purpose : to assess the results of 1-minute and 5-minute schirmer's test (st) when the eyes are open (sto) and closed (stc) in normal participants. methods : in a comparative, observational case series study, 34 normal volunteers were included in the study. inclusion criteria were normal ophthalmologic findings except for refractive errors, no use of contact lenses, no history of previous ...

PURPOSE We aimed to evaluate the feasibility of using a modified Schirmer test to determine the increase in tear volume after administration of 3% diquafosol ophthalmic solution (diquafosol 3%) in dry eye patients. PATIENTS AND METHODS A randomized, multicenter, prospective, double-blind clinical study recruited 50 qualified subjects. They received diquafosol 3% in one eye and artificial tear...

PURPOSE To define a combination of the Schirmer I and phenol red thread (PRT) tests that improves the screening of patients with ocular sicca syndrome. METHODS The PRT test was performed before (PRT1) and after (PRT2) the Schirmer I test, in both eyes of 143 patients complaining of ocular dryness secondary to Sjögren's syndrome or sicca asthenia polyalgia syndrome (SAPS; 72 and 71 patients, r...

purpose: to evaluate changes in tear condition following unilateral ptosis surgery. methods: in this case series all patients with unilateral ptosis who underwent ptosis surgery over a two-year period were studied. the patients did not have history of previous eye surgery or other eye problems. eyelid and lacrimal evaluation included schirmer’s test with and without anesthesia and tear break up...

PURPOSE To compare dry eye signs and symptoms between patients with preoperative low and normal Schirmer test after Photorefractive keratectomy (PRK). METHODS In this prospective, nonrandomized, comparative case series, 76 eyes of 76 patients were preoperatively categorized into two groups according to selected criteria for characterization of tear film status: the low Schirmer test value (ST...

BACKGROUND Dry eye is the most common ocular morbidity found in elderly patients. There is no gold standard/standard test for diagnosing dry eye. OBJECTIVES The present study was conducted to compare the potential of Phenol Red Thread (PRT) test versus Schirmer Test in diagnosing dry eye. MATERIALS AND METHODS The study was conducted on 50 patients, aged 40 years and above. History of dry e...

We compared the relative value of the tear film breakup time, Schirmer test, lactoferrin immunologic assay and rose bengal staining in 156 patients with varying severity of symptoms characteristic of keratoconjunctivitis sicca and in 39 controls. Statistical analysis showed that in patients with minimal ocular irritation the Schirmer test in combination with the lactoferrin immunologic assay pr...

  Introduction: There is a limited number of case reports published in the past decade confirming the radio-iodine presence in the tear. These observations as well as reported cases of salivary and lacrimal gland dysfunction after radioiodine therapy stimulated investigators to clarify whether lacrimal gland function can be affected post-radioiodine therapy. Hence we ...

PURPOSE To evaluate the tear film characteristics of spontaneous subconjunctival hemorrhage patients by Schirmer test I and tear interferometry. METHODS Forty-six spontaneous subconjunctival hemorrhage patients and 46 controls were enrolled in the study. Schirmer test I and tear interferometry were performed in all 92 subjects. The results obtained were compared between the two groups. RESU...
