Dear editor,
I must thank Sarkar et al for their insightful study into the COVID effect on ocular symptoms. Although the pandemic has been raging on for close to 2 years now, there is still limited information on the ocular manifestation in COVID patients.
However, I would like to point out the lack of information on the demographic of their study group. Whilst Sarkar et al has provided information on the age group of participants, giving the readers the idea that the ocular manifestation is more prominent in higher age group, It failed to address the fact that gender plays an important factor too. As demonstrated in studies like Borrelli et al [1] and Nøland et al [2], symptoms such as dry eyes etc are much more common in the female population. Hence, the study would have been more convincing if the information on the gender of the participants were made available.
In addition to the point above, I would like to highlight that this study did not address the variation of severity of COVID infection in group 1. As concluded in studies like Johansson et al [3] and Son et al [4], there is substantial variation in symptoms among patients with similar viral load. This would bring to question as to whether the manifestation of ocular symptoms is directly influenced by the level of viral load itself or the severity of systemic COVID symptoms from.
Lastly, Sarkar et al should address if patients with severe COVID infection were excluded from the st...
