The index case involves a 5-year-old twin brother, who, during a routine examination, exhibited elevated intraocular pressure persisting for over a month. The peak intraocular pressure reached approximately 25 mmHg (1 mmHg=0.133 kPa) in both eyes, with a corneal diameter of less than 10 mm. Ocular examination revealed an enlarged cup-to-disc ratio, and optical coherence tomography (OCT) demonstrated thinning of the retinal nerve fiber layer and ganglion cell layer. Ultrasound biomicroscopy combined with gonioscopy indicated partial angle closure and abnormal anterior chamber angle development. The ocular manifestations in the twin brother were consistent with those observed in the twin sister. The clinical diagnosis was bilateral developmental glaucoma with microcornea. Genetic sequencing identified two novel compound heterozygous mutations in the ADAMTS18 gene in the twins: Mutation 1 (M1) involving the variant site 1 (c.3436C>T:p.R1146W) and Mutation 2 (M2) involving the variant site 2 (c.1454T>G:p.F485C). Ocular examinations of four additional family members were normal. Genetic testing revealed that the twins' father and sister carried M1, while the index case's mother and brother carried M2.

A modification was made by combining total convergence amplitude using synoptophore and distance angle at distance using prism bars to calculate total convergence amplitude/distance angle. Exotropia control at distance and near measured by Office-based Scale for Assessing Control was classified as good control (scale 0-1) and poor control (scale 2-5). Statistical analysis was performed using Spearman correlation analysis, Mann-Whitney <i>U</i> test, Fisher's exact test, <i>χ</i>² test, logistic regression analysis, and mediation effect analysis. <b>Results:</b> The study included 212 patients, of which 105 (49.5%) were male and 107 (50.5%) were female. The median (interquartile range) age was 9.0 (8.0, 10.0) years. Of 211 cases, 201 (94.8%) had binocular fusional function, while 11 cases (5.2%) did not have binocular fusional function. Among patients with binocular fusional function, inverse correlation was observed between total convergence amplitude and exotropia control scores for both distance (<i>r</i>=-0.427, <i>P</i><0.001) and near (<i>r</i>=-0.194, <i>P</i>=0.006).
