PURPOSE
Myopia is a major global health issue, especially among children and adolescents. Understanding its traits and progression is vital for proper management and prevention. This study aimed to fill a gap in research by analyzing demographic and refractive data concerning myopia among children and adolescents in Croatia, with the goal of providing insights into myopia prevalence, progression rates, and associated risk factors within the Croatian population.
DESIGN
This retrospective study utilized a comprehensive dataset from pediatric ophthalmology clinics at the University Eye Department, University Hospital "Sveti Duh," Zagreb, Croatia. The dataset included electronic medical records spanning from January 2008 to July 2023, encompassing demographic and refractive data.
METHODS
Data analysis focused on individuals aged 4 to 18 years who were diagnosed with primary myopia and/or compound myopic astigmatism. Ophthalmic examinations, including visual acuity tests, cycloplegic refraction, and assessments for eye comorbidities, were conducted by experienced pediatric ophthalmologists. Statistical analysis, including t-tests, survival analysis, and logistic regression, was performed to assess myopia prevalence, progression rates, and associated factors. These analyses were adjusted for covariates such as age, parental myopia, and gender.
RESULTS
The study included 895 individuals, 51 premyopes, 813 low myopes, and 31 high myopes. The average age of diagnosis was 11.37 ± 3.59 years for premyopes, 11.18 ± 3.53 years for low myopes, and 11.44 ± 4.35 years for high myopes. The fastest progression occurred in 2021 and 2022, -0.5 ± 0.12 D/y for premyopes and - 0.45 ± 0.1 D/y for low myopes. Premyopic progression to low myopia was associated with age 7-9 years (HR 2.42, 1.53 to 3.21) and both parents being myopic (HR 920.27. 850.16 to 950.53). Low myopic individuals with both myopic parents displayed the fastest 11-24 months after first visit progression rates, -0.69 (-0.52 to -0.87) D/y, while the 7-9 age group demonstrated -0.36 (-0.24 to -0.45) D/y. Low myopes aged 7-9 years with baseline SE between -6 D and -4 D were more strongly associated with ≤ - 0.5 D progression (OR = 2.0, 95% CI -1.00 to 2.39).
CONCLUSION
This study highlights the importance of environmental factors, genetics, and age in addressing myopia progression among Croatian youth, urging further research for effective local intervention strategies.

Review
BACKGROUND
Eugene Wolff (1896-1954) and Jonas S. Friedenwald (1897-1955) were life-long students and educators of anatomic pathology and ophthalmology. Both contributed toward narrowing the gap between the two rapidly diverging specialties of pathology and ophthalmology. Friedenwald in 1929 and Wolff in 1934 each published textbooks of ophthalmic pathology that influenced medical education for decades to come.
SUMMARY
Friedenwald's and Wolff's introduced ophthalmologists in training and practice to anatomic pathology, while familiarizing pathologists with the nature of ocular disease. Both books appeared at the time when anatomic pathology was departing from its mostly academic roles in education and research to assume more active participation in clinical care by establishing diagnoses through biopsy.
KEY MESSAGES
Wolff and Friedenwald dedicated their careers to teaching the art and science of anatomic pathology to clinical ophthalmologists. Their efforts helped anchor ophthalmology to the traditions of mainstream medicine.

INTRODUCTION
Mitogen-activated protein kinase kinase (MEK) inhibitors are targeted anticancer agents that are prescribed to treat a broad range of cancers. Despite their strong efficacy profile, MEK inhibitors have been associated with ocular toxicities, most notably, self-limited serous detachments of the neurosensory retina. In this report, we outline 3 cases of a rarely documented toxicity, MEK inhibitor-associated ocular hypertension.
CASE PRESENTATIONS
In the first case, a 69-year-old female with metastatic cholangiocarcinoma presented with an intraocular pressure (IOP) of 25 mm Hg right eye (OD) and 27 mm Hg left eye (OS) 2 months after starting trametinib therapy. Similarly, in the second case, a 26-year-old female with Langerhans cell histiocytosis presented with an elevated IOP of 24 mm Hg bilaterally (OU) 13 months after beginning treatment with an investigational MEK inhibitor. In the third case, a 46-year-old male with Langerhans cell histiocytosis presented with a new onset of elevated IOP of 24 mm Hg 21 days after initiating treatment with cobimetinib. All 3 patients' IOP returned to normal following dorzolamide/timolol administration and continued their cancer therapy.
DISCUSSION/CONCLUSION
This report presents 3 cases of elevated IOP in patients taking three distinct MEK inhibitors which would suggest that IOP-elevating effects exist across the class of MEK inhibitors. All 3 patients had a satisfactory response to topical pressure-lowering drops while continuing their life-preserving MEK inhibitor drug dose, indicating that discontinuation of therapy may not be necessary. Due to the increasing use of MEK inhibitors, it is important that ophthalmologists familiarize themselves with the broad range of potential adverse ocular effects of MEK inhibitors.

