The paper is a continuation of the previous paper with the same title published in ROJ, 2015; 8 (2): 14-20, which focused on theoretical issues of topometry and dosage/anatomical planning of proton radiation of intraocular targets and presented technical aspects of the development of a special radiation installation for proton therapy of intraocular malignant neoplasms. The present paper discusses positioning issues, i.e. exact placement of the target (tumor) with regard to the dosage distribution field envisaged by the treatment plan. The paper describes the unit supplied with a positioning system aligning the eye with the proton beam: it traces the location of the eye during irradiation and stops the dose delivery if the eye is misplaced // Russian Ophthalmological Journal, 2016; 2: 11-17. doi: 10.21516/2072-0076-2016-9-2-11-17 .
