Purpose To investigate the efficacy of botulinum toxin injection without electromyographic guidance for the treatment of consecutive esotropia. Methods A retrospective study was performed on 49 subjects with consecutive esotropia who received botulinum toxin injection in the medial rectus muscles without the use of electromyographic guidance. Treatment was considered successful if the final ocular alignment was orthotropic or esodeviation was ≤10 prism diopters (PD) during distant fixation. Results The mean age was 15.2 ± 8.3 years. The mean esodeviation before injection was 21.8 ± 9.1 PD at distance and 21.3 ± 8.3 PD at near. The mean number of injections per patient was 1.3 ± 0.7, and 46 patients (93.9%) received two or fewer injections. At 6 months after the final injection, the mean angle of esodeviation was 7.3 ± 6.0 PD at distance and 7.5 ± 6.6 PD at near (all p<0.001), and 69.4% showed successful alignment. By multivariate analysis, an initial postoperative esodeviation of ≤18 PD at one month after exotropia surgery was considered to be a predictive factor for successful botulinum toxin injection (P = 0.007). Vertical deviation and/or ptosis occurred in 4 patients (8.2%) at two weeks after injection, which all resolved within three months. There was no recurrence of exotropia up to the final follow-up examination. Conclusion Botulinum toxin injection without electromyographic guidance is safe and effective in the treatment of consecutive esotropia without causing recurrent exotropia. Successful botulinum toxin injection is likely in patients with an initial postoperative esodeviation of 18PD or less at one month after exotropia surgery.

Purpose. To report on an improved botulinum toxin injection with conjunctival microincision for beginners, and to determine the effectiveness of botulinum toxin A (BTXA) in the treatment of patients with acute acquired comitant esotropia (AACE). Methods. Medical records of 29 AACE patients were retrospectively analyzed. BTXA was injected into the unilateral or bilateral medial rectus muscle with conjunctival microincision without electromyographic guidance. Success was defined as total horizontal deviation ≤10 prism diopters (PD) and evidence of binocular vision. Results. Twenty-nine patients were included, of whom 22 were male and 7 were female. The mean age at onset was 14.2 ± 7.4 (range, 4–34) years. The mean time from onset of AACE to injection was 18.4 ± 20.3 (range, 1–96) weeks. All patients completed at least 6 months of follow-up, and the mean follow-up after BTXA injection was 12.3 ± 4.8 months (range, 7–24 months). Neurological evaluation and brain magnetic resonance imaging (MRI) were unremarkable in all patients. The mean spherical equivalent refraction was −1.22 ± 2.85D and −0.97 ± 2.80D in the right and left eyes, respectively. Mean preinjective esotropia was 38.4 ± 18.9 PD (range, +10–+80 PD) at near and 40.2 ± 17.7 PD (range, +20–+80 PD) at far distance. The mean angle of deviation at 6 months after injection was 0.6 ± 4.1 PD (range, −3–+15 PD) at near and 3.0 ± 5.9 PD (range, 0–+20 PD) at far distance. There was significant difference in the angle of deviation at near and far fixation between pre-BTXA and post-BTXA 6 months ( p < 0.001 , p < 0.001 , resp.). There was no significant difference in the angle of deviation at near and far fixation between post-BTXA 6 months and post-BTXA at final follow-up ( p  = 0.259 and 0.326, resp.). Mean stereoacuity improved from 338 to 88 arc seconds. During the follow-up period, 5 of 29 patients had recurrent esotropia. Two patients refused all further treatment, and the other 3 patients required incisional strabismus surgery. The success rates were 86.2% (25/29) at 6 months and 82.8% (24/29) at final follow-up. Conclusion. Conjunctival microincision injection of botulinum toxin is a practical and safe method for beginners to locate an extraocular muscle, which is as effective as the traditional methods. Botulinum toxin injection can be preferred as the first-line treatment for AACE patients with potential binocular vision.

