Insights

Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) can be linked to systemic infections. A case study shows APMPPE occurring with acute nephritis, suggesting a potential link to general vasculitis.

Area of Science:

  • Ophthalmology
  • Nephrology
  • Rheumatology

Background:

  • A potential association between acute posterior multifocal placoid pigment epitheliopathy (APMPPE) and systemic infections has been previously hypothesized.
  • This case report details an instance of APMPPE occurring concurrently with acute nephritis in an otherwise healthy male patient.

Observation:

  • The patient presented with systemic symptoms including arthralgia, headache, fever, malaise, and lymphadenopathy.
  • Within two weeks, symptoms of mild nephritis emerged, alongside a sudden and significant decrease in visual acuity to 0.08 (20/250) in both eyes.
  • Ophthalmic examination revealed mild anterior uveitis and characteristic pigment epithelial swelling in the posterior pole, consistent with APMPPE.

Findings:

  • The fundus lesions associated with APMPPE showed healing over a four-week period, resulting in residual pigment epithelial atrophy and macular pigment dispersion.
  • Visual acuity improved significantly to 0.8 (20/25) in the right eye and 1.0 (20/20) in the left eye post-healing.
  • No specific systemic therapy was administered during the observation period.

Implications:

  • This case provides further evidence supporting the theory that APMPPE may be caused by a generalized vasculitic process.
  • The co-occurrence of APMPPE and acute nephritis highlights the potential systemic nature of conditions affecting the retinal pigment epithelium.
  • Further research into the link between infectious agents, vasculitis, and APMPPE is warranted.
