RESUMEN

OBJECTIVE: The aim of this study is to elucidate the factors contributing to the occurrence of retinal detachment (RD) following prophylactic vitrectomy in cases of acute retinal necrosis (ARN) syndrome. METHODS: A retrospective examination was undertaken, encompassing the medical records of patients diagnosed with ARN who underwent prophylactic vitreous intervention at the Ophthalmology Department of Wuhan University Renmin Hospital East Campus between October 2019 and September 2023. Subsequently, patients who manifested RD in the postoperative period were identified, and a comprehensive analysis was conducted to ascertain the factors underlying the occurrence of RD post-surgery. RESULTS: This study comprised 14 cases (involving 14 eyes) of patients diagnosed with ARN who underwent prophylactic vitreous intervention. The findings revealed that 4 patients experienced postoperative RD, resulting in an incidence rate of 28.57%. Notably, among these cases, 3 cases of RD manifested in the presence of silicone oil, while 1 case occurred subsequent to the removal of silicone oil. All 4 cases of RD exhibited varied degrees of proliferative vitreoretinopathy. Following the occurrence of RD, all patients underwent a secondary vitreous intervention coupled with silicone oil tamponade, leading to successful reattachment of the retina. However, despite these interventions, there was no significant enhancement observed in postoperative visual outcomes when compared to preoperative levels. CONCLUSION: RD following prophylactic vitrectomy in cases of ARN is not an infrequent occurrence and is primarily linked to the postoperative onset of proliferative vitreoretinopathy.

RESUMEN

BACKGROUND: To compare the effects of a 3D head-up system and microscope eyepiece-assisted simulated vitrectomy intraocular illumination on the ocular surface of an operator. METHODS: This was a prospective randomized controlled study. According to the application system, thirty ophthalmic operators (60 eyes) were randomly divided into 3D and eyepiece groups. Under different intensities of intraocular illumination, operators in both groups viewed the fundus model through a 3D display screen or microscopic eyepiece for 2 h. Objective examinations and a subjective symptom questionnaire were used immediately after the test to evaluate the ocular surface of the operators. Objective examinations included nonintrusion tear meniscus height (NIKTMH), nonintrusion break-up time (NIKBUT), and bulbar redness and strip meniscometry tube (SMTube) measurements. Statistical analyses were performed by using SPSS 26.0 software. RESULTS: After the test, the NIKTMH, NIKBUT and SMTube measurements decreased; however, the degree of change varied among the groups of different systems. The differences between the 3D group and the eyepiece group in NIKTMH measurements, SMTube measurements, subjective symptom scores (eye dryness, difficulty focusing, and cervical pain), and light intensity reaching the ocular surface of the operators were statistically significant (P < 0.05). All of the objective and subjective tests showed that the 3D group had fewer effects on the NIKTMH and SMTube measurements, and the subjective comfort of the 3D group was greater. CONCLUSION: For both 3D screens and eyepieces, simulated vitrectomy with intraocular illumination for two hours can lead to discomfort and abnormalities in the operator's ocular surface; however, these abnormalities are less severe in the 3D group. TRIAL REGISTRATION: This trial was registered on December 22, 2022, at the Chinese Clinical Trials Registry with NO. ChiCTR2200066989.

RESUMEN

PURPOSE: To evaluate the importance of the status of posterior vitreous in eyes with endophthalmitis following intravitreal anti-vascular endothelial growth factor (anti-VEGF). METHODS: The absence or existence of posterior vitreous detachment (PVD) was elicited in 23 eyes of 23 patients with injection related endophthalmitis, during pars plana vitrectomy (PPV) and compared with 24 control eyes of 24 patients who received intravitreal anti-VEGF without any complication. RESULTS: Thirtten (54.2%) out of 24 patients in the control group had full PVD, whereas only 2 (9.5%) out of 23 eyes in endophthalmitis group (p < 0.001) had full PVD. In all eyes without PVD, posterior vitreous was inducted to be detached at least from optic nerve and macular area without any iatrogenic tear. CONCLUSION: The absence of PVD is a factor that increases the risk of endophthalmitis after intravitreal injections. Uncomplicated separation of the posterior vitreous from the retina in PPV contributes to better prognosis.

