Two patients developed full-thickness macular holes after panretinal photocoagulation for proliferative diabetic retinopathy. Surgical repair with vitrectomy was successful for both cases, though the link to the initial treatment remains unclear.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Diabetic Retinopathy
Background:
- Panretinal photocoagulation (PRP) is a standard treatment for proliferative diabetic retinopathy (PDR).
- Macular holes can be a complication of various retinal conditions and treatments.
Observation:
- Two patients with PDR and epiretinal membranes developed full-thickness macular holes post-PRP.
- Optical coherence tomography revealed foveal thinning and lamellar holes preceding full-thickness macular hole formation.
Findings:
- Full-thickness macular holes developed in both patients within six months of PRP.
- Both patients achieved successful visual recovery after surgical intervention including vitrectomy and membrane peeling.
Implications:
- This case series highlights a potential, though unclear, association between PRP and macular hole development in PDR patients.
- Further investigation is warranted to understand the underlying mechanisms and clinical significance of this observation.
