Alteraciones anatomofuncionales en la coriorretinopatía serosa central aguda, detectadas por tomografía de coherencia óptica y microperimetría Anatomical and functional alterations detected by optical coherence tomography and microperimetry in the acute central serose chorioretinopathy
Abstract
OBJETIVO: Determinar las alteraciones anatómicas y funcionales retinales en pacientes con coriorretinopatía serosa central aguda y su repercusión en los resultados visuales. MÉTODOS: Estudio observacional, transversal de 24 ojos con coriorretinopatía serosa central aguda, unilateral. Se realizó, Snellen, microperimetría y tomografía de coherencia óptica, y se calculó el grosor macular central. RESULTADOS: La agudeza visual mejor corregida media fue 0,5. Se encontró desprendimiento seroso neurosensorial en el 100 % de los casos y desprendimiento del epitelio pigmentario en el 29,8 %. El grosor retinal promedio por tomografía de coherencia óptica, fue 388,2 ± 112 µm. La sensibilidad macular total promedio de 11,9 ±5,2 dB, con una sensibilidad macular central (2º) de 10,9 ± 4,87 dB, no se encontró diferencias significativas entre ellas (p= 0,23). Existió correlación inversa entre la sensibilidad central y el grosor macular (r = -0,76), lo que estadísticamente es significativo (p OBJECTIVE: To determine the functional and anatomical alterations of the retina in patients with acute central serous chorioretinopathy. METHODS: Cross-sectional observational study of 24 eyes (24 patients) with acute unilateral central serous chorioretinopathy. Snelle´s chart, microperimetry and optical coherence tomography was used and the central macular thickness was estimated. RESULTS: The best average corrected visual acuity was 0.5. All the cases presented with neurosensoral serous detachment and pigmentary epithelium detachment was found in 29.8%. The average retinal thickness according to the optical coherence tomography figures was 388.2 ± 112 µm. The average total macular sensitivity was 11.9 ± 5.2 dB, with central macular sensitivity (2o) of 10.9 ± 4.87 dB. There were no significant differences between them (p= 0.23). Central sensitivity and macular thickness were inversely correlated (r=-0.76), which is statistically significant; however, this did not occur in the correlation between the total macular sensitivity and the macular thickness (r = -0.68). The location of fixation was central in 86.9% and predominantly central in 13,1 % of patients .Stable fixation was found in 91.3 % whereas the relatively unstable was present in 8.7 %. CONCLUSIONS: In central acute serous chorioretinopathy, the macular sensitivity is affected and is related with the retinal thickness. Location and stability of the fixation are central and stable in general.
