Aim. The objective of the present study was to evaluate the number and the type of surgical procedures performed in Italy from 1999 through 2004 on children <4 years with discharge diagnoses of infantile glaucoma.
Methods. The number of the following surgical procedures involving children <4 years was recorded: goniosurgery (codes 12.51, 12.52, 12.53), including trabeculotomy ab externo (code 12.54), and filtering procedure (code 12.6 and subcategories 12.61-12.66, and 12.69). The data were analyzed according to age groups, <1 and 1-4 years, and type of surgery.
Results. The total number of operations was 543. In each of the two age groups they were respectively: 65 and 22 goniosurgeries; 78 and 56 trabeculotomies ab externo; 157 and 165 filtering procedures.
Conclusion. The number of surgical procedures was very low. Goniosurgery and trabeculotomy were used above all in babies <1 year of age, even if filtering procedure was performed in most of the two age groups. Trabeculectomy resulted the most common surgery for infantile glaucoma: the total number was 205 in the 6-year period. The data we analyzed show that on addition to trabeculectomy other types of filtering procedures have been frequently used in Italy (total number: 117). Our data do not permit any reliable conclusions on incidence of infantile glaucoma in Italy. Only the mean rate per 10.000 live births (0.93±0.11) of total surgical procedures in <1 year olds might be used as a proxy indicator of the incidence of congenital glaucoma.
