This article is published with open access Abstract Blepharoptosis (ptosis) is among the most common disorders of the upper eyelid encountered in both optometric and ophthalmic practice. The unilateral or bilateral drooping of the upper eyelid that characterises ptosis can affect appearance and impair visual function, both of which can negatively impact quality of life. While there are several known forms of congenital ptosis, acquired ptosis (appearing later in life, due to a variety of causes) is the predominant form of the condition. This review summarises the prevalence, causes, identification, differential diagnosis, and treatment of acquired ptosis. Particular attention is paid to the differential diagnosis of acquired ptosis and emerging treatment options, including surgical and pharmacologic approaches. 1234567890();,: 1234567890();,: Literature search notes either congenital (present at or shortly following birth) or acquired (appearing later in life).

Older adults are at a higher risk of developing dry eye disease as well as needing for ophthalmic surgery. Anterior segment surgery may induce or worsen existing dry eye symptoms usually for a short-term period. Despite good visual outcomes, ocular surface dysfunction can significantly affect quality of life and, therefore, lower a patient’s satisfaction with ophthalmic surgery. Preoperative dry eye disease, factors during surgery and postoperative treatment may all contribute to ocular surface dysfunction and its severity. We reviewed relevant articles from 2010 through to 2021 using keywords “cataract surgery”, ”phacoemulsification”, ”refractive surgery”, ”trabeculectomy”, ”vitrectomy” in combina- tion with ”ocular surface dysfunction”, “dry eye disease”, and analyzed studies on dry eye disease pathophysiology and the impact of anterior segment surgery on the ocular surface.

  • BOSTON TERRIER EYE DISEASE Corneal Ulcers and Prevention
    BOSTON TERRIER EYE DISEASE Corneal Ulcers and Prevention Corneal Ulcers are the single largest eye problem in Boston Terriers. Perhaps 1 dog in 10 will experience a corneal ulcer sometime during its life based on the l903 dogs surveyed in the 2000 Boston Terrier Health Survey. The Boston Terrier Standard for the Breed calls for eyes to be “wide apart, large and round and dark in color. The eyes are set square in the skull and the outside corners are on a line with the cheeks as viewed from the front". The ideal Boston Terrier eye does not protrude but is "set square in the skull". Unfortunately the Boston eye is fairly prone to eye injury because of its large size and prominence. Corneal ulcers are caused initially by injury to the eyes. The common practice of removing Boston Terrier whiskers may be a reason that eyes become injured due to lack of sensory feelers. Some breeders do not trim whiskers once a dog's show career is finished because they know that whiskers can prevent injury to the eye. There are a number of external reasons why an injured eye doesn't heal. These may include irritation from eyelashes or from facial hairs, infection, and lack of moisture in the eye. Some of these reasons are hereditary. Internal reasons for an eye not healing include glaucoma and infection. Corneal ulcers can be difficult and expensive to treat and often result in the loss of the eye. This is a case where an "ounce of prevention is worth a pound of cure".

The inheritance is autosomal dominant with high penetrance but variable expressivity. Here we describe a mutational analysis of 27 Danish patients using a dideoxy fingerprinting method, which identified PAX6 mutations in 18 individuals with aniridia. A thorough phenotype description was made for the 18 patients. A total of 19 mutations, of which 16 were novel, are described. Among these were five missense mutations which tended to be associated with a milder aniridia phenotype, and in fact one of them seemed to be non-penetrant. Four of the five missense mutations were located in the paired domain. We also describe a third alternative spliced PAX6 isoform in which two of the four missense mutations would be spliced out. Our observations support the concept of dosage effects of PAX6 mutations as well as presenting evidence for variable expressivity and gonadal mosaicism.

  • Visual Impairment Age-Related Macular
    VISUAL IMPAIRMENT AGE-RELATED MACULAR DEGENERATION Macular degeneration is a medical condition predominantly found in young children in which the center of the inner lining of the eye, known as the macula area of the retina, suffers thickening, atrophy, and in some cases, watering. This can result in loss of side vision, which entails inability to see coarse details, to read, or to recognize faces. According to the American Academy of Ophthalmology, it is the leading cause of central vision loss (blindness) in the United States today for those under the age of twenty years. Although some macular dystrophies that affect younger individuals are sometimes referred to as macular degeneration, the term generally refers to age-related macular degeneration (AMD or ARMD). Age-related macular degeneration begins with characteristic yellow deposits in the macula (central area of the retina which provides detailed central vision, called fovea) called drusen between the retinal pigment epithelium and the underlying choroid. Most people with these early changes (referred to as age-related maculopathy) have good vision. People with drusen can go on to develop advanced AMD. The risk is considerably higher when the drusen are large and numerous and associated with disturbance in the pigmented cell layer under the macula. Recent research suggests that large and soft drusen are related to elevated cholesterol deposits and may respond to cholesterol lowering agents or the Rheo Procedure. Advanced AMD, which is responsible for profound vision loss, has two forms: dry and wet. Central geographic atrophy, the dry form of advanced AMD, results from atrophy to the retinal pigment epithelial layer below the retina, which causes vision loss through loss of photoreceptors (rods and cones) in the central part of the eye.

  • Clinical Signs of Brachycephalic Ocular Syndrome in 93 Dogs Joana Costa1* , Andrea Steinmetz2 and Esmeralda Delgado3
    Costa et al. Irish Veterinary Journal (2021) 74:3 https://doi.org/10.1186/s13620-021-00183-5 RESEARCH Open Access Clinical signs of brachycephalic ocular syndrome in 93 dogs Joana Costa1* , Andrea Steinmetz2 and Esmeralda Delgado3 Abstract Background: Brachycephalic breeds have anatomical skull changes that are responsible for ocular clinical signs, known as the brachycephalic ocular syndrome (BOS). Their popularity has increased in recent years but the excessive pressure of selection lead to extreme conformation of skull shapes, resulting in facial alterations that can put these dogs’ vision at risk. Objectives: This study aimed to analyse the ocular disorders in a sample of 93 brachycephalic dogs to better characterize the disease complex BOS. Material and methods: Brachycephalic dogs were submitted to a complete ophthalmological examination. The studied parameters included animal’s sex, age and breed, age, ophthalmological tests performed, results of complementary exams, clinical signs, ocular disorders, treatment protocols and their outcomes. Data were organized using Microsoft Office Excel 2007® and statistical analysis was performed with IBM SPSS Statistics 20®. Results: The studied population included 93 brachycephalic dogs 45 males (48%) and 48 females (52%) from different breeds: French Bulldog (n = 38), Shih-Tzu (n = 22), Pug (n = 17), English Bulldog (n = 5), Pekingese (n = 4), Boxer (n = 4) and Boston Terrier (n = 3), aged between 0.2–16 years, median 4.65 years. The most frequent ocular abnormalities were corneal ulcers in 44%, corneal pigmentation in 36%, corneal fibrosis in 25% and entropion in 22% of the animals. There was a higher incidence of corneal pigmentary keratitis in Pugs (53%) and corneal fibrosis in Shih Tzus (36%).
