Created 2010-01-14 11:19:33 by คุณ System Administrator 269 Views

A prospective descriptive study was conducted to determine the ability of non ophthalmic personnel in eye screening program for young children (3 years ? 6 months) from three Kindergartens in Hat-yai district. Ninety-four (26.3%) out of 358 children were signed out for by their parents. Eighty nine children or 24.9% were examined by ophthalmic personnel while ninety one (25.4%) children were examined by a non ophthalmic group. Between January 2003 and January 2004, ninety four children (49 boys and 45 girls) were subjected to eye examination. The average ages were 3.3 ? 2.7 years. The mean refractive error (retinoscopy) in the right and left eye were -0.2 ? 0.5 diopters and -0.3 ? 0.4 diopters, respectively. The cut point of visual acuity test (LEA test) was Log Mar > 0.4. The sensitivity of results for ophthalmic personnel revealed 57.1% in contrast to 85.7% to the non ophthalmic group. Specificity test showed 93.9% for the former, and 90.2% for the latter. The positive predictive values were 44.4%, 42.9% and the negative predictive value were 96.3%, 98.7% respectively. The eye screening program for young children can therefore be done by non ophthalmic personnel.

Objective : This retrospective study analyses the post-operative results of the surgical procedure for upper lid trichiasis. Surgical technique : Most of the cases were operated on by segmental lid splitting at the grey line, and covering the extent of all trichiatic lashes. Then, the anterior lamella was shifted upward and fixed against the posterior lamella with full-thickness mattress suture(s). Patients and Methods : Eighteen eyelids of 15 patients were performed the described operation in Rajavithi hospital during November 4, 1998 and June 25, 2003. The results revealed that four (26.67%) of 15 cases were male, the mean age was 63.13 years, and the average follow-up time was 144 days. The procedure was successful in 14 of 18 eyelids (77.77%), with success being defined as no lashes touching the globe. The main causes of failure were surgical technique (11.11%) and the linkage of the control of the underlying etiology (11.11%). Conclusion : This lid split procedure for correction of upper lid trichiasis is simple, free of complication and provides good functioning and cosmetic results.