AbstractObjectiveGiven the lack of evidence on patients with medically refractory vestibular migraine, this study aimed to identify factors associated with pharmacotherapy failure and progression to botulinum toxin injection in vestibular migraine.MethodsA retrospective cohort study was conducted on definite vestibular migraine patients from September 2015 to July 2019 who completed the Dizziness Handicap Inventory at least six weeks apart..ResultsThe study comprised 47 patients (mean age = 50.2 ± 15.8 years), with a mean follow-up time of 6.0 ± 6.0 months. The mean pre-treatment Dizziness Handicap Inventory score was 57.5 ± 23.5, with a mean reduction of 17.3 ± 25.2 (p < 0.001) at last follow up. Oscillopsia (r = 0.458, p = 0.007), failure of first medication (r = 0.518, p = 0.001) and pre-treatment Dizziness Handicap Inventory question 15 (an emotional domain question) score (r = 0.364, p = 0.019) were the only variables significantly correlated with progression to botulinum toxin injection.ConclusionMotion hypersensitivity, failure of first medication, and fear of social stigmatisation suggest a decreased treatment response. These symptoms may require more aggressive treatment at an earlier stage.

Abstract Background Different surgical methods have been suggested for the correction of intermittent exotropia. Unilateral lateral rectus recession has been described as a surgical alternative for small and moderate-angle exotropia. In general, previous studies did not focus on the outcomes of unilateral lateral rectus recession in young children with intermittent exotropia. The purpose of this study is to evaluate the surgical outcomes of unilateral lateral rectus recession in the treatment of moderate-angle exotropia (≤ 25 PD (prism diopters)) in children. Methods The charts of all patients younger than 12 years of age with moderate-angle exotropia (up to 25 PD) who were operated during the years 2006–2018 were retrospectively reviewed. Fifty-eight patients underwent unilateral lateral rectus recession and had a minimum follow up of 6 months. The angle of exotropia (PD) before and after surgery and the success rate were documented. Results Mean age at surgery was 6.4 ± 1.9 (range 3.5–11.0) years. Exotropia improved from a preoperative angle of 21.4 ± 4.0 PD to 3.5 ± 5.9 PD postoperatively (p < 0.001). Success rate, defined as deviation of ≤ 10 PD, was achieved in 86.2%. There were 2 (3.4%) cases of overcorrection (consecutive esotropia). There were no intra- or postoperative complications. The mean follow-up duration after surgery was 2.3 ± 1.7 years. Conclusions In children with moderate angle exotropia, good postoperative success rate was achieved by performing unilateral lateral rectus recession.

Abstract Introduction Laparoscopic fundoplication (LF) has almost completely replaced the open procedure performed for gastroesophageal reflux disease (GERD) and hiatus hernia (HH). Several studies have suggested that long-term results with surgery for GERD are better than a medical line of management. In this retrospective study, we outline our experience with LF over 10 years. Also, we analyze the factors that would help us in better patient selection, thereby positively affecting the outcomes of surgery. Patients and Methods In this retrospective study, we identified 27 patients (14 females and 13 males) operated upon by a single surgeon from 2010 to 2020 at our institution. Out of these, 25 patients (12 females and 13 males) had GERD with type I HH and 2 (both females) had type II HH without GERD. The age range was 24 to 75 years. All patients had undergone oesophago-gastro-duodenoscopy (OGD scopy). A total of 25 patients had various degrees of esophagitis. Two patients had no esophagitis. These patients were analyzed for age, sex, symptoms, preoperative evaluation, exact procedure performed (Nissen’s vs. Toupet’s vs. cruroplasty + gastropexy), morbidity/mortality, and functional outcomes. They were also reviewed to examine the length of stay, length of procedure, complications, and recurrent symptoms on follow-up. Symptoms were assessed objectively with a score for six classical GERD symptoms preoperatively and on follow-up at 1-, 4- and 6-weeks postsurgery. Further evaluation was performed after 6 months and then annually for 2 years. Results 14 females (53%) and 13 males (48%) with a diagnosis of GERD (with type I HH) and type II HH were operated upon. The mean age was 46 years (24–75 years) and the mean body mass index (BMI) was 27 (18–32). The range of duration of the preoperative symptoms was 6 months to 2 years. The average operating time dropped from 130 minutes for the first 12 cases to 90 minutes for the last 15 cases. The mean hospital stay was 3 days (range: 2–4 days). In the immediate postoperative period, 72% (n = 18) of the patients reported improvement in the GERD symptoms, while 2 (8%) patients described heartburn (grade I, mild, daily) and 1 (4%) patient described bloating (grade I, daily). A total of 5 patients (20%) reported mild dysphagia to solids in the first 2 postoperative weeks. These symptoms settled down after 2 to 5 weeks of postoperative proton-pump inhibitor (PPI) therapy and by adjusting consistency of oral feeds. There was no conversion to open, and we observed no perioperative mortality. There were no patients who underwent redo surgeries in the series. Conclusion LF is a safe and highly effective procedure for a patient with symptoms of GERD, and it gives long-term relief from the symptoms. Stringent selection criteria are necessary to optimize the results of surgery. Experience is associated with a significant reduction of operating time.

