PurposeTo determine whether the inverted internal limiting membrane (ILM) flap technique contributes to high reattachment and closure rates in patients with macular hole-associated retinal detachment (MHRD).Patients and methodsIn all, 15 eyes of 15 patients with MHRD undergoing 25-gauge pars plana vitrectomy with the inverted ILM flap technique or ILM peeling. The patients were divided into the inverted ILM flap technique group (6 eyes) and ILM peeling group (9 eyes). The logarithm of minimal angle of resolution best-corrected visual acuity (BCVA) and retinal attachment and macular hole closure rates were compared between the two groups before and after surgery...

This photo essay shows the transient therapeutic effect of pars plana vitrectomy (PPV) in a patient affected by primary intraocular lymphoma (PIOL). PPV is crucial for the diagnosis of PIOL, but it may also play a role in the therapeutic approach.

PURPOSE: To investigate the closure rate of primary full-thickness macular hole, following intraocular air tamponade combined with a nonsupine positioning regimen. METHODS: A prospective study of patients with full-thickness macular hole, who underwent pars plana vitrectomy with internal limiting membrane peeling and intraocular air tamponade followed by 3 days of nonsupine positioning. Outcome measures were primary full-thickness macular hole closure and improvement in best-corrected visual acuity after 6 months...

Purpose: Cytokines play an important role in cell signaling in inflammatory and repair processes, also within the posterior segment of the eye. These molecules are thus implicated in the pathophysiology of several vitreoretinal diseases. In the present study, we compared vitreal cytokine profiles in patients with idiopathic epiretinal membranes (ERMs) and idiopathic full-thickness macular holes (MHs) without epiretinal membranes. Methods: Native vitreal humor was collected during elective pars plana vitrectomy for the treatment of macular pathologies (group 1: ERM; group 2: MH) from patients without any other ocular or systemic disease...

PURPOSE: To evaluate functional and anatomic outcomes of eyes undergoing suprachoroidal buckling (SCB) using a specially designed catheter for the management of rhegmatogenous retinal detachment (RRD) secondary to peripheral retinal breaks. METHODS: Retrospective cohort study of 62 eyes of 62 patients. Subjects underwent SCB for the management of RRD secondary to single or multiple retinal breaks.

PURPOSE: The purpose was to evaluate the results of modified sleeve in phacoemulsification of cataract in completely vitrectomised eyes, Materials and Methods: Twenty-five previously completely vitrectomized eyes of 23 patients having visually significant cataract were included. After through evaluation they underwent phaco-emulsification by phaco chop with a modified sleeve via temporal clear corneal incision. The modified sleeve was made by creating a small round port of approximate 1 × 1 mm size at the proximate end of the sleeve in line with the already existing ports...

Infectious endophthalmitis is an important cause of vision loss worldwide. This entity most often occurs as a complication of intraocular surgery especially following cataract surgery or intravitreal injection. Endophthalmitis is regarded as a serious complication following ocular surgery and the final visual outcome is fundamentally contingent on timely recognition and intervention. Intravitreal and oral antibiotics in combination with pars plana vitrectomy or vitreous aspiration remain the mainstay in the management of endophthalmitis...

BACKGROUND: Presence of subretinal abscess in endogenous endophthalmitis indicates a more severe form of infection. Available reports indicate variable response to standard treatment with systemic, intravitreal pharmacotherapy and vitreous surgery. There are no reports citing the possible role of intralesional antibiotic therapy in managing subretinal abscess.

BACKGROUND: To compare early visual and anatomical outcomes after either sulfur hexafluoride (SF6) or perfluoropropane (C3F8) tamponade for macular hole repair. METHODS: 147 eyes affected by primary full-thickness macular hole underwent pars plana vitrectomy with dye assisted removal of the internal limiting membrane and gas tamponade. Prone position was prescribed for 48 h after surgery. All patients were divided into 3 groups depending on the size of the hole: small (<250 µm), medium (>250-<400 µm) or large (>400 µm)...

To report a case of retinal vasoproliferative tumor (VPT) with secondary epiretinal membrane (ERM) formation and vitreo-macular traction managed by pars plana vitrectomy (PPV) and membrane peel. A 29-year-old male was referred for management of decreased vision in the right eye (OD) for 1 week. Presenting visual acuity was 20/50 Snellen feet (ft) OD, and fundus examination showed an ERM associated with a reddish-yellow mass in the inferotemporal quadrant with overlying exudation, hemorrhage, and subretinal fluid consistent with VPT, and cryotherapy was recommended...

Ophthalmomyiasis interna posterior is a rare condition caused by the invasion of the ocular posterior segment by the larval form of certain flies in the order Diptera. The main clinical features are reduced visual acuity, intense posterior uveitis, and neuroretinitis. Treatment of this condition is predominantly surgical, including argon laser photocoagulation for subretinal larva and pars plana vitrectomy for intravitreal infection. We report a case of ophthalmomyiasis interna posterior in a 12-year-old girl that masqueraded as orbital cellulitis and was successfully treated with Nd:YAG laser photodisruption...
