Ophthalmologists are doctors who specialize in eye care. Regular checkups for eye health are crucial for healthy adults. They can detect vision changes and early signs of eye diseases. Early treatment can protect your vision. Your ophthalmologist can diagnose these conditions and offer treatment options. Here are some of the procedures available at an ophthalmologists clinic. Direct screening: This method of screening involves a patient meeting the ophthalmologist personally. During the visit, the patient will learn about eye care and general health. A personal relationship with the doctor can improve patient compliance. Direct screening is most beneficial to patients, as they get immediate feedback from the ophthalmologist. Pediatric ophthalmology: Paediatric ophthalmologists are the last 'generalists' in ophthalmology. They are trained to interact with children and conduct effective examinations in suboptimal circumstances. The growth of pediatric ophthalmologists has helped the field make huge advancements in the diagnosis and management of paediatric eye diseases. Diabetic eye disease: Screening for diabetes is one of the primary public health tools to prevent diabetic blindness. The World Health Organization and major ophthalmological societies recommend regular screenings for diabetic patients. The tests may be done by direct examination by an ophthalmologist or by fundus photography. A trained observer can detect the presence of retinopathy in the retina using a camera or a specialized computer software program. Automation is on the horizon, making this procedure even more convenient. A doctor's board certification in ophthalmology is required to practice in many health institutions. Graduates of residency programs will receive further training in subspecialties within the field. These programs may last from two to four years.
