PURPOSE To map the colour contrast sensitivity (CCS) and possible elevations of colour contrast thresholds in Swedish ophthalmologists operating argon lasers. MATERIAL AND METHODS CCS was measured by a computer and colour monitor system developed by Arden and co-workers. CCS of 58 Swedish ophthalmologists, all users of argon laser, was compared to 26 age-matched controls. The ophthalmologists...

Rhinoscleroma is a chronic progressive granulomatous condition due to Klebsiella rhinoscleromatis.' In severe cases the typical nodular lesions may extend from the nasopharynx into the respiratory tract and be refractory to antibiotics. We are currently investigating the use of laser treatment for lesions in the trachea and major bronchi.2 Such treatment is applicable to benign and malignant le...

Eighty-four eyes received 107 argon laser trabeculoplasty treatments at Beth Israel Medical Center between 1982 and 1984 for advanced primary and secondary glaucoma. The prelaser mean pressure was 20.25 mmHg. Pressures taken 1 1/2 hours postoperatively varied widely: the pressure rose after 47 treatments and fell or remained the same after 60. Significant increases in pressure occurred in 10 ey...

Sixty-three cases of vascularised lipid keratopathy were treated with the argon laser to occlude feeder vessels which had been identified by fluorescein angiography. There was a reduction in extent in 62% and density in 49%. Visual acuity was improved in 48%. Six patients had keratoplasties shortly after treatment, none of which showed graft rejection. Minor complications included temporary hae...

Pediatric Dentistry – 21:2, 1999 Pulpotomy is the treatment of choice for cariously exposed pulps in vital primary teeth. With some modification, the formocresol pulpotomy continues to be used in clinical practice. In an effort to find a more biologically acceptable and effective alternative to formocresol, other agents and techniques have been examined. Non-pharmacologic hemostatic techniques ...
