Background. With the advances in surgical tools, simultaneous removal of cataract associated with vitreoretinal disorders is gaining popularity. This combined surgery offers several advantages besides limitations. The aim of this study is to assess the outcome and complications of phacoemulsification combined with pars plana vitrectomy (PPV). Patients and Methods. In this retrospective review, medical charts of patients undergoing phacovitrectomy for coexisting cataract and various vitreoretinal disorders were analyzed. Patient demographics, retinal diagnosis, visual acuities (VA) in logMAR, intraocular pressure (IOP), intraoperative and postoperative complications were assessed. Clear corneal phacoemulsification and 23-gauge transconjunctival PPV were administered in all cases. Results. Eighty-four eyes of 64 (76.2%) males and 20 (23.8%) females were enrolled. The average age of patients was 59.5 ± 13.8 (18–81). The average period of follow-up was 7.2 ± 7.5 months (1–36). The vitreoretinal diagnoses were as follows: 28 (33.3%) rhegmatogenous retinal detachment, 23 (27.4%) vitreous hemorrhage, 12 (14.3%) intraocular foreign body, 12 (14.3%) epiretinal membrane, 4 (4.8%) macular hole, 4 (4.8%) tractional retinal detachment, and 1 (1.2%) vitreomacular traction. The most common intraoperative complications were miosis and rupture of the posterior capsule (92.9% and 8.3%, respectively). In 8 (9.5%) cases, there was fibrin in the anterior chamber. Posterior synechia developed in 7 (8.3%) of cases. No severe increase in intraocular pressure was evident. Conclusion. Phacoemulsification combined with PPV is a safe and efficient way of management in cases where cataract coexists with vitreoretinal pathologies.

Purpose: Choroidal coloboma (CC) eyes are associated with a high risk of retinal detachment (RD), which are challenging to repair. Methods: We retrospectively evaluated medical records of 30 patients with CC associated with RD who underwent pars plana vitrectomy at our tertiary care center. Data recorded were age, CC and RD morphology, breaks, resurgeries performed, and final outcome. Results: Patients’ ages ranged from 2 to 49 years. CC was present in 53 of 60 eyes (88%), with 41 of 60 eyes (68.3%) associated with iris coloboma. RD was present in 36 of 53 CC eyes (67.9%), with 10 of 53 (18.9%) having bilateral RD. Thirty-one eyes with RD underwent 23-gauge pars plana vitrectomy. Colobomatous region breaks were detected in 5 of 31 eyes (16.1%), peripheral breaks only in 12 of 31 (38.7%), and both types in 3 of 31 eyes (9.7%). Silicone oil endotamponade was used in 29 of 31 eyes (93.5%) and perfluoropropane (C3F8) in 2 of 31 eyes (6.45%). Median postoperative follow-up duration was 31.5 months. Fourteen of 31 eyes (45.2%) developed redetachment requiring resurgery, with 50% developing within 6 months. Eighteen of 31 eyes (58.1%) maintained retinal attachment at last follow-up without endotamponade, whereas the rest were oil filled. Final visual outcome between macula-involved and macula-spared CC eyes was not significantly different; however, best visual acuity achieved any time during follow-up was significantly better in macula-spared eyes. Conclusions: RD surgery in CC eyes has a risk of frequent redetachments and subnormal gain of vision over the long term, especially in colobomas involving the macula. Endolaser in 360° peripheries in addition to barrage of the margin of the coloboma may be considered to help maintain the attached retina.

Introduction: Postoperative eccentric macular hole (MH) formation is an uncommon complication after pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling for epiretinal membrane or MH treatment. Herein, we present a case of eccentric MH formation after PPV with ILM peeling for MH. Case Description: A 72-year-old female patient underwent 23-gauge PPV with ILM peeling for idiopathic MH in her right eye. The visual acuity was 6/24 in the right eye. One week postoperatively the retina was attached and the MH seemed to be closed, while visual acuity was 6/12. One month after PPV, there was a single eccentric retinal hole below the macula, which was detected at the fundoscopy and was confirmed by OCT. The visual acuity was 6/9 and the patient referred no symptoms. No further intervention was attempted, and at the 6-month follow-up the visual acuity and the size of the eccentric MH remained stable. Conclusions: Eccentric MHs can develop after PPV and are usually managed conservatively by observation.

