Primary intraocular lymphoma (PIOL) is a rare but increasing malignancy affecting the eye. Diagnosis requires advanced techniques, and treatment involves chemotherapy and radiation.

Area of Science:

  • Ophthalmology
  • Oncology
  • Neurology

Background:

  • Intraocular lymphoma presents as primary CNS lymphoma or metastatic disease.
  • Primary intraocular lymphoma (PIOL) arises from primary CNS lymphoma involving the retina.
  • PIOL incidence has significantly increased over the last 15 years.

Purpose of the Study:

  • To differentiate primary intraocular lymphoma (PIOL) from metastatic intraocular lymphoma.
  • To outline the diagnostic challenges and methods for PIOL.
  • To describe current treatment strategies for PIOL.

Main Methods:

  • Review of clinical manifestations including blurred vision and floaters.
  • Ophthalmic examination findings such as vitreitis and subretinal infiltrates.

  • Diagnostic adjuncts including neuroimaging, cerebrospinal fluid/vitreous analysis, molecular analysis (immunoglobulin gene rearrangements), and cytokine levels (IL-10/IL-6 ratio > 1.0).

    • Main Results:

    • PIOL presents with vitreitis and subretinal infiltrates, often with diagnostic challenges.
    • Molecular and cytokine analyses aid in PIOL diagnosis.
    • Metastatic systemic lymphoma typically affects the uvea/choroid, has lower prevalence, and a better prognosis than PIOL.

    Conclusions:

    • PIOL diagnosis is complex, requiring a combination of clinical, imaging, and molecular methods.
    • Current treatment for PIOL emphasizes systemic chemotherapy followed by radiation.
    • Distinguishing PIOL from metastatic lymphoma is crucial due to differences in prognosis and management.
