Abstract
Purpose: :
To evaluate the success and complication rate of the use of Oxane HD in treating complex retinal detachments.
Methods: :
We evaluated 8 consecutive eyes treated surgically with Oxane HD (Bausch and Lomb, Toulouse, France: mixture of 5700 silicone oil and RMN-3-(fluorinated/hydrocarboned olefin) for retinal detachments with complex pathologies. All cases were operated by the authors at Department of Ophthalmology, Flinders Medical Center, Bedford park, South Australia. The use of Oxane HD was selected if the retinal detachment was associated with proliferative vitreo-retinopathy, posterior inferior breaks, retinectomy and inability of patients to posture. The patients were followed at regular visits till the heavy oil was explanted. We evaluated the anatomical success rate at the final visit, and the associated complications.
Results: :
Six out of 8 eyes (75%) were aphakic and of the remaining 2, one was phakic and another pseudophakic (12.5%). 3 (37.5%) cases had PVR, 3 (37.5%) had RD associated with trauma (PEI OTS Grade III). 2 cases (25%) had posterior inferior break and 2 (25%) underwent retinectomy during the surgical procedure. The heavy oil remained in the eye from 6 weeks to 27 months. Anatomical success was achieved in 6 out of 8 eyes (75%). 4 out of 8 eyes had raised IOP which was controlled by topical medication. 3 eyes developed an ERM and another 3 developed sub-retinal membrane. 37.5% (3/8) eyes developed band keratopathy.
Conclusions: :
Oxane HD is an effective medium term tamponade for use in complex retinal detachments. It is relatively easy to handle with a low long term morbidity.