BACKGROUND
Programmed cell death-1 (PD-1) inhibitors and anti-angiogenic drugs have become a hotspot in research of anti-tumor programs; however, they can also cause some rare drug-related adverse reactions. Immune checkpoint inhibitors (ICIs) cause adverse reactions in the body, collectively known as immune-related adverse events (irAEs). Ocular side effects can occur in both targeted and immunotherapy patients, including dry eye, blurred vision, uveitis, conjunctivitis, retinopathy, or thyroid eye disease. To our knowledge, this is the first case report describing corneal ulcers secondary to dry eye in a patient treated with the combination of PD-1 inhibitor sintilimab and multi-targeted receptor tyrosine kinase inhibitor (TKI) anlotinib.
CASE DESCRIPTION
A 65-year-old woman with non-small cell lung cancer (NSCLC) and bone metastases, without pre-existing ocular conditions, experienced mild dry eye symptoms 1 month following treatment with sintilimab (200 mg q3w) in combination with anlotinib (12 mg q3w). Unrelieved dry eye symptoms occurred after the third cycle of chemotherapy, and she was diagnosed with dry eye syndrome. Subsequently, she received corneal protective lens, sodium hyaluronate eye drops, and prednisone treatment. Her corneal epithelial damage did not improve significantly, and within the following 2 months, her vision decreased in both eyes and progressed to bilateral corneal ulcers. Oral administration of sintilimab and anlotinib was interrupted, and treatments such as corticosteroids, anti-inflammatory drugs, and corneal repair were administered; however, both eyes presented with corneal subepithelial defect and corneal scarring. Due to a shortage of donors, no corneal transplantation surgery could be performed.
CONCLUSIONS
The development of corneal epithelial disorders in patients receiving target therapy and immunotherapy may not be reversed by reducing its dose. Although the condition is controlled with the use of glucocorticoids, some eye side effects cannot be cured. The timely detection and intervention of adverse effects of anti-tumor drugs by oncologists and ophthalmologists is critical for rational prescription. Ophthalmologists should be aware of eye side effects in patients using immunotherapy to ensure appropriate treatment and minimize potential eye complications such as dry eye, conjunctivitis, etc.

OBJECTIVE
To establish normative data for selected ocular diagnostic tests and commensal conjunctival microflora and describe the incidence of ocular pathology in Chilean flamingos.
ANIMALS STUDIED
A total of 41 Chilean flamingos were examined at the Blank Park Zoo in Des Moines, Iowa.
PROCEDURES
In 20 flamingos, blink rate was assessed undisturbed in their exhibit, then gentle manual restraint was used to assess palpebral fissure length (PFL), aqueous tear production (phenol red thread test [PRTT] in one eye, endodontic absorbent paper point tear test [EAPPTT] in the other), intraocular pressure (IOP; rebound tonometry), and fluorescein staining. Twenty-one other flamingos were brought to a darkened area for neuro-ophthalmic examination, slit lamp biomicroscopy, and indirect ophthalmoscopy. Swabs from seven flamingos were used for ocular microbiome evaluation.
RESULTS
Results are presented as mean ± standard deviation (range). Flamingos comprised 23 females/18 males, aged 11 ± 9.1 (0.7-40) years. Test results: blink rate, 3.7 ± 2 (1-9) blinks/min; PFL, 11.2 ± 1.2 (9-14) mm; IOP, 14 ± 3.2 (10-22) mmHg; EAPPT, 10.2 ± 2.8 (9-14) mm/min; PRTT, 6.8 ± 2.5 (3-13) mm/15 s. Dazzle reflex was positive in four birds examined. Pathologies included cataracts (n = 7 birds), corneal fibrosis (n = 3), endothelial pigment (n = 2), uveal cysts (n = 1), lens luxation (n = 1), and uveitis (n = 1). Ocular microbiome showed high diversity of taxa.
CONCLUSIONS
Baseline ocular parameters and incidence of ophthalmic pathology assist veterinarians with disease screening for Chilean flamingos, while the ocular microbiome showed high diversity.

