We retrospectively analyzed by life table analysis the visual and functional results in 500 eyes that underwent combined vitrectomy and silicone oil for various types of complicated retinal detachments. The cumulative proportion of eyes with attached retina was 77% at six months postoperatively, with a range of 71% for perforating injuries to 85% for(More)
BACKGROUND Vitreous surgery for Idiopathic macular holes can result in both anatomic closure of the hole and visual improvement. In some patients even normal visual acuity is achieved. Postoperative visual field loss is a newly recognized complication. This prospective study evaluates the frequency and significance of scotomas after vitrectomy with gas(More)
The use of advanced phacoemulsification techniques enables the surgeon to remove opacified lens material while preserving a nearly complete capsular bag. For this reason, several groups are presently working on lens refilling techniques. We have developed a method for the injection of a liquid monomer into the lens capsule. The material can be polymerized(More)
BACKGROUND AND OBJECTIVES Primitive human hematopoietic cells contain higher levels of aldehyde dehydrogenase (ALDH) activity than their terminally differentiating progeny but the particular stages when ALDH levels change have not been well defined. The objective of this study was to compare ALDH levels among the earliest stages of hematopoietic cell(More)
We investigated whether emulsification glaucoma after silicone oil implantation can be influenced positively by removal of the oil. In 16 of 264 patients successfully operated upon with purified silicone oil 5000 cps, we found a glaucoma refractory to medical therapy and probably caused by emulsification. We removed the silicone oil from these eyes and(More)
In spite of advances in surgical technique and the development of purified silicone oils, secondary glaucoma still develops in 10-20% of cases following silicone oil surgery. In the first part of this study it is shown by life-table analysis that factors such as early lens removal, inferior iridectomy, early silicone removal or the use of purified silicone(More)
Endocapsular cataract removal and injection of a liquid artificial lens has several advantages, including restitution of accommodation, small corneoscleral incision, a more physiological position of the intraocular lens, and a reduced rate of secondary opacification. Our technique consists of bimanual phacofragmentation followed by injection of a fluid(More)
A method for the injection of liquid intraocular lenses into the capsular bag would offer many benefits in the treatment of cataracts. The corneoscleral incision could be made even smaller, the lens diaphragm would be conserved more physiologically, and a method of therapy for presbyopia might eventually be possible. As a prerequisite, a method of(More)
Silicone oil as endotamponade in cases with attached retina is only indicated in a few very selected cases. These are cases with a high risk of intravitreal hemorrhage and a need for quick visual rehabilitation. We examined 23 patients, who had undergone pars plana vitrectomy and silicone oil filling. All patients were diabetics with proliferative(More)
