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...

Corneal surprise during vitreoretinal surgery

Francisco J. Ascaso, Paula Casas & Enrique Mínguez
A 65-year old man underwent pars plana vitrectomy for dislocated lens fragments into the vitreous cavity during a previous cataract surgery. The right eye anterior chamber exam showed three nylon 10/0 corneal sutures and fundus examination revealed dislocated lens fragments into the vitreous cavity. There was no history of refractive surgery. The patient was scheduled for a standard 20-gauge three-port pars plana vitrectomy. During the surgery a big epithelial bleb appeared in the corneal surface...

Exchange of multifocal IOL decentered in a fibrose capsular bag in the lens-IOL

Marie-José Tassignon
A case of an IOL exchange. It is a multifocal slightly tilted IOL. The patient was operated six years ago. When she was in the mean time operated on the other eye with a bag-in-the-lens toric correction, she saw the difference and wanted to have an exchange of this decentered lens. The quality of vision was otherwise not good enough for her dominant eye.

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...

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...

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...

23 gauge vitrectomy and subretinal rTPA injection for submacular hemorrhage

Joachim Puchta & Alireza Mirshahi
This video shows 23 gauge sutureless pars plana vitrectomy, subretinal injection of recombinant tissue plasminogen activator (rTPA) and SF6 endotamponade for treatment of a submacular hemorrhage secondary to age-related macular degeneration. The subretinal injection is performed using a 41 gauge cannula. The preferred injection area is the temporal margin of the hemorrhage. Postoperatively, face-down position is necessary for dislocation of the blood. Subsequent treatment of the choroidal neovascular membrane is necessary for disease control, e....

The bell pepper experiment: introducing a novel self-sealing “screwcut” incision for sutureless transconjunctival vitrectomy

L.-O. Hattenbach
Flattened sclerotomies are an essential step in ensuring postoperative wound stability in transconjunctival sutureless vitrectomy. However, in complex cases involving complete vitrectomy with shaving of the vitreous base, laser application and peeling of surface membranes, conventional angled incisions often leak at the end of the procedure. Here, we present a novel curved and twisted (screw-like=“screwcut“) self-sealing incision technique using a 23-gauge one-step microcannula array with sharp solid trocar blades. Based on a simple kitchen experiment,...

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...

“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...

Cataract surgery with penetrating keratoplasty after anterior lamellar dissection

Non
We introduce a new technique that after anterior stromal dissection, cataract surgery is performed with clear vision, and then, the posterior stroma isremoved and penetrating keratoplasty is completed for an eye that had penetrating keratoplasty and cataract surgery planned. Partial thickness corneal incision was done with a Hessburg-Barron trephine. From the corneal incision, anterior stroma dissection was performed with an angled crescent blade. When the dissection was over, the anterior stroma was excised with a...

Transplantation of a free RPE-choroid graft in patients with exudative AMD

Jan Van Meurs
82 year old female, 5 Avastin injections for a vascularized RPE detachment, submacular hemorrhage treated with vitrectomy/TPA/gas in the acute stage, revealing an RPE-tear with VA of 20/800. RPE transplantation in an effort to reconstitute the underlayer of the macula.