RESUMEN

BACKGROUND: Anterior vitrectomy is a skill all cataract surgeons should develop and master. Every surgeon will have complications at some point in his/her career. Complication management should be part of the surgical training for all cataract surgeons. Posterior capsular rent does not translate to poor visual outcomes. If managed properly, excellent visual outcomes can be achieved and complications minimized. We aim to simplify the anterior vitrectomy procedure by this video. PURPOSE: This video will serve as a step-by-step practical guide to the intraoperative management of posterior capsular rent by simplifying the anterior vitrectomy procedure. SYNOPSIS: This video will demonstrate how to tackle the dreaded complication of a posterior capsular rent with vitreous disturbance, and achieve optimal postoperative outcomes. HIGHLIGHTS: We demonstrate how a PCR appears, and once identified, how to proceed. In addition, nuances regarding foot positions and different vitrectomy modes are included. Biaxial vitrectomy is explained. Lens placement post-PCR is demonstrated. Furthermore, a brief about postoperative management is included. VIDEO LINK: https://youtu.be/dTo7sMpe8h8.

RESUMEN

BACKGROUND: Submacular hemorrhage (SMH) is a sight-threatening disorder. Choroidal neovascularization secondary to age-related macular degeneration, polypoidal choroidal vasculopathy, trauma, angioid streaks, and pathological myopia are a few important causes. The conventional treatment of massive SMH is vitrectomy with manual removal of the clot with extensive retinectomy with/without tissue plasminogen activator (tPA). The usual dose of subretinal tPA is 10-25 µg. PURPOSE: To describe a new surgical approach in a case of massive SMH with retinal detachment without retinectomy. SYNOPSIS: In our case of near total hemorrhagic retinal detachment due to subretinal hemorrhage caused by trauma (road traffic accident), the patient presented with a visual acuity of counting fingers. Core vitrectomy was performed and posterior vitreous detachment was induced. The locations for retinotomy to inject and aspirate subretinal blood were selected at the maximum height of retinal elevation near the arcades. Recombinant tPA (10 µg/0.1 ml concentration; 0.3 ml injected in two locations) was injected subretinally with a 23-G soft tip cannula in the superotemporal and inferonasal quadrant causing subretinal bleb formation. Subsequently, the surgeon waited for approximately 20 min on the table for the liquefaction of the clot. The liquefied blood and tPA were drained with a silicone soft tip. Endolaser was performed at the retinotomy site and 1000cs silicone oil was injected. No signs of toxicity such as vitritis, vasculitis, or retinal necrosis were noted. HIGHLIGHTS: Our unique technique of high-dose intraoperative subretinal tPA (60 µg) is safe and helpful in rapid clot lysis and recovery of visual acuity. The patient gained a visual acuity of 20/80 from counting fingers after 1 month of surgery and 20/60 after silicone oil removal. A high dose of tPA aids in the immediate aspiration of blood from a small retinotomy. A 23-G soft tip was used instead of a 41-G subretinal cannula to inject a large quantity of subretinal tPA.

RESUMEN

Purpose: This study aimed to develop artificial intelligence models for predicting postoperative functional outcomes in patients with rhegmatogenous retinal detachment (RRD). Methods: A retrospective review and data extraction were conducted on 184 patients diagnosed with RRD who underwent pars plana vitrectomy (PPV) and gas tamponade. The primary outcome was the best-corrected visual acuity (BCVA) at three months after the surgery. Those with a BCVA of less than 6/18 Snellen acuity were classified into a vision impairment group. A deep learning model was developed using presurgical predictors, including ultra-widefield fundus images, structural optical coherence tomography (OCT) images of the macular region, age, gender, and preoperative BCVA. A fusion method was used to capture the interaction between different modalities during model construction. Results: Among the participants, 74 (40%) still had vision impairment after the treatment. There were significant differences in age, gender, presurgical BCVA, intraocular pressure, macular detachment, and extension of retinal detachment between the vision impairment and vision non-impairment groups. The multimodal fusion model achieved a mean area under the curve (AUC) of 0.91, with a mean accuracy of 0.86, sensitivity of 0.94, and specificity of 0.80. Heatmaps revealed that the macular involvement was the most active area, as observed in both the OCT and ultra-widefield images. Conclusions: This pilot study demonstrates that artificial intelligence techniques can achieve a high AUC for predicting functional outcomes after RRD surgery, even with a small sample size. Machine learning methods identified The macular region as the most active region. Translational Relevance: Multimodal fusion models have the potential to assist clinicians in predicting postoperative visual outcomes prior to undergoing PPV.

