1. Intraocular/vitreoretinal lymphoma and diagnostic challenges
What it is:
A rare intraocular cancer (often linked to CNS lymphoma) that can mimic uveitis.
Symptoms:
Blurred vision, floaters, mild inflammation unresponsive to treatment.
Treatment:
Challenging diagnosis (vitreous biopsy), managed with chemotherapy and/or radiotherapy.
2. Systemic and infectious diseases with ocular manifestations
What it is:
Systemic or infectious diseases that also affect the eyes.
Symptoms:
Vary widely – may include redness, pain, blurred vision.
Treatment:
Management of the underlying disease in a multidisciplinary approach.
3. Ocular manifestations of West Nile virus infection
What it is:
A viral infection that may involve the retina and optic nerve.
Symptoms:
Vision loss, floaters, visual disturbances.
Treatment:
Supportive care and management of complications.
4. Von Hippel–Lindau disease: diagnostic and therapeutic challenges
What it is:
A hereditary syndrome causing vascular tumors, including in the retina.
Symptoms:
Often asymptomatic initially; later vision loss or complications.
Treatment:
Regular monitoring and treatment (laser or surgery) depending on lesions.
5. Highly complex neuro-ophthalmologic cases
What it is:
Conditions involving the connection between the eye and the nervous system (optic nerve, brain).
Symptoms:
Double vision, vision loss, visual field defects, headaches.
Treatment:
Detailed diagnostic workup (imaging, neurological evaluation) and targeted therapy.
6. Infectious and inflammatory masquerade syndromes
What it is:
Conditions that mimic inflammatory eye diseases but have a different underlying cause (e.g. malignancies).
Symptoms:
Persistent or atypical inflammation unresponsive to treatment.
Treatment:
Specialized diagnostic testing (biopsy, labs) and targeted management.
