  • Diagnostic vitreoretinal surgery should be considered when other noninvasive methods of diagnosis have failed to establish a pathoetiologic mechanism.

  • The goals of ocular biopsy should be to acquire microbiological, cytologic, histologic, immunologic and genetic information, with minimum surgical trauma, for modifying and directing medical and surgical treatments.

  • The development of a 25-gauge operating system introduces a new concept in vitreous, retinal and choroidal biopsy.

  • Vitreous, retinal or choroidal biopsy are relatively safe procedures, and the results often change clinical management.

  • 25-gauge procedures induce minimal ocular trauma, decrease the inflammatory response, and may allow faster overall patient recovery.
