Acute angle-closure glaucoma in a case each of cicatricial retinopathy of prematurity and persistent hyperplastic primary vitreous

Purpose: To report acute angle-closure glaucoma in an eye with cicatricial retinopathy of prematurity and in another with persistent hyperplastic primary vitreous (PHPV). Cases: One was a 28-year-old female with PHPV in both eyes. Her right eye developed acute angle-closure glaucoma with intraocular pressure (IOP) of 48 mmHg. The chamber angle was closed in all the circumference. Lens extraction resulted in increased anterior chamber depth with decreased IOP. The other case was a 20-year-old male with cicatricial retinopathy of prematurity. He had received peripheral iridectomy in the right eye due to elevated IOP at the age of 14. IOP in the right eye rose to 34 mmHg after anterior dislocation of the lens. Lens extraction induced increased anterior chamber depth with decreased IOP. Conclusion: These cases illustrate that lens extraction may be effective for pupillary block after laser iridotomy or peripheral iridectomy has failed.
