Anquilobléfaro em calopsita(NYMPHICUS HOLLANDICUS): relato de caso

Abstract

The species Nymphicus hollandicus, commonly known as the cockatiel, is one of the most frequently found birds in commercial aviaries. Generally, vision plays a fundamental role in the performance of essential behaviors in birds, such as locomotion, location, acquisition, and sorting of food, as well as predator detection. The ophthalmology of domestic animals can serve as a basis and be adapted for practice in wild and exotic animals, considering that the literature on wild animals is still scarce compared to that of domestic animals. Ankyloblepharon, sometimes referred to as cryptophthalmos by some authors, can be defined as the adhesion of the eyelids to each other and is considered physiological in the first days of the animal's life. However, in some animals, the eyelid opening does not occur or occurs late, thus being classified as pathological ankyloblepharon. The objective of this work is to report a case of ankyloblepharon in a cockatiel. Additionally, it aims to discuss fundamental topics related to the condition within veterinary medicine, correlating the clinical presentation of the patient with reports of this condition in other cockatiels, as well as with recent literature. A cockatiel was presented at the University Veterinary Hospital of the Federal University of Paraíba (UFPB). During the ophthalmological evaluation, it was observed that the eyelids were bilaterally fused. The ocular ultrasound examination revealed no abnormalities in the eyeball. Thus, the patient was diagnosed with ankyloblepharon. Although the condition is observed sporadically in cockatiels, only six reports were found in literature. This study reports the first case of ankyloblepharon in a cockatiel described in the literature to date. Therefore, ankyloblepharon in cockatiels is a condition that should be recognized by veterinarians, with its diagnosis being essential to ensure appropriate management and treatment to minimize impacts on the well being and quality of life of the affected birds. Surgery should be considered as a method to establish vision.
