Investigation of the Paediatric Tracheostomy Decannulation: Factors Affecting Outcome

Introduction: Evidence for factors determining paediatric tracheostomy decannulation vary extensively; therefore, this prospective observational study aimed to investigate these factors.   Materials and Methods: In total, 67 consecutive paediatric patients (<12 years old) who referred to the Department of Otolaryngology, (Postgraduate Institute Medical Education and Research),(Chandigarh), ...

Prandial presbyopia.

Loss of accommodation amplitude during eating (prandial presbyopia) is a rare phenomenon that has been reported in only 1 patient who had had head trauma. We report 2 patients who had not had head trauma and whose accommodative amplitudes, measured by dynamic retinoscopy, became markedly diminished within 1 minute of starting a meal and did not recover for 55-60 minutes. Apart from this abnorma...

Optic nerve hypoplasia and astigmatism: a new association.

Thirty-one patients with optic nerve hypoplasia (ONH) or septo-optic dysplasia and two patients with segmental ONH underwent retinoscopy. The results were compared with those of 20 normal subjects. There was a higher prevalence of astigmatism in the patients than in the controls. Two patients with segmental ONH had no evidence of astigmatism. The association of astigmatism with ONH has not hith...

A Comparison of Lens and Skiascope Methods in Retinoscopy with Undilated Pupils.

The eyes of young chickens grow toward emmetropia.

The distribution of refractive errors was followed in chicks from hatching to 8 weeks of age. A dramatic progressive decrease in the variability of refractions was observed over this period. In addition, there appeared to be a parallel decline in hyperopia, even when the artifactual hyperopia of retinoscopy was taken into account. These results are evidence for a postnatal development regulator...