RESUMEN

BACKGROUND: The main purpose of this paper is to introduce a method that can accurately locate the posterior capsule of the lens to facilitate a relatively complete resection of the anterior vitreous body. METHODS: A total of 51 patients in the experimental group and control group were enrolled in this study. Phacoemulsification combined with vitrectomy was performed in all cases. After the cataract procedure was completed in the control group, the surgeon performed a conventional anterior vitrectomy with the operative eye. In the experimental group, anterior vitrectomy was performed according to the threadiness corrugation of the posterior capsule of the lens. During the operation, with the help of triamcinolone, two surgeons confirmed the resection of the anterior vitreous cortex; the best corrected visual acuity and intraocular pressure of all patients were recorded at 1 week, 1 month and 3 months after surgery. RESULTS: Fifty patients underwent phacoemulsification combined with vitrectomy, except one patient in the experimental group who was lost to follow-up. After surgery, no significant complications were observed in all patients except two patients in the control group with temporary increases in intraocular pressure. There was no significant difference in preoperative visual acuity between the two groups (t = 0.83, P = 0.25). Both groups had varying degrees of improvement in best corrected visual acuity at 1 week, 1 month and 3 months after surgery. Moreover, there was no significant difference in BCVA between the two groups at the three follow-up time points (t=-1.15, -1.65, -1.09, P = 0.53, 0.21, 0.23). After surgery, no significant complications were observed in all patients except two patients in the control group with temporary increases in intraocular pressure. Incomplete resection of the anterior vitreous cortex was observed in 2 patients in each group, but there was no significant difference (χ2 = 7.81, P > 0.05). CONCLUSION: In the process of cataract surgery combined with vitrectomy, thready corrugation appears in the posterior capsule of the lens and is an important sign of its localization. Anterior vitrectomy can be accomplished safely and effectively with the help of thread-like corrugation, and the surgical effect is almost the same as that of traditional surgery. Especially suitable for beginners in vitreous surgery.

RESUMEN

A female in her 20s presented with a diminution of vision in the right eye (RE) following an open globe injury (scleral penetration) and repair a year back. At the presentation, she had low intraocular pressure (IOP) of 7 mm Hg, posterior subcapsular cataract (PSC), retrolental vitreous bands incarcerated at the penetration site, disc oedema, tortuous vessels and choroidal folds. Inferotemporal and superonasal cyclodialysis clefts were detected on CASIA 2 optical coherence tomography (OCT). The diagnosis of RE repaired scleral penetration, PSC and cyclodialysis cleft with hypotony maculopathy was made. The case was managed by phacoemulsification with an intraocular lens in the bag and a capsular tension ring in the sulcus, as a tamponading agent to close the cleft. Intraoperatively on endoscopic visualisation, vitreous membrane was noticed encasing the ciliary processes causing a tractional cyclodialysis and hence single port 23G pars plana vitrectomy was performed to relieve the traction. Postsurgery, IOP was 14 mm Hg, and the repaired cleft was visualised on anterior segment OCT.

