Dear Editor,

We thank the authors[1] for critically analyzing our manuscript tilted “Retinal Neovascularization And Its Regression On Doxycycline In Epidemic Retinitis”.[2]

We would first like to clarify that the optical coherence tomography (OCTA) scans are en-face scans and not cross-sectional scans. These were chosen to depict the extent of retinal neovascularization (rNV) on a horizontal plane. We however agree that the cross-sectional optical coherence tomography (OCT) are at different levels. Those were used as a reference for segmentation. The regression of rNV is, however, better appreciated on an en-face OCTA scan. We would also like to add that no deep capillary plexus (DCP) or choriocapillaris slab were provided in the figure due to extensive artifacts and shadowing.

We also agree and would re-iterate that rNV in epidemic features is rare but not unknown or unreported.[3] The case depicted here is of a young 22-year-old male where rNV was detected on OCTA. The patient did not have any other risk factors or features for microangiopathy making epidemic retinitis the most likely cause of rNV.

We agree with the authors that a fundus fluorescein angiography (FFA) would have provided extra information. However, being a retrospective report, this was not available. Also, the treatment criteria for epidemic retinitis is not clearly defined.

In conclusion, we believe that this report depicts a rare case of epidemic retinitis with rNV which regressed with doxycycline along with regression of retinitis.
