Corneal topography in clinical practice.
Corneal topography in clinical practice. J Fr Ophtalmol. 2019 Nov 11;: Authors: Ghemame M, Charpentier P, Mouriaux F Abstract Developments in corneal topography allow for increasingly precise, detailed analysis of the corneal surface. This test is becoming indispensable in the treatment of complex corneas: keratoconus, corneal transplants, orthokeratology, etc. In refractive surgery, the combined analysis of the anterior and posterior cornea has permitted better screening for forme fruste keratoconus at risk for post-LASIK ectasia. Topography also assists in the calculation of premium intraocular lenses. Topography is an indispensable test for analyzing and following corneal disease.

Authors: Reisdorf S Abstract Machine learning and artificial intelligence are mostly important if data analysis by knowledge-based analytical methods is difficult and complex. In such cases, combined analytical and empirical approaches based on AI are also meaningful. The development and validation of several clinical parameters for the Corvis ST are a concrete example of this approach. In this article, the development of three screening parameters is described. It is shown how these developments lead to clinical solutions that can be beneficial for detecting clinical and subclinical keratoconus as well as for glau...
Conclusions: The use of alternate topical corticosteroids may be considered in cases of steroid-induced ocular hypertension after PKP because they offer good antiinflammatory prophylaxis with reduced hypertensive response.
Conclusions: Custom fast cross-linking, epi-on, rapid, narrowed beam apex-centered treatment of keratoconus with riboflavin–vitamin E TPGS produced a significant, rapid, and lasting cone progression stoppage, astigmatism reduction, and visual acuity improvement.
Purpose: To investigate the 1-year outcomes of using various corneal cross-linking (CXL) techniques for treating keratoconus. Methods: Setting: This is a prospective longitudinal cohort study performed at a tertiary academic medical center. Patient population: Six hundred seventy eyes of 461 patients with progressive keratoconus who underwent CXL were followed up for 1 year. Intervention: Eight combinations of CXL modalities were assessed, including 2 different CXL techniques (transepithelial or epithelium-off), 7 riboflavin formulations, and 2 ultraviolet-A protocols (conventional 3 mW/cm2 or accelerated 9 mW/cm2). P...
Conclusions: Repeated CXL seems to be effective in stabilizing keratoconus progression after failure of primary CXL. Patients should be followed up at least for 2 years after primary CXL.
Conclusions: Many of the corneal topographic and biomechanical variables in patients with severe OSAHS present different values from the general population with a trend toward KC values, such as keratoconus index or paired keratoconus index. Compared with the control group, significant differences were found in corneal volume, corneal elevation, and minimum radius.

ConclusionTonopen was the least affected from the corneal parameters followed by IOPcc and GAT. CRF was a strong determinant of tonometer variability.
Authors: Ghemame M, Charpentier P, Mouriaux F Abstract Corneal surface analysis is now more and more accurate. Corneal topography is a gold standard in corneal pathology follow-up: keratoconus, corneal grafts, orthokeratology. In refractive surgery, cornea ectasia post-Lasik must be avoided. Analyzing anterior and posterior surface can detect forme fruste keratoconus FFKC. Topography allows also better predictability of premium intraocular implants surgery. Topography is key examination and its interpretation is essential. PMID: 31780331 [PubMed - as supplied by publisher]
Conclusion: There is statistically significant co-existing prevalence of MVP and KC. Patients with KC are more likely to present with MVP, and patients with MVP are more likely to present with KC. PMID: 31782369 [PubMed - as supplied by publisher]
