Abstract
Rationale:The presence of cholesterol crystals in the anterior chamber is extremely rare, and secondary glaucoma with cholesterol crystals in the anterior chamber, reported in the literature, is even rarer. This paper reports 3 cases of secondary glaucoma with cholesterol crystals in the anterior chamber.Patient concerns:Three patients were admitted to the hospital because of ocular distension and blindness. Ocular examination on admission indicated high intraocular pressure, and crystalline gold substances were observed in the anterior chamber.Diagnosis:Based on clinical manifestations and an aqueous fluid smear, absolute glaucoma and anterior chamber cholesterol crystals were diagnosed.Interventions:In the first case, transscleral ciliary photocoagulation was performed; in the last 2 cases, trabeculectomy combined with extracapsular cataract extraction was performed.Outcomes:The follow-up period was 11 to 15 months. Intraocular pressure was stable in 2 patients treated with surgery, and no cholesterol crystals were observed in the anterior chamber. The intraocular pressure increased in 1 patient treated with laser, and a small amount of cholesterol crystals was still observed in the anterior chamber.Lessons:Anterior chamber cholesterol crystallization is extremely rare and cannot be treated if it does not cause other lesions. However, glaucoma occurred in all 3 cases in this study, and intraocular pressure increased in 1 case after laser treatment and remained stable in 2 cases after surgical treatment. Therefore, the treatment plan for anterior chamber cholesterol crystallization in glaucoma requires further discussion.
