Purpose: : To determine the diagnostic accuracy of manual regurgitation on pressure over the lacrimal sac (ROPLAS) versus lacrimal irrigation for screening nasolacrimal duct obstruction (NLDO) in adults prior to intraocular surgeries.Methods: This cross-sectional study took place in a tertiary eye care hospital in South Tamil Nadu, India. From January to December 2017 and included consecutive patients who presented for routine cataract surgery. Prospective data collection occurred in 8369 eyes of patients who underwent cataract surgery. All patients underwent ROPLAS testing by an ophthalmologist followed by lacrimal irrigation by trained ophthalmic assistants, rechecked or confirmed in equivocal cases by ophthalmologists who were masked to the ROPLAS status. The primary outcome, the sensitivity, specificity, positive, and negative predictive values to detect lacrimal occlusion by ROPLAS compared with lacrimal irrigation with 95% confidence intervals was estimated.Results: : A total of 8369 eyes underwent cataract surgery during the time periods of the study. ROPLAS and lacrimal irrigation were performed in all eyes. The sensitivity of ROPLAS to diagnose NLDO correctly was 54.5% (95% CI, 44.8%-63.9%) and its specificity was 100% (95% CI, 100%-100%). The positive and negative predictive values were 75.3% (95% CI, 65.6%-83.0%) and 99.4% (95% CI, 99.2%-99.5%), respectively.Conclusion: : We found that ROPLAS when used alone had very low sensitivity and low positive predictive value in detecting NLDO prior to cataract surgery as compared with lacrimal irrigation. Hence, we recommend performing ROPLAS and lacrimal irrigation in every patient as part of the routine preoperative workup prior to cataract surgery. [ABSTRACT FROM AUTHOR]

This study was designed and intended to reveal the etiology of epiphora or Watery eyes referrals to ophthalmology department in Baquba teaching hospital. Cross-sectional study we blindly select 200 patients complaining of epiphora Baquba teaching hospital. Data collection was done in the ophthalmology department in outpatient clinic of the hospital. Patient demographics, past history and ophthalmic examination has been done for the selected subjects. There were 200 subjects with a primary complaint of epiphora. They included (55%) females and (45%) males with an average age of 56.9±23.9y. The most common causes of epiphora were lacrimal obstruction (50%); followed by reflex tearing (36%) and eyelid malposition (14%). Differences in prevalence of aetiology were noted in the terms of age and gender distribution. In conclusion, epiphora is a common condition generally affecting babies and older people with many etiology. A thorough history and examination are required to provide the appropriate treatment to the underlying cause. [ABSTRACT FROM AUTHOR]

This analysis is based on the study of Russian and foreign literature sources devoted to both high-tech and routine methods of studying the lacrimal drainage system, as well as the description of modern methods of conservative and surgical treatment of lacrimal stenosis. This article gives information about advantages and disadvantages of each of the methods of diagnosis and treatment of obliteration of the lacrimal tract, highlights the questions of their usage in dacryology.
