RESUMO
The case report of a 68-year-old man with a single-piece hydrophobic intraocular lens (IOL) implanted in the sulcus with posterior capsular rent in the right eye inducing secondary open-angle pigmentary glaucoma without individual hereditary steroid susceptibility. The clinical and diagnostic evaluations of the patient were thoroughly and specifically carried out. The unilateral pseudophakic open-angle pigmentary glaucoma developed in the long course in the context of rubbing of the haptics and optic of a hydrophobic IOL implanted in the sulcus, against the posterior surface of the iris, resulting in pigment dispersion, trabecular inflammation, and aqueous outflow obstruction. Although the clinical findings of our case were very similar to that of pigmentary glaucoma, the distinction between the two conditions was still quite easy, considering that pigmentary glaucoma is a bilateral disorder predominantly affecting young myopic men with Krukenberg's spindle and increased incidence of steroid responsiveness. It has been clearly distinguished from steroid-induced glaucoma based on the pigmented trabecular meshwork.
RESUMO
BACKGROUND: First case of COVID-19 was reported in December 2019 and within a timespan of few months, it has become a pandemic. It has created havoc globally and India is no exception. Globally, it is emphasized that preventive measures play an important role in controlling the rapid spread of COVID-19. In India, 68% of population is rural and this population is going to play a crucial role in the containment of the pandemic. Realizing the key position of rural population in COVID control, this study was conducted to assess the knowledge, attitude, and practices of rural population about the disease. METHOD AND MATERIAL: A cross-sectional questionnaire-based study was conducted on patients and their relatives from 1st April, 2020 to 31st May, 2020. A total of 372 participants hailing from rural areas were enrolled. RESULTS: Most common source of information for the participants was through television (54.8%) and radio (49.2%). Only 77% claimed that they were using face mask and 72% claimed to be following social distancing. A large (60%) proportion of the participants did not know that COVID-19 could spread from asymptomatic patients. Education of participants was a key determinant for use of social distancing and face mask as a preventive tool. With increasing age, the practice of social distancing and the use of face mask were decreasing in our study. CONCLUSION: Television/Radio channels form an important source of information and need to be used more effectively to educate the people about the disease and create awareness about effective preventive measures. People need to be educated about the role of asymptomatic carriers in spreading the disease.
RESUMO
OBJECTIVES: To evaluate the effect of prolonged duration of prone position (with head laterally rotated) on intraocular pressure in acute respiratory distress syndrome patients. DESIGN: Prospective observational study. SETTING: University hospital ICU. PATIENTS: Twenty-five acute respiratory distress syndrome patients, age 60 years (51-67 yr), Sequential Organ Failure Assessment score 10 (10-12), PaO2/FIO2 ratio of 90 (65-120), and all in septic shock. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Intraocular pressure (in mm Hg) measured by hand-held applanation tonometer, at different time points. Before prone (in both eyes): at 30-45° head-end elevation position (THE pre-prone), in supine position just before turning prone (Tsupine pre-prone); during prone (in nondependent eye): at 10 minutes (T10 prone), 30 minutes (T30 prone), and at just before end of prone session (Tend-prone). After end of prone session (both eyes): at 5 minutes (T5 supine post-prone), 10 minutes (T10 HE post-prone), 15 minutes (T15 HE post-prone), and 30 minutes (T30 HE post-prone). Median duration of prone position was 14 hours (12-18 hr). Median intraocular pressure increased significantly (p ≤ 0.001) in both eyes. In dependent eye, from 15 (12-19) at THE pre-prone to 24, 21, 19, and 16 at T5 supine post-prone, T10 HE post-prone, T15 HE post-prone, and T30 HE post-prone respectively, whereas in nondependent eye from 14 (12-18.5) at THE pre-prone to 23, 25, 32, 25, 22, 20, and 17 at T10 prone, T30 prone, Tend-prone, T5 supine post-prone, T10 HE post-prone, T15 HE post-prone, and T30 HE post-prone respectively. Bland-Altman plot analysis showed significant linear relationship (r = 0.789; p ≤ 0.001) with good agreement between rise in mean intraocular pressure of the both eyes (dependent eye and nondependent eye) with their paired differences after the end of different duration of prone session (T5 supine post-prone). CONCLUSIONS: There is significant increase in intraocular pressure due to prone positioning among acute respiratory distress syndrome patients. Intraocular pressure increases as early as 10 minutes after proning, with increasing trend during prone position, which persisted even at 30 minutes after the end of post prone session although with decreasing trend.
