We demonstrated that nematode larvae can be removed successfully from the central retina using vitrectomy techniques. By that means the damage to the visual functions can be limited. Near the posterior pole surgical extraction of the worm may be favorable compared to photocoagulation.

A monosymptomatic, intracorneal, granulomatous infiltration is very rare and has not previously been described in a case of lattice corneal dystrophy. This may have been a case of xanthogranuloma or sarcoidosis. Strangely, the granuloma occurred only several months after PTK; nevertheless, a pathogenetic connection seems unlikely.

For hemorrhagic subretinal lesions of diameter > 10 degrees a relevant reduction of central scotoma size is achieved by surgery. The final benefit for the patients depends on the frequency of surgical complications and neovascular recurrence.

Since there is no effective therapy, attention must be paid to preventive aspects. Improved information and awareness concerning the serious functional consequences of macular injuries is necessary, especially for non-medical users. Due to distinctive technical conditions (experimental arrangement with unprotected laser beam, comparatively high laser energy, prevailing parallel laser radiation), this circle of laser-users has a high risk of accident. A proper opportunity for an improved education are workshops for laser safety precautions.
