Abstract
Purpose: :
To analyze long-term anatomical results, functional outcome and complications in eyes treated with Densiron tamponade during primary surgery.
Methods: :
Densiron was applied in 26 eyes (26 patients, 16 male, median age 61.5, range 13-91 years). Eyes were presenting PVR stage A in 2, B in 6, C1-C3 in 17 cases, and stage D1 in 1 case. 22 of 26 eyes presented a macula-off detachment; 6 of these a partial foveal detachment. None of the eyes received additional buckling during primary surgery. Densiron was removed after a median of 62 days (range 17 to 99). 23 of 26 eyes were supplied with a mildly impressing encircling band at the time of Densiron removal. Mean follow-up was 15.1+/-12.1 months (median 11.3, range 3-43).
Results: :
Complete primary retinal attachment was achieved in 26/26 eyes. 1 of 26 eyes developed PVR and secondary detachment before removal of Densiron. 3 of 26 eyes developed a redetachment centrally to the encircling band repaired by secondary intervention. At the end of the follow-up all eyes presented with attached retina; in 3 of these a limited retinal detachment anterior to cerclage was observed. LogMar visual acuity improved from a preoperative level of 1.2+/-0.96 (median 0.8) to 0.79+/-0.49 (median 0.72) at 3 months, 0.64+/-0.38 (median 0.64) at 6 months and 0.44+/-0.34 (median 0.3) at 12 months. 16 of 17 phakic eyes developed a secondary cataract (15 of 16 posterior subcapsular) during follow-up. Dispersed Densiron occurred in 10 of 26 eyes in the anterior segment, 1 case presented a gross inverse pseudohypopyon. The majority of eyes (19 of 26) needed local antiglaucomatous medication during or after the period of internal tamponde; 6 of these until the end of the follow-up period. Chronic hypotony occurred in none of the eyes.
Conclusions: :
Results of this study indicate that Densiron 68® is an effective and safe heavy internal tamponade substance yielding functionally favourable results when applied in primary retinal detachment surgery with inferior retinal defects and PVR.
