Background: The visual and refractive status were assessed for grade 7 students in seven governorates in Oman. The health records were reviewed to assess the rationale for their previous school-based vision screening. Methods: A representative sample of 7th grade students with a refractive error (RE) was examined by optometrists in 2012. Their compliance with spectacle wear was also reviewed. Each student's vision and refractive status in grades 1 and 4 were compared with the status in grade 7. Each student's use of eye care services between grade 4 and 7 was evaluated to determine the uptake of existing eye services for vision problems. Results: This study had 286, 7th grade students with RE (myopia [94%], hyperopia [4%] and astigmatism [>1D] [2%]). The types of RE between genders in each grade were not significant (P > 0.05). During their vision screening when they were in grade 4, 5 of 13 moderate myopes (>-2D to - 6D) and 3 of 4 high myopes (>-6D) were detected and managed. Ten students with moderate and high myopia were already using spectacles before they were screened in grade 7. The compliance for spectacle wear was 62% in grade 7. Between grades, 4 and 7, 140 (49%) students did not visit eye clinics or an optician. Conclusions: Refractive services in grade 4 were an additional initiative from the eye health care systems in Oman to the actual World Health Organization recommendations of conducting vision screening and RE corrections at grade 7 and 10. However, this was not proved to be significantly effective in early detection, and even the uptake of eye care services by school children was also low. [ABSTRACT FROM AUTHOR]

Calcinosis cutis involves the inappropriate deposition of calcium within the dermis layer of the skin and is often associated with autoimmune diseases. A 3-year-old healthy Omani child presented for evaluation of asymptomatic hard nodule on the left upper eyelid. Pathological examination identified the mass as subepidermal calcified nodule. The patient had no history of trauma or metabolic disturbances. Serum levels of calcium and phosphate were normal. Idiopathic calcinosis cutis should be included in the differential diagnosis for eye lid mass. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the normal conjunctival flora and to ascertain their sensitivity to antibiotics. Materials and Methods: Prospective study was undertaken with 56 patients scheduled for cataract surgery. In each of these patients, conjunctival swab was taken from both eyes before instilling any antibiotic drops or local anesthetics and were sent for culture sensitivity by inoculating the samples in blood agar plates. The un-operated eyes served as controls for the study. The results were tabulated and analyzed by applying confidence intervals at 95% confidence limits. Results: Of the 112 eyes studied, positive cultures were obtained from 54 eyes (48.3%) preoperatively, and included both operated and control eyes. Coagulase-negative staphylococcus was isolated in 44 eyes (81.5%). Maximum sensitivity was found with vancomycin, gentamycin, chloramphenicol, and ciprofloxacin and maximum resistance with fusidic acid, penicillin, and oxacillin. Conclusion: We conclude that coagulase-negative staphylococcus are the most common bacteria isolated from the conjunctival sac, and vancomycin followed by gentamycin and ciprofloxacin are most effective against normal conjunctiva l flora, and fusidic acid the most ineffective of all the antibiotics tested.
