| Sumario: | Objective: To study per-papillary retinal nerve fibre layer (pRNFL) and central macular thickness (CMT) changes
in adults with hyperopic anisometropic amblyopia using optical coherence tomography.
Study Design: Cross sectional study.
Place and Duration of Study: Combined Military Hospital, Lahore, Pakistan, from Oct 2019 to Feb 2020.
Methodology: In this study 30 adults, 18-40 years of age were included who presented in our clinic with monocular poor vision. They underwent detailed ophthalmic clinical examination: including corrected and uncorrected distance visual acuity, slit lamp bio-microscopy and fundus examination with 90 diopter lens. After fulfilling criteria of anisometropic amblyopia, central maular thickness (CMT) and per-papillary retinal nerve fibre layer (pRNFL) thickness was measured by using RS-3000 SLO, NIDEK Co, Japan spectral domain optical coherence tomography device and compared the central maular thickness (CMT) and per-papillary retinal nerve fibre layer (pRNFL) thickness in amblyopic and fellow eye of same individual.
Results: The mean change in per-papillary retinal nerve fibre layer (pRNFL) thickness in amblyopic eyes, 121.48
± 4.90 μm and non amblyopic eyes was 112.92 ± 4.72 μm with statistical significance (p<0.001). The mean change in central macular thickness (CMT) in amblyopic eyes was 198.50 ± 5.30 μm and non amblyopic eyes was 206.80 ± 3.11 μm with statistical significance (p<0.001). There was significant increase in per-papillary retinal nerve fibre layer (pRNFL) thickness and significant decrease in central macular thickness (CMT) on comparing the amblyopic and the fellow eyes of the same patients.
Conclusion: Central macular thickness (CMT) decreased......................... |
