摘要:

AbstractCAM treatment was instituted for an 8-week period in a 10-year-old patient who failed to respond well to conventional amblyopia therapy. A small, consistent, statistically significant improvement in visual acuity was found. This improvement was attributed to a change in fixation locus and to practice effects, and not to spatial frequency/ orientation-dependent “reactivation” of cortical neurons involved in the development of amblyopia.

摘要:

AbstractClinical refractive data were obtained on 32 subjects by each of three examiners, each examiner using standard subjective refraction procedures with an endpoint criterion of “maximum plus for best visual acuity.” The results of the three examiners were compared in terms of spherical equivalent refraction, spherical power, cylinder power, cylinder axis, and anisometropia. In addition, results were compared to those of previous studies involving both clinical refraction and the American Optical Corporation's SR III Subjective Refraction System.

摘要:

AbstractSince its approval by the Food and Drug Administration (FDA), timolol has been widely used for the treatment of open-angle glaucoma. Contrary to the clinical trials before FDA approval, many reports of possible ocular and systemic side effects have now appeared. Cardiovascular, respiratory, and gastrointestinal systemic effects occur relatively often and are attributable to β-adrenergic antagonism, but central nervous system (CNS) effects are not so explainable. The most frequent ocular side effects are instillation pain and blurred vision, often requiring discontinuation of timolol. Superficial punctate keratitis and associated reduced corneal sensitivity have been reported and pose a risk for affected contact lens wearers. The incidence of side effects in two prospective studies was about 20%, with some 40% of those having to discontinue timolol. Of optometric interest are reports that timolol increases the electro-oculogram (EOG) ratio (Arden Index), and that it may be used to lower intraocular pressure in acute angle closure when pilocarpine alone is unsuccessful.

摘要:

AbstractVon Graefe phoria measurements were obtained for ten prepres-byopic subjects at 40 cm and 6 m test distances using a vertical column of black letters on red, green, and white backgrounds. Phorias measured at 40 cm using red and white target backgrounds were similar, but the phoria measured using a green target background indicated a change toward greater exophoria. No difference in phoria measurements was found between all targets at 6 m.
