23-Gauge Transconjunctival Sutureless Vitrectomy: Visual Outcomes and Complications

Purpose: To report results and complications of 23-gauge transconjunctival sutureless pars plana vitrectomy for a variety of vitreoretinal diseases.

Methods: A prospective consecutive case series study was performed in 66 eyes of 66 patients. Indications for surgery were epiretinal membrane (n?=?20), rhegmatogenous retinal detachment (n?=?19: 14 pseudophakic, 5 phakic), macular hole (n?=?16), vitreous hemorrhage (n?=?5), cyclodialysis (n?=?1), intraocular lens luxation (n?=?1), asteroid hyalosis (n?=?1), congenital retinoschisis (n?=?1), and endophtalmitis (n?=?2). Main outcome measures included visual acuity, intraocular pressure, and intra- and post-operative complications.

Results: Mean patient age at time of operation was 68?±?12 years. Overall, visual acuity improved from 1.03?±?1.00 logMAR preoperatively to 0.32?±?0.33 logMAR postoperatively (p?<?0.01) after a mean follow-up time of 9.3?±?4.7 months. Mean preoperative intraocular pressure was 13.9?±?3.5 mmHg, and mean postoperative intraocular pressure was 17.9?±?9.6 mmHg on day 1 (p?<?0.01) and 14.7?±?2.8 mmHg (p?=?0.05) at final visit. Concerning complications, 2 cases of hypotony and 7 of hypertony occurred on day 1, a macular hole reopened some weeks later, and a retinal detachment recurred in one case.

Conclusion: 23-gauge transconjunctival sutureless vitrectomy is an effective and safe technique for a variety of vitreoretinal diseases.     

The incidence and distribution of iatrogenic retinal tears in 20-gauge and 23-gauge vitrectomy

Purpose

The development of 23-gauge vitrectomy surgery has many benefits including a reduction in surgical time and faster postoperative rehabilitation; however, some have suggested that the complication rate is higher. To assess this we compared the incidence and distribution of iatrogenic retinal tears in 20- and 23-gauge surgery.

Methods

Fifty consecutive 23-gauge and 50 consecutive 20-gauge vitrectomy cases were selected; eyes with a history of previous vitreoretinal surgery were excluded. All surgery was performed by two surgeons (JL and RN). Entry-site breaks (ESB) were defined as any new vitreoretinal abnormality occurring within 1 clock hour of an entry site for which treatment with cryotherapy was deemed necessary. Data were collected by retrospective case note review. Statistical analysis was carried out using Fisher''s exact and χ²-tests.

Results

ESB occurred in 24% (12/50) of cases in the 20-gauge group compared with 8% (4/50) in the 23-gauge group (P=0.03); 88% (14/16) occurred superiorly on the same side as the surgeons'' dominant hand. Iatrogenic breaks recorded elsewhere indicated an increased incidence in the 20-gauge group (9/50 compared with 6/50 in 23-gauge) but this did not achieve significance; the most common position was at 6 o''clock.

Conclusions

23-Gauge vitrectomy is associated with significantly fewer ESB when compared with conventional 20-gauge vitrectomy. The incidence of other iatrogenic breaks did not appear to be significantly different between the two groups.

Comparison of postoperative intraocular pressure changes between 23-gauge transconjunctival sutureless vitrectomy and conventional 20-gauge vitrectomy

Purpose

To compare the intraocular pressure (IOP) after 23-gauge transconjunctival sutureless vitrectomy (TSV) and conventional 20-gauge vitrectomy for various vitreoretinal diseases.

Methods

This was a retrospective interventional case series including 338 cases of 23-gauge TSV and 476 cases of 20-gauge vitrectomy with minimum follow-up period of 1 month. Postoperative 1 day, 1 week and 1 month IOPs were compared. Multiple regression analysis to assess the actual effect of gauge of vitrectomy on postoperative IOP was performed including intraoperative and postoperative factors influencing postoperative IOP as covariates.

