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.
