Clinical and histopathological features of posttraumatic iris cyst

Abstract

Iris cyst excision involves complex surgical maneuvers and may have a variable visual outcome depending upon preexisting and postoperative complications. Hereby, we report a case series of 10 eyes from which posttraumatic iris cysts were excised and proven histopathologically. Histopathology records were reviewed. Data regarding patient profile, clinical profile, surgical details, treatment outcomes and follow-up were reviewed. Outcome measures were defined as recurrences, visual acuity and number of other surgeries required. Non-parametric Wilcoxon test was used to compare changes in the visual acuity and Fisher test was used to find out the significance of several risk factors. Mean age was 24.7 years (3-58 years). Mean follow- up was 2.36 years. Mean preoperative logMAR visual acuity was 0.56 in comparison to final logMAR visual acuity of 1.62. Factors related to adverse functional outcome were related to post-surgical complications.

Long-term follow-up and visual outcome after excision of a traumatic iris cyst by viscoelastic dissection

“…The follow-up of our case is considerably longer than previous studies reporting iris lesions. For example, mean follow-up was 2.36 years in one study [6] and up to 3 years in another [1].…”

Delayed Treatment of Secondary Iris Cyst due to Blunt Ocular Trauma

“…The irregular curvature of iris cyst and thin wall has led to the diagnosis of an iris epithelial cyst [11]. It has been shown that the results of imaging with AS-OCT examination are as good as the results of ultrasound biomicroscopy (UBM) examination [12].…”

“…The iris cyst develops either from a break in the epithelium or iris stroma; aqueous humor then enters through this port de entrée and creates a space in between where the cyst will grow, eventually reaching the corneal endothelium and resulting in corneal edema [2][3][4][5]. Various surgical procedures for iris cysts have been reported and the result depends on the size of the cyst, the affected area of camera oculi anterior and prompt treatment [6][7][8][9].…”

Surgical Management of Post-Traumatic Iris Cyst

“…The challenge in the surgical management of an iris cyst is to identify the complete extent of the epithelial down growth, and to ensure the removal of the cyst in toto [ 5 ]. If the cyst is ruptured, or part of the cyst wall or associated epithelial downgrowth is left behind, there is a high chance of recurrence.…”

“…These cells in the anterior chamber then grow into a sheet or form a cyst [ 4 ]. Traumatic iris cysts are of two types: the “solid-looking” cyst or pearl cyst has stratified or cubical epithelium lining the cyst wall; the second type is, called the serous cyst, contains straw colored turbid fluid [ 5 ].…”
