Introduction: Glaucoma patients are known to have optic disc cupping, leading to loss of retinal ganglion cell axons. This peripapillary nerve thinness is known to be associated with glaucoma in adult patients. Hence, we intended to evaluate the peripapillary and macular nerve fiber thickness in eyes of pediatric glaucoma suspects using spectral domain optical coherence tomography (OCT).
Methods: This cross-sectional analytical study included 44 eyes of 22 paediatric glaucoma suspects, who were compared with 40 eyes of 20 normal paediatric eyes. Pearson correlation coefficients were calculated to assess the relations between the peripapillary retinal nerve fiber layer (RNFL) thickness and ganglion cell complex (GCC). Receiver Operating Characteristics (ROC) curve was plotted for OCT parameters in both the groups along with area under the curve (AUC) calculation. P values < 0.05 were considered as statistically significant.
Results: We found the RNFL to be thickest in the superior, inferior, nasal and temporal quadrants in both glaucoma suspects and normal group. When compared among quadrants in RNFL, all the values in different quadrants were statistically significant from each other and in between groups with p < 0.01. The RNFL thickness was statistically different in glaucoma when compared with normal in superior, temporal, and nasal quadrants however, no statistically significant difference was found in inferior quadrant RNFL. The largest AUC for discrimination of glaucoma suspect eyes from normal in peripapillary RNFL in was nasal quadrant in right eye, followed by temporal quadrant whereas it was largest in superior followed by nasal quadrants then average in left eye. However, AUC for discrimination of glaucoma suspects from normal in GCC was poor.
Conclusions: Glaucoma suspect paediatric eyes showed significant thinning in peripapillary nerve fiber layer thickness compared to normal subjects.
