Purpose. To evaluate the diagnostic performance of the McMonnies questionnaire as a screening survey for dry eye in Chinese outpatients. Methods. The questionnaire was self-administered by 27,999 patients with dry eye symptoms. A thorough ophthalmic examination including tear break-up time (TBUT), fluorescein staining, and Schirmer I test was completed to make a clinical diagnosis of dry eye. R...

introduction: the aim of this study was to eva-luate the salivation flow rate objectively using schirmer test and mouth dryness and other con sequences subjectively by distributing question naires to patients receiving head and neck radio therapy. materials and methods: in this descriptive study that was carried out at imam khomeini hospital, tehran, iran, the saliva flow rate of 33 patients re...

The lacrimal function has been evaluated in 23 patients suffering from primary biliary cirrhosis by rose bengal test, the Schirmer test 1, and the tear breakup time. Ocular dryness was present in 78% of cases studied. No difference was found with respect to the length or severity of the hepatic involvement between patients with and without lacrimal dysfunction, but in patients with signs of hyp...

BACKGROUND The Schirmer tear test (STT) is widely used in both human and veterinary ophthalmology. Two types of STTs have been developed: STT I and SST II. The STT I measures the basal and reflex tear production and is the most widely used STT. However, several factors influence the STT results such as the person performing the test and the location of the strip placement within the conjunctiva...

Purpose. To use optical coherence tomography (OCT) to evaluate the effect of punctal occlusion on tear meniscus volume in dry eye patients. Methods. Occlusion of both upper and lower puncta with collagen plugs was performed on one eye each in 20 dry eye patients and 20 normal subjects. The upper and lower tear menisci were imaged simultaneously by real-time OCT before punctal occlusion and on d...

AIM To detect and analyze the changes on ocular surface and tear function in type II diabetic patients with proliferative diabetic retinopathy (PDR), an advanced stage of diabetic retinopathy (DR), using conventional ophthalmic tests and the high-resolution laser scanning confocal microscopy. METHODS Fifty-eight patients with type II diabetes were selected. Based on the diagnostic criteria an...

Penurunan jumlah refleks berkedip berperan terhadap rendahnya produksi air mata dan secara temporer menimbulkan stres pada kornea mengakibatkan kering. Untuk mengurangi kemugkinan terjadinya kering ketika menggunakan komputer, dianjurkan untuk lebih sering menjaga kelembaban permukaan okular. Refleks yang tidak sempurna juga ditemukan pengguna komputer berdampak stabilitas mata. Tujuan peneliti...

PURPOSE To analyze in vivo corneal morphology and ultrastructural features in patients with classic Ehlers-Danlos syndrome (EDS). METHODS Fifty patients with classic EDS and 50 age- and sex-matched control subjects were studied. A clinical evaluation was made with the Ocular Surface Disease Index (OSDI) questionnaire and a complete ophthalmic examination, including assessment of the best-corr...

purpose: to compare tear secretion values following lasik (laser in situ keratomileusis) and photorefractive keratectomy (prk). methods: patients referred to aban eye clinic (isfahan, iran) for refractive surgery were randomly assigned to lasik or prk. exclusion criteria were contraindications for refractive surgery, usage of topical ocular drugs, dry eye and reoperation. schirmer test was perf...
