Non-arteritic anterior ischemic optic neuropathy as the only manifestation of a malignant hypertensive crisis: Report of a case.

Non-arteritic anterior ischemic optic neuropathy (NAION) is after glaucoma the most common optic neuropathy in patients over 50 years. It is known that high blood pressure (HBP) is an important risk factor for the development of NAION. It is also known that malignant arterial hypertension (MAH) could be accompanied by optic disc edema. However, MAH has not classically been considered a cause of NAION. We report the case of a 32-year-old patient who presented irreversible visual loss with a pattern compatible with NAION as the only manifestation of a hypertensive crisis.

Long anterior zonule trait, lessons learned about an uncommon form of secondary angle closure: a case report.

A 62-year-old black woman with uncontrolled chronic narrow-angle glaucoma on 3-drug therapy underwent phaco-non-perforating deep sclerectomy of her left eye. During surgery it was revealed that she had long zonule trait. She later required goniopuncture and conjuntival needling, presenting an iris herniation in the goniopuncture that could be reduced conservatively. Long anterior zonule trait should be suspected in those patients presenting with a combination of narrow angle and pigment dispersion syndrome. The management of ocular hypertension and glaucoma associated to this trait is not protocolized. This communication discusses on the best action in this rare form of glaucoma.

Choroidal neovascularisation associated with optic nerve head drusen: Case report and review of literature. / Neovascularización coroidea asociada a drusas del nervio óptico: caso clínico y revisión de la literatura.

A 21-year-old man was seen for follow-up of optic nerve head drusen (ONHD) in the ophthalmology department. Funduscopy revealed the presence of choroidal neovascularisation (CNV) in the papillomacular bundle of his right eye (RE). The patient was successfully treated with two intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF). Peri-papillary choroidal neovascularisation in papillomacular bundle is a rare complication in patients with ONHD. These forms of CNV show a good response to anti-VEGF treatment.

Which are the colors of the dress? Review of an atypical optic illusion. / ¿De qué colores es el vestido? Revisión de una ilusión óptica atípica.

OBJECTIVE: In 2015 the picture of a dress went viral on social media. A significant proportion of the population saw it as golden and white (G&W), while another significant proportion saw it as blue and black (B&B). The aim of this article is to review the related literature. MATERIAL AND METHODS: Bibliographic search conducted in Pubmed and Google. The algorithm used was: (color OR colour) AND (dress OR #thedress). The search was limited to the years 2015-2017. No language restrictions were used. The references of the located articles were used to widen the search. RESULTS: The search algorithm retrieved 23 articles related to the topic. Most of the works have been published in journals in the field of perception. Most works address the topic from the point of view of chromatic constancy. Genetic factors seem to have a low weight in the way the dress is perceived. There are few studies on the potential influence of ocular factors. CONCLUSION: This illusion has gained little attention in ophthalmology journals. Although colour constancy is certainly involved, there is still no theory available to explain the dichotomous character of this optical illusion.

Traumatic cyclodialysis treated with transscleral ciclodiode laser: Anterior and posterior segment evolution. / Ciclodiálisis traumática tratada con láser ciclodiodo transescleral: evolución de la exploración del segmento anterior y posterior.

CASE REPORT: A 35-year-old man suffered a severe hipotension maculopathy after being kicked in his left eye. He presented a broad area of iridodialisis. Gonioscopy, ultrasound biomicroscopy and optic coherence tomography were not able to locate the suspected cyclodialysis. Medical treatment was ineffective. Five months later the patient received transcleral diode laser cyclophotocoagulation with clinical resolution. DISCUSSION: Transscleral diode laser constitutes an effective treatment, with low iatrogenia, that can solve cases of ocular hypotension, even when the location of the cyclodialysis has not been determined.

[Effectiveness of topical bevacizumab in bilateral primary lipid keratopathy]. / Eficacia de bevacizumab tópico en queratopatía lipoidea bilateral primaria.

CASE REPORT: A 75-year-old man with bilateral idiopathic lipid keratopathy underwent a penetrating keratoplasty in the left eye. One month later, there was deep corneal neovascularisation extending across the bed and the graft-host interface, with a whitish opacity surrounding the vessels. Topical bevacizumab (25mg/mL) was administered 4 times daily for 2 months with partial regression of corneal neovascularization. DISCUSSION: Topical bevacizumab may be useful in preventing a recurrence of lipid deposition after penetrating keratoplasty in patients with bilateral primary lipid keratopathy, although its long-term efficacy needs to be assessed.

[Morphometric analysis of corneal endothelium after intravitreal ranibizumab (Lucentis) in age-related macular degeneration treatment]. / Análisis morfométrico del endotelio corneal tras ranibizumab intravítreo en la degeneración macular asociada a la edad.

