[Development of epimacular membrane following rhegmatogenous retinal detachment surgery]
1Department of Ophthalmology, Kagoshima University Faculty of Medicine, Japan.
Abstract:
To understand the development of epimacular membrane following rhegmatogenous retinal detachment surgery, we studied 105 eyes which had undergone scleral buckling procedure. The membrane was observed in 25 eyes (24%) one month after surgery, and showed gradual increase in its occurrence up to some 50% at nine months postoperatively. Eyes without preoperative posterior vitreous detachment showed no membrane during the postoperative course. A comparison between preoperative detached macula cases with intact macula cases revealed that the occurrence of the membrane was higher in the intact macula cases, being 68% at 12 months after surgery.
Insights
Epimacular membrane development after rhegmatogenous retinal detachment surgery is common, affecting up to 50% of patients by nine months. Preoperative posterior vitreous detachment appears to prevent membrane formation.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Macular Diseases
Background:
- Epimacular membrane (EMM) formation is a known complication after retinal detachment surgery.
- Understanding the incidence and risk factors for EMM post-rhegmatogenous retinal detachment (RRD) surgery is crucial for patient management.
Purpose of the Study:
- To investigate the incidence and temporal development of epimacular membrane following scleral buckling surgery for rhegmatogenous retinal detachment.
- To identify potential predictive factors for EMM development.
Main Methods:
- A retrospective study of 105 eyes undergoing scleral buckling for RRD.
- Postoperative follow-up to assess for EMM development at one, nine, and twelve months.
- Analysis of preoperative factors including posterior vitreous detachment (PVD) and macular status.
Main Results:
- Epimacular membrane was observed in 24% of eyes at one month, increasing to 50% by nine months post-surgery.
- No EMM developed in eyes without preoperative posterior vitreous detachment.
- EMM occurred more frequently (68% at 12 months) in eyes with a preoperative intact macula compared to those with a detached macula.
Conclusions:
- Epimacular membrane is a frequent complication after scleral buckling for RRD, with incidence increasing over time.
- The absence of preoperative posterior vitreous detachment is associated with a lack of postoperative EMM.
- Intact macula preoperatively may be a risk factor for developing EMM after RRD surgery.