Results

The mean IOP of 20-gauge vitrectomy was significantly higher than that of 23-gauge TSV (20.6±8.02 mm Hg vs12.8±4.48 mm Hg, P<0.001) at postoperative day 1, but the differences were not significant at postoperative 1 week and 1 month. The IOP pattern of 23-gauge TSV demonstrated more stable course than that of 20-gauge vitrectomy. At 1 day post vitrectomy, the incidence of hypertony was higher in 20-gauge, whereas that of hypotony was higher in 23-gauge. Among risk factors, the 20-gauge vitrectomy showed the strongest association with postoperative 1 day IOP rise.

Conclusion

Twenty-three-gauge TSV has stable and lower IOP in the early postoperative period than the 20-gauge vitrectomy. In patients whose retina and optic nerves are vulnerable to higher or fluctuating IOP, 23-gauge TSV may be more beneficial.     

No-patch 23-gauge vitrectomy under topical anesthesia: a pilot study

A pilot study was designed to evaluate the safety and efficacy of 23-gauge vitrectomy under topical anesthesia. Five eyes of five patients underwent 23-gauge sutureless vitrectomy under topical anesthesia with a pledget soaked in 0.5% proparacaine hydrochloride anesthetic, for vitreous hemorrhage (four eyes), epiretinal membrane (one eye). Subjective pain and discomfort were graded using a visual analogue chart from 0 (no pain or discomfort) to 4 (severe pain and discomfort). At the end of surgery no patch was applied and patients were given dark glasses. Patients underwent an immediate postoperative assessment, followed by next day and one week postoperative evaluation. Four patients had Grade 0 pain during the surgery. One patient had Grade 1 pain during the placement and withdrawal of the micro cannulas. The surgical outcomes were favorable. 23-gauge vitrectomy under topical anesthesia is safe and effective in selected cases. Further study is recommended to validate the outcome of this study.     

Combination 20 and 23-gauge transconjunctival vitrectomy: A new approach

The advent of smaller gauge instrumentation allows for minimally invasive vitreoretinal surgery (MIVS) as compared to conventional pars plana vitrectomy. Sutureless posterior segment surgery has the advantages of faster wound healing, minimal surgical trauma, decreased convalescence period besides reduced postoperative astigmatism; however, slower gel removal and limited peripheral vitreous dissection are disadvantages with smaller gauge systems. We herein describe a new technique combining 23-gauge and 20-gauge vitrectomy to improve the effectiveness and outcomes of vitreoretinal surgery.

Posterior capsule opacification following 20- and 23-gauge phacovitrectomy (posterior capsule opacification following phacovitrectomy)

Purpose

To compare the development of posterior capsule opacification (PCO) for idiopathic epi-retinal membrane cases between 20- and 23-gauge phacovitrectomy.

Methods

Cataract surgery of phacoemulsification with the SA60AT implantation and 20- or 23-gauge vitrectomy was performed for 20 patients in both groups. Cataract surgery alone was performed for 50 patients as the control. The PCO density values were measured using Scheimpflug video photography at 1 week, 1, 3, 6, 12, 18, and 24 months after surgery. The number of eyes that required Nd:YAG laser capsulotomy was also examined.

Results

The mean PCO value in the 20-gauge phacovitrectomy group increased significantly with time (P<0.001), whereas those in the 23-gauge phacovitrectomy group and the cataract surgery group did not show any significant change. Furthermore, the PCO value in the 20-gauge phacovitrectomy group was significantly greater than that in the 23-gauge phacovitrectomy group at 6, 12, 18 (P<0.05), and 24 months (P<0.01) after surgery. The PCO value in the 23-gauge phacovitrectomy group was significantly greater than that in the cataract surgery group 24 months after surgery (P<0.05). The rate of capsulotomy in the 20-gauge phacovitrectomy group was significantly higher than that in the cataract surgery group (P=0.007), whereas there was no significant difference between the 23-gauge phacovitrectomy group and the cataract surgery group.

Conclusion

PCO rate in eyes with the 23-gauge phacovitrectomy was lower than in those with the 20-gauge phacovitrectomy, and PCO rate even in the 23-gauge phacovitrectomy was higher than in those with cataract surgery.     

