ABSTRACT: PURPOSE: To investigate a possible effect of intraocular inflammation on corneal endothelium by describing corneal endothelial cell density (ECD) and morphologic variables in eyes with anterior uveitis, and to investigate factors that may influence these findings. DESIGN: Cross-sectional, observational study. Observers were not masked. PARTICIPANTS: Volunteers with histories of unilateral or bilateral anterior segment inflammation (anterior, intermediate, or panuveitis); included were 52 patients (84 eyes with uveitis). METHODS: Endothelial cell density and morphologic variables of both eyes of all study participants were determined by specular microscopy; central corneal thickness was determined by ultrasound pachymetry. MAIN OUTCOME MEASURES: Central corneal ECD, coefficient of variability, percentage hexagonality, and central corneal thickness. RESULTS: Central ECD was lower among eyes that had undergone cataract or glaucoma surgery or both (n = 28; P = 0.0004). After exclusion of eyes with surgery, variables for eyes with uveitis (n = 56) were compared with 2 historical populations of normal, age-matched controls and with contralateral eyes in individuals with unilateral uveitis. Central ECD was lower in eyes with uveitis than in control eyes for all age groups (P ≤ 0.01 for four of six 10-year age intervals compared with the primary control group). Among patients with unilateral uveitis who had not undergone surgery in either eye (n = 12), central ECD was lower in eyes with uveitis (2324 cells/mm(2) [range, 1543-3289 cells/mm(2)]) than in contralateral eyes (2812.5 cells/mm(2) [range, 1887-3546 cells/mm(2)]; P = 0.0005), and percentage hexagonality was lower in eyes with uveitis (54% [range, 33%-66%]) than in contralateral eyes (58.5% [range, 52%-82%]; P = 0.004). There was no significant difference in central corneal thickness between eyes with and without uveitis (P = 0.27). No eyes had clinically apparent central corneal edema. Relationships remained unchanged after exclusion of eyes with herpetic anterior uveitis. Host and disease-related characteristics were evaluated as risk factors for variations in outcome measures. Central ECD was correlated to the duration of active uveitis (r = -0.41; P < 0.0001), maximum intraocular pressure during the course of disease (r = -0.40; P = 0.0002), and maximum laser flare photometry value (r = -0.26; P = 0.020). CONCLUSIONS: Observed relationships suggest that anterior segment inflammation adversely affects the corneal endothelium. Longitudinal studies are warranted to determine whether long-standing anterior uveitis increases risk of endothelial dysfunction, especially in the setting of intraocular surgery.

2 Article Cataract surgery under systemic infliximab therapy in patients with refractory uveitis associated with Behcet disease. 2014

Alfawaz, Abdullah / Alrashidi, Sultan / Kalantan, Hatem / Al-Mezaine, Hani / Abu, Ahmed M. ·Dr. Abdullah Alfawaz, Department of Ophthalmology, College of Medicine, King Abdulaziz University Hospital, PO Box 245, Riyadh 11411, Saudi Arabia, T: +966114775723, F: +966114775724, abfz22@hotmail.com. ·Ann Saudi Med · Pubmed #25811206.

ABSTRACT: BACKGROUND AND OBJECTIVES: This study is to evaluate the outcome of cataract surgery in patients with refractory uveitis associated with Behçet disease (BD) treated with infliximab. DESIGN AND SETTINGS: A retrospective study in a university-based tertiary referral center in the period between July 2003 and November 2011. METHODS: This is a retrospective study of patients with refractory uveitis associated with BD who underwent phacoemulsification cataract surgery under systemic infliximab therapy between July 2003 and November 2011 at King Abdulaziz University Hospital, Riyadh, Saudi Arabia. RESULTS: Six patients (9 eyes), 5 of which were male and 1 female, were identified in this study. The mean (SD) age and follow-up period were 26.2 (6.6) years (range, 16-36 years) and 51.6 (28.8) months (range, 12.84 months), respectively. All the patients underwent phacoemulsification with intraocular lens implantation. Postoperatively, visual acuity improved in all eyes and was 20/40 or better in 7 eyes (77.8%). In the immediate postoperative period, anterior chamber inflammation ranged from 2+ to 3+ cells. None of the patients developed inflammation relapse postoperatively. The most common postoperative complication was posterior capsular opacification in 5 eyes (55%), 4 of which were managed with neodymium:yttrium-aluminum garnet laser capsulotomy. Three eyes had glaucoma, 2 of which underwent successful glaucoma surgery and one was managed with topical antiglaucoma medications. CONCLUSION: In patients with refractory uveitis associated with BD who are treated with infliximab, cataract surgery is safe and has a good prognosis.

3 Article Efficacy of punctal occlusion in management of dry eyes after laser in situ keratomileusis for myopia. 2014

Alfawaz, Abdullah M / Algehedan, Saeed / Jastaneiah, Sabah S / Al-Mansouri, Samir / Mousa, Ahmed / Al-Assiri, Abdullah. ·Department of Ophthalmology, College of Medicine, King Saud University , Riyadh , Kingdom of Saudi Arabia . ·Curr Eye Res · Pubmed #24147767.

ABSTRACT: PURPOSE: To evaluate the effect of punctal plug use in preventing dry eye after laser in situ keratomileusis (LASIK). MATERIALS AND METHODS: A randomized clinical trial at a tertiary eye care center, Riyadh, Saudi Arabia. Participants underwent LASIK for myopia in both eyes and a lower punctal occlusion in one eye only while the other eye served as control. Both eyes received the same postoperative medications except for lubricant duration (subject eye: four times per day for one week; control eye: four times per day for 6 months). Participants were evaluated at 1 week, 2, and 6 months after surgery for signs and symptoms of dry eye. The main outcome measures were visual acuity; ocular surface parameters; and Ocular Surface Disease Index questionnaire. RESULTS: Seventy-eight eyes of 39 patients were included in this study. The Ocular Surface Disease Index scores of eyes with punctal plugs were better at all follow-up visits, and the differences between both eyes were statistically significant (1 week, p < 0.0001; 2 months, p < 0.0001; 6 months, p = 0.008). At the final follow-up visit, the percentage of normal eyes was higher in eyes with punctal plugs for all ocular surface parameters (Schirmer 1 test, 94.9%; tear breakup time, 77.8%; punctate epithelial keratitis score, 71.8%) compared to eyes without occlusion (Schirmer 1 test, 92.3%; tear breakup time, 58.3%; punctate epithelial keratitis score, 53.8%); however, such differences were not statistically significant. CONCLUSION: Punctal plug insertion after LASIK surgeries may minimize the need for frequent lubricant application and hence improve patient satisfaction.
