Corneal Burn Caused by Carbon Dioxide Ultrapulsed Laser for Nevus Removal

PURPOSE: Periocular carbon dioxide ultrapulsed laser surgery can induce ocular damage. Herein we report a rare case of corneal burn after carbon dioxide ultrapulsed laser for nevus removal. CASE SUMMARY: A 25-year-old female patient presented with ocular pain, decreased visual acuity, and metamorphopsia in the left eye after laser surgery for nevus removal at a dermatology clinic 4 days prior. The patient's best corrected visual acuity in the left eye was 20/100. Central corneal haziness and corneal epithelial defect were observed on biomicroscopic examination. Antibiotics, steroid and artificial tear eye drops were administered for treatment. Glasses were prescribed to correct refraction errors. After 2 months of treatment, the best corrected visual acuity in the left eye recovered to 20/50, and corneal epithelial defect was mostly healed, however corneal haziness remained. CONCLUSIONS: Carbon dioxide ultrapulsed laser is commonly used in dermatological treatments. The use of an eye shield is important during this procedure, and possibility of ocular surface damage from laser treatment should be considered.

IMPROVED METHODS APPLIED IN THE NEONATAL BLUE LIGHT EYE TREATMENT / 现代医院

Objective To explore the effect of the application of the modified eye shield in neonatal phototheraphy . Methods 120 neonates with jaundice were chosen and randomly divided into two groups (60 each).Control group was only applied to normal eye shield, while the improved group used the modified eye shield, wrapping with gauze, and then mositen the eyes with 1~2 Tobramycin eye drops on each side.Both groups were fixed with 3M tapes.After a 24 -hour photothera-py, the incidence rate of reseola, skin rash and eye secretions were compared.Results The improved group has better pro-tective effect and the difference between these two groups is of great statiscally significance(p<0.05).Conclusion The ap-plication of modified eye shield could effectively protect their eyes from neonatal roseola, skin rash and eye secretions, im-prove the feeling of comfort and promote high quality nursing service .
