Factors influencing retinal redetachment after removal of buckling elements
Abstract:
Scleral buckling elements were removed from 152 eyes because of infection (50 eyes), erosion (69 eyes), extrusion (25 eyes), pain (5 eyes), allergy (2 eyes), and excessive buckle height (1 eye). The overall retinal redetachment rate was 14.5%. Short duration of buckling and the presence of retinal tears, as opposed to holes, appeared to predispose to recurrence. A significantly higher redetachment rate was found when infected buckling elements were considered alone (28%). This was attributed to the short duration of buckling and the associated inflammatory reaction found in these eyes.
Insights
Scleral buckling removal was often due to erosion or infection. Infected elements significantly increased retinal redetachment risk, highlighting the importance of managing buckle complications.
Area of Science:
- Ophthalmology
- Retinal Surgery
Background:
- Scleral buckling is a common surgical procedure for retinal detachment.
- Complications can necessitate the removal of buckling elements.
Purpose of the Study:
- To analyze the reasons for scleral buckling element removal.
- To determine the impact of buckle removal and associated factors on retinal redetachment rates.
Main Methods:
- Retrospective analysis of 152 eyes undergoing scleral buckling element removal.
- Categorization of removal reasons: infection, erosion, extrusion, pain, allergy, and excessive height.
- Calculation of overall and complication-specific retinal redetachment rates.
Main Results:
- The most common reasons for removal were erosion (69 eyes) and infection (50 eyes).
- Overall redetachment rate was 14.5%.
- Infected buckle elements were associated with a significantly higher redetachment rate (28%), linked to short buckling duration and inflammation.
Conclusions:
- Erosion and infection are primary indications for scleral buckling element removal.
- Infection significantly elevates the risk of retinal redetachment post-buckle removal.
- Short buckling duration and inflammatory responses in infected cases contribute to recurrence.
