Descemet’s membrane detachment (DMD) is a rare but serious complication of phacoemulsification surgery. A small DMD may resolve spontaneously, but extensive DMD often requires intracameral injection of air, nonexpansile gases, or expansile gases. A 92-year-old man who underwent phacoemulsification and aspiration with intraocular lens placement in the right eye had significantly reduced visual acuity, with a hazy cornea after surgery. Anterior segment optical coherence tomography (AS-OCT) examination revealed extensive DMD throughout the cornea. He was treated with intracameral injection of 20% sulfur hexafluoride. As a result, the Descemet membrane was successfully reattached, and the corneal edema resolved. AS-OCT was helpful in confirming the presence and extent of DMD, provided useful information to determine the appropriate treatment, and was useful for monitoring DMD.

Background: Postoperative descemet’s membrane detachments (DMD) can be vision threatening if not detected early and managed appropriately Eyes with DMD usually have corneal haze which may hamper slitlamp evaluation. Anterior segment optical coherence tomography (ASOCT) is a precise, non-invasive imaging technique that yields high resolution cross sectional images of the cornea. This study aims to evaluate the usefulness of AS OCT as compared to slitlamp biomicroscopy in the detection and management of post-operative DMD following small incision cataract surgery.Methods: It was a prospective study on sixty-seven patients who underwent cataract surgery. Slitlamp biomicroscopy and ASOCT were done in all patients on postoperative day one. The presence of descemet’s membrane detachment was noted using each technique. Eyes with DMD were followed up one week and again one month later. ASOCT was repeated to assess the status of DMD. Management was planned accordinglyResults: On post-operative day one, only 1.49% of the study group showed descemet’s detachment on slitlamp biomicroscopy, as against 20.89% using ASOCT. This increase in diagnostic yield on ASOCT was statistically significant(p=0.05). On follow-up, descemet’s membrane had reattached in seven eyes one week after surgery and in all eyes one month after surgery, with medical management alone.Conclusions: AS OCT has a definite advantage over slit lamp biomicroscopy in the detection of descemet’s membrane detachment following cataract surgery. Our study also validates the fact that AS OCT helps in follow up and decision making in the management of DMD.

Background: To present an intraoperative acute Descemet’s fold formation using swept-source optical coherence tomography (SS-OCT) imaging. Case Report: A 67-year-old man complaining of reduced visual acuity in the left eye. A 25-gauge pars plana vitrectomy combined with phacoemulsification cataract surgery was performed to remove the vitreomacular traction. When hydro-sealing was performed, striae rapidly spread in the cornea. SS-OCT B-scan images performed on postoperative day 1 revealed a wavy Descemet’s membrane that might correspond to Descemet’s folds. Pairs of hypo- and hyperreflective narrow lesions running from the wavy Descemet’s membrane to almost half of the thickness of the whole cornea were observed. En face OCT imaging clearly showed the stromal fold, which continuously spread from the Descemet’s fold. Conclusion: The stromal fold might be due to the focal bulge of the stroma posteriorly caused by the rapid volume increase of the stroma which could push Descemet’s membrane posteriorly, thereby forming a wavy Descemet’s membrane layer.

Anatomic Locations

Iris pigment epithelial (IPE) cysts are a subset of iris cysts that arise from the IPE. They are spontaneously erupting epithelial-lined cavities that are found in various anatomic locations of the iris, including the iris pupillary margin, midzone, periphery, and free floating in the vitreous or anterior chamber. We report the case of an asymptomatic 13-year-old boy with an incidental finding of a dislodged anterior chamber cyst diagnosed on routine examination. Modern multimodal image analysis of the cyst including anterior segment optical coherence tomography and ultrasound biomicroscopy (UBM) was utilized to characterize the microstructural anatomy of the lesion. The patient was managed conservatively without complications. Cysts of the IPE typically do not affect vision or ocular health and can be monitored and observed after ascertaining no associated malignancy. Initial diagnostic investigation can include UBM and anterior segment optical coherence tomography. Intervention should be reserved only for cases where the cyst growth leads to obstruction of the visual axis and/or other secondary complications.
