Outcomes of pars plana vitrectomy in the management and diagnosis of patients with infectious, non-infectious, and unidentified uveitis.

PURPOSE: To present the outcomes of pars plana vitrectomy (PPV) in patients with infectious, non-infectious, and unidentified uveitis, focusing on visual and clinical outcomes, diagnostic yield, and surgery-related complications. METHODS: This retrospective, single-center study included patients who underwent 23-gauge PPV for the management of uveitis and had at least 6 months of follow-up. Patients were divided into infectious, non-infectious, and unidentified uveitis groups based on definitive diagnosis after surgery. Etiologies of uveitis, indications for surgery, diagnostic yield, visual outcomes, presence of cystoid macular edema (CME), immunosuppressive drugs, intraoperative and postoperative complications, and repeated vitrectomies were reviewed. RESULTS: This study included 62 eyes of 54 patients. Twenty eyes were diagnosed with infectious uveitis, 24 eyes with non-infectious uveitis, and 18 eyes with unidentified uveitis. The diagnostic yield of vitrectomy was 41.7%. Mean BCVA significantly improved at postoperative 1 month compared to baseline and remained stable at following time-points in all groups. The most common early postoperative complication was increased intraocular pressure (17%), and late complication was cataract (36%). Nine eyes underwent re-vitrectomy and the most common cause was retinal detachment with proliferative vitreoretinopathy (PVR). CONCLUSION: PPV seems to be effective in diagnosing cases of unknown origin, improving visual acuity, and reducing the need for systemic immunosuppressive drugs. PVR is the most serious complication with poor prognosis that requires repeated surgery in patients with uveitis.

Visual outcomes after treatment of craniopharyngioma in children: A systematic review.

OBJECTIVE: Craniopharyngiomas (CP) are rare brain tumors that often result in visual impairment due to their proximity to the optic pathway. The optimal management approach to preserve visual function in these patients remains controversial. We sought to investigate visual outcomes of children with craniopharyngiomas based on treatment modality. METHODS: A systematic review was performed according to PRISMA guidelines. PubMed, Embase, and Scopus databases were searched in December 2022 for relevant articles. Articles were screened by title/abstract for relevance, then by full-text. Relevant demographic, intervention, and outcome data were extracted from included studies. RESULTS: A total of 59 studies were included, representing 2655 patients. The overall visual status (OVS) of patients receiving surgery alone was improved in 27.6% of reported outcomes, unchanged in 50.3%, and deteriorated in 22.1%. The OVS for patients receiving radiation alone was improved in 21.1%, unchanged in 42.1%, and deteriorated in 36.8%. Patients receiving surgery plus adjuvant radiotherapy had OVS improvement in 27.4%, unchanged in 63.2%, and deteriorated in 9.4%. Of those receiving intracystic bleomycin, 23.1% had improvement in OVS, 46.2% remained unchanged, and 30.8% deteriorated. Of patients receiving interferon-α, 34.8% improved, 54.5% remained unchanged, and 10.6% deteriorated. CONCLUSION: OVS most frequently remained unchanged regardless of intervention. The greatest improvement in OVS was seen in those receiving interferon-α or surgery alone. The greatest OVS deterioration was noted with radiation alone. Future standardized, randomized, large-scale studies with focused assessment of ophthalmologic findings are key to further understanding the impact different interventions have on visual outcomes in these children.

Complications and visual outcomes following surgical resection of pediatric optic pathway/hypothalamic gliomas: a systematic review and meta-analysis.

Pediatric optic pathway/hypothalamic gliomas (OPHG) pose challenges in treatment due to their location and proximity to vital structures. Surgical resection plays a key role in the management of OPHG especially when the tumor exhibits mass effect and causes symptoms. However, data regarding outcomes and complications of surgical resection for OPHG remains heterogenous. The authors performed a systematic review on pediatric OPHG in four databases: PubMed, EMBASE, Cochrane Library, and Google Scholar. We included studies that reported on the visual outcomes and complications of OPHG resection. A meta-analysis was performed and reported per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A total of 26 retrospective studies were included. Seven hundred ninety-seven pediatric patients with OPHG undergoing surgical resection were examined. A diagnosis of NF1 was confirmed in 9.7%. Gross total resection was achieved in 36.7%. Intraorbital optic pathway gliomas showed a significantly higher gross total resection rate compared to those located in the chiasmatic/hypothalamic region (75.8% vs. 9.6%). Postoperatively, visual acuity improved in 24.6%, remained unchanged in 68.2%, and worsened in 18.2%. Complications included hydrocephalus (35.4%), anterior pituitary dysfunction (19.6%), and transient diabetes insipidus (29%). Tumor progression post-resection occurred in 12.8%, through a mean follow-up of 53.5 months. Surgical resection remains an essential strategy for treating symptomatic and large pediatric OPHG and can result in favorable vision outcomes in most patients. Careful patient selection is critical. Patients should be monitored for hydrocephalus development postoperatively and followed up to assess for tumor progression and adjuvant treatment necessity.

