    Posterior argentinean flag-like sign during primary posterior continuous curvilinear capsulorhexis.
    Arq Bras Oftalmol 2017 Jun;80(3):199-201
    Department of Ophthalmology and Visual Sciences, Universidade Federal de São Paulo, São Paulo, SP, Brazil.
    We describe a unique complication during primary posterior continuous curvilinear capsulorhexis (PCCC) in a patient with megalocornea scheduled for phacoemulsification with toric multifocal intraocular lens (IOL) implantation. After nucleus emulsification and cortex removal, the capsular bag was filled with cohesive viscoelastic in preparation for PCCC to achieve reverse optic capture of the IOL, thus ensuring stability. However, as soon as the initial puncture was made using a 27-gauge needle to start the capsulotomy, the posterior capsule opening extended peripherally from 0º-180º. Read More

    Translation and validation of the Portuguese version of a dry eye disease symptom questionnaire.
    Arq Bras Oftalmol 2017 Jan-Feb;80(1):14-16
    Discipline of Ophthalmology and Otorhinolaryngology, Faculty of Medical Sciences, Universidade de Campinas (UNICAMP), Campinas, SP, Brazil.

    Purpose:: To assess the accommodation response after short reading periods using a tablet and a smartphone as well as determine potential differences in the accommodation response at various stimulus vergences using a Hartmann- Shack aberrometer.

    Methods:: Eighteen healthy subjects with astigmatism of less than 1 D, corrected visual acuity of 20/20 or better, and normal findings in an ophthalmic examination were enrolled. Accommodation responses were obtained under three different conditions: accommodation system of the eye relaxed and visually stressed with a tablet and an smartphone for 10 min, at a distance of 0.

    Purpose:: The aim of this study was to evaluate tear osmolarity, tear film function, and ocular surface changes in patients with psoriasis.

    Methods:: At a single center, 30 eyes of 30 patients with psoriasis (group 1) and 30 eyes of 30 healthy individuals (group 2) were evaluated using the Ocular Surface Disease Index (OSDI) questionnaire, Schirmer I test, tear film break-up time (TBUT) test, scoring of ocular surface fluorescein staining using a modified Oxford scale, and tear osmolarity measurement.

    Results:: Tear osmolarity values, OSDI, and Oxford scale scores were significantly higher in group 1 (309. Read More
