BACKGROUND A case of Sweet syndrome mimicking orbital cellulitis is reported. CASE A 17-year-old girl presented with painful eyelid swelling, limited ocular movement in the right eye, and an increased white cell count. The patient was initially diagnosed as having infectious orbital cellulitis, but her symptoms did not improve with administration of(More)
PURPOSE We evaluated the capability of ultrasound biomicroscopy (UBM) to predict fibrovascular proliferation at sclerotomy sites in eyes with postoperative vitreous hemorrhage due to proliferative diabetic retinopathy (PDR). METHODS Ultrasound biomicroscopy was used for examining the sclerotomy sites in 13 eyes of 11 patients with PDR experiencing(More)
Some evidence suggests that the primary locus of the lesion in Leber's hereditary optic neuropathy (LHON) may be intraocular rather than retrobulbar. To clarify this issue, the condition of the retrobulbar portion of the optic nerve was evaluated in patients with the acute stage of LHON. High resolution MRI with fast spin echo sequences of the optic nerve(More)
PURPOSE To investigate long-term complications of hydrogel buckles used in scleral buckling surgery for retinal detachment. METHODS Clinical records of 31 patients who underwent scleral buckle removal between April 1998 and April 2001 were reviewed. Removed buckles were examined by scanning electron microscopy (SEM). RESULTS Nineteen patients were men(More)
OBJECTIVE To evaluate the orbital portion of the optic nerve and the subarachnoid space using fast spin-echo magnetic resonance imaging in normal subjects and in patients with papilledema or optic atrophy. DESIGN Measurements of the optic nerve complex on coronal images were made using high-resolution magnetic resonance imaging with fast spin-echo(More)
To identify risk factors of poor visual outcome with vitrectomy for early-onset endophthalmitis after cataract surgery. Clinical records of 29 consecutive eyes with endophthalmitis developing within 6 weeks after cataract surgery and that underwent therapeutic vitrectomy between June 1996 and April 2001 were retrospectively reviewed. Twenty-two of the eyes(More)
PURPOSE The clinical features and visual prognosis after vitrectomy for endophthalmitis which had developed after cataract surgery were compared in two groups with or without background factors, including malignant tumor, diabetes, oral steroid administration, collagen disease, dacryocystitis, and lid closure disturbance. METHOD Fifty-two patients (53(More)
PURPOSE To investigate whether retina damaged in the process of air/fluid exchange could be visualized in situ using trypan blue staining. METHODS Vitrectomy and air/fluid exchange with continuous air infusion for various periods of time was performed in adult pigmented rabbits, followed by injection of 0.4% trypan blue solution into the vitreous cavity.(More)
