Ocular and Neuro-ophthalmic Manifestations Post COVID-19 Infection.

A 39-year-old male with a history of COVID-19 infection presented with ocular manifestations: dendritic ulcer in the left eye cornea followed by diplopia in the same eye. Extraocular motility was restricted in the levo-lateral gaze with maximum diplopia measuring 25∆ exotropia. Slit lamp biomicroscopy showed dendritic patterned lesion with diffused superficial punctate keratitis in the cornea. There are various reports associated with COVID-19 and the neuro-ophthalmic system. Although the clinicopathological aspect of COVID-19 and the neurological system is still to explicate. However, the patient showed gradual improvement with topical and systemic antiviral therapy and orthoptic exercise. This points to the need for detailed neurological and ophthalmic workup in symptomatic COVID-19 patients. Taking the risk of viral spread into serious consideration, a thorough evaluation is though mandatory. Keywords: COVID-19; dendritic ulcer; lateral rectus palsy; superficial punctate keratopathy.

Evaluation of dry eye symptoms in lecturers working in medical colleges of Nepal: An online cross-sectional study following SARS-CoV-2 outbreak.

INTRODUCTION: Dry eye is one of the frequently encountered ophthalmological disorders. Following the pandemic of Coronavirus disease 2019, use of masks and electronic devices has taken an upraise globally. These factors are one of the causes for dry eye disease. This study emphasises dry eye symptoms among lecturers working in medical colleges of Nepal. MATERIALS AND METHODS: This was a descriptive cross sectional study conducted among 217 lecturers working in various medical colleges in Nepal. Dry eye evaluation was done using the Ocular Surface Disease Index (OSDI) questionnaire. Analysis of data was using Microsoft Excel 2016 and IBM Statistical Package for Social Sciences (SPSS) version 26.0. RESULTS: One fourth (25.80%) of 217 participants experienced symptoms of dry eye disease. CONCLUSION: Increasing use of mask and laptop during this pandemic era has shown to cause mild dry eye symptoms in lecturers working in medical colleges of Nepal. Proper care and precaution needs to be practised in order to minimise dry eye symptoms and its consequences.

Comparative Study of Dry Eye Indices Following Cataract Surgery.

BACKGROUND: This study aims to assess dry eye indices following cataract surgery. MATERIALS AND METHODS: A single center descriptive and comparative study was performed. A total of 100 eyes of 100 cases fulfilling the inclusion criteria from 1st June 2017 to 30th May 2018 were enrolled. Out of 100 eyes, 50 eyes each went through manual small incision cataract surgery (MSICS) and phacoemulsification respectively. For objective analysis : schirmer 1 test(ST-I), tear breakup Time(TBUT) along with lissamine Green Surface Staining(LGSS) was performed on pre-operative day, 1st, 4th and 12th week respectively. Ocular Surface Disease Index (OSDI) was done for subjective analysis on pre-operative day and at 12th week. RESULTS: The mean age of the patient was 53.66 ± 7.839 years with 34 (68%) being female in a small incision cataract surgery group. In the phacoemulsification group, mean age was 54.72 ± 7.985 years and 32 (64%) were female. On analyzing the objective dry eye indices: ST-I,TBUT and LGSS at 12thweek was 18.80 ± 7.393 mm, 11.30 ± 5.456 seconds and 1.62 ± 1.193 in Small incision cataract surgery group and 27.10 ± 6.326 mm, 16.60 ± 4.699 seconds and 0.38 ± 0.602 in Phacoemulsification group respectively which was statistically significant. (p< 0.001). CONCLUSION: Regardless of the type of cataract surgery, dry eye disease is unavoidable affecting both tear quality and quantity postoperatively. In our study, phacoemulsification had lesser effect in dry eye indices than small incision cataract surgery.
