Abstract

Background: This study was conducted to evaluate the visual field changes in tubercular patients on anti-tubercular therapy and to assess the reversibility of these changes after the discontinuation therapy. Materials and Methods: This study was conducted as a prospective analytical study at tertiary care centres in Bhopal and Jabalpur on all newly detected tuberculosis patients. Ocular history, relevant history was recorded and detailed ocular examination was done at the time of presentation, before initiating ATT. All the patients were followed up periodically till the cessation of treatment and three months thereafter. Results: A total of 40 cases of newly diagnosed tuberculosis were registered with mean age of 38.4±13.99 years. We documented significant deterioration in visual acuity after 3 months of initiation of therapy. Once the ATT was stopped, the improvement in visual acuity was statistically significant 3 months after the cessation of ATT as compared to visual acuity 3 months after initiation of ATT (p Conclusion: Ethambutol, even in recommended dose according to DOTS, has been associated with ocular toxicity which manifests in the form of painless progressive loss of vision, color vision defects and visual field defects. Though these changes are usually reversible, few patients have irreversible damage. Thus, patients receiving ethambutol must be explained regarding these effects and followed up periodically.   Keywords: ATT, Ethambutol, Visual field, Visual acuity, Color vison, Reversible.

Abstract

Background: The present study aimed to study the effectiveness of B scan in assessing the posterior segment in patients with ocular trauma, so that further treatment plan can be decided and prognosis can be improved. Materials and Methods: The study was conducted as a cross-sectional study at tertiary care centre during the study period of 1 year on 42 patients presenting with history of ocular trauma. Patients were subjected to detailed history and ocular examination followed by B scan ultrasonography for ruling out posterior segment pathology. Results: Mean age of 42.7±20.2 years and 45.2% patients belonged to 41 to 60 years of age. About 54.8% cases were females. About 50% cases had one or the other posterior segment finding. Retinal detachment followed by vitreous hemorrhage were the most common findings, observed in 19% and 11.9% cases respectively. Avulsion of optic nerve was the least common finding (2.4%). Conclusion: B scan ultrasonography plays an important role in management of patients with ocular trauma for the detection of hidden posterior segment lesions. B scan must be performed routinely in all the cases of ocular trauma for early diagnosis and appropriate management of each case and to reduce the ocular morbidities.   Keywords: B scan, Ocular trauma, Intervention, Management, Ultrasonography, Posterior segment, Retinal detachment, Vitreous hemorrhage.

Abstract

The prospective study was carried out at Netaji Subhash Chandra Bose, medical college, Jabalpur, from 2017-2020, on 30 recipients, who underwent penetrating keratoplasty. The results of the surgery were studied prospectively over a period of 6 months, with follow up at 7 days, 1 month, month and 6 months. Study design: Longitudinal follow up. In our study, penetrating keratoplasty done for optical indications (67%) resulted in fairly good visual outcome, compared to those done for therapeutic indications (23%). The most common complication was corneal vascularisation (56%), and least common was secondary glaucoma (6.66%).   Keywords: Penetrating keratoplasty, Optical therapeutic.
