Abstract
OBJECTIVES The purpose of the study is as follows: To evaluate the dental and skeletal changes of the AdvanSync 2 appliance.To evaluate the soft tissue changes of the AdvanSync 2 appliance using photometric analysis. METHODS The sample size consisted of 15 patients who reported to the Department of Orthodontics, seeking fixed orthodontic treatment. The effects of the AdvanSync 2 appliance were measured at two intervals. RESULTS After the nine months, P values were observed to be less than 0.5, therefore statistically significant for parameters such as Sella-Nasion-Point A (SNA), Condylion-Point A (CO-A), University of Witwatersrand, Condylion-Gnathion (C0-Gn), point A-Nasion-Point B (ANB), Upper incisor-Point A (UI-A) (degree), LI-B (mm), Lower lip to Esthetic plane (LL-E plane), nasolabial angle, mentolabial angle, facial angle, and L lip to the chin. P values were however observed to be greater than 0.5, therefore statistically insignificant for parameters such as sella-Nasion-Point B (SNB), Condylion -gonion (C0-Go), UI A (mm), LI B (mm), UL-EPL, H LINE, Frankfurt mandibular plane (FMA), nose tip angle, nasofrontal angle, nasomental angle, upper lip angle, and U lip to the chin. CONCLUSIONS AdvanSync 2 appliance brought about a change in Class II malocclusions through Co-Gn, Co-Go, ANB, FMA, UI-A (degree), UI A (linear) LI B (linear), Upper lip to Esthetic plane, LL-E plane, Holdaway LINE, nose tip angle, nasolabial angle, mentolabial angle, nasofrontal angle, nasomental angle, facial angle, upper lip angle, U lip to chin, L lip to the chin after nine months of appliance delivery. MAIN POINTS AdvanSync 2 normalized class II by an increase in the length and body of the mandible.AdvanSync 2 has a restraining effect on the growth of the maxilla.AdvanSync 2 brings about positive soft tissue changes.The major disadvantage is the proclination of the lower incisors.

Abstract
Purpose To report a case of bilateral acute necrotising retinitis due to cytomegalovirus infection (CMV) in an Asian Indian infant. Observations An Asian Indian infant born with a birth weight of 1000 g at 26 week of gestation acquired cytomegalovirus infection from repeated blood transfusion for anemia. During the routine course of ROP screening, both eyes were detected with Type 1 ROP (stage 3 in zone 1 with plus disease) and treated with laser photoablation at 39 + 2 weeks post menstrual age. The disease responded to the laser and showed signs of regression. Four weeks after laser therapy (PMA 43 + 3 weeks), both eyes presented with vitritis, inferior vitreous condensation and white lesions in the lower nasal retina and temporal retina overlying the lasered retinal bed associated with white fluffy hemorrhagic lesions resembling necrotising retinitis. As the infant was seropositive for CMV earlier, Necrotising retinitis due to CMV was suspected. The CMV DNA was repeated and was detected in serum. Infant was treated with anti-CMV medication (oral valgancyclovir) for six weeks. The retinal lesions resolved completely. Conclusion and Importance Bilateral acute necrotising retinitis may present in an infant on post lasered retina as early as 16 weeks after birth. CMV may also present as acute necrotising retinitis in unusual cases therefore high index of suspicion and early management can result in a successful outcome.

Abstract
A 36-year-old female presented with the complaints of pain, photophobia, redness, and sudden diminution of vision in both the eyes following topiramate for migraine treatment. On examination, there was panuveitis with angle-closure glaucoma in both the eyes with fibrinous exudate with pigments in the anterior chamber of the left eye. B scan revealed increased choroidal thickness in both the eyes. Serial anterior segment optical coherence tomography scans were done in the left eye to demonstrate the gradual resolution of the fibrin material from the anterior chamber. There was complete resolution of inflammation in both eyes following discontinuation of topiramate and treatment with systemic and topical steroids. There was an improvement in visual acuity in the left eye following complicated cataract surgery.

