Abstract:
Epimacular membranes /EMM/ reduce markedly visual acuity and the only treatment is pars plana vitrectomy /PPV/ and removal of the EMM. The authors analyzed the results of PPV in 30 eyes with EMM of different aetiology. The group comprised 4 idiopathic EMM and 26 secondary EMM after operations of a detached retina, injury, intraocular inflammation, occlusion of the retinal vein and retinopathies of the premature. The operation markedly improved the visual acuity in 20 eyes /67%/ and the best results were obtained in idiopathic EMM. The prognosis did not depend on the preoperative visual acuity and duration of the disease and was determined by the state of the macula beneath EMM which in dense secondary EMM is difficult to assess before operation. The poorest functional results were obtained in postinflammatory and post-traumatic EMM.
Insights
Pars plana vitrectomy (PPV) effectively treats epimacular membranes (EMM), significantly improving vision in 67% of cases. Best outcomes were seen in idiopathic EMM, while post-inflammatory and post-traumatic cases showed poorer results.
Area of Science:
- Ophthalmology
- Retinal Surgery
Context:
- Epimacular membranes (EMM) significantly impair visual acuity.
- Pars plana vitrectomy (PPV) is the primary surgical intervention for EMM removal.
Purpose:
- To evaluate the outcomes of PPV in patients with EMM of various etiologies.
- To identify factors influencing visual acuity improvement after EMM removal.
Summary:
- The study analyzed 30 eyes undergoing PPV for EMM.
- Idiopathic EMM showed the best visual acuity improvement (67% success rate).
- Secondary EMM, particularly post-inflammatory and post-traumatic, had poorer functional results.
Impact:
- PPV is a successful treatment for EMM, with outcomes depending on the underlying cause and macular status.
- Preoperative assessment of the macula beneath dense EMM is crucial for prognosis.