Primary 23-gauge vitreoretinal surgery for rhegmatogenous retinal detachment

AIM: To report the effectiveness and safety of primary 23-Gauge (G) vitreoretinal surgery for rhegmatogenous retinal detachment (RRD). METHODS: In this retrospective study, 49 eyes of 49 consecutive patients who underwent primary 23-G transconjunctival sutureless vitrectomy (TSV) for RRD between January 2007 and July 2009 at our institution were evaluated. RESULTS: Mean follow-up time was 8.9±7.7 months (1-28 months). Retinal reattachment was achieved with a single operation in 47(95.9%) of 49 eyes. In two eyes (4.1%), retinal redetachment due to new breaks was successfully treated with reoperation using the 23-G TSV system. Mean logMAR visual acuity was 2.01±0.47 preoperatively and 1.3±0.5 postoperatively (P<0.001, Paired t-test). Mean preoperative intraocular pressure (IOP) was 14.1±2.8mmHg. Mean postoperative IOP was 12.3±3.6mmHg at 1 day, 13.1±2.1mmHg at 1 week, 14.3±2.2mmHg at 1 month. Iatrogenic peripheral retinal break was observed in 1 eye (2.0%) intraoperatively. No sutures were required to close the scleral or conjunctival openings, and no eyes required convertion of surgery to 20-G vitrectomy. CONCLUSION: Primary 23-G TSV system was observed to be effective and safe in the treatment of RRD.

Outcomes of Primary Transconjunctival 23-Gauge Vitrectomy in the Diagnosis and Treatment of Presumed Endogenous Fungal Endophthalmitis

Purpose: To report the outcomes of primary transconjunctival 23-gauge (23-G) vitrectomy in the diagnosis and treatment of presumed endogenous fungal endophthalmitis (EFE).

Methods: Retrospective analysis of patients with EFE who underwent diagnostic transconjunctival 23-G vitrectomy at a tertiary referral center.

Results: Nineteen eyes of 15 patients with EFE were included in the study. Four patients had bilateral and 11 patients unilateral disease. Sixteen eyes of 15 patients underwent 23-G vitrectomy to confirm the diagnosis using vitreous culture, polymerase chain reaction, and histopathologic examinations. All affected eyes were treated with intravitreal amphotericin B 5 µg/0.1 mL. Fourteen patients received additional systemic antifungal therapy. Diagnostic 23-G vitrectomy confirmed the diagnosis of EFE in 75% of the eyes (12/16). Candida was found to be a causative agent in 62.5% and Aspergillus in 12.5% of the eyes. Retinal detachment was the most common complication (42% of eyes).

Conclusions: EFE can be easily confirmed using primary 23-G vitrectomy.     

Ahmed valve implantation for neovascular glaucoma after 23-gauge vitrectomy in eyes with proliferative diabetic retinopathy

AIM:To report on the outcome of Ahmed glaucoma valve (AGV) implantation for the management of neovascular glaucoma (NVG) after 23-gauge vitrectomy for proliferative diabetic retinopathy (PDR).METHODS: Twelve medically uncontrolled NVG with earlier 23-gauge vitrectomy for PDR underwent AGV implantation. The control of intraocular pressure (IOP), preoperative and postoperative best-corrected visual acuity, the development of intraoperative and postoperative complications were evaluated during the follow-up.RESULTS: The mean follow-up was 15.4±4.3 months (9-23 months). Mean preoperative IOP was 49.4±5.1mmHg and mean postoperative IOP at the last visit was 17.5±1.6mmHg. The control of IOP was achieved at the final follow-up visits in all patients, however, 8 of 12 patients still needed anti-glaucoma medication (mean number of medications, 0.8±0.7). The visual acuity improved in nine eyes, and the visual acuity unchanged in three eyes at the final follow-up visits. The complications that occurred were minor hyphema in three eyes, choroid detachment in two eyes, and the minor hyphema and choroid detachments were reabsorbed without any surgical intervention.CONCLUSION: AGV implantation is a safe and effective procedure that enables successful IOP control and vision preservation in the NVG patients with the history of earlier 23-gauge vitrectomy for PDR.     

