PURPOSE Psychophysical methods of measuring macular pigment (MP) use comparisons of short- and midwave light in the fovea and parafovea to derive optical density estimates. This light must pass through the crystalline lens before absorption by the MPs can occur. The effect of lens absorption on these measures has not been adequately determined. The present(More)
Emergent orbital decompression in tense orbital hemorrhage with compromised ophthalmic blood flow may be achieved with lateral canthotomy, defined as incision of the lateral canthal tendon, and cantholysis, defined as canthotomy combined with disinsertion of at least the inferior crus of the lateral canthal tendon. This study was performed to determine(More)
We report herein the concurrent appearance of childhood pemphigus foliaceus and Graves' disease in a 14-year-old girl who was initially seen with crusted and hyperpigmented plaques on her chest, back, abdomen, and legs. The diagnosis of pemphigus foliaceus was confirmed by biopsy and immunofluorescent microscopic studies while the diagnosis of Graves'(More)
We here report the unusual occurrence of bullous pemphigoid mimicking prurigo nodularis in a 59-year-old woman. Direct immunofluorescence studies of a nodular lesion revealed linear deposition of IgG and C3 at the epidermal basement membrane zone (EBMZ). Indirect immunofluorescence studies of serum revealed IgG pemphigoid antibasement membrane zone(More)
PURPOSE To evaluate the physiological effects of hypercapnia on the retrobulbar vasculature in ocular hypertension (OH) and open-angle glaucoma (OAG). METHODS Peak systolic velocity (PSV), end-diastolic velocity (EDV) and resistive index (RI) of the ophthalmic (OA) and central retinal arteries (CRA) were evaluated in 12 eyes with OH and 8 eyes with OAG(More)
Trichiasis is a common condition of multiple etiologies. Cryosurgery has been advocated as an effective means of treatment but may be associated with serious complications, including scar, skin depigmentation, and lid notching. We treated eight consecutive eyelids with the argon laser. At the end of a 3-month follow-up period, no recurrence was noted. The(More)
Diabetics may have an increased susceptibility to cutaneous blister formation clinically manifest as the bullous eruption of diabetes. We evaluated the mechanical force necessary to induce suction blisters in fifteen insulin-dependent diabetics and twenty age-matched normal controls. The mean suction blister threshold for the diabetics was 31.9 minutes(More)
D-Penicillamine is a chelating agent which is effective in the treatment of Wilson's disease, cystinuria, and lead poisoning. In recent years, it has also been used to treat patients with rheumatoid arthritis with good results. The adverse effects of D-penicillamine are many. These include loss of taste, nephrotic syndrome, lupus erythematosus--like(More)
BACKGROUND/AIMS To compare the penetration of levofloxacin, ofloxacin and ciprofloxacin in the aqueous humour of eyes with functioning filtering blebs. METHODS In this investigator-masked study, 48 patients with functioning filtering blebs requiring cataract surgery were randomised into six groups of eight patients. Groups 1, 2 and 3 received topical(More)
Skin necrosis is a rare complication of heparin administration that is usually localized to injection sites. A 32-year-old insulin-dependent diabetic patient, receiving intravenous (IV) and low-dose heparin sodium therapy, had cutaneous necrosis in areas distant to the sites of injection. Prior to the onset of cutaneous lesions, thrombocytopenia develop]ed(More)
