    1. The effect of epiretinal membrane surgery on macular microvasculature: an optical coherence tomography angiography study

      The effect of epiretinal membrane surgery on macular microvasculature: an optical coherence tomography angiography study

      Purpose To investigate both the possible effects of both idiopathic epiretinal membrane (IERM) itself and surgery on macular microvascular structure using optical coherence tomography angiography (OCT-A) and to determine the associations with structural and visual outcomes. Methods Twenty-four eyes of 24 patients with IERM and 24 eyes of 12 healthy controls were included. Vascular parameters, including the superficial capillary plexus (SCP) and deep capillary plexus (DCP) were evaluated by OCT-A prior to and 6 months after ERM removal. The foveal avascular zone (FAZ, mm 2 ) area, parafoveal vascular density (VD, %) and flow area (mm 2 ) measurements were used to evaluate ...

    2. Choroidal thickness measurements with optical coherence tomography in branch retinal vein occlusion

      Choroidal thickness measurements with optical coherence tomography in branch retinal vein occlusion

      AIM : To evaluate central macular thickness (CMT) and mean choroidal thickness (MCT) in eyes with branch retinal vein occlusion (BRVO), before and after ranibizumab treatment using spectral domain-optical coherence tomography (SD-OCT). METHODS : Forty-two patients with unilateral BRVO and macular edema were included in this study. There were 25 men and 17 women. Using SD-OCT, choroidal thickness was measured at 500 ?m intervals up to 1500 ?m temporal and nasal to the fovea. MCT was calculated based on the average of the 7 locations. All the eyes with BRVO were treated with intravitreal ranibizumab (0.5 mg/0.05 mL). Comparisons ...

    3. Evaluating Choroidal Characteristics in Systemic Sclerosis Using Enhanced Depth Imaging Optical Coherence Tomography

      Evaluating Choroidal Characteristics in Systemic Sclerosis Using Enhanced Depth Imaging Optical Coherence Tomography

      Purpose : To evaluate choroidal thickness (CT) and investigate the involvement of choroidal circulation in patients with systemic sclerosis (SSc). Methods : A total of 120 eyes of 60 SSc patients and 60 eyes of 30 healthy controls were evaluated. CT measurements were performed at the subfoveal region, 1000 µm nasal and 1000 µm temporal to the fovea, using enhanced depth imaging optical coherence tomography. CT measurements were compared between the patients and controls. Results : The average subfoveal, parafoveal nasal and parafoveal temporal CT were significantly thinner in SSc patients when compared with healthy controls (297.77 ± 60.8 µm vs 339 ...

    4. Interexaminer Reproducibility of Optical Coherence Tomography for Measuring the Tear Film Meniscus

      Interexaminer Reproducibility of Optical Coherence Tomography for Measuring the Tear Film Meniscus

      Purpose : New optical coherence tomography (OCT) devices with anterior segment module are able to measure the tear meniscus height (TMH) and tear meniscus area (TMA). Since the borders of the area and the height are to be marked by an examiner, the measurements are prone to be subjective. Herein, we aimed to evaluate the interexaminer reproducibility of the tear meniscus measurements with OCT. Materials and Methods : In this prospective cross-sectional study, both eyes of 300 consecutive patients with and without dry eye were studied. Following routine ophthalmologic examination, tear-film OCT images were obtained. Two examiners, who were unaware of the ...

    5. Assessment of Tear Meniscus with Optical Coherence Tomography in Thyroid-Associated Ophtalmopathy

      Assessment of Tear Meniscus with Optical Coherence Tomography in Thyroid-Associated Ophtalmopathy

      Purpose : To evaluate the tear -film meniscus with optical coherence tomography (OCT) in patients with Graves’ disease (GD). Materials and methods : Patients with GD without clinical features of thyroid-associated ophthalmopathy (TAO) (Group 1, n  = 35), patients with signs of TAO (Group 2, n  = 31) and healthy participants (Group 3, n  = 31) were enrolled. Palpebral fissure width, Schirmer test, tear break-up time (TBUT) test and tear -film meniscus height and area obtained with Fourier-domain-OCT were analyzed. Results : TBUT test scores were 8 s (2–25) in Group 1, 8 s (2–15) in Group 2 ( p  = 0.380); and10 s (5 ...

    6. Optical Coherence Tomography for Measuring the Tear Film Meniscus: Correlation with Schirmer Test and Tear-Film Breakup Time

      Optical Coherence Tomography for Measuring the Tear Film Meniscus: Correlation with Schirmer Test and Tear-Film Breakup Time

      urpose : To compare tear meniscus height (TMH) and area (TMA) values obtained by optical coherence tomography (OCT) with the Schirmer test and tear-film break-up time (TBUT) values. Materials and methods : In this prospective cross-sectional study, the right eyes of 300 consecutive patients were studied. All patients underwent routine ophthalmologic examination. Schirmer and TBUT measurements were taken, and tear-film OCT images were obtained. Using OCT, the TMH (i.e. the line connecting the intersection of the meniscus with the cornea and eyelid) and cross-sectional TMA were calculated. Patients were divided into Groups 1 (Schirmer values ≤5 mm) and 2 (Schirmer values ...
