Purpose: To identify the predictors of final visual outcome in cases with post fever retinitis (PFR).Methods : This is a retrospective study of cases with diagnosis of post fever retinitis. Color fundus photograph and optical coherence tomography (OCT) parameters at presentation and final visit were analysed. Various factors at presentation [age, systemic illness, best corrected visual acuity (BCVA), area of retinitis and hard exudates, OCT parameters], at final visit (optic disc pallor, OCT parameters) and the treatment modalities used were correlated with BCVA at final visit.Results : Twenty four eyes of 16 patients with PFR were included in the study. Median BCVA at presentation was 6/60 and at final visit was 6/9. By multiple linear regression after adjusting for other variables, for every 1 unit increase in height of SRF at fovea at presentation, the value of final BCVA decreased by 0.001 unit. For every 1 unit increase in extent of EZ loss and subfoveal deposit height, the value of final BCVA decreased by 0.0001unit and 0.004 unit respectively.Conclusion: Height of SRF at presentation, extent of EZ loss and subfoveal deposit height at final visit were associated with poor final BCVA in PFR. |
