Effectiveness of monthly and fortnightly anti-VEGF treatments for age-related macular degeneration

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT Purpose: To study the efficacy and safety of treatments with ranibizumab and bevacizumab for exudative age-related macular degeneration. Methods: A parallel randomized clinical trial was conducted to compare the efficacy and safety of three regimens (bevacizumab every month, bevacizumab every ...

Optical biometry-based axial length alterations after intravitreal dexamethasone implant

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT Purpose: To investigate changes in axial length after intravitreal dexamethasone implantation in patients with macular edema. Methods: We performed a prospective comparative study of 46 patients with unilateral macular edema, due to diabetic retinopathy, retinal vein occlusion, and non-infecti...

Intravitreal and posterior subtenon triamcinolone acetonide for severe acute posterior multifocal placoid pigment epitheliopathy

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT A 21-year-old man presented with visual acuity of 20/200 in both eyes. The fundus picture, fluorescein angiography, and optical coherence tomography revealed severe bilateral acute posterior multifocal placoid pigment epitheliopathy and serous macular detachments. We treated the patient with tri...

Multisectorial changes in the ciliary muscle during accommodation measured with high-resolution optical coherence tomography

Arq. bras. oftalmol; 82 (3), 2019
ABSTRACT Purpose: To measure changes in the anterior ciliary muscle during accommodation at the nasal, superior, temporal, and inferior sectors by means of an anterior chamber optical coherence tomographer, and correlate them with vergence changes. Methods: Twenty-four subjects with healthy, phakic eye...

Foveosquisis miópica asociada al Síndrome de Straatsma
Myopic foveoschisis associated with Straatsma's syndrome

Rev. cuba. oftalmol; 32 (2), 2019
RESUMEN Este reporte describe la presentación concomitante de foveosquisis miópica y fibras de mielina en una paciente con miopía elevada. La primera puede ser un hallazgo incidental, pero no infrecuente en pacientes con miopía elevada, y causa pérdida visual central severa. La segunda es infrecuent...

Rev. méd. Chile; 147 (4), 2019
Background: Balloon pulmonary angioplasty (BPA) is a therapeutic alternative for patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH). Aim: To report the initial experience with the "refined BPA technique" with the use of intravascular images. Patients and Methods: Between Jun...

Retinal dystrophies and variants in PRPH2

Arq. bras. oftalmol; 82 (2), 2019
ABSTRACT - This report presents three patients diagnosed with macular dystrophies with variants in PRPH2. Peripherin-2, the protein of this gene, is important in the morphogenesis and stabilization of the photoreceptor outer segment. Peripherin-2 deficiencies cause cellular apoptosis. Moreover, pathogeni...

Effect of contact lenses on ocular biometric measurements based on swept-source optical coherence tomography

Arq. bras. oftalmol; 82 (2), 2019
ABSTRACT Purpose: To determine the reliability of swept- source optical coherence tomography in cases in which soft contact lenses cannot be removed when acquiring biometric measurements. Methods: Eight subjects were included and only one eye per participant was analyzed. Each eye was measured six time...