RESUMEN

PURPOSE: This study sought to compare the long-term outcomes of surgeries for retinal detachment (RD) secondary to viral or parasitic infectious retinitis. METHODS: A total of 47 eyes that received pars plana vitrectomy with or without scleral buckling due to RD secondary to polymerase chain reaction-proven viral (cytomegalovirus, varicella zoster virus, and herpes zoster virus) or parasitic (toxoplasma and toxocara) retinitis from October 1, 2006, to June 30, 2023, in a single medical center were retrospectively enrolled. RESULTS: Mean follow-up period was 59.03 ± 55.24 months in viral retinitis and 34.80 ± 33.78 months in parasitic retinitis after primary reattachment surgery. During follow-up, nine eyes (24.3%) with viral retinitis and five eyes (50.0%) with parasitic retinitis developed retinal redetachment. Visual acuity success at final follow-up was achieved in 19 eyes (51.4%) with viral retinitis and six eyes (60.0%) with parasitic retinitis (p = 0.64). The incidence of retinal redetachment during the 1st postoperative year was significantly higher in parasitic retinitis compared with viral retinitis (crude incidence, 0.21 vs. 0.85; p = 0.02). Hazard ratio analysis adjusted for age and sex showed 4.58-fold (95% confidence interval, 1.22-17.27; p = 0.03) increased risk of retinal redetachment in parasitic retinitis compared with viral retinitis during the 1st postoperative year. Tamponade with silicone oil and preoperative diagnostic vitrectomy were associated with significantly decreased risk of retinal redetachment in patients with parasitic retinitis. CONCLUSIONS: Compared with RD secondary to viral retinitis, RD secondary to parasitic retinitis showed higher incidence of retinal redetachment during the 1st postoperative year. Tamponade with silicone oil and preoperative diagnostic vitrectomy were associated with significantly decreased risk of retinal redetachment in patients with parasitic retinitis.

RESUMEN

PURPOSE: Comparing between the visual outcomes and post operative complications of two surgical treatments for sub macular hemorrhage, pars plana vitrectomy with tissue plasminogen activator (tPA) injection procedure, and pneumatic displacement of submacular hemorrhage with intravitreal tPA injection. METHODS: A retrospective chart review of patients with sub macular hemorrhage (SMH) was performed. Data was collected from 150 patients with sub macular hemorrhage. Patients were followed up from the day of admission and up to a year post surgery. Evaluation included visual acuity, optical coherence tomography (OCT), fundus examination and rates of complications. RESULTS: Pars plana vitrectomy procedure has showed a better visual outcome in small SMH. Comparing complications between the two treatment modalities, no significant difference has been found in the study. CONCLUSIONS: Pars plana vitrectomy and tPA showed a clear advantage with a trend of better visual acuity as well as a significant predictor to better visual acuity for small and medium sub macular hemorrhage.

RESUMEN

PURPOSE: To evaluate the effect of adjuvant Mitomycin C (MMC) use on the anatomical and functional success of vitreoretinal surgery (VRS) in severe diabetic tractional retinal detachment (dTRD) patients. METHODS: A retrospective analysis of consecutive patients undergoing VRS due to severe dTRD was conducted. Patients were categorized into those who received 20 µg/0.1 mL MMC via MMC sandwich method (Group 1) and those who did not (Group 2). Demographics, surgical characteristics, visual outcomes, and complications that may related to MMC were analyzed. RESULTS: A total of 25 eyes were included, 13 in Group 1 and 12 in Group 2. No statistical difference was observed in baseline characteristics between the groups. The mean best-corrected visual acuity was 1.90 ± 0.43 logMAR and 1.93 ± 0.41 logMAR preoperatively and 1.60 ± 0.78 logMAR and 1.56 ± 0.78 logMAR postoperatively in Groups 1 and 2, respectively (p = 0.154). The postoperative mean intraocular pressure was 16.23 ± 2.55 mmHg and 13.08 ± 4.94 mmHg in Groups 1 and 2, respectively (p = 0.225). The rate of re-surgery was significantly lower in Group 1 (0% vs. 41.7% in Group 2, p = 0.015). Retina was attached in all patients at the last visit. No MMC-related complication was recorded. CONCLUSION: Intraoperative adjuvant MMC application for severe dTRD significantly reduces re-surgery rates with good anatomical and functional outcomes safely.