Epiretinal membrane in uveitis: Rate, visual prognosis, complications and surgical outcomes.

BACKGROUND: Epiretinal membrane (ERM) is a common finding in patients with uveitis that contributes to visual impairment. We describe the long-term visual acuity (VA) and morphometric progression in patients with uveitis and epiretinal membrane (ERM). METHODS: Retrospective cohort study of patients with uveitic ERM from a tertiary centre database. Multivariate analysis of risk factors for ERM progression was calculated using a marginal Cox regression model to estimate hazard ratios (HR). RESULTS: Two hundred and sixteen eyes (4%) of a total 5450 eyes with uveitis were identified to have an ERM. The most common diagnosis was idiopathic uveitis in 45 patients (28.7%), followed by sarcoidosis in 21 (13.4%), HLAB27-related uveitis in 15 (9.6%) and toxoplasmosis in 15 (9.6%). Risk factors for ERM development include age (HR 1.03), intermediate uveitis (HR 2.33), posterior uveitis (HR 1.53) and ERM fellow eye (HR 18.28). Anterior uveitis (HR 0.53) and alternating disease (HR 0.53) were protective. Median VA was 20/40 at diagnosis of ERM and 20/40 at final follow up. Progression of ERM grade occurred in 17 eyes (7.9%) during the study period. ERM peel was performed in 44 eyes (20.4%). Median VA was 20/60 and 20/40 at baseline and 12 months after surgery, respectively. Improvement in visual acuity occurred in 23 eyes (60.5%) following surgery. CONCLUSIONS: In addition to intermediate and posterior uveitis, fellow eye involvement is a strong risk factor for ERM development. In treated uveitis, the majority maintain their long-term vision and rates of ERM progression are low.

Visual outcomes and optimal timing for repeat surgery in cases of postoperative hematoma following transsphenoidal surgery for pituitary neuroendocrine tumors: A retrospective cohort study.

OBJECTIVE: To investigate the visual outcomes and optimal timing for repeat surgery in cases of postoperative hematoma following transsphenoidal surgery for pituitary neuroendocrine tumors (PitNETs). METHODS: A retrospective study was conducted on 28 patients who developed evident postoperative hematoma out of a total of 9,010 patients. The hematomas were classified into three types based on their CT appearance. Type 1a - mild high density with no tension, Type 1b - thin-layer high density; Type 2a - solid high density with large empty cavities, Type 2b - solid high density with small empty cavities; Type 3 -solid high density with no cavity showing high tension. Patient data were collected for analysis. RESULTS: The study cohort comprised 10 female and 18 male patients, with a mean age of 51.5±11.9 years. Most patients presented with large adenomas (median diameter 36mm). Postoperative visual sight improved in 12 patients, remained stable in 11 patients, and worsened in 5 patients. Notably, no patients experienced worsened visual sight beyond twenty-four hours after the operation. Among the five patients with visual deterioration, four had CT type 3 hematoma (4/6, 66.7%), and one had CT type 2b hematoma (1/9, 11.1%). Patients in the type 3 CT group were significantly more prone to experience visual deterioration compared to those in the type 2 group (odds ratio [OR] 2.154 [95% CI 1.858-611.014], P=.027). Four patients underwent repeat surgery after visual deterioration, resulting in visual improvement following a prolonged recovery period. Postoperative hematoma had limited impact on pituitary dysfunction and hyponatremia. CONCLUSION: Our study reveals a significant association between postoperative hematoma CT types and visual deterioration. For patients with stable visual sight and type 1 or 2a hematoma, conservative strategies may be considered. Conversely, type 2b and 3 patients are at higher risk of visual deterioration, especially within the first 24 hours after the operation. Consequently, early reoperation before vision worsens may be a prudent approach to reduce risks and improve visual outcomes, particularly in type 3 patients.

Factors influencing postoperative visual improvement in 208 patients with tuberculum sellae meningiomas.

