Study Notes
Ophthalmology Overview
- Tarsal plate stiffens eyelid margins and houses tarsal/meibomian glands, making it ideal for suture retention.
- Distichiasis involves abnormal hair growth along the eyelid edges, with plucking leading to regrowth. Treatment options include electrolysis and cryo-tarso conjunctival resection.
- Entropion is the inward rolling of eyelid margins, potentially aiding vision in nocturnal animals by reflecting light.
- Aqueous humor is continuously produced by the ciliary body, ensuring constant drainage and a watery consistency.
- The vitreous body is a gel-like substance in the eye with no turnover.
- Iris musculature comprises the circular constrictor muscle (parasympathetic control) and radial dilator muscle (sympathetic control).
- Non-lathering povidone-iodine is recommended for ocular disinfection.
- Squamous cell carcinoma is an uncommon lid tumor found in cats, usually presenting as nodular or erosive lesions.
- Cherry eye results from prolapsed nictitating gland, frequently seen in English bulldogs, treated using techniques that preserve gland function.
- Conjunctivitis can present as diffuse reddening with mucopurulent discharge, often associated with chronic dry eye.
Reproductive Physiology
Estrous Cycle
- Pro-oestrus lasts approximately 10 days, followed by a 10-day oestrus phase, a 2-month luteal phase, and concludes with a 4.5-month anoestrus.
Clinical Signs of Estrous
- Signs include reddened/enlarged teats, elevated heart rate, increased appetite, weight gain, and perineal tissue relaxation.
Gestation and Dystocia
- Average gestation length is around 64 days, with dystocia factors categorized as maternal (inadequate expulsion or birthing canal) and fetal (presentation or size issues).
- Plasma relaxin can be detected from day 25, and abdominal palpation showing changes begins around day 21.
Emergency and Critical Care
Triage Principles
- Initial assessment focuses on urgency of treatment based on patient status.
Respiratory Assessment
- Evaluating the airway includes assessing rate, effort, pattern, and mucous membrane color, often aided by a pulse oximeter.
Fluid Therapy
- Signs of fluid deficit vary from none (<5%) to severe (>12% leading to collapse).
- Fluids must be matched to the type of loss and patient needs.
CPR Protocol
- RECOVER guidelines outline essential steps: prevention, basic life support, advanced life support, monitoring, and post-arrest care.
Cardiorespiratory Assessment
Imaging Techniques
- Modalities include radiography, ultrasonography, and CT scanning.
Heart Size Indicators (Dog and Cat)
- Normal heart width in dogs is designed to be 2/3 the width of the thorax in DV view and 2.5-3.5 intercostals in lateral view. Cats may present differently.
Neurology Assessment
Level of Consciousness
- Ranges from normal to comatose, including variations such as dullness or stupor.
Posture and Gait Assessment
- Assess for head tilt, body turn, and various types of gait changes (cerebellar, vestibular, etc.).
Reflex Integrity
- Withdrawal, patellar, and cutaneous trunci reflexes are key to assessing neurologic function.
Dental Procedures
Local Anesthesia Techniques
- Caudal maxillary blocks cover all maxillary branch nerves while inferior alveolar blocks target all mandibular teeth.
