Summary
Most primary care physicians do not routinely screen for glaucoma due to lack of equipment and skills. Improved training and access to resources are crucial for enhancing glaucoma screening in primary care.
Area of Science:
- Ophthalmology
- Primary Care Medicine
- Public Health
Background:
- Glaucoma is a leading cause of irreversible blindness.
- Early detection through screening is vital for preventing vision loss.
- Primary care physicians (PCPs) play a potential role in glaucoma risk assessment.
Purpose of the Study:
- To determine the proportion of PCPs who routinely assess glaucoma risk factors.
- To identify factors influencing glaucoma screening practices among PCPs.
Main Methods:
- A confidential questionnaire was distributed to PCPs on three separate occasions.
- The survey collected data on physician background, screening habits, and barriers to screening.
- Responses were categorized, and percentages were calculated.
Main Results:
- A 30.4% response rate (49/161) was achieved.
- 53% of responding PCPs reported routine glaucoma screening; urban physicians screened more than rural physicians (57% vs. 44%).
- Lack of equipment (48%) and skills (30%) were primary reasons for not screening; 85% would refer suspected cases. Training and equipment access were identified as key facilitators for screening.
Conclusions:
- PCPs' involvement in glaucoma screening requires further evaluation.
- Education and improved access to equipment are critical for increasing PCP glaucoma screening.
- Addressing barriers like equipment and training is essential for effective public health initiatives targeting glaucoma.
