Objective: To evaluate the clinical features of retrocorneal fungal infection and the therapeutic effects. Methods: This was a retrospective, noncomparative study of nine patients with retrocorneal fungal infection and an intact corneal epithelium treated at Qingdao Eye Hospital. The history, clinical features, diagnostic methods, pathogens and therapeutic effects were analyzed. Results: Five patients had a history of trauma by plant, two had a non-plant injury, and two had unidentified reasons.

BACKGROUND: The Boston Keratoprosthesis (B-KPro) is a therapeutic option for corneal replacement for visual rehabilitation in eyes with poor a prognosis for penetrating keratoplasty (high-risk eyes). Since 2009, this approach has been used in the MVZ Prof. Neuhann, Munich, and since 2013 also at the Department of Ophthalmology, University of Cologne. An overview of results from the first 73 eyes in these departments is presented. METHODS: All recipient eyes of both centers which received a B-KPro type I (BI-KPro) between November 2009 and March 2017 were included...

PURPOSE: To investigate the efficacy and safety of transplantation with biomaterial-free cultured oral mucosal epithelial cell sheets (COMECs) for ocular reconstruction in subjects with total limbal stem cell deficiency. METHODS: A prospective clinical trial (NCT02149732) was conducted in 8 subjects with total limbal stem cell deficiency after approval from the institutional review board of Seoul National University Hospital (H-0707-043-213) and the Ministry of Food and Drug Safety of Korea...

PURPOSE: To determine whether there is an association between socioeconomic status and best-corrected visual acuity (BCVA) in patients undergoing corneal transplantation in the United Kingdom. METHODS: Retrospective cohort study of 4306 patients registered on the national United Kingdom Transplant Registry and undergoing penetrating keratoplasty, anterior lamellar keratoplasty, or endothelial keratoplasty in 2002, 2008, and 2013. Socioeconomic status was determined by applying a validated deprivation index to generate a score based on 5 categories...

A 51-year-old male who had suffered from right eye rhegmatogenous retinal detachment with proliferative vitreoretinopathy received surgical treatments which included the following procedures: lens extraction, scleral buckle, vitrectomy, membrane peeling, photocoagulation, and silicone oil injection. The presenting visual acuity of the right eye was light perception. Slit-lamp examination revealed corneal opacity without a visible fundus. B-scan ultrasonography revealed retinal detachment. Endoscope-assisted vitrectomy was then performed in December 2014...

Compared with conventional penetrating keratoplasty, Descemet's stripping automated endothelial keratoplasty (DSAEK) more effectively maintain global integrity and rapid vision rehabilitation with less ocular surface disorders in patients with endothelial dysfunction. Here, we report a case of a 76-year-old woman who experienced opacification of a hydrophilic intraocular lens (IOL) approximately 10 months after DSAEK. The patient with no history of systemic disease developed pseudophakic bullous keratopathy in the right eye 2 years after undergoing cataract surgery...

PURPOSE: To investigate whether use of donors predisposed by corneal collagen cross-linking (CXL) reduced myopic refractive errors for keratoconic eyes after penetrating keratoplasty (PK). DESIGN: Randomized controlled trial. METHODS: One hundred sixteen eyes of 116 patients with keratoconus from Zhongshan Ophthalmic Center were enrolled. Using stratified block randomization, eligible eyes were assigned to CXL graft group (Group1) or conventional graft group (Group2)...

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...

OBJECTIVES: To report big-bubble deep anterior lamellar keratoplasty (DALK) in patients with keratoconus with corneal stromal scar, and to investigate factors that can influence intraoperative Descemet membrane (DM) perforation. METHODS: A retrospective study included patients with keratoconus with central stromal scar that underwent DALK using the big-bubble technique. Best spectacle-corrected visual acuity (BSCVA), keratometry, minimum corneal thickness (MCT), stromal scar depth, and endothelial cell density (ECD) were recorded...

PURPOSE: In this study, we aimed to provide a new method of corneal preservation by injecting DisCoVisc into the anterior chamber of eyeballs and evaluate its efficiency for corneal transplantation. METHODS: Three pairs of eyeballs (n=6) were preserved by DisCoVisc viscoelastic agent, and the corneas were stored for 1 to 6 days. Then, the structure and morphology of cornea were analyzed by hematoxylin-eosin (H&E) staining, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining, and transmission electron microscopy (TEM)...

INTRODUCTION: It is known that phacoemulsification of cataracts after penetrating keratoplasty there are always some difficulties and of course a higher rate of different intraoperative complications. Phacoemulsification after PK may cause significant endothelial injury and affect long term graft survival. AIM: The aim of this report is to describe one of these cases and the possible ways to manage them. CASE REPORT: We report a case o of a 31-year-old female patient, with a cataract on her left eye...

BACKGROUND: To analyse the associated factors, diagnosis, clinical manifestations and therapeutic effects of Acanthamoeba keratitis at a tertiary ophthalmic centre in Southern China. METHODS: A retrospective clinical study was performed in fifteen patients who were admitted to Zhongshan Ophthalmic Centre (ZOC) from January 2004 to December 2014. The patients' pathogenesis-associated factors were analysed, and preoperative diagnoses were determined using corneal scraping cultures and/or confocal microscopy followed...

We report a case of cataract-combined penetrating keratoplasty that required rekeratoplasty for refractive status because of the inadvertent use of a cornea from a donor who had undergone LASIK surgery. The case presents the use of perioperative visualization, anterior segment optic coherence tomography, and histopathologic confirmation. A 63-year-old female patient with leukoma and cataract in the left eye underwent combined cataract surgery and penetrating keratoplasty. During surgery, a jelly-like layer extending a few millimeters in diameter was observed around the lenticule...

PURPOSE: To compare the long-term results of big-bubble technique and microbubble techniques to complete stroma dissection after failure of achieving a big-bubble. METHODS: A total of 35 eyes with keratoconus underwent lamellar keratoplasty with the big-bubble technique (15 eyes) or the microbubble technique (15 eyes). Conversion to penetrating keratoplasty was performed in 3 eyes of the big-bubble group and in 2 eyes of the microbubble group. Best-corrected visual acuity, corneal thickness, corneal astigmatism, and endothelial cell count were assessed preoperatively and at 12 and 24 months after surgery...

PURPOSE OF REVIEW: In this article, we review the indications and latest management of high-risk penetrating keratoplasty. RECENT FINDINGS: Despite the immune-privilege status of the cornea, immune-mediated graft rejection still remains the leading cause of corneal graft failure. This is particularly a problem in the high-risk graft recipients, namely patients with previous graft failure due to rejection and those with inflamed and vascularized corneal beds. A number of strategies including both local and systemic immunosuppression are currently used to increase the success rate of high-risk corneal grafts...
