Province, was observed over time, possibly because of better surgical techniques, improvements in the treatment of RB, and public health interventions in children.
