Postkeratoplasty astigmatism was evaluated during examinations 1, 3, and 6 months postoperatively and 2 months after completing suture removal.Results: Twenty-four eyes had single running sutures, 16 eyes had interrupted sutures, and in 14 eyes the suturing technique used was combined interrupted and running sutures. Mean age was 25.6 ± 5.9 years, 27.3 ± 6.8 years, and 26.5 ± 5.7 years (P = 0.422), and postoperative astigmatism 1 month after surgery was 3.79 ± 1.19 D, 5.56 ± 1.78 D, and 4.21 ± 1.55 D in the three groups, respectively (P = 0.012). However, 2 months after completing the suture removal, final postoperative astigmatism was 3.43 ± 1.44 D, 3.87 ± 1.38 D, and 3.71 ± 1.46 D (P = 0.846). Final astigmatism less than 4 D was seen in 18 cases (75%) in the single running group, nine cases (56.2%) in the interrupted running group, and nine cases (64.2%) in the combined interrupted and running group (P = 0.08).Conclusion: Postkeratoplasty astigmatism is comparable with three different suturing techniques used in patients with keratoconus after completing suture removal in DALK. Due to earlier suture removal in DALK, the type of suturing technique used is not considerably important.Keywords: astigmatism, deep anterior lamellar keratoplasty, suturing technique

Aim: The aim of the study is to describe the demographic and clinical features of Behcet disease (BD) in paediatric patients. Methods: The study included 62 patients who presented to the Department of Ophthalmology at Ankara Education and Research Hospital, Ankara, Turkey and diagnosed as having BD. These patients were placed into three age groups based on the age at the time of BD presentation: group 1, birth to 10 years old; group 2, 11-15 years old; group 3, 16-20 years old. Among these three age groups, the objective was to identify the ocular and extraocular clinical findings and complications of BD, and to uncover the role of gender, if exists, in the aetiology of the disease. Results: The findings indicated that gender played no significant role in the aetiology of BD. In group 1, a family history of BD was more prevalent, and the most common ocular finding was bilateral anterior uveitis. The most frequent form of ocular involvement in groups 2 and 3 was bilateral panuveitis with retinal vasculitis and retinitis. The majority of disease complications were glaucoma, maculopathy and cataract formation. Conclusion: Patient age appeared to define the type of ocular involvement in BD. While anterior uveitis was the most frequent ocular finding in BD patients younger than 10 years, panuveitis was the most frequent in patients older than 10 years. As a family history of BD was more frequent among patients younger than 10 years, family screening for BD is considered critical for early and accurate diagnosis of BD, as well as for the control of its complications.
