Abnormalities were photographed. Normative values for Schirmer tear test-1 (STT-1), applanation tonometry, aerobic and anaerobic bacterial culture, fungal culture, and transcorneal ocular ultrasonography were derived from multiple cohorts of clinically normal adult birds. Five birds with ocular pathology also underwent transcorneal ultrasonography. Statistical comparisons for normative values between OD and OS, and males and females were made using a paired t-test or Mann-Whitney U-test, with a significance level of p < .05.Results: Mean tear production based on Schirmer tear test 1 (STT-1) was 10.16 ± 4.61 mm/min (3-21 mm/min). Mean intraocular pressure (IOP) was 12.42 ± 4.94 mm Hg (5-26 mm Hg). Staphylococcus species were the most isolated bacteria from the conjunctival surfaces of normal birds (85%). Significant differences were found in transcorneal ultrasonographic measurements between males and females for axial globe length (p = .032), vitreous body depth (p = .049) and lens thickness (p = .0428). Corneal fibrosis was the most observed ocular abnormality amongst eyes with pathological changes (39%).Conclusions: Schirmer tear testing, tonometry and transcorneal ultrasound can easily be utilized in MacQueen's bustards and provide reproducible results.

Extranodal lymphomas include lymphomas in ocular and periocular tissues, such as the third eyelid (TEL), which is an uncommonly diagnosed type of lymphoma in cats. This study aimed to describe the clinicopathological features of lymphoma in the TEL of two FeLV-infected cats. A retrospective study in two anatomic pathology laboratories was performed, and two cases met the inclusion criteria. A 4-year-old, female cat (case 1), positive for FIV gp40 antigen and FeLV gp70 antigen by immunohistochemistry (IHC), and a male cat of 22 months old (case 2), positive both serologically for FeLV p27 antigen and for FeLV gp70 antigen by IHC, were referred to veterinary clinics with unilateral swelling and mass in the TEL, which had rapid growth in case 2. Histological and immunohistochemical analysis established the final diagnosis of diffuse large B-cell lymphoma in both cases. The cat in case 2 died 4 months after the diagnosis, with clinical worsening prior to death. Necropsy was not performed in either case, which precluded the definition of a primary or secondary involvement. However, the ocular lesions were the reason for consultation in both cases and it may have been an initial manifestation of a multicentric disease. Thus, FeLV-infected cats with clinical finding of eyelid swelling or mass formation should have lymphoma as a differential diagnosis, and a complete physical examination should be performed to detect extraocular involvement.","PeriodicalId":23836,"journal":{"name":"Veterinary ophthalmology","volume":" ","pages":"640-645"},"PeriodicalIF":1.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141155416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AT at temperatures of 2°C, 20°C, and 38°C, and a high-viscosity tear gel of 20°C, were topically instilled in 100 μL volumes. SD-OCT tracked LC width changes following each instillation.Results: The average baseline width of the LC was 96.38 ± 30.18 μm. The 2°C AT expanded LC width to 183.50 ± 44.11 μm, returning to baseline in 5.00 ± 1.31 min. The 20°C AT resulted in a width of 155.25 ± 35.79 μm, with a 3.88 ± 1.25 min return. The 38°C AT expanded LC width to 131.75 ± 29.49 μm, with a 2.25 ± 0.89 min return. The high-viscosity tear gel expanded LC width to 208.57 ± 56.31 μm, with remained expanded for 10 or more minutes. In temperature comparisons, the 2°C and 20°C AT significantly expanded the LC width more and had longer return times than the 38°C AT (p < .05). Viscosity comparisons showed higher viscosity eye drops significantly expanded LC width more than lower viscosity eye drops (p < .05).Conclusions: This study found that lower temperature and higher viscosity of eye drops had tendency to result in a wider expansion of the LC width. Additionally, the return time to baseline for LC width tended to be longer with eye drops of lower temperature and higher viscosity. This finding could be helpful in advancing future research on tear dynamics.","PeriodicalId":23836,"journal":{"name":"Veterinary ophthalmology","volume":" ","pages":"583-592"},"PeriodicalIF":1.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141432945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the information on biological properties and alternative forms of cAM for corneal wound healing is limited. This study aimed to investigate the proteomic profiles and corneal wound healing properties of cAM, cAM extract (cAME), and lyophilized cAM extract (cAMX).Animal studied: A total number of 14 cAMs were sterilely harvested from healthy full-term puppies and randomly divided into three different forms: cAM (n = 14), cAME (n = 14), and cAMX (n = 14).Procedures: Each form of cAMs was subjected to proteomic analysis using label-free liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS), followed by bioinformatic analysis. The proteins were classified into properties by comparing them with the literature search on human amniotic membrane (hAM) properties and the effect on corneal wound healing when given topically.Results: The analyses identified 8136 proteins in cAM, 8211 proteins in cAME, and 7093 proteins in cAMX. A total number of 100 proteins were matched with proteins in hAM properties and were classified into anti-inflammatory, anti-fibrotic, anti-microbial, anti-angiogenic, promotion of epithelialization, analgesic, and support cell adhesion and growth properties. Furthermore, proteins with corneal wound healing effects were identified in cAME and cAMX.Conclusions: cAM and its extracts contain numerous proteins, including proteins related to corneal wound healing properties. Additionally, cAME and cAMX showed proteins involved in corneal wound healing and their potential benefits for topical use in ophthalmology.","PeriodicalId":23836,"journal":{"name":"Veterinary ophthalmology","volume":" ","pages":"593-604"},"PeriodicalIF":1.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141856637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
