IntroductionOcular tuberculosis (TB) encompasses a broad spectrum of clinical manifestations affecting different structures of the eye. It is caused by Mycobacterium tuberculosis, a great ancient organism that induces various types of diseases and unfavorable outcomes if unrecognized and not well treated.PurposeTo report the clinical profile of 34 ocular TB cases observed during 6 years period in Hospital Universiti Sains Malaysia (HUSM).MethodA retrospective review of medical records from 34 patients diagnosed with ocular TB in HUSM from January 2011 until December 2016.ResultsThe mean age was 43 ± 14.6 years old. Both male and female affected in about 1:1 ratio. The majority of subjects were local Malays (91.2%). Risk factors included previous contact with pulmonary TB patients (38.2%), and patients with underlying diabetes mellitus (26.5%). Most patients showed normal chest radiography (79.4%). However they had positive Mantoux test (94.1%) and raised erythrocyte sedimentation rate (ESR) value (58.8%). Uveitis was the most common ocular manifestation of ocular TB (70.6%) while the rare ocular manifestations included optic perineuritis and optic neuritis, orbital apex syndrome, orbital cellulitis, sclerokeratitis, corneal ulcer and conjunctival abscess. All patients responded well to anti-TB treatment, but visual outcome was variable.ConclusionsThis review shows the diverse entity of ocular TB spectrum in an endemic area. Good clinical response to anti-tuberculous therapy supported the presumed diagnosis of ocular TB in majority of the cases.
Age-related macular degeneration (AMD) is an important cause of irreversible central blindness worldwide. Clinical manifestations range from asymptomatic in early and intermediate AMD to significant vision loss in late AMD. Approximately 10% of cases of early AMD eventually progress to the late advanced stage, influenced by the upregulation of vascular endothelial growth factor (VEGF). In this study, we evaluated VEGF concentration in the tears and serum of AMD patients. Our study revealed a significantly higher level of VEGF in the tears of patients with AMD compared with controls. The tear VEGF level has high sensitivity and specificity, and is significantly related to the severity of AMD, whilst serum VEGF level is non-specific and non-predictive of AMD severity. Thus, VEGF level in the tears may be used as a non-invasive biomarker for AMD progression. A large cohort study is needed for further verification.
Rhabdomyosarcoma (RMS) is the most common soft-tissue tumor in children, frequently affecting the nose, nasopharynx, and paranasal sinuses. RMS of this sinonasal region manifests with non-specific nasal symptoms of allergic rhinitis, sinusitis, or upper airway infection. Associated ocular symptoms are rare. We describe a young girl who presented with acute onset squint secondary to sinonasal RMS. Imaging showed an aggressive sinonasal tumor with oropharyngeal, intraorbital, and intracranial extension. Histopathological findings were consistent with a diagnosis of rhabdomyosarcoma, embryonal type. The patient deteriorated rapidly due to disease complications. We provide a literature review of pediatric sinonasal RMS with various manifestations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