OBJECTIVE: Tuberculum sellae meningiomas (TSMs) usually compress the optic nerve and optic chiasma, thus affecting vision. Surgery is an effective means to remove tumors and improve visual outcomes. On a larger scale, this study attempted to further explore and confirm the factors related to postoperative visual outcomes to guide the treatment of TSMs. METHODS: Data were obtained from 208 patients with TSMs who underwent surgery at our institution between January 2010 and August 2022. Demographics, ophthalmologic examination results, imaging data, extent of resection, radiotherapy status, and surgical approaches were included in the analysis. Univariate and multivariate logistic regressions were used to assess the factors that could lead to favorable visual outcomes. RESULTS: The median follow-up duration was 63 months, and gross total resection (GTR) was achieved in 174 (83.7%) patients. According to our multivariate logistic regression analysis, age < 60 years (odds ratio [OR] = 0.310; P = 0.007), duration of preoperative visual symptoms (DPVS) < 10 months (OR = 0.495; P = 0.039), tumor size ≤ 27 mm (OR = 0.337; P = 0.002), GTR (OR = 3.834; P = 0.006), and a tumor vertical-to-horizontal dimensional ratio < 1 (OR = 2.593; P = 0.006) were found to be significant independent predictors of favorable visual outcomes. CONCLUSION: Age, DPVS, tumor size, GTR, and the tumor vertical-to-horizontal dimensional ratio were found to be powerful predictors of favorable visual outcomes. This study may help guide decisions regarding the treatment of TSMs.

The effect of phacoemulsification on visual function among Filipino cataract patients measured by a validated Filipino translation of Catquest-9SF.

BACKGROUND: This study developed a validated Filipino version of the Catquest-9SF and administered it to cataract patients pre- and post- surgery. METHODS: This is a two-phase, single-center, cross sectional, questionnaire type study. The study included participants decked for surgery who are 18 years and above. Sampling was done purposively. The Catquest-9SF questionnaire was translated into Filipino, according to a standard procedure, and validated. The validated version was administered to the participants before and after unilateral cataract surgery. Data were analyzed using Rasch analysis. RESULTS: Sixty-one patients were enrolled in the study. The preliminary Rasch analysis showed misfit of item 2, which was subsequently excluded from analysis. The remaining eight items showed person separation index of 2.70, reliability coefficient of 0.88, infit of 0.66 to 1.17, outfit of 0.66 to 1.49, observed raw variance explained by measures of 55.3% and eigenvalues of 1.9, 1.4, 1.2, 1.0 and 0.9. There was slightly poor targeting (mean person location 1.24) and multidimensionality but no evidence of differential item functioning (DIF). High internal consistency of items were observed (Cronbach's alpha ≥ 90). Comparison of responses between pre- and post-surgery showed highly significant marginal homogeneity (p < 0.001). CONCLUSION: The Filipino translation of Catquest-9SF, the Catquest-8SF-PH, was highly valid. It showed improved perceived visual outcomes among Filipino patients post-cataract surgery.

Dilated choroidal vascular channels in pachychoroid neovasculopathy.

BACKGROUND: To elucidate the pattern of the choroidal vasculature in exudative pachychoroid neovasculopathy (PNV) and its correlation with the clinical course and treatment outcomes. METHODS: The retrospective study included consecutive patients in National Taiwan University Hospital between 2014 and 2020 who fulfilled the criteria for exudative PNV defined as active type 1 macular neovascularization (MNV) on optical coherence tomography angiography (OCTA) and with leakage on fluorescein angiography (FA) or indocyanine green angiography (ICGA) associated with pachychoroid features. The corrected distance visual acuity (CDVA), FA, ICGA, and OCT images obtained by Optovue (Optovue Inc, Freemont CA, USA) spectral domain OCT were evaluated at baseline and various time points during the 12-month treatment period. The correlations between the choroidal vascular patterns, specifically those with or without dilated choroidal vascular channels (DCVC) revealed by ICGA, and baseline characteristics and treatment outcomes were evaluated using multiple regression models. RESULTS: The study enrolled 34 eyes of 31 patients. The average age was 59.0 ± 9.3 years, and 20 participants were men. ICGA revealed DCVCs in 21 eyes, while the remaining 13 eyes did not have DCVCs. At baseline, DCVC group was older (p = 0.03) and had a longer duration of visual symptoms (p = 0.02), with a higher vessel density (defined as the percentage of the measured area occupied by flow area) of MNV (p = 0.04), higher proportion of ellipsoid zone disruption (p = 0.01), and poorer CDVA (p = 0.03). After the 12-month treatment period, the frequency of requirement of anti-VEGF injections (p < 0.01) was higher, and the risk for CDVA <20/40 was higher (adjusted OR: 5.29, 95% CI: 1.24-22.48, p = 0.02) in eyes with DCVCs. CONCLUSIONS: For PNV, eyes with DCVCs were associated with higher vessel density of macular neovascularization and poorer CDVA at baseline, and had poorer visual and anatomical outcomes although more anti-VEGF injections were given.

