Among 225 eyes (149 dogs), 110 eyes were randomly selected for prechop phacoemulsification with the specific prechopper, and 115 eyes for stop-chop phacoemulsification. Surgical outcomes, including CDE, postoperative aqueous flare and complications, were evaluated.Results: The prechop group demonstrated less mean CDE and postoperative aqueous flare incidence compared to the stop-chop group (53.93 ± 15.29 vs. 78.32 ± 21.32, p < 0.001; 35.14% vs. 58.59%, respectively). The prechop group had fewer overall complications than the stop-chop group (35.2% vs. 56.7%). Vision retention rates at final follow-up (30-1440 days postoperation) were comparable (prechop: 95.7% vs. stop-chop: 92.9%), but glaucoma incidence was lower in the prechop group than in the stop-chop cohort (5 vs. 3 eyes). CDE correlated strongly with complication severity.Conclusions: The prechop technique with a novel prechopper offers a safer, more efficient alternative for phacoemulsification of canine cataracts, particularly in eyes requiring high energy nuclear fragmentation.","PeriodicalId":23836,"journal":{"name":"Veterinary ophthalmology","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145471844","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}

IOPs were measured in the clinic after the ophthalmic examination, and in the home upon initial entry by the observer (t = 0) and 10 min later (t = 10).

Baseline corneal touch thresholds (CTT, cm) were measured via esthesiometry and a subconjunctival injection was performed in the treatment eye with ropivacaine (R, 0.3 mL 0.5%) or dexmedetomidine-ropivacaine (DR, 0.1 mL 0.5 mg/mL + 0.2 mL 0.5%) and saline (control, 0.3 mL) in the contralateral eye.

Aspergillus fumigatus and Fusarium solani isolates were inoculated in fresh bovine corneoscleral transplants, superficially or at 450 μm of stromal depth for the ulcerative keratomycosis or stromal abscess model, respectively. After a minimum of 18 h of incubation, treatment groups received 15 s of UV-C light exposure at a 10 mm distance from the corneal surface level (22.5 mJ/cm2 dose). Fungal inactivation was quantified by determining the mean fluorescent intensity (MFI) of two fungal viability markers (SYTO 9 = green = alive; PI = red = dead) utilizing confocal laser scanning microscopy.Results: UV-C treatment resulted in statistically significantly higher MFI-PI, lower MFI-SYTO 9 and lower normalized MFI ratios (SYTO 9/[SYTO 9 + PI]) compared to controls for both isolates irrespective of corneal depth; therefore demonstrating successful fungal inactivation. In superficial location, fungal inhibition reached 88% for both isolates. At deeper corneal depth, fungal inhibition was not significantly different for F. solani (84%) but significantly less complete for A. fumigatus (60%).Conclusions: Corneal UV-C light treatment may offer therapeutic benefits for ulcerative keratomycosis and stromal abscesses in the equine species using doses expected to be safe for corneal exposure based on previously published safety data. Species-specific safety studies are required to ensure that antifungal efficacy aligns with safe clinical practice.","PeriodicalId":23836,"journal":{"name":"Veterinary ophthalmology","volume":" ","pages":"e70110"},"PeriodicalIF":1.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12963518/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145764067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each dog was treated with diamond burr debridement (DBD) and then randomized into one of two groups. One group was treated with topical antiseptic (Septostil, SG) four times daily (QID), and the other group was treated with topical cefazolin QID (CG). Follow-up was performed at 1 (T1), 2 (T2), and 4 (T3) weeks after DBD, and success was considered when re-epithelialization occurred after DBD.Results: In total, 104 eyes were included. Fifty eyes were treated with cefazolin and 54 with antiseptic. The success rates were 94.4% (51/54) in the SG (95% confidence interval [CI], 84.9%-98.1%) and 92% (46/50) in the CG (95% CI, 81.2%-96.8%), with no statistical difference (p = 0.708).

Skull conformation and previous antibiotics or anti-inflammatory drugs before DBD did not influence epithelial healing time, whereas female participants showed faster healing times than male participants.Conclusions: Septostil did not show significant differences in terms of re-epithelialization or healing time compared with antibiotics. The application of antiseptic eye drops could represent a promising approach for topical prophylactic treatment following SCCEDs in dogs; however, these findings are preliminary, and larger studies are needed to draw definitive conclusions.","PeriodicalId":23836,"journal":{"name":"Veterinary ophthalmology","volume":" ","pages":"e70114"},"PeriodicalIF":1.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145574477","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}

The alternate solution was administered in the same nostril 2 weeks later. Schirmer tear test-1 (STT-1) was performed bilaterally before and 15 min after nasal administration. Tear strip wetting was recorded every 10 s for 60 s; the initial uptake phase (0-10 s) reflected uptake of pre-existing tears, while the active secretion phase (10-60 s) represented reflex tearing.

Four different feline eyes with focal corneal edema were cannulated ex vivo and tonometry readings obtained from clear and edematous cornea at set manometric IOPs from 5 to 70 mmHg.Results: Rebound tonometry values were 4.0 ± 5.5 (SD) mmHg lower, and TP values were 13.0 ± 5.9 (SD) mmHg higher in regions of edema versus clear cornea in the same eye (p = 0.0075). Relative to manometry, TVP and TV01 accuracy and precision were acceptable for clear cornea readings but were negatively impacted by corneal edema. TP-derived readings grossly underestimated high IOPs relative to manometry in both clear and edematous feline cornea and were significantly less accurate than rebound tonometers in clear cornea (p = 0.03).
