Summary
Microbiological studies are crucial for diagnosing acute conjunctivitis. This study found bacterial infections in 32 cases, fungal infections in 14, and mixed infections in 30, highlighting the need for accurate etiological diagnosis.
Area of Science:
- Ophthalmology
- Microbiology
Background:
- Acute conjunctivitis is a common ocular condition with diverse causes.
- Accurate etiological diagnosis is vital for effective treatment and preventing complications.
Purpose of the Study:
- To investigate the microbiological and etiological profile of clinically diagnosed acute conjunctivitis.
- To determine the prevalence of bacterial, fungal, and allergic causes in acute conjunctivitis cases.
Main Methods:
- Collected samples from 102 clinically diagnosed acute conjunctivitis patients.
- Performed conventional bacterial and fungal culture studies.
- Utilized Giemsa staining to identify eosinophils for allergic etiology assessment.
Main Results:
- Bacterial infection identified in 32 cases (31.4%).
- Fungal isolation confirmed in 14 cases (13.7%).
- Allergic etiology detected in 1 case (1.0%).
- Mixed infections were present in 30 cases (29.4%).
- 25 samples (24.5%) were sterile on conventional culture.
Conclusions:
- Microbiological investigations are essential for confirming clinical diagnoses of acute conjunctivitis.
- Identifying specific pathogens or allergens guides appropriate therapeutic interventions.
- A significant proportion of acute conjunctivitis cases involve mixed infections or are culture-negative, necessitating comprehensive diagnostic approaches.
