| dc.description | Amblyopia when it is undetected can affect children in many ways, which can lead to amblyopic children having difficulties in coping when compared to their peers. Refractive amblyopia is the commonest cause of amblyopia in the Gaza strip and can be addressed successfully with patching therapy. However, its pattern and the impact of patching treatment on visual functions and binocularity among the children in the Gazan population is under-reported. These require to be addressed so that a better understanding and services can be provided. This study aimed to determine the pattern of refractive amblyopia and evaluate the impact of patching treatment on different visual functions, binocularity among Gazan children. This was an experimental study. Amblyopic children aged 4 to 12 years old who attended the Children's Unit at Gaza Ophthalmic Hospital from September 2019 until March 2020 were recruited. A purposive sampling method was used. All participants underwent a comprehensive eye test. Those who failed the test and were diagnosed with refractive amblyopia were offered to participate in the study. Two hours of daily patching was prescribed for 12- 17 weeks. After patching therapy was completed, visual and binocularity functions such as visual acuity, accommodation, stereopsis, contrast sensitivity and colour vision were assessed. The Amblyopia Treatment Index (ATI) was conducted. Of the 107 recruited refractive amblyopes, about two-thirds were female (57.9%), and the mean age was 7.85±1.55 years. Unilateral amblyopia cases were predominant (60.7%). Moderate amblyopia was commonly (81.8%) seen. A total of 149 amblyopic eyes were examined all together, with mean Best Corrected Visual Acuity (BCVA) 0.45±0.19 LogMAR (0.2 to 1.3 LogMAR) and the mean spherical equivalent (SE) +0.76±4.51D (-10.25D to +11.50D). Astigmatism was the most common cause of amblyogenic factors (46.7%). Among 24 amblyopes, their visual functions and binocularity improved significantly after receiving patching therapy. Visual acuity improved to 0.21±0.19 LogMAR and mean of 2.4 lines improvement. Contrast sensitivity improved to 1.69±0.22 LogCS with a mean difference of -0.38±0.34. Stereopsis improved to 2.03±0.36 log10 arcsec with a mean difference of 0.4 log10 arcsec. Lag of accommodation was the commonest. Changes in the accommodation were 0.81±1.06 with a mean difference of -0.45±0.86. Colour vision was normal in our amblyopes. The total median of ATI score was 3.00±0.90. In conclusion, refractive errors are still a high-risk factor of amblyopia among children in the Gaza strip even though it is avoidable, so early vision screening programs can contribute to solving the problem. Also, 2 hours of patching treatment had a significant impact on most of the visual functions and binocularity. Nevertheless, the score of the ATI questionnaire revealed that there is no clinically significant impact of patching on the child when considering various baseline characteristics.,Ijazah Sarjana Sains Kesihatan (Optometri) | - |
