Vitreoretinal surgery revealed various posterior empty spaces. Understanding these spaces and fluid dynamics is crucial for successful surgical outcomes.

Area of Science:

  • Ophthalmology
  • Vitreoretinal Surgery
  • Surgical Anatomy

Background:

  • Vitreoretinal disorders necessitate complex surgical interventions.
  • Understanding the posterior segment's anatomy is critical for surgical success.
  • Intraoperative visualization of vitreoretinal relationships can be challenging.

Purpose of the Study:

  • To investigate the characteristics of intravitreal posterior empty spaces during vitreoretinal surgery.
  • To analyze how different posterior anatomical relationships influence these spaces.
  • To correlate surgical observations with vitreoretinal and posterior hyaloid dynamics.

Main Methods:

  • Observation of intraoperative anatomy in 151 eyes undergoing vitreoretinal surgery.
  • Categorization into groups based on retinal detachment presence (97 eyes with, 54 without).

  • Assessment of anatomical spaces with and without intraocular infusion fluid.

    • Main Results:

    • Identification of multiple types of posterior empty spaces: within the posterior vitreous, between hyaloid and retina, around isolated hyaloid, and between vitreous and attached hyaloid.
    • Demonstration that infusion fluid significantly alters the size and shape of these spaces.
    • Observation of dynamic changes in empty spaces due to fluid flux.

    Conclusions:

    • Multiple types of posterior empty spaces exist and are observed during vitreoretinal surgery.
    • Accurate interpretation of these spaces is vital for effective surgical conduct.
    • Intraoperative fluid dynamics can create artifacts, complicating the assessment of pre-existing vitreoretinal relationships.
