Comparable improvements of retinal thickness were observed in the STTA and eye drop groups. Instillation of difluprednate ophthalmic emulsion 0.05% is a safe and effective treatment that does not require surgical intervention and does not produce severe side-effects.

The reddish lesion on ophthalmoscope corresponded to the excavation lesion, detected in the fovea only by OCT; this indicates a new clinical availability of OCT in clinical diagnosis.

. Purpose:  To evaluate the efficacy of treatment of diffuse diabetic macular oedema (DME) with difluprednate ophthalmic emulsion 0.05% (Durezol™) in eyes before vitrectomy. Methods:  This study enrolled patients with diffuse DME for whom more than 3 months had passed since prior treatment. Nineteen eyes in 15 subjects were treated with difluprednate ophthalmic emulsion 0.05% four times daily for the first month and then twice daily for 2 months (treatment group). As a control group, 22 eyes in 11 subjects with DME were selected from subjects who underwent the steroid responder test. Results:  In the treatment group, the mean visual acuity (VA) (±SD) was 0.38 ± 0.25 logMAR and mean retinal thickness was 461.1 ± 109.9 μm at baseline. After 1 month of treatment, the mean VA had improved to 0.29 ± 0.25 (Wilcoxon rank‐sum test, p = 0.30), while mean retinal thickness had decreased to 372.1 ± 70.0 μm (p = 0.006). The rate of effective improvement in retinal thickness was 42% and that of VA was 26%. In the control group, changes in neither VA nor retinal thickness were significant. Conclusions:  Eye drop therapy using difluprednate ophthalmic emulsion 0.05% is a useful and effective treatment modality without surgical intervention or severe side‐effects.

Five eyes of five patients with polypoidal choroidal vasculopathy (PCV) without acute hemorrhagic changes or subretinal proliferative tissue to observe the three-dimensional structures and to demonstrate the nature of these images and their interpretation. The abnormal networks surrounding polypoidal lesions were considered to be abnormal pathological blood vessels. The segmentation analysis of spectral-domain optical coherence tomography (OCT) has revealed the three-dimensional features of polypoidal lesions and surrounding abnormal blood vessel networks beneath retinal pigment epithelium. The changes of pathological findings of PCV were also detected, including the enlargement of hemorrhagic pigment epithelium detachment (PED). The segmentation analysis is useful to observe PCV lesions from the bird's eye view.

We observed tangential fine folds of the ILM. These were detected by using only 3D imaging, and might be useful for investigating the optimal indication of vitrectomy for DME.
