Physical effects and cognitive function after exercising "Rue-si-dad-ton" (exercise using the posture of the hermit doing body contortion): a randomized controlled pilot trial.

Background: This study aims to preliminarily evaluate effect on physical properties of shoulder joints and cognitive function after practicing Rue-si-dad-ton, a Thai traditional exercise using the postures of the hermit doing body contortion which still lacks systematically conducted evidence-based regarding its benefits.

Material And Method: Thirty-seven participants who have routinely worked on computer at least 3 hours per day were recruited and randomized into intervention (n = 19) or control group (n = 18). Physical effect on shoulder joints was evaluated by measuring shoulder range of motion (ROM) and evaluating shoulder function with the American Shoulder & Elbow Surgeons Standardized Shoulder Assessment Form.

Enhanced depth imaging spectral-domain optical coherence tomography of the choroid in Thai population.

Objective: To examine subfoveal choroidal thickness (SFCT) in Thai population using enhanced depth imaging spectral- domain optical coherence tomography (EDI-OCT) and to study its correlation with foveal retinal pigment epithelium thickness (FRPE), central neurosensory retinal thickness (CNRT), age, and refraction.

Material And Method: Four hundred eighty eyes from 240 subjects without glaucoma, retinal, or choroidal diseases underwent scanning of the retina and choroid using EDI-OCT SFCT FRPE, and CNRT measurements were based on the 1:1 micron images and wereperformed by two independent observers. The reliability ofmeasurements between the observers was evaluated by intraclass correlation coefficient (ICC).

Classification and regression tree analysis for predicting visual outcome after open-globe injuries in Siriraj Hospital.

Objective: To create a model for predicting visual outcome after open-globe injuries by using data of Siriraj Hospital.

Material And Method: Retrospective data of patients presented with open-globe injuries between January 2007 and December 2010 were used to create prognostic model. Seventeen factors at initialpresentation were collected and evaluated to develop the model by mean of Classification and Regression Tree analysis (CART).

Optic atrophy after anti-vascular endothelial growth factor injection in diabetic patients with proliferative diabetic retinopathy.

Objective: To study the prevalence of optic atrophy in patients with proliferative diabetic retinopathy (PDR) who underwent intravitreal bevacizumab injection and risk factors associated with optic atrophy.

Material And Method: A retrospective case control study enrolled 269 cases (394 eyes) of patients with PDR, in which 166 cases (219 eyes) received intravitreal bevacizumab injection. Associated factors such as type of DM, hemoglobin A1c level, hypertension, hypercholesterolemia, chronic kidney disease, previous intravitreal surgery retinal detachment, and vitreous hemorrhage were recorded.

Visual outcome and prognostic factors in posterior segment intraocular foreign bodies.

Objective: To identify the prognostic factors that predict visual outcome in eyes with penetrating ocular injuries with retained intraocular foreign bodies (IOFBs).

Design: Retrospective cases series

Material And Method: The authors reviewed the records of 228 patients who had penetrating eye injuries with retained posterior segment IOFBs managed at Siriraj Hospital between June 1995 and February 2008. One hundred and forty-one patients (61.

Nonmydriatic digital retinal images for determining diabetic retinopathy.

Objective: To evaluate the efficacy of nonmydriatic digital retinal images for determining diabetic retinopathy.

Material And Method: Single field 45-degree digital retinal images of 225 eyes from 142 diabetic patients were obtained with a nonmydriatic camera. The images were diagnosed and graded by a general ophthalmologist.
