We have performed retinal fluorescein angiography and audiometry in 32 familial and 7 sporadic cases of facioscapulohumeral muscular dystrophy. A mild to moderate retinal vasculopathy, consisting of retinal teleangiectasis and microaneursyms, was present in 18 of 37 evaluable angiograms (49%); 5 patients had minimal changes and 14 angiograms (38%) were(More)
PURPOSE Steady state tear turnover (TTO), defined as TTO under normal physiological conditions, is significantly lower in patients with untreated glaucoma than in healthy control subjects. To obtain more information on the effect of glaucoma on lacrimation, a method for quantification of reflex lacrimation was developed and applied to patients with glaucoma(More)
OBJECTIVE The natural history of non-functioning pituitary macroadenomas (NFMA) has not been completely elucidated. Therefore, we evaluated pituitary function, visual fields, and tumor size during long-term follow-up of non-operated patients with NFMA. DESIGN Follow-up study. PATIENTS Twenty-eight patients (age 55 +/- 3 years) with NFMA, not operated(More)
To assess the effect of glaucoma and timolol on tear secretion, basal tear turnover was measured with fluorophotometry in 13 open-angle glaucoma patients not using any ophthalmic medication, 24 patients using timolol medication daily, and 41 healthy control subjects. Basal tear turnover is defined as the tear turnover at the lowest level of reflex(More)
Epithelial permeability and autofluorescence of the cornea were determined by fluorophotometry in 21 patients with open-angle glaucoma or ocular hypertension using timolol medication with the preservative benzalkonium chloride (BAC) and 2 weeks after changing to timolol medication without BAC. The investigation was performed to determine whether removal of(More)
A follow-up study of 113 patients with suspicious iris nevi who were referred to our clinic between 1973 and 1991 was carried out by: reviewing their clinical records, fluorescein angiography, obtaining recent data with cooperation of their own or the referring ophthalmologist and contacting patients for reexamination. After examination the diagnoses were:(More)
A population based survey on the prevalence of major blinding disorders was conducted in the Wenchi district in central Ghana between March and May 1991. In 10 villages, 1425 people of 30 years and older were screened, using the WHO eye examination record. The prevalence of bilateral blindness above 30 years proved to be 1.7% (best acuity < 3/60): the(More)
AIMS The purpose of this study was to assess whether the preservative benzalkonium chloride (BAC 0.01%) present in timolol induced a decrease in basal tear turnover and a deterioration of precorneal tear film in patients with glaucoma and ocular hypertension using topical timolol. METHODS The basal tear turnover of 20 patients with open angle glaucoma or(More)
Using an enzyme linked immuno-assay (ELISA) and spectrophotometry, we determined levels of secretory IgA and lysozyme in tears of 69 patients with Graves' ophthalmopathy and 28 controls. The quantitative determination of secretory IgA and lysozyme in tears provided an impression of the functioning of the lacrimal gland in the two groups. An IgA/lysozyme(More)