Ten-year mortality and long-term visual acuity outcomes in patients with exudative age-related macular degeneration treated with intravitreal anti-vascular endothelial growth factor injections.

PURPOSE: There are limited real-world data on long-term mortality and visual outcomes in patients treated with anti-vascular endothelial growth factor (VEGF) for exudative age-related macular degeneration (exudative AMD). We assessed 10-year mortality and clinical outcomes in exudative AMD patients treated with intravitreal therapy (IVT) anti-VEGF injections on a pro-re-nata (PRN) regime following a standard loading regime. METHODS: Retrospective cohort study of the first 216 exudative AMD patients receiving IVT anti-VEGF for exudative AMD at a public tertiary referral hospital in Scotland. Main outcome measures were mortality, cause of death and best-corrected visual acuity (BCVA). RESULTS: A total of 216 patients were included. Mean age at presentation was 79.1 years [standard deviation (SD) 6.9]. Mean follow-up duration was 6.6 years (SD 3.2) during which there was a mean 24.3 Early Treatment Diabetic Retinopathy Study (ETDRS) letter loss in BCVA (P < 0.0001). Patients received a mean of 2.2 (SD 1.8) injections per year of follow-up. Overall, 52.6% (113/216) died during the period studied. Observed annual mortality incidence risk was 6.5% (SD 3.1) and was found to be significantly lower (P = 0.0064) than the expected annual death incidence risk (9.6%, SD 1.5) based on age and sex standardised Scottish mortality risk. The most common causes of death were malignancies (21.3%) and infection (20.0%). CONCLUSIONS: This study highlights the relatively good long-term prognosis in vision and mortality in exudative AMD treated with a PRN regime in the real world. Although the majority lost vision, the rate of decline was significantly slower than that which would have been experienced in the pre-anti-VEGF era and reassuringly standardised mortality risk was lower than the national average.

Clinical characteristics and mortality rates for suprachoroidal hemorrhage: seven-year experience at a tertiary eye center.

PURPOSE: To investigate comorbidities and medications associated with acute (ASCH) and delayed (DSCH) suprachoroidal hemorrhage (SCH), and to explore visual outcomes and mortality following SCH. METHODS: Retrospective review of SCH cases diagnosed at a tertiary center between 2013 and 2019. Demographics, history, surgery type, visual acuity, intraocular pressure (IOP), and mortality data were reviewed. RESULTS: Fifty eyes of 50 patients experienced SCH related to surgery: 15 (30%) ASCH and 35 (70%) DSCH. Glaucoma surgery was the most common preceding surgery, and SCH was more likely to be delayed in glaucoma surgery relative to other surgeries (p = 0.001). The proportions of patients on anticoagulant, antiplatelet, or NSAID medications were 30% (n = 15), 52% (n = 26), and 12% (n = 6), respectively. The mean preoperative IOP was 25.0 ± 10.2 mmHg. The mean final best corrected visual acuity did not significantly differ between DSCH and ASCH (logMAR 1.92 vs. 2.36; p = 0.39). After controlling for pre-drainage visual acuity, final visual acuity was not statistically significantly different between eyes that were drained versus those that were not drained (p = 0.06). Of all 50 patients, the mortality rate was 12% with a mean time to mortality after SCH of 754 ± 564 days for those who died. CONCLUSION: DSCH was more common than ASCH, with glaucoma surgery being the most common procedure to result in SCH. Visual outcomes and mortality rate were comparable between ASCH and DSCH. Further research is needed regarding the role of surgical drainage on improving visual outcomes in eyes with SCH.

Effect of surgical timing in 23-g pars plana vitrectomy for primary repair of macula-off rhegmatogenous retinal detachment, a retrospective study.

