Neuroinflammation is involved in the death of retinal ganglion cells (RGCs) after optic nerve injury. The purpose of this study was to determine whether systemic simvastatin can suppress neuroinflammation in the optic nerve and rescue RGCs after the optic nerve is crushed. Simvastatin or its vehicle was given through an osmotic minipump beginning one week(More)
BACKGROUND We report our findings in three cases of unilateral macular edema associated with retinal vein occlusion (RVO) that improved after successful treatment of systemic hypertension alone. METHODS All three cases had systemic hypertension but no diabetes mellitus or other ocular diseases associated with macular edema. All patients were treated only(More)
The purpose of this study was to determine whether inhibition of aquaporin 4 (AQP4) is neuroprotective or neurodestructive after crushing the optic nerve of rats. The left optic nerves of rats were crushed, and TGN-020 (5.0 mg/kg, crush TGN-020) or its vehicle (DMSO, crush placebo) was injected intraperitoneally just after the crushing. As controls, the(More)
BACKGROUND Autoimmune mechanisms have been postulated as a cause of diabetic retinopathy (DR), as several autoantibodies have reportedly been detected in the serum of DR patients. In this present study, we measured serum and vitreous levels of anti-type II collagen (anti-II-C) antibodies in DR patients and investigated their association with the mechanism(More)
BACKGROUND We report a case of traumatic retinal detachment in an eye with severe corneal opacity that was successfully treated using 23 gauge (G) transconjunctival vitrectomy assisted by endoscope and a wide-angle viewing system. CASE PRESENTATION A 22-year-old Japanese man was referred to our hospital with the suspicion of traumatic retinal detachment(More)
INTRODUCTION In this study, we report a case of proliferative diabetic retinopathy in a patient with heparin-induced thrombocytopenia (HIT) in whom vitrectomy was performed with good results. CASE A 57-year-old man presented with a chief complaint of decreased visual acuity (VA) in the left eye. Corrected VA of the left eye was 0.03, and ophthalmic(More)
PURPOSE The purpose of this study was to report a case of Von Hippel-Lindau disease (VHL) with twin retinal capillary hemangiomas that was successfully treated by vitreous surgery for tractional retinal detachment following laser photocoagulation. CASE A 44-year-old male presented at our university hospital after noticing decreased visual acuity in his(More)
BACKGROUND We encountered a rare patient with lens luxation in which the lens had become stuck on the optic disc. Findings obtained during vitreous surgery suggested that the luxated lens had become stuck on the optic disc via residual vitreous gel. CASE PRESENTATION An 88-year-old Japanese man experienced lens luxation into the inferior vitreous cavity(More)
Branch retinal vein occlusion (BRVO) commonly occurs at the arteriovenous crossing in the unilateral eye, and cardiovascular diseases can be risk factors of BRVO. However, the pathomechanism leading to BRVO is not yet clear. In addition to mechanical compression, the vein might locally constrict due to an altered biochemical environment, such as an increase(More)
PURPOSE Retinal arterial macroaneurysm (RAM) has been reported in association with branch retinal vein occlusion (BRVO), and usually BRVO precedes RAM. We present a long-term follow-up case report of unilateral multiple RAMs that developed BRVO following ruptured RAM in the same retinal quadrant. CASE PRESENTATION An 80-year-old woman presented with(More)
