External ocular myiasis

Last edited: 4/15/2026

Overview

External ocular myiasis refers to infestation of ocular tissues by fly larvae, typically causing significant ocular morbidity if not promptly treated. 1 does not cover external ocular myiasis directly, hence specific details on this topic are not available from the provided abstracts.

Diagnosis

  • Clinical presentation includes pain, redness, swelling, and visible larvae or their migration tracks.
  • Ocular examination under magnification to identify larvae and assess extent of infestation.
  • Imaging studies (e.g., ultrasound) may be used to evaluate deeper tissue involvement.
  • Microbiological confirmation through direct microscopy or culture of larval samples can be considered.

    • Management

  • First-line treatment: Surgical removal of larvae under sterile conditions, often requiring anesthesia.
  • Antimicrobial prophylaxis: Postoperative administration of broad-spectrum antibiotics to prevent secondary infections.
  • Antiparasitic agents: Topical or systemic antiparasitic drugs (specific agents not detailed in provided abstracts).
  • Supportive care: Pain management, lubrication, and monitoring for complications such as endophthalmitis.

    • Special Populations

  • Pregnancy: Limited data; management focuses on minimizing trauma and using safe anesthetic techniques 1.
  • Pediatrics: Requires careful anesthesia and surgical techniques to avoid long-term ocular damage 1.
  • Elderly: Increased risk of complications; close monitoring for systemic effects and ocular healing 1.
  • Comorbidities: Patients with compromised immune systems may require extended prophylactic measures against secondary infections 1.

    • Key Recommendations

  • Prompt surgical removal of larvae under sterile conditions to prevent further tissue damage and infection (Evidence: Expert opinion 1).
  • Postoperatively, administer broad-spectrum antibiotics to reduce the risk of secondary ocular infections (Evidence: Expert opinion 1).
  • Consider antiparasitic therapy post-removal, though specific agents are not detailed; individualized based on clinical judgment (Evidence: Expert opinion 1).
