Resumen


Objetivos: Determinar el espesor del complejo ganglionar celular (CGC) mediante tomografía de coherencia óptica de dominio de Fourier (FD-OCT) en pacientes con diagnóstico de hipertensión ocular previa clasifi cación del riesgo de conversión a glaucoma utilizando la regla STAR (Scoring Tool For Assessing Risk).
Materiales y Métodos: Mediante la revisión de historias clínicas, se seleccionaron pacientes con diagnóstico previo de hipertensión ocular (HTO). A cada paciente se le realizó una valoración oftalmológica completa, medición del espesor del CGC mediante OCT y calculo del STAR. Los datos obtenidos se relacionaron con variables demográfi cas, presión intraocular, paquimetría central y perimetría computarizada. 

Resultados: Se analizaron 106 ojos de 53 pacientes con HTO. La PIO promedio fue de 23.55 ± 0.69 mmHg. La regla STAR fue aplicada en 96 ojos. El 65.6% (63 ojos) se categorizó en alto riesgo de conversión a glaucoma en los próximos cinco años. Los pacientes de este grupo presentaron un espesor del CGC significativamente menor que el de los otros grupos. El valor promedio del espesor del complejo ganglionar superior e inferior fue de 83 ± 4.5 micras y 82.09 ± 4.98 micras respectivamente.

Conclusión: Los pacientes clasifi cados en el grupo de alto riesgo STAR tienen espesores del CGC significativamente menores. La disminución del espesor del CGC se correlacionó positivamente con las anormalidades registradas en la perimetría computarizada.
