AbstractThis study aimed to investigate the relationship between autofluorescence (AF) signal measured with ultra-wide field imaging and visual functions in patients with cone-rod dystrophy (CORD). A retrospective chart review was performed for CORD patients. We performed the visual field test and fundus autofluorescence (FAF) measurement and visualized retinal structures with optical coherence tomography (OCT) on the same day. Using binarised FAF images, we identified a low FAF area ratio (LFAR: low FAF/30°). Relationships between age and logMAR visual acuity (VA), central retinal thickness (CRT), central choroidal thickness (CCT), mean deviation (MD) value, and LFAR were investigated. Thirty-seven eyes of 21 CORD patients (8 men and 13 women) were enrolled. The mean patient age was 49.8 years. LogMAR VA and MD were 0.52 ± 0.47 and − 17.91 ± 10.59 dB, respectively. There was a significant relationship between logMAR VA and MD (p = 0.001). LogMAR VA significantly correlated with CRT (p = 0.006) but not with other parameters. Conversely, univariate analysis suggested a significant relationship between MD and LFAR (p = 0.001). In the multivariate analysis, LFAR was significantly associated with MD (p = 0.002). In conclusion, it is useful to measure the low FAF area in patients with CORD. The AF measurement reflects the visual field deterioration but not VA in CORD.

Photopsia, floaters, visual field defects, loss in visual acuity, periocular pain, and dyschromatopsia are symptoms of rhegmatogenous retinal detachment in which early signs are Weiss ring, pigmented cells in anterior vitreous (tobacco dust sign), a general decrease in intraocular pressure and retinal detachment in a convex configuration. On the other hand, the demarcation line, secondary retinal cysts, and proliferative vitreoretinopathy are some of the late findings of detachment. Imaging of the retina is crucial in rhegmatogenous retinal detachment. Fundus photography, wide-field imaging systems, optical coherence tomography, and fundus autofluorescence tomography are beneficial for documentation and monitoring progression. Ultrasound imaging, computerized tomography, and magnetic resonance imaging may be helpful when the retina cannot be visualized in cases like vitreous hemorrhage and dense cataract. Diagnosis can be made with indirect ophthalmoscopy with indentation, and ultrasound imaging in an opaque medium. Differential diagnosis of rhegmatogenous retinal detachment is exudative and tractional detachment, as well as lesions that can mimic retinal detachment such as retinoschisis, intraretinal macrocysts, choroidal detachment, vitreous opacities and white with or without pressure lesions.
