Predictive value of visual evoked potentials, relative afferent pupillary defect, and orbital fractures in patients with traumatic optic neuropathy.

Background: The purpose of this study was to determine the predictive value of flash visual-evoked potentials (VEP), relative afferent pupillary defect, and presence of orbital fractures in patients with traumatic optic neuropathy.

Methods: A prospective study was conducted in 15 patients with indirect traumatic optic neuropathy. All patients underwent a thorough ophthalmic examination.

Therapeutic effect of macular grid photocoagulation in treatment of nonexudative age-related macular degeneration.

Background: To investigate the effect of prophylactic subthreshold laser macular grid photocoagulation on drusen area and to evaluate the visual outcome and incidence of choroidal neovascularization in patients with soft drusen maculopathy.

Methods: In a nonrandomized nonmasked clinical trial, 18 patients (36 eyes) with bilateral soft drusen maculopathy were studied. For each patient, one eye was treated with 48 subthreshold (invisible end-point) applications of 532-nm KTP-laser in a macular grid pattern and the fellow eye was observed.