BACKGROUND: Rhegmatogenous retinal detachment (RRD) is a common, potentially blinding ocular pathology that is considered a surgical emergency. Macular involvement has been identified as a major negative prognostic indicator for visual recovery after RRD correction. It is not currently clear whether early intervention improves visual outcomes, and in practice, there are potential disadvantages to performing early surgery for fovea-involving RRD. Such disadvantages include inadequate assessment of coexisting comorbidities, increased rate of complications related to poorly trained staff or tired surgeons, and anesthetic risk. METHODS: A single-center, retrospective, cohort study of patients who underwent repair of macula-involving rhegmatogenous retinal detachment at the University of Virginia was performed. Variables collected included patient demographics, ocular history, clinical characteristics, and post-operative complications. Patients were excluded if they had a history of congenital or acquired pathology with an effect on visual function, bilateral or repeat rhegmatogenous detachment, age less than 18 years, follow up duration less than 6 months, or if they were repaired using scleral buckle, pneumatic retinopexy, 25- or 27-gauge pars plana vitrectomy, or any combination of these techniques. A multivariate regression model was used to compare overall outcomes such as post-operative visual acuity, intra-ocular pressure, retina attachment status, and complications among patients of differing timing of surgical repair. These analyses were adjusted for clinical factors known or considered to be associated with worse prognosis in rhegmatogenous retinal detachment. RESULTS: A total of 104 patients undergoing 23-gauge vitrectomy for repair of macula involving rhegmatogenous retinal detachments were included in this study with mean follow up period 17.9 ± 14.1 months. Early surgical repair (< 48 h) was pursued in 26 patients, moderately delayed surgical repair (3-7 days), was performed in 29 patients and late surgical repair (> 7 days) in 49 patients. Our analysis showed no difference in post-operative visual acuity between patients with detachments undergoing early versus moderately delayed repair of RRD. However, mean visual acuity differed between patients undergoing early versus late repair at 3, 6, and 12 months. No significant difference was observed in post-operative complications between the three surgical timepoints including cataract formation, development of glaucoma and re-detachment rate. Use of 360 laser was found to be protective against re-detachment overall (OR 6.70 95% CI 1.93-23.2). CONCLUSIONS: These findings indicate that a moderate delay of 3-7 days from symptom onset for repair of macula-involving retinal detachment may be a safe approach as there are no differences in terms of visual acuity or post-operative complications compared to early repair within 48 h. Delaying surgery for > 7 days however is not recommended due to the loss of recovery of visual acuity observed in this study. Use of 360 laser may prevent risk of re-detachment after primary repair.

Outcomes of corneal transplantation in Australia, in an era of lamellar keratoplasty.

Widespread adoption of modern lamellar procedures has altered the pattern of practice of corneal transplantation. Herein, we describe recent findings from the Australian Corneal Graft Registry and place these data into an international context. The total number of grafts reported to the Registry has doubled over the past decade. Deep anterior lamellar keratoplasty is increasingly used for keratoconus, while endokeratoplasty has displaced penetrating keratoplasty for Fuchs endothelial dystrophy. Graft survival and visual outcomes for modern lamellar procedures have shown improvement over time. First deep anterior lamellar and penetrating grafts for keratoconus show comparable survival and long-term best-corrected visual acuity is equivalent. Penetrating grafts for Fuchs endothelial dystrophy exhibit significantly better survival than do endokeratoplasties, largely because the latter undergo more early graft failures. However, visual rehabilitation is swifter in surviving endokeratoplasties. Significantly fewer recipients of a deep anterior lamellar graft or endokeratoplasty require spectacle or contact lens correction, compared with penetrating keratoplasty.

Efficacy, safety and visual outcomes of cataract surgeries performed during blindness prevention programs in different locations in Kenya.

PURPOSE: To determine the visual outcomes achieved in terms of efficacy and safety during high-volume cataract surgery programs in different locations in Kenya. METHODS: Eight hundred eighty-one eyes of 849 patients underwent extracapsular cataract extraction with intraocular lens implantation in a retrospective, observational, consecutive cohort study on patients who underwent cataract surgery in five programs that a Spanish non-governmental organization conducted between 2013 and 2019 for the prevention of blindness in different geographical areas of Kenya: Thika, Athi River, Kissi, Bagavathi, and Nakuru. The programs were carried out by Spanish and Kenyan surgeons working together. RESULTS: Mean age was 66.81 ± 14.47 years. Fifty-one percent of the operated eyes (447 eyes) were women. 94% of patients belonged to six ethnic groups. The mean uncorrected distance visual acuity (UDVA) before surgery was 1.98 ± 0.98 logMAR (20/2000), which changed to 0.82 ± 0.68 logMAR (20/150) 3 months after surgeries. The corrected distance visual acuity (CDVA) was 0.4 ± 0.53 logMAR (20/50) 3 months after surgery, 77.5% of the patients had good visual outcomes, and 6.3% had poor outcomes. Preoperative UDVAs were significantly different with respect to the different geographical areas (Kruskal-Wallis; p < 0.001). The most common intraoperative complication was posterior capsule rupture (incidence, 4.2%, 37 of 881), and the most serious complication was expulsive hemorrhage (incidence, 0.1%, 1 of 881). CONCLUSIONS: Cataract programs performed in a middle-income country with the proper technique and standardized protocols of action improved the visual outcome of the patients. Dissimilar baseline status was found in different areas regarding preoperative visual acuities. Training programs of local surgeons should be reinforced.

