A 30-year-old patient went to the emergency department because of a chemical burn to the left eye more than 10 days ago by toilet cleanser. Surprisingly, a small piece of glass was found in the inferior anterior chamber in the same eye. The visual acuity was counting fingers. There was conjunctival congestion, corneal oedema and Descemet's membrane striae. And there was also a corneal leukoma around 4 to 5 o'clock. Through repeated questioning he recalled that he was injured by an exploded light bulb around 21 years ago...

PurposeSeverely subluxated crystalline lenses pose a difficult situation to anterior segment surgeons and can only be managed surgically by removal of the lens as well as the capsular bag. Several techniques have been described in literature for the management of such cases. We describe a modified technique of endocapsular lens aspiration by the limbal route for lens extraction through small incisions on the cornea.Patients and methodsThirty-two eyes of 16 consecutive patients with severely subluxated crystalline lenses were recruited in the study...

Mihori Kita, Yukiko Fujii, Sachiyo Hama
Drying of the cornea during surgery, which causes poor visibility of the fundus, is one of the most serious problems when using a noncontact-type wide-angle viewing system. This study used a newly commercialized lens for observing the fundus with a noncontact wide-angle viewing system. The lens used has a very thin meniscus made of polymethyl methacrylate and a large outer diameter. Following the application of viscoelastic material, the lens can be put on the cornea without using a contact lens fixation ring...

PURPOSE: The management of chronic ocular hypotony and complicated proliferative vitreoretinopathy-related retinal detachment represents a challenge. Being non-absorbable and non-biodegradable, a silicone oil implant is expected to restore the volume and the intraocular pressure of the globe, as well as to approximate the detached retina. Further advantages could be a long-term tamponade potential, absence of toxicity, and prevention of silicone oil emulsification or anterior chamber oil-prolapse...

BACKGROUND: A traumatic wound dehiscence can occur many years after surgery in 2-6% of all keratoplasties. Intraocular tissue prolapse can lead to severe visual loss. Deep anterior lamellar keratoplasty (DALK) leads to higher wound stability because of the intact Descemet membrane. We report a case of a novel management of wound dehiscence following DALK. METHODS: A 59-year-old patient underwent uncomplicated DALK for advanced keratoconus. Eighteen months later he experienced a traumatic wound dehiscence (globe rupture) after a fall...

INTRODUCTION: Corneal burn grade IV usually leads to blindness. Several different surgical techniques remain challenging owing to the extensive tissue damage. Here, we introduce a novel technique with a 15 mm corneoscleral and limbal homologous graft combined with sequential autologous corneal removal ab interno, with a vitrectomy probe to save the anterior chamber angle. In vivo anatomy with optical coherence tomography is the surgical key. METHOD: A large 15 mm sclerocorneal graft is sutured on top of the remainder of the destroyed cornea and sclera after removal of the epithelium and conjunctiva, with anterior synechiolysis if necessary, peripheral iridectomy and conjunctivoplasty...

This is a prospective clinical assay that included six patients who were diagnosed with penetrating corneal injury, traumatic cataract, and posterior segment intraocular foreign body (IOFB). Following anterior segment repair and extraction of traumatic cataract by clear cornea phacoemulsification, a standard 25-gauge transconjunctival pars plana vitrectomy was performed to find and release the IOFB. With active suction using a 25-gauge silicone tipped cannula, the foreign body was retrieved and safely placed in the anterior chamber...

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.

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...

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...

COMPARATIVE STUDY
Zhong Lin, Rong Han Wu, Ye Hui Zhou
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...
