PURPOSE Episcleral plaque therapy (EPT) is applied in the management of some malignant ocular tumors. A customized configuration of typically 4 to 20 radioactive seeds is fixed in a gold plaque, and the plaque is sutured to the scleral surface corresponding to the basis of the intraocular tumor, allowing for a localized radiation dose delivery to the tumor.(More)
PURPOSE To investigate whether shortening the duration of face-down positioning from 1 week to 3 days affects the anatomical success rate of macular hole surgery. METHODS A total of 53 consecutive eyes in 50 patients with full thickness macular holes of 2-24 months' (average 10 months) duration were included in the study. In 20 eyes (37.7%) the hole had(More)
PURPOSE To investigate whether different procedures of topical medication interfere with postoperative face-down positioning and thereby influence the anatomical success rate of macular hole surgery. METHODS A total of 39 consecutive eyes with macular holes were operated with vitrectomy and fluid-gas exchange, followed by face-down positioning for 1 week.(More)
PURPOSE To examine the incidence, the preoperative findings and the surgical outcome of patients presenting with simultaneous, bilateral retinal detachment. METHODS A retrospective analysis of the medical records of patients undergoing surgery for rhegmatogenous retinal detachment between 1990 and 1998. RESULTS During this period a total of 827(More)
PURPOSE We have previously shown that photopic cone b-wave implicit time ≥ 35.0 ms in 30 Hz flicker electroretinography (ERG) predicts ocular neovascularization (NV) in central retinal vein occlusion (CRVO). Here, we evaluate the effects of early panretinal photocoagulation (PRP) in patients with ERG-verified ischaemic CRVO. METHODS Patients with CRVO,(More)
PURPOSE To study the incidence, clinical findings, and tumour characteristics of posterior uveal melanoma in Western Norway, and to report the results of a consistent treatment strategy (I-125 brachytherapy or primary enucleation) over a 13-year period. METHODS The clinical records of all patients with posterior uveal melanoma referred between January(More)
PURPOSE We determined whether combining low dose bacillus Calmette-Guerin (BCG) interferon-alpha 2B would be effective for patients in whom previous BCG failed. MATERIALS AND METHODS A total of 40 patients in whom 1 (19) or more (21) previous induction courses of BCG failed received 6 to 8 weekly treatments of 1/3 dose (27 mg.) BCG plus 50 million units(More)

A 26-year-old man with juvenile glaucoma developed persisting hypotonic retinopathy after trabeculotomy ab externo. An unintended cyclodialysis cleft at the site of the trabeculotomy was suspected, but visualization of the chamber angle was impossible due to a shallow anterior chamber. Seven months after the trabeculotomy the patient was treated with(More)
PURPOSE To visualize the suprachoroidal space and to study the morphology of possible uveoscleral drainage routes in the human eye. METHODS Indian ink stained gelatine was injected directly into the suprachoroidal space of 7 human donor eyes. Those quadrants where gelatine appeared in the episcleral venous network were cut in their entirety in consecutive(More)
