Unplanned Reoperation following Vitreoretinal Surgery. J Curr Ophthalmol 2023; 35:56-60. [PMID: 37680287 PMCID: PMC10481975 DOI: 10.4103/joco.joco_343_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 04/10/2023] [Accepted: 04/13/2023] [Indexed: 09/09/2023] Open
Abstract
Purpose To evaluate the incidence of unplanned return to the operating room following vitreoretinal surgery and assess the reasons. Methods In this retrospective case series, medical records of all patients who underwent vitreoretinal surgery were reviewed to determine the incidence and reasons of early (<30 days postoperatively) and late (≥30 days postoperatively) unplanned reoperations after the surgery. Results A total of 488 eyes of 468 patients with a mean age of 55.84 ± 18.23 years were included. Fourteen percent (68/488) of eyes required one or more unplanned reoperation following their primary surgery. These include 3.9% (19/488) for the early and 10.0% (49/488) for the late reoperation. The most common primary reason for baseline surgery was rhegmatogenous retinal detachment (RRD) without proliferative vitreoretinopathy (PVR, 38.2%), followed by RD with PVR (23.5%), and tractional RD (TRD, 19.1%). Unplanned reoperations were most common in RD with PVR (19.3%), RRD without PVR (17.2%), and TRD (14.4%). Overall, the most common reasons of the first unplanned reoperation were repeated RD with PVR (27.9%), repeated RD (19.1%), and the presence of silicone oil (SO) in the anterior chamber (AC) (10.3%). For early unplanned reoperations, SO in AC, postoperative endophthalmitis, and persistent hyphema were the most common causes. Repeated RD with PVR was the most prevalent cause of late unplanned reoperations (34.7%). In the multivariate analysis, preoperative best-corrected visual acuity (BCVA) was significantly lower in eyes with unplanned reoperation than in eyes without (P = 0.011). Conclusions Unplanned reoperation following vitreoretinal surgery is not very common, and occurs mostly in the setting of PVR, RRD, and TRD. Lower preoperative BCVA may indicate an increased chance of future unplanned reoperation(s).

[PMID: 36414851 DOI: 10.1007/s10792-022-02573-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Accepted: 11/12/2022] [Indexed: 11/23/2022]
Abstract
PURPOSE To describe the findings and new interpretation methods of retinal thickness maps in the setting of hydroxychloroquine (HCQ) therapy. METHODS A case series of 27 patients with a history of HCQ intake of more than 5 years and 21 normal subjects as the control group were studied. Patients were tested using swept-source optical coherence tomography (OCT). Custom-made 10 × 10 retinal thickness pixel maps of the 6 mm⨯6 mm area centered on the fovea were created for the full, inner, and outer retina of each eye and normal values obtained from the control group were used to calculate the statistical significance of each pixel and highlight suspicious pixels. A pixel was shown with light or dark gray color if its p value was ≤ 0.05 or ≤ 0.01, respectively. Cross-sectional OCT images and visual fields were examined as well and used to confirm the diagnosis of HCQ retinopathy. RESULTS The pixel outer retinal thickness maps appeared accurate in detecting lesions even in eyes with unremarkable full retina thickness maps. The size and location of atrophic retinal defects were shown on pixel maps. Outer retinal thickness maps were able in differentiating outer retinal thinning from inner retinal thinning as the hallmark of HCQ retinopathy. CONCLUSION Outer retinal thickness pixel maps can be used for the screening of HCQ retinopathy.

Abstract
PURPOSE To investigate the effect of intravitreal recombinant tissue plasminogen activator (rt-PA) injection before vitrectomy on surgical facility and outcome in diabetic tractional retinal detachments (TRD). METHODS Prospective, randomized, interventional clinical trial. A total of 38 eyes with diabetic TRD were candidates for vitrectomy. Patients were randomized 1:1 to receive intravitreal rt-PA, five to seven days before vitrectomy or no injection. Intraoperative surgical facility and anatomic success at month 3 after surgery were assessed. RESULTS Mean patient age was 54.2 ± 9.4 years. There was no statistically significant difference between rt-PA and no injection groups with regard to anatomic success (89% versus 95%, respectively, P = 0.547) and best corrected visual acuity at 3 months (2.0 versus 2.1 logMAR, respectively, P = 0.840). However, surgical facility score was statistically significantly lower in rt-PA injection group compared to no injection group (4.1 ± 1.7, 5.8 ± 2.0, respectively, P = 0.007). CONCLUSIONS Vitrectomy for TRD was easier after preoperative rt-PA injection, without affecting the anatomic and visual outcomes.

