Abstract Details

Purpose:

To evaluate the anatomical and functional results of pars plana vitrectomy (PPV) in eyes with osteo-keratoprosthesis (OKP), who have suffered retinal detachment (RD).

Setting:

Centro de OftalmologĂ­a Barraquer

Methods:

An observational, retrospective study of eyes which underwent PPV for RD after an implantation of an OKP. Eighteen eyes of seventeen patients that underwent vitreoretinal surgery between 1999 and 2014 at the Centro de OftalmologĂ­a Barraquer were included. The minimum follow-up after RD surgery was 1 year. Demographic characteristics, primary corneal pathology and complications were collected. A Kaplan-Meier survival analysis for anatomical and functional success was performed. Anatomical success was defined as an attached retina at the end of vitreoretinal surgery with no re-detachment during the follow-up. Functional success was defined as a postoperative VA of more than or equal to 0.05 on the decimal scale.

Results:

Original diagnosis of the corneal pathology was chemical injury in 6 eyes (33%), autoimmune disease in 4 (22%), thermal burn in 3 (17%), and 5 eyes (28%) had other different diagnoses. The overall rate of anatomical success was 56% and the overall cumulative anatomical success rates by Kaplan-Meier survival analysis were 67% and 53% at 6 and 12 months respectively, maintaining this last value at 24 months after PPV. The overall rate of functional success was 17% and the overall cumulative functional success rates were 83%, 39% and 14% at 6, 12 and 24 months after PPV, respectively. The most frequent complication after retinal surgery was retroprosthetic membrane (33%).

Conclusions:

Despite the reserved prognostic and the severe complications, vitrectomy represents a valid method for treating RD in patients with OKP, with good anatomical results but poor visual acuity, both in the medium and long term.