RESUMEN

The incidence of diabetic retinopathy (DR) requiring vitreorentinal surgery is increasing. The search for new effective and safe methods of treatment, the choice of the optimal time for surgery, and the assessment of long-term treatment outcomes are relevant problems. PURPOSE: This study evaluates the long-term results of vitreorentinal surgery using the bimanual technique in DR with different stages of fibrovascular proliferation. MATERIAL AND METHODS: The study included 135 patients (135 eyes) who were divided into groups depending on the predominant type of proliferation - vascular or fibrous. Patients underwent vitrectomy with membranectomy using the bimanual technique, with peripheral panretinal endolaser coagulation of the retina and tamponade of the vitreous cavity with balanced salt solution. The postoperative observation period lasted up to 12 months. RESULTS: Both groups showed statistically significant improvement in visual function and anatomical changes in central retinal thickness. A statistically significant improvement in best corrected visual acuity (BCVA) was found in patients with initially predominantly vascular proliferation. Correlation analysis showed that initially higher BCVA tends to persist in the postoperative period. A negative correlation was found between the final BCVA and the presence of type 2 diabetes mellitus, fibrous stage of proliferation, high central retinal thickness, and the presence of diabetic macular edema (DME) - both initially and after treatment. The frequency of complications in the groups was comparable, except for postoperative DME, which was more often detected in patients with fibrous proliferation. CONCLUSION: The bimanual technique of vitreorentinal surgery for complications of DR allows achieving high anatomical and functional results. Higher BCVA is noted in patients with the vascular stage of proliferation and initially high BCVA. The obtained data allow us to form a hypothesis about the possibility of earlier surgery in patients with high BCVA, but require further investigation.

RESUMEN

RATIONALE: Acute retinal necrosis (ARN) was first reported in 1971 by Urayama et al as an acute uveitis accompanied by retinal arteritis and white retinal lesions in the peripheral retina that can progress to a rhegmatogenous retinal detachment (RRD). We have experienced a case of ARN that, unlike the common developmental course to an RRD associated with ARN, progressed to proliferative vitreoretinopathy (PVR) involving the entire retina in 2 days. The purpose of this report is to present our findings in the case of ARN with an atypical rapid time course. PATIENT CONCERNS: The patient was a 56-year-old woman who was treated for uveitis of unknown origin by her primary care physician. She was referred to our hospital because of a worsening of the fundus findings. DIAGNOSIS: Fundus examination in our hospital revealed vitreous opacities in the right eye, yellowish-white lesions extending around the retina, and some retinal hemorrhages. Because the retinal changes suggested ARN, we performed a polymerase chain reaction of the anterior atrial fluid and detected varicella-zoster virus. Then, the diagnosis of ARN was confirmed, and treatment was begun. At 1 month and a half after beginning the treatment, focal retinal traction was observed in the right fundus. Two days later, a circumferential PVR and a total retinal detachment were detected. INTERVENTIONS: We then performed vitrectomy with an encircling buckle and a silicone oil tamponade. OUTCOMES: Our examination 6 months postoperatively showed that the retina was attached and the BCVA was 20/200. LESSONS: Our findings of a case of ARN showed that the progression from a local vitreous traction to a full circumferential PVR can develop in 2 days.

RESUMEN

PURPOSE: To evaluate macular sensitivity using microperimetry in patients with proliferate diabetic retinopathy following vitrectomy and to investigate the relationship between the sensitivity and foveal microstructures with optical coherence tomography/angiography. METHODS: Eighty-four eyes of 84 patients with proliferative diabetic retinopathy, who were indicated for vitrectomy, had no intraocular surgery history 3 months preoperatively, and were able to ensure fundus examination after the vitrectomy, were included. A logMAR best-corrected visual acuity, macular sensitivity of microperimetry, macular retinal thickness, and macular vessel perfusion using optical coherence tomography/angiography were examined at 1 week, 1 month, and 3 months postoperatively. RESULTS: The logMAR best-corrected visual acuity and mean macular sensitivity of patients with proliferative diabetic retinopathy improved postoperatively (P < 0.05). There was a significant correlation between best-corrected visual acuity and mean sensitivity (P < 0.05). Postoperative mean macular sensitivity was significantly correlated with outer retinal thickness in the 0 to 6 mm macular area (P < 0.05) and also significantly correlated with deep capillary plexus perfusion (P < 0.05). Fixation stability and mean macular sensitivity did not show any correlation with glycated hemoglobin, triglyceride, serum total cholesterol, carbamide, and creatinine and duration of diabetes mellitus (P > 0.05). CONCLUSION: Postoperative mean macular sensitivity was significantly correlated with outer retinal thickness and deep capillary plexus perfusion for patients with proliferative diabetic retinopathy. The authors found that the visual performance of patients can be evaluated by the outer retinal thickness and deep capillary plexus perfusion, so optical coherence tomography/angiography examination can be an important prognostic factor for visual performance in patients.Clinical Trial Registration: This trial is registered with the Chinese Clinical Trial Registry (http://www.chictr.org.cn; Registration No.: ChiCTR2100043399).

