Microsurgical management of neovascularisation secondary to posterior segment ischaemia.

Structural, metabolic and functional rehabilitation of eyes affected by the haemorrhagic and tractional sequelae of neovascularisation secondary to posterior segment ischaemia is discussed. Microsurgical management must pay due attention not only to the mechanical but also to the underlying cell-biological implications of the surgical pathology. The appropriateness of case selection for surgery rests upon the likelihood of successful technical and functional outcomes and also upon the overall visual status of the patient, issues of particular relevance to diabetes.
