[Acute macular neuroretinopathy: En face OCT description, case series]. / Neurorétinopathie maculaire aiguë : description et intérêt de l'OCT en face, série de cas.

Acute macular neuroretinopathy (AMN) is a rare disease characterized by involvement of the outer retinal layers of the macula. The diagnosis of AMN is based on multimodal imaging, combining infrared reflectance (IR) imaging and optical coherence tomography with B-scan analysis (OCT-B). The en face OCT is a tomographic image processing technique, integrating data from entire A-scans to create a frontal retinal image of the desired area. Structural en face OCT imaging appears to be effective in delineating AMN lesions, using segmentation between the outer plexiform line and the ellipsoid line. In the future, analysis of the various modalities of a single OCT acquisition may be sufficient to diagnose AMN.

[Ocular hypertension and optic neuropathies secondary to dysthyroid orbitopathy: Review of the literature]. / Hypertonie intra-oculaire et neuropathies optiques secondaires à l'orbitopathie dysthyroïdienne : revue de la littérature.

Dysthyroidism, especially Graves' disease, causes potentially severe orbital disease. This is frequently accompanied by ocular hypertension stemming from multiple pathophysiological mechanisms. Adaptations in the technique of intraocular pressure measurement must occur, using portable equipment if necessary. Glaucomatous optic neuropathy secondary to dysthyroid orbitopathy is rare, and screening for signs of compressive optic neuropathy is essential in the case of visual field loss. In cases of secondary glaucomatous optic neuropathy, treatment of the intraocular pressure is based mainly on systemic corticosteroid therapy and topical medications as necessary.

[Metabolic disorders in the gastrectomized patient]. / Estudio de los trastornos metabólicos en el enfermo gastrectomizado.

The present study attempts on one hand to study the metabolic disorders which may present themselves in the gastrectomized patient, such as the malabsorption of fat, vitamin B12, folic acid and iron as well as the possible correlation between steatorrhea and the presence of exocrine pancreatic insufficiency. For this purpose a group of 71 patients have been studied who have undergone a subtotal gastrectomy (70.42%) or total (29.58%) in the General Surgery Services of Elche. The results obtained show the presence of ferropenic or megaloblastic anemia in 61.97% of the group, serious steatorrhea in only 3 patients (4.22%) and calciumphosphorous metabolism alterations appeared in 21.13%. With this we conclude that anemia is the most frequent ferropenic alteration in the gastrectomy patient; steatorrhea does not seem to be produced exclusively by the presence of exocrine pancreatic insufficiency and bone alterations in the gastrectomized patient appear in an insidious manner, being more a question of biochemical alterations than actual clinical lesions.
