ABSTRACT
Background: Macular edema is the major cause of decreased vision in patients with diabetes. Antioxidative and anti-inflammatory effects of photobiomodulation (PBM) have been reported with near-infrared irradiation. Objective: In this study, the efficacy and safety of PBM with near-infrared radiation in a patient with diabetic macular edema were assessed. Methods: We present the case of a 60-year-old man with diabetic macular edema responding to 670 nm light PBM alone. Results: After PBM, his vision improved and macular edema resolved on optical coherence tomography (OCT) findings without adverse events. In 16 months follow-up, visual acuity remained stable and OCT showed no evidence of recurrence of edema. Conclusions: Six hundred seventy nanometers light PBM can be potentially considered as a therapeutic method in diabetic patients with macular edema. Also, it provides a noninvasive and nonexpensive treatment in home.

ABSTRACT: Visual impairment due to refractive errors and color vision deficiency (CVD) can affect the visual abilities of workers in workplace. Identifying the prevalence of common visual problems helps us to prevent and treat occupational ocular problems.This study was conducted on 2600 males referring from companies for a routine medical exam to Occupational Medicine Center. In all subjects, visual acuity and refraction were measured. Assessment of color vision was performed by Ishihara color test. In present study, right eyes of subjects were selected to statistical analysis.The mean spherical equivalent was -0.19â±â1.39 diopter with a range of -11.00 to +10.00 diopter. Whereas 71% of persons were emmetropic, 20% and 9% of them were myopic and hypermetropic, respectively. From a total subjects, 164 of them had CVD with prevalence of color blindness of 6.3%. In comparison with normal subjects, CVD had no significant effect on refractive findings of our subjects (Pâ>â.05).Our data present the prevalence of refractive errors and color blindness among Iranian industry-workers. Compared with other studies, our subjects have a lower prevalence of refractive errors, and similar rate of prevalence of color blindness.

OBJECTIVES: In recent years, there has been an increasing amount of study on early diagnosis of kidney injury through sensitive and specific biomarkers. We examined the practical applicability of the urinary levels of NAG (N-acetyl-ß-D-glucosaminidase), AP (alkaline phosphatase), and LDH (lactate dehydrogenase) as renal dysfunction screening biomarkers in full and pre-term newborns treated with gentamicin. MATERIALS AND METHODS: Fourteen pre-term and fifteen full-term newborns who received gentamicin for suspected infections were enrolled. Serum and urine specimens were obtained before the zero days and after gentamicin infusion on the 1st, 3rd, and 5th days of treatment. RESULTS: In full-term newborns a significant increase in urinary NAG, LDH, AP after 5 days of gentamicin administration compared with control group was noted (P<0.05, P<0.001 and P<0.01; respectively). CONCLUSION: Our findings indicate that urinary enzymes may be useful in full-term newborns as a non-invasive method for evaluation of tubular function.
