Relationship between Vision and Visual Perception in Hong Kong Preschoolers.

Purpose: Although superior performance in visual motor and visual perceptual skills of preschool children has been documented in the Chinese population, a normative database is only available for the US population. This study aimed to determine the normative values for these visuomotor and visual perceptual tests for preschool children in the Hong Kong Chinese population and to investigate the effect of fundamental visual functions on visuomotor and visual perceptual skills.

Methods: One hundred seventy-four children from six different kindergartens in Hong Kong were recruited.

Factors affecting accuracy in the Developmental Eye Movement Test measurement for Cantonese-speaking children.

Background: This study aims to determine the factors affecting the accuracy in the Developmental Eye Movement (DEM) test measurement for Cantonese-speaking children.

Method: The voices of 10 Cantonese-speaking children (aged between six and eight years) undertaking the vertical test (40 numbers) of the DEM test were recorded on a digital audio recorder. These voice clips were assessed by an experienced examiner to give the DEM test times.

The developmental eye movement (DEM) test and Cantonese-speaking children in Hong Kong SAR, China.

Background: There is no published norm for the Developmental Eye Movement (DEM) Test for Cantonese-speaking Chinese children. This study aimed to determine the normative values of this test for Cantonese-speaking Chinese children in Hong Kong SAR and to compare the results with the published norms of English-speaking and Spanish-speaking children.

Method: Cantonese-speaking students aged from 6 to 11 years were tested by the DEM test in Cantonese and a digital recorder was used to record the process.

Tuberculosis and wound healing in head and neck cancer.

Globalization of tuberculosis was noted, especially in immunomodulated patient. Patients having tuberculosis involving the cervical lymph nodes, undergoing resection for squamous cell carcinoma of the head and neck region would impact a detrimental effect to the surgery. We report 3 cases that had caused significant morbidity in post resection period.

Intra-observer and inter-observer repeatability of anterior eye segment analysis system (EAS-1000) in anterior chamber configuration.

Background: Anterior chamber configuration can be assessed via optical or ultrasonic techniques. Scheimpflug photography is a non-invasive method measuring the anterior segment. The Anterior Eye Segment analysis system, EAS-1000, utilises the Scheimpflug principle and was found to have good repeatability.

The effect of myelination on perimetry and retinal nerve fibre analysis.

BACKGROUND: Myelinated retinal nerve fibres around the optic nerve head can lead to an enlargement of blind spot with kinetic perimetry. Presumably extensive myelination will also decrease the visual sensitivity with static perimetry. This study reports the effect of myelination on static perimetry in several patients.

Reconstruction challenge--combined use of pectoralis major and gastric pull-up flaps for massive naso-oropharyngeal/oesophageal defects.

Massive defects of the upper aerodigestive tract present a reconstructive challenge. We report a case in which a large defect of the naso-oropharyngeal and oesophagus was reconstructed with a combination of a gastric pull-up and a pectoralis major muscle flap. Postoperative function was good and survival was in excess of 16 months.

Nasopharyngectomy for recurrent nasopharyngeal carcinoma: a review of 31 patients and prognostic factors.

Objectives/hypothesis: Nasopharyngectomy is a well-established treatment option for recurrent nasopharyngeal carcinoma. Over a period of 4 years and 3 months, in a total of 43 patients, 45 nasopharyngectomies were performed. Thirty-one patients with follow-up ranging from 12 to 58 months were studied.

Recurrent ameloblastoma presenting in the temporal fossa.

Recurrent ameloblastoma presenting in the temporal fossa is a rarely reported clinical entity. This report presents a case of temporal recurrence that occurred 30 years after the initial surgical treatment. A 45-year-old woman had a history of multiple enucleations for recurrences of her right mandibular ameloblastoma.
