Abstract
Abstract: :
Purpose: To know the frequency, etiology and final visual outcomes associated with each of the different types of endophthalmitis seen at our institution during the last ten years. Methods: Records of patients with the diagnosis of endophthalmitis were retrospectively reviewed from January 1990 to September 2001. A database was designed for each type of endophthalmitis to register demographic variables, medical and ophthalmic history, clinical course, causative microorganism or microorganisms, type of treatment and final visual outcomes. Results: A total of 97 cases of endophthalmitis were included: 41% post-traumatic, 53% post surgical (31% cataract surgery, 12% glaucoma surgery and 10% other type of intraocular surgery) and 6% endogenous. The most common causative agents were Staphylococus epidermidis for post-surgical and endogenous endophthalmitis and Staphylococus epidermidis and Bacillus cereus for post-traumatic endophthalmitis. Visual improvement was seen in 31% of post-traumatic 24% cataract surgery 18% glaucoma and 33% after endogenous endophthalmitis Conclusion: The most common cause of endophthalmitis at our hospital was secondary to surgery followed by trauma. The microorganism most frecuently cultured was Staphylococus epidermidis. Only a few patients showed improvement in final visual acuity.
