background: toxoplasma gondii is an obligate, intracellular protozoon that develops its sexual stage in cat’s intestinal epithelial cells as definitive host and develops its asexual stage in different tissues of a wide range hosts called intermediate host. the protozoon is a food-borne and worldwide parasite that can cause serious complications such as abortion in pregnant women, encephalitis, ...

purpose : up to 70% of patients with acquired immunodeficiency syndrome (aids) have aids-related ocular involvements which may severely affect their quality of life caused by visual impairment. this study was designed to investigate the ocular manifestations in patients infected with human immunodeficiency virus (hiv). methods : in this case series study, 41 hiv positive patients were investiga...

purpose : to evaluate the accuracy of ocular sonography in measurement of size of intraocular foreign bodies (iofb) methods : in a case series study, 58 consecutive patients with intraocular foreign body were included. ocular sonography was performed to detect intraocular foreign body and the results were compared with the same intraoperative findings. results : metallic material was found to b...

UNLABELLED Ocular dominance manifests itself in tests that contain stereo-objects with a disparity beyond Panum's area, e.g. in pointing a finger. These tests force subjects to decide in favour of one or the other eye. In contrast, ocular prevalence is determined using stereo-targets imaged within Panum's areas. These tests allow a graded quantification of the balance between the eyes. Here we ...

Ocular Surfaces In article number 2200283, Jinyao Liu, Lu Lu, Yan Pang, and co-workers describe a strategy of forming long-acting protective ocular surface against external viral invasion by instilling adhesive dual-antiviral nanoparticles, which are enabled coating antiviral agent-loaded nanoparticles with “double-lock” hybrid cell membrane.

As lesões de globo aberto são um tipo grave lesão ocular que exigem avaliação e tratamento imediatos para evitar complicações preservar a visão. Essas ocorrem quando há uma ruptura na parede do ocular, expondo o conteúdo intraocular. A prevalência dessas é relativamente baixa, mas elas representam emergência médica significativa.As frequentemente causadas por trauma contuso, perfurante ou penet...

  Aims: Ocular injury by mustard gas (HD) leads to severe eye damage. Long term characterization of mustard gas ocular toxicity has not been described in detail yet. Present study was performed in order to explore chronic histological and immunopathologic effects of HD ocular exposure and try to find etiology for these effects.   Methods: This descriptive case study was performed on corneal and...

purpose: to evaluate the effect of aamniotic mmembrane ttransplantation (amt) in the management of acute severe ocular chemical burns. methods: this randomized clinical trial was performed in eligible patients with grade iii & iv acute chemical burn who randomly received conventional medical therapy (15 eyes) versus combined medical & amniotic membrane transplantation (15 eyes). main outcome me...
