Background and Aim: Considering  appropriate  different  ways  and  views  between  optometrists  and  ophtalmologists  about  time  of  patching  the  safe  eye , it  was  nessary  to  performe  an  investigation  about  this  subject . The  main  purpose  of  this  investigation  was  to  compare  two  methods  of  part  time  and  full  time  patching  to find the  least  effective  time  in  treatment  of  nonstrabismic and moderate  amblyopia. 

Materials and Methods: The  present  study  was  based  on  clinical  experiments and  the  tests  were  done  by  Autorefractometer, Retinoscope, Ophtalmoscope  and  Broken wheel . There were 4565 children in screening test. About  80  amblyopic  children  aged between  3-7  years  old  were  selected  from 125 cases  with the problem of amblyopia . Periodical exams were done monthly. Independent T, dependent T, regresion, and Fisher’s Exact Tests were for statistical analyses (SPSS 18).

Results: Eighty  amblyope  children  were  classified  in  2  groups  of  closing  safe  eye  in  full  time  or  part  time  patching. The difference of visual acuity was measured before and after treatment. There was not any statistical difference between 2 groups (p=0.293).

Conclusion: Considering  statistical  results , the  extent  of  improvement  was  equal  between  these  2  groups  and   there  was not  any  meaningful  difference  between  them.  So,  it  would  be  concluded  that  in order to prevent  unwanted  side effects  of  closing  the  safe  eye, an appropriate method  for   treatment of  unstrabismic  amblyopia may be  the  part  time  patching.       

Key words: Amblyopia,  Full time patching , Part time patching , nonstrabismic and moderate amblyopia
