World Sight Day – ROP Resource

This year, World Sight Day (October 10, 2024) focuses on children’s eye health around the world. We want to highlight and review the existing guidelines for the screening of retinopathy of prematurity (ROP). These guidelines, developed by key organizations in ophthalmology, aim to ensure early detection and management of ROP in preterm infants to prevent life-long visual impairment and blindness. Please note that this review reflects current clinical recommendations from leading bodies and is not a COS policy or official guideline.


Screening Eligibility

Screening is recommended for infants at the highest risk of developing ROP. The criteria include:

Initial screening: The first eye exam is recommended at either 31 weeks’ postmenstrual age in infants with gestational ages less than 26 6/7 weeks at birth, and at four weeks of chronological age in infants born with a gestational ages of 27 weeks or more, whichever is later.

Follow up intervals depend on the severity of the ROP observed in the initial exam.


As we recognize World Sight Day, it is important to remember that infants who develop ROP are at a higher risk of visual disorders such as: strabismus, amblyopia, high refractive errors, cataracts and glaucoma. By raising awareness and ensuring early detection and treatment, we can help protect the vision of these vulnerable children and work towards a world where everyone has access to eye care.

  3. To develop proficiency in a number of non-surgical procedures, including:
    • Laser Photocoagulation
    • Photodynamic Therapy (PDT):
    • Intravitreal and subTenons injections of pharmaceutical agents:
  4. To develop proficiency in surgical procedures, including:
    • Vitrectomy
    i. Retinal detachment repair
    ii. Macular cases
    iii. Vitreous hemorrhage
    • Scleral buckling techniques
    • Secondary intraocular lens cases
  5. To provide exposure to the evaluation of patients with suspected malignancy, the ancillary testing and evaluation of treatment options and management.
  6. To develop skills for lecturing to colleagues and residents on various aspects of medical and surgical retinal disease.
  7. To develop critical appraisal skills and to be aware of current and completed research in the area of medical retinal disease.

Research and Education:

The fellow will be expected to be involved with retina related basic and/or clinical research. Projects will be outlined for the fellow and they will be expected to present this at a national or international meeting. Dedicated time for research will be scheduled into rotation blocks as described above.

The fellow is expected to enhance resident teaching and clinical discourse among the department. Presentation of interesting/educational cases at grand rounds is expected. The fellow will perform 2 grand rounds presentations per academic year.

Application Process:

Interested applicants should send their curriculum vitae as well as 3 recent letters of reference from surgical mentors directly to Dr. Munir Iqbal at [email protected] or Mia O’Neil at mia.o’[email protected]

Applications to the Fellowship Programs must include the following:
• Letter of Intent
• Up-to-date Curriculum Vitae
• 3 Letters of Reference

Eligibility Requirements for Canadian and International Medical Graduates:

• Candidates must possess a medical degree from a University recognized by the Medical Council of Canada (MCC)
• Candidates must have completed an Ophthalmology residency that is recognized by the College of Physicians and Surgeons of Ontario (CPSO)
• International Medical Graduates do not need to write additional exams, but must be approved by the PGME Office at Western University

AstigMATIC: An Automated Vector Analysis Software 

AstigMATIC is a free standalone application for automated standardized astigmatism vector analyses in corneal and intraocular refractive surgeries. AstigMATIC allows the simultaneous display and analysis of astigmatism magnitude and axis.

The software produces the four following graphs according to current journal standards: 1-Target-Induced Astigmatism Vector, 2-Surgically-Induced Astigmatism Vector, 3-Difference Vector and 4-Correction Index. Vector means with standard deviations are automatically calculated and displayed on the corresponding single-angle vector plots (0 to 180°). The standard graphs can be easily exported as high-resolution TIFF images for figures to use in production and presentations.

The software can be downloaded at:
https://www.lasikmd.com/media/astigmatic/index.php.

The software was thoroughly tested, peer-reviewed and published in BMC Ophthalmology, the paper about the software is available at: https://bmcophthalmol.biomedcentral.com/articles/10.1186/s12886-018-0920-1

mEYEstro Automated Standard Outcomes Software 

mEYEstro is a user-friendly software that automatically generates standardized graphs for refractive surgery outcomes – as prescribed by JRS, JCRS, and Cornea Journals.

The software produces the following 11 standard graphs; Efficacy: 1. Cumulative uncorrected (UDVA) and corrected visual acuity (CDVA), 2. Difference between UDVA and CDVA, Safety: 3. Change in line of CDVA, Accuracy: 4. Spherical equivalent (SEQ) to intended target, 5. Attempted vs. achieved SEQ, 6. Defocus equivalent (DEQ) accuracy, 7. Refractive astigmatism accuracy, 8. Target-induced astigmatism vs. Surgically-induced astigmatism, 9. Correction index histogram, 10. Angle of error histogram, Stability: 11. SEQ stability over time. Percent proportions, means, standard deviations, Cohen’s d effect sizes, and p-values are calculated and displayed on each graph. All graphs can be easily exported as high-resolution TIFF images for figures to use in scientific manuscripts and presentations.

Organ Culture of Corneas and its Role in Eye Banking Economics

Date: Wednesday, November 30, 2022

Time: 4:00-5:30pm ET.

Presented by Dr. Graeme Pollock, Director of Lions Eye Donation Service, Centre for Eye Research Australia
Hosted by Gary Rockl, Tissue Innovation Specialist from Héma-Québec


The presentation will examine the technical aspects of organ culture of donor corneas and the benefits that may accrue through its adoption. It places this within the context of the forces affecting supply, demand and distribution of corneas in Australia.
• What are the technical requirements of organ culture?
• What are the benefits and disadvantages of the system?
• How does Australia approach national networking, self-sufficiency and sustainability in the provision of corneas for transplantation?

ESCRS Launches Online IOL Calculator

The developers’ goal was to create a free online tool that helps ophthalmologists aggregate the major online IOL calculators in one site, allowing them to get multiple results with only one data entry session.

“This will reduce typing mistakes, provide a better view, and allow users to compare results, eventually helping to get better refractive outcomes,” Dante Luis Buonsanti told EuroTimes.

The developers used a technique called web scraping. This is the sort of thing seen when using a hotel or air travel search engine. Web scraping uses bots to extract content from several websites and sends it to a single site. The user can then compare results from seven current calculators: Barrett Universal II, Cooke K6, Evo, Hill-RBF, Hoffer QST, Kane, and PEARL GDS. The site also “scraped” a comprehensive list of IOLs with optimized constants from IOL.com.
