Vitreous surgery using an internal tamponading agent and chorioretinal adhesion is commonly used to repair retinal detachment associated with choroidal coloboma. The detachment may, however, recur if fluid continues to leak through a retinal defect in the area of the coloboma, despite internal tamponade. We present a case in which a recurrent retinal(More)
We describe the surgical excision of submacular scar in end-stage age-related macular degeneration and transplantation of autologous and homologous retinal pigment epithelial (RPE) cells. The technique involves the preparation of a large retinal flap encompassing the macula and the arcades, removal of the submacular scar, and replacement of the RPE cells,(More)
BACKGROUND Suprachoroidal hemorrhage may cause the expulsion of intraocular contents. Generally, cases of nonexpulsive suprachoroidal hemorrhage have a better outcome than their expulsive counterparts. Those cases with massive nonexpulsive suprachoroidal hemorrhage do better with treatment than without. Treatment modalities have included suprachoroidal(More)
We used tissue plasminogen activator (tPA) to aid in the surgical evacuation of subretinal hemorrhages. Subretinal hemorrhage secondary to a ruptured retinal macroaneurysm was treated in two patients. The surgical technique involved using a micropipette to fashion a small retinotomy through which tPA was injected into the subretinal space and through which(More)
Fifteen eyes with complicated retinal detachments--11 with proliferative vitreoretinopathy (C3 D3), 2 with posterior segment trauma, and 2 with inflammatory retinopathy--were treated with vitrectomy, membrane peeling, and large posterior retinotomy. All posterior relaxing retinotomies were circumferential, including temporal quadrants in all cases. With a(More)
A case of a 27-year-old white male with acquired immunodeficiency syndrome (AIDS) who had a maxillary sinus tumor with secondary orbital involvement was reported. Marked proptosis and distortion of the globe were present. Biopsy by the Caldwell-Luc approach disclosed an immunoblastic lymphoma of B-cell origin. To the best of our knowledge, this is the first(More)
This investigation of the liquid perfluorocarbon, perfluorophenanthrene (Vitreon), establishes its safety and efficacy as a short-term vitreoretinal tamponade. We utilised Vitreon as an intraoperative tool and postoperative vitreoretinal tamponade in 16 patients. Proliferative vitreoretinopathy (PVR) (six), giant retinal tear (four), rhegmatogenous retinal(More)
The authors report the successful repair of a retinal detachment following Cardona prosthokeratoplasty. The surgical technique included pars plana vitrectomy, endolaser photocoagulation, peripheral cryopexy, scleral buckling, and the use of a liquid perfluorocarbon derivative, perfluorophenanthrene, to achieve and maintain reattachment.(More)
Local excision of uveal melanoma is an intriguing therapeutic modality in selected cases. An internal choroidectomy under a retinal flap has been developed as an alternative to retinochoroidectomy in managing posterior pole melanomas. This technique offers more adequate preservation of retinal architecture, thus potentially enhancing central visual function(More)
We evaluated a new liquid perfluorocarbon, perfluorophenanthrene (Vitreon). This material has proven to be non-toxic in vitrectomised rabbit eyes for up to six weeks. Present investigation under FDA guidelines establishes both the safety and efficacy of Vitreon in human eyes. We used Vitreon for intraoperative hydrokinetic retinal manipulation in 15(More)
