Purpose Pseudophakic glaucoma is a form of secondary glaucoma characterized by elevated intraocular pressure following cataract extraction and intraocular lens (IOL) implantation, in the absence of preexisting glaucoma. This study aims to evaluate the effectiveness of ultrasound biomicroscopy (UBM) in visualizing anterior segment structures and identifying etiopathogenic factors contributing to pseudophakic glaucoma. Patients and methods This prospective, observational case series study included 51 eyes of 51 patients diagnosed with postoperative pseudophakic glaucoma. All patients underwent complete ophthalmologic examination and UBM analysis, along with thorough medical history documentation. Results Many possible causes of pseudophakic glaucoma have been demonstrated through UBM examination. These causes were intraocular inflammation, IOL-related causes, and lens remnants. Fifteen eyes had haptic-related causes, eight eyes had tilted or decentered IOLs, peripheral anterior synechia were found in 12 eyes while eight eyes were reported with posterior synechia, neovascular glaucoma was evident in two eyes, in three eyes Soemmering ring was detected, and three eyes with lens particles in anterior chamber. Conclusion Pseudophakic glaucoma can be evaluated by using the UBM, which has a great role in detecting the changes that occurred in the anterior segment of the eye.
