Directory of Open Access Journals Sweden. Ocorreu um caso de edema macular cistoide. To evaluate the features fundosvopia idiophatic vitreomacular traction syndrome VMT with ocular coherence tomography OCT – Stratus, before and after vitrectomy; to identify situations where ocular coherence tomography provides additional information on disease morphology and pathogenesis.
Comparative retinal ocular coherence tomography imaging was performed in four patients with different stages of vitreomacular traction syndrome. Standard-resolution ocular coherence tomography Stratus provides vitreous-retinal images that help the management and treatment of vitreomacular traction syndrome.
Standard-resolution ocular coherence tomography allows good visualization of the architectural morphology of the vitreous and retina in vitreomacular traction syndrome. It helps understanding its pathogenesis, planning. To evaluate de macular structural damage in Stargardt’s disease by optical coherence tomography, correlating with visual acuity and disease duration.
Patients with Stargardt’s disease were included and submitted fkndoscopia visual acuity logMAR measurement and complementary examinations performed were color fundus photographs, fluorescein angiography and optical coherence tomography. All cases were reexamined for diagnostic confirmation and the duration of symptoms was determined. The control group was composed of the same number of subjects, matched by sex and age, without any ophthalmologic alteration.
The duration of the disease varied from 3 to 21 years mean of Concerning the macular fundoscopka in optical. Exclusion criteria were diabetes, any macular pathology and unreadable optical coherence tomography or angiogram.
The angiograms were divided into three groups according to the edema intensity: The nine zones of the optical coherence tomography macular map were compared between the control and the three subgroups of the study group and, between group I and groups II and III. Full Text Available A maioria das fraturas dos ossos temporais resulta de traumas cranianos bruscos, de alta energia, estando muitas vezes relacionadas a outras fraturas cranianas ou a politraumatismo.
Histiocitoma fibroso benigno profundo: We present the computed tomography images of an year-old male patient with a deep benign fibrous histiocytoma at the lateral aspect of the left leg. Computed tomography images showed a well-defined mass with marked peripheral enhancement by iodinated contrast medium.
Only few reports of this rare soft tissue tumor can be found in the literature. Further, it evidenciated the correlation between the increase in foveal thickness and the reduction in visual acuity.
Levels of hemoglobin A1c did not influence the center direcya thickness data. An early detection of clinically significant macular edema leads fnudoscopia to a redefinition of the real meaning of incipient retinopathy and can prevent further significant reduction of vision. O estudo contou com 30 olhos como grupo controle. Acute appendicitis is the most important cause of abdominal pain requiring surgical intervention in the Western world. The early diagnosis of this disease is of paramount relevance for minimizing its morbidity.
Diagnostic difficulty is higher in children, the elderly, and women in childbearing age. The main imaging methods for evaluation of acute appendicitis are ultrasound and computed tomography. The present study is aimed at describing the disease physiopathology, commenting main computed tomography technical aspects, demonstrating and illustrating tomographic findings, and describing main differential diagnoses.
To evaluate the anatomy of idiopathic macular hole IMH using Optical Coherence Tomography OCT and to construct a prognostic index that can be correlated with the didecta outcomes and the anatomical closing. They presented calcifications in basal ganglia, dentate nucleus, subcortical region and semioval center, due to alteration in calcium metabolism or due to senile relative hypoxemic state. The image pattern was not strictly related with etiology, although some differences in dystrophic senile calcifications the only one present in semioval center and absent in subcortical region.
CT is an easy exam, has maximum sensitivity and allows diagnosis, contributing to early treatment of many etiologies of Fahr’s syndrome.
The purpose of this case report was to correlate optical coherence tomography findings and visual outcomes of patients with different degrees of commotio retinae.
A year-old male and a year-old male that presented with decreased vision due to Berlin’s edema after blunt ocular trauma were evaluated by optical coherence tomography and retinography. The ophthalmic examination showed traumatic uveitis and fundoscopy revealed mild retinal opacification in the first case and severe opacification in the latter. The optical coherence tomography confirmed the reduction of foveal depression on the first case and the disarrangement of all retinal.
Aspectos na tomografia computadorizada. Trauma is nowadays one dundoscopia the most common causes of death and traumatic thoracic lesions are important agravant to trauma patients. In this direfta the aspects of computed tomography from cases of thoracic trauma were studied. Macular edema is the leading cause of poor vision in diabetic patients. The mechanism of edema formation is complex and involves biochemical and structural changes.
The authors review fundoscopis update the direccta concepts related to diabetic maculopathy. To describe morphological features of the macula in patients with retinopathy of prematurity.
Twelve premature babies with retinopathy of prematurity grades I, II and III underwent dilated fundus examination and optical coherence tomography evaluation. In all thirteen eyes of the twelve premature patients optical coherence tomography revealed a condensed retinal pigmented epithelial layer in diercta macular -foveal area shown by increased reflectivity.
In these eyes the retinal layers were not well differentiated.
In premature patients with retinopathy of prematurity, optical coherence tomography revealed poorly differentiated layers in the macular region with increased reflectivity in retinal pigmented epithelial-choriocapillaris zone.
Os exames foram revisados por dois radiologistas, que estabeleceram os achados por consenso. To describe the high-resolution computed tomography findings in the lung of patients with systemic sclerosis, independently of the respiratory symptoms.
Seventy-three high-resolution computed tomography scans of 44 patients with clinical diagnosis of systemic sclerosis were reviewed and defined by the consensus of two radiologists. Abnormalities were seen in The most frequent findings were reticular pattern The lesions were predominantly located in the basal The author describes biochemical and structural effects of vitamins and antioxidants on the retina.
The main substances present in diet food and vitamin supplies involved in the genesis of age-related macular degeneration are shown. Also reports on the outcomes of prospective studies related to the subject, by literature review are presented. Most temporal bone fractures result from high-energy blunt head trauma, and are frequently related to other skull fractures or to polytrauma.
Fractures and displacements of ossicular chain in the middle ear represent some of the main complications of temporal bone injury, and hence they will be more deeply approached in the present article. Other types of injuries include labyrinthine fractures, dural fistula, facial nerve paralysis and extension into the carotid canal. Computed tomography plays a fundamental role in the initial evaluation of polytrauma patients, as it can help to identify important structural injuries that may lead to severe complications such as sensorineural hearing loss, conductive hearing loss, dizziness and balance dysfunction, perilymphatic fistulas, facial nerve paralysis, vascular injury and others.