Abstract
The purpose of this study was to demonstrate the usefulness of endoilluminator in pediatric cataract with hazy corneas. We describe a series of three cases of pediatric cataract where visualization of intraocular structures was inadequate under the operating microscope. The endoilluminator was held at the limbus with light directed obliquely to visualize the details of intraocular structures against the hazy cornea using oblique illumination. It allowed structures behind the hazy cornea to be seen with ease. A simple modification in surgical procedure of pediatric cataract using an endoilluminator helps in better visualization of intraocular structures in difficult situations.

Abstract
PURPOSE The aim of our study was to share our experience with anti-vascular endothelial growth factor (anti-VEGF) injections in the treatment of neovascular age-related macular degeneration (nAMD) in a real-world setting. DESIGN A retrospective, observational study. METHODS Patients of Indian origin with nAMD receiving anti-VEGF with a minimum follow-up of 12 months were enrolled in this study. In group 1, patients were treated on a pro re nata (PRN) basis; in group 2, patients received a loading dose (3 injecti Results: Overall, we observed that 77.31% (92/119 eyes) of patients either maintained or had improved visual acuity at 12 months' follow-up. Similar visual outcome was observed in both groups. The average number of injections given in group 1 was 4.98 and in group 2 was 3.7. CDVA at 12 months was significantly correlated with type of drug molecule, CSFT at 3 and 12 months, baseline visual acuity, and CDVA at 3 months. CONCLUSIONS PRN treatment with significantly fewer injections achieved similar anatomical and functional outcomes when compared with the loading dose group. The results of this study need to be validated with a larger study group and a longer follow-up.

Abstract
Lipemia retinalis is an unusual ocular finding associated with hypertriglyceridemia. We report the case of an infant treated for retinopathy of prematurity who later developed lipemia retinalis, with triglyceride levels of 4736 mg/dl. There was a paradoxical worsening of hypertriglyceridemia with the use of medium chain triglyceride supplement. On discontinuing the supplement, the triglycerides level drastically dropped, and retinal vasculature returned to a normal hue.

Abstract
Aim: To study the relative effects of high and low fluidic parameters on endothelial cell density (ECD), central corneal thickness (CCT), and central macular thickness (CMT) after phacoemulsification with torsional ultrasound. Settings and Design: Prospective, randomized clinical trial based on a tertiary eye hospital. Subjects and Methods: The study included 65 patients in each group. Patients were randomized to either the high or the low flow group using a computerized random number table. The study was patient and examiner masked. All patients underwent phacoemulsification with torsional ultrasound. Visual acuity, ECD, CCT, and CMT were measured for all patients preoperatively at 2 weeks and 6 weeks postoperatively. Statistical Analysis Used: The Shapiro–Wilks test was used to assess the normality of the data. Mann–Whitney U-test with the P value set at 0.05 was used to compare the two groups. Results: Cumulative dissipated energy was significantly higher in the low flow group (16.44 ± 9.07 vs. 11.74 ± 6.68; P = 0.002). No statistically significant difference was noted between the two groups in the ECD, CCT, CMT, or corrected distance visual acuity at the end of 6 weeks. Conclusions: No significant difference was noted in the postoperative outcome between high and low flow groups. Parameters can be modified to suit the surgeon's preference, as both high and low flow parameters were found to have comparable postoperative outcomes.

Abstract
Upbeat nystagmus is usually a central vestibular nystagmus attributable to structural brainstem or cerebellar lesions. Adult-onset upbeat nystagmus calls for a thorough neurological evaluation. In children, however, it can occur as a transient phenomenon in healthy neonates or as a sensory form of nystagmus that usually transforms into horizontal nystagmus by 2 years of age. We report the case of 3.5-year-old boy with upbeat nystagmus. His ocular examination was within normal limits. Neurological evaluation was normal. Optical coherence tomography testing and Electroretinogram confirmed cone dysfunction. Over the next 6 months the upbeat nystagmus converted to horizontal nystagmus.

