A 54-year-old man with noncontributory medical history presented to an ophthalmologist in January 2022 after 10 days of irritation in his right eye. The patient recounts having felt something get into his eye and under his contact lens (CL) while he was climbing into his car, but he was unsure what the foreign body may have been. Initial examination by the clinician found uncorrected distance visual acuity of 20/100-2 with a corneal abrasion, 4+ corneal edema, and 3+ conjunctival injection, for which he was placed on topical antibiotics (ocuflox and tobradex) with a bandage CL. 1 week later, visual acuity was 20/80, corneal edema had improved, and he was noted to have corneal scarring and an epithelial defect. Tobradex was continued while prednisolone drops and preservative-free artificial tears were started. 1 week later, the patient had worsening visual acuity to 20/250 and was referred to our tertiary center. On initial consultation, the patient had an uncorrected distance visual acuity of 20/500 and an uncorrected near visual acuity of >J10 in the right eye. Slitlamp examination of the right eye was significant for vortex keratopathy and mild corneal pannus with 360-degree subtle conjunctivalization of the limbus ( Figure 1JOURNAL/jcrs/04.03/02158034-202210000-00022/figure1/v/2022-10-03T121249Z/r/image-tiff ). The corneal topograph was obtained showing significant surface irregularity on the Placido image ( Figure 2JOURNAL/jcrs/04.03/02158034-202210000-00022/figure2/v/2022-10-03T121249Z/r/image-tiff ). Examination of the left eye was unremarkable. The ocular history is significant for myopia of -4.0 diopters and CL use for 20 years. The patient admits to regularly wearing soft CLs for several days straight and only removing them for a few hours. Antibiotics were discontinued, corticosteroid drops were reduced in frequency, and the patient was continued on preservative-free artificial tears. What imaging might you consider? What is your differential diagnosis at this point? What would be the most appropriate surgical and/or medical interventions? What would you counsel in prognosis for this patient?

PrcisTracking failure frequency (TFF) increases with dry eye symptom severity and in the left eye.PurposeSymptoms of dry eye disease are commonly encountered in glaucoma patients and can be exacerbated by topical glaucoma medications. Dry eye disease may influence the reliability of visual field (VF) tests and impact the accurate interpretation of the results.Patients and methodsPatients at the Veterans Administration Medical Center San Diego completed the 5-item Dry Eye Questionnaire before VF testing between December 2018 and February 2019. VF reliability metrics were recorded for each patient. Standard reliability metrics included fixation losses, false positive, and false negative rates. Gaze tracking (GT) metrics included percent of stimuli with gaze deviations between 1 and 2 degrees, 3 and 5 degrees, 6 degrees or greater, and percent of stimuli with tracking failure (TFF). The use of glaucoma medications and artificial tears was also recorded.ResultsA total of 494 patients completed the 5-item Dry Eye Questionnaire and VF testing. There was no association between dry eye symptom severity and standard reliability metrics or most GT metrics. However, TFF increased as dry eye symptom severity increased (P=0.015). TFF was also greater in the left eye, which was tested second (P=0.012); no other reliability metrics were related to laterality. Patients were more likely to use artificial tears with increased dry eye symptom severity (P

ABSTRACT This report was aimed at presenting a case of neurotrophic keratitis and concomitant SARS-CoV-2 infection in a patient who has recently undergone a corneal DALK transplant. One month after corneal transplantation with adequate corneal epithelialization, the patient presented neurotrophic keratitis with a torpid course of the corneal transplant coinciding with a SARS-CoV-2 infection, with an excessive host immune response. In addition, the patient presented a re-positivization of nasopharyngeal polymerase chain reaction of SARS-CoV-2 with past disease after starting treatment with autologous serum eye drops. The implications at the ophthalmological level of SARS-CoV-2 infection may be clarified as the time the illness progresses and we learn more about how it acts. In this case, the disparity of signs and symptoms, the antecedent of corneal surgery, and the possibility of a herpetic infection as a cause of the primary leukoma suggested neurotrophic keratitis. Nonetheless, the involvement of systemic SARS-CoV-2 infection in the process, triggering an excessive host immune response at the corneal level with an increase in inflammatory cytokines must be taken into account. No relationship was found between treatment with autologous serum and re-positivization of nasopharyngeal polymerase chain reaction, presenting the patient a favorable response to treatment.
