In developing countries like India, Linezolid is widely used for the treatment of Multi drug resistant tuberculosis (MDR-TB) and extensively drug resistant tuberculosis (XDR-TB). Long-term administration of Linezolid is reported to cause toxic optic neuropathy causing bilateral, progressive visual loss in patients. We report case details of three patients on anti-tubercular therapy presented to us with sudden, progressive, painless blurring of vision of both eyes the cause of which was confirmed to be toxic optic neuropathy due to linezolid.

Purpose: Aim of this study was to compare the efficacy of sodium hyaluronate (SH) and carboxymethyl cellulose (CMC) eye drops in treating mild to moderate dry eye disease in terms of relief of symptoms, mean change in tear film breakup time, Schirmer's test, and impression cytology of conjunctiva from baseline.

Methods: An observational study was carried out during a 2-year period in our tertiary referral hospital. The study consisted of 60 patients randomly allotted to two groups to receive SH and CMC eye drops for an 8-week period.

Purpose: Dry eye disease (DED) is because of a decrease in the tear film's volume or a change in the composition of tears. Evaporative dry eye is the most common type, which is due to meibomian gland dysfunction (MGD). In this study, the morphology of meibomian glands was evaluated in all kinds of dry eyes to look for any loss of meibomian glands, assess the function of remaining glands, and investigate the relationship between anatomy, function, and severity of DED.

A 37-year-old woman presented with progressive large-angle esotropia (>140(Δ)) since childhood. Her best-corrected visual acuity was 20/80 in right eye and unrecordable in the left eye because of severe esotropia and limitation of abduction. Computed tomography of the orbits showed presence of nasal displacement of the superior rectus muscle and inferior displacement of the lateral rectus muscle in the left eye, which was confirmed intraoperatively.

Importance: Tuberculosis is an endemic infectious disease in developing countries. Patients receiving treatment for systemic tuberculosis may develop paradoxical growth of tuberculomas in the brain, which can lead to vision loss.

Observations: We describe 3 patients who had paradoxical development of tuberculomas in the anterior optic pathway during treatment for tuberculosis and presented with acute vision loss.
