vitrectomy cornea

Yu Ichioka, Akihito Uji, Nagahisa Yoshimura
BACKGROUND: To present an intraoperative acute Descemet's fold formation using swept-source optical coherence tomography (SS-OCT) imaging. CASE REPORT: A 67-year-old man complaining of reduced visual acuity in the left eye. A 25-gauge pars plana vitrectomy combined with phacoemulsification cataract surgery was performed to remove the vitreomacular traction. When hydro-sealing was performed, striae rapidly spread in the cornea. SS-OCT B-scan images performed on postoperative day 1 revealed a wavy Descemet's membrane that might correspond to Descemet's folds...

The purpose of this study was to compare the silicone oil removal rate between vitrectomy and manual syringe negative pressure approach. Thirty-five silicone oil-filled eyes were enrolled and allocated for manual (n = 19) and vitrectomy (n = 16) removal approaches. For manual approach, a 10-ml syringe was connected to the 23-gauge cannula through a short section of blood transfusion tube. Removal was started after pulling and fixing the plunger to the end part. The syringe was pulled away immediately once the residual of silicone oil cannot be observed through the cornea...

BACKGROUND: This study was designed to measure changes in anterior chamber depth (ACD), central cornea thickness (CCT), and axial length (AL) after scleral buckle (SB) surgery or pars plana vitrectomy (PPV) for the repair of rhegmatogenous retinal detachment (RD). METHODS: We prospectively reviewed the records of 245 eyes of 245 patients scheduled to undergo SB surgery and 238 eyes of 238 patients scheduled to undergo PPV. ACD, CCT, and AL were measured by spectral-domain optical coherence tomography (SD-OCT) and biometry, before surgery as well as 6 and 12 months postoperatively...

PURPOSE: To describe the safety and efficacy of removing posteriorly dislocated lens fragments with the use of intravitreal ultrasonic fragmentation through a limbal, clear cornea self-sealing incision. METHODS: Patients presenting with posteriorly luxated nuclei were enrolled in this prospective case series. Preoperative examination included evaluation of the corneal endothelium by means of specular microscopy. A 3-port 25+ pars plana vitrectomy was initially performed...

AIM: To report the fungal organisms, clinical features, surgical treatment strategies, and outcomes of patients with culture-proven exogenous fungal endophthalmitis (EFE) secondary to keratitis, and evaluate the role of surgery in the treatment. METHODS: The clinical records of 27 patients (27 eyes) with culture-proven EFE resulting from fungal keratitis treated at Shandong Eye Institute from January 2007 to January 2015 were retrospectively reviewed. Information about fungal culture results, clinical features, surgical procedures, and final visual acuity was obtained...

AIM: To investigate indications, surgical challenges, and outcome of Descemet-membrane endothelial keratoplasty (DMEK) in patients with retinal comorbidities (RC). METHODS: In a prospective cohort study, 8 eyes of 8 DMEK-patients with known RC were compared to 38 eyes of 38 DMEK-patients without RC. The duration of surgery, the degree of difficulty graded by the surgeon, and the complications through DMEK-surgery were analyzed for each patient. The best-corrected visual acuity (BCVA), the endothelial cell count, the intraocular pressure, and the subjective satisfaction was evaluated after a 6-month follow-up...

To evaluate the occurrence of late-onset corneal haze (LOCH) after vitrectomy for rhegmatogenous retinal detachment (RRD) in photorefractive keratectomy (PRK)-treated eyes. This observational cohort study comprised 13 eyes of 13 patients who underwent vitrectomy for RRD and who had been subjected to PRK years earlier. The occurrence of LOCH was evaluated together with all the preoperative, intraoperative, and postoperative factors that could affect final corneal status. LOCH developed in 2 eyes. Both patients had undergone PRK for high myopia--one 3 years and the other 9 years prior to RRD...

