PURPOSE To describe a bilateral, central, oval corneal opacity not resembling any known corneal degeneration or dystrophy. METHODS Ophthalmic examination, corneal topography, and pachymetry. RESULTS A 30-year-old woman presented complaining of blurred vision. Biomicroscopic examination revealed bilateral, centrally located, oval, diffuse opacification of the anterior corneal stroma. Corneal...

We aimed to describe congenital keratoglobus with blue sclera in two siblings with overlapping Marshall/Stickler phenotype. Two sisters (ages four and six) with bilateral high astigmatism were evaluated by slit-lamp microscopy. Corneal topography and pachymetry maps were also obtained. Slit-lamp examination revealed that both corneas were globular in shape with peripheral corneal thinning. Pach...

Objectives. To provide a metric to differentiate between hyperopic and myopic ablation of prior LASIK treatment based on the corneal pachymetry profile after laser vision correction (LVC). Methods. Pachymetry data were retrospectively recovered from patients who had previous for refractive purposes 2019 2020. Patients with any disorder excluded. Ablation spherical equivalent was predicted centr...

Purpose To analyze the results of three-year outcomes of combined epithelium-on cross-linking with femtosecond laser ICRS (cross-linking PLUS) for keratoconus management. Design A retrospective multicenter clinical study. Methods 43 eyes of 38 patients were subjected to preoperative and postoperative UCVA, BCVA, refraction, Pentacam pachymetry, and keratometry examinations at 3-, 6-, 12-, 2...

PURPOSE To compare 2 different techniques for predissection of human anterior and posterior lamellar corneal grafts for eye bank storage. METHODS A mechanical microkeratome (group 1, N = 5) and a femtosecond laser (group 2, N = 5) were used to dissect intended 350-microm-deep lamellar planes in deepithelialized donor corneas mounted on an artificial anterior chamber. These corneas were replac...

UVB radiation from sunlight induces an acute corneal inflammation, photokeratitis, accompanied by changes in corneal hydration. We employed a method of ultrasonic pachymetry for daily examination of central corneal thickness as an index of corneal hydration of the rabbit cornea repeatedly irradiated by UVB radiation (312 nm, daily dose of 0.25 J/cm(2) during three or four days) as influenced by...

Objective This study compared the rates of aqueous-humor flow and trabecular outflow in eyes that had undergone YAG laser iridotomy (LI) for primary-acute-angleclosure (PAC) attack and primary-angle-closure suspect (PACS). Methods Patients who had PAC attack in one eye and narrow occludable angles (PACS) in the other eye that had undergone YAG LI were recruited. All underwent complete ophthalmo...
