The reason for the endoresection is the location of the tumor in the vicinity of the macula. Brachytherapy as only means would likely damage the fovea. Endoresection is always combined with brachytherapy, but after removal of the tumor a much lower dose is needed to “sterilize” the sclera. The vitrectomy after 180 degree retinotomy is performed under air to prevent seeding of tumor cells. Also eventual hemorrhage does not compromise the view. The disadvantage of vitrectomy under air is more reflections, especially in pseudophakic eyes.

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.

Vitreo-retinal adhesion is typically extremely tight in high myopia at the posterior pole. Remnants or plaques of hyaloid are often associated with retinal tears, then in conjunction with posterior pole rhegmatogenous retinal detachments. To ignore residual hyaloid would mean to accept a risk of PVR retinal re-detachment. The hyaloid is virtually impossible to discern without the help of triamcinolone. Then it is so adherent that suction is insufficient force to detach it. It requires a forceps maneuver to lift the hyaloid of the retina.

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 microplasmin in the future will facilitate posterior vitreous separation in vitrectomy of children.

Primary vitrectomy has largely replaced bucking procedures because the procedure requires less experience, is more controlled and the retina is attached at the end of the intervention. The steps are as follows. Three port vitrectomy access, core vitrectomy, liquid perfluorocarbon, vitreous base shaving, eventually removal of the flap of the horseshoe tear, PFCL and BSS exchange against air to release subretinal fluid through the retinal hole, laser-or kryo-retinopexy around the hole and eventually 360 retinotomy, air-SF6 or C3F8 exchange.

Since the introduction of dyes in macular hole surgery we recognize the admixture of more or less epiretinal membrane in conjunction with macular hole formation. I do not imply a correlation of epimacular membranes to macular hole formation since even severe pucker formation occur without macular hole. Adressing those combined macular holes and epiretinal membranes we first need to peel the epiretinal membrane, which we find in the non-stained area. Thereafter we need to check whether the ILM went with the epiretinal membrane or whether remnants of ILM are still present and are to be removed more easily in the second part of the peeling.

Usually posterior vitreous aspiration can be achieved by moving the cutter close to the attached retina and maximal suction near the disc or over the temporal vascular arcade. Successful PVD can be recognized by the migrating borderline between attached and detached hyaloid, moving from the posterior pole to the periphery in synchrony with the tip of the cutter.

This is an encapsulated older intraocular foreign body. At the time of injury there was very little vitreous hemorrhage. It was then possible to put a laser barrage around the foreign body to be able to remove the foreign body later on and lower risk of inducing a retinal detachment. Once the capsule is opened by the vitreous cutter the endomagnet attracts the iron foreign body and allows to remove it from the eye via the sclerotomy. Then the hyaloid is detached and removed as well.
