Bilateral Angle Closure Glaucoma In A Teenage Girl

Primary angle closure glaucoma (PACG) usually presents as unilateral and has acute onset. To the best of our knowledge, chronic PACG in very young age is rare. We share a case report of a teenage girl with advanced glaucomatous changes and, on gonioscopy, had synechia and closed angle of anterior chamber. She was treated by bilateral laser iridotomy and topical glaucoma medication. As patient had poor control of IOP on medications in right eye , she underwent filteration surgery in right eye. The author concludes that, even at very young age, in the absence of predisposing factors for secondary glaucoma, the patient should be investigated for PACG and managed accordingly

Comparative Study Of Visual Reaction Time And Field Of Vision In Deaf Children With Normal Children

With auditory deprivation the visual senses are enhanced in the deaf children. The visual reaction time is measured by response analyzer and the field of vision is tested by Priestly-Smith's perimeter in the deaf children and compared with the normal hearing children in the age group of 8-16 years. The results showed significant increase in the VRTand field of vision in the deaf children as compared to the normal children. Early deafness is responsible for processing the visual stimuli in auditory cortex due to plasticity of neuronal cells in the auditory cortex. The deaf depend on the visual stimuli to judge three dimensional objects as well as to moving stimuli in the periphery. The deaf children show faster VRT and widening of field of vision due to continuous training by sign language. Visual experiences to the deaf children improve the neuronal circuitry involved thus providing evidence of auditory plasticity.

A Case of Xanthoma Disseminatum Accentuating over the Eyelids

Xanthoma disseminatum (XD) is a rare, benign non-familial mucocutaneous disorder, which is a subset of non-Langerhans cell histiocytosis. It is characterized by mucocutaneous xanthomas in a disseminated form typically involving the eyelids, trunk, face, and proximal extremities and occurs in flexures and folds such as axillae and the groin. Mucosal involvement of the respiratory or gastrointestinal tracts may lead to hoarseness or intestinal obstruction from a mechanical mass effect. This paper outlines the case of a 47-year-old female with progressive yellow-to-brown confluent nodules and plaques of various sizes on her scalp, face, oral mucosa, neck, shoulder, axillary folds, and perianal area. Xanthomas accentuating over the eyelids and eyelashes led to partial obstruction of her visual field and interfered with blinking. Further, she suffered from xerophthalmia. The presentation of histopathological features including foamy histiocytes, inflammatory cells, and Touton giant cells in conjunction with her clinical findings indicated a diagnosis of XD. Evaluations for extracutaneous involvement including the central nervous system, respiratory tract, gastrointestinal tract, and bone resulted in nonspecific findings. Although she has been treated with surgical excisions, CO2 laser therapy, and oral prednisolone, new lesions are still emerging.

Development of noncontact thermometer / 医疗卫生装备

The thermopile used to measure infrared energy from body radiation, a medical noncontact thermometer is developed in this paper. The thermometer, which can be applied to practices, adopts chop amplification, environment temperature compensation, ??24bit ADC and multilayer optical drawtube.
