Abstract:
We review 12 consecutive cases of pre-macular fibrosis (PMF) treated by vitreous surgical techniques. The causes of PMF included retinal detachment surgery in four patients, idiopathic in three patients, laser treatment in three patients, pars planitis in one patient and diabetic retinopathy in one patient. The membrane was successfully removed in all the patients. One patient developed a retinal detachment that was repaired successfully. All patients had improved visual acuity (VA) of two Snellen lines or more and six patients achieved VA of 6/12 or better. Patients with PMF following retinal detachment had poorer final VA.
Insights
Vitreous surgery effectively removed pre-macular fibrosis (PMF) in 12 patients, improving visual acuity (VA). While generally successful, PMF after retinal detachment surgery led to poorer outcomes.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Vitreoretinal Diseases
Background:
- Pre-macular fibrosis (PMF) is a condition affecting vision.
- Surgical intervention is considered for PMF.
- Understanding outcomes of surgical treatment is important.
Purpose of the Study:
- To evaluate the efficacy of vitreous surgical techniques for treating pre-macular fibrosis (PMF).
- To assess visual acuity outcomes in patients undergoing PMF surgery.
Main Methods:
- Retrospective review of 12 consecutive cases of pre-macular fibrosis (PMF).
- All patients were treated with vitreous surgical techniques.
- Data collected included causes of PMF, surgical outcomes, and visual acuity (VA).
Main Results:
- The pre-macular membrane was successfully removed in all 12 patients.
- All patients experienced improved visual acuity (VA) of at least two Snellen lines.
- Six patients achieved a final VA of 6/12 or better.
- One patient experienced a retinal detachment post-surgery, which was successfully repaired.
- Patients with PMF secondary to retinal detachment surgery had poorer final VA.
Conclusions:
- Vitreous surgical techniques are effective in removing pre-macular fibrosis (PMF) and improving visual acuity (VA).
- While surgical outcomes are generally favorable, pre-macular fibrosis following retinal detachment surgery may result in less optimal visual outcomes.
