Tamaño del nervio óptico detectado por tomografía coherencia óptica en pacientes sanos atendidos en un centro oftalmológico del Paraguay / Size of the optic nerve detected by optic coherencetomography in healthy patients in an ophthalmologicalcenter of Paraguay

El objetivo de este trabajo fue determinar el tamaño del disco óptico por tomografía de coherencia óptica (TCO), en una población mayor de 40 años, que asistió a control rutinario oftalmológico desde noviembre el 2015 a febrero del 2016 y que no tenían antecedentes conocidos de glaucoma ni de enfermedades sistémicas. Fueron incluidos en el estudio 52 pacientes que asistieron a la consulta externa de oftalmología de la Fundación Visión, por un examen de rutina. Se le diligenció una historia clínica completa, donde se indagaron los antecedentes patológicos tanto sistémicos como oculares. Se realizó la toma de la agudeza visual utilizando la cartilla de Snellen en cada ojo por separado a 6 metros del paciente, refracción automatizada, prueba refractiva, biomicroscopía en lámpara de hendidura con énfasis en la profundidad de la cámara anterior. Se excluyeron pacientes con cámaras anteriores pandas o estrechas (utilización de gonioscopio mirrow 4 mini) y presión intraocular elevada. Luego de la instilación de Tropicamida 0,5%/Fenilefrina HCL 5% en cada ojo y evaluación del polo posterior en lámpara de hendidura con lente de 90D Superfield, se realizó la Tomografía de coherencia óptica con el equipo The ZEISS Cirrus(tm) HD-TCO Model 4000 (Cirrus HD-TCO).

The objective of this study was to determine the size of the optic nerve by opticalcoherence tomography (TCO) in a population older than 40 years old who attendedroutine ophthalmological control from November 2015 to February 2016 and did not haveknown records of glaucoma or systemic. Fifty two patients were included in the study whoatended the external consulting room of ophthalmology of the Foundation Vision for aroutine control. A full medical history was completed, where the systemic and ocularpathologic records were investigated. Visual acuity test was performed using Snellen chartin each patient separately at 6 meters from the patinet. Automatic refraction, retractiontest, slit lamp biomicroscopy with emphasis in the anterior chamber depth were alsoperformed. Patients with narrow or panda anterior chambers (using the mini 4 mirrorgonioscope and high intraocular pressure were excluded. After instillation of tropicamide0.5%/phenylephrine HCL 5% in each eye and evaluation of the posterior pole in slit lampwith 90D Superfield lens, the optic coherence tomography was made using a ZEISSCirrus™ HD-TCO Model 4000 (Cirrus HD-TCO).

Prevalencia de cicatrices retinocoroideas por toxoplasma en una población del Paraguay / Prevalence of toxoplasma retinochoroidal scars in a paraguayan population

El objetivo del trabajo fue determinar la prevalencia de cicatrices retinianas por toxoplasmosis en la población adulta en el municipio de San Francisco de Atyra en Paraguay. Se examinó dicha población desde julio del 2013 hasta marzo 2014, con la participaron en forma voluntaria de 61 familias seleccionadas al azar y dentro de cada una de ellas un integrante mayor de 18 años igualmente seleccionado al azar. Se realizó la toma de la agudeza visual utilizando la cartilla de Snellen en cada ojo por separado a 6 metros del paciente, refracción automatizada, prueba refractiva, biomicroscopía en lámpara de hendidura con énfasis en la profundidad de la cámara anterior de forma inmediata se descartaron pacientes con cámaras anteriores pandas o estrechas (utilización de gonioscopio mirrow 4 mini), presión intraocular, instilación de Tropicamida 0,5%/Fenilefrina HCL 5% en cada ojo, evaluación del polo posterior en lámpara de hendidura con lente de 90D Superfield, oftalmoscopia indirecta con lente de 20D y fotografía en la cámara no midriática. El diagnóstico de toxoplasmosis ocular fue basado en criterios clínicos, y aspectos de la cicatriz de la lesión por retinocoroiditis. Recibieron evaluación oftalmológica 61 pacientes de los cuales 6 pacientes fueron excluidos. La prevalencia de cicatrices corioretininanas fue del 9,1%, siendo más frecuente en hombres sin predilección de edad ni de lateralidad ocular, con agudeza visual igual o mejor a 20/40 con su mejor corrección.

