Introduction Optic capture of sutured scleral fixated posterior chamber intraocular lenses (PC IOLs) is an occasional complication resulting in blurred vision and discomfort. Methods A retrospective study of the management of 18 eyes (3.6%) with optic capture out of 495 eyes with scleral fixated IOLs during the study period. 54 procedures were performed in the management of optic capture of sutured scleral fixated PC IOLs. An in-office technique was utilized to relieve the optic capture by repositioning the optic posterior to the iris. This technique was performed after topical anesthesia and topical 5% betadine with the patient stably positioned at the slit lamp. Using a 30-gauge needle, sometimes after a 15-degree paracentesis blade, the needle was advanced in a parallel plane above the iris until the tip reached the edge of the captured optic. The optic is engaged in the inferior periphery away from the central visual axis, and pushed gently posteriorly just enough to reposition the optic posterior to the iris. In some cases, pilocarpine 2% drops were utilized after the procedure to decrease the risk of recapture of the optic. Results All 54 procedures were successfully performed in the office without significant pain or discomfort. Vision before optic capture, during optic capture, and at the first office visit after optic capture were comparable. There were not any cases of endophthalmitis, hyphema, iris trauma, iris prolapse or keratitis. While eight patients only had one episode of optic capture, 10 patients had multiple episodes of optic capture, all managed with this in office procedure. Recurrent optic capture occurred more frequently in eyes with fixation at less than 2 mm from the limbus than eyes with scleral fixation at 2 mm from the limbus. Conclusion Reposition of the optic after pupillary capture of a scleral fixated PC IOL can be successfully performed in the office without discomfort or significant complications and is an alternative management option to a return to the operating room. This procedure may be especially important when there is poor access to the operating room or restricted access to the operating room as during the COVID19 pandemic.
Purpose: To describe a case of successful resolution of severe hypotony and choroidal detachments following nonfiltering glaucoma surgery with an intravitreal injection of C3F8 gas after a poor response to topical steroids and cycloplegia. Methods: Retrospective chart review of a case report. Results: 89 year-old male presented with a central retinal vein occlusion, hyphema, vitreous hemorrhage and neovascular glaucoma. After initial intravitreal injection of aflibercept he was treated with pars plana vitrectomy with panretinal photocoagulation and endocyclophotocoagulation to the ciliary body, but he continued to have elevated intraocular pressure. Subsequent external cyclophotocoagulation was performed but severe hypotony with inflammation, choroidal detachments, and corneal edema developed one week later without response to cycloplegic and steroid medications. A therapeutic injection of perfluorpropane (C3F8) gas led to resolution of the hypotony and choroid detachment and long-term maintenance of intraocular pressure. Discussion/Conclusion: An intravitreal gas bubble can be a very useful outpatient procedure to immediately reverse hypotony, resolve choroidal detachment, and decrease associated inflammation. When hypotony does not respond to medical therapy with cycloplegic drops and steroid medications, then an intravitreal gas bubble can rapidly resolve these complications and result in stabilization of intraocular pressure long-term.