AIM To evaluate the rapidity and amount of separation of four different types of separators (i.e. Elastomeric separators, Dumbbell separators, Kesling springs and NEET springs) and also the percentage of loss of these separators. MATERIALS AND METHODS The separating effect of 4 different types of separators (i.e. Elastomeric separators, Dumbbell separators, Kesling springs and NEET springs) were assessed for 3 days, and the separated space between molars and premolars were noted separately for three consecutive days. The number and types of lost separators were recorded at the same time. The amount of separation between molars and 2(nd) premolar in each quadrant was measured separately with a leaf gauge (sensitivity 5/100mm) and noted on each day. RESULTS Dumbbell separators proved to be the fastest in producing separation and they produced consistently greater amount of separation on all three days. CONCLUSIONS The Dumbbell separator would be ideal for situations where in rapid separation is needed, and also in cases where in the patient comes with the loss of separators.

Abstract
BACKGROUND Tuberculosis (TB) is a major public health problem in India. Several studies carried out in India have shown alcoholism as a risk factor for tuberculosis mortality, factor for default in TB and reason for non-compliance under the Revised National Tuberculosis Control Program (RNTCP). The aim of this study was to assess the prevalence, pattern and associated factors of alcohol use among tuberculosis patients in Udupi taluk, Karnataka, India. METHODS A cross-sectional study was conducted with the complete enumeration of all the cases undergoing Directly Observed Treatment Short-course (DOTS) treatment in Primary Health Centre and Community Health Centre of Udupi taluk from March to April 2013. Interview was conducted to obtain the socio-demographic and health information and participants were screened using WHO developed Alcohol Use Disorders Identification Test (AUDIT) for alcohol use. RESULTS Out of 123 participants, 78% were males, 86.2% were Hindu, 79.7% were married and 88.6% were from low socio-economic status. About 20.3% (n=25) participants were alcoholic. Among them, 44% were low risk drinkers, 32% were hazardous drinkers, 4% were harmful drinkers and 20% were alcohol dependent. Age, sex, occupation, tobacco use, perceived health status and discrimination due to tuberculosis positive status were significantly associated with alcohol use. On logistic regression sex, tobacco use, perceived health status and facing discrimination due infection with tuberculosis were found to be factors associated with alcohol use. CONCLUSIONS This study found a high prevalence of alcoholism among tuberculosis patients which is of concern and has to be addressed.

Abstract
Background Understanding the changes that occur in the choroid is of paramount importance in various uveitis entities. B-scan ultrasonography and indocyanine green angiography can be used to study choroid. Currently, spectral-domain optical coherence tomography is used as the standard noninvasive technique to study the choroid by enhanced depth imaging. Our aim was to study the structural visibility of the choroid using spectral-domain optical coherence tomography in the same area of interest in patients with uveitis with posterior segment manifestations using conventional, enhanced depth imaging (EDI), and combined depth imaging (CDI) techniques. Results Fifty-eight (58) eyes of 48 patients between age group 9 and 82 years were confirmed cases of uveitis. Out of the 48 patients, 21 (43.75%) were males while 27 (56.25%) were females. Sixteen eyes (27.59%) had intermediate uveitis, 33 (56.9%) had posterior uveitis, and 9 eyes (15.51%) had panuveitis. For posterior vitreous, there was substantial agreement for all the three groups (kappa value of 0.77, 0.73, and 0.72 in groups 1, 2, and 3, respectively). For vitreo retinal interface and inner choroid, there was perfect interobserver agreement, and for outer choroid, there was substantial to almost perfect interobserver agreement (kappa value of 0.71, 0.81, and 0.86 in groups 1, 2, and 3, respectively). Chi-squared test was done to compare the three groups. The method of scanning had a significant effect on the visualization of posterior vitreous and the outer choroid (p < 0.01) and did not have an effect on the visualization of vitreoretinal interface, inner retina, outer retina, and inner choroidal layers (p > 0.05). Conclusion The CDI technique alone might provide a good structural visibility compared to normal and EDI scanning done separately in patients with uveitis with posterior segment pathology. CDI OCT technique is thus able to visualize all posterior structures in a single image in patients with uveitis with posterior segment manifestations.

