Clinical Grading

Purpose. We combined a clinical grading scale and swept source anterior segment OCT to describe the successful and failed CLASS. Material and Methods. 23 patients in the successful group and 17 patients in the failed group were compared in terms of the IBAGS grades and AS-OCT findings at one, three, and twelve months postoperatively. Results. The majority in the successful group presented shallow blebs (91%, 57%, and 52% at 1M, 3M, and 12M, resp.). 59% of the failed group presented no bleb (H0 E0) from the early postoperative period with the rate increasing to 88% at 3M and 100% at 12M. The scleral lake was detected in all the successful patients. The successful group showed significantly higher rates of TDM integrity (P<0.001), IF (P<0.001), and SCF (P<0.05), but there were no significant differences in the rates of microcysts between the groups (P>0.05). We found a significant decrease in the SL anteroposterior extent (P=0.003) and SL height (P<0.001) over time, with no significant correlation between the above parameters and IOP. Conclusions. The subconjunctival bleb may be a sign of the successful CLASS when it matches the AS-OCT findings of TDM integrity, maintained scleral lake, and intrascleral fluid. A validated OCT pixel intensity measurement is required to evaluate the bleb reflectivity.

Background: eye injury is often accompanied by lens damage. Aim: To evaluate the efficacy of surgical treatment of traumatic cataract with simultaneous IOL implantation in children. Material and methods: The results of surgical treatment of traumatic cataract with simultaneous IOL implantation in 62 children were analyzed: in 48 boys (77.4%) and 14 girls (22.6%) with a mean age 8.1 years. Results: visual acuity after surgery gradually increased from 0.09 to 0.22 by the end of the first month, 0.43 in 6 months and 0.47 in one year of follow-up. In 85.5% of the operated children visual acuity in the late post-op period was accounted 0.3–1.0, and in 82.2% of cases binocular vision was recovered. In the early postoperative period following complications were observed: exudative iridocyclitis — 16.1%; deposits of fibrin in the pupil — 8%; pigment deposits on surface of the IOL — 19%; secondary cataract — 12%; IOL or its haptics dislocation — 3% cases. Conclusions: Early IOL implantation during traumatic cataract surgery in children is suitable. Use of viscoelastics allows minimizing the severity of postoperative inflammation and reducing a risk of complications. Intraocular injection of Gemasa during surgery is effective to resolve hyphema, intraocular hemorrhages and fibrinoid exudate.

Clinical Grading

BACKGROUNDThe authors sought to externally validate a newly developed clinical grading scale, the Surgical Swedish ICH (SwICH) score. Patients surgically treated for spontaneous supratentorial intracerebral hemorrhage (ICH) from 2009 to 2019 in a single center in Denmark were identified. Data were retrospectively collected from patient records and neuroimaging. Surgical SwICH and ICH scores were calculated for each patient, and the validity of the Surgical SwICH was assessed and compared.OBSERVATIONSThe 126 patients included had an overall 30-day mortality rate of 23%. All patients with a Surgical SwICH score of 0 survived past one year. No patient scored the maximum Surgical SwICH score of 6. The 30-day mortality rates for Surgical SwICH scores 1, 2, 3, and 4 were 0%, 20%, 53%, and 25%, respectively (p <0.0001 for trend). Mortality rates for ICH scores 1, 2, 3, and 4 were 0%, 11%, 33%, and 76%, respectively (p <0.001 for trend). Receiver operator characteristics showed an area under curve of 0.78 for the Surgical SwICH score and 0.80 for the ICH score (p = 0.21 difference).LESSONSThe Surgical SwICH score was a good predictor of 30-day mortality in patients surgically treated for spontaneous supratentorial ICH. However, the Surgical SwICH score did not outperform the previously established ICH score in predicting 30-day mortality.

Purpose. To assess one year results and stability of the implantation of a scleral anchored intraocular lens (IOL). Design. Interventional prospective case series. Methods. Sixty eyes of 60 patients affected by either aphakia or IOL dislocation were included in this study. Patients underwent vitrectomy, scleral fixation of the IOL, and, if present, dislocated IOL removal. Patients were evaluated preoperatively and at 1, 3, 6, and 12 months after surgery by best-corrected distance visual acuity (BCVA) assessment, intraocular pressure (IOP) measurement, corneal specular microscopy, and optical coherence tomography (OCT) of both the macula and anterior segment. Results. At twelve months, mean BCVA significantly improved ( p < 0.0001 ), and none of the patients experienced a decrease of visual acuity. A 10% decrease of endothelial cell count occurred after surgery. Cystoid macular edema occurred in three patients (5%). A transient increase of intraocular pressure was noted in 7 cases (12%). At one month, horizontal and vertical IOL tilt was 1.04 ± 0.87 and 0.74 ± 0.71 degrees, respectively, and did not significantly change in the follow-up ( p > 0.05 ). None of the patients had decentration or dislocation of scleral-fixated IOL during the follow-up. Conclusion. Implantations of scleral plug fixated IOL provide good visual results, low complication rate, and excellent stability of the lens until one-year follow-up.

