Difference of anterior and posterior orbital development in patients with congenital microphthalmia: a retrospective cohort study from China.

Aim: To evaluate volume differences between anterior and posterior orbit and demographic characteristics of Chinese patients with congenital microphthalmia.

Methods: A retrospective cohort study, involving 169 unilateral congenital microphthalmia patients aged between 1 and 57 years old was conducted. Three-dimensional images of the orbit were generated from past CT scans, and digital orbital volume comprehensive measurement was done.

Congenital Monocular Strabismus Fixus.

Purpose: To investigate the clinical characteristics and magnetic resonance imaging (MRI) findings of the extraocular muscle and ocular motor nerves in congenital monocular strabismus fixus.

Methods: The retrospective observational case series of three patients with congenital monocular strabismus fixus were reviewed between January 1, 2006, and December 31, 2016. Ophthalmologic examination and thin-sectioned MRI of the ocular motor nerve and the orbit were performed on the three patients.

[Vertical retraction syndrome caused by anomalous orbital structures].

Objective: To described the clinical feature and MRI imaging of six children with vertical retraction syndrome.

Methods: Six children with unilateral vertical retraction syndrome between 15 months and 8 years of age, mean age was (5.01 ± 1.

[Correlation between upper airway soft tissue 3-D measurement and the severity of obstructive sleep apnea hypopnea syndrome].

Objective: To investigate the correlation between upper airway CT measurement value and severity of patients with obstructive sleep apnea hypopnea syndrome (OSAHS).

Methods: The upper airway of 82 patients with OSAHS were scanned by CT during normal respiration. The 3-D CT measurement were made in lateral and anterior-posterior diameters, cross-section areas and volumes of retropalatal and retroglossal region.

[Theoretic explanation about visual disorder induced by fibrous dysplasia of skull: pressure disequilibrium between lamina cribrosa].

Objective: To investigate the causes for changes in optic nerve head and visual impairment caused by fibrous dysplasia (FD) of optic canal stenosis.

Methods: A total of 12 FD patients, diagnosed by CT, received the fundus and optical coherence tomography (OCT). Those with FD involving optic canal underwent decompression.
