Abstract/Introduction

Purpose: To analyze the pattern of childhood uveitis in a referral center in Tunisia, North Africa.

Methods: The study included 64 patients with uveitis examined at the Department of Ophthalmology of Monastir (Tunisia) from January 1994 to July 2005. All patients had a comprehensive ocular and systemic history, including an extensive review of medical systems. Complete ophthalmic examination was performed in all cases, including best-corrected Snellen visual acuity, slit-lamp examination, applanation tonometry, and dilated fundus examination with 3-mirror lens. Standard diagnostic criteria were employed for all syndromes or entities of uveitis.

Conclusion/Results

Results: The mean age at onset of uveitis was 12.4 years. The male-to-female ratio was 0.68. The process was unilateral in 51.6% of patients. Mean follow-up was 43.2 months. Anterior and intermediate uveitis each represented 31.25% of cases, posterior uveitis 20.3%, and panuveitis 17.2%. Noninfectious uveitis (75%) was the most frequent type of inflammation. Idiopathic uveitis was found in 50% of patients. Infectious uveitis was responsible for 25% of the cases, with toxoplasmosis (14.1%) being the most frequent cause. Twenty percent of the patients had systemic associations; juvenile idiopathic arthritis was found in 6.25%. Ocular complications occurred in 74.7% of affected eyes, of which the most common were posterior synechiae (28.4%), cataract (17.9%), cystoid macular edema (19%), and optic disc edema (32.6%). Fifty-seven affected eyes (60%) had a final visual acuity more than 20/40 and nine (9.5%) had a final visual acuity less than 20/200.

Conclusions: In a hospital population in Tunisia, a specific cause of uveitis in children was found in half the patients. Idiopathic intermediate uveitis was the leading cause of uveitis in our study, followed by idiopathic anterior uveitis and toxoplasmosis. Uveitis associated with juvenile idiopathic arthritis was rare. Visual prognosis appeared to be good.

Testimonials

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 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!!!
