Purpose: To investigate the in vivo sutureless vitrectomy incision architecture using optical coherence tomography (OCT) in the immediate postoperative period.
Design: Prospective, observational case series.
Participants: Thirty-five patients underwent 3-port pars plana vitrectomy using 23-gauge instrumentation combined with 25-gauge infusion at the Wenzhou Eye Hospital.
Methods: All incisions were evaluated using the Carl Zeiss Visante (Dublin, CA) anterior segment OCT imaging system within 5 hours postoperatively.
Main Outcome Measures: Wound architecture (e.g., the length and angle of the incision, presence of gaping), and presence of ciliochoroidal detachment and vitreous incarceration. Seidel test and intraocular pressure (IOP) measurements were performed immediately afterward. Surgical parameters were also recorded.
Results: The mean incision length was 1.15 ± 0.22 mm (range, 0.80-1.55). The mean incision angle was 54.6 ± 13.0 degrees (range, 28.6-80.7). No difference in incision length or angle was found between different quadrants or between 25-gauge and 23-gauge instrumentation. The presence of internal or external gaping and misalignment of the roof and floor of the incisions accounted for 38.1% loss of wound apposition in a bidimensional image. Four eyes (11.4%) had shallow local ciliochoroidal detachments and 2 eyes (5.7%) had minimal vitreous incarceration. The mean postoperative IOP was 12.1 ± 6.2 mmHg (range, 3.5-28.0). The IOP was significantly higher in eyes with good wound apposition as opposed to those with loss of wound apposition (P = 0.011). Of the 4 eyes with hypotony, only 1 presented with leakage, as demonstrated by a positive Seidel test, and incision gaping, as shown by OCT imaging.
Conclusions: The architectural features of gaping, misalignment, and great variation in incision angle on OCT theoretically reduce the security of sutureless sclerotomy in the immediate postoperative period. These features presumably predispose the patient to lower IOP and greater risk of wound leakage.

Veterinary intervention in zoological species can be complicated by species-specific social dynamics. African wild dogs are a pack species and removal or separation of an individual may disrupt established pack hierarchy resulting in conspecific aggression. Therefore, medical interventions that optimize a quick return to health are ideal to minimize the duration of absence from the pack.

Objective: To describe clinical presentation, concurrent injuries, common imaging findings, and short-term outcome of dogs and cats diagnosed with prepubic hernia (PPH).
Animals: 71 dogs and 16 cats.
Clinical Presentation: Medical records were searched at 2 academic referral institutions from August 1, 2008, to August 31, 2023, for dogs and cats diagnosed with PPH.
