**2. The etiology of endophthalmitis**

The spectrum of the microorganisms causing endophthalmitis may differ in different parts of the World. According to the Western literature, over 75% of culture positive cases of en‐ dophthalmitis are due to Gram-positive bacteria that includes, Staphylococcus species, Streptococcus species, Enterococcus species, and other Gram-positive species. [2, 3] Gramnegative species may account for up to 6% of endophthalmitis cases. Studies from other countries such as India reveal that Gram-positive bacteria may account for 53% of post-oper‐ ative cases of endophthalmitis and up to 26% may be due to Gram-negative bacteria, while rest 17% may be due to fungal infection.
