RESUMO

BACKGROUND: The aim of this report is to describe the risk factors, clinical course, and characteristics of three cases of Paecilomyces keratitis presenting concurrently within three months in the same location. We used in vivo confocal microscopy and histopathology to corroborate our clinical findings. OBSERVATIONS: Three eyes of three elderly patients with culture-proven Paecilomyces keratitis were included in this series. These patients resided within a 15-mile radius and presented to a tertiary care eye institute in Southern California between February and April 2022. All three eyes experienced a prolonged, recalcitrant course with recurrence of keratitis in donor corneal tissue despite antifungal therapy and multiple therapeutic penetrating keratoplasties. In vivo confocal microscopy, histopathology, and microbiologic findings corroborated the diagnosis of fungal keratitis with Paecilomyces. With surgical intervention and extensive medical therapy, all three cases resolved after the addition of oral Posaconazole. CONCLUSIONS: Paecilomyces is a rare cause of infectious keratitis. Herein we report three similar cases in elderly patients. All had prolonged, recalcitrant infections that required multiple treatment modalities. Our cases, which were supported by in vivo confocal microscopy and histopathology, highlight the importance of timely and aggressive therapy to prevent recurrence.

RESUMO

Purpose: To elucidate risk factors for meibomian gland disease (MGD) and understand associated changes in meibography and in relation to ocular surface disease. Patients and Methods: As part of the standard workup for ocular surface disease at a tertiary academic center, 203 patients received an ocular history and lifestyle questionnaire. The questionnaire included detailed inquiries about ocular health and lifestyle, including makeup use, cosmetic eyelid procedures, screen time, and contact lens habits. Subjects also took the standardized patient evaluation of eye dryness (SPEED) II questionnaire. Meibomian gland (MG) dropout and structural changes were evaluated on meibography and scored by three independent graders using meiboscores. Statistical analysis was conducted to identify significant risk factors associated with MG loss. Results: This retrospective, cross-sectional study included 189 patients (378 eyes) with high-quality images for grading, and the average age was 67 years (77% female). Patients older than 45 years had significantly more dropout than younger patients (p < 0.01). Self-reported eye makeup use did not significantly impact MG loss. Patients with a history of blepharoplasty trended toward higher meiboscores, but the difference was not statistically significant. Self-reported screen time did not affect meiboscores. Contact lens use over 20 years was associated with significant MG loss (p < 0.05). SPEED II scores had no relationship to meiboscores (p = 0.75). Conclusion: Older age is a significant risk factor for MG loss. Any contact lens use over 20 years also impacted MG dropout. Highlighting the incongruence of symptoms to signs, SPEED II scores showed no relationship to the structural integrity of MGs.

RESUMO

PURPOSE: To analyze and compare the tear immunological profile in ocular GVHD (oGVHD) patients with that in non-oGVHD patients and to correlate them with ocular surface parameters based on the International Chronic Ocular GVHD Consensus Group (ICCGVHD) diagnostic criteria. METHODS: Tear samples from 20 individuals who underwent allo-hematopoietic stem cell transplantation and were grouped according the presence or absence of oGVHD were analyzed using Bio-Plex assay. RESULTS: IL-8 and MIP-1α levels were significantly higher in tears from oGVHD patients compared with those in tears from non-oGVHD patients (p<0.001 and p=0.001, respectively). Tear IL-8 levels correlated significantly with OSDI criteria (ρ=0.5159, p=0.001), ocular hyperemia (ρ=0.469, p=0.002), and corneal staining (ρ=0.339, p=0.032), whereas tear Mip-1α levels correlated with OSDI score (ρ=0.358, p=0.023). CONCLUSION: We demonstrated higher tear levels of IL-8 and MIP-1α in oGVHD patients and significant correlations between theses cytokines and ocular surface parameters based on the ICCGVHDCG criteria.
