Pseudophaco--anaphylactic endophthalmitis? P.M.M.A. related
Acta Ophthalmologica. Supplement
|January 1, 1985
Summary
Pseudophacoanaphylactic endophthalmitis occurred in a patient with combined eye surgery and injury. The reaction was linked to the polymethylmethacrylate (P.M.M.A.) lens optic, not the polypropylene loops.
Area of Science:
- Ophthalmology
- Pathology
- Ophthalmic Surgery
Background:
- A patient underwent combined trabeculectomy, extracapsular cataract extraction, and posterior chamber lens implantation.
- The patient sustained a perforating eye injury shortly after the operation, leading to sympathetic ophthalmitis.
Observation:
- Histological examination revealed typical sympathetic ophthalmitis findings.
- A distinct pseudophacoanaphylactic endophthalmitis reaction was observed in the affected eye.
Findings:
- The pseudophacoanaphylactic reaction was strongly associated with the polymethylmethacrylate (P.M.M.A.) optic of the intraocular lens.
- The polypropylene loops of the "in-the-bag" lens showed no significant histological inflammatory response.
Implications:
- This case highlights a specific inflammatory reaction to P.M.M.A. intraocular lens material in the context of combined ocular surgery and injury.
- Understanding these pathological responses is crucial for evaluating intraocular lens materials and managing complex ophthalmic cases.

Naturalistic Observations
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
Cognitive Development During Adulthood
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...