INTRODUCTION AND IMPORTANCE
Purtscher retinopathy is the rare form of occlusive microvasculopathy, characterized by multiple retinal white areas around the optic nerve head and fovea with paravascular clearing and may be related to intraretinal hemorrhages. Acute Pancreatitis (AP) is one of the most common gastrointestinal reasons for hospital admissions globally. The complications of Acute Pancreatitis may include Purtscher's-like retinopathy, which has a low incidence rate of less than 0.24 instances per million cases. This case report highlights the value of thorough medical history taking and examination, and it apprises the consideration of ophthalmological manifestation in patients of Acute Pancreatitis.
CASE PRESENTATION
A 34-year-old female came to the emergency room due to intense abdominal pain associated with nausea and vomiting, which worsened over the last 24 h. The pain was described as continuous, sharp, and cramping-like in the upper abdomen, radiating to the back. Lab tests revealed elevated serum amylase and lipase levels, indicating pancreatitis, along with slight leukocytosis. A contrast-enhanced CT scan confirmed acute pancreatitis with mild inflammation and enlargement of the pancreas. Two days after admission, the patient experienced a sudden and painless loss of central vision in both eyes. There was no history of trauma or any other significant relevant history, other than pancreatitis. The ophthalmologist's examination found reduced visual acuity (6/60 in the right eye, 3/60 in the left eye), normal corneas, and anterior chambers.
DISCUSSION
Inkeles and Walsh established the first link between acute pancreatitis and Purtscher-like retinopathy when they reported three cases of the distinctive retinal appearance in individuals with acute pancreatitis in 1975.
CONCLUSION
The recovery and prognosis in cases of Purtscher-like retinopathy is variable and further research is required to ascertain the usage of corticosteroids and pentoxifylline in improving the course of a patient's with Purtscher's-like retinopathy.

PRCIS
About 1/4th of survey respondents from an ASCRS database initiate treatment for primary open-angle glaucoma (POAG) with laser trabeculoplasty. Factors impacting physicians' choice of laser versus topical treatment for POAG were explored.
PURPOSE
To characterize primary treatment preferences (topical medication vs. laser trabeculoplasty or intracameral sustained release implants) in primary open-angle glaucoma (POAG) patients and determine factors related to primary intervention selection.
METHODS
A 33-question survey was distributed to an American Society of Cataract and Refractive Surgery database on treatment choices made by ophthalmologists for POAG. Data collected included country of practice, years of practice, completion of glaucoma fellowship training, type of practice, and preference for first line of treatment of POAG. Multiple logit regression was used to compare the effect of covariates on physicians' choice of either topical medication or laser trabeculoplasty for POAG.
RESULTS
A total of 252/19,246 (1.3%) of surveys were returned. Almost three-quarters of respondents utilized topical medication as first line of treatment for POAG (73.6%) while 26.4% preferred to start with laser treatment. Significant variables associated with the selection of laser (vs. drops) are practicing in the U.S. (odds ratio [OR] 2.85, 95% confidence interval [CI] 1.33-6.10), more recent completion of ophthalmology residency (OR 1.95, 95% CI 1.00-3.77), greater volume of minimally invasive glaucoma surgeries (MIGS) (OR 1.68, 95% CI 1.18-2.40), and a glaucoma patient base greater than 25% (OR 2.21, 95% CI 1.09-4.48).
CONCLUSIONS
For the first line treatment of POAG, laser trabeculoplasty is more likely to be preferred, over topical drops, by U.S. physicians who are relatively new in practice, who have a larger glaucoma patient base and who perform more MIGS.

