The aim is to study the efficacy of 2 hours of daily patching for treating moderate amblyopia in children aged 4 to 9 years.
20 children aged 4 to 9 years who have moderate amblyopia (visual acuity between 0.2 to 0.5) participated in the study. They
receive 2 hours of daily patching combined with 1 hour of near visual acuity activities during patching.
The visual acuity in the amblyopic eye improved from baseline to 4 month by 2.5 lines. The 4 month visual acuity was at least 0.65 and improved from the baseline by 3 or more lines in 65% of children. The visual acuity improved by 2 or more lines in 80% of children.
It could be concluded that 2 hours of daily patching combined with 1 hour of near visual acuity activities during patching is effective in treating moderate amblyopia in children aged 4 to 9 years.
Aim: To study the efficacy of collagen crosslinking on pseudophakic bullous keratopathy.
Methods: Fifteen patients with pseudophakic bullous keratopathy participated in the study.
Corrected visual acuity measurement, slit lamp examination, corneal
clarity grading, ocular
pain intensity scale and corneal thickness measurement were performed before corneal
crosslinking and 1, 3 and 6month postcrosslinking. Corneal collagen crosslinking was
performed after the removal of the epithelium and the application of riboflavin every 3
minutes for 30 minutes then the ultraviolet irradiation applied for 30 minutes with the
application of riboflavin every 5 minutes.
Results: The mean age was 65.5 year (9 females and 6 males). Corneal thickness
decreased significantly after crosslinking but the visual acuity did not change significantly
after crosslinking. Corneal transparency improved in the first month. Ocular pain
decreased significantly in the first and third month.
Conclusion: Corneal collagen cross linking is an effective and temporal procedure to
decrease ocular pain for bullous keratopathy patients
