ABSTRACT
Purpose: Prolonged postoperative topical corticosteroids are commonly given after pediatric cataract surgery to control inflammation. This study was undertaken to compare the efficacy, safety, and compliance of postoperative topical steroids and adjunctive intracameral (I/C) triamcinolone acetonide (tricort) and posterior subtenon (PST) triamcinolone in modulating postoperative inflammation after surgery. Methods: Forty?eight eyes of children with pediatric cataract between the ages of 5 and 10 years were randomized into three equal groups (T, I, S) before surgery. Group T received postoperative topical 1% prednisolone tapered over 4 weeks; Group I received adjunctive intraoperative I/C 1.2 mg/0.03 ml tricort and topical 1% prednisolone for 2 weeks postoperatively, and Group S received a single 0.5 ml (40 mg/ ml) PST tricort without topical steroids. Signs of inflammation, intraocular pressure (IOP), and central corneal thickness were assessed at day 1, week 1, week 3, week 6, and week 12 postoperatively with optical coherence tomography (OCT) macula to rule out cystoid macular edema at the sixth and 12th weeks postoperatively. Results: Posterior synechiae were present in two eyes out of 16 in groups T and I, which resolved. Severe anterior chamber cells were present in four eyes out of 16 in group T, in two eyes in group I, and in one eye in group S, which resolved. All groups had comparable pre? and postoperative IOP. Conclusion: In pediatric cataracts, outcomes were better with PST tricort and the adjunctive I/C tricort compared to postoperative topical prednisolone, for modulating postoperative inflammation
ABSTRACT
Coronavirus disease 2019 (COVID-19) vaccinations have been associated with a higher risk of thromboembolic events. There have been no reports of central retinal artery occlusion (CRAO) after vaccination with the indigenously developed Covaxin, and worldwide, there has been only one such isolated case after administration of the AstraZeneca vaccine. We report a case of a 44-year-old healthy man who presented with sudden painless vision loss in his left eye 10 days after receiving Covaxin. His best-corrected visual acuity was minimal perception of light, with a relative afferent pupillary defect. Fundus examination revealed arterial attenuation and macular cherry red spot, suggesting an acute CRAO. Optical coherence tomography showed macular swelling and disorganization of the inner layers due to ischemic sequelae. Blood work was normal and cardiovascular examination was unremarkable. The patient was kept on follow-up. To our knowledge, this is the first case of an isolated CRAO after Covaxin administration, but further studies are needed to evaluate this potential association.
ABSTRACT
We report the case of a 22-year-old male, presenting with right enophthalmos and intermittent exophthalmos observed after valsalva maneuver. Orbital imaging revealed a retrobulbar vascular lesion with multiple phleboliths suggestive of orbital varices. On magnetic resonance angiography, no obvious feeder vessel could be delineated. We decided to manage the patient conservatively, in the absence of complications such as proptosis with corneal exposure, optic nerve compression, orbital hemorrhage. Orbital varix is a low flow vascular anomaly which generally presents with an intermittent exophthalmos. Development of enophthalmos associated with orbital varices as in our case, is very rare.
