PVR Surgery through a Boston Keratoprothesis

Bernd Kirchhof
PVR retinal detachment followed the implantation of a Boston keratoprothesis. The video shows PVR-vitrectomy viewing the back of the eye through the keratoprothesis. The central retina can be seen without problem. The peripheral retina cannot be seen ideally, even with indentation. The alterative is to pull the peripheral retina centrally for retinotomy with the help of a forceps. Basically all necessary steps in PVR surgery can be fullfilled through a Boston keratoprothesis.

Liège -7000 ans, les derniers chasseurs préhistoriques de Wallonie : Archéologie du Mésolithique et Expérimentation ; Rapports d'études préliminaires des zones 19 et 20 des fouilles de Tivoli

Eva DAVID & René-Ginouvès Prod. Maison Archéologie Et Ethnologie
Exhumé par le Service Public de Wallonie, un matériel archéologique inédit a été retrouvé à l’archéoforum de Liège (Tivoli). Daté de la transition Mésolithique-Néolithique, il pose la question du mode de vie des derniers chasseurs-cueilleurs à l’arrivée des premiers colons agro-pasteurs, il y a environ 7000 ans. Les premiers résultats de l’étude sont livrés, ainsi que ceux des tests expérimentaux conduits au Préhistosite de Ramioul. Ces derniers ont notamment permis de retrouver des techniques préhistoriques...

Subchoroidal Infusion with Air, Water, Silicone oil

Bernd Kirchhof
The typical situation for subchoroidal infusion is ocular hypotony. In the first instance hypotony exists because an infusion in place is removed and another infusion is introduced through the same sclerotomy. The line contains air which instantly escapes through the adjacent sclerotomy for the light pipe. An angulated spatula is used from the opposite site of the infusion to free the tip of the subchoroidal infusion cannula from ciliary body tissue. Eventual remaining subchoroidal air...

25 gauge vitrectomy techniques for proliferative diabetic retinopathy

Florian Balta
The proliferative diabetic retinopathy (PDR) cases are operated on with 25 G instruments, under the OFFISS System as viewing system, and the Constellation vitrectomy machine at 5000 cuts / minute ,using either an unimanual or a bimanual technique. In the unimanual technique, the vitreous cutter is used. In the bimanual technique, the combination between the intraocular forceps and the vitreous cutter is used. Less frequent the illuminated spatula and the forceps are used together. The...

IOL Luxation during silicone oil removal

Bernd Kirchhof
In an eye with a subluxated IOL and during silicone oil removal, all of a sudden the IOL disappears, possibly because the caspular bag was aspirated with the oil. Soon thereafter the iris is transiently aspirated by the aspiration needle. The IOL is found on the retina of the posterior pole. It is elevated with a flute needle (silicone tipped), grasped with foreps by its haptics and extracted via a sclerotomy. Later on a chamger...

Uveal effusion syndrome: diagnosis and management

S. Chien Wong & Paul M. Sullivan
Uveal effusion syndrome (UES) is a difficult condition to accurately diagnose and treat. In this video, we illustrate the features, differential diagnoses and management of UES using a combination of surgical clips and 3D animation. Surgical treatment with sclerectomy is demonstrated, including tips for effective control of sclerectomy depth. Good anatomical and visual outcomes can be achieved following sclerectomy for UES. Uveal effusion syndrome is a challenging condition to diagnose and treat. Good outcomes can...

Peeling of Epiretinal Membranes in PVR

Bernd Kirchhof
Starfolds in PVR show considerable retinal traction, but the causing epiretinal membrane is rarely clearly to discern from the underlying retinal tissue. One must then grab the navel of the fold and while pulling tangentially learn by the difference in elasticity what is membrane and what is retina. The primary goal is to release traction. An incidental retinal hole is a minor disadvantage over leaving behind epiretinal membranes. However all retinal holes need to be...

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.

Endoresection of Choroidal Melanoma

Bernd Kirchhof
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...

CNV Adherent to Macula

Bernd Kirchhof
Especially in long standing CNV, like occult CNV, fibrotic PED the RPE-Choroid complex is eventually tightly adherent to the outer retina. In this older film an angulated subretinal forceps is being used as a spatula as well in order to sever off the CNV from the outer retina. Apparently here the connation is too strong. Thus during the subsequent pulling a macular hole is created. The strong adhesion is apparent from the indentation (navel) of...

Dancing nematodes in the eye

Avinash Pathengay, William Aylward, Biju Raju, Jalli Gangadhar, Kolli Goverdhan Babu & Shobha Mocherla
Ocular nematode infections such as cysticercosis, diffuse unilateral subacute neuroretinitis (DUSN) and filariasis are commonly seen in the developing nations of the world. In this video, we will highlight the features and management of five cases comprising of cysticercosis (intravitreal, subretinal and inside the anterior chamber), diffuse unilateral subacute neuroretinitis and ocular filariasis. The epidemological features, clinical characteristics and medical and surgical options are highlighted. When alive, an intra-vitreal cysticercus can move and shy away...

