ABSTRACT
OBJETIVO: Describir una técnica rápida para medir el ángulo papila-fóvea (APF), determinar sus valores normales y su relevancia a la hora de analizar retinografías apareadas. MÉTODOS: En 20 sujetos se realizaron 440 retinografías (3 D OCT-2000, Topcon Corporation, Tokio, Japón) en 11 posiciones diferentes de la cabeza (cervical range of motion [CROM], Performance Attainment Associates). Se analizó el APF mediante el programa Keynote v.6.2.2 y se estudió la reproducibilidad y correlación entre los retinógrafos 3 D OCT-2000 y TRC-50EX (Topcon Corporation, Tokio, Japón). RESULTADOS: La media del APF en el ojo derecho (OD) y en el ojo izquierdo (OI) fue de 5,5 ± 3,4° y de 8,6 ± 2,9°, con una diferencia de 3,1° (p = 0,001 test del signo-rango de Wilcoxon). La media de la diferencia absoluta del APF entre ambos ojos fue de 3,5 ± 2,6°; aumentando con la inclinación cefálica en el plano frontal (p = 0,000 test del signo-rango de Wilcoxon). La media de la suma del APF de ambos ojos fue de 14,1 ± 5,4°. La media de la torsión ocular compensatoria (TOC) con la cabeza inclinada 20 y 40° a la derecha fue de 7,1 y 12,2° en el OD y de 7,7 y 12,1° en el OI. Con la cabeza inclinada 20 y 40° a la izquierda, la media fue de 4,4 y 8° en el OD y de 4,2 y 8,7° en el OI (p = 0,000 test del signo-rango de Wilcoxon). Los retinógrafos mostraron alta correlación y reproducibilidad. CONCLUSIÓN: Nuestra técnica es rápida y reproducible. El OI muestra mayor APF que el OD. La TOC solo ocurre en el plano frontal. Estos aspectos son relevantes al analizar retinografías apareadas
PURPOSE: Describe a time-sparing technique to measure disc-foveal angle (DFA), determine normal values and its role when analyzing paired fundus photographs. METHODS: DFA was analysed using the software program Keynote v.6.2.2 on 440 fundus photographs (3 D OCT 2000, Topcon Corporation, Tokio, Japan) of 20 individuals. The 11 different head positions were determined with the cervical range of motion device (CROM, Performance Attainment Associates). A reproducibility and correlation study between two fundus cameras (OCT 3 D-2000 and TRC-50EX, Topcon Corporation, Tokio, Japan) was performed. RESULTS: Mean DFA of the right and left eye was 5.5 ± 3.4° and 8.6 ± 2.9°, with a difference of 3.1° (P = 0.001 Wilcoxon signed-rank test) in the upright head position. Mean absolute difference in DFA between eyes was 3.5 ± 2.6°; an increase was seen with increasing head tilt (p = 0.000 Wilcoxon signed-rank test). Mean sum of DFA in both eyes was 14.1 ± 5.4°. On head-tilt of 20° and 40° to the right, mean ocular counterrolling (OCR) was 7.1° and 12.2° in the right eye and 7.7° and 12.1° in the left eye. On head-tilt of 20° and 40° to the left, OCR was 4.4° and 8° in the right eye and 4.2° and 8.7° in the left eye (P = 0.000 Wilcoxon signed-rank test). The two cameras showed strong correlation and high reproducibility. CONCLUSIONS: Our DFA measurement technique is time-sparing and reproducible. Left eye shows higher DFA than right eye. OCR occurs only in the roll plane. This information is of value when analyzing paired fundus photographs

