Ovid: Duane's Ophthalmology

چکیده
Although technologic advances have permitted quantitative insights into nystagmus analysis, the clinician should not be daunted. Many useful, often diagnostic, observations can be made by physical examination alone. Figures 1 and 2 are examples of one convenient method of diagramming nystagmus. Also, nystagmus can be further described when the globes are inspected under slit-lamp magnification or when the fundus is viewed. However, due to the complexity of nystagmus waveforms and the possibility of combinations of different types of nystagmus, only ocular motility recordings can guarantee diagnosis that is both accurate and repeatable.

Congenital inverse Duane's retraction syndrome: A rare presentation
A 12-year-old girl presented with esotropia and face turn since birth. Ocular motility examination showed restricted abduction associated with down shoot and retraction on attempted abduction characteristic of inverse Duane's retraction syndrome. To the best of our knowledge, this is one of the very few reported cases of congenital inverse Duane's retraction syndrome.

The occurrence from birth of copious lacrimation on eating in some patients with Duane's syndrome suggests that both are caused by dysgenesis or a lesion in the vicinity of the abducens nucleus in the pons.
متن کاملMotion perception tested with reversing grating in Duane's syndrome.
Many papers have reported that motion perception asymmetry (MPA) is replaced by motion perception symmetry (MPS) by the 4th to 5th month after birth, when stereopsis starts to occur in normal infants. Duane's syndrome is a congenital motor abnormality, it does, however, reportedly show good stereopsis. We confirmed the stereopsis in Duane's syndrome and checked the motion perception (MP) by usi...

PURPOSE To study the neuroanatomic characteristics of patients with Duane's retraction syndrome with high-resolution magnetic resonance imaging. METHODS The study included 11 consecutive cases, including five patients with type I, one patient with type II, four patients with type III, and one patient with inverse Duane's retraction syndrome. The patients underwent magnetic resonance imaging o...
متن کاملDuane's retraction syndrome.
DUANE'S retraction syndrome (Duane, 1905) is frequently but not invariably associated with convergent strabismus when the eyes are in the primary position (Duke-Elder, 1964); if a head-turn is present, it will be in the direction of action of the paretic lateral rectus muscle. In the atypical retraction syndrome, the medial rectus is more paretic than the lateral rectus muscle; there is exophor...