Sutureless intraocular lens fixation of a dislocated intraocular lens - capsular bag - capsular tension ring complex

Kannan Naresh Babu & Ramasamy Kim
Intraocular lens (IOL) implantation and fixation techniques are controversial in eyes with insufficient or no capsular support. In such eyes, cataract surgery can be performed using a capsular tension ring and an IOL implanted in the bag. Dislocation of this IOL-capsular bag-capsular tension ring (IOL-CB-CTR) complex is rare, but can happen in cases with zonular dialysis or a history of trauma. We report a technique of removal of the CTR with sutureless fixation of the...

“Oh! I find the way – I can create retinal detachment” - Gnathostomata spinigerum

Subhendu Kumar Boral, Santanu Mandal, Arnab Das & Tushar Kanti Sinha
A 30 years old female presented in Disha Eye Hospitals, Barrackpore, West Bengal, India with panuveitis with progressive tractional retinal detachment (TRD) involving macula in right eye. Her left eye was absolutely normal. An actively motile worm was detected at pars plana area at the time of vitreous base excision and removed in intact motile form. The large granulomatous tissue over the disc with thick epimacular membranes were removed. The retina was reattached and silicone...

Low viscosity silicone oil as infusion fluid in vitreous hemorrhage

Bernd Kirchhof
In vitrectomy of massive vitreous hemorrhage the view is typically compromised by stirred blood. In order to speed up the procedure saline as infusion fluid is replaced by very low viscosity silicone oil. The silicone has the advantage not to mix with blood. At the same time all vitrectomy procedures can be performed as like under saline. The much improved view into the eye should shorten the procedure. In the end the silicone oil as...

Transretinal biopsy technique for cytogenetic phenotyping of posterior uveal melanoma

Javier Elizalde
Cytogenetic phenotyping is a world-wide accepted procedure in ocular oncology to know the risk of metastatic disease of uveal melanoma. We describe our effective and safe vitreoretinal surgical technique to obtain a sample of melanomas located posterior to the equator. A three-port 25-gauge microcannulae system through the pars plana is used to insert a vitrector or a 27-gauge needle to obtain the tissue, depending on the size of the tumor. Although minimal bleeding may be...

Removal of Heavy Silicone Oil

Bernd Kirchhof
Removal of heavy silicone oil takes about 3 minutes, due to its low viscosity of a little more than 1000 cSt. The cannula is a peripheral infusion trimmed to the appropriate length. The tip should reach to about the center of the vitreous cavity, may even less. Smaller bubbles of heavy oil can be aspirated from the posterior pole by a flute needle. Inspection of the retinal periphery with indentation is recommended, because bubbles may...

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...

Membrane on the back Side of the ILM Causing Pucker-like Distortions

Bernd Kirchhof
Even though the ILM stains homogenously the ILM is distorted like in a pucker. The explanation is that the causative membrane resides on the back side of the ILM and bridges to the retina, possibly glial tissue. Thus ILM is a substrate and precondition for membrane formation not matter on which side of the ILM membranes develop.

Full Macular Translocation in Exsudative Age Related Macular Degeneration

Bernd Kirchhof
Core vitrectomy, posterior vitreous separation if not yet present, vitreous base shaving, usually those eye are pseudophakic otherwise the natural lens can be shifted anteriorly by anterior chamber drainage, so that the vitreous base is accessible without damage to the lens. BSS injection is used to detach the retina, first transretinally to create a retinal bleb of sufficient size to allow further BSS injection transretinally via a 30 or 27 gauge cannula. As long as...

Incision making in small gauge surgery

Manish Nagpal
Small gauge surgery or sutureless surgery is gaining widespread popularity. Incision making is the key to the success of achieving a good postoperative wound. Various techniques have evolved related to the incision making and this video discusses the steps of making a good incision. Significance of retracting the conjunctiva using a stabiliser and then placing a biplanar incision are demonstrated. Steps to acheive a good incision closure at the time of removal of cannulas and...

Rupture of the Eye after Bomb Explosion

Bernd Kirchhof
The situation of rupture of both eye balls concerned both eyes after a bomb explosion as a criminal attack. The patient had “perception of light” in both eyes. One eye was primarily enucleated. The other eye was reconstructed as shown here. This is meant as an example of successful reconstruction in an assumingly hopeless situation and as a reason against primary enucleation at the time of emergency surgery. Since there was no ciliary body and...

Scleral loop to fixate an encircling band

Bernd Kirchhof
The standard fixation of an encircling belt is a permanent scleral suture. Sutures have the disadvantage that they eventually may protrude through the conjunctiva, they may cut through the sclera causing dislocation of the belt, or they may be assciated with infections. The scleral loop requires only a round knife (Teller-Messer), formed like a plate. In case of very thin (blue) sclera a suture will not hold and extra sclera need to be sutured onto...
