Abstract Details

Purpose:

To report the changes in vitreolenticular and vitreoretinal interface after complicated and uncomplicated cataract surgery and its relation to the posterior vitreous traction syndrome

Setting:

S. Fyodorov Eye Microsurgery State Institution, Moscow, Russia

Methods:

32 patients (32 eyes) undergone cataract surgery. Clinical characteristics and surgical video were documented. Postoperatively, the OCT was performed with spectral domain RTVue-100 OCT (Optovue, Inc., Fremont, CA) with cornea line scan mode and vitreoretinal interface was evaluated at the retina map mode at the first week, one month,  and 6 month of follow-up(FU). The sample size would be increased by the date of the study presentation to confirm results.

Results:

Three cases were complicated by small-sized intraoperative posterior capsule (PC) rupture. In the early postoperative period the hyaloid-capsular interspace was identified in 25 cases via OCT. In all cases with PC rupture the anterior hyaloid (AH) was adhered to the IOL. At the one month postoperatively, the Berger space was identified in the 6 cases. Out of 6 cases the 4 with the present Berger space showed absence of the posterior vitreous detachment (PVD), whether the other 2 cases with no Berger space and the adherence of the PC to the IOL showed the PVD.

Conclusions:

The OCT confirms the dynamic changes of vitreolenticular interface that is more prone to be absent in the cases of PC rupture, that may confirm the positive pressure of the aqueous humor directing the PC anteriorly in postoperative period. In case of AH damage, that theory would support the migration of the vitreous composites anteriorly increasing the risk of intraocular inflammation and vitreous traction syndrome. Vitreous movement was confirmed in the small sample size, as the PVD was associated with the collapse of the vitreolenticular interspace as well as the PC movement anteriorly to the posterior surface of the IOL.
