Delayed Bacterial Endotheliitis and Endophthalmitis 11 Years after Cataract Surgery.

Infective endophthalmitis is an uncommon complication following intraocular surgery. Chronic endophthalmitis may present some time after intraocular surgery, making the diagnosis challenging. is a well-recognised causative agent of these chronic infections.

Patient-Reported Outcomes in Keratoconus: A Save Sight Keratoconus Registry Study.

Purpose: The aim of this study was to evaluate the quality-of-life (QoL) status in keratoconus severity subgroups using the Keratoconus Outcomes Research Questionnaire (KORQ) and to determine the relationship between the QoL scores and the standard clinical variables.

Methods: A cross-sectional study was conducted using prospective, web-based Save Sight Keratoconus Registry data. Rasch analysis was conducted on the KORQ data using the Andrich Rating Scale Model.

Psychometric Properties of the Keratoconus Outcomes Research Questionnaire: A Save Sight Keratoconus Registry Study.

Purpose: The aim of this study was to evaluate the psychometric properties of the Keratoconus Outcomes Research Questionnaire (KORQ) in patients enrolled in the Save Sight Keratoconus Registry.

Methods: A cross-sectional study was conducted utilizing prospectively collected web-based registry data. The psychometric properties of the KORQ were assessed using both classical test theory and Rasch analysis.

Bilateral Blebs Secondary to Spontaneous Scleral Perforations.

Purpose: To report an unusual case of bilateral spontaneous scleral perforations.

Methods: A 34-year-old woman presented with bilateral conjunctival blebs and decreased vision in both eyes. There was no history of ocular trauma or surgery and no previous ophthalmic or systemic conditions that may have contributed to the scleral perforations.

Blood flow in intracranial aneurysms treated with Pipeline embolization devices: computational simulation and verification with Doppler ultrasonography on phantom models.

Purpose: The aim of this study was to validate a computational fluid dynamics (CFD) simulation of flow-diverter treatment through Doppler ultrasonography measurements in patient-specific models of intracranial bifurcation and side-wall aneurysms.

Methods: Computational and physical models of patient-specific bifurcation and sidewall aneurysms were constructed from computed tomography angiography with use of stereolithography, a three-dimensional printing technology. Flow dynamics parameters before and after flow-diverter treatment were measured with pulse-wave and color Doppler ultrasonography, and then compared with CFD simulations.

Long-term outcomes of deep anterior lamellar keratoplasty versus penetrating keratoplasty in Australian keratoconus patients.

Purpose: The aim of this study is to compare long-term visual and surgical outcomes after performing deep anterior lamellar keratoplasty (DALK) and penetrating keratoplasty (PK) for keratoconus.

Methods: This is a retrospective review of 73 consecutive patients with keratoconus, managed with DALK or PK, between 2000 and 2010, by a single surgeon. Data were collected on baseline parameters, best-corrected visual acuity (BCVA) in logarithm of the mean angle of resolution (logMAR), subjective refraction, graft survival, and complications.

Design of anthropomorphic flow phantoms based on rapid prototyping of compliant vessel geometries.

Anatomically realistic flow phantoms are essential experimental tools for vascular ultrasound. Here we describe how these flow phantoms can be efficiently developed via a rapid prototyping (RP) framework that involves direct fabrication of compliant vessel geometries. In this framework, anthropomorphic vessel models were drafted in computer-aided design software, and they were fabricated using stereolithography (one type of RP).

Direct surgical repair of corneal perforation in pellucid marginal degeneration: a case series.

Purpose: To report a novel technique for repairing corneal perforations in 5 eyes of 3 patients with pellucid marginal degeneration (PMD). Four cases were successfully repaired with corneal sutures and 1 case required a penetrating keratoplasty.

Methods: Retrospective case series of corneal perforation repairs in the setting of PMD.

Topical Cyclosporin A in the treatment of acute graft rejection: a randomized controlled trial.

Background: Corneal graft rejection is the commonest cause of graft failure. Currently, intensive topical steroid is the treatment for graft rejection.We hypothesized that the use of topical Cyclosporin A (CsA) 0.
