BILATERAL SUBCUTANEOUS EMPHYSEMA FROM PRESSURIZED INFUSION DURING PARS PLANA VITRECTOMY: A CASE REPORT

Purpose: Presumed venous air embolism (PVAE) is a rare and potentially fatal complication of pars plana vitrectomy that is poorly described and understood but requires improved awareness among ophthalmologists and vitreoretinal surgeons. Methods: A case report is presented along with a systematic review of published reports of PVAE during ocular surgery. Results: An otherwise healthy adult male undergoing retinal detachment repair under local anesthesia with monitored anesthesia care died from a PVAE. Literature search yielded 2 experimental models, 6 individual case reports, and several editorials. Review of existing reports reveals that PVAE can affect patients of any age or gender with no medical predilection and occurs in cases of trauma, endoresection, or retinal detachment repair. It is typically associated with a drop in end-tidal carbon dioxide during fluid–air exchange and can present similar to a hemorrhagic choroidal detachment. Analysis suggests that venous air embolism can be prevented by ensuring full engagement of the infusion cannula into the vitreous cavity prior to fluid–air exchange. Conclusion: Presumed venous air embolism is a potentially fatal complication of ocular surgery and in some cases may be recognized by ophthalmologists as a choroidal detachment during fluid–air exchange in pars plana vitrectomy. It is imperative to immediately stop the air infusion line if venous air embolism is suspected.

Purpose. Tube exposure can lead to vision-threatening consequences and requires prompt surgical attention. Posterior repositioning of the tube to the pars plana has previously been reported as a successful technique. However, this method requires a pars plana vitrectomy (PPV). Here, we describe a novel technique of repositioning the tube into the ciliary sulcus without requiring PPV. Methods. This is a retrospective interventional case report of two patients who had undergone prior glaucoma drainage device implantation and prior tube exposure repair and developed recurrent tube exposure. Tube exposure in the subjects was repaired by repositioning the tube in the ciliary sulcus. Results. The two eyes remained exposure free postoperatively with 51- and 60-month follow-ups. Conclusions. Repositioning the tube to the ciliary sulcus may be an effective technique to avoid reexposure.

The exact pathogenesis of macular hole (MH) is controversial with most of the cases being idiopathic. Trauma is an important cause of secondary MH formation. MH post Pars Plana Vitrectomy (PPV) is an even rare entity with only a handful of cases reported so far ( Kumagai et al, 2008; Smiddy W.E, 1993; Kimura et al, 2005). An even rarer event is spontaneous closure of post PPV full thickness macular hole (FTMH), though spontaneous closure of traumatic macular hole (TMH) has been reported before. Herein, we report a 26 year old male patient who developed FTMH post PPV that closed spontaneously.

Purpose: To report and describe the clinical course of a pediatric traumatic macular hole (TMH) case and its management. Case Report: A pediatric patient presented a macular hole following blunt ocular trauma. The patient was followed every 2 weeks for 4 months. After the worsening of the macular hole reported by optical coherence tomography (OCT), pars plana vitrectomy with inverted flap technique plus SF6 gas tamponade was performed. Traumatic macular hole appeared closed at the OCT during follow-up. Initial visual acuity was counting finger at 30 cm. After surgery, the patient achieved a visual acuity of 20/100 at 3-month follow-up. Conclusion: This case shows a good anatomic and functional success performing a pars plana vitrectomy with inverted flap technique in a large TMH in a pediatric patient. We underline the importance of the surgical timing in the management of similar cases.

Purpose: This case report discusses the management of a patient with a superior chorioretinal coloboma-associated retinal detachment (RD), including surgical management, along with a review of the literature. Methods: A case report is presented. Results: A 58-year-old man presented with a chronic RD of the right eye that was symptomatic for approximately 1 year prior to presentation. On examination, he was found to have a macula-off RD associated with superior chorioretinal coloboma. He underwent 23-gauge pars plana vitrectomy with membrane peel, endolaser, and perfluoropropane (14%) gas tamponade. Three months after his surgery, his best-corrected visual acuity in his right eye was 20/250 distance and 20/80 near, and his retina remained attached. Conclusions: This case report describes surgical management of a superior chorioretinal coloboma-associated RD.