J Curr Ophthalmol 2020; 32:159-163. [PMID: 32671299 PMCID: PMC7337023 DOI: 10.4103/joco.joco_78_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2019] [Revised: 03/02/2020] [Accepted: 03/04/2020] [Indexed: 12/05/2022] Open
Abstract
Purpose: To determine the changes in serum levels of free vascular endothelial growth factor (VEGF), insulin-like growth factor-1 (IGF-1), and growth parameters in infants with retinopathy of prematurity (ROP) who received intravitreal injection of the bevacizumab (IVB). Methods: A prospective interventional case series study, including 10 infants with Type 1 ROP was conducted. Using the enzyme-linked immunosorbent assay, serum levels of VEGF and IGF-1 were measured before, 1 month and 2 months after treatment with IVB in both eyes. Growth parameters, including weight, length, and head circumference and their Fenton’s z-score, were also measured. Results: Serum VEGF levels were suppressed 1 month after IVB (P = 0.007) and then increased between 1 and 2 months (P = 0.064). Z-scores of all growth parameters except weight z-score decreased in the 1st and 2nd months. Conclusion: Serum VEGF levels showed a transient reduction after IVB which lasted at least 2 months. Growth velocity of premature infants may be affected by anti-VEGF therapy and should be followed with particular attention.

Abstract
Purpose: To evaluate the role of intrasilicone oil injection of methotrexate (MTX) at the end of vitrectomy surgery for rhegmatogenous retinal detachment (RRD) associated with proliferative vitreoretinopathy (PVR).Methods: In this prospective comparative study, pars plana vitrectomy and retinal reattachment were performed for eyes with RRD with grade C PVR. In the MTX group, 250 µg MTX was injected into the silicone oil at the end of surgery. The rate of retinal redetachment associated with PVR was assessed.Results: In total, 44 eyes of 44 patients (22 in the MTX group and 22 controls) were included. Baseline characteristics were similar between the two groups. Retinal redetachment occurred in one eye (4.5%) in the MTX group and five eyes (22.7%) in the control group (p = 0.18). The change in visual acuity was similar between the two groups at final visit (p = 0.15).Conclusion: The rate of redetachment associated with PVR was lower after intrasilicone injection of MTX at the end of vitrectomy for RRD with severe PVR compared to control group; however, the difference was not statistically significant.

Abstract
Objective: To evaluate the short-term changes in Schirmer I test (ST) after pars plana vitrectomy and to compare the results between 23 gauge and 20 gauge vitrectomy surgeries. Methods: 42 patients who underwent pars plana vitrectomy for posterior segment diseases were included in this prospective, non-randomized, comparative study. The choice of sclerotomy gauge was at the surgeons’ discretion. ST values were recorded before and at 1 and 3 months after vitrectomy. Results: 20 patients in 23 gauge and 22 patients in 20-gauge group with a mean age of 59.9 ± 13.5 years were included. The mean preoperative ST values decreased significantly in both groups at 1 and 3 months after surgery (all P < 0.01). The ST values in the fellow eyes were the same, at baseline and during the follow up (P > 0.05). At 3 months visit, 15 eyes (35.7%) had abnormal ST measurements. There was no statistically significant difference in the changes in the ST measurements between the two groups at one month (P = 0.7), however, 3 months after surgery, the mean decrease in the ST measurements was significantly higher in the 20 gauge group (P = 0.03). At 3 months, 4 eyes in the 23 gauge group (20%) and 11 eyes in the 20 gauge group (50%) had abnormal ST measurements (P = 0.05). Conclusions: Although both 20 and 23-gauge vitrectomy decrease the ST measurements postoperatively, the value is less affected by the 23-gauge vitrectomy.

Abstract
PURPOSE To provide the clinical recommendations for the administration of intravitreal anti-vascular endothelial growth factor (VEGF) drugs especially bavacizumab for ocular vascular diseases including diabetic macular edema, neovascular age-related macular degeneration, myopic choroidal neovascularization, retinal vein occlusion and central serous chorioretinopathy. METHODS Twenty clinical questions were developed by the guideline technical committee. Relevant websites and databases were searched to find out the pertinent clinical practice guidelines to answer the questions. The technical committee provided possible answers (scenarios) according to the available evidences for each question. All scenarios along with their levels of evidence and the supported articles were sent to the experts for external review. If the experts did not agree on any of the scenarios for one particular clinical question, the technical committee reviewed all scenarios and their pertinent evidences and made the necessary decision. After that, the experts were asked to score them again. All confirmed scenarios were gathered as the final recommendations. RESULTS All the experts agreed on at least one of the scenarios. The technical committee extracted the agreed scenario for each clinical question as the final recommendation. Finally, 56 recommendations were developed for the procedure of intravitreal anti-VEGF injection and their applications in the management of ocular vascular diseases. CONCLUSION The implementation of this guideline can standardize the management of the common ocular vascular diseases by intravitreal injection of anti-VEGF agents. It can lead to better policy-making and evidence-based clinical decision by ophthalmologists and optimal evidence based eye care for patients.

