Since December 2019, coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, has become a global pandemic. There has been a resurgence in complications involving various organs in patients recovered from COVID-19, and endophthalmitis is one of them. Endophthalmitis—an inflammation of intraocular tissues leading to loss of vision or even loss of eye—has been a rare occurrence in the past, but has been on the rise in the post-COVID-19 times. Here we report seven such cases.
Introduction: Cataract is most common cause of curable blindness worldwide and cataract surgery is most common procedure performed in ophthalmology. Posterior capsular opacification (PCO) is most common complication after cataract surgery which is usually treated with Neodymium-doped: Yttrium Garnet (Nd:YAG) laser posterior capsulotomy or occasionally with a surgical capsulotomy. The incidence and severity of PCO correlates to the type of surgical technique, IOL optic edge designs and IOL materials.
Material and Methods: 70 eyes of 64 patients operated for age related cataract were studied in this prospective interventional study. Phacoemulsification was done in 35 eyes and SICS in 35 eyes with hydrophobic single piece biconvex foldable intraocular lens. Patients were followed up at 1, 3, 6, 9 and 12 months for the development of PCO. Clinically significant PCO (loss of 2 or more lines of Snellen’s visual acuity chart) was treated with Nd:YAG laser capsulotomy.
Results: The overall incidence of PCO was 22.85%. Amongst the patients who developed PCO, SICS and phacoemulsification was performed in 62.5% and 37.5% patients respectively. Result was statistically significant with p value <0.05 using z test. On first postoperative day, patients operated with phacoemulsification had better visual acuity than SICS.
Conclusion: Phacoemulsification can provide early and better visual outcome than SICS and has lower incidence of PCO formation which may be due to difference in irrigation and aspiration and less disruption of blood aqueous barrier than SICS. PCO can be reduced by atraumatic surgery and thorough cortical clean up and capsular polishing.
Introduction: End stage renal disease (ESRD) patients undergoing hemodialysis (HD) have higher incidence of diabetic retinopathy (DR) and diabetic macular edema. Optical coherence tomography (OCT) which both diagnoses and quantifies degree of macular edema is gold standard for evaluating macular thickness.
Materials and methods: We studied 30 patients, with DR who were treated with hemodialysis for ESRD. All patients underwent OCT examination 30 minutes before and after a hemodialysis session. Blood pressure (BP), weight, serum osmolality, glycemic hemoglobin and albumin levels were measured before and after hemodialysis. Student’s t-test and linear regression analysis test were used to analyze data. SPSS version 21.0 system was used for all statistical analyses and p value <0.05 was accepted as statistically significant.
Results: In our study, BCVA failed to change significantly after the HD. Central and average macular thickness decreased by 3.49% and 1.61% respectively, both were statistically significant. Changes in maximum, central and average macular thickness, as well as in total macular volume were found to be significantly affected by changes in serum osmolality (p=0.04, 0.002, 0.02 and 0.03, respectively).We found no significant changes in maximum/average macular thickness with changes in total body weight or in mean arterial pressure after HD.
Conclusion: Hemodialysis significantly decreases maximum macular thickness assessed by OCT in chronic renal failure diabetic patients with macular edema with no change in BCVA. Osmolality changes after hemodialysis were significantly associated with macular thickness.
Many junior doctors feel that there are never enough hours in the day to do all their jobs. They end up feeling obliged to stay late to finish off routine tasks, reluctant to hand them over to the doctor on the late shift.
It is often said that: ‘One is a born leader and leaders cannot be made’, but to what extent is this statement true? What did Mahatma Gandhi and Adolf Hitler have in common that made them effective leaders, despite being very different individuals?
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.
