Introduction: Dacryocystorhinostomy (DCR) is the treatment of choice for nasolacrimal duct obstruction. Although external DCR is regarded as the gold standard, endoscopic DCR is evolving as an equally-effective alternative. Objectives To compare the success rate of treating nasolacrimal duct obstruction by endoscopic endonasal method compared to the conventional DCR surgery. Materials and methods This prospective, comparative, non-randomised study was conducted in 2009 -2010. Thirty consecutive patients undergoing endoscopic endonasal DCR (Group 1) and 30 consecutive patients undergoing external DCR (Group 2) between July 2009 and September 2010 at the oculoplasty unit of the Tilganga institute of ophthalmology were included in this study. A patent lacrimal passage on syringing and symptomatic improvement at six months after surgery was de¿ ned as a successful outcome. The intraoperative and postoperative complications were also compared. Results Our study included 31 eyes of 30 patients in Group 1 and 34 eyes of 30 patients in Group 2. The success rate for endoscopic endonasal dacryocystorhinostomy was 90.3 % (95 % con¿ dence interval 80 -100) and external dacryocystorhinostomy was 94.1 % (95 % con¿ dence interval 80 -100). The difference of surgical success among the two methods was not statistically signi¿ cant (p = 0.7). The rate of intra-operative and post-operative complications was similar in the two methods (p = 0.5). Conclusion: The short term outcomes and complication rates of endoscopic endonasal dacryocystorhinostomy and external dacryocystorhinostomy were similar.
For early diagnosis of the disease, awareness and knowledge about the modes of presentation of the disease are very important. Similarly, the ophthalmic examination of the parents and siblings with retinoblastoma should always be done to exclude the disease.
Introduction: There are many reports of endophthalmitis following Anti- VEG F use in developed countries and from India, but there are none from Nepal yet. Therefore, the aim of this study was to report the prevalence and management of acute endophthalmitis after intravitreal injection of bevacizumab.Methods: This is a clinical, retrospective, non-comparative study, performed in Tilganga Institute of Ophthalmology, Kathmandu, Nepal from Jan 2015 till Dec 2016. All consecutive cases of intravitreal 1.25 mg of bevacizumab injections during the study period were collected from Bevacizumab registry of the operation theatre. A total number of endophthalmitis, following intravitreal bevacizumab injections were collected from Endophthalmitis registry. The statistical analysis was carried out by SPSS for percentage calculation and its 95% Confidence Interval (CI) calculation.Results: There were 4182 injections performed during the study period for various retinal conditions. Two eyes of two patients with acute postoperative endophthalmitis were identified in the first week following intravitreal injections of 1.25 mg bevacizumab among a total of 4128 injections with a prevalence of 0.048% (95% CI: 0.00 to 0.12.).Conclusions: The prevalence of acute endophthalmitis following intravitreal Bevacizumab in our retrospective series was 0.048% and was comparable with the other studies conducted elsewhere. Acute post-injection endophthalmitis following intravitreal bevacizumab can result in severe loss of vision. Therefore prompt recognition and treatment are important part of its management in such patients.
Background: Inherited macular dystrophies constitute a group of diseases characterized by bilateral central visual loss with symmetrical macular abnormalities usually presenting in the first two decades of life. The aim of this study were to find out the demographic characteristics and disease pattern of inherited retinal dystrophies in subjects attending retina outpatient department in a tertiary care center. Methods: An observational study among twenty-six participants diagnosed as macular dystrophy visiting a tertiary care centre in Nepal, during January 2018 to June 2018 were included in the study. Detailed history, slit lamp examination, dilated fundus examination, coloured fundus photography, full field electroretinogram, multifocal electroretinogram, automated visual field and colour vision were done. Results: A total of 52 eyes of 26 subjects were diagnosed with macular dystrophy. The male to female ratio was 1:1. The mean age of presentation was 28.38 years. Most common symptom was blurring of vision seen in 96.15%.The mean visual acuity was 0.67 log mar units in right eye and 0.71 log mar units in the left eye. The most common macular dystrophy was cone dystrophy followed by adult vitelliform macular dystrophy and Stargardts dystrophy. Conclusions: Cone dystrophy is the most common followed by Stargardt’s disease and adult vitelliform macular dystrophy. Most presented in the first two decades of life and the most common presenting symptom was blurring of vision. Keywords: Adult vitelliform macular dystrophy; best disease; cone dystrophy; macular dystrophy; occult macular dystrophy; stargardt’s disease
