Uveitis is composed of a diverse group of disease entities, which in total has been estimated to cause approximately 10% of blindness. Uveitis is broadly classified into anterior, intermediate, posterior and panuveitis based on the anatomical involvement of the eye. Anterior uveitis is, however, the commonest form of uveitis with varying incidences reported in worldwide literature. Anterior uveitis can be very benign to present with but often can lead to severe morbidity if not treated appropriately. The present article will assist ophthalmologists in accurately diagnosing anterior uveitis, improving the quality of care rendered to patients with anterior uveitis, minimizing the adverse effects of anterior uveitis, developing a decision-making strategy for management of patients at risk of permanent visual loss from anterior uveitis, informing and educating patients and other healthcare practitioners about the visual complications, risk factors, and treatment options associated with anterior uveitis.
Cataract surgery in uveitic eyes is often challenging and can result in intraoperative and postoperative complications. Most uveitic patients enjoy good vision despite potentially sight-threatening complications, including cataract development. In those patients who develop cataracts, successful surgery stems from educated patient selection, careful surgical technique, and aggressive preoperative and postoperative control of inflammation. With improved understanding of the disease processes, pre- and perioperative control of inflammation, modern surgical techniques, availability of biocompatible intraocular lens material and design, surgical experience in performing complicated cataract surgeries, and efficient management of postoperative complications have led to much better outcome. Preoperative factors include proper patient selection and counseling and preoperative control of inflammation. Meticulous and careful cataract surgery in uveitic cataract is essential in optimizing the postoperative outcome. Management of postoperative complications, especially inflammation and glaucoma, earlier rather than later, has also contributed to improved outcomes. This manuscript is review of the existing literature and highlights the management pearls in tackling complicated cataract based on medline search of literature and experience of the authors.
ABSTRACT.Purpose: To report the results of Descemet's stripping endothelial keratoplasty (DSEK) for failed therapeutic penetrating keratoplasty (PK). Methods: Twenty-seven eyes of 27 patients undergoing DSEK for failed therapeutic PK were analysed. Results: The mean age of the patients was 36 ± 13.9 years (range: 14-70 years).The median size of the therapeutic graft was 10 mm (inter-quartile range; IQR 9.5-11 mm). Descemet's membrane stripping was performed in all eyes. Graft clarity was achieved in 20 ⁄ 27 eyes. Six eyes had primary graft failure, and one had interface keratitis in the early postoperative period. In all eyes with primary graft failure, there was progressive stromal vascularization, which led to haziness in the graft. Late postoperative complications were rejection in four eyes, infection in two eyes, secondary graft failure in one eye and vortex keratopathy in one eye. Graft size was found to be a significant risk factor for graft rejection in this series. At the last follow-up visit, the best-corrected visual acuity was ‡20 ⁄ 40 in 5 ⁄ 27 eyes (18.5%), 20 ⁄ 60-20 ⁄ 40 in 12 ⁄ 27 eyes (44.4%), 20 ⁄ 100-20 ⁄ 60 in 3 ⁄ 27 eyes (1.5%) and £20 ⁄ 200 in 7 ⁄ 27 eyes (25.9%). Conclusions: Considering the limited success of repeat PK in failed large therapeutic keratoplasty, DSEK is a viable option for visual rehabilitation in these eyes, however; visual acuity may be limited due to sub-epithelial ⁄ stromal or interface scarring.
Corneal scarring with cataract is the most common reason for triple procedure in this part of the world. This is a safe surgical procedure with good graft clarity and reasonable visual recovery.
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.
