The IOL power calculation with PCI yielded no difference in postoperative refraction errors between the vitreomacular interface disorders. There was no correlation with preoperative refraction, age, or preoperative or postoperative macular thickness.

Purpose: To evaluate the effect of cyanidin-3-glucoside (C3G) in oxygen-induced retinopathy (OIR) mouse model. Methods: In this experimental study, 10 C57BL / 6J type mice exposed to room air comprised two control groups ( n = 5 each; a negative control and a group receiving intravitreal sterile dimethyl sulfoxide [IVS DMSO]). Thirty C57BL / 6J type mice exposed to 75% ± 2% oxygen from postnatal day 7 to postnatal day 12 comprised the OIR groups. On postnatal day 12, these mice were randomized into six groups ( n = 5 each): two OIR control groups (negative control and IVS DMSO), two intravitreal C3G groups (300 and 600 ng/μL), and two intraperitoneal C3G groups (0.05 and 0.1 mg/kg). We quantified neovascularization by counting endothelial cell proliferation on the vitreal side of the inner limiting membrane of the retina and examined histological and ultrastructural changes via light and electron microscopy and apoptosis by terminal deoxynucleotidyl transferase deoxy-UTP-nick end labeling. Results: The intravitreal C3G groups yielded lower endothelial cell counts compared with the intravitreal DMSO group. The intraperitoneal high-dose group had lower cell counts compared with the OIR control groups. Electron microscopy revealed significantly less mitochondrial dysmorphology in intravitreal groups and the high-dose intraperitoneal mice. We noted no difference in apoptotic cell count between the controls, low-dose intravitreal, and both intraperitoneal groups. However, apoptotic cell count was significantly higher in the high-dose intravitreal group. Conclusion: C3G suppresses endothelial cell proliferation in an OIR mouse model, leads to a reduced hyperoxia-induced mitochondrial dysmorphology, but increases apoptotic cell death in high concentrations.

We report a case of optic disc pseudoduplication without pathological myopia. A 79-year-old woman presented with gradually decreased vision. Fundus examination showed macular drusen in both eyes and subretinal haemorrhage in the left eye. Both optic discs appeared to be tilted and the left optic disc was seen to be inferiorly duplicated. Pseudodoubling of the optic discs can be caused by optic disc and peripapillary chorioretinal colobomas and pathological myopia. Considering that our patient did not have enough axial length to merit a diagnosis of pathological myopia and no pathological fundus lesions typical of elongated sclera, we suggest that acquired pseudoduplication is not a condition unique to pathological myopia, but can occur in all myopic patients. The clinical materials, including ophthalmological examination, fundus fluorescent angiography and MRI scan of the orbit, were reported, and its pertinent literatures were reviewed.
