Ambati 1 Introduction The eye is the organ that allows for vision, the ability to see the world. For a person to be able to see, light must enter through the transparent cornea in the front of the eye, be focused by the lens, and detected by the light-sensitive retina in the back of the interior of the eye. In humans, photore- ceptors can be divided into two primary cell types: rods and cones. Rod photorecep- tors, which greatly outnumber cone photoreceptors, are incredibly sensitive to light and are primarily responsible for vision in dim light conditions. Cone photorecep- tors, on the other hand, operate primarily under bright light conditions and are responsible for providing color-rich and detailed vision. Rods and cones are not evenly distributed throughout the eye; rods are found throughout the entire eye, with the exception of the very center of the retina. In humans, cone photoreceptors are predominantly found in a structure called the macula, which is located in the center of the retina and where light is most focused from the lens. For healthy vision, each component of this pathway must work in concert, and degeneration or injury to any one of these anatomical structures can lead to visual impairment or blindness. At these early stages of the disease, patients com- monly have no reported visual deciencies. After age, smoking is widely considered to be the next strongest risk factor for developing the disease. Individuals who have smoked at one point or who currently smoke are more likely to develop the disease and to have advanced forms of the disease as compared to individuals who never smoked . The number of affected individuals is expected to rise as the aging also comprise the fastest growing segment of the gen- eral population. Evidence for both pro- and anti-angiogenic roles of macrophages abound in the literature. Macrophage depletion by genetic ablation of the chemoattractant Ccl2 or Ccr2, necessary for macrophage recruitment to the retina, has been shown to promote angiogenesis in mouse models . Macrophages can interchangeably adopt either one of two polarization states, M1 or M2, which determine their activity in tissue. M1 macrophages are typically understood to assume pro-inammatory roles in tissue, while M2 macrophages are involved in wound repair activities . These pro-inammatory mediators are thus attractive targets for future therapeutic approaches. Inammasome activity is the result of two distinct phases: the rst step is priming, in which inammasome-associated gene products (e. The classical pathway requires antibody binding to antigen for activation by the C1 protein complex , and this same set of complement proteins (C2, C4, etc.
It is important that the locally written guidelines are based on national and regional guidelines 100 mg silagra amex. They are to be interpreted with a degree of flexibility dependent on the risk of infection purchase silagra 50mg amex, as well as an assessment of the physical and emotional state of the patient. A pragmatic and compassionate approach is needed for a patient who may be trying to regain control after the assault. The benefit to the patient of any investigation needs to be weighed against the risk of exacerbating or prolonging the patient s distress. The purpose of a forensic examination is to obtain evidence for legal proceedings. Having a forensic examination does not commit the person to legal proceedings as a statement can always be withdrawn at a later date if the patient wishes. If the patient wishes to report to the police, do not perform any examination or the forensic examination may be compromised. If the person who has been assaulted attends soon after the assault and is going to have a forensic examination, then it is best if they do not pass urine or have their bowels open. If they do then it is important to save the toilet tissue as it may have forensic use. In some larger cities there are specific sexual assault centres where people may self refer for a forensic exam and support without having to be seen by the police. Patients who do not want a forensic exam may still wish to report the crime to the police. It is important that the police are aware of assaults particularly where there may be a serial rapist where reporting could identify the assailant in the police investigation. It is good practice to create links with local police stations to facilitate referral and support for the patient; this would include links with chaperones and victim support organisations. Unless requested by a court of law the clinic notes remain confidential and are not disclosed to any third party. The difference between forensic and therapeutic examination needs to be explained to the patient. The patient may attend alone or be accompanied by a police officer or a representative from Victim Support. A police officer is obliged to disclose any new information learned regarding the case to his/ her superiors and to the defence team so it is good practice to inform the patient of this. Criminal injuries compensation Women and men who have been sexually assaulted can apply for compensation from the Criminal Injuries Compensation Authority. To be eligible for compensation, they must have reported the incident to the police. If patients want the clinic to write a letter in support of their claim for compensation, they need to give written permission in their clinical notes. It is recommended the patient is offered a choice in the gender of healthcare workers they see, wherever possible. All referrals of patients aged under 16 or over 60 years need to be discussed with a consultant prior to booking an appointment. If a sexually active 14 to 16 year old person walks in to the clinic and discloses sexual assault, it may be appropriate for them to be seen in 178 the sexual health clinic. It is essential that such cases are discussed with a consultant and advice sought from the paediatrician / child protection team. For patients under 16 it is essential to assess and document the Fraser guidance/ competence, as for all under 16-year olds. This will not be possible if the patient discloses assault when in the clinical room with the doctor, and the course of the consultation is dependant on the experience of the health adviser/ nurse/ doctor available. When the patient arrives in the department, they may be given the option of waiting in a private room, for example a consulting room, health adviser room but not the main clinic waiting room. They are ideally greeted as soon as possible by a nurse, health adviser or doctor, who will briefly explain the clinic process. Waiting during the process of consultation needs to be minimised, so a fast track system is recommended. It is recommended that the health adviser takes a brief history in order to make an assessment regarding relevance of: Whether the person wishes or needs police input or forensic screening. Place on recall system and document in notes re recall Offer the patient details of support agencies for example Victim Support, Rape Crisis Centre, and Survivors. Offer an information sheet with phone numbers of support groups (see appendix 1) Discuss any other concerns s/he might have. Psychological trauma and 180 distress can be common following sexual assault, and early intervention may reduce long-term psychological damage. It is good practice that the health adviser carries out a counselling assessment, and where appropriate offer short-term supportive counselling or refer to the relevant local support services. It is recommended that the health adviser also assesses the need for acute psychiatric intervention. Early referral to a clinical psychologist is recommended if the patient does not appear to be coping with the aftermath of the assault.
