Isolated ectopia lentis with partial anterior dislocation and pupillary block: a case report

Area of Science:

• Ophthalmology
• Genetics
• Medical Imaging

Background:

• Ectopia lentis, or lens dislocation, typically arises from trauma or systemic conditions.
• This report details a rare instance of isolated ectopia lentis in a healthy pediatric patient.

Observation:

• A four-year-old boy presented with bilateral partial anterior lens dislocation and pupillary block.
• Smartphone images captured the dislocated lens and dilated pupil during an acute episode.
• Ophthalmic evaluation revealed decreased visual acuity, iridodenesis, and inferonasal/inferior lens subluxation.

Findings:

• Genetic testing was unremarkable, indicating an isolated presentation.
• The patient experienced sudden left eye pain, with the lens subluxing into the pupil, causing elevated intraocular pressure.
• Surgical lens removal (lensectomy) was performed, followed by aphakic correction.

Implications:

• This case underscores the diagnostic utility of patient-captured smartphone images in ophthalmic emergencies.
• Early recognition and intervention are crucial for managing lens dislocation and preventing vision loss.
• Prophylactic lensectomy in the fellow eye preserved visual acuity.
