Slit-shaped artificial pupil and very dense nuclear cataract after early iridoplasty: May consultation #1
Insights
This case study discusses a 17-year-old girl with a congenital pupil defect and dense cataract. Surgical options for cataract removal and pupil reconstruction are explored to improve vision and appearance.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Congenital Eye Anomalies
Background:
- A 17-year-old female presents with a history of congenital aniridia and complicated pupilloplasty in infancy.
- Previous surgeries resulted in vitreous hemorrhage and primary persistent hyperplastic vitreous (PHPV).
Observation:
- The patient now has a slit-shaped pupil due to iris incarceration in a corneal scar.
- A dense nuclear cataract is present, significantly impacting vision.
- Intraocular pressure is normal, and the retina is attached.
Findings:
- The patient desires cataract removal for visual rehabilitation and pupil reconstruction for cosmetic improvement.
- Ocular examination reveals corneal scarring, iridocorneal synechiae, and a "cat's eye" pupil.
Implications:
- This case highlights the challenges in managing complex congenital eye conditions.
- Surgical strategies for combined cataract extraction and pupilloplasty in a scarred eye require careful consideration.
Abstract:
A now-17-year-old girl was reportedly born with no pupil formed in her right eye. In her first week of life, she underwent attempted pupilloplasty at a foreign institution. Surgery was reported to have been complicated and followed by vitreous hemorrhage. Nine months later, the eye was reevaluated at another institution and the presence of primary persistent hyperplastic vitreous noted. Secondary widening of the artificial pupil was performed. She now presents with a slit-shaped pupil and a very dense nuclear cataract (). She now desires removal of the cataract to regain the temporal visual field and at least some residual vision as well as reformation of the pupil for cosmetic reasons.(Figure is included in full-text article.)Slitlamp examination shows superficial corneal scarring around a corneal incision and corneal sutures superiorly with iridocorneal synechiae between 10 and 12 o'clock confirmed on gonioscopy. It appears that a primary inferiorly displaced pupil was enlarged, and the iris shanks pulled up and incarcerated in the corneal incision, resulting in a slit-shaped cat's eye pupil. Intraocular pressure was 10 mm Hg. Light perception is uncertain but definitely positive on transillumination, and ultrasound reveals the retina to be fully attached ().(Figure is included in full-text article.)How would you counsel this girl, and what would be your surgical approach? Which specific techniques would you consider for removal of the cataract and reformation of the pupil?
