Topographic corneal changes in children with moderate to severe blepharokeratoconjunctivitis.
J AAPOS
January 2025
Department of Ophthalmology, University of California San Francisco, San Francisco, California. Electronic address:
Purpose To determine the corneal topographic characteristics of children with blepharokeratoconjunctivitis (BKC), a chronic inflammatory ocular surface disease involving the lid margin, conjunctiva, and cornea. Methods The corneal topography of 21 children diagnosed with BKC between March 2008 and June 2019 at a single institution were reviewed retrospectively. Pachymetry and asymmetry indices were also analyzed.

The study aimed to compare the effects of different types of excimer laser keratectomy on rabbit corneas and to identify the optimal disease model for corneal ectasia. Additionally, investigating the structural and molecular alterations in the novel disease model helped explore the mechanisms underlying biomechanical cues in corneal ectasia. 2.

Eye Unit, Department of Medical and Surgical Specialties, Radiological Sciences, and Public Health, University of Brescia, 25123 Brescia, Italy.
: The aim of this study was to evaluate the effect of a surgical technique for managing post-penetrating keratoplasty (PK) ectasia complicated by late endothelial failure (LEF). : A single-center pilot case series was conducted regarding consecutive patients affected by post-PK ectasia with late graft failure. Using a microkeratome, a single donor cornea was dissected to prepare a two-piece graft, comprising a larger anterior lamella made up of anterior stroma and a smaller posterior lamella made up of posterior stroma, Descemet's membrane, and endothelium.

Objective: To determine if scleral fittings that occur before corneal cross-linking (CXL) are still successful after the procedure.
Methods: This prospective study included seven patients with keratoconus or post-laser-assisted in situ keratomileusis (LASIK) corneal ectasia who were fitted with scleral lenses then underwent CXL. Four patients (six eyes) had keratoconus and three patients (five eyes) had post-LASIK ectasia.
Unilateral Corneal Ectasia After Bilateral Transepithelial Photorefractive Keratectomy.

December 2024
Department of Ophthalmology, The University of Jordan, Amman, JOR.
We present the case of a 23-year-old male who experienced vision loss in his left eye 15 months after undergoing bilateral transepithelial photorefractive keratectomy (T-PRK). Despite the absence of any significant preoperative topographical risk factors in either eye, corneal ectasia was later confirmed in the left eye, while the right eye remained normal. Subtle asymmetry in topometric indices and a borderline high Index of vertical asymmetry (IVA) reading suggested the possibility of early subclinical keratoconus, potentially increasing the risk of post-refractive ectasia.