Abstract
Keratoconus is a progressive non-inflammatory thinning of the cornea that induces myopia and irregular astigmatism and decreases the quality of vision due to monocular diplopia, halos, or ghost images. Keratoconus patients unfit for corneal procedures and intolerant to refractive correction by spectacles or contact lenses have been implanted toric posterior chamber phakic intraocular lenses (PC pIOLs) alone or combined with other surgical procedures to correct the refractive errors associated with keratoconus as an off label procedure with special informed consent from the patients. Several reports attest to the safety and efficacy of the procedure, though the associated corneal higher order aberrations would have an impact on the final visual quality.

Abstract
UNLABELLED Phaco chop is the preferred technique for many phaco surgeons. A critical step in chopping is the surgeon's ability to impale the nucleus in the middle of the core endonucleus, which can be challenging. We describe a clinical sign in the phaco chop technique to help surgeons identify the center of the endonucleus without estimating the nucleus thickness. This technique uses the morphological structure of the lens and the lens fiber orientation to precisely gauge the depth at which the surgeon should impale and hold the nucleus for effective chopping.

Abstract
Background We are reporting a case of granulomatous panuveitis in the right eye following penetrating injury to the left eye. Findings A 34-year-old female was diagnosed to have sympathetic ophthalmia on treatment with systemic steroids. Vision did not improve in spite of aggressive systemic steroid therapy. On examination, patient had large retinal pigment epithelial rip nasal to the disc with exudative retinal detachment which was documented with FFA, ICG, and OCT. RPE rip is responsible for the persistent exudative retinal detachment in the right eye. Conclusions RPE rip can cause decreased vision due to persistence of retinal detachment in a case of sympathetic ophthalmia.

Abstract
Werner's syndrome (WS) is a rare autosomal recessive disorder with multisystem manifestations of premature aging from the second decade of life. Cataract is one of the features of WS. Cataract surgery is complicated with postoperative wound dehiscence and bullous keratopathy when the surgery is done by intracapsular or conventional extracapsular method. We report the short-term result of phacoemulsification and Neodymimum Yettrium-Aluminum-Garnet laser (Nd YAG) capsulotomy in a case of WS with bilateral cataracts. Postoperatively and post capsulotomy, there was no change in the endothelial cell morphology. There was an 8.6% decrease in endothelial cell count at the end of 15 months postoperatively and 11 months post YAG capsulotomy. This decrease is within the acceptable range of cell loss after phacoemulsification and YAG capsulotomy. To the best of our knowledge, this is the first reported case of YAG laser capsulotomy in WS.

Abstract
PURPOSE To investigate macular changes in acute retinopathy of prematurity (ROP). METHODS Fifty-four premature infants with ROP and 20 controls underwent routine ROP screening with indirect ophthalmoscopy and imaging. A tabletop spectral domain optical coherence tomography (SD-OCT) scanner (Spectralis; Heidelberg Engineering, Heidelberg, Germany) was converted into a handheld device to image infants in the office sans sedation. RESULTS SD-OCT images were obtained in all infants in the office. On SD-OCT, 23 of 79 eyes (29.1%) with stage 2 ROP showed abnormal foveal changes despite clinically normal foveae. Of the 23 eyes, 2 distinct patterns of foveal involvement were observed: "pattern A," which was characterized by dome-shaped foveal elevation and cystoid spaces with highly reflective intervening vertical septae, and "pattern B," which was characterized by preservation of the foveal depression with fewer intraretinal cystoid spaces. These patterns were seen in 12 (52.2%) and 11 (47.8%) eyes, respectively. All eyes (100%) belonging to stage 1 ROP (27) and the normal group (40) had no abnormal SD-OCT changes. The mean central foveal thickness was 156.9 ± 28.3 μm, 206.5 ± 98.7 μm, and 135.9 ± 17.6 μm for stage 1, 2, and normal eyes, respectively (P < 0.001). Nineteen of the 23 eyes underwent serial imaging at 52 weeks' postmenstrual age (PMA), and all of them revealed normalization of foveal contours at this visit. CONCLUSIONS SD-OCT changes of the macula in mild ROP have not been previously described. Our method reveals that infants may be imaged supine and unanesthetized in the office. We hypothesize that these transient foveal changes at the critical time of fovealization in premature infants may influence their visual acuity in the adult life.

