Introduction: Papillophlebitis is a rare condition characterized by venous congestion and optic disc edema, which has been suggested to occur as a consequence of inflammation of the retinal veins or, possibly, the capillaries of the optic disc, leading to venous insufficiency and compression of the central retina vein. The disease affects healthy young adults and commonly has a benign course, however, if complications such as macular edema or ischemia appears, treatment should be instituted immediately to avoid poor prognosis. Case report: A 40-year old white male patient consulted for a slight decrease in the sensitivity of the visual field in his left eye (OS). Visual acuities (VA) were 20/20 in both eyes. OS fundus examination showed dilated and tortuous retinal vessels, disc edema, and retinal hemorrhages. The patient was diagnosed with papillophlebitis. OS VA decreased to 20/200 due to macular edema, and he was treated with a intravitreal dexamethasone implant. An exhaustive and interdisciplinary exploration process was performed, identifying a recent disease and recovery of Covid-19 as the only factor of inflammation and coagulation alteration. Other systemic diseases were excluded. We also describe a rapid decrease in disc and macular edema after intravitreal dexametasone injection, which could support the inflammatory hypothesis. Conclusion: The importance of this case lies in the possible association of papillophlebitis with the new Covid-19 disease. We believe that the inflammatory reaction and the coagulation alteration present in our patient due to Sars-Cov2 coronavirus may have acted as risk factors for the development of papillophlebitis.

Objective: To assess possible differences in the retinal nerve fiber layer (RNFL) thickness between children with strabismus and controls. This study also compared esotropia with exotropia cases, and dominant eyes with non-dominant eyes. Method: 31 children with esotropia, 17 children with exotropia and 32 controls were studied. The peripapillary RNFL average thickness was determined in 4 different areas (inferior, superior, nasal and temporal) using optical coherence tomography. Statistical analysis was performed a) between the strabic children and the control group, b) between the esotropia and exotropia groups, and c) between the dominant eyes and the non-dominant eyes of the strabic children. Results: No statistically significant differences in RNFL thickness were found in any of these statistical comparisons. Conclusions: From this study, no evidence of changes in RNFL thickness, associated to the existence ARTICLE RESUMEN Objetivo: Comprobar si existen diferencias en el grosor de la capa de fibras nerviosas de la retina (CFNR) entre niños estrábicos y niños con visión binocular normal. Estas diferencias también se estudiaron entre niños con endotropía y exotropía y entre los ojos dominantes y no dominantes de niños estrábicos. Método: Se incluyeron 31 niños con endotropía, 17 con exotropía y 32 niños controles. Se midió la CFNR peripapilar de ambos ojos mediante tomó-grafo óptico de coherencia, obteniéndose los grosores en 4 sectores: superior (S), inferior (I), nasal (N) y temporal (T). Se determinó estadísticamente (p<0,05) si existían diferencias de dichos grosores en los siguientes supuestos: a) entre los niños con estrabismo y los niños controles b) entre los niños con endotropía y exotropía c) entre los ojos dominantes y los no dominantes de los niños estrábicos. Resultados: En ninguna de las comparaciones realizadas, ya sea considerando la totalidad de ojos o 22 ARCH SOC ESP OFTALMOL 2006; 81: 21-26 RECHE-SAINZ JA, et al.
