ObjectiveTo observe the imaging features of short-wave length fundus autofluorescence (SW-AF), near-infrared fundus autofluorescence (NIR-AF)and spectral-domain optical coherence tomograph (SD-OCT) in acute central serous chorioretinopathy (CSC). MethodsThis is a retrospective observational consecutive case series study. Eighty-two eyes with acute CSC from 76 patients were enrolled in this study.There were 50 males (56 eyes) and 26 females (26 eyes), average age was (41.32±7.37) years old, average course of the disease was (0.47±1.73) months. The routine clinical examinations included best corrected visual acuity, slit lamp microscope, indirect ophthalmoscope, fundus fluorescein angiography (FFA), SW-AF, NIR-AF and SD-OCT. The imaging features of NIR-AF, SW-AF, SD-OCT and FFA in same eye with acute CSC were analyzed comparatively. ResultsSD-OCT showed retinal pigment epithelium (RPE) detachment corresponding to RPE leakage point on FFA images in all CSC eyes. RPE leakage points in all eyes corresponding to local hypo-NIR-AF, whereas corresponding to normal SW-AF. NIR-AF demonstrated the area of decreased AF corresponding to serous retinal detachment in all eyes, of which, the area of hypo-SW-AF was consistent with that of sensory retinal detachment in 75 eyes. Except for RPE leaking fluorescein in 82 eyes, FFA showed window defects corresponding to clusters of hypo-NIR-AF in 45 eyes, of which, 27 eyes showed hypo-SW-AF appearing concurrently with the locations of window defects of FFA. In 18 eyes, the extent and amount of hypo-SW-AF were less than that of hypo-NIR-AF. ConclusionsThere was local RPE detachment in all eyes with acute CSC. The locations of sensory retinal detachment, local RPE detachment and RPE depigmentation showed hypo-NIR-AF. The locations of sensory retinal detachment and RPE depigmentation showed hypo-SW-AF in most of acute CSC eyes.
Nowadays, one of the most challenging aspects of retinoblastoma (RB) therapy is how to control the resistant or recurrent viable vitreous seeds, for which intravenous chemotherapy appears to be ineffective. Recently, intravitreal chemotherapy offers another option to control advanced stage and vitreous seeds of RB, and may be a promising new approach to RB therapy. However, intravitreal injection for RB patients raises considerable controversy due to concerns of possible extraocular extension along the injection route, and should not replace the primary standard of care for bilateral RB or group E eyes of RB. Close follow-up and further studies are needed to determine appropriate indications, to determine the effective drugs and concentrations, to optimize RB therapy protocols and to investigate the relationship between long-term efficacy and toxicities.
