Background: The study aimed to evaluate and compare the leukocyte chemotactic activities of various brimonidine tartrate (BT) eye drop formulations.
Methods: A 96-well dot-blot platet using a Boyden-style well was used to study the chemotactic effects of BT ophthalmic preparations. A modification was made to create blind wells where the tested agents were placed.
Purpose: The aim of study was to evaluate the cross-link using riboflavin and ultraviolet A (UVA) for improving scleral wound healing.
Materials And Methods: This was an experimental study involving four New Zealand rabbits (eight eyes). Therapy procedure was chosen for the right eye and control procedure for the left one.
Purpose: To compare anisometropic hypermetropic amblyopic and strabismic amblyopic responses to pattern electroretinogram (PERG) and pattern visual evocated potential (PVEP).
Materials And Methods: Fifty-six patients - 18 hypermetropic anisometropic amblyopic children (mean age 9.70±2.
Objective: To identify the causes of low visual acuity and systemic morbidities that limit ambulation and access to eye care in geriatric clinics in Rio de Janeiro.
Methods: This cross-sectional study evaluated 187 patients from three geriatric clinics in Rio de Janeiro between January 2010 and January 2011. The inclusion criteria were individuals with a visual acuity of less than of equal to 20/200 in either eye (118 individuals), without optical correction.
Background: To examine the immunohistochemical expression of heat shock protein 90 (Hsp90) and Ki-67 protein in human pterygium.
Materials And Methods: Tissues obtained during pterygium surgery of 15 patients who underwent the bare-sclera procedure and 10 normal conjunctivae were studied. All of these pterygia were primary ones.
Purpose: To evaluate central corneal thickness (CCT) and ocular biomechanical properties in patients before and after clear corneal phacoemulsification.
Methods: Corneal hysteresis (CH), corneal resistance factor (CRF), corneal-compensated intraocular pressure (IOPcc), and Goldmann-correlated IOP (IOPg) were measured with the Ocular Response Analyzer (ORA; Reichert Ophthalmic Instruments) in 36 consecutive patients (47 eyes) who underwent clear corneal phacoemulsification. Central corneal thickness was measured with the Pentacam (Oculus Optikgeräte GmbH).
Familial amyloidosis of the Finnish type (FAF) is an autosomal dominant form of systemic amyloidosis showing marked geographic clustering in Finland. The disease is caused by a point mutation, 654G-A, in the gelsolin gene. The Danish-subtype of FAF has been previously described in three families, the patients present clinical findings similar to FAF, and the mutation 654G-T in the gelsolin gene.

Methods: The participants consisted of 48 patients (96 eyes) with asymmetric POAG. Three measurements of IOP and OPA were taken using DCT.
Background: The aim of this study was to evaluate the efficacy of a one-stage treatment for the blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) using a combination of standard surgical techniques.
Methods: This is a retrospective interventional case series study of 21 BPES patients with a 1-year minimum follow-up period. The one-stage intervention combined three different surgical procedures in the following order: Z-epicanthoplasty for the epicanthus, transnasal wiring of the medial canthal ligaments for the telecanthus, and a bilateral fascia lata sling for ptosis correction.
Purpose: To analyze the possible predisposing factors of lawsuits involving ophthalmologists.
Methods: Retrospective study of 70 lawsuits involving the practice of Ophthalmology. The patient's gender, age, medical and ophthalmic history were reviewed.
Purpose: To compare the performance of gonioscopy and noncontact morphometry with anterior chamber tomography (High Resolution Pentacam - HR) using optical Scheimpflug images in the evaluation of the anterior chamber angle (ACA).
Methods: Transversal study. 112 eyes from 74 subjects evaluated at the Glaucoma Department, Fluminense Federal University, underwent gonioscopy and Pentacam HR.
Cystoid macular edema is an uncommon, but well known, side effect of latanoprost. Two cases of bilateral and simultaneous cystoid macular edema associated with latanoprost use are described, which complete resolution of the edema is observed upon drug discontinuation.

The patient presented with a history of unilateral painless red eye and displayed on examination a nodule in the superior orbital rim, proptosis, and neurotrophic keratitis. Clinical and radiographic examinations were followed by biopsy of the orbital mass.
View Article and Find Full Text PDFPurpose: To report the visual prognosis and longterm complications in patients with multifocal choroiditis and panuveitis (MCP).
Methods: A retrospective study was performed with patients who met inclusion criteria for MCP at the Uveitis Clinic, Royal Victoria Hospital, McGill University, Montreal, Canada. Information collected included duration of follow-up, visual acuity (VA) measured at each clinical visit, ocular and systemic treatment and ocular complications observed during follow-up.
