üRetinal vein occlusion can follow inadvertent photocoagulation o of a retinal vein. Rarely, there may be loss of central acuity from inadvertent pho photocoagulation of the fovea. üVitreous haemorrhage can follow photocoagulation of retinal or choroidal vessels. üThere may be visual field restriction, decreased contrast sensitivity, night vision or impaired colour vision. üVisual field constriction may impair fitness to drive although ophthalmologists increasingly strive to avoid this most undesirable problem, for example by avoiding confluent laser burns. üHeadache can sometimes follow laser therapy. The headache is usually relieved with rest and simple analgesia. Glaucoma must be excluded if the headache is severe or persistent.
