Computer visual syndrome in graduate students of a private university in Lima, Perú.

BACKGROUND: In recent decades, several studies have found a strong association between prolonged use of video display terminals and ophthalmological symptoms encompassed in the so-called computer visual syndrome (CVS). Few studies have addressed this syndrome in graduate students. METHODS: Observational, cross-sectional descriptive study. A total of 106 postgraduate students were surveyed without ophthalmological pathologies. The diagnosis of CVS was made by means of the questionnaire of Seguí et al. validated in Spanish, which evaluates the frequency and intensity of 16 ocular symptoms. RESULTS: The prevalence of CVS among graduate university students was 62.3% (95% CI: 52.3-71.5). It was found that the highest proportion of students with the syndrome was in the group of older than 40 years old (88.2%) and in the group 21-30 years old (70.0%), showing statistically significant differences (p = 0.004). According to the device and its time of use, students who used the mobile phone for 7-10 h a day showed a higher prevalence of CVS compared to those who used the device for less time (p = 0.030). The business School had the highest prevalence (75.0%). CONCLUSION: Three out of every five graduate students presented CVS with this prevalence being like reported in other populations. There is a need to investigate possible interventions that can help reduce this entity.

Síndrome visual informático en estudiantes universitarios de posgrado de una universidad privada de Lima, Perú / Computer visual syndrome in graduate students of a private university in Lima, Perú

Antecedente En las últimas décadas diversos estudios han encontrado una fuerte asociación entre el uso prolongado de los videoterminales y síntomas oftalmológicos englobados en el denominado síndrome visual informático (SVI). Pocos estudios han abordado este síndrome en estudiantes de posgrado. Métodos Estudio observacional, descriptivo de corte transversal. Se encuestó a 106 estudiantes universitarios de posgrado sin patologías oftalmológicas. El diagnóstico de SVI se realizó mediante el cuestionario de Seguí et al. validado en castellano, el cual evalúa la frecuencia e intensidad de 16 síntomas oculares. Resultados La prevalencia de SVI de los estudiantes universitarios de posgrado fue del 62,3% (IC 95%: 52,3-71,5). Se encontró que la mayor proporción de estudiantes con el síndrome estuvo en el grupo mayor de 40 años (88,2%) y en el grupo de 21-30 años (70,0%), mostrando diferencias estadísticamente significativas (p=0,004). Según el dispositivo y su tiempo de uso se observó que los estudiantes que utilizaban el teléfono móvil de 7 a 10h diarias presentaron una prevalencia de SVI mayor en comparación con quienes utilizaban el dispositivo menos tiempo (p=0,030). La Facultad de Ciencias Empresariales presentó la prevalencia más elevada (75,0%). Conclusión Tres de cada cinco estudiantes universitarios de posgrado presentaron SVI, siendo esta prevalencia similar a lo reportado en otras poblaciones. Es necesario que se investiguen posibles intervenciones que puedan ayudar a reducir esta entidad (AU)

Coristoma óseo epibulbar: caso clínico y revisión de literatura / Epibulbar osseous choristoma: A clinical case and review of the literatura

Presentamos el caso de un preescolar varón de 3 años con un coristoma óseo epibulbar. El paciente presentaba una masa subconjuntival de consistencia dura de 8×10 mm en el cuadrante superotemporal del ojo derecho con vascularización y presencia de cilios largos de aproximadamente 8 a 10 mm que tocaban la superficie corneal. El estudio histopatológico evidenció la presencia de trabéculas de hueso compacto maduro rodeado de tejido fibroso, canales de Havers con anillos concéntricos de hueso laminar sin médula ósea y con osteocitos normales, lo cual definió el diagnóstico de coristoma óseo epibulbar. El coristoma óseo es el tipo más raro de coristomas oculares y debe considerar en el diagnóstico diferencial de los tumores epibulbares pediátricos

We present the case of a 3-year-old male child with an epibulbar bone choristoma. The patient presented with a hard consistency subconjunctival mass of 8 × 10 mm in the superior-temporal quadrant of his right eye along with vascularisation and a long cilium of approximately 8 to 10 mm that touched the corneal surface. The histopathology study showed the presence of trabeculae of mature, compact bone surrounded by fibrous tissue, as well as Havers channels with concentric rings of laminar bone without bone marrow, and with normal osteocytes which defined the diagnosis of epibulbar bone choristoma. Osseous choristoma is the rarest type of the ocular choristoma and should be considered as a differential diagnosis among paediatric epibulbar tumour