BackgroundTo evaluate the safety and efficacy of intravitreal conbercept (IVC) injection in the treatment of retinopathy of prematurity (ROP).MethodsPatients with ROP who underwent IVC injection in Zhujiang Hospital from June 2015 to July 2016 were studied retrospectively. The primary outcome was defined as the regression of plus disease. The secondary outcomes were defined as the presence of recurrence, number of injections and the final regression of disease.ResultsA total of 48 eyes of 24 patients with ROP were included. Among them, 9 eyes of 5 patients had zone I ROP, 35 eyes of 18 patients had zone II ROP and 4 eyes of 2 patients had aggressive posterior ROP. The mean gestational age was 28.5±1.6 weeks, the mean birth weight was 1209.6±228.6 g, the mean postmenstrual age of first injection was 34.2±1.9 weeks and the mean follow-up period was 31.0±4.7 weeks. Forty of 48 eyes (83.3%) received IVC only once, and the regression of plus disease occurred at an average of 3.5±1.5 weeks after the first injection of conbercept. For eight recurrent eyes (16.7%), four eyes received a second IVC and the remaining four eyes received laser photocoagulation, and the regression of plus disease occurred in 3 weeks. No lens opacity, vitreous haemorrhage, entophthalmia or retinal detachment was observed during follow-up.ConclusionIVC injection is an effective treatment for ROP.

Abstract AimTo investigate the effect of orthokeratology (OK) lens on axial length (AL) elongation in myopia with anisometropia children.MethodsThirty-seven unilateral myopia (group 1) and fifty-nine bilateral myopia with anisometropia children were involved in this 1-year retrospective study. And bilateral myopia with anisometropia children were divided into group 2A (diopter of the lower SER eye under − 2.00D) and group 2B(diopter of the lower SER eye is equal or greater than − 2.00D). The change in AL were observed.The datas were analysed using SPSS 21.0.Results(1) In group 1, the mean baseline AL of the H eyes and L eye were 24.70 ± 0.89 mm and 23.55 ± 0.69 mm, respectively. In group 2A, the mean baseline AL of the H eyes and L eyes were 24.61 ± 0.84 mm and 24.00 ± 0.70 mm respectively. In group 2B, the mean baseline AL of the H eyes and L eyes were 25.28 ± 0.72 mm and 24.70 ± 0.74 mm. After 1 year, the change in AL of the L eyes was faster than the H eyes in group 1 and group 2A (all P<0.001).While the AL of the H eyes and L eyes had the same increased rate in group 2B. (2) The effect of controlling AL elongation of H eyes is consistent in three groups (P = 0.559).The effect of controlling AL elongation of L eyes in group 2B was better than that in group 1 and group 2A (P < 0.001). And the difference between group 1 and group 2A has no statistical significance. (3) The AL difference in H eyes and L eyes decreased from baseline 1.16 ± 0.55mm to 0.88 ± 0.68mm after 1 year in group 1.And in group 2A, the AL difference in H eyes and L eyes decreased from baseline 0.61 ± 0.34mm to 0.48 ± 0.28mm. There was statistically significant difference (all P<0.001). In group 2B, the baseline AL difference in H eyes and L eyes has no significant difference from that after 1 year (P = 0.069).ConclusionsMonocular OK lens is effective on suppression AL growth of the myopic eyes and reduce anisometropia value in unilateral myopic children. Binocular OK lenses only reduce anisometropia with the diopter of the low eye under − 2.00D. Binocular OK lenses cannot reduce anisometropia with the diopter of the low eye equal or greater than − 2.00D. Whether OK lens can reduce refractive anisometropia value is related to the spherical equivalent refractive of low refractive eye in bilateral myopia with anisometropia children after 1-year follow-up.

