Facts and Figures from the Ohio Amblyope Registry

 

  Figure 1 (below) shows the number of amblyopic children who have registered with the Ohio Amblyope Registry over the past 10 calendar years (2000-2009).  For example, in 2009 a total of 1,994 amblyopic children in Ohio signed-up to participate in the Ohio Amblyope Registry.

Figure 2 (below) shows the number of amblyopic children participants in the Ohio Amblyope Registry per year of age at the time of registration.  Most children register with the Ohio Amblyope Registry at 5 and 6 years of age.

Figure 3 (below) shows the percentage of amblyopic children participants in the Ohio Amblyope Registry per year of age at the time of registration.  About 76% of amblyopic children register with the Ohio Amblyope Registry by 6 years of age (inclusive).

Figure 4 (below) shows the age when amblyopia was first diagnosed in children who participate in the Ohio Amblyope Registry during the past 10 years (2000-2009).  As shown in Figure 4, the greatest number (known as the mode) of children diagnosed with amblyopia occurred at 4 years of age.  The average (known as the mean) age of all the amblyopic children who registered with the Ohio Amblyope Registry was 4 years 8 months.

Figure 5 (below) shows the number and percentage of amblyopic children in case management over the past 10 years (2000-2009).  Families of children in case management receive regular phone calls, letters, news letters, free treatment supplies (e.g., eye patches) and other services to help increase the success of maintaining eye doctor appointments and success of treatment and cure of the amblyopia.

Figure 6 (below) shows the race, based on parental self reports, of amblyopic children participants in the Ohio Amblyope Registry over the past 10 years (2000-2009).  The category of "Other" typically involved mixed or multiple races.  169 respondents declined to provide race information (i.e., Blank).

Figure 7 (below) shows the percentage of amblyopic children with a certain race, as reported on Ohio Amblyope Registry application forms for the past 10 years (2000-2009).

Figure 8 (below) shows the number of amblyopic children who were undergoing patching therapy for amblyopia at the time of registration with the Ohio Amblyope Registry in 2009.  The vast majority of patients, 1769 out of 1877 (95%) were undergoing patching therapy at the time of enrollment.

Figure 9 (below) shows who discovered the child's amblyopia (2009).  In 49% of the cases, the amblyopia was found by an eye doctor during a routine eye exam.  In 19% of cases, the amblyopia was discovered by a Pediatrician during a Well Child check-up or other type of exam by a Pediatrician.  In 13% of the cases, the amblyopia was discovered by a vision screening, usually undertaken by school personnel.  In 3% of cases, a nurse found the amblyopia during a vision screening other health exam or other health check-up.  In 13% of cases, "other" was reported when asked about who discovered the amblyopia.  Figure 10 addresses this "Other" category.

Figure 9. 

 

Figure 10 (below) shows the breakdown of the "Other" category when parents were asked who discovered the amblyopia (see Figure 9).  Most, 196 out of 241 (81%), reported that a family member discovered the amblyopia, usually because of the child eyes were "wondering" or misaligned.  37 out of 141 (15%) reported that the child's amblyopia was discovered because of another medical condition; during another type of health exam the amblyopia was discovered.

Figure 11 (below) shows how parents found-out about the Ohio Amblyope Registry in 2009.  The vast majority of parents, 1768 out of 1851 (96%), said that they found-out about the Ohio Amblyope Registry from their eye doctor.

Figure 11.

 

Figure 12 (below) shows the type of Eye Doctor that the amblyopic patient has based on parental reports (2000-2009).  Note that there are two types of Ophthalmologists; Medical Doctor (MD) and Osteopath (DO).  Optometrists are ODs.  301 of the respondents didn't know what type of eye doctor their child was seeing and 69 left the item blank on the registration form.  Overall, 69% of amblyopic children were seeing an Ophthalmologist, either an MD or DO, 24.1% were seeing an Optometrist and the remaining (6.9%) either didn't know what type of eye doctor their child was seeing or left the question blank.