Background: Both pterygium ingrowth and excision determine alterations in corneal topography. The aim of this study was to evaluate the influence of pterygium removal combined with conjunctival autografts in addition to the use of human fibrin tissue glue on changes in corneal parameters as measured by 3-D swept-source anterior segment optical coherence tomography (AS-OCT) imaging. Methods: Sixteen eyes (16 patients) with pterygium that qualified for surgical treatment were enrolled in this study. Eye examination, slit lamp, and 3-D AS-OCT (CASIA 2) assessment were performed before the surgery and 7 days, 1 month, and 6 months after pterygium excision. Topographic parameters of both anterior and posterior surfaces of the cornea were analysed at each follow-up visit. Results: The gradual decrease in total astigmatism power from preoperative median 2.75 (6.15) D to 1.2 (1.1) D at 6-month follow-up (p = 0.034) was noted from the day 7 visit. Values were strongly influenced by variations of anterior cornea astigmatism. In contrast, a gradual total HOA reduction at the 1-month (from median 0.79 (1.3) D to 0.44 (0.27) D; p = 0.038) and at 6-month visits (0.25 (0.09); p = 0.001) was observed. Similarly, values were strongly influenced by variations of the anterior. Additionally, total average keratometry values increased from preoperative 44.05 (2.25) D to 44.6 (1.9) (p = 0.043) 1 month after the surgery. Conclusions: Significant steepening of the anterior cornea and a reduction in both astigmatism and HOA were observed after pterygium excision. The anterior corneal surface was an essential component of the total postoperative corneal topography values. Three-dimensional swept-source AS-OCT imaging seems to be a valuable tool for monitoring both the progression of the disease and postoperative effects in pterygium eyes.

Purpose. To assess the time course changes in corneal topographic parameters during the one-year follow-up after Descemet membrane endothelial keratoplasty (DMEK) surgery. Materials and Methods. Twenty-one patients (24 eyes) who underwent DMEK surgery were evaluated. Best corrected visual acuity (BCVA), endothelial cell count (ECC), central corneal thickness (CCT), mean keratometry (MK), mean astigmatism (MA), astigmatism asymmetry (AA), and higher-order aberration (HOA) were assessed at baseline and 1, 3, 6 and 12 months after the surgery using CASIA2 anterior segment swept-source OCT (Tomey, Japan). Results. In patients who underwent DMEK surgery, BCVA improved gradually at the subsequent visits during the 12-month follow-up. A significant reduction in ECC and CCT at the 1st month was noted, which remained stable until the 6th month postoperatively. Anterior and total MK values remained unchanged, whereas changes in posterior keratometry were noticeable until the 6th month after surgery. A significant reduction in the anterior, posterior, and total astigmatism magnitude as well as astigmatism asymmetry was observed during the first 6 months after surgery. A gradual anterior, posterior, and total HOA decrease was documented until the 12th month after surgery. Negative correlations between baseline values of CCT, MK, MA, AA, and HOA and postoperative variations in those parameters at consecutive follow-up time points were observed. Accordingly, negative correlations between baseline CCT and postoperative changes in corneal topographic parameters after surgery were found. Conclusion. The stabilization of most corneal topographic parameters takes place within 6 months after the procedure, whereas HOA reduction and BCVA improvement gradually occur during the first year after surgery. Preoperative values of corneal topographic parameters strongly determine their changes detected after DMEK surgery, which may suggest that early therapeutic intervention results in better visual outcomes.

Purpose: To describe a new surgical approach for the tectonic reconstruction of the anterior ocular segment and the management of scleral and conjuctival melting. Methods: Case series of patients demonstrating anterior segment anomalies, such as scleral and conjunctival melting. The anterior stromal part of a pre-cut corneal graft for Descemet’s stripping automated endothelial keratoplasty (DSAEK) was cross-linked with riboflavin and ultraviolet A irradiation and was used to cover scleral (scleral melting in a patient with necrotizing scleritis, one case) and conjuctival (dehiscence of the conjunctiva in patients with anti-glaucomatous valve exposure, two cases) areas. The endothelial part of all corneal grafts was used for DSAEK in patients with need of corneal endothelial transplantation. Results: Repair of scleral and conjuctival melting was successful in all cases. No intra- or post- operative complications occured. Visual acuity of all patients remained stable during the follow up period. One year postoperatively the corneal graft remained in place and no signs of inflammation were evident, while all grafts were epithelialized. Conclusions: The use of cross-linked corneal graft for the tectonic reconstruction of the anterior ocular segment represents an adequate surgical approach for the management of scleral and conjuctival melting; while, at the same time it offers the advantage of using one corneal graft for two recipients.

The aim of this study is to show the result of aneurysm coiling despite the difficulty in initiating neurointervention in Nepal. It is a retrospective study where only aneurysm that has undergone coiling are taken from 2017 to 2018.A total of eleven patients (male: female = 1: 10) with aneurysm were treated with Endovascular therapy. 9 cases were ruptured aneurysm while 3 were unruptured. 5 aneurysm were located in anterior circulation while 6 were located in posterior circulation. Out of eleven cases 4 were treated by simple coiling technique, while 2 underwent balloon assisted coiling, 3 stent assisted coiling, 1 pConus assisted coiling and 1 simple coiling and stent assisted coiling. Statistical analysis showed significant correlation between fisher grading scale with mRS score (P=0.013) suggesting lower fisher grade, and improved outcome similar to the result of prospective one year follow up of Barrow Ruptured Aneurysm Trial ( BRAT) study. With limited resources aneurysm coiling was performed at ANIAS with similar results to literature.Nepal Journal of Neuroscience, Volume 15, Number 2, 2018, page: 30-35
