BACKGROUND A pterygium is a fibrovascular overgrowth of degenerative conjunctiva over the limbus onto the cornea. The risk factors for pterygium development include exposure to ultraviolet (UV) light, dust, wind, heat, dryness, and smoke. As far as we are aware, rapid growth of pterygium secondary to photorefractive keratectomy (PRK) has not been reported(More)
PURPOSE To compare macular thickness of the normal fellow eye to that of the amblyopic eye using optical coherence tomography (OCT) in children with unilateral high myopia. Relationships between macular thickness and magnitude of myopic anisometropia, axial length, and visual acuity (VA) were investigated. METHODS Thirty-one children with a mean age of(More)
PURPOSE To determine whether different test targets including an accommodative target (AT), a transilluminator (TR), and a transilluminator with a red lens (RL), affect the near point of convergence (NPC) value; and to determine which test target is most sensitive to identify convergence insufficiency (CI) in young adults. METHODS Subjects were 36(More)
PURPOSE Although the treatment of symptomatic convergence insufficiency (CI) with base-in (BI) prism in adults has a strong theoretical foundation, there have been very few studies addressing its efficacy. The purpose of this study was to investigate whether the application of BI prism, using a novel progressive addition lens design which incorporates BI(More)
OBJECTIVES To determine the efficacy of refractive correction alone and patching treatment with near activities on amblyopia associated with myopic anisometropia in children aged 4 to less than 14 years. The associations of visual acuity (VA) improvement with age,degree of anisometropia, patching compliance, presence of strabismus, and presence of eccentric(More)
PURPOSE Test-retest reliability of the CSV-1000 (Vector Vision) has only been reported for one adult sample. We measured the reliability of this instrument in both children and adults and also investigated the effect of changing the examiner on test-retest reliability. METHODS Test-retest log contrast sensitivity (CS) measurements were obtained for 19(More)
PURPOSE The aim was to determine whether baseline measurements of binocular vision are associated with symptoms of convergence insufficiency (CI) both before and after CI treatment with base-in prism in symptomatic presbyopes. We further determined the factors that predicted CI treatment outcomes. METHODS A total of 29 symptomatic CI subjects aged 45 to(More)
PURPOSE To characterize optic nerve head (ONH) parameters including symmetry between the eyes in healthy African American children using the Heidelberg retinal tomograph II, and to determine if there are associations between these parameters and age, refractive error, or gender. METHODS The ONHs of 146 African American children aged 6 to 17 years without(More)
AIM To evaluate corneal astigmatism after phacoemulsification using 2.2 mm or 1.8 mm clear corneal micro-incisions and its effects on visual function. METHODS Sixty cases (60 eyes) with cataract were randomly divided into groups A (n=30) and B (n=30) respectively underwent 2.2 mm and 1.8 mm clear corneal tunnel incision phacoemulsification combined with(More)