Purpose To evaluate in a retrospective study the long-term usefulness of red 647 nm krypton and 670 nm diode laser for transscleral contact cyclophotocoagulation (CPC) in the treatment of therapy-resistant inflammatory glaucoma. Methods The authors treated 48 eyes of 38 consecutive patients (mean age 36.8 years, range 6–81 years) with therapy-resistant inflammatory glaucoma secondary to chronic uveitis (45/48), chronic scleritis (1/48), or combined scleritis with keratouveitis (2/48) using transscleral red 647 nm Krypton or 670 nm Diode laser. All eyes had failed maximum tolerated medical therapy and 19/48 (40%) eyes also previous antiglaucoma surgery. Laser power at the scleral surface was 0.35 to 0.45 W and the application time 10 seconds each. The follow-up was 42.8± 40.0 (range 2–145) months. Results The mean preoperative intraocular pressure (IOP) of 35.6±8.1 mmHg fell to 6–21 mmHg level in 75% after one or repeated CPC. Among adult patients this was achieved in 85%, among children in 54%. More than one treatment was needed in 52%. No cases of hypotony, phthisis bulbi, or other devastating complications occurred. Conclusions Transscleral CPC using red 647 nm krypton or 670 nm diode laser is an effective and well-tolerated procedure for the treatment of therapy-resistant inflammatory glaucoma in adults. CPC can be considered before incisional antiglaucoma surgery with a shunt or antimetabolites is undertaken

Abstract Background Diagnostic importance of asymptomatic cryptococcal antigenemia is being increasingly recognized in the last few years. Recently, WHO (World Health Organization) has recommended routine screening of CrAg (cryptococcal antigen) among PLHA with CD4 ≤100/mm3, albeit this procedure is not yet adopted by many developing countries including India. Methods We conducted a prospective observational study in a large tertiary care center of North India, upon ethical clearance. Latex agglutination test was performed to assess serum CrAg levels, followed by the lumbar puncture for detection of CrAg levels in the CSF. We analyzed the prevalence and treatment outcomes of cryptococcal antigenemia among PLHA with CD4 ≤ 100 cells/mm3. Detailed clinical examination was conducted, with follow-up of upto 3 months. Multivariate analysis was performed for the estimation of risk factors. Results The mean age (years) and BMI (kg/m2) of all the participants were 41.4 ± 11.2 and 22.1 ± 2.6, respectively. Notably, the mean CD4 count (cu.mm) at the time of recruitment was 62.3 ± 20.5. Noteworthy, 62 (60.8%) of the patients were ART naïve. We found 9.8% (n = 10) of the patients were positive for serum CrAg, and only 2.9% (n = 3) had clinical features of meningitis and 6.8% (n = 7) were asymptomatic (subclinical) CrAg positive. Strikingly, 3.9% (n = 4) of the asymptomatic cryptococcal antigenemia patients were also positive for CrAg in CSF, with 1.9% (n = 2) were only serum CrAg positive, and 1 patient was lost to follow-up (Graph 1). Multivariate analysis revealed that patients with long duration of HIV (P = 0.04), headache symptoms (P = 0.004) and possessing features of meningismus (P value=0.08) are more likely to be CrAg positive. Conversely, patients on fluconazole were protective against cryptococcal antigenemia (P = 0.1) as shown in Table 1. Overall mortality observed was 11.3% among advanced HIV patients. Moreover, mortality in CrAg-positive patients was 33.3% in comparison to CrAg-negative patients who had 9% (P = 0.06) in 3-months follow-up. Conclusion Cryptococcal antigenemia is common (9.8%) among patients with CD4 count ≤100/mm3 in India. Screening for CrAg should be made routine for PLHA with CD4 count ≤100/mm3 and if required preemptive treatment to be given in this regard. Disclosures All authors: No reported disclosures.

The sliding genioplasty for cosmetic augmentation of microgenia is a common procedure performed by maxillofacial and cosmetic surgeons. There are multiple designs for this osteotomy, and multiple fixation techniques proposed, among which include wires, screws, bone plates, and pins. Likewise, there are many advantages and disadvantages to each of the designs and the fixation techniques that will be utilized according to the surgical indications and the surgeon's preference. A techique used at the Medical College of Wisconsin in Milwaukee involves fixation of the osteotomy segments with Kirschner pins placed at multiple divergent angles. This technique allows for placement of the free segments in virtually any location, and provides for a type of rigid stabilization, particularly in large anterior and vertical movements. One criticism that has been suggested with the use of Kirschner pins is the possibility of migration. This retrospective study evaluates 13 patients who underwent augmentation genioplasty, rigidly fixated with Kirschner pins. Twenty-eight total Kirschner pins were placed, with one being removed. The mean postoperative follow-up was 32 months, and the average number of pins placed was 2.15 per patient. It would appear then, from this study, that migration of Kirschner pins when used with the sliding genioplasty, is not a significant postoperative concern.
