Age-related macular degeneration (AMD) is one retinal aging process that may lead to irreversible vision loss in the elderly. Its pathogenesis remains unclear, but oxidative stress inducing retinal pigment epithelial (RPE) cells damage is perhaps responsible for the aging sequence of retina and may play an important role in macular degeneration. In this(More)
OBJECTIVE The objective of our study was to evaluate the CT characteristics of globe rupture. MATERIALS AND METHODS The medical records of patients seen in the emergency department with blunt, penetrating, or explosive orbit injury were retrospectively reviewed. A total of 75 patients (76 injured globes) were included (56 males and 19 females; average(More)
BACKGROUND AND OBJECTIVE To evaluate the leakage pattern in eyes with idiopathic epiretinal membranes (ERM) using fluorescein angiography (FA) and the structure of the retinal capillary plexus with optical coherence tomography angiography (OCTA). PATIENTS AND METHODS The authors enrolled patients with idiopathic macular ERM in the consecutive case series(More)
BACKGROUND Granular cell tumors are rare neoplasms which can occur in any part of the body. Granular cell tumors of the orbit account for only 3 % of all granular cell tumor cases. Computed tomography and magnetic resonance imaging of the orbit have proven useful for diagnosing orbital tumors. However, the rarity of intraorbital granular cell tumors poses a(More)
PURPOSE To study the effects of translumenal Nd:YAG embolectomy (TYE) on the visual functions of patients presenting with decreased vision (<6/12) and visual field defect (VFD) from embolus-induced branch retinal artery occlusions. METHODS Case reports. RESULTS The initial information available for five Chinese patients consisted of best-corrected(More)
Corneal neovascularization (NV), the excessive ingrowth of blood vessels from conjunctiva into the cornea, is a common sequela of disease insult that can lead to visual impairment. Clinically, topical steroid, argon laser photocoagulation, and subconjunctival injection of bevacizumab have been used to treat corneal NV. Sometimes, the therapies are(More)
The ocular surface is the outermost part of the visual system that faces many extrinsic or intrinsic threats, such as chemical burn, infectious pathogens, thermal injury, Stevens-Johnson syndrome, ocular pemphegoid, and other autoimmune diseases. The cornea plays an important role in conducting light into the eyes and protecting intraocular structures.(More)
BACKGROUND Submacular hemorrhage associated with polypoidal choroidal vasculopathy (PCV) may cause severe visual loss. The purpose of this study is to report the visual prognosis of massive submacular hemorrhage in patients with PCV. METHODS Twenty patients with PCV and submacular hemorrhage who received either subretinal tissue plasminogen activator(More)
BACKGROUND Light injury to photoreceptor cells and retinal pigment epithelium may lead to oxidative stress and irreversible degeneration of retina, especially degeneration of the high energy-demanded macula. The model of retinal photodamage could be applied to age-related macular degeneration and other degenerative retinal diseases for exploring new(More)
BACKGROUND Computed tomography (CT) is known to be the first-line imaging method for patients with or suspect to have intraocular foreign bodies (IOFBs). The purpose of this study is to evaluate clinical outcomes in the management of IOFBs with the aid of CT. METHODS Retrospective chart review of patients who received orbital CT prior to the removal of an(More)
