Prevalence of strabismus and risk factors in adults born preterm with and without retinopathy of prematurity: results from the Gutenberg Prematurity Eye study
CONCLUSION: Low GA and refraction of the eye are independent risk factors for strabismus, which typically occurs in the first 10 years of life. Perinatal adverse events are the most important factors for the presence of nystagmus in adulthood.PMID:38503479 | DOI:10.1136/bjo-2023-324698 (Source: The British Journal of Ophthalmology)

Heimler syndrome with a complaint of blurred vision caused by compound heterozygous variants in < em > PEX1 < /em >
CONCLUSION: Heimler syndrome is caused by compound heterozygous PEX1 pathogenic variants, c.2966T > C (p.I989 T) and c.1671_1672del (p.G558Sfs*33), which contributed to the diversity of clinical and genetic profiles in this patient. The main clinical manifestations include bilateral retinitis pigmentosa with cystoid macular edema, sensorineural hearing loss, and enamel hypoplasia. Systemic examinations are suggested for patients suspected of having pigmentary retinal dystrophy, especially combined with hearing-related impairments. Genetic testing can help us to make a definitive diagnosis.PMID:38488462 | DOI:10.1177/112...

Experiences of keratoconus patients attending public eye care facilities in South Africa
CONCLUSION: Patients with KC received inadequate information on their condition due to limited health literacy and vocabulary barriers. Programmes to promote practitioner and patient education are required to improve the perceived service level provided to KC patients.Contribution: The findings of this study will assist to improve the experiences of KC patients on perceived service quality received from public facilities.PMID:38426773 | DOI:10.4102/phcfm.v16i1.3974 (Source: Primary Care)