Abstract
Purpose: To customize clinical practice guidelines (CPGs) for management of diabetic retinopathy (DR) in the Iranian population. Methods: Three DR CPGs (The Royal College of Ophthalmologists 2013, American Academy of Ophthalmology [Preferred Practice Pattern 2012], and Australian Diabetes Society 2008) were selected from the literature using the AGREE tool. Clinical questions were designed and summarized into four tables by the customization team. The components of the clinical questions along with pertinent recommendations extracted from the above-mentioned CPGs; details of the supporting articles and their levels of evidence; clinical recommendations considering clinical benefits, cost and side effects; and revised recommendations based on customization capability (applicability, acceptability, external validity) were recorded in 4 tables, respectively. Customized recommendations were sent to the faculty members of all universities across the country to score the recommendations from 1 to 9. Results: Agreed recommendations were accepted as the final recommendations while the non-agreed ones were approved after revision. Eventually, 29 customized recommendations under three major categories consisting of screening, diagnosis and treatment of DR were developed along with their sources and levels of evidence. Conclusion: This customized CPGs for management of DR can be used to standardize the referral pathway, diagnosis and treatment of patients with diabetic retinopathy.

Abstract
PURPOSE To evaluate the outcome of scleral buckling surgery in patients with rhegmatogenous retinal detachment (RRD) with subretinal proliferation. METHODS In this retrospective study, a chart review of all patients with RRD associated with subretinal proliferation who were primarily treated with scleral buckling procedure, from April 2007 to April 2014, was undertaken. Main outcome measures were anatomical retinal reattachment and visual acuity. RESULTS Forty-four eyes of 43 patients including 24 males and 19 females with a mean age of 26.5±13.1 years were evaluated. Immediately after the surgery, retina was reattached in all eyes. However, five eyes (11.3%) needed additional surgery for retinal redetachment. Single surgery anatomical success rate was 88.7%. Four eyes (9.1%), needed pars plana vitrectomy for the treatment of redetachment associated with proliferative vitreoretinopathy and scleral buckle revision surgery was successfully performed in the other eye. Best corrected visual acuity improved from 1.5±0.9 logMAR before surgery to 1.1±0.7 logMAR after surgery (P<0.001). An improvement in BCVA of >2 lines was found in 23 eyes (52.2%) and worsening of best corrected visual acuity of >2 lines was observed in 2 eyes (4.5%). CONCLUSIONS Scleral buckling surgery is highly successful in eyes with RRD associated with subretinal proliferation.

Abstract
PURPOSE To determine the frequency of complement factor H (Y402H) and age related macular degeneration susceptibility gene 2 (A69S) single nucleotide polymorphisms in patients with age-related macular degeneration (AMD) and in matched non-AMD controls in an Iranian population. METHODS Seventy patients with AMD and 86 age- and sex-matched controls were recruited and examined. Peripheral blood sample was obtained from all subjects for DNA extraction and direct sequencing of Y402H and A69S genes. Odds ratios (ORs) with 95% confidence intervals (CIs) for the association of Y402H and A69S polymorphisms with AMD were determined. RESULTS The frequencies of both homozygous and heterozygous genotypes were significantly higher in cases than controls for both Y402H and A69S polymorphisms. In comparison to the wild genotypes, OR for AMD associated with Y402H and A69S polymorphisms were 1.9 (95% CI, 1.1-3.2) and 2.2 (95%CI, 1.6-3.1), respectively. Joint risk analysis considering both genes revealed a higher risk of AMD when polymorphisms were present for both genes. CONCLUSION Y402H and A69S polymorphisms were strongly associated with AMD in this Iranian population.

