In-Office Sulfur Hexafluoride (SF6) Injection to Close Recently Operated or Reopened Macular Holes: A Minimal Approach Technique.

To describe an in-office minimal approach technique for closing recently operated full thickness macular holes (FTMH), when closure was not fully achieved or there was macular hole re-formation, without performing another pars plana vitrectomy (PPV). Retrospective case series study. Nine patients were included in this case series.

Learning curve of sutureless transconjunctival 20-gauge vitrectomy.

Background: To report the learning curve of transition from 20-gauge (20 G) conventional vitrectomy to a 20 G sutureless vitrectomy technique.

Materials And Methods: This is a retrospective descriptive case study of 32 eyes from 32 consecutive patients who underwent sutureless 20 G pars plana vitrectomy. A 20 G microvitreoretinal blade was introduced, beveled transconjunctivally, slowly, parallel with the limbus, creating a conjunctivoscleral tunnel incision.

Surgical treatment of retinal detachment associated with degenerative retinoschisis.

Purpose: Although degenerative retinoschisis is almost always asymptomatic, retinal detachment occurs in some patients with outer layer breaks (OLBs). The purpose of this study is to evaluate the different surgical techniques used for the treatment of this condition.

Methods: Retrospective interventional case series.

Perfluorocarbon liquids in vitreoretinal surgery: a review of applications and toxicity.

Since their introduction by Chang et al. in 1987, perfluorocarbon liquids (PFCLs) have become a useful tool in vitreoretinal surgery. They are synthetic compounds with carbon-fluorine chemical chains that have specific physico-chemical properties, which make them valuable for the intraoperative management of the retina by simplifying vitreoretinal surgical maneuvers in a variety of settings.

Does sulfur-hexafluoride tamponade, as an adjunct to vitrectomy and internal-limiting-membrane peeling, suffice for the treatment of retinal detachment associated with macular hole?

Objective: To evaluate the efficacy of sulfur hexafluoride tamponade, as an adjunct to vitrectomy and internal-limiting-membrane peeling, for the treatment of retinal detachment (RD) associated with macular hole (MH).

Materials And Methods: Our study was a retrospective interventional case series. We evaluated 9 phakic eyes of 9 consecutive patients with retinal detachment secondary to macular hole (MHRD) treated with 20-gauge (g) pars plana vitrectomy, which was followed with trypan blue-assisted internal-limiting-membrane peeling, fluid-air exchange, and 20% sulfur hexafluoride tamponade (SF(6)) gas exchange.

Presumed endophthalmitis following Boston keratoprosthesis treated with 25 gauge vitrectomy: a report of three cases.

Background: Although endophthalmitis is known to occur frequently in patients with KPros, the management remains a challenge both due to the lack of evidence and the exceptionality of the examination and the therapeutic approach.

Materials And Methods: Three patients implanted with Boston keratoprosthesis for management of ocular cicatricial pemphigoid and severe alkali injury presented with severe late-onset (10-24 months post-operatively), presumed bacterial endophthalmitis. Three-port 25-gauge (g) pars plana vitrectomy was performed in all patients; vitreous samples were acquired and intravitreal vancomycin and cefuroxime were administered.

Optic disc pit maculopathy treated with vitrectomy, internal limiting membrane peeling, and gas tamponade: a report of two cases.

Purpose: Two cases with optic disc pit associated maculopathy, treated with vitrectomy surgery with internal limiting membrane peeling (ILM) and gas tamponade, are presented.

Methods: Interventional case reports.

Results: Two patients with serous macular detachment associated with a congenital optic pit underwent vitrectomy surgery, induction of posterior vitreous detachment, peeling of the ILM, and gas tamponade.

Sutureless Transconjunctival 20 Gauge pars plana Vitrectomy.

Purpose: Sutureless Transconjunctival 20 Gauge Vitrectomy (20G STV) is a technique that reduces the operating time and the post-operative inflammation.

Patients And Method: Eighty-four eyes underwent this new technique. Conjunctival diathermy over the ports before sclerostomy produced adhesions adequate to stop transoperative conjunctival chemosis.

Perifoveal traction retinal detachment following successful optic disc pit surgery.

A 25-year-old male presented 8 years after a successful vitreoretinal operation for a left optic disc pit (ODP). On presentation his visual acuity had reduced from 6/5 (20/15) to 6/12 (20/40) in his operated eye. On examination an annular serous retinal detachment possibly secondary to tangential traction by either the internal limiting membrane (ILM) or residual lamellar vitreous cortex or both around the peripheral macular area was seen.

Lamina puncture: pars plana optic disc surgery for central retinal vein occlusion.

Objective: To determine the feasibility of creating a perivascular space adjacent to the central retinal vein at the level of the lamina cribrosa as a potential method of reestablishing perfusion in central retinal vein occlusion.

Methods: Various designs for a puncture instrument, or lamina puncture lancet, were investigated in cadavers, pigs that had undergone enucleation, and in vivo rabbit eyes.

Results: A lancet with a sharp cutting edge on one side and an opposing blunt edge is repeatedly able to create a perivascular space with limited optic nerve fiber damage.
