Demographic and microbiological profile of corneal ulcer patients presenting at a tertiary healthcare center of Eastern India during the COVID era: A hospital-based cross-sectional study.

Purpose: To determine the demographic and microbiological profile involved in the causation of corneal ulcers in Eastern India during the COVID era. Method: Patients presenting with corneal ulcers fulfilling the inclusion and exclusion criteria were taken as the case. The study duration was from January 2021 to December 2021. Socio-demographic details and information about risk factors were noted. A detailed corneal examination followed by corneal scraping was performed for microbiological evaluation. Results: In 1 year, 99 infective corneal ulcer patients were evaluated. Farmers (24.2%) were found to be maximally affected by corneal ulcers. The peak in cases was recorded from October to December (38.4%). Ocular trauma was the commonest risk factor (42.4%). The majority (80.8%) of patients were already on some topical antimicrobials. 22.2% of samples showed fungal filaments on KOH mount; 54.5% of these cases turned out to be culture-positive. 17.56% of KOH-negative samples turned out to be culture-positive (fungal). Overall, the culture positivity rate was 28.28% out of which fungal isolates were 89.28% and bacterial isolates were 10.72%. Fusarium species were identified as the most common organism contributing 42.85%, followed by Aspergillus fumigatus (14.28%). 10.72% of cases were culture positive for Pseudomonas aeuroginosa. Conclusion: Trauma with the organic matter was the predominant cause of fungal keratitis. In this study, fungal keratitis was found to be more common. Fusarium was the most common isolate.

Role of amniotic membrane transplantation in treating acute ocular manifestations in Steven-Johnson syndrome and its long-term impact.

Background: Steven-Johnson syndrome (SJS) is a serious disorder affecting the skin and mucous membrane, causing multiple flaccid bullae and purpuric rashes with sheet-like epithelial detachment including the ocular surface. The long-term outcomes following SJS are dismal and manifest as corneal vascularization, lid-wiper keratopathy, and severe dry eyes. The disease course can be modified if amniotic membrane graft is performed at the first week of disease, and the above-said complications can be avoided. This procedure thus not only decreases the morbidity but also improves the quality of life. Purpose: This video discusses the long-term sequelae of SJS which can be modified with timely intervention during the acute stage and thus significantly decreases morbidity. Synopsis: The video demonstrates the simple technique of amniotic membrane transplantation in the acute stage in SJS and its impact in long run. Highlights: There should be a low threshold for doing early amniotic membrane transplantation in patients with SJS with ocular surface involvement. Early intervention can change the disease course and decrease disease morbidity significantly. Video link: https://youtu.be/qgIiVcW56Oo.
