Purpose:To evaluate the visual outc ome after direct laser photocoagulation of the worm in patients with early-stage diffuse unilateral subacute neuroretinitis(DUSN).Meth-ods:We report on four patients with D USN diagnosed in its early stage,in whom the worm was i dentified and de-stroyed by laser photocoagulation.Results:In all the four cases,resolution of the inflammato ry multifocal lesions was achieved within 1month of treatment .After that period and during follow-up(mean 11.5months),visual acuity im-proved in three eyes and remained unchanged in one eye.Conclusion:The diagnosis of DUSN in its early stage fol-lowed by prompt location and destruction of the worm by photocoagulation may improve visio n of affected patients.
Purpose: To evaluate the visual outc ome after direct laser photocoagulation of the worm in patients with early-stage diffuse unilateral subacute neuroretinitis (DUSN). Meth-ods: We report on four patients with D USN diagnosed in its early stage, in whom the The worm was dentified and de-stroyed by laser photocoagulation. Results: In all the four cases, resolution of the inflammasome multifocal lesions was achieved within 1month of treatment. After that period and during follow-up (mean 11.5 months), visual acuity im-proved in three eyes and static unchanged in one eye. Conflusion: The diagnosis of DUSN in its early stage fol-lowed by prompt location and destruction of the worm by photocoagulation may improve visio n of affected patients.
