RESUMO
ANTECEDENTES: El tonómetro de Goldmann (TAG) es el estándar de oro para la medición de la presión intraocular (PIO). En pacientes pediátricos esta medición resulta desafiante. El tonómetro de rebote (TRB) es un instrumento fácil de utilizar. En la Unidad Nacional de Oftalmología (UNO) se reesterilizan las puntas del TRB (TRB RE). OBJETIVO: Evaluar la correlación entre el TRB con puntas nuevas y reesterilazadas en comparación con el TAG. MATERIALES Y MÉTODOS: Estudio transversal con 25 pacientes sanos entre 8 y 12 años de edad elegidos al azar, que asistieron a la consulta externa de la UNO durante el 2019. Se les tomó la PIO con el TRB usando puntas reesterilizadas, luego con una punta nueva y, por último, con el TAG. RESULTADOS: Existe correlación entre la PIO tomada con el TAG y la PIO tomada con el TRB (p = 0,0011). No se encontró correlación entre el TAG y el TRB RE, ni el TRB con el TRB RE. CONCLUSIONES: El TRB puede ser utilizado en pacientes pediátricos teniendo en cuenta que habitualmente se sobreestima la PIO con respecto al TAG
BACKGROUND: The Goldmann applanation tonometer (TAG) is the gold standard for the measurement of intraocular pressure (IOP). In paediatric patients this measurement is challenging. The rebound tonometer (TRB) is an easy to use instrument. In the National Ophthalmology Unit (UNO) the tips of the TRB are re-sterilised (TRB RE). OBJECTIVE: To evaluate the correlation between TRB with new and re-sterilised tips compared to TAG. Materials And METHODS: A cross-sectional study was conducted on 25 healthy patients between 8 and 12 years of age, chosen at random, and seen in the UNO outpatients department during 2019. IOPs were measured with TRB using re-sterilized tips and then with a new tip, and finally with TAG. RESULTS: There was a correlation between IOP measured with TAG and IOP measured with TRB (P=.0011). No correlation was found between TAG and TRB RE, or TRB with TRB RE. CONCLUSIONS: The TRB can be used in paediatric patients, taking into account that IOP usually overestimates with respect to TAG