Abstract
PURPOSE To evaluate the visual and anatomic results and determine the prognostic factors after pars plana vitrectomy and posterior segment intraocular foreign body (IOFB) removal. MATERIALS AND METHODS This retrospective study reviews the patients' charts of 48 consecutive patients with posterior segment IOFB who underwent pars plana vitrectomy and IOFB removal over a 4-year period, recently. Association between visual outcome and various preoperative, operative, and postoperative variables was statistically analyzed. Data were analyzed with the paired t-test and the chi square test. Statistical significance was indicated by P < 0.05. RESULTS The mean interval between the time of injury and IOFB removal was 24 ± 43.1 days and 27 (53%) eyes underwent IOFB removal within 7 days of the injury. Nine (19.1%) patients achieved a visual acuity of 20/40 or better. An improvement of visual acuity of at least three lines occurred in 21 (44.6%) eyes and the vision remained unchanged in 15 (31.9%) eyes. Postoperative retinal detachment occurred in five (10.6%) eyes. Visual improvement was more likely to occur in eyes with lower levels of presenting visual acuity (P = 0.2). Visual improvement was not associated with an entry site and IOFB location, lens injury, time to surgery, and pre- and post-operative retinal detachment. At the end of follow up, anatomical success was achieved in 97.9% of eyes. CONCLUSIONS High anatomical success could be achieved after the removal of posterior segment IOFBs by vitrectomy, despite a delay in surgery. Poor visual outcome may be mainly due to the initial ocular injury.

Abstract
PURPOSE To report the outcomes of transscleral diode laser photocoagulation for treatment of type 1 prethreshold retinopathy of prematurity (ROP). METHODS In this prospective interventional case series, 139 eyes of 73 infants with type 1 prethreshold ROP underwent transscleral diode laser photocoagulation of the avascular retina under topical anesthesia without making a conjunctival incision. Supplemental transpupillary diode laser photocoagulation was used for zone 1 ROP in one eye. All patients were followed for 6 months. Main outcome measures were regression of ROP, incidence of unfavorable outcomes and adverse effects. RESULTS At the end of follow-up, neovascularization regressed completely in all eyes and no eye developed an unfavorable outcome. Repeated laser therapy was performed employing the same technique in 3 eyes (2.3%). Ocular adverse effects were minor including mild conjunctival injection and edema in all patients, small conjunctival lacerations in 12 eyes (8.7%), minor self-limited vitreous hemorrhage in 2 eyes (1.4%) and mild self-limited hyphema in one eye (0.7%). CONCLUSION Transscleral diode laser photocoagulation is a safe and effective treatment option for type 1 prethreshold ROP. This technique can be performed under topical anesthesia.

Abstract
PURPOSE To evaluate outcomes of intravitreal injection of bevacizumab for the treatment of severe retinopathy of prematurity (ROP) associated with vitreous or retinal hemorrhages (VH or RH). METHODS This is a prospective interventional case-series. Fourteen eyes of eight premature infants with severe ROP associated with vitreous or retinal hemorrhage were consecutively included. In eight eyes, VH and/or RH precluding complete laser ablation developed at the time of laser treatment. In six eyes, VH developed early after laser ablation. All participants underwent intravitreal injection of 0.625 mg (0.025 ml) bevacizumab immediately after diagnosis of VH or RH. Follow-up examinations were performed at days 1, 3, 7, and 14, and 1, 2 and 3 months after injection. Main outcome measure was the absence of unfavorable structural outcomes. RESULTS Mean gestational age was 27.6 weeks (range, 26-29 weeks) and mean birth weight was 1047 g (range, 780-1500 g). Mean gestational age at the time of injection was 35.4 weeks (range, 32-38 weeks). In all eyes, plus disease disappeared completely within 2 weeks and VH and/or RH was absorbed at last follow-up. None of the eyes developed unfavorable structural outcomes. No eyes needed additional injection or laser treatment. No major systemic or ocular complications were observed. CONCLUSION In this small series of patients, intravitreal injection of bevacizumab was effective for treatment of severe retinopathy of prematurity associated with vitreous or retinal hemorrhage.

METHODS Retrospective interventional case series of infants with ROP treated at our center with transscleral diode laser retinal photocoagulation. All patients were followed for 2 months, and regression of ROP, unfavorable outcomes, and incidence of adverse effects were assessed. RESULTS A total of 103 eyes of 52 infants with ROP at the threshold stage were treated with transscleral diode laser photocoagulation under topical anesthesia, without conjunctival incision. Supplemental transpupillary diode laser photocoagulation was used for posterior zone 2 and zone 1 in 5 eyes. In 99 eyes (96.1%) neovascularization regressed completely; in 96 eyes (93.2%) the outcome was favorable. In the other 3 eyes, macular dragging formed after regression of neovascularization. Four eyes progressed to more advanced stages of ROP. Repeated laser therapy was performed with the same technique in 10 eyes (9.6%). There was no statistically significant association of unfavorable outcomes with age, birth weight, gestational age, clocks of retinal involvement, and rush disease. No adverse effects of diode laser treatment were observed except for mild injection and edema of conjunctiva in all patients, small conjunctival lacerations in 10 eyes, and small self-limited vitreous hemorrhage in 2 eyes. CONCLUSIONS Transscleral laser treatment may be technically easier for the treatment of retinal periphery, especially in poorly dilating pupils, and obviates the occasional anterior segment complications of the transpupillary approach. This technique can be performed under topical anesthesia.