Intracystic hyperreflective material in centre-involving diabetic macular oedema.

PURPOSE: To report evolution and predictive value of intracystic hyperreflective material (ICHRM) on optical coherence tomography (OCT) in centre-involving diabetic macular oedema (CI-DME). METHODS: Demographic and OCT features of patients with treatment-naïve CI-DME were analysed retrospectively. OCT parameters noted were macular oedema type, ICHRM presence, presence of hyperreflective spots, disorganised inner retinal layers and outer retinal layers integrity. Eyes were grouped into group 1 CI-DME without ICHRM and group 2 CI-DME with ICHRM. Univariate and multivariate linear regression analyses were done to study the correlation between various OCT features and final vision. RESULTS: In this study, 62 eyes of 50 patients were included in group 1 and 61 eyes of 51 patients in group 2. Mean presenting logMAR vision in groups 1 and 2 was 0.374 ± 0.346 and 0.523 ± 0.369 respectively. Poor final visual acuity was noted in CI-DME with ICHRM group (p = 0.015). On linear regression analysis, 3 OCT features, namely, ICHRM presence (p = 0.034), inner segment-outer segment layer disruption (p = 0.001) and ellipsoid zone defects (p = 0.003), were associated with poor final vision. More intravitreal anti-VEGF (2.98 vs 0.629) and steroid (1.51 vs 0.242) injections were required for macular oedema resolution in ICHRM group. CONCLUSION: This study is the first to assess the ICHRM on OCT as predictor for treatment outcome in DME eyes. We described its evolution during the DME management and its plausible influence on intravitreal therapy. We believe that this finding has the potential to become a novel biomarker for predicting the visual outcome in DME.

Visual acuity and anatomical changes following vitrectomy for epiretinal membrane foveoschisis: a case series.

PURPOSE: To evaluate the visual outcome and macular anatomic structures on spectral-domain optical coherence tomography (SD-OCT) of patients with epiretinal membrane (ERM) foveoschisis who underwent vitrectomy. METHODS: A retrospective cohort, interventional, case series. PARTICIPANTS: Fourteen patients (14 eyes) with central vision loss from an ERM foveoschisis underwent vitrectomy at Chiang Mai University Hospital from 2017 to 2018 and had a follow-up period of 12 months. INTERVENTIONS: The 23G vitrectomy with ERM and internal limiting membrane (ILM) peeling was performed by a single surgeon. MAIN OUTCOMES: Best-corrected visual acuity (BCVA) and anatomic appearance on SD-OCT were assessed at the time of preoperative evaluations and post-operative follow-ups at 1, 3, 6, and 12 months. RESULTS: Fourteen patients with a mean (SD) age of 67.9 (7.9) years and a mean (SD) visual acuity (VA) of 0.6 (0.1) LogMAR units were included in this study. Significant VA improvements were observed at the 3-month (0.43 (0.14) LogMAR unit), 6-month (0.45 (0.16) LogMAR unit) and 12-month (0.37 (0.21) LogMAR unit) post-operative visits compared to baseline, all with P-values < 0.001. At month 12, there were vision improvements of ≥3 lines in 8 (57.2%) patients, vision improvements of 1 or 2 lines in 2 (14.3%) patients, vision remained at the same line of pre-operation in 3 (21.4%) patients, and vision decreased by 1 line in 1 (7.1%) patient. Regarding the anatomical outcomes, 13 (92.9%) patients achieved anatomical foveal restoration, while one had persistent intraretinal schisis at the 12-month follow-up. The median time to achieve a foveal restoration was 3 months. No significant visual impairments were observed post-operatively. CONCLUSION: In patients with central vision loss from ERM foveoschisis, vitrectomy with ILM stripping tended to improve both visual and anatomical outcomes.

Utility of the optical quality analysis system for decision-making in Nd: YAG laser posterior capsulotomy in patients with light posterior capsule opacity.

