The article reports on updates in the use of artificial intelligence (AI) technology, particularly machine learning, for early detection and treatment of ectatic corneal diseases. Other topics include the distinctive signs of advanced ectasia like Vogt striae and Fleischer ring, and the conventional methods of diagnosing the diseases like slit-lamp examination and the Placido disc-based corneal tomography.

The article offers information on the first annual International Keratoconus Academy of Eye Care Professionals (IKA) Keratoconus Symposium "Front to Back and Everything In Between," to be held in Scottsdale, Arizona on April 22 and 23, 2023.

The article focuses on the importance of eye banking and human ocular tissues in ophthalmic research. It states that animal models has played a significant role in ophthalmic research in past and adds that they have several disadvantages including physiological and pathological differences as compare to human ,short life spans and the creation of an artificial system for the experiments. It also discusses several studies that are in the initial stage for the treatment of several eye diseases. INSET: Seven Facts About Ocular Tissue Donation.

The article discusses a study which evaluated the long-term effects of the SMILE Xtra (Carl Zess Meditec) in patients who had abnormal topography, low residual stromal bed thickness, higher refractive errors, and thin preoperative corneal thickness. Topics include inclusion criterion for the SMILE Xtra candidates, efficacy index for the SMILE Xtra treatment, and safety, stability, and predictability of the Xtra procedure.

The article discusses the Relational Thickness Altered (RTA) analytical tool for identifying the impact of the laser-vision-correction (LVC) procedure on the cornea when assessing the ectasia complication risk before laser vision correction. It cites the patient's central corneal thinnest point (TP) in accurately calculating the residual stromal bed (RSB) and the percentage of tissue altered (PTA), and in assessing ectasia risk. Also noted is RTA's better determination of the LVC impact.

The article discusses the importance of timing in the quick repair of retinal detachments (RD). Topics covered include the development of cystoid macular edema and retinal degeneration after detachment, such preoperative factors as duration, height, and technique that determine retinal recovery in humans, and other factors like persistent fluid and macular displacement. Also noted is the patient's poor outcome if surgery is delayed.

The article discusses diagnostic technologies that can help ophthalmologists provide proper counseling of patients and avoid potential complications of refractive surgery. Some of the diagnostic technologies are slit lamp biomicroscopy with digital documentation, Scheimpflug tomography and ocular wavefront. Doctor Renato Ambrósio Jr. comments on the need for refractive surgeons to understand the different diagnostic technologies and how and when to use them for patients.

The article reports on a study of a large number of consecutive primary LASIK treatments with more than 300,000 procedures done between 2007 and 2011. At the time of surgery, 38 percent of ectasia patients were over the age of 30. The researchers reviewed the preoperative topography of all ectasia cases and a subset of the cohort treated in 2007 who did not develop ectasia. The review was based on established pattern recognition of the sagittal topographic maps.

The article focuses on an ongoing battle between ophthalmology practices and insurance companies for a broader coverage and fair reimbursement of corneal collagen crosslinking (CXL). Topics discussed include the high cost of the CXL procedure, the advantage of a broader coverage for patients, and information on treatment options currently being studied.

The article reports that a preliminary analysis of a dataset with over 300,000 eyes treated with LASIK between six to 10 years is starting to quantify some of the risks involved. Topics mentioned include thoughts from initial principal investigator Steven C. Schallhorn, M.D. about the analysis, age and corneal shape before surgery as risk factors for ectasia, and distinction between the entire cohort and ectasia patients according to topography.

When a schoolmate goes missing, Hilda seeks help in finding her from Molly and Lottie, "a well-respected pathologist and an excellent curator of the necro-museum she personally established", who has her own YouTube channel. Lottie and her posse of followers soon discover that other young girls have gone missing. The blood-drenched finale and disturbingly creepy epilogue will long remain in the mind of the reader.

The article reports on the topic discussed by Dr. J. Bradley Randleman at the annual meeting of the American Society of Cataract and Refractive Surgery in 2012. Dr. Randleman talked about the risk factors for ectasia and the Ectasia Risk Score System (ERSS). He said that age, topographic abnormalities, and stromal bed thickness are relevant factors for the development of the disease after laser-assisted in situ keratomileusis (LASIK).

The article discusses a study by Avi Wallerstein and Mark Cohen, co-founders of laser vision correction provider LASIK MD, which revealed that the progressive corneal ectasia can be treated with multimodal technique. It highlights that the multistep treatment involving phototherapeutic keratotomy (PTK), topography-guided PRK (TG-PRK) and collagen crosslinking (CXL) is advantageous for ectatic corneas. It mentions that the treatment improves keratometry, refraction, and quality of vision.

The article presents a case study of 32-year old female who had Laser-Assisted in situ Keratomileusis (LASIK) for moderate myopia, which was followed by central corneal steepening. She was diagnosed with iatrogenic ectasia, which was successfully cured by collagen crosslinking (CXL). The article also discusses alternative CXL procedures and visual rehabilitation.

The article reports on the study by Doctor Simon P. Holland of University of British Columbia in Vancouver, on the efficacy of topography-guided photorefractive keratectomy (TG-PRK) and corneal collagen crosslinking (CXL) for patients who are at high risk with postLASIK ectasia.

The article focuses on corneal collagen crosslinking (CXL) with laser-assisted in situ keratomileusis (LASIK). It says that combing CXL with LASIK may not be an approach in the prevention of postoperative ectasia. It states that the routine addition of CXL to LASIK gives complications, including corneal infiltrates, endothelial cell damage or loss, and corneal scarring. It adds that it is unknown how CXL will affect the refractive outcome of LASIK and stability of the treatment.

The article reports on the topic discussed by Dr. Lewis R. Groden at the annual meeting of the American Society of Cataract and Refractive Surgery in 2012. Dr. Groden talked about a retrospective chart study which evaluated a series of unpublished post-laser vision correction (LVC) ectasia cases. He said that the study's results indicated the need for further research in order to know the risk factors for ectasia. INSET: Take-Home Message.

The article discusses research on the prevalence of colorectal adenomas in younger adults and adults aged 50 years and older. It references a study published in a 2008 issue of "Clinical Gastroenterology and Hepatology." An epidemiologic necropsy in serial autopsy patients to assess the prevalence of colorectal adenomas in young adults compared with older adults was conducted. The study found an increase in the prevalence of adenomas from 10.1 to 12.06 per 100 autopsies in the sixth and ninth decades of life in older adults.