Purpose: The purpose of this study was to compare rates of clinically significant complications between 23- and 25-gauge pars plana vitrectomy (PPV) in vitreoretinal surgery. Methods: Demographics, PPV indication, and surgical complications were reviewed. Patients with prior PPV or other retina surgery; cases requiring silicone oil removal, keratoplasty, or glaucoma valve implant; patients <18 years old; or patients with <4 months of follow-up were excluded. Comparative and descriptive statistics were used to evaluate the data. Results: A total of 579 eyes met inclusion criteria, and their charts were reviewed. Demographics, PPV indication, follow-up time, and lens status were similar ( P > .05). A 23-gauge PPV was performed more frequently than a 25-gauge PPV (328 vs 251 eyes, respectively). Although rates of eyes with a clinically significant postoperative complication requiring surgical intervention were higher in 23-gauge PPV (112/325, 34.4%) than in 25-gauge PPV (54/250, 21.6%), PPVs indicated by rhegmatogenous retinal detachment were more common with 23-gauge PPVs (155/325, 47.7%) than with 25-gauge PPVs (37/250, 14.8%; P <.001) and were more likely to have postoperative complications; however, rates of recurrent retinal detachments were not different in the 2 cohorts ( P = .862). When controlling for differences in indication, there was a moderately higher rate of postoperative complications following 23-gauge PPV ( P = .063). Conclusions: This retrospective review suggests that clinically significant complications are moderately more likely following 23-gauge PPV compared with 25-gauge PPV, even when the differences in surgical indication are considered.

Aim: To study the treatment outcomes and efficacy of pars plana vitrectomy-hyaloidotomy-zonulectomy-iridotomy in malignant glaucoma. Method: A retrospective case series study of patients treated for malignant glaucoma between 2005 and 2017. The treatment included medical management as first-line in the form of cycloplegic with anti-glaucoma medications (AGM) or pars plana vitrectomy-hyaloidotomy-zonulectomy-iridotomy as second-line therapy. The resolution was defined as ‘deepening of central anterior chamber’ with intraocular pressure of ⩽ 21 mm Hg (minimum on two consecutive visits 1 week apart) with or without topical anti-glaucoma medications in the absence (complete success) or presence (qualified success) of systemic medications. Results: Twenty-three eyes of 22 patients were included. At the time of diagnosis of malignant glaucoma preceding surgeries were cataract surgery (13 eyes) and trabeculectomy (4 eyes). One eye each had phacotrabeculectomy, Yag capsulotomy and optical keratoplasty. Eighteen eyes were pseudophakic and two eyes were phakic. At presentation, mean intraocular pressure was 26.25 ± 14.78 mmHg which was decreased to 15.90 ± 8.12 mmHg (p < 0.0001) at final follow-up (median follow-up was 15.50 months). Fifteen (75%) eyes had complete success, 3 (15%) eyes had qualified success and 2 (10%) eyes had treatment failure. Of 15 eyes that had achieved complete success, 3 eyes had undergone medical management and 12 eyes undergone second-line procedure. There was no significant difference in visual acuity or number of anti-glaucoma medication at presentation and final follow-up (p > 0.05). Conclusions: Though malignant glaucoma is highly refractory to treatment, appropriate management in the form of medical or vitrectomy-hyaloidotomy-zonulectomy-iridotomy could achieve 90% success in this series.

Ex Vivo Study

PurposeTo assess whether pars plana vitrectomy (PPV) is an aerosol-generating procedure (AGP) in an ex vivo experimental model.MethodsIn this ex vivo study on 10 porcine eyes, optical particle counter was used to measure particles ≤10 μm using cumulative mode in the six in-built channels: 0.3 μm, 0.5 μm, 1 μm, 2.5 μm, 5 μm and 10 μm aerosols during PPV. Two parts of the study were as follows: (1) to assess the pre-experimental baseline aerosol count in the theatre environment where there are dynamic changes in temperature and humidity and (2) to measure aerosol generation with 23-gauge and 25-gauge set-up. For each porcine eye, five measurements were taken for each consecutive step in the experiment including pre-PPV, during PPV, fluid–air exchange (FAX) and venting using a flute with 23-gauge set-up and a chimney with 25-gauge set-up. Therefore, a total of 200 measurements were recorded.ResultsWith 23-gauge and 25-gauge PPV, there was no significant difference in aerosol generation in all six channels comparing pre-PPV versus PPV or pre-PPV versus FAX. Venting using flute with 23-gauge PPV showed significant reduction of aerosol ≤1 μm. Air venting using chimney with 25-gauge set-up showed no significant difference in aerosol of ≤1 μm. For cumulative aerosol counts of all particles measuring ≤5 μm, compared with pre-PPV, PPV or FAX, flute venting in 23-gauge set-up showed significant reduction unlike the same comparison for chimney venting in 25-gauge set-up.ConclusionPPV and its associate steps do not generate aerosols ≤10 μm with 23-gauge and 25-gauge set-ups.
