“…Extraocular migration of emulsified SiO has been reported to occur in the subconjunctival space [ 1 ], [ 2 ], [ 3 ], [ 4 ], [ 5 ], [ 6 ], suprachoroidal space [ 7 ], eyelid [ 8 ], orbit [ 9 ], and brain [ 10 ]. Various factors have been implicated in causing the SiO to enter the subconjunctival space following VR surgery.…”

“…Subconjunctival leakage of silicone oil (SiO) is a known complication following vitreoretinal (VR) surgery. While it may be clinically visible on biomicroscopic examination in around 2.7% of cases [ 1 ], histopathological evidence has shown it to be present in as high as 33% [ 2 ]. In most situations, the leakage is minimal and does not pose many problems.…”

“…However, extensive leakage can lead to subconjunctival nodules, scarring in episcleral connective tissues, silicone oil underfill, and ultimately discomfort to patients [ 2 ]. Few reports have described the occurrence [ 1 ], [ 2 ], risk factors [ 3 ], [ 4 ], and management of subconjunctival SiO [ 5 ], [ 6 ]. We describe a case in which the presence of 360º subconjunctival SiO made a routine strabismus surgery for sensory exotropia difficult.…”

“…Intraocular SO migration into the subconjunctival space through a glaucoma tube shunt or through unsutured sclerotomies has been previously reported [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. In this particular case, a sutureless PPV and a pars plana tube GDD coexist, so the question is: Where did the subconjunctival SO come from?…”

Purpose: To report a case in which an early, massive silicone oil migration into the subconjunctival space occurred in a patient after sutureless vitrectomy with the presence of a previously implanted pars plana glaucoma drainage device. Case Report: An 80-year-old man presented with neovascular glaucoma secondary to a proliferative diabetic retinopathy in his left eye. After an intracamerular bevacizumab injection and panretinal photocoagulation, a 23-gauge pars plana vitrectomy (PPV) combined with a superotemporal Ahmed pars plana glaucoma valve implantation was performed. Afterwards, the patient underwent a new 23-gauge PPV for a dense vitreous hemorrhage. Intravitreal 1,000 centistokes silicone oil was placed to prevent recurrent intraocular bleeding. No sutures were performed. In the first postoperative month, a massive migration of silicone oil into the 360° subconjunctival space was noted until no intraocular silicone oil was observed. Conclusions: We discuss the possible leakage mechanisms in this particular case.

“… 5 , 6 Some histological studies have confirmed the presence of subconjunctival silicone oil in upto 30% of cases that cannot be detected on routine slit lamp biomicroscopy. 7 Another case series showed that 8-10% patients may have subconjunctival silicone oil bubble after undergoing sutures less 23G vitrectomy. 8 , 9 In the light of these observations, it has been generally recommended not to leave 23G sclerotomy sites without sutures when silicone oil is used as a tamponading agent.…”

Objective:To compare effectiveness of releasable transconjunctival sutures in 23 gauge vitrectomy and standard 20 gauge vitrectomy.Methods:This prospective comparative study was conducted in Department of Vitreoretinal Surgery, Al Ehsan Eye Hospital, Lahore from June 2016 to March 2017. It included 84 patients in total (Group-A: 42 patients underwent 23 gauge releasable suture vitrectomy; Group-B: 42 patients who underwent standard 20 gauge vitrectomy). Pre operative and post operative best corrected visual acuity, surgical duration, pre and post operative intraocular pressure and complication profile was compared between two groups.Results:The leading cause for vitrectomy was vitreous haemorrhage. (Group-A; n=15 ;35.71%; Group-B; n=17; 40.47%). There was statistically significant improvement in preoperative and postoperative BCVA in both groups (Group A: P-value < 0.05; Group B P-value < 0.05) but there was no significant difference in post operative BCVA between two groups at 3 months (P-value > 0.05). Surgical time for 23G vitrectomy Group was statistically less than 20 G vitrectomy Group (51 +/-18 minutes for Group-A versus 78 +/- 13 minutes for Group-B; p-value < 0.05). Visual analog score for pain / discomfort was also significantly less for Group-A than Group-B. There was no significant difference in intraocular pressures between the two groups.Conclusions:Releasable suture technique for small gauge vitrectomy is a safe and easily adaptable technique that has certain significant advantages over 20G absorbable suture vitrectomy.
