Ultrasound biomicroscopy as a guideline for management of secondary iris cysts: a case series study

Abstract

Purpose The aim of this study was to evaluate the role of ultrasound biomicroscopy (UBM) in diagnosis, decision of intervention, and follow-up monitoring of secondary iris cysts. Patients and methods This case series study included 17 patients diagnosed clinically of having secondary iris cysts. History and full ophthalmological examination included visual acuity testing and slit lamp examination. UBM and B-scan ultrasound were performed for all cases. The study cases were divided into two groups according to the management plan (surgical management group and follow-up group). The follow-up period was 1 year. Results The study included 17 cases with unilateral secondary iris cysts. They were five females and 12 males, with age range from 3.0 to 44 years and a mean of 9.01±10.76 years. The clinical presentations such as blurring of vision, uveitis, red eye, ocular pain, or disfiguring intraocular swelling were insignificantly related to the different management groups (P>0.05). Angle closure and corneal touch (detected by UBM) were significantly present in the surgically managed cases, with P values of 0.003 and 0.009, respectively. The cyst size dimensions and its relation to the visual axis were detected with an insignificant difference between both groups. Conclusion UBM had a great value in the diagnosis of secondary iris cysts. Certain UBM findings were very important in deciding the different management plans and follow-up monitoring.
