A case of angle-closure glaucoma caused by spontaneous lens dislocation

Area of Science:

• Ophthalmology
• Radiology
• Medical Diagnostics

Background:

• Spontaneous lens dislocation is uncommon, particularly when not linked to genetic predispositions.
• Secondary angle-closure glaucoma can arise as a complication of lens displacement.

Observation:

• A case of spontaneous lens dislocation occurred without any identifiable precipitating factor.
• The patient presented with symptoms necessitating a head computed tomography (CT) scan.

Findings:

• The head CT scan definitively identified the presence of lens dislocation.
• The dislocation was spontaneous, occurring without a clear trigger or known genetic link.

Implications:

• This case highlights the importance of considering lens dislocation in the differential diagnosis of sudden headaches.
• Radiologists and clinicians should be vigilant in assessing for lens dislocation on head CT scans, even in the absence of typical risk factors.
