ABSTRACT

Objetivo: Estudiar la presión intraocular postoperatoria (PIOP) elevada tras la intervención de catarata pediátrica en un centro de referencia y comparar los resultados obtenidos con aquellos más relevantes de la literatura mundial. Materiales y métodos: Estudio retrospectivo observacional. Recogida de información de historias clínicas de 99 pacientes (142 ojos) operados de catarata pediátrica unilateral o bilateral entre los años 2000 y 2008. Resultados: La frecuencia de PIOP elevada (≥ 20 mmHg) fue de 79,3% en el grupo de catarata bilateral frente al 20,7% en el grupo de catarata unilateral (p = 0,032). La frecuencia de PIOP elevada entre los ojos con cirugía de catarata antes del mes de edad fue mayor, 50%, que entre los ojos en los que la cirugía de catarata se realizó después del mes de edad, 17,2% (p = 0,009). Los valores de PIOP ≥ 20mmHg se asociaron con una menor agudeza visual mejor corregida a los 5 años de la cirugía de catarata (p = 0,020). La proporción de ojos con PIOP ≥ 20 mmHg y sin lentes intraoculares fue mayor, 69%, que la proporción de ojos con PIOP ≥ 20 mmHg y lentes intraoculares, 31% (p < 0,001). Conclusiones: Un 20,4% del total de ojos estudiados presentaron PIOP elevada ≥ 20 mmHg en un periodo de seguimiento de 5 años, apareciendo con más frecuencia en aquellos con catarata bilateral que unilateral, y en ojos afáquicos que en pseudofáquicos. La elevación de la PIOP se asoció con la realización de la cirugía de la catarata a edades tempranas


Objective: To study elevated postoperative intraocular pressure (PIOP) after paediatric cataract surgery in a reference centre and to compare the results obtained with the most relevant world literature. Materials and methods: A retrospective observational study was conducted, collecting information from clinical records of 99 patients (142 eyes) operated on due to unilateral or bilateral paediatric cataracts between 2000 and 2008. Results: The proportion of eyes with PIOP ≥ 20 mmHg and bilateral cataracts was higher, 79.3%, than the proportion of eyes with PIOP ≥ 20mmHg and a unilateral cataract, 20.7% (P = .032). The proportion of eyes with PIOP ≥ 20 mmHg between the eyes with cataract surgery before one month of age was higher, 50%, than between the eyes in which the cataract surgery was performed after one month of age, 17.2% (P=.009). PIOP values ≥ 20 mmHg were associated with a lower best corrected visual acuity at 5 years after cataract surgery (P = .020). The proportion of eyes with PIOP ≥ 20 mmHg and without intraocular lenses was higher, 69%, than the proportion of eyes with PIOP ≥ 20 mmHg and intraocular lenses, 31% (P < .001). Conclusions: A PIOP > 20 mmHg was observed in 20.4% of eyes in a 5-year follow-up period, appearing more frequently in eyes with bilateral cataract than unilateral, and in aphakic eyes more than pseudophakic eyes. Elevation of the PIOP was associated with the performance of cataract surgery at early ages
