Results of intraocular lens implantation with capsular tension ring in subluxated crystalline or cataractous lenses in children

Purpose : To evaluate the outcome of intraocular lens (IOL) implantation using capsular tension ring (CTR) in subluxated crystalline or cataractous lenses in children. Setting : Tertiary care setting Materials and Methods : We prospectively studied 18 eyes of 15 children with subluxation of crystalline or cataractous lenses between 90° up to 210° after phacoemulsification, CTR and IOL implantation. Each child was examined for IOL centration, zonular dehiscence and posterior capsular opacification (PCO). Results : Age of the patient ranged between five to 15 years. Out of 18 eyes, seven had traumatic and 11 had spontaneous subluxation of crystalline or cataractous lens. Phacoemulsification was successfully performed with CTR implantation in the capsular bag. Intraoperative zonular dialysis occurred in two eyes. Anterior vitrectomy was performed in six eyes to manage vitreous prolapse. IOL implanted was polymethyl methacrylate (PMMA) in eight eyes, hydrophobic acrylic in seven and hydrophilic acrylic in three. Follow-up ranged from 24 months to 72 months. Sixteen eyes had a best corrected visual acuity of 20/40 or better. Nine eyes developed significant PCO and were managed with Neodymium Yttrium Aluminum Garnet (Nd:YAG) laser posterior capsulotomy. One eye with acrylic IOL in the capsular bag had IOL dislocation after two years which was managed with vitrectomy and secondary trans-scleral fixation of IOL. Conclusions : Phacoaspiration with CTR implantation makes capsular bag IOL fixation possible in most of the eyes with subluxated crystalline or cataractous lenses. PCO still remains a challenge in children with successful phacoaspiration with CTR implantatio

Impact of COVID-19-related lockdown on retinal disorders treated with intravitreal injections

PURPOSE: To study functional changes in vision and morphological changes on optical coherence tomography (OCT) scans in patients where intravitreal therapy (IVT) with injections has been delayed due to COVID-19 pandemic lockdown. METHODS: Retrospective cross-sectional study included 77 eyes with the diagnosis of exudative age-related macular degeneration (eAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO), regularly receiving IVT with anti-vascular endothelial growth factor (Anti-VEGF) injections or dexamethasone implant and were not able to receive the injections as intended due to lockdown. Best-corrected visual acuity (BCVA), central foveal thickness (CFT), and qualitative morphological features on OCT were analyzed pre- and post-therapy break off. RESULTS: The mean duration of IVT break-off was 57 days. Mean BCVA logarithm of minimum angle of resolution (logMAR) worsened from 0.33 (20/42) to 0.35 (40/44) (P = 0.02) and mean CFT increased from 297.90 μm to 402.16 μm (P < 0.01), from pretherapy break-off to return visit. Worsening of the visual acuity was seen across all the three disease cohorts, significantly more in the eyes with eAMD. CONCLUSION: Marginal decline in the visual acuity and worsening of the OCT features were observed as a result of delay in the IVT injections of DME, eAMD and RVO patients

Role of anti-tubercular therapy in uveitis with latent/manifest tuberculosis

PURPOSE: To assess the role of anti-tubercular therapy in uveitis with latent/manifest tuberculosis (TB). DESIGN: Retrospective, interventional case series. METHODS: A total of 360 patients from uveitis clinic with following inclusion criteria were studied: 1) complete clinical records of visual acuity, slit-lamp biomicroscopic examination, intraocular pressure, complications if any, and treatment records at the baseline and at all follow-up visits; 2) a documented positive tuberculin skin test (10 mm of induration or more) at 48 to 72 hours; 3) evidence of active uveitis, i.e., cellular reaction in the anterior chamber with or without keratic precipitates, and/or active vitreous inflammation, retinal vasculitis, choroiditis, or neuroretinitis; 4) all known causes of infectious uveitis except TB and known noninfectious uveitic syndromes ruled out; and 5) a minimum one year of follow-up from the initiation of treatment. Of these, 216 patients (Group A) received four-drug anti-tubercular therapy and corticosteroids, and 144 patients (Group B) received corticosteroids alone. The main outcome measure was recurrence of inflammation after minimum six months of initiating treatment in each group. RESULTS: Recurrences reduced significantly (P < .001) in Group A (15.74%) as compared to Group B (46.53%) over a median follow-up of 24 and 31 months, respectively. The patients treated with anti-tubercular therapy with corticosteroids had decreased risk of developing recurrence of uveitis by approximately two-thirds as compared to those treated with corticosteroids alone. CONCLUSION: Addition of anti-tubercular therapy to corticosteroids in uveitis patients with latent/manifest TB led to significant reduction in recurrences of uveitis

Impact of improved neonatal care on the profile of retinopathy of prematurity in rural neonatal centers in India over a 4-year period

Purpose: To report the reduction in the incidence and severity of retinopathy of prematurity (ROP) in rural India over a 4-year period following the introduction of improved neonatal care practices. Methods: The Karnataka Internet Diagnosis of Retinopathy of Prematurity program (KIDROP), is a tele-medicine network that screens for ROP in different zones of Karnataka state in rural India. North Karnataka is the most underdeveloped and remote zone of this program and did not have any ROP screening programs before the intervention of the KIDROP in 2011. Six government and eleven private neonatal centers in this zone were screened weekly. Specific neonatal guidelines for ROP were developed and introduced in these centers. They included awareness about risk factors, oxygen regulation protocols, use of pulse oxymetry, monitoring postnatal weight gain, nutritional best practices, and management of sepsis. The incidence and severity of ROP were compared before the guidelines were introduced (Jan 2011 to Dec 2012) and after the guidelines were introduced (July 2013 to June 2015). Results: During this 4-year period, 4,167 infants were screened over 11,390 imaging sessions. The number of enrolled infants increased from 1,825 to 2,342 between the two periods (
