Background Enucleation and exenteration are widely utilized ophthalmic procedures in veterinary practice, involving the complete removal of the eye and comprehensive extraction of orbital contents, respectively. These procedures are indicated for pain relief, excision, and management of neoplasia metastases, and addressing severe medically untreatable conditions. Aim This study aimed to develop an orbital enucleation surgical approach. The study evaluated the applicability of the new approach and investigated the impact of the surgical procedure. Methods Anatomical dissection of three cadaveric heads and surgical orbital enucleation in four cadaveric heads were performed. Anatomical data was collected, and feasibility, safety and applicability of the procedure were assessed. Results Anatomical dissection showed a distinctive large orbital fossa, providing a suitable surgical window to access orbital structures. The procedure was found to be feasible, facilitating the complete removal of the orbital content. Notably, the preservation of intact eyelids was prioritized to enhance cosmetic appearance. Conclusion The presented orbital enucleation technique proved to be feasible, safe, reproducible, and required basic surgical skills to perform.

Enucleation and exenteration are widely utilized ophthalmic procedures in veterinary field. Enucleation in camels is like other large animals, typically performed under the influence of heavy sedation and loco-regional analgesia. The aim of the current study was to introduce a new surgical approach to enucleate the eye of camels through supraorbital fossa approach. for that purpose, the technique was applied to seven camels referred to the King-fisal teaching veterinary hospital for unilateral enucleation. Assessment of applicability, safety and feasibility of this technique was done. All procedures were performed in the kush (sitting) position under the influence of heavy sedation with Xylazine HCl in combination with retrobulbar nerve block. A "C" shaped skin incision was made in the skin and fascia of the supraorbital fossa to enter the orbital cavity, after which the periorbital fat was gripped, dissected and removed. Bleeding controlled by electrocautery and visible large blood vessels were ligated. After ligation the optic nerve and ophthalmic blood vessels, the eyeball was dissected sharply and freed from the orbital bony attachment. Finally, the orbital fascia and skin were sutured with simple interrupted pattern separately. The approach proved successful in all camels, with the enucleation procedure being both feasible and easily performed. The mean surgical time was approximately 46.6±12.4 minutes. The minimal occurrence of short and long-term complications was encouraging, and the cosmetic outcomes were notably improved. The supraorbital approach is a safe and effective technique for camel ophthalmic surgery, showing advantages in exposure and minimal complications. Further research is needed for validation and broader clinical applications.

The fusion of biomaterial science with clinical practice in oculoplastic and orbital surgery, particularly in the reconstruction of the posterior lamella of the eyelid, the lacrimal system, orbital floor fractures, and the development of implants for anophthalmic sockets, represents a frontier where materials meet surgical techniques. This review, which spans research from 2015 to 2023, delves into the application and integration of biopolymers and functional biomaterials in these complex areas. The discussion begins by reviewing the key anatomy of the external ocular surface, lacrimal system, and orbit. It then summarizes the various current surgical approaches for treating diseases affecting the external ocular surface and orbital involvement, with an emphasis on the associated challenges. The discussion continues with a comprehensive overview of the advantages and disadvantages of current and emerging biomaterials, including synthetic and natural polymers, used in reconstructive surgeries. These include applications for eyelid structure reconstruction, lacrimal system repair, orbital bone fracture repair, and orbital socket reconstruction. Throughout the review, the pathophysiology and challenges associated with these reconstructive procedures are explored, with an emphasis on surgical nuances and the ongoing pursuit of optimal reconstruction techniques. Finally, this review serves as a valuable resource for familiarizing clinicians with current knowledge and generating future hypotheses. It concludes that no evidence-based guidelines currently exist in oculoplastic surgery regarding the use of biopolymers in reconstructive procedures. Further research is needed to evaluate the efficacy and reproducibility of these biopolymers.
