Lunar lenses - Acquired lens colobomas

Area of Science:

• Ophthalmology
• Pediatric Surgery
• Ocular Pathology

Background:

• Acquired lens colobomas are infrequently documented, particularly in pediatric populations.
• Lens colobomas can arise secondary to various ocular surgical interventions.
• Understanding these complications is crucial for managing pediatric glaucoma and retinal detachment.

Purpose of the Study:

• To report and analyze two cases of acquired lens coloboma in infants following ocular surgery.
• To investigate the potential mechanisms leading to acquired lens coloboma in the context of pediatric glaucoma and retinal detachment surgery.

Main Methods:

• Case report detailing clinical presentation and surgical history.
• Review of intraoperative events and postoperative findings.
• Pathophysiological analysis of potential zonular damage during specific surgical procedures.

Main Results:

• Two infants with glaucoma developed acquired lens colobomas post-surgery.
• Case 1: Suspected direct zonular trauma during optical iridectomy and vitrectomy.
• Case 2: Possible zonular disruption from globe stretching or surgical injury during scleral buckling and cryopexy.

Conclusions:

• Acquired lens colobomas can occur as a rare complication of pediatric ocular surgery.
• Surgical manipulation, including vitrectomy, iridectomy, scleral buckling, and cryopexy, may lead to zonular damage and subsequent lens coloboma.
• Further investigation is warranted to fully elucidate the incidence and causative factors of acquired lens colobomas in pediatric surgery.
