Occurrence of Macular Neovascularization after Retinal Pigment Epithelium-Choroid Translocation Surgery to Treat Complicated Age-Related Macular Degeneration: Incidence, Management, and Outcome.

Introduction: This study investigates the incidence, clinical characteristics, and treatment response of macular neovascularization (MNV) occurring after retinal pigment epithelium (RPE) and choroid graft translocation surgery (RPE-choroid TS).

Methods: Retrospective analysis of 36 eyes of 36 consecutive patients who underwent RPE-choroid TS. Longer term follow-up of graft survival focusing on the occurrence of MNV was performed using multimodal imaging.

OCT angiography documented reperfusion of translocated autologous full thickness RPE-choroid graft for complicated neovascular age-related macular degeneration.

PurposeThe purpose of this study is to investigate the reperfusion of translocated retinal pigment epithelium (RPE)-choroid graft in the treatment of patients with neovascular age-related macular degeneration (nAMD), using OCT angiography (OCTA), a novel non-invasive, high-resolution imaging modality.Patients and methodsEighteen eyes of 18 consecutive patients suffering from complicated nAMD underwent RPE-choroid patch graft translocation surgery using a peripheral retinotomy and flap-over technique. We analyzed functional and anatomical outcome using visual acuity, Spectral Domain OCT and OCTA.

Living polymerization via anionic initiation for the synthesis of well-defined PPV materials.

The anionic polymerization of PPV via the sulfinyl precursor route is further investigated. When LHMDS is employed as the base to form the actively propagating quinodimethane system and THF as the solvent, anionic polymerizations can be observed. With the use of tert- butyl-substituted anionic initiators, specific functional groups can be built in the polymer chain and the chain length can be efficiently controlled, which is demonstrated here for the first time.

Retinitis pigmentosa in association with acromegaly: a case report.

Retinal abnormalities, unrelated to visual pathway compression, in acromegalic patients were originally described by Small in 1972 (Smail JM. Primary pigmentary degeneration of the retina and acromegaly in a case of pituitary adenoma. Br J Ophthalmol 1972; 56: 25-31).

Comparison of the effect of Healon vs. Viscoat on endothelial cell count after phacoemulsification and posterior chamber lens implantation.

To evaluate the protective effect of 1% sodium hyaluronate (Healon) vs. a mixture of 4% chondroitin sulfate and 3% sodium hyaluronate (Viscoat) on the central corneal endothelium during surgery, we prospectively examined 20 eyes of 20 patients who underwent clear corneal phacoemulsification and implantation of an intracapsular posterior chamber intraocular lens (PC-IOL) with either Healon (10 eyes) or a combined use of Viscoat and Healon (10 eyes) as viscoelastic material. We compared the central endothelial cell counts, recorded by specular microscopy, preoperatively and 6 weeks postoperatively.
