Background: Endophthalmitis is one of the most serious complications of ophthalmic surgery, which includes postoperative cataract extraction. Outbreak of acute postoperative endophthalmitis after cataract surgery has been reported in Thailand and other countries.

Objective: To describe an outbreak of acute postoperative endophthalmitis after cataract surgery that was referred to Chiang Mai University Hospital during March 2006.

Material and method: Observational case series were made from the records of inpatients and outpatients, who had been referred for treatment of acute postoperative endophthalmitis after cataract surgery at a district hospital in northern Thailand. The surgery was conducted on two consecutive days by volunteer ophthalmologists of a non-profit foundation from Bangkok.


Results: In this outbreak, the authors recorded 31 endophthalmitis cases, with 33 eyes (bilateral 2 cases). Of the 33 endophthalmitis eyes, 32 occurred following extracapsular cataract extraction with intraocular lens and one after the secondary intraocular lens implant. Microbiological investigations in the hospital were done with aqueous tapping, vitreous tapping, and vitreous from pars plana vitrectomy. Gram-positive cocci were detected from vitreous tapping in four eyes. Thirty-two cases were managed with intravitreous antibiotics, one with subconjunctival antibiotic only, and all eyes were treated with fortified topical antibiotics. Fifteen eyes underwent pars plana vitrectomy Assessment of visual acuity (VA) before and after treatment showed improvement in 75.8% (25/33), decrease of VA in 9.1% (3/33), while visual acuity remained stable in 15.2% (5/33).

Conclusion: In high-volume cataract surgery, an outbreak of endophthalmitis is always possible. Prompt and appropriate treatment can improve the visual outcome.


Vision therapy is well worth the response, time and effort. Our Son had a hard time focusing and writing neatly. After vision therapy Seth could complete a task in half the time if previously took. His abilities to focus improved greatly and so did his handwriting.

Also, he was better at listening. As a parent, we wanted learning to be fun for our Son, and vision therapy made this possible.

Vision Therapy is well worth the expense, time and effort. Our son had a hard time focusing handwriting neatly. After vision therapy Seth could complete a task in half the time it previously took his abilities to focus and improved greatly and so did his handwriting.

Vision Therapy has given or son the tools he needs to be able to scan and read the written word more effectively and efficiently.

He love working with John and these working sessions give him the motivation to gladly work on his homework assignments.

It amazed us to see the difference in the tracking of his eyes and along a line of it's from the beginning to the end of the treatment.

Dr. McBryar , Kristen and John  are all marvelous and we would recommend them to anyone I only wish that we would have found them sooner!

Prior to coming to the institute for vision development my son complained of daily headaches. Therapy has eliminated his headaches completely. I love knowing my son is able to learn pain-free for the rest of his life because of the work that has been done over just a few weeks in this office. He he absolutely loved coming that didn't even feel like going to a doctor or therapy. We are grateful for the relief he was able to find by coming here.

Thank you!

When we first came to the practice, my son did not have huge issues, but lots of small ones- trouble with reading, sports (hitting the baseball consistently), coordination, etc- that were not easily detectable,but when put together presented issues. The staff here were all very professional and loving towards him. While I was concerned in the reading, my son was concerned with the athletic side. Seeing improvement night off the bat gave him confidence that i have nor seen in him and made him want to not only Come to therapy, but also made him want to work hard. He has surpassed his grade level and above in reading and hit his first home run this year! Thank you!!!