BACKGROUND: A prospective cohort study was performed to evaluate whether the Optical Quality Analysis System (OQAS) can serve as a valuable additional indicator for appropriate posterior capsulotomy referral. METHODS: One hundred and five eyes from 96 patients undergoing capsulotomy were divided into precapsulotomy logMAR CDVA ≤0.1 group and logMAR CDVA > 0.1 group. CDVA, and the Visual Function 14 index (VF-14) score were estimated before and 1 month after capsulotomy. The objective scattering index (OSI) value was measured by using the OQAS. Posterior capsule opacification (PCO) severity was assessed with Evaluation of PCO 2000 (EPCO 2000) software. RESULTS: In logMAR CDVA > 0.1 group, the correlations of OSI, logMAR CDVA, EPCO score and VF-14 score were very strong preoperatively. In logMAR CDVA ≤0.1 group, preoperatively, OSI was correlated with logMAR CDVA (r = 0.451), EPCO score (r = 0.789), and VF-14 score (r = 0.852). LogMAR CDVA has weak correlation with VF-14 score (r = - 0.384) and EPCO score (r = 0.566). VF-14 score was correlated with EPCO score (r = - 0.669). In the logMAR CDVA ≤0.1 group, there was no significant difference in logMAR CDVA between precapsulotomy and postcapsulotomy (P > 0.05). In the two groups, all the other optical quality parameters were significantly improved after capsulotomy (P < 0.05). In logMAR CDVA > 0.1 group, the area under the curve of the ROC of the OSI was 0.996 (P = 0.000). In logMAR CDVA ≤0.1 group, the area under the curve of the ROC of the OSI was 0.943 (P = 0.000). CONCLUSIONS: The OSI was useful for evaluating of PCO and prediction of beneficial capsulotomy. Especially for patients with slight PCO and better visual acuity, OSI is more valuable than CDVA and completely objective examination. TRIAL REGISTRATION: The study protocol was registered at the Chinese Clinical Trial Registry. Register: ChiCTR1800018842 (Registered Date: October 13th, 2018).

Stereotactic radiosurgery for clinoid meningiomas: a multi-institutional study.

PURPOSE: Resection of clinoid meningiomas can be associated with significant morbidity. Experience with stereotactic radiosurgery (SRS) for clinoid meningiomas remains limited. We studied the safety and effectiveness of SRS for clinoid meningiomas. METHODS: From twelve institutions participating in the International Radiosurgery Research Foundation, we pooled patients treated with SRS for radiologically suspected or histologically confirmed WHO grade I clinoid meningiomas. RESULTS: Two hundred seven patients (median age: 56 years) underwent SRS for clinoid meningiomas. Median treatment volume was 8.02 cm3, and 87% of tumors were immediately adjacent to the optic apparatus. The median tumor prescription dose was 12 Gy, and the median maximal dose to the anterior optic apparatus was 8.5 Gy. During a median post-SRS imaging follow-up of 51.1 months, 7% of patients experienced tumor progression. Greater margin SRS dose (HR = 0.700, p = 0.007) and pre-SRS radiotherapy (HR = 0.004, p < 0.001) were independent predictors of better tumor control. During median visual follow-up of 48 months, visual function declined in 8% of patients. Pre-SRS visual deficit (HR = 2.938, p = 0.048) and maximal radiation dose to the optic apparatus of ≥ 10 Gy (HR = 11.297, p = 0.02) independently predicted greater risk of post-SRS visual decline. Four patients experienced new post-SRS cranial nerve V neuropathy. CONCLUSIONS: SRS allows durable control of clinoid meningiomas and visual preservation in the majority of patients. Greater radiosurgical prescription dose is associated with better tumor control. Radiation dose to the optic apparatus of ≥ 10 Gy and visual impairment before the SRS increase risk of visual deterioration.

Pituitary apoplexy: how to define safe boundaries of conservative management? Early and long-term outcomes from a single UK tertiary neurosurgical unit.

OBJECTIVES: (1) Describe presentation, management and outcomes of a single-centre series of patients with pituitary apoplexy. (2) Compare early and long-term outcomes of conservative and surgical management. (3) Identify predictive factors for visual recovery. METHODS: Retrospective analysis of patients acutely managed by Sheffield's Neurosurgery over a 9-years period. Outcome comparison was made between 2 groups ('conservative' versus 'emergency') at early FU and 3 groups ('conservative' versus 'elective' versus 'emergency') at long-term FU. RESULTS: Data from 30 patients (M:F = 2.8:1; mean age: 54 years; median FU: 31.5 months) were collected. 86,7% patients presented with visual disturbances (70% acuity, 50% field, 50% diploplia). 10 (33%) patients underwent emergency surgery and further 8 underwent delayed elective surgery.At early FU, resolution rates of VA (33% versus 38%), VF (40% versus 50%) and CN deficits (71% versus 40%) were not significantly different between groups.At long-term FU, resolution of VA (80% versus 20% versus 75%) and CN deficits (67% versus 50% versus 80%) was not significantly different between groups. Most patients who underwent surgery presented with severe VA deficit (20% versus 40% versus 63%) but severity of initial deficit wasn't correlated with long-term resolution.VF recovery rates showed significant difference between groups (p = 0.027): 67% versus 0% versus 88%.Endocrine outcomes were generally poor, regardless of the management strategy.Regarding possible predictive factors, age and tumour size correlated with visual outcomes. Especially in patients treated conservatively in the acute phase, no cases of complete resolution of VA or VF deficit were recorded when tumour was higher than 35 mm. CONCLUSIONS: Good results are possible with conservative management in selected cases. Emergency surgery provides better visual outcomes. Decision-making process should be tailored to every single patient. We believe that a tumour vertical diameter >35 mm should tip the balance in favour of surgical management in presence of visual deficit.

