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)

Neuropatía óptica compresiva. No todo lo que progresa es glaucoma / Compressive optic neuropathy. Not everything that progresses is glaucoma

Se presentan 3 casos clínicos de neuropatía óptica compresiva secundaria a meningiomas de diferente localización, diagnosticados inicialmente de glaucoma de tensión normal. Todas las pacientes eran mujeres de edad media, con excavación papilar, así como defectos en el campo visual asimétricos, rápidamente progresivos y deterioro de la agudeza visual, a pesar de presentar cifras de presión intraocular correctamente controladas con tratamiento hipotensor tópico. Debido a la evolución atípica de la enfermedad glaucomatosa, y sospechando una lesión compresiva del nervio óptico, se realizaron pruebas de neuroimagen, con las que se llegó al diagnóstico correcto. En casos de glaucoma de tensión normal hay que tener en cuenta como diagnóstico diferencial la neuropatía óptica compresiva. Diferenciar ambas afecciones constituye un reto diagnóstico que se debe sospechar ante la disminución atípica de la agudeza visual y deterioro de las pruebas, tanto funcionales como estructurales, de manera asimétrica y pese a las cifras de presión intraocular normales (AU)

Three clinical cases are presented of compressive optic neuropathy secondary to meningiomas of different locations, initially diagnosed with normal tension glaucoma (NTG). All patients were middle-aged women, with optic disc excavation, as well as asymmetric, rapidly progressive defects in the visual field (VF), and deterioration of the visual acuity (VA), despite presenting with intraocular pressure (IOP) correctly controlled with topical hypotensive therapy. Due to the atypical progression of the glaucoma disease, and suspecting a compressive lesion of the optic nerve, neuroimaging tests were performed, with which the correct diagnosis was reached. In cases of NTG, it is necessary to take into account compressive optic neuropathy as a differential diagnosis. Differentiating both pathologies is a diagnostic challenge that should be suspected due to the atypical decrease of the VA and deterioration of both functional and structural tests, and asymmetrically, despite the normal IOP (AU)

[Spherical aberration influence in visual function after cataract surgery: prospective randomized trial]. / Influencia de la aberración esférica en la función visual tras cirugía de catarata: ensayo prospectivo aleatorio.

PURPOSE: We compare the contrast sensitivity and visual acuity obtained with an anterior surface modified prolate intraocular lens (Tecnis Z9000) with the contrast sensitivity and visual acuity obtained with a standard acrylic foldable intraocular lens (Acrysof SA60 AT). METHODS: In this prospective trial, 64 patients presenting for cataract surgery were randomized to receive in both eyes either the Tecnis Z9000 intraocular lens or the the Acrysof SA60AT intraocular lens: 32 Tecnis Z9000 and 32 Acrysof SA60AT. Visual acuity and contrast sensitivity were monocular and binocularly tested in all of them preoperatively and three months after surgery. RESULTS: The Tecnis Z9000 intraocular lens provided statistically significantly better monocular (Tecnis group: 0.85; Acrysof group: 0.78; p < 0.01) and binocular (Tecnis group: 0.95; Acrysof group: 0.86; p < 0.02) visual acuity. The contrast sensitivity mean was also greater in Tecnis group in monocular and binocular conditions, but without statistical signification. CONCLUSION: Visual acuity and contrast sensitivity after cataract surgery improved in both groups. But monocular and binocular visual acuity was statistically significantly better only in Tecnis group. The contrast sensitivity mean values were greater in Tecnis group but without statistically significant differences.
