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...

dorzolamide ophthalmic drop is one of the most common glaucoma medications but it has a short residence time in the eye. the aim of this study is to develop ocular dorzolamide hcl nanoliposomes (drz – nanoliposomes) and to evaluate their potential use for the treatment of ocular hypertension. nanoliposomes were prepared using reverse-phase evaporation vesicle (rev) and thin layer hydration (tlh...

purpose: to determine the prevalence of intraocular injuries in patients with blow-out fracture and also to evaluate the etiologic mechanism of orbital blow-out fractures methods: this study is a consecutive case series analysis of 116 patients with orbital blow-out fractures. the patients were visited by an ophthalmologist within 24 hours of trauma. results: ninety-one men and twenty-five wome...

we are describing a new surgical approach in the management of advanced ocular surface cicatrization through a single procedure conjunctival-limbal-corneal allograft in which the external eye is resurfaced it involves a lamellar corneolimbal keratoplasty, 360° limbal stem cell transfer (on a “bipedicle” conjunctival-corneal carrier), and conjunctival tissue transplantation - all in a single con...

BACKGROUND The purpose of this study was to investigate the correlation between ocular perfusion pressure and ocular pulse amplitude in glaucoma, ocular hypertension, and normal eyes. METHODS Ninety eyes from 90 patients were included. Thirty patients had been recently diagnosed with glaucoma and had no previous history of treatment for ocular hypotension, 30 had elevated intraocular pressure...

Background: During the COVID-19 pandemic, the presence of ocular symptoms was common in COVID-19 patients, which can cause secondary complications in the treatment of ocular diseases. On the other hand, obesity can cause secondary symptoms in infectious diseases by impairing the function of the immune system, which indicates the relationship between involvement of different tissues and dysfunct...

results this cross-sectional study included 92 patients (47 male and 45 female) with mean age of 32.1 ± 13.16 years (ranging from nine to 61 years of age). mean duration of vitiligo was 10.84 ± 10.17 years. the most common distribution of the lesions was on the upper limbs (60.8%) and the least was on the genital region (10.8%). positive family history was found in 26 (28.3%) patients. diabetes...
