PURPOSE: We aimed to compare the tear meniscus measurements using strip meniscometry (SM) and Keratograph5M (K5M) between 3 subtypes of dry eye disease patient groups, classified according to the presence of meibomian gland dysfunction (MGD), and normal subjects. METHODS: We enrolled 145 eyes from 145 subjects and measured the tear meniscus using SM and K5M, tear film breakup time, ocular surface staining, and ocular surface disease index; the Schirmer test; and examined lid margins and meibomian glands...

PURPOSE: To investigate automated values from an advanced corneal topographer with a built-in real keratometer, color camera, and ocular surface interferometer for the evaluation of non-Sjögren dry eye syndrome (NSDES) with meibomian gland dysfunction (MGD). METHODS: Sixty-four patients (64 eyes) diagnosed with NSDES with MGD were enrolled. All eyes were evaluated using the Ocular Surface Disease Index (OSDI), fluorescence staining score, tear film breakup time (TBUT), Schirmer test, and MGD grade...

Dry Eye Disease (DED) is "a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance, and tear-film instability with potential damage to the ocular surface." DED comprises two etiologic categories: aqueous-deficient dry eye (ADDE) and evaporative dry eye (EDE). Diagnostic workup of DED should include clinical history, symptom questionnaire, fluorescein TBUT, ocular surface staining grading, Schirmer I/II, lid and meibomian pathology, meibomian expression, followed by other available tests...

Objective: To assess the application of Keratograph 5M in evaluating tear film and meibomian gland function in patients with dry eye. Methods: A total of 144 eyes were recruited in the study, in which 72 eyes were from patients diagnosed with dry eye and 72 eyes were from healthy subjects. All subjects finished following tests or examinations:ocular surface disease index (OSDI) to evaluate eye symptoms; Keratograph 5M examination to obtain tear meniscus height (TMH), noninvasive tear break-up time (NIBUT) including first NIBUT (NIBUT-Fir) and average NIBUT (NIBUT-Ave), and infrared meibography; and fluorescein sodium staining to obtain fluorescein tearbreak-up time (FBUT)...

BACKGROUND: It is difficult to standardize assessment of dry eye in different clinical settings. Increasingly, tear stability is recognized to be important for the definition and assessment of patients with dry eye. Recently, two commercially available instruments have been made available for objectively measuring noninvasive tear break-up time (NIBUT), as an indicator of tear stability: the Tomey RT-7000 Auto Refractor-Keratometer and Oculus Keratograph (K)5M. We aim to assess the agreement of NIBUT measurements using these modalities...

PURPOSE: To evaluate the applicability of the fourth-generation OCULUS keratograph in measuring lower tear meniscus height. METHODS: Seventy cases (140 eyes) with dry eye disease and 37 controls (74 eyes) were enrolled. Tear breakup time (TBUT), Schirmer test I, and corneal fluorescein staining were examined. The images of lower tear meniscus were obtained by OCULUS keratograph. The tear meniscus height was measured and its correlation with traditional tear film diagnostic tests were analyzed...

The aim of the study is to evaluate corneal asphericity in three diameters of 5, 6, and 7 mm, and to assess the effect of age, refractive error, and gender on asphericity. The study included 500 healthy subjects with a mean ± SD age of 29.51 ± 11.53 years. All analyses were based on the right eyes of the patients. Topographic data were analyzed using Oculus Keratograph 4. Mean ± SD corneal asphericity values of the study population in 5, 6, and 7 mm diameters were -0.21 ± 0.11, -0.24 ± 0.10, and -0...

INTRODUCTION: Meibomian gland dysfunction is a common cause of dry eye syndrome which can also lead to eyelid inflammation. Today, diagnostics of meibomian glands is not fully automatic yet and is based on a qualitative assessment made by an ophthalmologist. Therefore, this article proposes a new automatic analysis method which provides a quantitative assessment of meibomian gland dysfunction. METHOD: The new algorithm involves a sequence of operations: image acquisition (acquisition of data from OCULUS Keratograph® 5M); image pre-processing (image conversion to gray levels, median filtering, removal of uneven lighting, normalization); main image processing (binarization, morphological opening, labeling, Gaussian filtering, skeletonization, distance transform, watersheds)...

Purpose. To determine the intraexaminer repeatability and interexaminer reproducibility of tear meniscus height (TMH) and noninvasive Keratograph tear breakup time (NIKBUT) measurements obtained with the Keratograph 5M (K5M) in a sample of healthy and dry eye populations. Methods. Forty-two patients with dry eye disease (DED group) and 42 healthy subjects (healthy group) were recruited in this prospective study. In all subjects, each eye received 3 consecutive measurements using the K5M for the TMH and NIKBUTs (NIKBUT-first and NIKBUT-average)...

PURPOSE: We consider whether quantification of ocular bulbar redness, using image processing of relative Red-channel activity (Red-value), can be applied to a clinical sample and how this approach compares to an automated bulbar redness grading technique (Oculus Keratograph 5M, R-scan). METHODS: Red-values from dry eye patients (n = 25) were determined using image processing of digital photographs over the nasal bulbar conjunctiva. Red-values were compared with subjective grades from six clinicians who graded the images using the IER scale...

PURPOSE: To study the repeatability and reproducibility of tear meniscus height (TMH) measurements obtained with a keratograph and Fourier domain optical coherence tomography (FD-OCT) and to assess their agreement in patients with dry eye. METHODS: Sixty-four eyes with dry eye were analyzed by the Schirmer test, tear breakup time test, and fluorescein corneal staining. The TMH was measured 3 times using both devices by 2 different examiners. The repeatability and reproducibility of measurements were assessed by within-subject standard deviation (Sw), repeatability (2...

PURPOSE: To determine the repeatability and agreement between the noninvasive Keratograph tear break-up time (NIK-BUT) as measured by the Oculus Keratograph 4 and fluorescein tear break-up time (FBUT). METHODS: Sixty subjects were recruited for two study visits separated by 7 (± 2) days. At each visit, three NIK-BUT measures and FBUT measures were obtained. Each NIK-BUT measure from the Keratograph included a first and an average NIK-BUT. The means of the measures obtained, first NIK-BUT, and average NIK-BUT and FBUT were calculated for each visit...
