ABSTRACT
An 80-year-old systemically stable female presented with sudden blurring of vision post the first dose of Covishield™, a non-replicating viral vector vaccine. On examination, she was found to have bilateral serous choroidal effusions. A thorough systemic and ocular workup was performed to rule out other causes of choroidal effusion. The effusions resolved with tapering doses of oral and systemic steroids. To the best of our knowledge, at the time of submission, this is the first case of choroidal effusion being reported after the coronavirus disease 2019 (COVID-19) vaccine.
ABSTRACT
Purpose: To compare the intermediate-term refractive outcomes of a single-step and a two-step approach for silicone oil removal (SOR) and cataract surgery. Methods: Case records of patients who had SOR and phacoemulsification (PE) from 2011 to 2013 at a tertiary center in South India were retrospectively analyzed. A total of 135 eyes that underwent ultrasound biometry (UB) were studied. Eighty-seven eyes had SOR and PE at a single surgery (Group A), where as UB was done in a silicone oil (SO) filled eye. Forty-eight eyes had SOR followed by PE later (Group B), where UB was done in a fluid-filled eye. The refractive error (RE) and best-corrected visual acuity (BCVA) at postoperative day 45 (D45) and postoperative month 3 (M3) were compared. Results: Baseline axial length, intraocular lens (IOL) power, and RE in both groups were comparable. A myopic shift (4.18 ± 5.47 diopters [D]) was noted in 92% eyes at M3. Forty-nine percent eyes had a RE of ?±1.5D at M3. RE at D45 and at M3 was significantly lesser in Group B (?1.73 ± 2.04 vs. ?0.64 ± 1.75; P, 0.002). BCVA was significantly lesser in Group A at baseline, at D45, and at M3 (P < 0.01 for all). There was no difference in other baseline characteristics of eyes that had RE ?±1.5D and those that had RE >±1.5D at M3. Conclusion: SO-filled eyes had a myopic shift in refraction after SOR and PE. When UB is used for IOL power calculation, better refractive outcomes are obtained when SOR and PE are performed in a two-step approach.
