Non-Simultaneous Bilateral Ischemic Optic Neuropathy Related to High Altitude and Airplane Flight in a Patient with Cerebral Small Vessel Disease.

Non-arteritic anterior ischemic optic neuropathy (NA-AION) is considered the most frequent type of acute optic neuropathy. A 61-year-old woman presented with a NA-AION in her right eye within 24 h following an airplane flight. One year later, after driving for 10 days with a daily accumulated altitude of 1500 m, she developed a NA-AION in her left eye. Systemic disorders were investigated, and cerebral small vessel disease was observed via cranial computed tomography. An inadequate response to hypoxia, in a patient with individual susceptibility, could lead to reduced blood supply to the optic nerve head, which could represent an underlying cause of NA-AION.

Choroidal Hemangioma Associated with Hepatic Hemangioma: A Case Report and Literature Review.

Circumscribed choroidal hemangioma (CCH) is a rare congenital ocular tumor type that is usually benign and asymptomatic. CCH has only been reported once previously in the literature in association with a visceral neoplasm. Here, we present a newly described association between CCH and hepatic hemangioma (HH). We report the case of a 57-year-old woman diagnosed with asymptomatic HHs who presented with a 2- to 3-month history of central scotoma and blurred vision in her left eye. Assessment identified an orange-red elevated lesion with a central serous retinal detachment and subretinal edema. Complementary tests suggested a CCH. To our knowledge, CCH has only been reported once previously in association with a visceral neoplasm, making this newly described association between CCH and HH of clinical relevance. Ophthalmologists should be aware of the possible association between CCH and other visceral tumors as this association offers an opportunity for the early detection of this pathology.

Retinosis pigmentaria inversa a propósito de un nuevo caso / Inverse retinitis pigmentosa a propos of a new case

La retinosis pigmentaria (RP) inversa es una rara degeneración tapetorretiniana que destruye los fotorreceptores del polo posterior del ojos., conduciendo a una importante disminución de la agudeza visual y a escotoma centrales o paracentrales. Como en la forma clásica de RP, los pacientes quejan ceguera nocturna y alteración de la percepción cromática, pero conservan la visión periférica. Desde su descripción en 1876, sólo se han publicado unas pocas docenas de pacientes afectos de RP. Presentamos un nuevo caso correspondiente a un a mujer de 38 años de edad, que no fue remitida a un estadio avanzado de la enfermedad, que no presentaba antecedentes familiares ni se pudo objetivar mutación génica alguna. Se hace hincapié en el diagnóstico diferencial del proceso y se apuntan algunas esperanzadoras terapias experimentales.
