RESUMO
Background: Anti-vascular endothelial growth factor intravitreal injections (IVIs) have proved to be a boon for patients suffering from several retinal pathologies. They are one of the most commonly performed procedures in ophthalmology. A perioperative rise in blood pressure (BP) has been noted during cataract surgery. Objectives: To evaluate the perioperative BP changes during IVI, and the associated risk factors. Design: Cross-sectional observational study. Methods: The patients undergoing IVI from May 2019 to August 2019 were evaluated. All the patients underwent BP measurement before, during, and 1 h after the IVI. The correlation between the demographics and, the systemic comorbidities of the patients, and the ocular condition for which IVI was given was evaluated. Results: The study included 302 patients (mean age of 59.9 ± 10.7 years). The mean increase in systolic BP (SBP) and diastolic BP (DBP) at the time of injection was 25.7 ± 21.0 and 1.3 ± 13.4 mmHg, respectively. A ⩾ 10, ⩾ 20, ⩾ 30 mmHg increase in SBP at the time of injection was seen in 83.8% (n = 253), 69.5% (n = 210) and 49.0% (n = 148) patients, respectively. Forty-one (13.6%) patients developed intra-procedural hypertensive urgency, out of which six patients (14.6%) did not recover even after 1 h of the procedure. None of the patients experienced any cardiovascular events. The univariate and multivariate linear regression analyses showed that the change in intra-procedural SBP correlated positively with the age of the patient and negatively with the baseline SBP. Conclusion: There is a significant rise of SBP at the time of IVI, especially in patients with advanced age and high baseline SBP. Some of the patients can experience hypertensive urgency at the time of injection and may take more than 1 h to recover. The patients receiving IVI should undergo a detailed physician evaluation before the procedure.
RESUMO
PURPOSE: To describe the ocular manifestations of congenital rubella syndrome (CRS), a common cause of congenital cataracts in developing countries. METHODS: Retrospective analysis of case records of 46 sero-positive infants under 12 months of age who presented at Aravind Eye Hospital, Madurai between July 1993 and February 2001. The ocular and systemic examination details were recorded. RESULTS: Both eyes were affected in 41 (89%) patients. Cataract was present in 81 (93.1%) eyes; most of them were nuclear cataract (79, 97.5%). Other common ocular presentations included microphthalmos in 74 (85.1%) eyes, iris abnormalities in 51 (58.6%) eyes, and pigmentary retinopathy in 33 (37.9%) eyes. Cataract, microphthalmos and iris hypoplasia was a common combination present in 49 (56.3%) eyes. Systemic manifestations included cardiac anomalies in 23 (50%) and neurological anomalies in 16 (34%) children. Multi-system involvement was present in 32 (70%) children. Low birth weight (below 2 kg) was seen in 30% infants. CONCLUSION: CRS may present with a wide spectrum of ocular and systemic findings and requires a high index of suspicion for diagnosis. Any sick infant with unilateral or bilateral congenital cataract should be investigated thoroughly for CRS.
