Polyhexamethylene Biguanide Multipurpose Solutions on Bacterial Disinfection: A Comparison Study of Effectiveness in a Developing Country.

Objective: The aim of this study was to compare the antimicrobial action of commercially available multipurpose disinfection solutions (MPDS) with and without hydrogel contact lens for disinfection of isolated corneal bacteria.

Methods: Five commercially available MPDS in Brazil (BioSoak, Clear Lens, OPTI-FREE, Renu, and UltraSept) were tested against Pseudomonas aeruginosa , Staphylococcus aureus , and Staphylococcus epidermidis . All five MPDS were also tested on P.

Corneal Perforation associated with "Silent Brain Syndrome".

This case report describes the clinical characteristics and ophthalmic management of a patient who developed corneal perforation due to severe enophthalmos consistent with "silent brain syndrome." A 27-year-old man with a history of congenital hydrocephalus and ventriculoperitoneal shunt was referred with complaints of "sinking of the eyeballs" and progressively decreasing vision in the left eye. Examination revealed severe bilateral enophthalmos in addition to superonasal corneal perforation with iris prolapse in the left eye.

Ocular manifestations in classic homocystinuria.

Background: Classic homocystinuria (HCU), or cystathionine beta-synthase (CBS) deficiency, is a rare inborn error of methionine metabolism. Main clinical features may include skeletal and vascular manifestations, developmental delay, intellectual disability and eye disorders.

Material And Methods: This is an observational and retrospective study aiming at describing eye abnormalities presented by a cohort of late-diagnosed HCU patients.

Individual Macular Layer Evaluation with Spectral Domain Optical Coherence Tomography in Normal and Glaucomatous Eyes.

Purpose: To evaluate differences in the thickness of the individual macular layers between early, moderate, and severe glaucomatous eyes and compare them with healthy controls.

Patients And Methods: Subjects with glaucoma presenting typical optic nerve head findings, high intraocular pressure with or without visual field (VF) damage and normal controls were included. All participants underwent 24-2 perimetry and spectral-domain OCT.

A three-dimensional printed photopolymer resin implant for orbital rehabilitation for evisceration.

Purpose: To evaluate the biocompatibility of three-dimensional (3D) printed orbital spheres for evisceration.

Materials: A total of 10 consecutive patients (eight females and two males; mean age, 46.8 ± 14.

Whole-exome sequencing in familial keratoconus: the challenges of a genetically complex disorder.

Purpose: The underlying genetic causes of keratoconus are essentially unknown. Here, we conducted whole-exome sequencing in 2 Brazilian families with keratoconus.

Methods: Whole-exome sequencing was performed on 6 keratoconus-affected individuals of 2 unrelated pedigrees from Southern Brazil.

Use of a Neural Net to Model the Impact of Optical Coherence Tomography Abnormalities on Vision in Age-related Macular Degeneration.

Purpose: To develop a neural network for the estimation of visual acuity from optical coherence tomography (OCT) images of patients with neovascular age-related macular degeneration (AMD) and to demonstrate its use to model the impact of specific controlled OCT changes on vision.

Design: Artificial intelligence (neural network) study.

Methods: We assessed 1400 OCT scans of patients with neovascular AMD.

Factors associated with cesarean sections in a high complexity university hospital in southern Brazil.

Objective To identify the factors associated with cesarean sections in a high complexity university hospital in southern Brazil. Methods Cross-sectional study carried out at the Obstetric Hospital Unit of the Hospital de Clínicas de Porto Alegre. Data were gathered from questionnaires carried out with 361 puerperal women and maternal and neonatal records, from February to April 2013.

Update and review of Urrets-Zavalia syndrome.

For more than half a century, Urrets-Zavalia syndrome (fixed dilated pupil) has been described as a postoperative complication of ophthalmic surgery. Since first reported as a complication of penetrating keratoplasty for keratoconus in patients receiving atropine, the characteristic features of Urrets-Zavalia syndrome have been expanded. In previous literature, a total of 110 cases resulted in a fixed and dilated pupil.

Update in the Management of Macular Edema Following Retinal Vein Occlusions.

Retinal vein occlusion (RVO) is a common retinal vascular disease classified according to the anatomical location of the occlusion in central (CRVO) or branch (BRVO) retinal vein occlusion. RVO is an important cause of visual loss worldwide and frequently results in visual impairment and ocular complications. Major causes of vision loss in BRVO and CRVO include macular edema (ME), capillary non-perfusion, and neovascularization, causing glaucoma, vitreous hemorrhage and/or tractional retinal detachment.

Phialemonium curvatum infection after phacoemulsification: a case report.

Purpose: A case of Phialemonium curvatum wound corneal infection after phacoemulsification is reported.

Methods: Case report.

Results: The marked aggressiveness of this fungus is demonstrated by the absence of therapeutic response to both medical and surgical treatment.

[Use of bevacizumab (Avastin) in KID syndrome: case report].

KID syndrome is a congenital ectodermal dysplasia characterized by the association of keratitis, hyperkeratotic skin lesions and neurosensorial hearing loss. Ocular involvement occurs in 95% of patients. Although KID syndrome cutaneous manifestations have been studied in-depth, the treatment and prognosis of ophthalmic impairment have not been described in detail.

[Bilateral acute angle closure glaucoma in a young patient receiving oral topiramate: case report].

This paper reports a clinical case of uveal effusion in both eyes causing bilateral acute angle closure glaucoma in a young patient after oral administration of topiramate, a new anticonvulsant medication. Rarely, some drugs have produced uveal effusions, forward shift of the iris-lens diaphragm, transient myopia and secondary angle closure glaucoma. A 40-year old white woman was seen at the emergency department of the "Hospital Banco de Olhos de Porto Alegre (RS)"--Brazil, with severe headaches and blurry vision in both eyes.

[Comparative study of the biometric measurements made by immersion and contact techniques].

Purpose: To compare clinical biometric findings between measurements of immersion technique and contact technique.

Methods: Axial length was measured by A-scan in 120 medical examinations in 60 patients with cataract using a non-contact (immersion) and a contact technique in paired-samples by ultrasound.

Results: The mean axial length was found to be 23.

Use of oral voriconazole as adjunctive treatment of severe cornea fungal infection: case report.

A case of Aspergillus flavus keratitis was successfully treated with oral voriconazole and penetrating keratoplasty after conventional antifungal medical therapy failure.
