ABSTRACT
Objetivo: comparar la técnica de sondaje de vías lagrimales previa dilatación canalicular con gel viscoelástico con el sondaje directo. Métodos: se realizó un estudio analítico prospectivo de cohorte no concurrente en 136 ojos pertenecientes a pacientes con obstrucción congénita del conducto lacrimonasal atendidos en la Consulta de Oftalmopediatría del Hospital Pediátrico Docente Pepe Portilla, de Pinar del Río, a quienes se les realizó sondaje de vía lagrimal, desde enero del año 2008 a julio de 2013. Se conformaron dos grupos de estudio, ambos de 68 ojos, uno con la técnica quirúrgica de sondaje directo, y un segundo grupo donde se aplicó dilatación previa de la vía excretora con gel viscoelástico. Resultados: en el primer grupo se presentaron complicaciones en el 45,59 por ciento. Se logró el 54,41 por ciento de curación y fue reintervenido el 32,35 por ciento. En el segundo grupo se logró el 97,92 por ciento de curación sin complicaciones incluyendo a 6 ojos de pacientes mayores de 3 años, y fue necesario reintervenir a un solo paciente. Conclusiones: el sondaje del conducto lacrimonasal previa dilatación con Healon minimiza las complicaciones y la necesidad de reintervención, y posibilita su empleo efectivo en pacientes mayores de 3 años(AU)
Objective: to compare the lachrymal duct probing technique after canalicular dilation canalicular with viscoelastic gel or with direct probing. Methods: prospective, analytical and non-concurrent cohort study carried out in 136 eyes from patients with congenital nasolachrymal duct obstruction, who were seen at the ophthalmological pediatric service in Pepe Portilla teaching pediatric hospital located in Pinar del Rio and who underwent lachrymal duct probing in the period of January, 2008 through July,2013. Two study groups were formed with 68 eyes each, one treated with direct probing, and the other with previous dilation of the excretory duct with viscoelastic gel. Results: the first group showed some complications in 45,59 percent of patients; 54,41 percent recovered and 32,35 percent were reoperated. In the second group, 97,92 percent managed to recover without complications, including 6 eyes from patients older than 3 years. It was necessary to re-operate a patient. Conclusions: nasolachrymal duct probing after dilation with Healon minimizes complications and need for reoperation, thus facilitating its use in patients aged over 3 years(AU)

AlM:To determine the group distribution characteristics of lachrymal duct obstruction diseases in major Li Miao minority areas of Hainan province. METHODS: Totally 5 353 residents were selected and researched by randomized cluster sampling in the major Li Miao minority areas of Hainan province. Ocular examination and lachrymal duct flushing were carried out, and questionnaire survey on lachrymal duct obstruction was conducted. The ratio of lachrymal duct obstruction diseases and group distribution characteristics were analyzed based on above research. RESULTS: The prevalence ratios of lachrymal duct obstruction was 4. 47% in major Li Miao minority areas of Hainan province, with 2. 62% in urban area, and 5. 93% in rural area respectively. Prevalence ratios of men and women group were 1. 69% and 6. 39% correspondingly. Difference between the two groups was statistically significant (χ2 = 67. 2821, P = 0. 0000 ). The highest prevalence ratio was 40-69 year-old group, second one was 70-79 year-old group, especially for women in these groups. The prevalence ratios of Ledong, Lingshui, Baisha and Changjiang county were higher than those of Baoting, Qiongzhong county and Wuzhishan city. No significant difference was found between both eyes. CONCLUSlON: ln major Li Miao minority areas of Hainan province, lachrymal duct obstruction mainly occurs in 40-79 year-old patients, with specially higher ratio of women. Statistically, significant difference of the prevalence ratio between urban and rural areas exists. The higher prevalence ratio is attributed to age, gender, geographical location, climate condition, health environment and so on. The prevalence ratio is higher in the dry and windy areas than in the humid and less windy areas.
