The PROS layer at the foveal center was thinner in patients who had diabetic retinopathy or diabetic macular edema than both the healthy volunteers and diabetic patients without retinopathy.
Purpose. To evaluate the depth of corneal stromal demarcation line using AS-OCT and confocal microscopy after two different protocols of accelerated corneal collagen cross-linking procedures (CXL). Methods. Patients with keratoconus were divided into two groups. Peschke CXL device (Peschke CCL-VARIO Meditrade GmbH) applied UVA light with an intended irradiance of 18.0 mW/cm2 for 5 minutes after applying riboflavin for 20 minutes (group 1) and 30 minutes (group 2). One month postoperatively, corneal stromal demarcation line was measured using AS-OCT and confocal microscopy. Results. This study enrolled 34 eyes of 34 patients (17 eyes in group 1 and 17 eyes in group 2). The mean depth of the corneal stromal demarcation line was 208.64 ± 18.41 μm in group 1 and 240.37 ± 18.89 μm in group 2 measured with AS OCT, while it was 210.29 ± 18.66 μm in group 1 and 239.37 ± 20.07 μm in group 2 measured with confocal microscopy. Corneal stromal demarcation line depth measured with AS OCT or confocal microscopy was significantly deeper in group 2 than group 1 (P < 0.01). Conclusion. The group in which riboflavin was applied for 30 minutes showed significantly deeper corneal stromal demarcation line than the group in which riboflavin was applied for 20 minutes.
Aim: It is aimed to evaluate the visual performance of Rose K and Conflex Air rigid gas-permeable (RGP) contact lenses in keratoconus subgroups according to cone types, cone location, and severity of keratoconus.
Materials and Methods:Seventy-five eyes of 75 participants were included in this retrospective study. Each participant received a full ophthalmologic examination involving refraction, uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BCVA), slit-lamp biomicroscopy-fundoscopy, break-up time (BUT), corneal topography, best contact lens corrected visual acuity (BCLCVA).
Results
Conclusion:Both contact lenses may improve visual acuity in patients with all subtypes of keratoconus. Rose K contact lens may be better in globus type of keratoconus then oval type.Keywords: Contact lens, rigid gas permeable contact lens, keratoconus.
Öz
Amaç: Rose K ve Conflex Air sert gaz geçirgen kontakt lenslerinin görsel performansını keratokonus alt gruplarındaki kon tipi, kon lokasyonu, hastalık şiddetinin değerlendirilmesi amaçlandı.
Gereç ve Yöntem: Yetmiş beş hastanın 75 gözü geriye dönük çalışmaya dahil edildi. Her hastaya refraksiyon, düzeltilmemiş görme keskinliğ, gözlükle en iyi düzeltilmiş görme keskinliği, yarıklı-lamba biyomikroskopisifundoskopisi, göz yaşı kırılma zamanı, korneal topografi, kontakt lens ile en iyi düzeltilmiş görme keskinliğini içeren tam bir oftalmolojik muayene yapıldı.Bulgular: Ortalama yaş 25. 9±8.3 (aralık 18-53) idi. Otuz altı göze Rose K, 39 göze Conflex Air uygulandı. Rose K grubunda; ortalama logMAR UCVA, BCVA, ortalama logMAR UCVA, BCVA,
