Abstract:
The formation of retinal membranes can occur due to a variety of reasons but they are most commonly idiopathic due to the aging process. In addition, epiretinal and subretinal membranes can be formed after severe infections. The present case description shows the appearance of a retinal membrane after hemolytic uremic syndrome caused by Shiga toxin positive E. coli. The question arose whether the patient would benefit from vitrectomy with membrane peeling because of the presence of both epiretinal and subretinal gliotic changes. After the operation on the more severely affected right eye a morphological improvement could be achieved so that an operation on the left eye was also recommended. Judging by the course of this case vitrectomy with membrane peeling seems to be a useful instrument even for the simultaneous presence of subretinal and epiretinal membranes.
Insights
Retinal membranes, often idiopathic, can form after infections. Vitrectomy with membrane peeling successfully treated both epiretinal and subretinal membranes following hemolytic uremic syndrome, improving vision.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Surgical Interventions
Background:
- Retinal membranes, including epiretinal and subretinal types, can arise from various causes, commonly idiopathic aging or severe infections.
- Hemolytic uremic syndrome (HUS) due to Shiga toxin-producing E. coli is a rare but potential cause of retinal membrane formation.
Observation:
- A case study details a patient who developed retinal membranes after HUS.
- The patient presented with both epiretinal and subretinal gliotic changes, raising the question of surgical intervention.
Findings:
- Vitrectomy with membrane peeling was performed on the more severely affected right eye.
- Significant morphological improvement was observed post-surgery in the right eye, leading to a recommendation for operating on the left eye.
Implications:
- This case suggests that vitrectomy with membrane peeling is a viable treatment option for simultaneous epiretinal and subretinal membranes.
- The findings support the use of this surgical technique even in complex cases secondary to infections like HUS.
