Elevación de la presión intraocular secundaria a desprendimiento de retina / Increased intraocular pressure secondary to retinal detachment

Se describen 4 casos clínicos de pacientes con desprendimiento de retina regmatógeno (DRR) asociado a elevación de presión intraocular (PIO) en el momento del diagnóstico del DRR. Todos los pacientes eran hombres que acudieron a urgencias por miodesopsias, presentaban inflamación leve a moderada en cámara anterior y elevación de la presión intraocular mayor de 30mmHg. En todos ellos se detectó la presencia de DRR. Esto demuestra que los desprendimientos de retina no siempre presentan la PIO baja, y es compatible con valores de PIO alta. En esos casos de enfermedad retiniana y PIO elevada, se debe examinar minuciosamente la cámara anterior y el fondo de ojo para que no pase desapercibido un desprendimiento de retina que requiere tratamiento inmediato. Esta asociación de una PIO elevada y un DRR se denomina síndrome de Schwartz-Matsuo (AU)

Four clinical cases of patients with rhegmatogenous retinal detachment (RRD) associated with elevated intraocular pressure (IOP) are described. All the patients were men who came to the emergency service with floaters, all presented mild to moderate inflammation in the anterior chamber and increased intraocular pressure greater than 30mmHg. All were diagnosed of RRD. This demonstrates that a RRD does not always present low IOP. In these cases of clinical retinal pathology and high IOP, we must carefully examine the anterior chamber and the fundus of the eye so that an associated retinal detachment does not remain unnoticed, and can be treated immediately. This association of elevated IOP and RRD is called as Schwartz-Matsuo Syndrome (AU)

Increased intraocular pressure secondary to retinal detachment.

All the patients were men who came to the emergency service with floaters, all presented mild to moderate inflammation in the anterior chamber and increased intraocular pressure greater than 30 mmHg.

In these cases of clinical retinal pathology and high IOP, we must carefully examine the anterior chamber and the fundus of the eye so that an associated retinal detachment does not remain unnoticed, and can be treated immediately.

PURPOSE: To evaluate the accuracy of disk size and cup/disk ratio (C/D) estimation by measuring the vertical diameter and cup/disk ratio at the slit lamp. METHODS: Two hundred and thirty eight eyes of 185 people, 82 glaucomas and 156 normal subjects were included. All underwent slit lamp examination, tonometry, optic nerve photographs, scanning laser tomography (HRT) and standard perimetry (Humphrey). Correlation between slit lamp measurements (vertical diameter and C/D ratio) and HRT parameters was evaluated. RESULTS: There is a significant correlation between the disk diameter measured at the slit lamp and the disk area measured with HRT (Pearson Test, r: 0.52, p<0.001). Additionally, there is significant correlation between the semi-quantitative estimation of C/D ratio at the slit lamp and the C/D area ratio from the HRT (r: 0.83, p<0.001). CONCLUSION: Measuring the vertical diameter and the C/D ratio at the slit lamp is a useful method for estimating the real disk area and C/D ratio. It is highly recommended that disk size be estimated when attempting to interpret clinical findings in the optic nerve head.

Objetivo: Evaluar la precisión de la estimación del tamaño de la papila y el índice excavación/papila (E/P) mediante la medición del diámetro vertical y la excavación en la lámpara de hendidura. Método: Se incluyeron 238 ojos de 185 personas, 82 con glaucoma y 156 normales. Todos fueron examinados con lámpara de hendidura, tonometría, fotografías del nervio óptico, tomografía con láser confocal (HRT) y perimetría estándar (Humphrey). Se evaluó la correlación entre el diámetro vertical de la papila y el índice excavación/papila (E/P) medidos en la lámpara de hendidura (lente de 90 o 78 dioptrías) y varios parámetros objetivos obtenidos con el HRT. Resultados: Existe una correlación estadísticamente significativa entre el diámetro papilar estimado mediante biomicroscopía y el área de la papila calculado por el HRT (Test de Pearson, r: 0,52, p<0,001). Asimismo se observó una correlación estadísticamente significativa entre la estimación semicuantitativa del índice E/P obtenido por biomicroscopia y el parámetro área de la excavación/área de la papila calculado por el HRT (r: 0,83; p<0,001). Conclusión: La medida del diámetro vertical y del índice E/P en la lámpara de hendidura es una buena estimación del área de la papila y del cociente área excavación/área de la papila. Se recomienda la valoración del tamaño de la papila a la hora de interpretar los hallazgos clínicos observados en el nervio óptico(AU)