Características morfométricas de disco óptico y espesor de capa de fibras nerviosas de la retina mediante tomografía de coherencia óptica Cirrus 5000 en pacientes sanos atendidos en el Instituto Nacional de Oftalmología / Morphometric characteristics of the optical disc and thickness of retinal nerve fibre layer using Cirrus 5000 optical coherence tomography in healthy patients attending the National Institute of Ophthalmology

OBJETIVO: Describir las características morfométricas y espesor de la capa de fibras nerviosas de la retina (CFNR) en pacientes sanos usando la tomografía de coherencia óptica. MÉTODOS: Estudio transversal y descriptivo. Un total de 184 ojos de 184 personas de etnia mestiza fueron inscritos después de una evaluación oftalmológica completa en el Instituto Nacional de Oftalmología, Lima-Perú. Se midieron los parámetros morfométricos del disco óptico y espesor de la CFNR mediante tomografía de coherencia óptica ZEISS CIRRUS(TM) HD-OCT Modelo 5000 (Carl Zeiss Inc., Dublin, CA, EE.UU). Megalopapila fue definida como: área del disco óptico > 2,5 mm2 y área mayor que la media más 2 desviaciones estándar. RESULTADOS: Se obtuvo un área de disco óptico de 2,21 ± 0,43 mm2, anillo neurorretinal de 1,37 ± 0,25 mm2, excavación de 0,84 ± 0,48 mm2; promedio de ratio excavación/disco de 0,58 ± 0,16, ratio excavación/disco vertical de 0,55 ± 0,15 y un espesor de CFNR 100,30 ± 8,54 μm. La prevalencia de megalopapila fue del 24 y 4%, considerando un área de disco > 2,5 mm2 y 3,07 mm2 respectivamente. Al comparar megalopapilas con discos normales, el área del anillo (p = 0,08) y espesor de CFNR (p = 0,73) no mostraron diferencias estadísticamente significativas. CONCLUSIÓN: El área de disco fue 2,21 ± 0,43 mm2 con un espesor de CFNR 100,30±8,54μm. La prevalencia de megalopapila fue del 24 y 4%, considerando un área de disco>2,5mm2 y 3,07mm2 respectivamente. Las megalopapilas y los discos normales son similares en términos de área del anillo y espesor de CFNR

OBJECTIVE: To describe the morphometric characteristics and thickness of the retinal nerve fibre layer (CFNR) in healthy patients using optical coherence tomography. METHODS: A cross-sectional and descriptive study was conducted on a total of 184 eyes of 184 people of mestizo origin enrolled after a complete ophthalmological evaluation at the National Institute of Ophthalmology, Lima-Peru. The morphometric parameters of the optic disc and thickness of the CFNR were measured by optical coherence tomography ZEISS CIRRUS(TM) HD-OCT Model 5000 (Carl Zeiss Inc., Dublin, CA, EE.UU). Megalopapilla was defined as: area of the optical disc greater than 2.5 mm2 and area greater than the mean plus 2 standard deviations. RESULTS: The areas obtained were: optical disc of 2.21 ± 0.43 mm2, neuroretinal ring of 1.37 ± 0.25 mm2, 0.84 ± 0.48 mm2 cup; mean cup/disc ratio of 0.58 ± 0.16, vertical cup/disc ratio of 0.55 ± 0.15, and a CFNR thickness of 100.30 ± 8.54 μm. The prevalence of megalopapilla, being considered as a disc area greater than 2.5 mm2 and 3.07, was 24% and 4%, respectively. When comparing megalopapilla with normal discs, the area of the ring (P = .08) and thickness of CFNR (P = .73) did not show statistically significant differences. CONCLUSION: The mean disc area was 2.21±0.43mm2 with a CFNR thickness of 100.30 ± 8.54 μm. The prevalence of megalopapilla was 24% and 4%, considering a disc area greater than 2.5 mm2 and 3.07 mm2, respectively. These results show that the megalopapilla and normal discs are similar in terms of ring area and CFNR thickness
