neck shoulder Discomfort due to visually demanding experimental near work is influenced by previous neck pain task duration astigmatism internal Eye Discomfort and accommodation
PLOS ONE, 2017Co-Authors: Camilla Zetterberg, Mikael Forsman, Hans O RichterAbstract:Visually demanding near work can cause Eye Discomfort, and Eye and neck/shoulder Discomfort during, e.g., computer work are associated. To investigate direct effects of experimental near work on Eye and neck/shoulder Discomfort, 33 individuals with chronic neck pain and 33 healthy control subjects performed a visual task four times using four different trial lenses (referred to as four different viewing conditions), and they rated Eye and neck/shoulder Discomfort at baseline and after each task. Since symptoms of Eye Discomfort may differ depending on the underlying cause, two categories were used; internal Eye Discomfort, such as ache and strain, that may be caused by accommodative or vergence stress; and external Eye Discomfort, such as burning and smarting, that may be caused by dry-Eye disorders. The cumulative performance time (reflected in the temporal order of the tasks), astigmatism, accommodation response and concurrent symptoms of internal Eye Discomfort all aggravated neck/shoulder Discomfort, but there was no significant effect of external Eye Discomfort. There was also an interaction effect between the temporal order and internal Eye Discomfort: participants with a greater mean increase in internal Eye Discomfort also developed more neck/shoulder Discomfort with time. Since moderate musculoskeletal symptoms are a risk factor for more severe symptoms, it is important to ensure a good visual environment in occupations involving visually demanding near work.

Eye and neck shoulder Discomfort during visually demanding experimental near work
Work-a Journal of Prevention Assessment & Rehabilitation, 2012Co-Authors: Camilla Lodin, Mikael Forsman, Hans O RichterAbstract:Frequent use of digital information technology has an impact on Eye- and neck/shoulder-Discomfort. Studies with cross sectional and intervention design indicate an association between the two symptom categories. Still, whether visually demanding near work, per se, contributes to increased neck/shoulder Discomfort remains a question of debate. The aim of this laboratory study was to assess if visually demanding experimental near work affects Eye- and neck/shoulder-Discomfort when the posture was adjusted for comfort and no movements were allowed. Thirty-three healthy subjects performed a visually demanding computer screen task (viewing task) under four different optical lens conditions: binocular -3.5 D and monocular -3.5 D, +3.5 D and ±0 D. During the experiment subjects were seated in an office chair (with neck support) that was individually adjusted for comfort. At baseline and after each viewing task, subjects reported their perceived Eye- and neck/shoulderDiscomfort on Borg’s CR-10 scale. Results show a significant increase of Eye Discomfort between baseline and the first viewing task, and a significant increase in neck/shoulder Discomfort from baseline throughout the first three viewing tasks. Further analysis is required to determent whether the neck/shoulder Discomfort was induced by the demanding near work or the static posture, or a combination.

Obstructive sialadenitis of a transplanted submandibular gland: chronic inflammation secondary to ductal obstruction
british journal of ophthalmology, 2014Co-Authors: Su Jia-zeng, Yang Ning-yan, Liu Xiao-jing, Cai Zhi-gang, Lv Lan, Zhang Lei, Wu Li-ling, Liu Deng-gao, Ren Wen-ge, Gao YanAbstract:Aims To determine the pathological basis and clinical features of obstructive sialadenitis in transplanted submandibular glands (SMGs). Methods A total of 161 patients (174 Eyes) with keratoconjunctivitis sicca underwent microvascular SMG transplantation. Patients were followed up at approximately 1 and 4 months and annually thereafter. Clinical data, including dry Eye Discomfort, symptoms of ductal obstruction, and Schirmer test, were recorded. Sialography was performed in six patients. In addition, SMG autotransplantation was performed in 22 rabbits. Salivary flow was recorded and the morphology of glands was examined at 6 months postoperatively by light microscopy. Results Among the patients, 16 out of 172 glands during the latent period (0-3 months) and 2 out of 154 glands with long-term follow-up (>1 year) showed obstructive sialadenitis. Typical manifestations were continuous small volumes of viscous secretions, recurrent gland swelling, decreased Schirmer test values, and irregular dilation of the main duct on sialography. The transplanted SMGs eventually showed no secretion in five cases. Of the 22 rabbit SMGs, 4 had obstructive sialadenitis. Morphological examination showed chronic inflammatory infiltration with salivary deposits. Conclusions Obstructive sialadenitis of transplanted SMGs is a chronic inflammation secondary to ductal obstruction, which leads to insufficient ocular lubrication and potential treatment failure.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000345284300013&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701OphthalmologySCI(E)PubMed3ARTICLEgyyu@263.net121672-16779

long term follow up after submandibular gland transplantation in severe dry Eyes secondary to cicatrizing conjunctivitis
American Journal of Ophthalmology, 2010Co-Authors: Maria Borrelli, Christina Schroder, John K G Dart, John Richard O Collin, Peter Sieg, Ian A Cree, Melville Matheson, John M Tiffany, Gordon ProctorAbstract:Purpose To evaluate the long-term results of autologous submandibular gland transplantation in Eyes with cicatrizing conjunctivitis and to determine biomechanical and biochemical features of the resulting salivary tear film. Design Prospective, observational case series. Methods Fifteen Eyes with cicatrizing conjunctivitis with a viable autologous submandibular gland transplantation were compared with 10 Eyes with cicatrizing conjunctivitis and a failed submandibular gland transplantation or no submandibular gland transplantation. Best-corrected visual acuity, frequency of tear substitute instillation, severity of dry Eye Discomfort, lid margin erythema, conjunctival hyperemia, corneal epithelial edema, tear film break-up time, Schirmer test results, and corneal fluorescein and conjunctival Rose Bengal staining were evaluated. In a subgroup central corneal thickness and sensitivity, corneal epithelial barrier function, conjunctival and lid margin flora, and conjunctival impression cytologic analysis results were evaluated. In 3 patients, preoperative and postoperative tear samples were analyzed for viscosity, surface tension, and presence of mucins. Results Submandibular gland autotransplantation resulted in long-term improvement of subjective, objective, and some ocular surface parameters. Salivary mucins were detectable in salivary tears after submandibular gland transplantation. The viscosity of salivary tears was more similar to normal saliva and the surface tension was intermediate between the 2 original secretions. Conclusions Submandibular gland autotransplantation provides long-term relief from pain and reduces the need for frequent installation of lubricants.
