Background/aims To investigate retinal sensitivity and fixation stability using microperimetry in children with retinopathy of prematurity (ROP).
Methods Observational case series. Totally 51 preterm children who had been followed for ROP were examined in three groups (n=17 in each group). The groups were defined as children without ROP (group 1), children with spontaneously resolved ROP (group 2) and children who had laser treatment for ROP (group 3). All subjects underwent a detailed ophthalmic examination. Macular Analyzer Integrity Assessment Microperimetry was used to analyse macular light sensitivity and fixation stability. The results were compared between groups. The measurements were also analysed according to age, gender, birth weight and gestational age.
Results The mean age was 10.84±0.97 years, and 27 children were female. Mean average threshold (AT) for macular sensitivity was 25.5±2.1 decibel in group 1, 26.8±3.8 decibel in group 2 and 26.3±3.0 decibel in group 3. These differences were not statistically significant between the groups (p=0.067), but AT was abnormal in 29% of the whole study population. Outputs about fixation stability were similar between the three groups but fixation was unstable in 27% of the subjects. Mean AT was better in children ≥11 years old compared with the younger ones (p=0.022).
Conclusion Preterm children may have some abnormalities in macular light sensitivity and fixation stability. These abnormalities may be more prominent in children less than 11 years old. ROP itself or the laser treatment seems not to affect macular light sensitivity and fixation stability.
