A Parametric Approach to Measuring Limbus Corneae From Digital Images [PDF]

IEEE Transactions on Biomedical Engineering, 2006
It is difficult to demarcate the limbus borders in standard intensity images of the eye since the transition from the cornea (iris) to sclera is gradual.

Automatic estimation of the corneal limbus in videokeratoscopy [PDF]

IEEE Transactions on Biomedical Engineering, 2002
An algorithm for estimating the corneal limbus from videokeratoscopic images is proposed. After the image is transformed to a polar grid, a novel edge-detection procedure, suitable for the detection of the soft edge produced by the limbus, is used to ...

Efficacy of three different methods for side port incision wound sealing

Revista Brasileira de Oftalmologia, 2013
PURPOSE: To evaluate wound leakage and bacteria-sized particle influx in differently corneal sealed side port incisions. METHODS: Four 1.5mm tunnel squared incisions were created in each of four cadaveric human eyes. In each cornea, one incision was left

Evaluation of the Effectiveness of Excision Techniques from Cornea to Limbus and from Limbus to Cornea on Recurrence in Pterygium Surgery

, 2014
Objectives: To evaluate the recurrence rates of two different pterygium excision procedures, i.e. “excision from the cornea to the limbus” and “excision from the limbus to the cornea”.

A Rare De Novo Missense Mutation in IFT122 Confers a Genetic Susceptibility Factor of Idiopathic Pediatric Uveitis Via Trio‐based Whole‐Exome Sequencing

Advanced Science, EarlyView.
A rare de novo IFT122‐A773E variant is identified in idiopathic pediatric uveitis and shown to exacerbate retinal inflammation and barrier dysfunction. Mechanistically, the variant enhances IFT43 interaction, elevates calcium signaling, and activates the MEK/ERK/FRA1 axis, revealing a previously unrecognized cilia‐associated pathway that may increase ...
