Simultaneous injection-aspiration technique of air/fluid exchange for in-office treatment of post-operative vitreous cavity hemorrhage.

ABSTRACT:

Background

Post-operative vitreous cavity hemorrhage following pars plana vitrectomy is common. In-office drainage of the hemorrhage may be an option for some patients.

Technique

A new method for office-based air fluid exchange is described. A 30-gauge needle with a 10-mm syringe filled with sterile air is inserted 3.5-mm posterior to the limbus in the superotemporal quadrant. A second 30-gauge needle is inserted 3.5 mm from the limbus at 6 o'clock and connected to an empty 10-mm syringe with intravenous catheter tubing. The plunger of the air-filled syringe is pushed while the plunger of the empty syringe is pulled, so that the rate of fluid aspiration matches the rate of air injection.

Discussion

The method approximates conditions in pars plana vitrectomy, with balanced infusion and aspiration. Displaced vitreous cavity contents are collected in the aspiration syringe. The procedure is also cost effective.

Conclusion

The simultaneous syringe method is an easy, safe, and effective way of clearing post-operative vitreous cavity hemorrhage.

Project description:BackgroundTo compare efficacy and safety of intravitreal aflibercept (IVA) injection with panretinal photocoagulation (PRP) versus early vitrectomy for diabetic vitreous hemorrhage (VH).MethodsProspective, randomized study that included 34 eyes with diabetic VH. They were divided into two groups, Group Ι (17 eyes) received three successive IVA injections followed by PRP and group ΙΙ (17 eyes) for whom early vitrectomy was done. Follow up was carried out after one, two, three, six and nine months. The primary outcome measure was change in the mean best corrected visual acuity (BCVA) after nine months, secondary outcome measures were mean duration of clearance of VH and rate of recurrent hemorrhage with any additional treatment in both groups. Complications were reported.ResultsThere was no statistically significant difference regarding initial demographic criteria between both groups. The mean final log MAR BCVA was statistically better than the initial BCVA in both groups (0.51 ± 0.20, 1.17 ± 0.48 for group I and 0.48 ± 0.18, 1.44 ± 0.44 for group II, P < 0.001). There was no statistically significant difference between both groups regarding the mean final Log Mar BCVA (0.51 ± 0.20 for group I, 0.48 ± 0.18 for group II, p ≥ 0.05), the mean duration of clearance of VH was 7.8 ± 1.8 weeks, 5 days for group I and II respectively. PRP was completely done for all eyes in group I after three months. The difference in the recurrence rate between group I (29.4%) and group II (11.8%) was statistically significant (p < 0.05). Vitrectomy was done for three eyes (17.6%) due to recurrent non-resolving VH in group I. late recurrent VH occurred in two eyes (11.8%) in group II, IVA was given with complete clearance of the hemorrhage. No vision threatening complications were reported in both groups.ConclusionBoth intravitreal injection of aflibercept followed by PRP and early vitrectomy are effective and safe modalities for treatment of diabetic vitreous hemorrhage. Early vitrectomy leads to faster vision gain with less incidence of recurrence than intravitreal injection.Trial registrationRandomized clinical trial under the number of NCT04153253 on November 6, 2019 "Retrospectively registered".

Project description:BackgroundThe authors report a case of a rare complication that occurred after botulinum toxin injection to the extraocular muscle, which was easily overlooked and successfully corrected by surgery.Case presentationA 34-year-old female patient visited our clinic for diplopia and ocular motility disorder after removal of an epidermoid tumor of the brain. At her initial visit, her best-corrected visual acuity (BCVA) was 20/20 for both eyes. An alternate cover test showed 45 prism-diopter esotropia and 3 prism-diopter hypertropia in the right eye. Following 6 months of observation, the deviation of the strabismus did not improve, and botulinum toxin was injected into the right medial rectus (RMR). After 6 days, she visited our clinic with decreased visual acuity of her right eye. The BCVA was found to be 20/50 for her right eye. Funduscopic examination presented a retinal tear inferonasal to the optic disc with preretinal hemorrhage. Subretinal fluid nasal to the fovea was seen on optical coherence tomography (OCT). Barrier laser photocoagulation was done around the retinal tear; however, her visual acuity continued to decrease, and vitreous hemorrhage and subretinal fluid at the lesion did not improve. In addition, a newly developed epiretinal membrane was seen on OCT. An alternate cover test presented 30 prism-diopter right esotropia. 19 weeks after RMR botulinum toxin injection, she received pars plana vitrectomy, membranectomy, endolaser barrier photocoagulation, and intravitreal bevacizumab (Avastin®) injection. After 4 months, her visual acuity improved to 20/20, and only 4 prism-diopter of right hypertropia and 3 prism-diopter of exotropia were noted. Vitreous opacity and the epiretinal membrane were completely removed, as confirmed by funduscopic and examination.ConclusionsSudden loss of vision after injection of botulinum toxin into the extraocular muscle may suggest a serious complication, and a prompt, thorough ophthalmic examination should be performed. If improvements are not observed, rapid surgical intervention is recommended to prevent additional complications.