PURPOSE: To determine the effect of intravitreal injection of 0.5mg ranibizumab on the corneal endothelium in patients with age-related macular degeneration (AMD). METHODS: Observational, prospective case series pilot study. Twenty-six eyes of 26 consecutive patients with AMD were evaluated. All participants received one monthly intravitreal injections of 0.5mg ranibizumab for three consecutive months. The follow-up period was 6 months. Central corneal specular microscopy was performed before injection and at 7 days and 6 months after the first intravitreal injection. The endothelial cell density, coefficient of variation of cell size, and percentage of hexagonal cells were analyzed and the central corneal thickness was measured. RESULTS: There were no significant differences in the endothelial cell densities, coefficients of variation of cell size and percentages of hexagonal cells before injection and at 7 days and 6 months after the first intravitreal ranibizumab injection (P>0.5). There was also no significant difference in central corneal thickness measurements through the follow-up period (P>0.5). CONCLUSIONS: Repeated intravitreal injections of 0.5mg ranibizumab do not seem to cause substantial changes in the corneal endothelium.

[Management of subretinal hemorrhage with r-TPA, SF-6 and ranibizumab]. / Tratamiento de una hemorragia subretiniana con r-TPA, SF6 y ranibizumab.

CASE REPORT: We present a case of a patient with subretinal hemorrhage treated with intravitreal r-TPA, SF-6 and ranibizumab. DISCUSSION: Subretinal hemorrhages secondary to age-related macular degeneration are associated with poor visual outcome. A wide variety of management approaches has been developed, but the prognosis of these patients has not been modified by any of them. The association of an intravitreal anti VEGF drug to r-TPA and gas, may improve its results as we add the treatment of the subjacent etiology to the pneumatic displacement.

[Primary cerebral lymphoma diagnosed by the ophthalmologist]. / Diagnóstico de linfoma cerebral primario por el oftalmólogo.

CASE REPORT: A 20-year-old male, HIV positive, with myodesopsias (floaters) in both eyes for two weeks. Fundus examination revealed bilateral papillary oedema with peripapilar flame-shaped haemorrhages. The neuroimaging tests showed a cerebral mass in the left parietal lobe. The biopsy confirmed the diagnosis of lymphoid neoplasm. DISCUSSION: Primary lymphoma is the most common malignancy of the central nervous system (CNS) in AIDS patients, although highly active antiretroviral therapy has reduced its incidence. The ophthalmologist plays an essential role in the diagnosis of CNS neoplasm.

[Primary bilateral lipid keratopathy]. / Queratopatía lipoidea primaria bilateral.

CASE REPORT: Observational, case report study. A 45-year-old woman complained of bilateral irritation and photophobia since childhood. Slit-lamp examination revealed yellow-whitish deposits involving the deep stroma of the peripheral half of the cornea in both eyes. The evolution was slowly progressive with a moderate impairment of her visual acuity. DISCUSSION: Lipid deposits adopt symmetric and bilateral configurations; the absence of corneal vascularization and ocular pathology as well as any lipoprotein disorder support the diagnosis of primary lipid keratopathy. The slow progressing disease is also confirmed.

Bilateral non-simultaneous optic neuropathy and unilateral macular edema in a patient with POEMS syndrome.

PURPOSE: To report a case of bilateral non-simultaneous optic neuropathy and unilateral macular edema in a patient with polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. METHODS: A 61-year-old man with POEMS syndrome had bilateral anterior optic neuropathy and unilateral macular edema. RESULTS: Visual field testing showed bilateral superior altitudinal field defect. Fluorescein angiography revealed unilateral pooling of fluid consistent with cystoid macular edema. Optical coherence tomography (OCT) showed bilateral loss of retinal nerve fiber layer thickness. The erythrocyte sedimentation rate and C-reactive protein values were normal. The serum vascular growth factor measurement was elevated. CONCLUSIONS: This is the first reported case of ophthalmoscopic, angiographic, and OCT evidence of non-simultaneous optic neuropathy and macular edema in this syndrome. The increased vascular permeability could explain all these factors.

[Unilateral exophthalmos as the debut of a non-secretory multiple myeloma]. / Exoftalmos unilateral como debut de mieloma múltiple no secretor.

CASE REPORT: A 56 year-old male presented blurred vision and diplopia for 2 months, left unilateral exophthalmos, restricted ocular motility and papilledema. The imaging proofs showed osteolytic lesions in the left sphenoid bone, fourth rib and fourth dorsal vertebral body with associated masses of soft tissues. Biopsy was performed and the diagnosis of plasma cell neoplasm was established. The diagnosis of non-secretory multiple myeloma was made by analytical criteria and bone marrow biopsy. Local radiotherapy and polychemotherapy was prescribed. CONCLUSIONS: The ophthalmologist can play an important role in the diagnosis of systemic neoplasms that require the intervention of a multidisciplinary team.

[Eclipse retinopathy: three case reports]. / Retinopatía por eclipse. A propósito de tres casos.

CASE REPORT: We present the evolution of eclipse retinopathy in 3 patients who came to our hospital after the eclipse of October 2005 and had foveal lesions and visual field alterations. DISCUSSION: Eclipse retinopathy is a maculopathy that occurs after exposure to intense solar radiation, such as occurs during an eclipse, and is produced by a photochemical mechanism. Although the macular changes and symptoms are usually reversible, residual defects at the level of the EPR and scotoma in visual fields can occur. For these reasons the most appropriate treatment is prevention by means of public awareness campaigns.
