title: After-cataract and secondary glaucoma in the aphakic infant rabbit.
abstract: OBJECTIVE
  To study the association between after-cataract and secondary glaucoma after lensectomy and 5-fluorouracil treatment in an experimental infant rabbit model.
  
  
  METHODS
  St Erik Eye Hospital, Karolinska Institute, Stockholm, Sweden.
  
  
  METHODS
  Lensectomy was performed in both eyes of 16 3-week-old rabbits. One randomly selected eye in each rabbit was injected with 2.5 mg of 5-fluorouracil (5-FU) at surgery and 5.0 mg the day after surgery to reduce the formation of after-cataract. Axial length, corneal thickness, corneal diameter, and intraocular pressure were measured preoperatively and 4 times during the 6 months following surgery. Six months after surgery, the wet weight of the after-cataract was determined.
  
  
  RESULTS
  In 16 aphakic eyes treated with 5-FU, no or a minimal amount (<0.001 g) of after-cataract developed. None of the eyes showed signs of secondary glaucoma. Of 16 aphakic eyes not treated with 5-FU, 10 developed considerable amounts of after-cataract (>0.10 g); 8 of these developed glaucoma. The other 6 eyes had no or minimal after-cataract and did not develop secondary glaucoma. The relationship between after-cataract and secondary glaucoma was statistically significant.
  
  
  CONCLUSIONS
  A significant relationship between the amount of after-cataract and the development of secondary glaucoma was found in aphakic infant rabbit eyes.
