During retrospective and prospective studies, we attempted to determine the clinical characteristics, treatment, and visual outcome of patients with pars planitis and to evaluate the association between pars planitis and multiple sclerosis (MS). The retrospective study included 44 patients with pars planitis, who had been examined between October 1986 and January 1999. We analyzed age, sex, visual acuity (VA), median follow-up time, and medical and surgical treatments. The prospective study, which included 21 consecutive patients with pars planitis, was performed to determine the presence of MS. In the retrospective study, the mean patient age was 22.4 years (SD +/- 11.5) and the median follow-up was 34.9 months (SD +/- 27.2). Complications included macular edema (47.7%), vitreous opacities (38.6%), papillitis (38.6%), vasculitis (36.4%), and cataract (20.5%). Forty patients (90.9%) had a final bilateral VA better than 20/40. In the prospective study, magnetic resonance imaging (MRI) was performed. Demyelinating lesions were found in 10 (47.6%) of the 21 patients and relapsing-remitting clinically definite MS was diagnosed in seven (33.3%). With the exception of age, no significantly statistical differences were observed when the visual prognosis and the clinical and epidemiologic characteristics were compared between the two groups of patients with and without associated MS; a diagnosis of MS was more frequently made in patients over 25 years of age. With appropriate treatment, patients with pars planitis have a good visual prognosis. Because the presence of demyelinating lesions seems to be high among patients with pars planitis, MRI should be considered, especially in patients over 25 years of age.
Posterior capsule opacification, glaucoma, and vitreous opacity were the major obstacles to visual rehabilitation after cataract surgery in patients with this type of uveitis.
ABSTRACT.Purpose: To evaluate the results of a protocol described for mitomycin C (MMC) use in trabeculectomy or combined surgery (phacoemulsification and trabeculectomy). Methods: A total of 143 eyes (60 trabeculectomies and 83 combined surgeries) of 124 patients were divided into four groups: group 1 (without MMC); group 2 (with 0.1 mg/ml MMC); group 3 (with 0.2 mg/ml MMC), and group 4 (with 0.4 mg/ml MMC). Two-minute MMC was used in every case in groups 2, 3 and 4. The results were analysed after 1 year of follow-up. Intraocular pressure (IOP) and complications were evaluated. Successful IOP control was defined when IOP was <21 mmHg and <16 mmHg if advanced glaucoma was present, always without additional medical treatment. Results: Mean preoperative IOP decreased from 24.60 mmHg (SD 1.40 mmHg) to 13.47 mmHg (SD 0.37 mmHg) (p < 0.00001), 12 months postoperatively. Control in IOP was achieved in 79.02% of eyes. No significant differences were found in final mean IOP values (p > 0.196) or in postoperative complications (p > 0.120) in groups 2, 3 and 4. Conclusion: With the protocol described, a selection of concentration of MMC has been made in different clinical forms of glaucoma. No significant differences in IOP control and postoperative complications were noticed among the groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
