Başak Bostancı, Yonca Aydın Akova
We present a case of infectious crystalline keratopathy in a patient with Graft-versus-Host disease (GVHD) who developed satellite fungal keratitis. A 51-year-old man was referred for bilateral total persistent corneal epithelial defects with severe dry eye. Although persistent epithelial defect healed with medical therapy, he developed stromal keratitis with satellite lesions confirmed to be secondary to Candida albicans. After three months of antifungal treatment and debridement, improvement of the infiltrates was obtained...

PURPOSE: To report 2 cases with late postoperative Candida albicans interface keratitis and endophthalmitis after Descemet stripping automated endothelial keratoplasty (DSAEK) with corneal grafts originating from a single donor with a history of presumed pulmonary candidiasis. METHODS: Two patients underwent uncomplicated DSAEK by 2 corneal surgeons at different surgery centers but with tissue from the same donor and were referred to the Bascom Palmer Eye Institute with multifocal infiltrates at the graft-host cornea interface 6 to 8 weeks later, and anterior chamber cultures that were positive for the same genetic strain of C...

Purpose: To report the outcomes of implantation of the Boston Type I keratoprosthesis in three patients with Acanthamoeba keratitis (AK), a severe infection that can lead to significant visual loss. Observations: Case series reporting three patients with difficult cases of AK that needed multiple corneal transplantations and glaucoma surgeries. All patients were implanted with the Boston Type I keratoprosthesis device. The main outcomes measure were the visual function and anatomical retention after implantation of the Boston Type I keratoprosthesis...

PURPOSE: To quantify all minor/major adverse events in a large cohort of consecutive corneal transplants, particularly in respect to penetrating keratoplasty (PKP). METHODS: All corneal transplants in the Auckland region over a 10-year period (2000-2009) were identified through the New Zealand National Eye Bank. Relevant clinical records were assessed for this period and 2 years after. All intraoperative or postoperative adverse events/complications, visual acuity, and graft outcomes were recorded...

PURPOSE: To investigate the influence of histocompatibility Y (H-Y) antigen matching on corneal graft survival in primary penetrating keratoplasty (PK). METHODS: Medical records of patients who underwent primary PK at Seoul National University Bundang Hospital between June 2005 and October 2015 were retrospectively analyzed. The eyes were classified into 2 groups: H-Y-compatible (115 eyes) and H-Y-incompatible (23 eyes). The H-Y-compatible group included donor/recipient combinations of male/male (57 eyes), female/male (44 eyes), and female/female (14 eyes)...

A 50-year-old patient presented with dull aching pain with some discomfort in his right eye for the past 2 weeks. History revealed the patient had a past episode of infective keratitis managed medically in a local hospital. The last follow-up record suggested a diagnosis of healed keratitis with corneoiridic scar. On examination, the patient had visual acuity of hand movement and a corneoiridic scar of 7×7 mm with an inferotemporal translucent cystic area measuring 3×4 mm in size with underlying uveal tissue visible...

We report a case of a 24-year-old male patient with post-laser assisted in situ keratomileusis (LASIK) culture-proven mycotic keratitis who developed pupillary block glaucoma on day 19 of medical management. The case was initially managed with multiple Nd-Yag peripheral iridotomy along with systemic and topical antiglaucoma medications. However, an emergency therapeutic penetrating keratoplasty (TPK) with lens extraction was done in view of persistently raised intraocular pressure (IOP) and seclusio pupillae...

PURPOSE: To report for the first time a case of interface Scopulariopsis gracilis fungal keratitis following Descemet's stripping automated endothelial keratoplasty (DSAEK) with a contaminated graft. METHODS: A 57-year-old man with bilateral keratoconus and previous bilateral penetrating keratoplasties (PK) developed graft failure in association with marked corneal ectasia. He underwent a successful DSAEK. Unfortunately, a contaminated graft was transplanted and the following morning we were contacted by the eye bank to inform us a slow-growing fungus had been detected in the culture plates inoculated with dextran solution used to store the issued corneoscleral button...

#13
Raffaele Nuzzi, Francesca Monteu
After penetrating keratoplasty (PK), high astigmatism is often induced, being frequently about 4-6 dpt. According to the entity and typology of astigmatism, different methods of correction can be used. Selective suture removal, relaxing incisions, wedge resections, compression sutures, photorefractive keratectomy, and laser-assisted in situ keratomileusis can reduce corneal astigmatism and ametropia, but meanwhile they can cause a reduction in the corneal integrity and cause an over- or undercorrection. In case of moderate-to-high regular astigmatisms, the authors propose a toric multifocal intraocular lens (IOL) implantation to preserve the corneal integrity (especially in PK after herpetic corneal leukoma keratitis)...

This study aims to develop a cross-linked decellularized porcine corneal graft (cDPC) as a substitute for lamellar donor corneas and to evaluate the feasibility of using cDPC to treat fungal keratitis. The cDPC was prepared by decellularization, chemical crosslinking and γ-ray irradiation. Transparency, effectiveness of decellularization and biomechanical strength of cDPC were evaluated. The safety and efficacy of using cDPC to treat fungal keratitis were evaluated in the rabbit model. The transparency of cDPC was similar to that of a native porcine cornea (NPC), and no intact cells were observed in cDPC except for an insignificant amount of residual shrinking cellular nucleus...

PURPOSE: To describe a modified allogenic simple limbal epithelial transplant (SLET) technique with large donor tissue explants followed by keratoplasty. METHODS: A 69-year-old with conjunctival melanoma on her left eye developed total limbal stem cell deficiency (LSCD) after multiple cycles of topical mitomycin. She also had herpes stromal keratitis while on treatment with mitomycin. She underwent modified allogenic SLET with large donor limbal tissue explants glued on the cornea directly and the amniotic membrane placed over the limbal explants...

Background The great shortage of donor material in Ukraine makes it necessary to find additional sources of transplant material. A possible suitable material are the porcine corneas, as they are similar in structure and biomechanical parameters to the human cornea. The purpose of our study was to analyze the results of therapeutic keratoplasty (KP) with keratoxenotransplants from cryolyophilized porcine corneas in patients with severe necrotizing keratitis. Methods A retrospective analysis of 32 xenotransplantations patients with severe necrotizing keratitis (17 lamellar, 6 stepped perforating, 4 perforating, 5 "biological coverage" according to Puchkovskaya) was completed...

INTRODUCTION: We describe a case of refractory Pasteurella Canis keratitis that initially failed antimicrobial treatment but was successfully treated with a conjunctival flap followed by a penetrating keratoplasty. CASE DISCUSSION: A 70-year-old male had persistent corneal edema related to previous herpes zoster keratouveitis with visual acuity of 20/400. An endothelial keratoplasty was performed with improvement in vision to 20/25. Several months after this surgery the patient developed a corneal infiltrate and cultures grew Pasturella canis...
