Internal And External Ocular Health
External ocular health is checked and monitored using a slit lamp microscope. The slit lamp is an illuminated microscope which allows a detailed, binocular and magnified view of the outer surface of your eye. The optometrist will inspect the eyelids, eyelashes, conjunctiva, episclera, sclera (white of the eye), cornea, anterior chamber, iris and crystalline lens looking for abnormalities or disease. If problems are detected they can be documented using anterior eye imaging, allowing detailed photographs or videos to be stored.
Internal ocular health can be checked using a hand held microscope known as a direct ophthalmoscope. More commonly a technique known as indirect ophthalmoscopy is used which involves the use of the slit lamp microscope in conjunction with a condensing lens held in the hand of the optometrist and placed a few millimetres from your eye. This allows very detailed, binocular and magnified views of the back of the eye. The optometrist will inspect the optic nerve, macula, blood vessels etc looking for problems such as glaucoma and macular degeneration.
Both procedures are relatively quick and completely painless. Internal ocular health checks may involve the use of an eye drop known as a mydriatic which is used to dilate your pupils. Dilated pupils offer a clearer, wider view of the back of the eye which may be necessary if you have small pupils or conditions such as diabetes meaning a detailed view of the eye is advisable.Back Next