Abstract
OBJECTIVE To report a case of acute zonal occult outer retinopathy (AZOOR) caused by Polycythemia and increased levels of Factor VIIIC. DESIGN Case Report - Interventional. METHODS We present a 23 year old male with blurring of vision and loss of lower visual fields in both eyes. Ocular examination suggested the possibility of AZOOR that was confirmed with Fluorescein Angiogram, Visual fields and Electroretinogram. Laboratory work up revealed polycythemia with increased Factor VIIIC. He was treated for the same. RESULTS Ocular symptoms improved within 24 hours of treatment with venesection and asprin. CONCLUSIONS Polycythemia vera and increased factor VIIIC levels, both venous thromboembolic risk factors are treatable causes of AZOOR.

Abstract
To report the efficacy of a blue fixation target to record Pattern Visual Evoked Potential (PVEP) in optic neuropathy subjects with acquired red-green (RG) color vision deficit. This is a prospective, nonrandomized, cross-sectional, case series of twenty-nine eyes of twenty-two subjects with optic neuropathy of various etiologies. All underwent detailed ophthalmological evaluation, imaging, and PVEP. PVEP was done with 120' and 60' checker stimulus to both red and blue fixation targets. The amplitude and latency of P100 waveform was the measured outcome. The PVEP recording to blue fixation target was found to be superior to the red fixation target in cases of RG color vision deficits with both 120' (P = 0.01) and 60' (P = 0.037) check sizes. In the cases in which the PVEP was recordable with both red and blue fixation targets, the P100 amplitude and latency parameters were comparable and showed positive correlation. Defective fixation and abnormal RG color vision also affected PVEP recordability to the red fixation target. Good fixation is essential for obtaining a reliable PVEP recording. In this study, the authors have used a blue fixation target as a method to ensure fixation in patients with RG color deficits and have demonstrated the ability to get good recordings in cases with otherwise flat recording. The use of alternate colored target or achromatic fixation target should be considered to ensure good central fixation so as to yield better quality recording that possibly correlates better with the functioning of the optic pathway in subjects with abnormal color vision.

Abstract
Context In contact lens-intolerant keratoconus patients, intrastromal placement of Intacs is becoming a promising new modality of treatment. Aims To study the safety and efficacy of implantation of microthin corneal inserts (Intacs) in Asian-Indian keratoconus patients. Settings and Design Retrospective interventional case series, in the cornea and refractive surgery service, at a tertiary care eye hospital in South India, between May 2006 and July 2007. Materials and Methods Intacs (Addition Technology, USA) were successfully implanted by mechanically creating tunnels, in 12 eyes of 12 keratoconus patients, who were contact lens-intolerant. The patients (mean age 25.58 years, nine male and three female) had a minimum follow-up of six months. Five patients had severe keratoconus (mean K > 53 D) and nine had central cones. Results All patients improved or retained visual acuity. The uncorrected visual acuity (UCVA) improved from a mean value of 0.06, (SD ± 0.08) to 0.19 postoperatively (SD± 0.15) (P= 0.01). The change in mean best corrected visual acuity (BCVA) was from 0.51, (SD ± 0.24), to 0.69, (SD ±0.00) (P = 0.01) postoperatively. The average central keratometry reading was 52.55 D. The change in mean K from 52.84 to 49.16 and 49.15 at one and six months respectively, was statistically significant. We did not have any major intra- or early postoperative complications. Eight of 12 eyes became contact lens-tolerant post-surgery. Conclusion The procedure of Intacs implantation appears to be safe and effective in a small group of Indian population at an intermediate follow-up.

Abstract
We present 2 cases that came to our institute for refractive surgery and were discovered to have serious systemic conditions requiring immediate intervention. On examination, prolactinoma of the pituitary gland was seen in one patient and multiple sclerosis was diagnosed in the other patient. Prompt treatment of the conditions led to improvement in the neuro-ophthalmic disorders. We recommend a thorough physical evaluation of patients having an ophthalmic examination.

