    An unusual presentation of ocular rosacea.
    Arq Bras Oftalmol 2017 Nov-Dec;80(6):396-398
    Department of Pathology, Marmara University School of Medicine, Istanbul, Turkey.
    Rosacea is a chronic, progressive disease of unknown cause affecting the eye and the facial skin. Ocular rosacea is often underdiagnosed if the ophthalmologist does not inspect the patient's face adequately during the ocular examination. Severe ocular complications and blindness can occur if the treatment is delayed because of non-diagnosis of the rosacea. Read More

    Trocar-assisted intrascleral sutureless fixation of a dislocated three-piece sulcus intraocular lens.

    Topical tacrolimus for the treatment of severe allergic keratoconjunctivitis in children.
    Arq Bras Oftalmol 2017 Jul-Aug;80(4):211-214
