Objective: To demonstrate the clinical characteristics and surgical effects of glaucoma in Hallermann-Streiff syndrome(HSS). Methods: Observational case series and literature review. The results of ophthalmic examinations of three patients diagnosed as glaucoma with HSS were recorded, including visual acuity, intraocular pressure (IOP), slit-lamp microscopy, ultrasound biomicroscopy, optical coherence tomography, corneal topography, A-scan and B-scan ultrasonography, and orbital size measurement by X-ray. Peripheral iridectomy, glaucoma drainage device implantation or trabeculectomy, were performed in these patients. Results: Three HSS patients were 9, 29 and 47 years old, respectively, including 2 females and 1 male. The best corrected visual acuity was 0.04-0.5. The mean spherical equivalent refraction was +12.1 D. The average IOP was 37.7 mm Hg, and the average corneal diameter was 9.1 mm. The average central anterior chamber depth was 2.43mm. The average axial length was 18.13mm. Keratometry showed average K1 of 56.97 degrees, and K2 of 60.65 degrees. Two younger patients were aphakic bilaterally with uveitis, pupillary fibrous membrane and peripapillary choroidal atrophy. The older patient showed blue sclera, cataract, and anterior chamber angle closure. The horizontal orbital diameter was 28.76-31.40 mm, and vertical orbital diameter was 30.16-32.90 mm. All patients were proportionate nanism, with an average height of 143 cm. Craniofacial manifestations included dyscephalia and “bird-like” face, hypotrichosis, dental anomalies, and mandibular hypoplasia. They were followed up for an average of 47.7 months(range:11-84 months) after surgery. The IOPs were all controlled, and the visual acuities remained unchanged. No treatment-related complications occurred. Conclusions: HSS patients with glaucoma may present as small orbit, microphthalmia, microcornea, blue sclera, aphakia, pupillary fibrous membrane, uveitis, with atrophic chorioretinal changes. For these patients, personalized treatment may help to achieve better therapeutic effects.
