Tamponade Agent Selection in Rhegmatogenous Retinal Detachment Treatment


ABSTRACT

Aim:

Optimization of the indications for use of various tamponade agents during surgical treatment of recurrences of retinal detachment, taking into account some social and technical factors.

Materials & Methods:

Anatomical and functional results of the treatment of retinal detachment recurrences were analyzed. Vitreous cavity revision with lower releasing retinotomy 180o were performed. 30 patients (30 eyes) were operated on with silicone oil retamponade. 30 patients (30 eyes) were operated on with non-expanding C3F8 gas-air mixture retamponade. During the primary intervention silicone oil tamponade was applied in all 60 patients.

Results:

After interventions with silicone oil retamponade retinal reattachment was achieved in 90.0 ± 3.8% of cases, and in patients with gas retamponade in 93.3 ± 3.3% of cases (p≥0,01). Visual acuity after the final silicone oil removal and gas resorption ranged from 0.1 to 0.6, on average 0,36 ± 0,04 and 0,41 ± 0,05 respectively (p≥0,01). No significant difference in retina reattachment rate and its functional state between cases with silicone oil retamponade and gas retamponade was found. This causes expediency of gas use in surgical interventions for retinal detachment recurrences, as it reduces the concentration of proliferative factors in aqueous humor, tamponade agent removal is not needed, reduces the cost price of surgery.

Conclusion:

Obtained data support the use of non-expanding gas-air mixture of C3F8 during interventions for retinal detachment recurrences. This justifies the use of silicone oil tamponade in primary interventions as a method that allows the patient to see next morning. And the use of gas tamponade in the subsequent interventions for retinal detachment recurrences, as a method which benefits are: decrement of proliferative factors concentration in aqueous humor, tamponade agent removal is not needed, lower cost of consumables.
