Injection of gas into the eye, followed by face-down positioning, is a common protocol for the reseating of the retina in posterior and superior retinal tears and breaks. The physical mechanism by which injected gas helps reattach retinal flaps is often ascribed to the 'buoyancy' force of the injected gas bubble. The various forces at play in this system (surface tension and buoyancy) were calc...

Purpose. To compare three 360°-laser retinopexy (LRP) approaches (using navigated pattern laser system, single-spot slit-lamp (SL) laser delivery, and single-spot indirect ophthalmoscope (IO) laser delivery) in regard to procedure duration, procedural pain score, technical difficulties, and the ability to achieve surgical goals. Material and Methods. Eighty-six rhegmatogenous retinal detachment...

Choroidal metastasis is the most common type of intraocular tumor in adults, and in females the most common primary site is the breast. We report a case of unilateral choroidal metastasis with exudative retinal detachment as the initial presentation of recurrent breast cancer, and subsequent ophthalmic metastasis following diagnostic vitrectomy. A 49-year-old woman with a 7-year-history of well...

PURPOSE To evaluate the outcome after buckle removal in a consecutive series of treated detachments. METHODS Segmental and/or encircling buckles were removed in 46 consecutive patients operated upon for rhegmatogenous retinal detachment, showing buckle extrusion, recurrent pain, and diplopia. Patients underwent a preoperative retinal examination, and a six- months postoperative follow-up. R...
