ABSTRACT

Purpose: To compare the post-cataract endophthalmitis (PCE) rates among eyes undergoing syringing or regurgitation on pressure over the lacrimal sac (ROPLAS) test prior to cataract surgery. Methods: We performed a single-center, retrospective, comparative analysis of eyes developing PCE who underwent syringing prior to cataract surgery (group A) in the pre-COVID-19 era between November 1 2019 and January 31, 2020 and the eyes that underwent ROPLAS test prior to cataract surgery (group B) in the COVID-19 era between November 1, 2020 and January 31, 2021. Results: A total of 87,144 eyes underwent cataract surgery during the two time periods of the study. Syringing was performed in 48,071 eyes, whereas ROPLAS was performed in 39,073 eyes. In group A, 19 eyes (0.039%) developed PCE, whereas 20 eyes (0.051%) developed PCE in group B (P = 0.517). Between the two groups, the grade of anterior chamber cellular reaction (P = 0.675), hypopyon (P = 0.738), and vitreous haze (P = 0.664) were comparable. Gram-positive organisms were detected in 4 eyes in group A and 6 eyes in group B; 2 eyes in group A had gram-negative bacilli. The presenting visual acuity (Group A: LogMAR 1.42 and Group B: LogMAR 1.30) and final visual acuity (Group A: LogMAR 0.52 and Group B: LogMAR 0.5) were comparable between the two groups. (P = 0.544 and 0.384, respectively). Conclusion: The rates of PCE were comparable among the eyes undergoing either syringing test or ROPLAS prior to cataract surgery.

ABSTRACT

PURPOSE: To evaluate the role of viral infections in the pathogenesis of primary acquired nasolacrimal duct obstruction. METHODS: The study included 48 patients diagnosed with primary acquired nasolacrimal duct obstruction undergoing dacryocystorhinostomy surgery. Prior to dacryocystorhinostomy surgery, nasal swab sample was taken from the inferior meatus at the same side. During dacryocystorhinostomy, tissue biopsy sample (2 × 2 mm) was taken from the junction area of the lacrimal sac and nasolacrimal duct. Following nucleic acid extraction, polymerase chain reaction was performed. RESULTS: The patients consisted of 9 (18.8%) men and 39 (81.2%) women with a mean age of 51.0 ± 14.3 years. Qualitative polymerase chain reaction showed viral genome in the nasal swabs of 10 (20.8%) patients, including coronavirus 229E (three cases), coronavirus HKU1 (two cases), respiratory syncytial virus (two cases), coronavirus OC43 (one case), coronavirus NL63 (one case), and adenovirus (one case). In the dacryocystorhinostomy samples, viral genomes were detected in four (8.3%) cases, including respiratory syncytial virus (two cases), coronavirus HKU1 (one case), and adenovirus (one case). There was a statistically significant agreement between nasal mucosal swab and dacryocystorhinostomy biopsy samples in terms of respiratory syncytial virus positivity (kappa = 1.000, p = 0.001). CONCLUSION: Although the viral genome was detected in the samples, a direct relationship between viruses and pathogenesis of primary acquired nasolacrimal duct obstruction could not be revealed because of the low number of positive results. However, considering the profibrotic characteristics of specific viruses such as respiratory syncytial virus and adenovirus, viral infections may be one of the many predisposing factors of primary acquired nasolacrimal duct obstruction.

ABSTRACT

PURPOSE: To perform a systematic analysis of articles on the ophthalmological implications of the global COVID-19 pandemic. METHODS: PubMed.gov was searched for relevant articles using the keywords "COVID-19", "coronavirus", and "SARS-CoV-2" in conjunction with "ophthalmology" and "eye". Moreover, official recommendations of ophthalmological societies were systematically reviewed, with a focus on the American Academy of Ophthalmology (AAO) and the Royal College of Ophthalmologists (RCOphth). RESULTS: As of April 16, 2020, in total, 21 peer-reviewed articles on the ophthalmological aspects of COVID-19 were identified. Of these, 12 (57.1%) were from Asia, 6 (28.6%) from the United States of America, and 3 (14.3%) from Europe. There were 5 (23.8%) original studies, 10 (47.6%) letters, 3 (14.2%) case reports, and 3 (14.2%) reviews. These articles could be classified into the topics "Modes and prevention of (ocular) transmission", "Ophthalmological manifestations of COVID-19", "Clinical guidance concerning ophthalmological practice during the COVID-19 pandemic", and "Practical recommendations for clinical infrastructure". Practical recommendations could be extracted from official statements of the AAO and the RCOphth. CONCLUSION: Within a short period, a growing body of articles has started to elucidate the ophthalmological implications of COVID-19. As the eye can represent a route of infection (actively via tears and passively via the nasoacrimal duct), ophthalmological care has to undergo substantial modifications during this pandemic. In the eye, COVID-19 can manifest as keratoconjunctivitis.
