Direct ophthalmoscopy involves using a handheld device known as an ophthalmoscope. This method allows for the examination of the retina with a magnification of approximately 15 times. The ophthalmoscope has a light source and a series of lenses that help focus on different parts of the retina.
Advantages of Direct Ophthalmoscopy - High Magnification: Enables detailed observation of the central retina. - Portability: The device is compact and can be used bedside. - Ease of Use: Relatively straightforward to learn and perform.
Disadvantages of Direct Ophthalmoscopy - Limited Field of View: Typically offers a narrow view of the retina. - Skill-Dependent: Requires significant skill and experience to interpret findings accurately. - Poor Peripheral Visualization: Peripheral retinal disorders might be missed.
