Congenital iris ectropion is an uncommon malformation of the anterior segment of the eye. The authors describe a case of bilateral congenital iris ectropion associated with juvenile glaucoma in an otherwise healthy 9-year-old girl. Intra-ocular pressure (IOP) measured by Goldmann applanation tonometry was 40 mmHg in the right eye and 32 mmHg in the left eye. Despite maximum IOP lowering therapy, the desired IOP levels needed to prevent further progression of the glaucoma could not be achieved. Visual field testing and confocal scanning laser tomography showed glaucomatous neuropathy. Trabeculectomy with antimetabolites (mitomycin C 0.2 mg/ml) was performed in both eyes and IOP was normalized without IOP lowering medications during a follow-up of 4 years. The authors point out the importance of recognizing congenital iris ectropion early to prevent blindness in young patients and improve their prognosis.

An 18-year-old woman with a congenital iris stromal cyst was referred for sudden-onset increased intraocular pressure (IOP) that did not respond to medical therapy. Ultrasound biomicroscopy demonstrated synechial angle closure from 9:00 to 12:00 in addition to a large cyst occupying much of the inferior angle. After implantation of an Ahmed glaucoma valve, her visual acuity returned to baseline, and IOP normalized.

Background: Anterior segment dysgenesis (ASD) encompasses a range of congenital disorders affecting the development of the eye's anterior segment, often leading to significant visual impairment and glaucoma. Although numerous studies have focused on the genetic basis of ASD, few have comprehensively compared the clinical features across ASD subtypes. This study aims to address this gap by describing and comparing the clinical characteristics and ultrasound biomicroscopy (UBM) imaging features of various ASD subtypes in a Chinese tertiary medical center.

Background: Oculocutaneous albinism is a rare autosomal recessive disorder caused by congenital melanin deficiency, resulting in hypopigmentation of the eyes, hair, and skin. This study included a Chinese family with an oculocutaneous albinism pedigree, in which the proband presented with oculocutaneous albinismcombined with secondary angle closure, which has been rarely reported in previous literature. This article primarily focused on the clinical and genetic examination results of this patient and provided recommendations for ophthalmologist to treat patients with oculocutaneous albinism in clinical practice.
