Anti-VEGF agents including Aflibercept Ranibizumab and Bevacizumab has been the gold standard of treatment of neovascular age-related macular degeneration (nAMD) and are generally well tolerated. Brolucizumab has also been recently approved for treatment of nAMD based on data from Phase 3 Hawk and Harrier trials. Brolucizumab was found to be effective to maintain visual gains to week 96 but few serious ocular side effects has been reported in Feb 2020 by American society of Retina Specialists (ASRS).
| Case Report|| |
An 85-year-old diabetic female presented with complaints of blurred vision and floaters in her right eye 5 days after receiving the second dose of brolucizumab (BZM) injection. She had previously been treated with multiple intravitreal aflibercept injections in her right eye for neovascular age-related macular degeneration (nAMD) [Figure 1]a since her initial diagnosis in 2018, and her left eye was blind as a consequence of massive subretinal hemorrhage and vitreous hemorrhage resulting from an aggressive nAMD in the year 2015.

Retinal vessels and the mid-peripheral retina appear normal (b) Color fundus montage image 5 days after receiving BZM injection for neovascular AMD: Multiple retinal hemorrhages perivenous and scattered all along the retinal mid-periphery could be seen (arrow 1). Focal sheathing of retinal veins is evident as segmental, elongated patches of retinal whitening along the veins (arrow 2)|

At presentation, her best corrected visual acuity in the right eye was 20/200 and the left eye recorded no perception of light. Anterior segment examination on slit lamp of the right eye showed a posterior chamber intraocular lens; 1+ cells were seen in the anterior chamber, and +1 cells were seen in the anterior 1/3rd vitreous cavity. Left eye examination showed seclusion pupilla. Fundus examination of the right eye showed an irregular elevated grayish-white patch of retinal pigment epithelium irregularities with minute subretinal hemorrhages in the macular area, suggestive of neovascular AMD. Also, multiple retinal hemorrhages, mostly peri-venous and scattered all along the retinal mid-periphery, could be seen. Focal sheathing of retinal veins is evident as segmental, elongated patches of retinal whitening along the veins [Figure 1]b. Spectral domain optical coherence tomography (OCT) scan showed hyper-reflective tiny dots in the clear hypo-reflective vitreous space above the retina, suggestive of inflammatory cells. The presence of a thick irregular hyper-reflective lesion under the fovea, with associated retinal thickening and intra-retinal fluid, was consistent with nAMD [Figure 2]. Based on the typical clinical findings, she was diagnosed as a case of retinal vasculitis with intra-ocular inflammation induced by BZM, and she was started on oral and topical corticosteroids.

| Discussion|| |
Retinal vasculitis with or without intra-ocular inflammation with the use of BZM has been well reported in the western literature with an incidence rate of 4.6%. However, Chakraborty et al. reported no such case in their large study on an Indian population, hypothesizing the role of race and genetics as a likely cause for the absence of such a complication in an Indian scenario.
Our case highlights the development of such a potential serious complication in an Indian population as well. To the best of our knowledge, this is the first reported case of retinal vasculitis after receiving BZM in an Indian population. Narayanan R et al. have also reported a single case of intense ocular inflammation with hypopyon after intravitreal injection of BZM in a case of polypoidal choroidal vasculopathy. Although BZM has potential benefits and provides a 12 week duration in between treatments in patients with nAMD as compared to other standard anti-vascular endothelial growth factor (anti-VEGF) injections, this benefit comes with a potential risk of vision-threatening retinal vasculitis which has been rarely reported with other standard anti-VEGF therapies.
| Conclusion|| |
Physicians should be aware of such serious complications, and extreme caution is advisable in selection of BZM as a treatment option in one-eyed patients. Locally available standard of care anti-VEGF therapy should be considered for all one-eyed patients with neovascular AMD, and if BZM has to be used in rare situations, retinal vasculitis as a serious potential complication need to be discussed with the patients.