OBJETIVO: Revisar y actualizar la bibliografía existente sobre las anomalías congénitas y del desarrollo del nervio óptico. MÉTODOS: Se ha realizado una búsqueda exhaustiva de la bibliografía en las principales bases de datos biomédicas. RESULTADOS: Los pacientes suelen presentarse en la infancia con baja visión. Los defectos de refracción son frecuentes y algunas de ellas pueden desarrollar un desprendimiento de retina seroso. Sobre todo, es imprescindible realizar un correcto diagnóstico diferencial dado que algunas asocian malformaciones del sistema nervioso central, mientras que otras se presentan asociadas a malformaciones sistémicas. CONCLUSIONES: Las anomalías congénitas del nervio óptico incluyen un grupo heterogéneo de entidades con unas características oftalmoscópicas singulares y asociaciones sistémicas frecuentes. Un diagnóstico correcto permitirá solicitar las exploraciones complementarias necesarias e indicar un seguimiento adecuado a estos pacientes
OBJECTIVE: To update the current knowledge about congenital optic disc anomalies. METHODS: A comprehensive literature search was performed in the major biomedical databases. RESULTS: Patients with these anomalies usually have poor vision in infancy. Refractive errors are common, and serous retinal detachment may develop in some of these anomalies. It is critically important to clinically differentiate between these congenital optic disc anomalies, as central nervous system malformations are common in some, whereas others may be associated with systemic anomalies. CONCLUSIONS: Congenital optic disc anomalies are a heterogeneous group of pathologies with characteristic fundus appearance and systemic associations. We should always try to make a correct diagnosis, in order to ask for specific tests, as well as to provide an adequate follow-up

OBJECTIVE: To prepare a protocol for the treatment of retinopathy of prematurity (ROP) agreed by the majority of Spanish ophthalmologists dedicated to this topic. MATERIAL AND METHOD: A draft of the protocol was produced taking into account the experience of the participants and up to date publications. This draft was corrected by all the ophthalmologists participating in the project, and the final document was agreed by all of them. RESULTS: We present general guidelines as an aid for the treatment of ROP, including treatment criteria, treatment methods, a calendar of action, and follow-up. CONCLUSIONS: It is important to have a common working protocol for the treatment of ROP to improve care and to avoid mistakes. Although individual Hospitals may adapt the protocol to their daily activity, it is recommended that there is a minimal working protocol agreed by most of professionals dedicated to pediatric ophthalmology in Spain.

OBJECTIVE: The aim of this study was to evaluate the incidence, severity and outcome of retinopathy of prematurity (ROP) in neonates with birth weights of less than 1,501 g in our environment. METHODS: A prospective study of infants with birth weights of less than 1,501 g was performed from January 1999 to June 2000. One hundred seventy-eight infants were enrolled in the study. Mean gestational age was 29.8 2.9 weeks and mean birth weight was 1,095 261.5 g. RESULTS: Overall, 52 infants (29.2 %) developed ROP, of which 10 (5.6 %) presented threshold ROP requiring treatment. None of the infants with a gestational age of more than 30 weeks and a birth weight of more than 1,250 g presented severe retinopathy. CONCLUSIONS: The incidence found in the present study is similar to that of other studies. Immaturity is the most significant risk factors for the development of ROP. The results of our study led us to change our screening program to detect all threshold ROP.

Objetivo: Determinar la incidencia, gravedad y evolución de la retinopatía del prematuro en recién nacidos con peso inferior a 1.501 g en nuestro medio. Métodos Se ha efectuado un estudio prospectivo de los recién nacidos de peso inferior a 1.501 g entre enero de 1999 y junio de 2000. Se han incluido en el estudio 178 pacientes con una edad gestacional media de 29,8 2,9 semanas y peso medio de 1.095 261,5 g. Resultados Desarrollaron retinopatía el 29,2 per cent de los recién nacidos, de los cuales 5,6 per cent presentaron una retinopatía en estadio umbral y precisaron tratamiento. Ningún paciente de más de 30 semanas o más de 1.250 g presentó una retinopatía grave. Conclusiones La incidencia es similar a la publicada en la literatura, y la inmadurez es el principal factor de riesgo de desarrollar la retinopatía. Los resultados del estudio nos ha hecho variar el programa de cribado para detectar todos los prematuros con retinopatía del prematuro en estadio umbral (AU)
