Summary
Buckle size impacts eye muscle function after retinal detachment surgery. Smaller buckles (≤4 mm) are recommended to minimize motility disturbances and diplopia, improving patient outcomes.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Oculomotor Function
Context:
- Episcleral buckle surgery for retinal detachment can cause motility disturbances.
- Previous reports show a wide incidence range (7-77%) of these disturbances.
Purpose:
- To investigate the relationship between episcleral buckle size and the incidence/extent of motility disturbances.
- To assess the impact of buckle size on diplopia, heterophoria, and stereopsis post-retinal detachment surgery.
Summary:
- A study of 45 patients 2-4 years post-retinal detachment surgery found hypermotility in 22/45 cases and hypomotility in 1/45.
- Diplopia was reported by 7/32 patients with buckles ≥5 mm, but by none with buckles ≤4 mm.
- Stereopsis was preserved in most patients, regardless of macular involvement.
Impact:
- Findings suggest that larger buckles (≥5 mm) are associated with increased motility disturbances and diplopia.
- Recommends using smaller buckles (≤4 mm) when feasible to reduce the risk of ocular motility complications.
- Highlights the importance of buckle size selection for optimizing functional outcomes after retinal detachment repair.
