Evaluation of dynamic stereopsis in intermittent exotropia patients.

Aim: To delineate the characteristics of the dynamic stereopsis test and analyze related parameters in intermittent exotropia [X(T)] patients.

Methods: Fifty-seven X(T) patients and 55 normal subjects were enrolled in this study. The normal and X(T) groups were used to test the reproducibility and reliability of the dynamic stereopsis test, and Bangerter filters with densities of 0.

[Quality of life assessment in children with congenital bilateral cataract].

Objective: To study the influence of congenital bilateral cataract on visual-related quality of life (QoL) in children.

Methods: The scale of QoL for children with congenital bilateral cataract was used to evaluate the QoL of 81 children with congenital bilateral cataract and 28 healthy children with normal visual acuity. The average age of congenital bilateral cataract candidates was 9.

Long-term visual outcome of dense bilateral congenital cataract.

Background: Dense congenital cataracts often cause severe visual impairment. The results of long-term follow-up of dense bilateral congenital cataract in China have not been well documented. The purpose of this study was to evaluate the long-term visual function in children who underwent cataract extraction for dense bilateral congenital cataract in southern part of China.

[Development and evaluation of the scale of quality of life for children with bilateral congenital cataract].

Objective: To develop and evaluate the 23-item quality of life (QoL) 125 scale contained four subscales for children with bilateral congenital cataract.

Methods: 18 children with normal visual acuity and 76 patients with congenital bilateral cataract (age range of 8 years to 15 years) were evaluated with QoL. The 23-item QoL scale contained the following subscales: visual function, self-care, sociality, and mentality.

[The clinical features and surgical treatment of masked bilateral superior oblique palsy].

Objective: To investigate the clinical features, diagnosis and the management of masked bilateral superior oblique palsy (MBSOP).

Methods: Retrospectively analyzed the records of all 7 patients that met the clinical criteria for MBSOP in Zhongshan Ophthalmic Center between 1999 and 2003. The head tilt, vertical deviation in primary position and the action of obliquus pre- and postoperatively were collected in detail.

[The effect of weakening the overaction superior oblique muscles on the status of ocular torsion].

Objective: To investigate the effect of weakening the superior oblique muscles on the status of ocular torsion.

Methods: Twenty-nine patients (58 eyes) underwent tenotomy or partial ectomy of bilateral superior oblique muscles for treatment of superior oblique overacting. Objective cyclodeviations were assessed by fundus photograph before and 7 days after the surgery.

[The effect of preventing anterior segment ischemia by preservation of anterior ciliary vessels in rabbit].

Objective: To investigate the effect of preserving anterior ciliary vessels (ACVs) on the prevention of anterior segment ischemia syndrome (ASI) during the surgery of extraocular muscles.

Methods: Thirty-two adult New Zealand white rabbits were randomly divided into four groups. ACVs of the right eyes were preserved among all of the rabbits, and were cut off in all of the left eyes.

[Clinical features of V patterns strabismus and its long-term effect of surgical treatment].

Objective: To investigate the features and treatment of V patterns strabismus.

Methods: Pre- and post-operative deviation and oblique muscle action as well as binocular visual function were evaluated in sixty-three V pattern patients. The difference between upgaze and downgaze of deviation were recorded before and after operation.

[The effect of weakening inferior oblique muscles on the status of ocular torsion].

Objective: To understand the clinical significance of subjective and objective examination of cyclodeviations and investigate the effect of weakening inferior oblique muscles on the status of ocular torsion.

Methods: Twenty patients (40 eyes) with overacting inferior oblique muscles underwent bilateral myotomy or partial myectomy of inferior oblique muscles. Subjective cyclodeviations were measured before surgery as well as one week, two months after surgery by double maddox rod test (DMRT).

[Clinical features and surgical treatment of A-pattern exotropia].

Objective: To investigate the clinical features of A-pattern exotropia and to evaluate the efficacy of surgical treatment for the correction of A-pattern exotropia (A-XT).

Methods: Pre- and post-operative eye position, superior oblique muscle function, clinical features and binocular function were examined and analyzed in 32 patients with A-pattern exotropia.

Results: Overaction of the superior oblique (SO) (31/32) and insufficiency of medial rectus muscle (20/32) were commonly seen in the group of patients.
