RESUMO
Scleral necrosis is a rare occurrence after many ocular procedures. In the absence of infection or use of surgical adjuncts such as antimetabolites or radiation, the necrosis is presumed to be directly related to surgical trauma and is hence termed surgically induced necrotizing scleritis (SINS). A high index of suspicion is required for an early diagnosis of SINS and its differentiation from infective scleritis is important as the treatment modalities of these two related conditions are different. We report a case of SINS at sclerotomy site following 23-gauge transconjunctival retinal detachment surgery that was initially suspected to be a scleral abscess. Prompt recognition and institution of topical and systemic steroid therapy helped in limiting the extent of scleral damage.
RESUMO
PURPOSE: To study the anatomic and functional outcome of air descemetopexy in postcataract surgery Descemet's membrane detachment (DMD). DESIGN: Retrospective study. METHODS: Setting: Institutional. STUDY POPULATION: Records of 112 patients who underwent air descemetopexy for postcataract surgery sight-threatening DMD at Aravind Eye Hospital, Pondicherry, between January 2013 and December 2015 were studied. MAIN OUTCOME MEASURES: Anatomical outcome refers to reattachment of the Descemet's membrane (DM). Functional outcome was given by the best-corrected visual acuity. RESULTS: The mean age was 66.47±8.46 (SD) years, the male to female ratio was 45:67. The incidence of DMD was more in extracapsular cataract extraction (0.26%) and manual small incision cataract surgery (0.11%) than phacoemulsification (0.04%) (p=0.005 and p<0.0001). DMD was more common among surgical trainees (0.17%) than consultants (0.07%) (p≤0.0001). After primary air descemetopexy, 78 (71%) out of the 110 patients had DM reattachment. The complications noted after descemetopexy include persistent DMD (21.8%), corneal decompensation (7.3%), appositional angle closure (18%), pupillary block with air (2.7%) and uveitis (2.7%). Age, sex and timing of intervention did not influence the reattachment rate. Fifteen patients underwent repeat air descemetopexy for persistent DMD among whom nine (60%) had successful reattachment. Almost 75% of patients had vision better than 6/18 1 month after anatomically successful descemetopexy. CONCLUSION: Air descemetopexy is a safe and efficient modality of treatment of DMD and should be tried even in patients with severe DMD before planning a major surgery like endothelial keratoplasty.