To assess the efficacy and safety of topical insulin (TI) for treating neurotrophic keratopathy (NK) within one-month post-diabetic vitrectomy (DV) compared to conventional non-invasive measures, we conducted this retrospective case-control study including all eyes that developed acute NK (stages 2 and 3) following DV between October 2020 and June 2023. The control group included NK cases managed with preservative-free lubricant eye drops and prophylactic topical antibiotics. In contrast, the study group included NK cases treated with TI [1 unit per drop] four times daily, in addition to the previously mentioned treatment. The primary outcome measure was time to epithelial healing. Secondary outcome measures included any adverse effect of TI or the need for amniotic membrane transplantation (AMT). During the study period, 19 patients with a mean age of 49.3 ± 8.6 years received TI versus 18 controls with a mean age of 52.5 ± 10.7 years. Corneal epithelial healing was significantly faster in the TI-treated group compared to controls, with a mean difference of 12.16 days (95% CI 6.1-18.3, P = 0.001). Survival analysis indicated that the insulin-treated group had 0% and 20% of NK stages 2 and 3, respectively, that failed to achieve corneal epithelial healing, compared to 20% and 66.7% for the control group (P < 0.001). In the control group, two eyes required AMT due to progressive thinning. Additionally, three patients in the control group, progressing to stage 3 NK, were switched to TI, achieving healing after a mean of 14 days. No adverse effects were reported in the TI-treated group. Our study suggests that TI can effectively and safely promote the healing of NK after DV.

RESUMEN

We report the visual and clinical outcomes of a middle-aged woman who presented with exudative retinal detachment (ERD) secondary to a vasoproliferative tumor (VPT) in an eye with sarcoidosis-associated intermediate uveitis. A 55-year-old woman previously diagnosed with sarcoidosis presented with decreased vision in the left eye (LE). Visual acuity in the LE was counting fingers. She had active vitritis, and a peripheral retinal vascular mass was noted in the superotemporal periphery. The mass was associated with ERD involving the posterior pole. The patient was managed with systemic and intravitreal steroids, and cyclosporine was subsequently added as a steroid-sparing agent. Because of recurrence of ERD, the patient underwent pars plana vitrectomy, and cryotherapy and laser photocoagulation were applied to the VPT. Two months postoperatively, visual acuity in the LE improved to 6/10. There was marked regression of the VPT and total resolution of the ERD. In conclusion, we report a favorable visual and clinical outcome in a patient with VPT-associated ERD who responded to a combination of medical therapy and surgical intervention. VPT may lead to different remote complications, so timely diagnosis of these tumors and proper management of their complications is warranted.

RESUMEN

BACKGROUND: A 7-year-old male child was brought by his parents with a complaint of low vision in both eyes for 2 months. The child had low vision in both the eyes for 1.5 years, but the parents noticed when it worsened further 2 months back, leading to profound vision loss. On ophthalmic evaluation, the child did not perceive light in the right eye. Furthermore, anterior segment examination showed complicated cataract and open funnel retinal detachment with intra-retinal cysts in ultrasound (USG) B scan. In the left eye, he could appreciate light but with poor fixation. Fundus evaluation of the left eye showed total retinal detachment on indirect ophthalmoscopy, which was confirmed on USG B scan. Since the right eye had poor visual potential, no intervention was done. The left eye underwent pars plana vitrectomy with silicone oil tamponade, which led to successful anatomical outcomes. The immediate and late postoperative periods were uneventful, and the child was kept under follow-up and was observed closely. PURPOSE: To educate regarding the surgical management of giant retinal tears in a pediatric patient. SYNOPSIS: To inform regarding the surgical challenges faced and steps adopted to manage such cases. HIGHLIGHTS: Through this case, we want to highlight the challenges faced, such as delayed presentation, difficult preoperative evaluation, intraoperative difficulties such as mobile retina, absence of posterior vitreous detachment, and tenacious vitreous gel. We also want to emphasize on the steps taken to overcome the challenges. CONCLUSION: In such challenging situations, effective planning, careful manipulation, and persistence are essential for success. VIDEO LINK: https://youtu.be/T0Gy6Wj13zI.