Review
A variety of systemic conditions involve the thorax and the eyes. While subtle or nonspecific eye symptoms can be the initial clinical manifestation of some disorders, there can be additional manifestations in the thorax that lead to a specific diagnosis and affect patient outcomes. For instance, the initial clinical manifestation of Sjögren syndrome is dry eye or xerophthalmia; however, the presence of Sjögren lung disease represents a fourfold increase in mortality. Likewise, patients with acute sarcoidosis can initially present with pain and redness of the eye from uveitis in addition to fever and parotitis. Nearly 90% of patients with sarcoidosis have thoracic involvement, and the ophthalmologic symptoms can precede the thoracic symptoms by several years in some cases. Furthermore, a diagnosis made in one system can result in the screening of other organs as well as prompt genetic evaluation and examination of family members, such as in the setting of Marfan syndrome or Ehlers-Danlos syndrome. Multimodality imaging, particularly CT and MRI, plays a vital role in identification and characterization of these conditions. While it is helpful for ophthalmologists to be knowledgeable about these conditions and their associations so that they can order the pertinent radiologic studies, it is also important for radiologists to use the clues from ophthalmologic examination in addition to imaging findings to suggest a specific diagnosis. Systemic conditions with thoracic and ophthalmologic manifestations can be categorized as infectious, inflammatory, autoimmune, neoplastic, or hereditary in origin. The authors describe a spectrum of these conditions based on their underlying cause. RSNA, 2024.

Molecular Genetics & Genomic Medicine Jun 2024To characterize the phenotype and genotype of a Chinese family with autosomal-dominant retinitis pigmentosa (RP) accompanied by iris coloboma.
PURPOSE
To characterize the phenotype and genotype of a Chinese family with autosomal-dominant retinitis pigmentosa (RP) accompanied by iris coloboma.
METHODS
The proband, a 34-year-old male, was examined with his family by using fundus photography, optical coherence tomography (OCT), autofluorescence, and full-field electroretinography (ffERG). Genetic analyses were conducted through whole-exome sequencing (WES) to screen for variations.
RESULTS
Three members of this Chinese family were shown to be bilateral iris coloboma. The male proband and his mother exhibited typical RP feature. The proband's late grandfather had been documented manifestation of iris coloboma. The mode of inheritance was confirmed to be autosomal dominance. Through linkage analysis and WES, a heterozygous variation in the miR-204 gene (n.37C>T), a noncoding RNA gene, was identified in these three members.
CONCLUSIONS
In this third independent and the first Asian family, the existence of a miR-204 variant associated with RP accompanied by iris coloboma was confirmed. Our findings reinforce the significance of miR-204 as an important factor influencing visual function in the retina. When phenotypes like RP accompanied by iris coloboma in an autosomal-dominant pattern, including in Chinese patients, miR-204 aberrations should be considered.

Review
Optic neuritis (ON) is an inflammation of or around the optic nerve, frequently caused by infectious or immune-mediated inflammatory disorders. In the UK, its strongest association is with Multiple Sclerosis (MS), though the combined prevalence of other associated infectious and immune-mediated inflammatory diseases (I-IMID) is similar to that of MS-ON. Prompt identification and understanding of ON's underlying cause informs tailored management and prognosis. Several IMIDs linked to ON, such as aquaporin-4 antibody-associated optic neuritis (AQP4-ON), myelin oligodendrocyte glycoprotein antibody-associated optic neuritis (MOG-ON), and neuro-sarcoidosis, show remarkable response to corticosteroid treatment. Therefore, urgent investigation and treatment are crucial in cases 'atypical' for MS-ON. Following the 1992 Optic Neuritis Treatment Trial, clinical practice has evolved, with short-course high-dose corticosteroids considered safe and effective for most people. Timely recognition of patients who could benefit is critical to avoid irreversible vision loss. This review provides a practical guide and a summary of evidence on the investigation and management of acute optic neuritis. It reflects the knowledge and limitations of current evidence, framed through the neuro-ophthalmic perspective of clinical practice at multiple UK academic centres.
