PURPOSE
To report long-term changes in the average retinal nerve fiber layer (RNFL) thickness in 2 patients who had intravitreal bevacizumab (IVB) injection for diabetic papillopathy. CASE SUMMARY: A 36-year-old patient with diabetes complained of decreased visual acuity (20/200) in the right eye. The fundus examination showed optic disc swelling in both eyes. The average RNFL thickness based on optical coherence tomography (OCT) increased to 278 microm and Goldmann perimetry showed nasal visual field defect in the right eye. The IVB was injected into the right eye. Three weeks after the IVB injection, RNFL thickness decreased to 135 microm and visual acuity improved to 20/25 in the right eye. However, RNFL thickness increased from 126 to 207 microm and visual acuity decreased to 20/32 in the left eye. Thus, IVB was injected into the left eye. In week 3, RNFL thickness decreased to 147 microm and visual acuity improved to 20/20 in the left eye. At 12 months after IVB injection, RNFL thickness was 87 microm in the right eye and 109 microm in the left eye. A 57-year-old patient with diabetes complained of decreased visual acuity (20/200) and showed optic disc swelling in the right eye. The average RNFL thickness increased to 252 microm and Goldmann perimetry showed an enlarged blind spot in the right eye. IVB was injected into the right eye. After 3 weeks, RNFL thickness decreased to 136 microm and visual acuity improved to 20/70 in the right eye. Six months after IVB injection, RNFL thickness was 83 microm in the right eye. CONCLUSIONS: Visual acuity progressively improved within 3 weeks and RNFL thickness measured by spectral domain OCT showed progressive thickness reduction in 2 cases of diabetic papillopathy patients who had IVB injections. |
