PURPOSE: To report nontubercular choroiditis, caused by Mycobacterium mageritense isolated using MALDI-TOF MS, following laparoscopic hysterectomy in an immunocompetent patient. CASE REPORT: A 42-year-old female presented with gradual, painless diminution of vision in the right eye for six weeks. She had undergone laparoscopic hysterectomy two months back. BCVA was 2/60 OD. Clinical presentation and imaging all pointed to a diagnosis of serpiginous-like choroiditis. Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) had led to isolation of Mycobacterium mageritense. Patient was treated with systemic antibiotics. At 3 months follow up, BCVA improved to 6/60; fundus showed healed choroiditis and chorioretinal thinning. CONCLUSION: Atypical mycobacterial infections associated with laparoscopic surgeries can rarely lead to debilitating systemic bacteremia resulting in profound visual impairment. The importance of timely diagnosis using specific and sophisticated methods such as MALDI-TOF MS as well as maintaining aseptic precautions perioperatively during major surgeries cannot be overemphasized.

Cataract is an eye disease of major human concern and its prevention is important to control the global incidences of blindness. The emergence of cataract in the eye lens by strong UV radiation and growing pollution could be effectively reduced by natural antioxidant biomolecules such as flavonoids, phenolic acids, carotenoids and vitamins. This goal can be achieved either by direct external use of antioxidant biomolecules in the form of topical application as an eye drops, food supplements or through nanobiotechnology based formulation without any side effects. In this manuscript, we have discussed the mechanisms of cataract formation and the preventive role of different classes of natural antioxidant biomolecules. Further, role of nanobiotechnology to enhance therapeutic potential of these natural antioxidant molecules by enhancing solubility, stability, bioavailability and sustained release has been briefly discussed.

A child with Goldenhar's syndrome, bilateral choroidal colobomas, and a morning glory anomaly of the optic disk in one eye is described. Bilateral posterior segment anomalies associated with Goldenhar's syndrome are rare. An association between the morning glory anomaly and Goldenhar's syndrome has not been previously reported.