Visual outcomes and patient satisfaction 1 and 12 months after combined implantation of extended depth of focus and trifocal intraocular lenses.

PURPOSE: To assess the 1-month and 12-month postoperative visual performance and subjective outcomes following combined implantation of an extended depth of focus (EDOF) intraocular lens (IOL) and a trifocal IOL. METHODS: The study enrolled consecutive patients undergoing refractive lens extraction or cataract surgery with combined implantation of an EDOF IOL (dominant eye) and trifocal IOL. Uncorrected (UDVA) and best-corrected (CDVA) distance visual acuities, uncorrected intermediate (UIVA) and near (UNVA) visual acuities, and subjective questionnaires were evaluated 1 month and 12 months postoperatively. RESULTS: The study enrolled 58 consecutive patients. Binocular UDVA, UIVA and UNVA were - 0.08 ± 0.07 logMAR, 0.15 ± 0.14 logMAR and 0.17 ± 0.11 logMAR at 1 month, compared to - 0.09 ± 0.06 logMAR (P = .323), 0.11 ± 0.10 logMAR (P = .030) and 0.13 ± 0.10 logMAR (P = 0.008) at 12 months. Satisfaction was high with 93.1% of patients fulfilled or more than fulfilled postoperatively, and 84.5% and 86.3% reported spectacle independence for near at the respective postoperative assessments. The mean daytime and nighttime quality of vision (QoV) scores were 9.12 ± 0.94 and 7.88 ± 1.74 at 1 month, compared to 9.24 ± 0.78 (P = .183) and 8.26 ± 1.38 (P = .043) at 12 months. CONCLUSIONS: This IOL combination provides good unaided visual acuity at 1 and 12 months postoperatively, with high functional vision and postoperative satisfaction reported at 1 and 12 months. However, a significant improvement in overall nighttime QoV at the 12 months assessment was found.

Factors for good near and distance visual outcomes of multifocal intraocular lens with inferior segmental near add.

PURPOSE: This study was conducted to investigate factors related to postoperative good near and distance visual outcomes in the Lentis Mplus LS-313 MF20 (Oculentis Gmbh, Berlin, Germany) intraocular lens (IOL)-implanted eye. METHODS: A retrospective cross-sectional study analyzed a total of 198 eyes of 198 patients. Patients with 20/20-or-more uncorrected distance visual acuity (UDVA, 5 m) and J2-or-more uncorrected near visual acuity (UNVA, 40 cm) were distributed into the good visual outcome (GVO) group (n = 96), and the remaining patients were distributed into the moderate visual outcome (MVO) group (n = 102). Differences between the two groups were compared for patient age, preoperative measurements (kappa distance, kappa angle, and pupil size), and postoperative measurements (residual sphere, cylinder, and spherical equivalent) to explore factors related to good visual outcomes after IOL implantation. RESULTS: The average age of the GVO group (56.2 years) was significantly lower than that of the MVO group (58.6 years), and the average kappa distance of the former was significantly smaller than that of the latter. However, there were no significant differences between the two groups in kappa angle and pupil size. Notably, multivariate binary regression analysis revealed that multiple factors including age, residual cylinder, and spherical equivalent were associated with good visual outcomes. Based on the receiver operating characteristic curve, cutoff values regarded as good visual outcome following cataract surgery were calculated to be - 0.38 CD in residual cylinder and - 0.32 D in residual spherical equivalent. CONCLUSIONS: Patients with implanted Lentis Mplus LS-313 MF20 IOL who are young, had small kappa distance, and had low levels of postoperative residual cylinder and spherical equivalent tended to exhibit good vision at both near and distance. These results imply that surgeons should minimize postoperative residual cylinder and spherical equivalent to provide good visual outcomes to patients with implanted Lentis Mplus LS-313 MF20 IOL.