Abstract
Osteiod osteoma is a small, benign, osteoblastic tumor, which usually affects the long bone of the lower extremities and vertebrae. Herein, we report the first case of endo-orbital osteoid osteoma. A 22-year-old man presented with eyelid edema, proptosis and pain in the left eye 1 year after the beginning of the symptoms. Imaging studies showed a small (15 x 11 mm in size) lesion on the roof of the left orbit with contrast enhancement. The lesion was removed and histopathological section was consistent with osteoid osteoma. Eighteen month after the operation, the patient was free of symptoms.

Abstract
AIMS To find the cure rate of late (second year of age) and very late (3-5 years of age) initial probing for congenital nasolacrimal duct obstruction (CNLDO) and to identify the factors contributing to the failure rate of the probing in older children. METHODS In a prospective interventional case series study, 169 eyes of 125 consecutive patients (1-5 years old) with CNLDO underwent probing under general anaesthesia. Cure was defined as absence of tearing and discharge in the affected eye. RESULTS 138 eyes of 101 patients aged 13-60 months (mean 23.4 (SD 10.2)) were included. Of 15 eyes (10.8%) with complex CNLDO, 80% presented after 24 months of age (p<0.0001). The cure rate was 89% in patients 13-24 months of age and 72% after the age of 24 months (p = 0.01). It was 90.2% in the membranous and 33.3% in the complex CNLDO in both late and very late probing (p<0.0001). There was a high correlation (r = 0.97) and no significant difference between the cure rate at 1 week and final follow up. CONCLUSION Accumulation of the complex CNLDO is the main risk factor for failure of probing in the older children. The outcome of the nasolacrimal duct probing at 1 week follow up is highly indicative of the final outcome.

Accidental subretinal injection of triamcinolone acetonide. OPHTHALMIC SURGERY AND LASERS 1998; 29:935-8. [PMID: 9824868] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 02/09/2023]
Abstract
Approximately one-third of the contents of a 1-ml, 40-mg ampule of triamcinolone acetonide was accidentally injected into the subretinal space of the left eye of a 30-year-old man with chronic uveitis. The manufacturer provided a list of the contents of the ampule. A large, white subretinal mass was seen in the superotemporal quadrant. In subsequent days, the medication was seen to migrate inferiorly. Visual acuity in the left eye was 20/400. Subretinal hemorrhage and mild atrophy of the retinal pigment epithelium and choroid were observed superotemporally. Visual acuity returned to 20/100 (preinjection level) in 1 week. Four months postinjection, the superotemporal atrophy was more severe; the inferotemporal medication was minimally visible without producing significant chorioretinal atrophy. The visual acuity remained at 20/100 until the patient underwent cataract extraction and intraocular lens implantation; his vision then improved to 20/40. Steroids, when not accompanied by harmful vehicle substances, may be well tolerated by ocular tissues.

Abstract
PURPOSE To report ocular perforation that occurred during retrobulbar injection in 7 highly myopic eyes. METHODS Seven patients with a diagnosis of globe injury during retrobulbar injection for ocular anesthesia before cataract surgery were managed by vitreoretinal surgery. All injections were performed by ophthalmologists. The surgeon recognized the perforation in 4 cases at the time of injection. The preoperative vision was hand motion perception in 4 eyes and light perception in 3 eyes. All patients underwent vitreoretinal surgery because of the presence of vitreous hemorrhage and/or retinal detachment diagnosed by funduscopy or ultrasonography. At the time of surgery, all eyes had vitreous hemorrhage and 4 eyes had rhegmatogenous retinal detachment. The number of vitreoretinal procedures performed was: 1 procedure in 4 patients, 2 procedures in 2 patients, and 3 procedures in 1 patient. The period of follow-up ranged from 4 months to 4 years, averaging 20 months. RESULTS At the end of the follow-up period, the retina was attached in 6 patients. The postoperative vision was 20/400 in 3 eyes, finger counting in 3 eyes, and light perception in 1 eye. CONCLUSION Special care should be taken in retrobulbar injection of highly myopic globes, which have an increased risk of perforation. The functional outcome of surgical repair of these eyes was poor.
