INDIAN PEDIATRICS 406 VOLUME 41APRIL 17, 2004 the literature (Medline Search), we found that retinal detachments are a known complication of chronic renal failure, though majority of case reports and series are from adult patients. Numerous hypothesis have been suggested for retinal detachments-dilutional hyponatremia(2), severe hypertension(3), ischemic infarction of choroids(4) and choroids s...

BACKGROUND/AIMS Choroidal thickness measurements are reported to differ between spectral-domain optical coherence tomography (SD-OCT) and swept-source OCT (SS-OCT). The aim of this study was to assess the comparability of choroidal thickness measurements using SS-OCT and SD-OCT devices among normal participants. MATERIALS AND METHODS This was a prospective study of 31 (62 eyes) normal partici...

Purpose Müller cells create the external limiting membrane (ELM) by forming junctions with photoreceptor cells. This study evaluated the relationship between focal photoreceptors and RPE loss in geographic atrophy (GA) and Müller cell extension into the subretinal space. Methods Human donor eyes with no retinal disease or geographic atrophy (GA) were fixed and the eye cups imaged. The retinal...

PURPOSE Several studies have convincingly shown that in chicks, compensation for imposed focus involves immediate changes in choroid thickness. The molecular events associated with choroidal thickening and the regulation of the choroidal response are largely unknown. METHODS Form-deprivation myopia was induced in the right eyes of 2-day-old chicks by the application of translucent occluders f...

The purpose of this study was to determine the effect of optical correction on the best-corrected visual acuity (BCVA) and subfoveal choroidal thickness (CT) in the eyes of children with anisohypermetropic amblyopia. Twenty-four anisohypermetropic amblyopic eyes and their fellow eyes of 24 patients and twenty-three eyes of 23 age-matched control children were studied. After one year of optical ...

Microvascular changes during the development of follicles in bovine ovaries were studied by scanning electron microscopy of corrosion casts. A clear vascular plexus of ovarian follicles appeared at the stage when secondary follicles were 200-400 microns in diameter. The plexus consisted initially of a thin, roughly structured and single-layered capillary network. During follicular development, ...

OBJECT Malignant progression of choroid plexus papillomas has been occasionally reported, but this issue has not yet been systematically addressed. METHODS Frequency and extent of malignant progression were examined in a retrospective series of 124 primary choroid plexus papillomas using uniform histological criteria. RESULTS After gross-total resection and a mean follow-up period of 59 mon...

The choroid plexus produces cerebrospinal fluid and plays an important role in brain homeostasis both pre and postnatally. In vitro studies have suggested that cells from adult choroid plexus have stem/progenitor cell-like properties. Our initial aim was to investigate whether such a cell population is present in vivo during development of the choroid plexus, focusing mainly on the chick choroi...
