PURPOSE To investigate the efficacy of intravitreal injection of anti-vascular endothelial growth factor agents for Stage 4 retinopathy of prematurity. METHODS Retrospective case series study. The medical records of patients receiving intravitreal injection of anti-vascular endothelial growth factor agents for Stage 4 retinopathy of prematurity from(More)
PURPOSE Our aim was to observe the transient hyperopia during the intense glucose reduction in patients with newly diagnosed diabetes and severe hyperglycemia. STUDY DESIGN Consecutive cases were observed. RESULTS Totally 4 men and 1 woman with a mean age of 48 years were enrolled. In the 4 patients who received insulin, the hyperopia developed at 4.2(More)
Ciliary neurotrophic factor (CNTF) is known as an important factor in the regulation of retinal cell growth. We used both recombinant CNTF and an adenovirus carrying the CNTF gene to regulate retinal photoreceptor expression in a retinal degenerative animal, Royal College of Surgeons (RCS) rats. Cells in the outer nuclear layer of the retinae from(More)
Retinal transplantation aims to restore vision for patients suffering from retinitis pigmentosa and age-related macular degeneration. Because the retinal sheets are fragile in nature, it is difficult to maintain graft integrity during surgical manipulation and after transplantation. In the present work, we report the feasibility of applying sandwich-like(More)
Neural retinal transplantation has great potential for the alleviation of different degenerative and hereditary retinal disorders. However, because of the fragile and soft nature of retina, retinal-sheet transplantation is relatively difficult to achieve. To overcome this difficulty, we developed a technique for lamellar tissue transplantation.(More)
BACKGROUND Visual disturbances after high-altitude exposure were first reported in 1969. Manifestations may include retinal hemorrhage, papilledema, and vitreous hemorrhage. METHODS We observed a group of 6 experienced climbers who ascended Mt Aconcagua to an altitude of 6,962 m in February 2007. Visual acuity study, intraocular pressure study, visual(More)
Newborn screening for Fabry disease in Taiwan Chinese has revealed a high incidence of the late-onset GLA mutation IVS4 + 919G→A (∼1 in 1,500-1,600 males). We studied 94 adults with this mutation [22 men, 72 women; mean age: men 57.8 ± 6.0 (range 42-68), women 39.1 ± 14.1 years (range 19-82)]. Plasma α-galactosidase A activity assay was 10.4 ± 11.2% of(More)
PURPOSE Granulocyte colony-stimulating factor (G-CSF) has been applied clinically for several years. In this study, we used G-CSF to induce the mobilization of hematopoietic progenitor cells into peripheral blood in an ischemia-induced retinal degeneration model. METHODS Male Sprague-Dawley rats received G-CSF treatment for 5 days following optic(More)
Ocular ischemic syndrome (OIS) is characterized by ocular symptoms and signs that are secondary to severe carotid artery obstruction. We report a 69-year-old man who suffered from progressively blurred vision in both eyes. Fundus examination showed scattered areas of retinal hemorrhage, some with a white center, in both eyes. Fluorescence angiography(More)
