Three-years follow-up swept source optical coherence tomography angiography findings in post-fever retinitis

Abstract

Post fever retinitis (PFR), characterized by multiple cotton wool spot like lesions in the posterior pole, is commonly reported following viral and bacterial infections. Retinal perfusion defects have been documented with the help of optical coherence tomography angiography (OCTA) in cases of PFR. But long term changes in such cases have not been reported earlier. In the following report, we have described the swept-source OCTA findings of two PFR patients at initial presentation and three years follow-up. Initial OCTA scans may not provide accurate information regarding the perfusion status due to associated retinal edema and inflammation. However, persisting perfusion defects at the superficial and deep retinal capillary plexus were noted on long term follow-up in both the cases.

Epidemic retinitis - Factors associated with poor visual outcomes

“…It is now known that the retinitis lesions after resolution leave behind capillary non-perfusion areas which are permanent. [ 16 17 ] A case from Group A in our study supported these findings, and in addition, demonstrated partial reperfusion of vasculature after 6 years [ Fig. 2 ].…”
