Ocular abnormal head posture (AHP) or torticollis is a frequent sign in pediatric pathology The incidence is 5.6% in ophthalmological practice and 3.19% in pediatric ophthalmological practice. The abnormal head posture is adopted to improve visual acuity maintain binocular single vision, center residual visual field with the body or for cosmetic reasons. Face turn is the most frequent abnormal head posture in pediatric ophthalmology. The more common diseases causing face turn are Duane syndrome, congenital fibrosis of extraocular muscles, nystagmus, refractive errors, visual field defects. The most frequent ocular causes of head tilt in children are congenital nystagmus, superior oblique paresis, dissociated vertical deviation, Brown syndrome, refractive errors. Chin-up or chin-down abnormal head postures are most commonly caused by "A" and "V"-pattern strabismus, palpebral ptosis, nystagmus, refractive errors. Torticollis is not a diagnosis, but it is a sign of an underlying disease. There are ocular diseases which diagnosis is straightforward for general practitioner, pediatricians or pediatric surgeons (horizontal nystagmus, lateral rectus paralysis, ptosis, esotropia), but others less obvious (superior oblique paralysis, Duane syndrome, A and V-pattern strabismus, torsional nystagmus) because of the compensatory head posture, and these last disorders are predisposed to confusion with congenital AHP Interdisciplinary collaboration between ophthalmologist, pediatrician, pediatric surgeon, ENT specialist and neurologist is mandatory in establishing the etiology of AHP Every child with AHP must be examined by an ophthalmologist.

Congenital/developmental cataract is a significant cause of blindness in children worldwide. Full knowledge of clinical features is essential for early diagnosis and proper treatment to prevent irreversible visual impairment. We conducted a retrospective chart review on 520 congenital/developmental cataract cases based on a five-year clinical data from Eye and ENT Hospital of Fudan University, Shanghai, China. Clinical features including age at the surgery, chief complaints, interval between initial identification of cataract-related manifestations and surgery, etc. were summarized. 56.3% of children were bilateral. The age at surgery ranged from 0.25 to 17.4 years, only 9.2% receiving surgery below 1 year. Interval between initial identification of manifestations and surgery ranged from 2 days to 17 years. Concomitant congenital abnormalities were present in 67 patients, with persistent hyperplastic primary vitreous and congenital heart disease as the most frequent ocular and systemic disorders. Strabismus and nystagmus were seen in 20.6% and 11.9% of patients. In bilateral cataract patients with strabismus, axial lengths of esotropia-affected eyes were statistically shorter than exotropia-affected eyes. These findings provide information on characteristics of congenital/developmental cataract in China and may assist in achievement of comprehensive treating strategies in these cases.
