Duane's Syndrome duane's syndrome duane's retraction syndrome is an eye movement disorder characterizedby a failure of the 6th cranial nerve to develop normally. http://www.angelfire.com/pa3/babyland/duanesyndrome.html
Extractions: Duane's Syndrome Duane's Syndrome is a congenital abnormality involving the innervation of the eye muscles. It most commonly occurs as an isolated event. It affects girls more than boys and the left eye more often than the right eye. Most commonly the eye does not turn out well (Type I), next most common is the condition where the eye does not move in or out (Type III), and last is the condition there the eye does not move in (Type II). In my opinion, the most commonly accepted indications for surgery in individuals with Duane's Syndrome is when the eye is crossed in straight ahead gaze, or when the person has to turn the head significantly in order to fuse the two eyes and eliminate double vision. None of the standard surgical options improve the ability of the eye to turn out much....the goal is generally to eliminate the crossing in primary position or to eliminate the head turn. As you know Duane's syndrome is a condition that affects the movement of one eye. The eyelid opening may also change during certain positions of gaze. The syndrome is caused by poor development of one of the nerves that controls eye movement. Fortunately, most children do very well. Most children do not require surgery. This condition does require regular monitoring of the vision by an experienced ophthalmologist to make sure the child is not developing a lazy eye. If the child is developing a lazy eye (poor vision) than surgery to correct the position of the eye is indicated. As you mentioned, surgery may also be indicated if there is a significant head turn.

Amy, child Mitchell, 8/13/99 MI Pablo has been recently diagnosed with Duane's Retraction Syndrome. For the past 3 yrs we thought he had a lazy eye. We even tried patching it. Now his Dr has realized it is this syndrome which basically means no peripheral vision. We don't anticipate any difficulties because of it. It's just a little detail I'll have to make sure his teacher understands. His OT believes this has contributed to his visual-spatial delays. He is still behind in fine motor development.

Extractions: Patients with DRS have intermittent binocular stimulation and reduced stereoacuity. To test the possibility that Duanes patients have reduced numbers of binocular neuroens we tested their monocular and binocular contrast sensitivity in comparison with matched controls. Paradoxically, we found increased levels of summation in the Duanes patients. We believe that this was due to decreased monocular sensitivity, particularly in the deviating eye, combined with normal binocular sensitivity. Ithese findings were reported at ARVO 2000 and have been submitted for publication to IOVS. Another interesting aspect of our findings is that Duanes patients showed a specific loss of contrast sensitivity at high spatial frequencies (> 10 cpd). We wonder whether normal binocular development is needed for high-spatial frequency channels. Moorfields Eye Hospital and the Applied Vision Research Centre.

Extractions: Department of Ophthalmology, Children's Hospital of Trieste, Italy Duane's Retraction Syndrome (DRS) is a neurogenic brainstem ocular motor dysfunction so named because of the retraction of the globe (caused by synchronous contraction of the horizontal recti) and narrowing of the lid fissure that occur on attempted adduction. DRS may be bilateral (15 - 20% of cases). By using EMG examination, this syndrome can be classified into three types (Huber, 1974, Brit. J. Ophthalmol., : 293-300): I) Palsy of abduction with retraction on adduction. EMG shows absence of electrical activity in the lateral rectus muscle on abduction but paradoxical electrical activity on adduction. II) Palsy of adduction with retraction, and intact abduction. EMG reveals electrical activity with contraction of the lateral rectus muscle on both abduction and adduction. III) Palsy of adduction and abduction, with retraction on attempted adduction. The EMG demonstrates co-contraction of the horizontal recti on both adduction and abduction. Because the EMG is not easily applicable to paediatric patients, other instrumental examinations like eye movements recording have been proposed. As shown by Metz (1975

Extractions: Duane's syndrome (type I) is made up of three parts: an inability to move an eye laterally away from the nose with widening of the eyes (palpebral fissure), retraction of the eye when attempting to look close or towards ones nose; and retraction of the eye. In the picture above the left eye can not look left while in the picture below, the eye moves back in the socket with narrowing of the aperture of the eyes. There are two other uncommon types of Duanes: Duane II where by the eye has trouble looking toward the nose (opposite to Duane's I); and Duane III made up of a combination of I and II. A patient with Duane's is likely to have an eye turn inwards at distance. It may be confused with a paralysis of the muscle which causes the eye to turn outwards (lateral rectus) resulting in an unnecessary neurological workup. Duane's is usually congenital and may be associated with other congenital disorders. It was originally thought to be due to fibrosis of one the eye muscles, today we know it is due lack of development of the nucleus (control center in the brain) of the sixth nerve. Interestingly, most of these patients do not have diplopia (double vision) on lateral gaze. Surgery should not be performed unless there is a cosmetic problem when looking straight ahead. A simpler solution than surgery is special glasses with prism to eliminate the head turn. Some of these patients have secondary convergence problems, which are effectively treated by vision therapy.

Paediatric specialist of doctorinternet answer to your query is as follows: " Baby waining starts at 6 months of age. In addition to his milk, you should give some orange juice and smashed vegetables well kooked. Also some mashed soup. There are many baby food available in the market at this age. Babies after 9 months must start to take regular meals 3 or 4 times a day. Meals must include carbohydrates like potatoes, smashed grains, bread, pasta and vitamins in the form of vegetables, fruits and fresh juices. One meal must contain some type of proteins like fish or meat, eggs and dairy products. Again, all these must be taken in addition to milk." All the best and enjoy good health. Doctorinternet.

Extractions: *Department of Ophthalmology, Faculty of Medicine, Siriraj Hospital, Mahidol University ABSTRACT : The purpose of this study is to determine the incidence, type, indication and result of surgery of Duane's retraction syndrome in Siriraj Hospital. The authors retrospectively analyzed the records of patients in muscle clinic between March 1, 1985 to March 31, 1998. Thirty-one cases of Duane's retraction syndrome were diagnosed. Duane's retraction syndrome type I is the most common (80%). Cases are more common in females (1.2 : 1). Majority of cases are unilateral. Amblyopia is detected in 16.13% of all cases. Most of indications for corrective surgery is the angle of deviation exceeds 20 A (prism diopters) or there is abnormal head position. The satisfactory outcome is found in Even though Duane's retraction syndrome is a rare con dition but the precision of the diagnosis is essentially important in order to detect amblyopia and correct abnormal head position.
