Metastatic and aggressive renal cell carcinoma mimicking a unilateral choroidal tuberculoma.

Ocular metastases from systemic tumors are uncommon. The choroid is the most frequent target, with a preference for elderly individuals. Lung cancer is the predominant primary tumor that metastasizes to the eyes in males, although other ocular conditions such as uveitis and retinal lesions can mimic secondary tumor implants in ocular tissues.

Bilateral frosted branch angiitis in an initial case of systemic lupus erythematosus.

Frosted branch angiitis is a rare and severe form of retinal vasculitis. It may be idiopathic or arise secondary to a systemic disease. We have reported here an unusually severe case of frosted branch angiitis in a previously healthy 13-year old girl who presented with significantly reduced vision in both eyes.

Sequence of focal choroidal excavation types in a patient with bilateral central serous chorioretinopathy.

A 39-year-old policeman complained of decreased bilateral central vision over the last two years. On examination, visual acuity was 20/40 and 20/400 in the right (OD) and left eye (OS), respectively, and fundoscopy revealed a bilateral hypopigmented macular lesion. Fluorescein and indocyanine green angiography demonstrated leakage and hyperintense spots, respectively, within the macular areas.

Nodular anterior scleritis associated with Berger's disease.

A 45-year-old female patient presented with a complaint of right eye redness and pain for 7 days. She was under investigation for urinary abnormalities and reported a previous history of recurrent oral ulcers and ocular hyperemia in both eyes. Best-corrected visual acuity was 20/30 and 20/20 in the right and left eyes, respectively.

Angioid streaks and optic disc drusen in cherubism: a case report.

A 65-year-old female patient was referred to our hospital for evaluation for cataract surgery. Her past medical history included corrective jaw surgeries for facial deformities that developed during infancy and persisted through early adulthood. A complete ophthalmological examination revealed bilateral angioid streaks, drusen in both optic disc areas, and a subretinal neovascular membrane in the left macula.

Unilateral acute posterior multifocal placoid pigment epitheliopathy in a patient with a strongly positive purified protein derivative test.

A 27-year-old man presented with a complaint of decreased visual acuity in the right eye. Best-corrected visual acuity was 20/60 in the right eye and 20/20 in the left eye. Right eye fundoscopy revealed mild vitritis, multifocal yellowish lesions, and macular serous retinal detachment.

The use of optical coherence tomography for the detection of ocular toxicity by ethambutol.

Objectives: To evaluate, through (OCT), alterations in retinal thickness, secondary to use of ethambutol in the treatment of patients with tuberculosis. In addition to studying the use of simpler semiological tools, such as Amsler and Ishihara, in the screening of these cases.

Methods: Thirty patients with ethambutol were recruited from the reference service of tuberculosis treatment at the Federal University of Espírito Santo from May 2015 to July 2016.

Evaluation of Job-Related Anxiety Symptoms Among Brazilian Social Security Medical Experts.

Objectives: The function of a medical expert within the scope of the Brazilian social security system consists of medically evaluating the examinee to draw a conclusive opinion on the person's working ability capacity and to characterize the disability for social security and assistance purposes. Forensic decisions inevitably converge on two opposite outcomes: concession or refusal. Rejection is against the interests of the candidates, who can direct their disappointment and dissatisfaction at the professional, exposing the latter to potentially stressful situations.

Current Therapy of Acquired Ocular Toxoplasmosis: A Review.

Caused by the parasite Toxoplasma gondii, ocular toxoplasmosis (OT) is the most common form of posterior infectious uveitis. Combined antiparasitic therapy is the standard treatment for OT, but several other schemes have been proposed. The purpose of the present study was to review the literature on the treatment of OT and provide ophthalmologists with up-to-date information to help reduce OT-related visual morbidity.

[Use of intravitreal triamcinolone and laser photocoagulation for the treatment of diffuse diabetic macular edema].

Purpose: To assess the efficacy of intravitreal use of triamcinolone acetonide combined with laser photocoagulation for the treatment of diffuse diabetic macular edema and to compare it with the separate use of each treatment.

Methods: After systemic clinical control, thirty patients with diffuse diabetic macular edema were divided into 3 treatment groups: (1) macular grid photocoagulation; (2) intravitreal injection of 4 mg of triamcinolone acetonide; (3) combination of the two previous therapies. Follow-up was scheduled at predetermined intervals of one day, one week and monthly until completion of six months.

[Morphometric analysis of eyelid fissure in patients with eyelid retraction in acute stage of dysthyroid orbitopathy after treatment with botulinum toxin type A].

Purpose: To compare morphometric data of eyelid fissure using computerized image analysis before and after application of botulinum toxin type A in patients with eyelid retraction caused by dysthyroid orbitopathy in acute stage.

Methods: This was a prospective study with 12 individuals that received transcutaneous 5 UI/0.1 ml injection of botulinum toxin in the upper eyelid.

[Intraoperative adjustable strabismus surgery under drop anesthesia in patients with Graves' orbitopathy].

Purpose: To report the clinical features of strabismus associated with Graves' orbitopathy, and the results of surgery with adjustable suture under drop anesthesia.

Methods: The charts of 13 patients who had surgical treatment for strabismus related to Graves' orbitopathy at Hospital das Clínicas of University of São Paulo were retrospectively reviewed. Ocular motility, sensorial examination and the follow-up after strabismus correction were studied.

Consistency of ocular coherence tomography fast macular thickness mapping in diabetic diffuse macular edema.

Objectives: To investigate optical coherence tomography consistency on foveal thickness, foveal volume, and macular volume measurements in patients with and without diffuse diabetic macular edema.

Introduction: Optical coherence tomography represents an objective technique that provides cross-sectional tomographs of retinal structure in vivo. However, it is expected that poor fixation ability, as seen in diabetic macular edema, could alter its results.

How much information do medical practitioners and endocrinologists have about diabetic retinopathy?

Objective: The objective of this study was to use a questionnaire to evaluate knowledge concerning diabetic retinopathy among the physicians present at the 12th Latin American Congress on Diabetes held in São Paulo, Brazil, September 2004.

Methods: A questionnaire about their experience and management of patients with diabetes mellitus and the ophthalmologic examination was administered to 168 endocrinologists attending the meeting.

Results: Among the 168 physicians, only 36.

[Morphometric analysis of the palpebral fissure in patients with thyroid-related disfunction before and after application of botulinum toxin].

Introduction: Botulinum toxin is an alternative treatment for retraction of ocular thyroid related dysfunction. The aim of this study was to evaluate the effects of this medication on upper lid position, levator palpebrae superioris muscle function and corneal exposure.

Methods: Seven patients were enrolled into the study.
