A constant‐force pocket probe is constructed by application of a constant‐force spring. This is wound on two cylinders in reverse‐winding mode. As the distance to the probe top is constant, a constant force is obtained. Very little experience is needed to master the rotating of the handle while using the probe.

Uveal melanoma is the most frequent primary intraocular cancer in adulthood and is mostly localised to the choroid. It can be treated using radiation therapy, laser therapy, local resection and enucleation, with the best results achieved by combining these procedures. However, up to half of patients develop metastatic disease. There are no efficacious treatment methods for patients in advanced stage or with metastasis. In recent years, several novel treatment modalities aimed at improving tumour control and reducing adverse events have emerged. This review summarises current clinical treatment methods and new therapeutic perspectives for uveal melanoma.
