PURPOSE: To evaluate the influence of the body weight and body mass index (BMI) on the intraocular pressure (IOP) peaks and fluctuation in the water-drinking test (WDT) in primary open angle (POAG) and normal tension glaucoma (NTG) patients, as well as normal eyes (NE). METHODS: Thirty-two eyes of 32 POAG patients, 30 eyes of 30 NTG patients and 20 eyes of 20 normal patients were evaluated in this transversal study. None of the patients were using antiglaucomatous drugs at the […]

We decribed a case of endothelitis that began with keratoneuritis in patient who wore soft contact lens and saline solution with poor hygiene. A 41 years old ,white female suffered from severe pain in her left eye, with microcystic corneal edema and radial keratoneuritis .Culture and corneal byopsia was made, and all tests were negative.The treatment including topical dexametasona 0.1% ophthalmic solution and oral acyclovir successfully controlled the corneal edema and the pain.

The authors prepare a literature review about the main antioxidants used in daily practice for the prevention of age-related macular degeneration progression (AMD), emphasizing the mechanism of action of each substance as well as the possible complications related to the overuse of such components.

OBJECTIVE: Evaluate the visual response of children with developmental dyslexia when ambiguous figure was presented in comparison with normal readers children. METHODS: 39 children from basic school was randomly chosen. 26 were normal readers. 13 were diagnosed developmental dyslexia.Were presented the Boring figure, Rubin vessels figure and Jastrow figure. RESULTS: Participants in the clinical group with dyslexia performed marginally less well than those in the control group. CONCLUSION: The visual response of children with developmental dyslexia when ambiguous figure was […]

PURPOSE: There are several methods to measure the Interpupilary Distance (IPD), but the method used in most office is the milimetric ruler. Currently, the autorrefractor is used routinely to find for the subjective evaluation of the refractive error, but the IPD from the autorrefractor is often not compared with the traditional method of measurement.The objective of the study is to achieve the measures of IPD between the two methods and compare the results with each other. METHODS: One hundred and […]

PURPOSE: This is to study the progressive addition lens (PAL) under the physiological optics’ view, to show the lensometer findings and its applicability to daily work. METHODS: At first, the aa., explains the ways to examine the PAL , and then indicates the physical basis applied to study the prismatic system of the concave and convex lens. It then examines the differences on progression zone extension and explains its diagonal position. Thirteen pairs of lenses from the same manufacturer were […]

PURPOSE: To evaluate the outcome and safety of the transition from phacoemulsification performed by third year residents using peribulbar anesthesia to topical anesthesia. METHODS: Cases performed by third year residents from august 2004 to february 2005 were analyzed. Patients were operated under peribulbar (group I) and topical anesthesia (group II). Variables analyzed included patients age, sex, visual acuity under pinhole and complications. Patients with low visual acuity other than cataract were excluded from analysis. RESULTS: A total of 151 eyes […]