UNLABELLED: Bilateral Fuchs uveitis associated with vitreous infiltration and posterior segment involvement requires a thorough diagnostic evaluation. The lack of well-defined diagnostic criteria makes identification of this entity difficult. The aim of this case report was to present the characteristics of a patient with atypical Fuchs uveitis and the procedures needed to rule out the differential diagnosis with specific attention to the utility of in vivo confocal microscopy (IVCM)...

PURPOSE: To investigate agreement in intraocular pressure (IOP) measurements among Icare rebound tonometry, Tonopen tonometry, and Goldmann applanation tonometry following vitreoretinal surgery. DESIGN: Reliability analysis of tonometers. METHODS: Fifty-eyes of 50 adults undergoing vitreoretinal surgery were enrolled. IOP was measured on first postoperative day using Icare (Tiolat, Helsinki, Finland), followed by Tonopen (Reichert, Depew, New York, USA) and Goldmann (Haag-Streit USA, Mason, Ohio, USA) in randomized order...

Rhinocladiella, a genus of black yeast-like fungi, is related to many infections in humans, including not only mild cutaneous lesions but also fatal brain infections. However, endophthalmitis caused by Rhinocladiella has never been reported by far. Herein, we present the first case of endophthalmitis due to Rhinocladiella basitona. The diagnosis was based on histopathology, mycology, and molecular identification. A 53-year-old female was struck by a piece of wood in her right eye. The wound in the central cornea became an ulcer and was aggravated continuously...

PURPOSE: The purpose of this study is to determine the influence of post-surgical corneal edema on the reliability and reproducibility of central corneal thickness (CCT) measurements by a Scheimpflug camera (Pentacam), ultrasound pachymetry (USP), and anterior-segment spectral-domain optical coherence tomography (AS-OCT). METHODS: Thirty-two patients planned for cataract surgery (n = 16) or vitrectomy (n =  6) were included in a prospective study. The non-surgery eye was used as control...

PURPOSE: To report the results of 9 years of follow-up after caterpillar setae penetration into a child's eye. METHODS: The clinical course of caterpillar setae penetrating an eye and their migration will be described. Initially confined to the anterior segment (conjunctiva, cornea), they later migrated to the anterior chamber and iris toward the posterior pole. Management included treatment of the associated recurrent uveitis and repeated surgical interventions including pars plana vitrectomy...

A 67-year-old man presented with hand motions vision, a decompensated vascularised cornea and a flat anterior chamber in the right eye 5 years following cataract and glaucoma surgery. He lost the left eye several years ago following a similar intervention. The intraocular pressure (IOP) was 19 mm Hg on four antiglaucoma medications and the axial length was 19 mm. In view of the high risk for graft failure, a Boston type 1 keratoprosthesis (Kpro) was planned for visual rehabilitation, and a glaucoma drainage device (GDD) for IOP control...

Recent advances in vitreoretinal surgical technology combined with advances in small-incision cataract surgery have enabled the ophthalmic surgeon to provide combined management of cataract and retinal pathology. Progressive understanding of the inevitability of cataract progression after pars plana vitrectomy along with the negative impact of early cataract progression on visual acuity outcomes have defined the importance of combined cataract surgery and pars plana vitrectomy in improving surgical outcomes...

A wide-angle viewing system offers a panoramic view of the surgical field and also improves the safety and efficacy of the vitreoretinal surgical procedure. Surgeons can easily observe the fundus in almost the whole area and evaluate the retinal pathologies through the panoramic view even in eyes with small pupils, corneal opacity, or eyes implanted with multifocal intraocular lens or toric intraocular lens. Recent wide-angle viewing systems consist of two types: contact lens and non-contact lens. The benefit of the contact lens type is better resolution and contrast of the fundus image compared to the non-contact lens type...

In this case series of 74 patients with coexisting vitreoretinal injury and severe corneal opacification, after temporary keratoprosthesis (TKP) assisted pars plana vitrectomy (PPV), an allograft corneal transplant was not performed at the same time; instead, the patient's trephined corneal button was sutured back. One year after the surgery, if intraocular pressure of the injured eyes was above 8 mmHg, removing silicone oil was attempted, and penetrating keratoplasty could be performed. Finally, 10 eyes (13...
