RESUMO
Thromboembolic phenomenon related to Coronavirus disease 2019 (COVID-19) has been well documented in literature; however, reported ocular manifestations of COVID-19 are limited to vision sparing ocular conditions like conjunctivitis. We report a case of a 17-year-old female who presented to us with central retinal vein occlusion with proven recent past COVID-19 infection as presumed etiology which was not known to her at the time of presentation.

PURPOSE: Hypopyon in the eye is an alarming sign. A case of tuberculous uveitis which presented with pigmented hypopyon has been described. The aim of this paper is to report pigmented hypopyon, a rare presentation of tuberculous uveitis in a diabetic patient. OBSERVATIONS: A 42-year-old patient with diabetes with a known history of miliary tuberculosis, on anti-tubercular therapy since two months presented with complaints of pain and redness followed by diminution of vision in the right eye since one month. Visual acuity was counting fingers close to face in right eye. Anterior chamber (AC) showed grade 4 cells and flare with a pigmented hypopyon measuring two mm. Fundus details were not made out. B scan revealed increased choroidal thickness with moderate vitritis. Routine blood counts revealed leucopenia and anemia suggestive of an immunosuppressed state. AC tap analysis was not helpful in diagnosis initially. Patient was lost to follow up and presented one month later with three - fourth of AC having hypopyon. AC wash was done and the AC sample evaluation revealed acid fast bacilli. Polymerase chain reaction results confirmed it to be Mycobacterium tuberculosis. CONCLUSIONS AND IMPORTANCE: Tuberculous anterior uveitis thus presenting as pigmented hypopyon is very rare and can cause diagnostic difficulties. High index of suspicion in tuberculosis endemic areas is a must for a prompt diagnosis. A possible association between immunosuppression and pigmented hypopyon may exist and needs to be studied further.
RESUMO
AIMS: To create a normative data for lea grating (LG) in the Indian population and to compare LG with Cardiff Acuity Card (CAC). SETTINGS AND DESIGN: Normative Data was acquired from normal children between 6 months-3 years coming to the 'Immunisation Clinic' and 'Well-Baby Clinic' at a Civil Hospital. To compare LG with CAC, normal and amblyopic children between 6 months-3 years were evaluated, MATERIALS AND METHODS: Monocular and binocular visual acuity (VA) was measured using LG and then CAC. VA and time taken to perform the test were compared. STATISTICAL ANALYSIS USED: Pearson's Correlation Coefficient to compare VA and Student paired t-test (significance P<0.005) to compare time. RESULTS: Two standard deviations of VA of 100 normal children overlapped with that published by Lea. Of the 30 amblyopic children aged 18.32 ± 10.5 months (2-36), 18 were females. VA was 0.95 ± 0.3 logMAR (0.7-1.2) and 1.0 ± 0.6 logMAR (0.5-2.1) binocularly and 1.32 ± 0.08 logMAR (0.2-0.6) and 1.15 ± 0.15 logMAR (0.88-1.48) monocularly on CAC and LG respectively. Pearson's correlation coefficient was 0.98 and 0.63 for binocular and monocular assessment respectively. Time taken to perform LG monocularly and binocularly was significantly less (P<0.001) than CAC. CONCLUSION: Normative data acquired in Indian pre-verbal children is similar to that published by Lea. Though VA by CAC is better than LG, the two tests are comparable.
