PURPOSE To report 3-year results of the safety and efficacy of canaloplasty, a procedure involving circumferential viscodilation and tensioning of the inner wall of Schlemm canal to treat open-angle glaucoma. SETTING Multicenter surgical sites. DESIGN Nonrandomized multicenter clinical trial. METHODS This study comprised adult open-angle glaucoma(More)
To report 3-year results investigating the safety and efficacy of canaloplasty, a procedure involving circumferential viscodilation of Schlemm’s canal and tensioning of the inner canal wall to treat open-angle glaucoma. This was a prospective, multi-center, interventional study of 109 eyes of 109 adult, open-angle glaucoma patients undergoing canaloplasty(More)
PURPOSE To investigate outcomes after coaxial 1.8 mm microincision cataract surgery combined with 27-gauge vitrectomy (MICVIT) in eyes with vitreoretinal disease and age-related cataract. METHODS A single-center, retrospective case series study of 62 subjects (62 eyes) with a mean age of 70 years who underwent combined microincision phacoemulsification,(More)
PURPOSE To evaluate quality of life (QoL) with a new questionnaire after canaloplasty (CP) and trabeculectomy (TE). PATIENTS AND METHODS We assessed outcomes of surgery, rate of revision surgeries, patients' mood, and influence of postoperative care on QoL, surgery interference with daily activities, and postsurgical complaints. Patients completed the QoL(More)
PURPOSE To evaluate 2-year postsurgical safety and efficacy of canaloplasty (circumferential viscodilation and tensioning of the inner wall of Schlemm canal) to treat open-angle glaucoma (OAG). SETTING Multicenter surgical sites. METHODS This international prospective study comprised adult OAG patients having glaucoma surgery or combined(More)
PURPOSE To study the safety and long-term efficacy of classic viscocanalostomy in patients with open-angle glaucoma (OAG) in different populations. METHODS A total of 726 eyes of 726 patients from Europe or South Africa with primary OAG (POAG) and pseudoexfoliative glaucoma (PXFG) were included in this retrospective multicentre study.

Many ophthalmological disorders are due to poor local microcirculation, examples being central retinal vein occlusion, acute retinal artery occlusion, and ischaemic eye disease. Generalized changes have been found in arterial hypertension, diabetes mellitus, and arteriosclerosis. It is only at a few places that the microcirculation can be investigated(More)
PURPOSE To report 3-year results evaluating the effect on safety and efficacy of canaloplasty to treat open-angle glaucoma when combined with cataract surgery. PATIENTS AND METHODS This was a retrospective subset analysis of a prospective, international, multicenter study evaluating 133 eyes of 133 adult, open-angle glaucoma patients who underwent(More)
To study the impact of hypertension on conjunctival circulation, one group of healthy individuals and three groups of hypertensive patients (different stages of disease) were examined. Each participant had to undergo videomicroscopy to determine erythrocyte velocity in conjunctival capillaries, reactive hyperaemia and the diameter of the erythrocyte column(More)
