“…Therefore, surgical treat ment may be required such as wedge resection, lamellar crescent resection, intracorneal rings or grafting techniques like lamellar or penetrating 3 3 3 keratoplasty. 1,14 We performed lamellar crescent wedge resection and primary suturation to avoid the risks of penetrating keratoplasty.…”

“…It could be useful to evaluate the efficacy of surgery practiced on the peripheral cornea. Meanwhile, it is also capable of monitoring patients with peripheral corneal diseases, such as pellucid marginal corneal degeneration (PMCD), which usually thins the cornea from the 4 o'clock position to the 8 o'clock position, 1-2 mm from the limbus [47,48]. With regard to clinical routine examinations as well as experimental techniques, the utility of any instrument strongly depends on the repeatability and reproducibility of measurements.…”

Purpose: To investigate the repeatability and reproducibility of mapping the entire corneal thickness using spectral domain optical coherence tomography (SD-OCT). Methods: Thirty normal eyes, 30 post-laser in situ keratomileusis (LASIK) surgery eyes, and 30 keratoconus eyes were analyzed. A custom-built long scan depth SD-OCT device was used to obtain entire corneal images. Ten-millimeter-diameter corneal thickness maps were generated by an automated segmentation algorithm. Intraclass correlation coefficients of repeatability (ICC₁) and reproducibility (ICC₂), and coefficients of repeatability (CoR₁) and reproducibility (CoR₂), were calculated to quantify the precision and accuracy of corneal pachymetry measurements using the Bland-Altman method. Results: For SD-OCT measurements in healthy subjects, CoR₁ and CoR₂ were less than 5.00 and 5.53 μm. ICC₁ and ICC₂ were more than 0.997 and 0.996. For SD-OCT measurements in LASIK patients, CoR₁ and CoR₂ were less than 5.09 and 5.34 μm. ICC₁ and ICC₂ were more than 0.997 and 0.996. For SD-OCT measurements in keratoconus patients, CoR₁ and CoR₂ were less than 11.57 and 10.92 μm. ICC₁ and ICC₂ were more than 0.995 and 0.996. Conclusions: The measurements of corneal pachymetric mapping by long scan depth SD-OCT can be assessed over the entire corneal area with good repeatability and reproducibility.

Purpose: To summarize the recent trends in the treatment of pellucid marginal degeneration (PMD) based on available published data.Method and literature search: A PubMed search was conducted with combinations not limited to the following search terms: Pellucid marginal degeneration, Corneal ectasia, Corneal collagen cross-linking (CXL), Intracorneal ring segments (ICRS), Contact lens, Keratoplasty in corneal ectasia. A review of the search results was performed and relevant articles to the topic were included. Summary:Ophthalmologists have got a wide array of therapeutic modalities for the management of PMD. However, the key to optimal treatment is careful clinical assessment of patients and their visual requirements and tailoring the treatment to individual patients.