The objective of this study was to determine the prevalence of retinal scars caused bytoxoplasmosis in an adult population from the municipality of San Francisco de Atyra inParaguay. The population of this town was examined from July, 2013 to March 2014.Sixty families, randomly selected, participated voluntarily and within each of them amember older than 18 years of age also selected randomly. Visual acuity was measuredusing the Snellen chart in each eye separately at 6 meters from the patient, as well as theautomated refraction, refraction test, biomicroscopy with a slit lamp with emphasis in thedepth of the anterior chamber. Patients with panda or narrow front chambers (use of amini 4 mirror gonioscope) were discarded. Intraocular pressure, instillation of tropicamide0.5%/phenylephrine HCl 5% in each eye, evaluation of the posterior pole in a slit lampwith 90D Superfield lens, indirect ophtalmoscopy with 20D lenses and photography with non-mydriatic camera were also carried out. The diagnosis of ocular toxoplasmosis wasbased in clinical criteria and aspects of the lesion scar by retinochoroiditis. Sixty onepatients were evaluated ophtalmologically and six were excluded. The prevalence ofchorioretinal scars was 9.1% being more frequent in men without age predominance orocular laterality, with visual acuity equal to or better than 20/40 with its best correction.

Visual acuity and refraction by age for children of three different ethnic groups in Paraguay / Acuidade visual e refração por idade para crianças de três grupos étnicos diferentes no Paraguai

PURPOSE: To characterize refractive errors in Paraguayan children aged 5-16 years and investigate effect of age, gender, and ethnicity. METHODS:The study was conducted at 3 schools that catered to Mennonite, indigenous, and mixed race children. Children were examined for presenting visual acuity, autorefraction with and without cycloplegia, and retinoscopy. Data were analyzed for myopia and hyperopia (SE ≤-1 D or -0.5 D and ≥2 D or ≥3 D) and astigmatism (cylinder ≥1 D). Spherical equivalent (SE) values were calculated from right eye cycloplegic autorefraction data and analyzed using general linear modelling. RESULTS: There were 190, 118, and 168 children of Mennonite, indigenous and mixed race ethnicity, respectively. SE values between right/left eyes were nonsignificant. Mean visual acuity (VA) without correction was better for Mennonites compared to indigenous or mixed race children (right eyes: 0.031, 0.090, and 0.102 logMAR units, respectively; P<0.000001). There were 2 cases of myopia in the Mennonite group (1.2%) and 2 cases in the mixed race group (1.4%) (SE ≤-0.5 D). The prevalence of hyperopia (SE ≥2 D) was 40.6%, 34.2%, and 46.3% for Mennonite, indigenous and mixed race children. Corresponding astigmatism rates were 3.2%, 9.5%, and 12.7%. Females were slightly more hyperopic than males, and the 9-11 years age group was the most hyperopic. Mennonite and mixed race children were more hyperopic than indigenous children. CONCLUSIONS: Paraguayan children were remarkably hyperopic and relatively free of myopia. Differences with regard to gender, age, and ethnicity were small.

OBJETIVO: Caracterizar os erros de refração em crianças paraguaias com idades entre 5 e 16 anos e investigar efeito da idade, gênero e etnia. MÉTODOS: O estudo foi realizado em três escolas que atendiam crianças de etnia Menonita, indígena e mista. As crianças foram examinadas em relação à acuidade visual, autorrefração com e sem cicloplegia, e retinoscopia. Os dados foram analisados ​​para correção de miopia e hipermetropia (EE ≤-1 D ou -0,5D e ≥ 2D ou ≥3 D) e astigmatismo (cilindro ≥1 D). Valores equivalentes esféricos (EE) foram calculados a partir dos dados de autorrefração cicloplegiada do olho direito e analisados ​​por meio de modelagem linear geral. RESULTADOS: Foram avaliadas 190, 118 e 168 crianças de etnias Menonita, indígena e mista, respectivamente. Diferenças entre os valores de EE de olhos direitos e esquerdos não foram significantes. A acuidade visual (AV) sem correção foi melhor para Menonitas em relação às crianças da etnia indígena ou mista (olho direito: 0,031, 0,090 e 0,102 logMAR, respectivamente; P<0,000001). Houve 2 casos de miopia no grupo Menonita (1,2%) e 2 casos no grupo de etnia mista (1,4%) (SE ≤-0,5 D). A prevalência de hipermetropia (SE ≥2 D) foi de 40,6%, 34,2% e 46,3% para as etnias Menonita, indígena e mista. As taxas correspondentes de astigmatismo foram de 3,2%, 9,5% e 12,7%. As mulheres foram ligeiramente mais hipermétropes do que os homens, e o grupo de 9 a 11 anos de idade foi a mais hipermétrope. Crianças da etnia Menonita e mista se mostraram mais hipermétropes do que as crianças indígenas. CONCLUSÕES: As crianças paraguaias são notavelmente hipermétropes e relativamente livres de miopia. Diferenças com relação ao sexo, idade e etnia são pequenas.