Abstract
PURPOSE To report ocular manifestations associated with chikungunya. DESIGN Retrospective, nonrandomized, observational case series. PARTICIPANTS Nine chikungunya patients with ocular involvement. METHODS All patients with chikungunya infection presenting with ocular complaints from September 2006 to October 2006 were included in the study. The infection was confirmed by demonstration of chikungunya immunoglobulin M antibody in sera of all patients. All patients underwent an ophthalmic examination including fundus photography, fundus fluorescein angiography, confocal microscopy of keratic precipitates, and optical coherence tomography. Positive ocular changes were recorded and tabulated. MAIN OUTCOME MEASURES Characteristics, frequency, and locations of ocular lesions found in the participants. RESULTS There were 9 patients with ocular lesions; 1 had nodular episcleritis, 5 presented with acute iridocyclitis, and 3 had retinitis. Four to 12 weeks before the development of ocular manifestations, all of these patients had fever. Although there were no specific changes of iridocyclitis that were diagnostic of the fever, the retinal changes were consistent with viral retinitis. All patients recovered from the infection with relatively good vision. CONCLUSION It appears that iridocyclitis and retinitis are the most common ocular manifestations associated with chikungunya, with a typically benign clinical course. Less frequent ocular lesions include episcleritis. All the patients responded well to the treatment with preservation of good vision. To the best of our knowledge, similar ocular manifestations associated with chikungunya infection have not been reported. In the differential diagnosis of iridocyclitis and retinitis with features suggestive of a viral infection, the entity of chikungunya-associated ocular changes should be considered in the regions affected by the epidemic.

Abstract
PURPOSE To investigate clinical, anatomic, and electrophysiologic response after single intravitreal injection of bevacizumab for macular edema attributable to retinal vein occlusion. DESIGN Prospective nonrandomized, interventional case series. METHODS Twenty-one patients with macular edema attributable to vein occlusion received intravitreal injection of bevacizumab 1.25 mg. Nine patients had central retinal vein occlusion (CRVO), and 12 patients had branch retinal vein occlusion (BRVO). Complete ophthalmic examination including optical coherence tomography (OCT) was done at baseline and follow-up visits. Fifteen patients underwent fluorescein angiography at baseline. Selected patients underwent electroretinography (ERG) and visual evoked potential (VEP) at baseline and follow-up. Follow-up was for 12 weeks. RESULTS At baseline, mean visual acuity was 20/381 (median, 20/400) and showed improvement to mean 20/135 (median, 20/60) after one month, (P = .001). At 12 weeks, mean visual acuity was 20/178 (median, 20/80) (P = .001). The mean central retinal thickness (CRT) was 647.81 microm (median, 609.00 microm) at baseline and decreased to mean 293.43 microm (median, 222.00 microm) at one month (P = .001). At 12 weeks, mean CRT was 320.90 mum (median, 280.00 microm) (P = .001). ERG and VEP showed no worsening of the waveforms. There was no significant difference in the visual outcome between the BRVO and CRVO groups. CONCLUSION Intravitreal injection of bevacizumab appears to result in significant short-term improvement of visual acuity and macular edema secondary to vein occlusion. The present report confirms the previous studies. No ocular toxicity or adverse effects were observed. However, prospective, randomized, controlled long-term studies are required with an adequate number of patients.

Abstract
We report the confocal microscopic findings in a case of interlamellar stromal keratopathy induced by elevated intraocular pressure (IOP) after laser in situ keratomileusis (LASIK). In vivo confocal microscopy showed swollen and enlarged cellular structures and the presence of microlacunae separating the stromal collagen lamellae. Inflammatory mononuclear cells and granulocytes typically seen in patients with diffuse lamellar keratitis (DLK) were absent. Stopping the topical steroids with concurrent lowering of the IOP resulted in improvement in the uncorrected and best corrected visual acuities and was associated with resolution of the corneal findings. In vivo confocal microscopy is a useful tool to study interlamellar stromal keratopathy induced by elevated IOP after LASIK in humans and the response to treatment and to differentiate interlamellar stromal keratopathy from DLK.
