Abstract

PURPOSE: This study analyzes the factors influencing anatomical failure of the primary operation for simple rhegmatogenous retinal detachment.
METHODS
The patients in this study were diagnosed with simple rhegmatogenous retinal detachment and operated on by a single physician. The success group comprised 251 eyes and the failure group comprised 29 eyes. The factors analyzed between the two groups were the type of primary procedure, the type of retinal defect; the numbers of retinal defects; the extent of retinal detachment; the duration of retinal detachment; the existence of peripheral degeneration; carrying out of subretinal fluid drainage; the type of tamponade material used and the position of retinal defects.
RESULTS
The anatomical success rate of the primary operation for simple rhegmatogenous retinal detachment was 89.64%. Patient sex, the type of tamponade material used and the position of the retinal defect showed significant differences between the success and failure groups. There was a higher percentage of male patients in the failure group than in success group (p=0.034). Silicone oil used as the tamponade material resulted in a greater chance of failure than success (p=0.017). Analysis of the position of the retinal defect showed that, defects distributed in the inferior retina or through multiple area led to a greater likelihood of anatomical failure (p=0.036).
CONCLUSIONS
Due ti the greater possibility of anatomical failure of the primary operation when retinal defects are distributed in the inferior retina or through multiple area, clinicians should consider intensive treatment for such cases.
