The final these diseases blindness from glaucoma. author developed a hypothesis etiopathogenesis uveopathies, according to which trigger weakness accommodation caused by genetically determined excessively small distance between ciliary body and equator lens. following approaches solving problem are proposed: a). formati...

PURPOSE To comparatively investigate the clinical outcomes, vector parameters, and corneal aberrations of small incision lenticule extraction (SMILE) with a triple centration technique and corneal wavefront-guided transepithelial photorefractive keratectomy (PRK) for the correction of high astigmatism. METHODS This retrospective, comparative case series study included 89 eyes (89 patients) th...

PURPOSE To describe the relation between magnitude of anisometropia and interocular acuity difference (IAD), stereoacuity (SA), and the presence of amblyopia in school-aged members of a Native American tribe with a high prevalence of astigmatism. METHODS Refractive error (cycloplegic autorefraction confirmed by retinoscopy), best corrected monocular visual acuity (VA; Early Treatment Diabetic...

OBJECTIVE The lower recommended age of the donor cornea is a controversial matter. Although newborn corneas have a high endothelial cell density, there are anatomical, refractive (myopic shift) and postoperative problems. Two cases are analyzed; one had an atypical refractive result and the other an unexpectedly severe immune response. We also review the use of pediatric donor corneas in penetr...
