[Surgical prognosis in idiopathic vitreomacular syndrome and epimacular membrane]

Introduction:
The natural history shows less progression for epimacular membrane than for vitreomacular traction syndrome. We tested the hypothesis that the surgical prognosis in idiopathic cases is also better for epimacular membrane.
Methods:
This retrospective study investigated a consecutive series of 63 epimacular membrane cases (group I) and 25 vitreomacular traction syndrome cases (group II) that were operated on and followed up for a minimum of 6 months. Eyes that had undergone previous surgery or had posterior or peripheral retinal lesions were excluded. In bilateral macular surgery cases, only the first eye was included. The outcome measures were far and near visual acuities preoperatively and 6 months after surgery, taking into account the crystalline lens condition, the incidence of retinal tears, detachments, and epimacular membrane recurrences.
Results:
At 6 months, if the lens was stable or operated on, the visual acuity showed at least a two-line improvement in 100% of the cases (12/12) in group I, and 60% (3/5) in group II. The incidence of retinal detachment and tears was 1.5% (1) and 1.5% (1), respectively, in group I, and 8% (2) and 4% (1), respectively, in group II. Recurrence of an epimacular membrane was observed in 6% of the cases (4) in group I and 8% (2) in group II.
Discussion And Conclusion:
In idiopathic cases, the absence of preoperative vitreomacular adhesion seems to carry a better surgical prognosis for epimacular membrane than vitreomacular traction syndrome.
Insights
Epimacular membrane surgery offers better visual acuity outcomes and lower complication rates compared to vitreomacular traction syndrome surgery. Absence of vitreomacular adhesion indicates a superior surgical prognosis.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Macular Diseases
Background:
- Epimacular membrane (EMM) typically shows slower progression than vitreomacular traction syndrome (VMTS).
- Previous research suggests differing natural histories for EMM and VMTS.
- This study investigates if surgical outcomes also differ between these conditions.
Purpose of the Study:
- To compare the surgical prognosis of epimacular membrane (EMM) versus vitreomacular traction syndrome (VMTS) in idiopathic cases.
- To evaluate visual acuity outcomes and complication rates following surgery for EMM and VMTS.
- To determine if preoperative vitreomacular adhesion influences surgical success.
Main Methods:
- Retrospective analysis of 63 EMM (group I) and 25 VMTS (group II) cases undergoing surgery.
- Minimum 6-month follow-up, excluding eyes with prior surgery or peripheral retinal lesions.
- Outcome measures included visual acuity, lens status, retinal tears/detachments, and EMM recurrence.
Main Results:
- 100% of EMM cases (lens stable/operated) achieved ≥2 line visual acuity improvement vs. 60% for VMTS.
- Lower incidence of retinal detachment (1.5% vs. 8%) and tears (1.5% vs. 4%) in EMM group.
- EMM recurrence rates were similar: 6% for EMM vs. 8% for VMTS.
Conclusions:
- Absence of preoperative vitreomacular adhesion is associated with better surgical outcomes for EMM compared to VMTS.
- EMM surgery demonstrates a more favorable prognosis regarding visual recovery and complications.
- These findings support distinct surgical management considerations for EMM and VMTS.