Closed Vitrectomy in the Management of Diabetic Traction Retinal Detachment

One hundred and seventy-four instances of diabetic traction retinal detachment in which the patient underwent closed vitrectomy during the period of January 1970 to December 1978 and had adequate follow-up ranging from six months to five years are reported. As a rule, eyes with vision better than 20/200, or with inaccurate light projection, or with no response to electrophysiologic tests were excluded. The surgical technique avoided stripping of vitreous membranes. Closed vitrectomy was combined with scleral buckling in eyes with retinal breaks, and with scleral resection in eyes with incomplete section of traction membranes. Anatomic improvement was noted in 75.3% of the eyes; vision improved in 64.9% of the eyes; new or recurrent vitreous hemorrhage was observed in 43.1%; corneal decompensation in 51.8%, rubeosis iridis in 23.0%, phthisis bulbi in 9.2%, iatrogenic retinal break in 8.6%, postoperative rhegmatogenous retinal detachment in 5.2%, and iatrogenic cataract in 4.6%.     

Clinical presentation of a mixed 23-gauge infusion and 20-gauge pars plana technique for active silicone oil removal

AIM: To present with a clinical case series of a mixed 23-gauge infusion and 20-gauge pars plana technique for 5,700-centipoise silicone oil removal (SOR), and to discuss its efficacy and safety.METHODS: This is a retrospective, non-randomized controlled study. We performed SOR with 23-gauge infusion and 20-gauge active suction technique on 29 patients 29 eyes from April to October, 2011 (mixed group). During the surgeries, a 23-gauge sclerotomy was made for infusion and a 20-gauge sclerotomy was used for active silicone oil suction. Anterior segment optical coherence tomography (OCT) was applied for 23-gauge sclerotomy analysis 1 day post-operation. Traditional 20-gauge SOR was performed on another consecutive 29 patients 29 eyes, the control group (20G group).RESULTS: There were 2 eyes (6.9%) in mixed group and 5 eyes (17.2%) in 20G group which had recurrent retinal detachment after surgery. Hopytony (IOP≤6mmHg) occurred in 8 eyes (27.6%) of mixed group and in 10 eyes (34.5%) of 20G group post-operation, but all of them recovered to the normal level finally. There were no statistical significant differences. Final visual acuity was significantly increased after surgery in both groups. Anterior segment OCT images were acquired from 13 eyes of mixed group, and all of them had a proper wound apposition. But local ciliary detachment was found in 9 eyes (69%). It was hard to define the OCT image of the sclerotomies and ciliary body because of the serious conjunctival hemorrhages and chemosis in 20G group.CONCLUSION: This mixed technique is a convenient and effective way to remove high viscosity silicone oil. Compared with traditional 20-gauge SOR, it does not increase the risk of post-operative complications and has less conjunctival reactions.. Transient postoperative hypotony is common for this procedure and subclinical ciliochoroidal detachment is a probable cause.     

25-gauge transconjunctival diagnostic vitrectomy in suspected cases of intraocular lymphoma:a case series and review of the literature

AIM: To report the cytology results of 25-gauge transconjunctival (25G-TSV) diagnostic vitrectomy in cases suspicious for intraocular lymphoma (IOL), and compare the results to those reported in the literature.METHODS: Clinical and cytopathological records of 18 vitreous biopsy specimens obtained via 25G-TSV diagnostic vitrectomy in 12 patients suspicious for IOL were reviewed retrospectively. A review of the literature in regards to the diagnostic yields of vitreous specimens obtained via 25-gauge and 20-gauge diagnostic vitrectomy in suspected cases of IOL was performed.RESULTS: Eighteen eyes from 12 patients with clinical suspicion of IOL underwent diagnostic 25G-TSV. The cytopathological investigations demonstrated IOL in 15 eyes (83.3%). Vitreous analysis was non-diagnostic in 3 eyes (16.7%).CONCLUSION: Twenty-five-gauge diagnostic vitrectomy yields adequate sample for cytological evaluation of the vitreous in cases suspicious for IOL. The diagnostic results of the 25G-TSV in the current study are superior to those reported for 20-gauge vitrectomy but equivalent to those reported for 25G-TSV in the published literature.
