Phenol red thread test vs Schirmer's test: a comparative study.

AIM: To measure the agreement between Schirmer's and phenol red thread tests in detecting dry eyes. PATIENTS AND METHODS: A total of 103 patients attending preoperative cataract assessment clinic who agreed to be involved in the study were recruited. Each patient had one eye examined by both tests in a random order by two different investigators who were unaware of the results of the other test. Dry eye symptoms were assessed using an interviewer-administered questionnaire. The data were collected after the study period and analysed using kappa statistics to assess the agreement between the two tests. RESULTS: Schirmer's test was positive in 25 patients when a cutoff point of 5 mm was used and positive in 41 patients with a cutoff point of 10 mm. Phenol red thread test was positive in four patients when a cutoff point of 10 mm was used and in 32 patients with a cutoff point of 20 mm. Kappa ranged from 0.067 to 0.3 indicating very weak agreement between the two tests. In all, 27% of the patients had symptoms of dry eyes; however, the agreement between each test and the symptoms was very poor. CONCLUSION: There is very weak agreement between Schirmer's test and phenol red thread tests and between each test and symptoms of dry eyes.

A comparative study of post-operative pain in laser epithelial keratomileusis versus photorefractive keratectomy.

BACKGROUND: To compare the level of post-operative pain associated with two methods of excimer laser corneal refractive surgery: PRK (photorefractive keratectomy) versus LASEK (laser epithelial keratomileusis). METHODS: 14 patients undergoing simultaneous bilateral myopic PRK were included in the study. The first eye of each patient was randomly allocated for treatment by either LASEK or PRK with alcohol-assisted epithelial debridement and second eyes were treated with the other technique. Laser corneal ablation was performed with Nidek EC-5000 excimer laser by one surgeon (MAA) using the same algorithm. Post-operatively, all patients had declofenac sodium 0.1% eye drops four times a day, lorazepam 2mg at night and two solpadol (paracetamol 500mg and codeine phosphate 30mg) tablets every six hours orally for two days. Chloramphenicol 0.5% drops four times a day were also administered for seven days. The level of pain in each eye was assessed 2, 12, 24 and 48 hours following laser surgery using a descriptive pain score from 0 to 10. Statistical analysis was performed using paired t test. RESULTS: The mean pain score at two hours post-operatively was 3.5 +/- 2.24(SD) in the LASEK group and 5.7 +/- 2.02(SD) in the PRK group. This difference is statistically significant. At 12 hours it was 4.33 +/- 2.53 (SD) and 4.75 +/- 2.30 (SD), at 24 hours it was 3.71 +/-2.84 (SD) and 4.00 +/- 2.48 (SD), and at 48 hours it was 2.86 +/- 3.43 (SD) and 2.21 +/- 2.55 (SD). There was no statistically significant difference in the pain score at these intervals. CONCLUSIONS: Post-operative pain was less in eyes treated with LASEK than eyes treated with PRK 2 hours following laser surgery. This was statisticaly significant and there was no statistically significant difference at 12, 24 and 48 hours.
