Neurotrophic keratitis after micropulse transscleral diode laser cyclophotocoagulation. [PDF]

open access: yes, 2019
PurposeTo report two cases of neurotrophic keratitis (NK) after micropulse transscleral cyclophotocoagulation (MP-TCP).ObservationsTwo patients with predisposing factors for decreased corneal sensation developed NK 1 month after MP-TCP. Both patients did

Persistence of Innate Immune Pathways in Late Stage Human Bacterial and Fungal Keratitis: Results from a Comparative Transcriptome Analysis [PDF]

open access: yes, 2017
Microbial keratitis (MK) is a major cause of blindness worldwide. Despite adequate antimicrobial treatment, tissue damage can ensue. We compared the human corneal transcriptional profile in late stage MK to normal corneal tissue to identify pathways ...

Learning to Segment Corneal Tissue Interfaces in OCT Images [PDF]

open access: yesarXiv, 2018
Accurate and repeatable delineation of corneal tissue interfaces is necessary for surgical planning during anterior segment interventions, such as Keratoplasty. Designing an approach to identify interfaces, which generalizes to datasets acquired from different Optical Coherence Tomographic (OCT) scanners, is paramount.

In vivo imaging of human cornea with high-speed and high-resolution Fourier-domain full-field optical coherence tomography [PDF]

open access: yesarXiv, 2020
Corneal evaluation in ophthalmology necessitates cellular-resolution and fast imaging techniques allowing accurate diagnoses. Currently, the fastest volumetric imaging technique is Fourier-domain full-field optical coherence tomography (FD-FF-OCT) that uses a fast camera and a rapidly tunable laser source.

Bessel Function Model for Corneal Topography [PDF]

open access: yesApplied Mathematics and Computation 223 (2013), 436-443, 2011
In this paper we consider a new nonlinear mathematical model for corneal topography formulated as two-point boudary value problem. We derive it from first physical principles and provide some mathematical analysis. The existence and uniqeness theorems are proved as well as various estimates on exact solution.

Deep Sequential Feature Learning in Clinical Image Classification of Infectious Keratitis [PDF]

open access: yesarXiv, 2020
Infectious keratitis is the most common entities of corneal diseases, in which pathogen grows in the cornea leading to inflammation and destruction of the corneal tissues. Infectious keratitis is a medical emergency, for which a rapid and accurate diagnosis is needed for speedy initiation of prompt and precise treatment to halt the disease progress and

On fractional Bessel equation and the description of corneal topography [PDF]

open access: yesarXiv, 2012
In this note we apply a modified fractional Bessel differential equation to the problem of describing corneal topography. We find the solution in terms of the power series. This solution has an interesting behavior at infinity which is a generalization of the classical results for modified Bessel function of order 0.
