Peters anomaly is characterized by a defect in the development of the anterior segment of the eye during fetal development (Anterior segment dysgenesis). This anomaly presents a broad clinical presentation ranging from minimal peripheral corneal opacity to extensive adhesions of the iris and lens with dense central corneal opacity that impairs vision. Peters Plus Syndrome is a recessive autosomal syndrome manifested by Peters anomaly, along with systemic disorders such as brachydactyly (short fingers and toes), short stature, a developmental delay, dysmorphic facial features, and may accompanied with heart and genitourinary malformations.

Methods: Retrospective study of consecutive paediatric patients who underwent uneventful cataract extraction surgery along with in-the-bag IOL implantation between 2012 and 2018 in the Hospital for Sick Children, Toronto, Ontario, Canada. The accuracy of five different IOL formulae, including the BUII, Sanders-Retzlaff-Kraff Theoretical (SRK/T), Holladay I, Hoffer Q and Haigis, was evaluated.
Objective: To present the outcomes of attempts to salvage total graft detachment following Descemet's membrane endothelial keratoplasty (DMEK).
Methods: A search of the electronic medical records of two tertiary medical centers for all patients who underwent DMEK yielded six cases of postoperative total graft detachment (2.54%).
Article Synopsis
- Keratoglobus is a rare eye condition causing corneal thinning and bulging, leading to vision loss and potential corneal perforation, but its genetic causes are not yet known.
- The study analyzed 3 families with keratoglobus to identify its genetic basis, involving advanced sequencing techniques and mouse models.
- Results revealed that mutations in the TMEM45A gene are associated with the disorder, with significant gene expression differences observed in affected corneas compared to healthy tissue.
Purpose: The aim of this study was to characterize the wide phenotypic spectrum of Peters anomaly and to suggest a management algorithm based on disease phenotype.
Methods: The charts of all children diagnosed with Peters anomaly between January 2000 and December 2013 were reviewed retrospectively. Anterior segment color photographs, anterior segment optical coherence tomography, and ultrasound biomicroscopy images were used to phenotype disease severity and to guide management.
Purpose: To compare keratometry data between the handheld Retinomax K-plus 3 and the table-mounted IOLMaster 700.
Methods: Healthy adult volunteers were prospectively recruited to the study. All participants underwent 3 consecutive keratometry measurements using the Retinomax K-plus 3 and a single biometry assessment using the IOLMaster 700.
: To evaluated Descemet's membrane endothelial keratoplasty (DMEK) outcomes in young and old graft recipients.: Data of 164 surgeries with a median age of 76 years (interquartile range 14 years) undergoing DMEK surgery between 2016 and 2018 was reviewed. Complications, graft survival, and visual acuity gain were compared between subjects in the 25th percentile (young recipients; aged 70 years and less, n = 21) and 75th percentile (old recipients; aged 85 years and over, n = 27) over the 2-year follow-up.

Methods: One hundred and eleven eyes of 111 patients with wet AMD underwent cataract surgery at Helsinki University Hospital in Finland during 2014-2018.
Objective: To evaluate the symptoms and signs of dry eye disease (DED) in children diagnosed with blepharokeratoconjunctivitis (BKC).
Design: Prospective case-controlled study PARTICIPANTS: Consecutive patients with BKC and normal controls.
Methods: All participants underwent a comprehensive dry eye assessment including the Canadian Dry Eye Assessment (CDEA) questionnaire, tear film osmolarity test, Schirmer's test without anesthesia, slit lamp examination, tear film break-up time, corneal fluorescein staining (CFS), and lissamine green conjunctival staining (LGCS), according to the Sjögren's International Collaborative Clinical Alliance ocular staining score.
