vitrectomy cornea

Manisha Agarwal, Manisha C Acharya, Shahana Majumdar, Lagan Paul
Ophthalmia nodosa with vitreoretinal involvement is rare and may cause permanent loss of eye due to persistent inflammation of the eye. A young female patient having multiple caterpillar hair in the eye including cornea, anterior chamber, sclera, and pars plana presented with recurrent vitritis and pars planitis. Ultrasound biomicroscopy played a vital role and helped in localizing the hair embedded in the pars plana region which were managed by pars plana vitrectomy leading to complete recovery.

PURPOSE: To evaluate the corneal topographic changes and postvitrectomy astigmatism after 27-gauge (g) microincision vitrectomy surgery (MIVS) by using Pentacam HR-Scheimpflug imaging system. METHODS: This prospective descriptive study included 30 eyes of 30 patients who underwent 27-g MIVS. All eyes underwent a Pentacam HR examination preoperatively and on the first week, first month and third month postoperatively. The power of the corneal astigmatism, mean keratometry (K m), K 1 and K 2 values and corneal asphericity (Q value) values for the both front and back surfaces of the cornea, index of surface variance (ISV), index of vertical asymmetry (IVA), index of height asymmetry (IHA), index of height decentration (IHD) and higher-order aberrations including coma, trefoil, spherical aberration, higher-order root-mean-square and total RMS were recorded...

To present a combination technique for two cases of in-the-bag intraocular lens (IOL) luxation into the vitreous cavity. Vitrectomy was performed via a cornea microincision vitrectomy system, and the luxated IOL was fixed into the sclera. IOL fixation is simple from no trocar cannulas and less disrupted conjunctiva. Postoperative corneal endothelial cell density in Case 1 and Case 2 were reduced by -2.1% and -5.1%, respectively. Postoperative frequency of hexagon was decreased in Case 1 but maintained in Case 2...

BACKGROUND: Endogenous bacterial endophthalmitis is a rare but potentially devastating intraocular infection that can have severe sight-threatening complications. Most patients with endogenous bacterial endophthalmitis have underlying infectious conditions, such as diabetes or malignancy, which predispose them to infection. CASE REPORT: A 1-year-old girl presented with cloudiness of the right eye. Ocular examination showed a cloudy cornea in the right eye with conjunctival injection and hypopyon...

Intraocular foreign bodies (IOFBs) may be associated with occult exit wounds. The authors present a case of a man who sustained a zipper-tooth IOFB through the cornea from a car tire explosion. CT showed an IOFB within the vitreous cavity, but the IOFB was not identified during vitrectomy. Extension of the peritomy revealed an exit wound with the foreign body lodged in the extraocular space. This case demonstrates that IOFBs can rest within the vitreous cavity after creating an exit wound, but may escape detection by being driven back out of the globe during vitrectomy due to the pressurized eye...

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...

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...

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...
