Objective: Analyze clinical data, therapy and tomographic parameters of patients attended at Fundação Hilton Rocha. Methods: This essay is a retrospective study based on a random sample of 150 patients submitted to cornea tomography and previous segment (Pentacam – Oculus, Wetzlar, Germany) at Fundação Hilton Rocha in the year 2015. The patients were classified as carriers or suspects of keratoconus through the following parameters: pachymetry, anterior and posterior central elevation, Ambrosio Relational Thinnest (ART), value of D and keratometry. After […]

Objective: Treatment with anti-angiogenic drugs is one of the most widely used modalities of treatment of macular edema related conditions. Intravitreal injection of a VEGF-A inhibitor is highly effective, but is related to adverse effects such as increased intraocular pressure. The objective of this study was to evaluate intraocular pressure (IOP) variation in patients who underwent intravitreal injections of ranibizumab, variation according to phakic/aphakic and history of previous injections. Methods: This was a cross-sectional observational study. All patients submitted to […]

Posterior scleritis is an ocular inflammatory disease that affects the sclera e whose diagnosis is difficult. The main clinical manifestations are worsening of visual quality, ocular pain and finding in the posterior segment, such as serous retinal detachment, choroidal folds, optic disc edema and sclera thickening. We should award for systemic findings, because it is often accompanied by rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease and infections, such as syphilis and tuberculosis.This paper aims to describe two cases: one […]

Multiple myeloma (MM) leads to disorderly proliferation of plasma cells clones, producing monoclonal immunoglobulin and commonly presents osteolytic lesions. In some cases, however, masses called plasmocytomas are found. Ocular and orbital involvement is unusual in this pathology. In this paper, we describe a case of a 63 year-old patient with previous diagnostic of MM that evolved an intraconal plasmocytoma in the right eye, as well as a vascularized mass in the anterior chamber from uveal infiltration. These lesions were correlated […]

The methanol toxicity is considered rare event , especially when taken by inhalation . It was portrayed in the present study a case report of a patient who developed toxic optic neuritis after exposure to methanol and acetic acid by inhalation in the workplace . It was described for the therapies from the literature as well as the clinical manifestations and management in this patient.

To report the case of a patient with vaso-occlusive retinopathy due to systemic lupus erythematosus (SLE) associated with antiphospholipid antibody syndrome (APAS), which started with signs and symptoms of autoimune hemolytic anemia accompanied by sudden monocular visual loss. Few cases of SLE manifestation primarily involving ocular changes have been reported in the Brazilian and international literature. Screening for antiphospholipid antibodies is of the greatest importance for patients with lupus retinopathy, so that immediate therapy with anticoagulants may be instituted in […]

The pseudoxanthoma elasticum is a generalized disease of the connective tissue involving the skin, eyes and cardiovascular system triggering the fragmentation and calcification of elastic fibers. Usually occurs after puberty, the manifestations characteristics are small spots, circumscribed, yellowish, located on the neck, axilla and inguinal folds. Angioid streaks in the retina, tendency to hemorrhage and arterial insufficiency are the most common complications. This disease can be inherited as autosomal dominant or recessive. The treatment of ocular manifestations is through the […]

Particle Swarm Optimization (PSO) is an artificial intelligence technique (AI) that can be used to find approximate solutions to numerical problems of maximization and minimization. In this study, it was used a PSO algorithm to compare displacements from human cornea sample subjected to internal pressure of 45 mmHg with Results of numerical simulations were provided which identified optimized values for hyperelastic properties of the cornea (µ and α). By means of the results from numerical simulations via inverse analysis by […]
