Sengul Ozdek, Prabu Baskaran, Levent Karabas, Pedro Pereira Neves
The authors describe a modified perfluoro-n-octane (PFO)-assisted autologous internal limiting membrane (ILM) transplantation technique for macular hole (MH) reintervention and present results from a series of 11 patients. The authors harvested a free ILM flap and transplanted it into the MH under a PFO bubble. The time at which PFO is injected, the extent of coverage of PFO, and the sequence of fluid-air exchange (FAE) are crucial to overcome previously described technical difficulties of relieving the flap from forceps, stabilizing the flap into the MH, and prevention of flap dislodgement during FAE...

C Seppey, T J Wolfensberger
Background Myopic foveoschisis is a rare form of a tractional maculopathy, which occurs in patients with elevated axial length. The contraction of the posterior hyaloid exerts tangential traction on the retinal surface with a subsequent continuous splitting of the retinal layers. Internal limiting membrane (ILM) peeling has been advocated in foveoschisis, but it has been associated with post-operative macular hole formation. We report on a modified surgical technique, which spares the fovea and may reduce the risk for macular hole formation...

BACKGROUND: Silicone oil (SO) is used as an intravitreal tamponade agent in vitreoretinal surgery for rhegmatogenous retinal detachment (RRD) complicated by proliferative vitreoretinopathy or with large, multiple retinal tears. Usually, SO is left in the eye for at least 3 months. Although its use can lead to well-known complications, intraocular SO is generally well tolerated. Some studies have reported unexpected central vision loss after SO use or removal. OBJECTIVE: To investigate and analyze the reason for visual loss after the use or removal of intraocular SO in patients who underwent vitrectomy surgeries for RRD...

Ocular cysticercosis is a serious condition with a potential for complete vision loss if left untreated. Intravitreal cysticercosis is the most common ocular form of cysticercosis and is associated with retinal detachment, retinal traction, subretinal scarring and vitritis. To the best of our knowledge, there is no report of the occurrence of a live intravitreal cysticercosis with a full thickness macular hole (FTMH) in the literature. We here report a case of live intravitreal cysticercosis with a FTMH along with its management and intraoperative optical coherence tomography features of the live cysticercus...

Zahra Ghomi, Fariba Ghassemi
Despite being a posterior segment ocular surgery, pars plana vitrectomy (PPV) may also affect anterior segment parameters. We aimed to investigate anterior segment alterations following PPV using ultrasound biomicroscopy (UBM) to visualize the structural anatomy of the eye. In this study, we enrolled phakic patients undergoing PPV (as the sole procedure). The anterior chamber depth, crystalline lens anterior-posterior (AP) diameter, anterior chamber angle, ciliary body dimensions, and integrity of the ciliary zonules and posterior capsule were assessed using UBM before and at least 3 months after PPV...

A 75-year-old Caucasian female with a full-thickness macular hole underwent a successful surgical repair. Vision improved from 20/400 to 20/30 after surgery. Two years later, the patient presented with a decreased vision after a fall onto her face with a reopened full-thickness macular hole. Vision decreased to 20/400 and then she underwent a second surgery with an internal limiting membrane peeling, which resulted in a second successful closure of her macular hole. Vision following the second surgery was 20/100...
