Long-term myofibroblast persistence in the capsular bag contributes to the late spontaneous in-the-bag intraocular lens dislocation.

Late spontaneous in-the-bag intraocular lens (IOL) dislocation is a complication presenting 6 months or later after cataract surgery. We aimed to characterize the cells in the lens capsules (LCs) of 18 patients with spontaneous late in-the-bag IOL dislocation. Patients' average age was 82.

[Two-port pars plana vitreomacular surgery without endoillumination].

Purpose: To present a two-port endovitreal surgery technique without endoillumination as a method of choice for sparing surgery of the macular area.

Material And Methods: Study group included 16 patients (16 eyes) with cataract and macular pathology (8 - with a macular hole (MH) and 8 - with epiretinal fibrosis). Preoperative mean best corrected visual acuity (BCVA) was 0.

[Functional outcomes of idiopathic macular hole surgeries].

Aim: To study the dynamics of visual status and its correlation with morphological changes in patients operated for idiopathic macular hole (IMH).

Material And Methods: The study enrolled 78 patients (82 eyes) whose ocular media remained transparent throughout the whole follow-up period that started 1 month after a successful IMH surgery and lasted for no less than a year. Two equivalent subgroups, 29 patients (30 eyes) each, were then formed and designated as «transparent media» (pseudophakic patients or those who remained free of cataract over the follow-up period) and «comparison».

Predicting anatomical results of surgical treatment of idiopathic macular hole.

Aim: To determine the parameters most informative in predicting the anatomical results of surgical treatment of idiopathic full-thickness macular hole (IMH).

Methods: One hundred and sixty-two consecutive patients (170 eyes) after primary operation for IMH were enrolled. Outcomes were classified as anatomical success when both IMH closure and restoration of the outer retinal structure were achieved.

[Induction of posterior detachment of the vitreous body by intraoperative vitreo-syneresis with injection of water-soluble polymers (an experimental-morphological study)].

The capacity of water-soluble polymers (polyethylenimine, polyvinylpyrrolidone with copolymers) to induce posterior detachment of the vitreous by its rapid condensation (vitreosynerysis) was studied in experiments on 14 rabbits. Histological studies showed that water-soluble polymers specifically react forming complexes with components of the vitreous. The vitreous shrinks under the effect of polyelectrolytes (vitreosynerysis), which leads to its posterior detachment 1.
