From the Research
ROPLAS (Rapid Ophthalmic Plastic Alignment System) cannot fully replace lacrimal syringing for diagnosing and treating nasolacrimal duct obstruction. This is based on the most recent and highest quality study available, which compared the diagnostic accuracy of ROPLAS with lacrimal irrigation in detecting nasolacrimal duct obstruction prior to cataract surgery 1. The study found that ROPLAS had a low sensitivity of 54.5% and a low positive predictive value of 75.3% in detecting nasolacrimal duct obstruction, whereas lacrimal irrigation remained the gold standard for definitive diagnosis and therapeutic intervention.
Key Points
- ROPLAS is a diagnostic tool that uses pressure applied to the lacrimal sac to assess patency of the nasolacrimal system.
- Lacrimal syringing remains the gold standard for definitive diagnosis and therapeutic intervention.
- ROPLAS offers advantages as a quick, non-invasive screening test that doesn't require irrigation fluid or risk introducing infection.
- However, it has limitations in determining the exact location of blockages and cannot clear obstructions like syringing can.
- For complete management of nasolacrimal duct obstruction, clinicians should use ROPLAS as a complementary tool alongside traditional syringing rather than as a replacement.
Clinical Implications
The diagnostic accuracy of ROPLAS is improved when combined with other clinical assessments, including the dye disappearance test and lacrimal syringing when necessary for definitive diagnosis and treatment 1. Therefore, clinicians should use ROPLAS as a complementary tool alongside traditional syringing rather than as a replacement. This approach ensures that patients receive accurate diagnoses and effective treatment for nasolacrimal duct obstruction, ultimately improving their quality of life and reducing the risk of complications.
Supporting Evidence
Other studies have also highlighted the importance of lacrimal syringing in diagnosing and treating nasolacrimal duct obstruction 2, 3, 4, 5. While these studies provide valuable insights into the diagnosis and treatment of nasolacrimal duct obstruction, the most recent and highest quality study 1 provides the strongest evidence for the use of ROPLAS as a complementary tool alongside traditional syringing.
