The indications for two types of pulsed Nd: YAG lasers in the treatment of vitreous pathology are reviewed. A series of 94 eyes from 93 patients were treated with the mode-locked system and 72 eyes from 71 patients were treated with the Q-switched system. A classification of vitreous pathology with prognostic value for the efficacy of treatment of both lasers is established. For the Q-switched laser the range of indications in the posterior pole is larger and fewer sessions are needed; however, complications are more frequent than with the mode-locked laser. This difference is due to the higher energy needed with the Q-switched laser to treat more severe vitreous pathology.
Three patients with Tolosa-Hunt syndrome were reported. All clinical investigations were negative in two of them, apart from the orbital venography, which showed on the affected side, an obstruction of the superior ophthalmic vein in its third segment. In the third case, early subclinical optic nerve involvement were demonstrated and followed up by visual evoked responses to checker-board pattern stimuli.
