Postoperative endophthalmitis is a very devastating complication and every step should be taken to reduce its occurrence. Unattended air conditioning filter systems are often the culprits and regular maintenance of the filters is of paramount importance. Shedders of pathogenic organisms amongst the theater personnel should be identified by regular screening and should be promptly treated. In addition to the use of Povidone iodine 5% solution in the conjunctival sac few minutes prior to surgery, proper construction of wound, injectable intraocular lenses, use of prophylactic intracameral antibiotics or prophylactic subconjunctival antibiotic injection at the conclusion of cataract surgery, placing a patch after the surgery for at least 4 h and initiating topical antibiotics from the same day of surgery helps to lower the frequency of postoperative endophthalmitis. Intraoperative posterior capsule rupture and anterior vitrectomy are risk factors for acute endophthalmitis, and utmost care to prevent posterior capsular rent should be taken while performing cataract surgery. Also, in case of such complication, these patients should be closely monitored for early signs of endophthalmitis in the postoperative period. In the unfortunate event of endophthalmitis the diagnosis should be prompt and treatment must be initiated as early as possible.

Modern day dermatologists conduct different esthetic and surgical procedures, with risk of infective complications. Hence, infection control practices need to be established in dermatological practice to minimize the risk of exogenous infections. These practices include hand washing, cleaning, sterilization, disinfection, operation theater sterilization and specifications. Proper hand washing after examination of each patient and prior to any surgery with a formulation containing alcohol alone or as a combination with other agents reduces the chances of transferring infections to and from patients. Sterilization and disinfection constitute the most important aspect of infection control. Disinfectants and disinfecting procedures vary according to the environment and equipment. Proper knowledge of different processes/agents for sterilization and disinfection is essential. Disinfectants for use in hospitals should always be freshly prepared and should be of adequate strength. Sterilization is carried out most commonly using steam sterilizers or ethylene dioxide sterilizers. The waste generated during practice is a potential source of nosocomial infections and should be treated as per the proper protocol and guidelines. Trained staff to carry out these practices is essential.

Five patients developed endophthalmitis after cataract surgery. on evaluation of operation-theatre complex, fungal spores were demonstrable from environment and surfaces. Air conditioner's filters were grossly contaminated. Aspergillus and Mucor spp. were isolated. Phenotypically similar fungi were isolated from three of the patients (Aspergillus spp. from two and Mucor spp. from one). As a follow up study, filters of the air conditioning devices in twenty five operating rooms of hospitals nearby were evaluated periodically. The results of this surveillance study were used to educate the hospitals about need for routine cleaning and disinfection of gadgets, like air conditioners, for minimizing the chances of proliferation and dispersal of potentially pathogenic fungi.
