| | Case History | | A 61-year-old man with advanced open angle glaucoma and visually significant cataracts underwent combined cataract extraction, intraocular lens implantation, and Ahmed valve placement in the left eye. Six weeks later, the patient was evaluated in the clinic for a routine follow-up. The slit-lamp exam and anterior segment optical coherence tomography done at that time are shown below. | | | Questions | 1. What condition does this patient have?
2. How did the patient develop this condition, and what is its clinical significance?
3. At which point during glaucoma or cataract surgery can the Descemet's membrane be torn or stripped?
4. How could you manage the Descemet’s tear intraoperatively in order to avoid further stripping of the membrane?
5. What should you do when closing the incision, and why?
6. What other modalities can you consider for fairly large Descemet’s detachments?
7. How does gas treat a Descemet’s detachment? | | | [View Answers] |
