RPE and Choroid Translocation in Geographic Atrophy

Bernd Kirchhof
A major goal in surgery of geographic atrophy is the atraumatic creation of a submacular space by subretinal injection of BSS. Often the retinal-RPE-Choroid-adhesion is to tight, that water is insufficient. Then a spatula manoevre is advised with the tip of the spatula pointing to the RPE and choroid. Damage of Bruchs membrane is attempted to later on allow ingrowth of connecting vessels from the original choroid to the transplant. The surgical steps are as...

Removal of heavy silicone oil from the posterior surface of the natural lens

Bernd Kirchhof
Apparently not only silicone but rarely also the natural lens provides a surface for strong adherence of silicone oil, in this case heavy silicone oil (Densiron®). The removal is possible by a solvent for silicone oil: F6H8 or F4H5, two semifluorinated fluorocarbons. The solvent plus the fluid jet manage to remove the oil form the surface of the natural lens.

Transconjunctival 25 gauge vitrectomy

Gabor B. Scharioth
Transconjunctival 25 gauge pars plana vitrectomy has evolved considerably since its introduction. New stiff instruments and technical progress expanded the scope and indications and reduced the limitations. This video shows the author’s experience in 25 gauge vitrectomy used for several indications. Primarily this technique was used for simple vitrectomy, epiretinal membrane peeling and macular hole surgery. Recent improvements in the instrumentation and illumination enable the surgeon to perform sutureless transconjunctival 25 gauge vitrectomy for the...

Posterior Vitreous Separation by Tano Scraper

Bernd Kirchhof
There are few instances when either triamcinolone or fluid jet are insufficient to help detach the hyaloid. This is my only indication in vitreo-retinal surgery to use a Tano scraper. Its rough and sticky “tongue” entangles with the collagen fibres of the hyaloid and can provide the starting edge for the cutter.

Removal of silicone oil from a silicone intraocular lens

Bernd Kirchhof
Although F6H8, a semifluorinated fluorocarbon, is a solvent for silicone oil, the solvent is not powerful enough to dissolve the oil and clean the lens simply by contact. It requires the force of a fluid jet to detach the oil form the surface of the silicone lens. This is the first time, that silicone oil can be removed from silicone intraocular lenses, avoiding the lens exchange. However a complete removal of remnants of silicone oil...

Transretinal resection of submacular hemorrhage

Alireza Mirshahi
Several methods have been introduced for the treatment of submacular hemorrhages secondary to age-related macular degeneration. Small bleedings may be dislocated by intravitreal injection of SF6 gas, possibly combined with recombinant tissue plasminogen activator (rTPA). Larger hemorrhages can be treated by pars plana vitrectomy, subretinal injection of rTPA and gas tamponade. Large and particularly thick bleedings may require additional procedures such as subretinal lavage or the surgical removal of blood clots. Moreover, macular translocation surgery...

No ILM present in a case of PVR

Bernd Kirchhof
The intention to peel the ILM over the macula was to prevent Pucker formation later on in a case of PVR. Suprisingly there was not staining for ILM with ICG, and no tissue typical for ILM could be peeled off. Instead the consistency of the tissue was that of glial tissue or nerve fibre layer. Apparently it is possible that ILM is not developed at all.

Missed Posterior Vitreous Separation in a Child with PVR Reaction

Bernd Kirchhof
The surgeon meant to have separated the posterior hyaloid. But especially in children the vitreous separation is likely to be incomplete or non-existent at all despite vitrectomy. Leaving the hyloid in place raises the risk of a PVR reaction. As shown here the fibrous condensations were confined to the hyaloids and no relevant traction was evident on the retina. The indication for vitrectomy was a retinectomy as pressure lowering procedure in refractive glaucoma. I hope...

RPE and Choroid Translocation in Anti-VEGF-Non-Responder

Bernd Kirchhof
Until present it is difficult to indentify an Anti-VEGF Non-Responder early enough for submacular surgery to be still worthwhile. In this case (typically) surgery was considered not before VA had dropped to 0,1. There was an absolute scotoma temporal to the central fixation (microperimetry). Otherwise the surgical technique is identical to the approach for exsudative AMD before the introduction of VEGF-Blockers: Vitrectomy Posterior vitreous separation (if not yet present) 360 degree laser cerclage Laser demarcation...

Surgery of proliferative vitreoretinopathy (PVR): A step by step approach

Manish Nagpal & Vikram Mehta
Proliferative vitreoretinopathy (PVR) often leads to failure in retinal detachment surgery. Surgeons need to be well versed with managing different aspects of retinal detachment complicated by PVR to achieve successful outcomes. Various techniques such as membrane peeling, dissection, air fluid exchange , endo-drainage, endo laser, usage of perfluorocarbon liquid (PFCL), retinectomies etc. are shown in detail. Carefully assessing the PVR and managing it can improve the surgical outcomes in these cases.

RPE and Choroid Translocation in massive submacular hemorrhage

Bernd Kirchhof
Usually when larger blood volumes are being removed from underneath the macula then the RPE goes with the blood. An RPE substitute is then required, either by macular translocation or by translocation of a free transplant of pigment epithelium and choroid. The latter is shown here.
