Background: The objectives of study were to find out the different types of refractive errors in children between seven to fifteen years age group and the cause of uncorrected defective vision.Methods: A prospective study was designed of two thousand children aged between seven to fifteen years, attending outpatient department. Study period was one year. Consent was obtained from their guardian. Inclusion criteria were children with refractive errors. Children presenting with organic defects of ocular structures, infections, corneal opacity, cataract, choroid and retinal disorders were excluded from study. Data were collected by history taking and comprehensive ocular examination, visual tests for both near and distant vision. Refractive error assessed by cycloplegic drug with one percent Homatropine eye drops, by streak retinoscopy. Objective refraction were carried out and documented. Subjective refraction was done after one week. Both BCVA and uncorrected refractive errors were ascertained and recorded.Results: Out of two thousand children examined, myopic = 34%, hypermetropic = 11%, and astigmatic = 55%. M: F = 900:1000. Study showed headache as the commonest symptom. 17% of the patients had positive family history. Correctable errors constitute 91% of the total cases.Conclusions: Myopic astigmatism was found to be the most frequent refractive error in children. Mass screening is required for early diagnosis of refractive error. Prescribing corrective glasses for children with refractive errors at an early age will prevent childhood morbidity.

Background: Ocular trauma is a well-known cause of blindness and visual impairment and in industrialised nations it has become the reason for extended hospitalization of ophthalmologic patients. Anually, there are in excess of 2 million cases of ocular trauma, with more than 40,000 individuals sustaining significant visual impairment on a permanent basis. The aim of the present study was to study the pattern of ocular involvement in variety of road traffic accidents, attending the emergency department of Gauhati Medical College and Hospitals; analyse and correlate various factors playing roles in etiology and evaluate the final visual outcome. Methods: The study was conducted at a tertiary care centre in which retrospective analysis of 500 cases, who sustained injury involving any part of eye due to road traffic accidents attending emergency department from 1st January 2014 to 31st December 2016, was performed. Results: The predominant age group was between 21-30 years of age with males (75.2%) dominating over female (24.8%). Lid injury in the form of abrasions, lacerations, oedema to full thickness tear, is the commonest presentation in majority of the studies. RTA is more common in rainy and winter months and during the daytime. Two (2) wheelers is the common type of vehicle involved. Final visual outcome in the present study is good and comparable to other studies. Conclusions: Driving under the influence of alcohol is an important etiology in Northeast India. A significant section of the patients were driving two-wheelers and not following the safety precautions as advised, which calls for rigorous implementation of traffic rules. Last but not the least, it is often said that the prevention is the best way to minimise such unwanted events. Public sensitisation, strict adherence to traffic rules and improved roads are some of the few steps that can go a long way to reduce such events.

BACKGROUND Corneal transplantation or grafting is an operation in which abnormal corneal host tissue is replaced by healthy donor cornea. According to the World Health Organization (WHO), corneal diseases are among the major causes of vision loss and blindness in the world today after cataract and glaucoma. The aim of the study is to-1. Evaluate the different aetiology of corneal opacity including active infective aetiology as indicated for penetrating keratoplasty. 2. Determine the clinical outcome of penetrating keratoplasty in relation to graft survival, graft rejection and peri-operative complications in different aetiology groups. 3. Determine the final visual outcome. MATERIALS AND METHODS Candidates for keratoplasty were selected from-1. Eye Bank of Regional Institute of Ophthalmology (R.I.O). 2. R.I.O OPD. The study period was from September 2014 to August 2015. 30 cases were taken in the study. Descriptive statistics were applied to analyse the data wherever necessary. RESULTS 34.6±19.73 yrs. (mean±SD) was the mean age at which transplants were done in the study. Out of total 30 cases, 13 (43.33%) and 17 (56.66%) were male and female, respectively. The different indications for penetrating keratoplasty are-Post ulcer corneal opacity in 14 cases (46.66%), posttraumatic corneal opacity 9 cases (30%), pseudophakic bullous keratopathy 4 cases (13.33%), corneal dystrophy in 2 cases (6.66%) and non-healing corneal ulcer in 1 case (3.33%). 16 cases (53.33%) showed clear graft till the last follow up while 11 (33.33%) cases showed partially clear graft resulting in improved visual outcome while 3 cases (10.00%) of the grafts were opaque due to graft failure. CONCLUSION The major indications for penetrating keratoplasty in this part of the world are post ulcer and posttraumatic corneal opacity and majority of them are illiterate agricultural workers who failed to get adequate treatment on time. Graft survival rate is high, which can be attributed to the gradual improvement in all the aspects of penetrating keratoplasty, be it the improved viewing system, effective medications to counter complications and better understanding of corneal physiology.
