Should I protect my eyes from sun exposure while taking antibiotics?
Some antibiotics make your skin, including the skin of your eyelids, more susceptible to sunburn than it usually is. Damage to the lens and perhaps even the retina of your eye can occur with long-term, repeated, unprotected exposure of the eyes to bright sunlight; but this is not made worse by taking antibiotics. No extra protection of your eyes beyond the usual use of ultraviolet-absorbing sunglasses is necessary when you are taking antibiotics.
How can uveal coloboma be inherited?
Honor Society of Nursing (STTI) answered
Isolated coloboma can follow all possible patterns of single-gene inheritance, namely autosomal dominant, autosomal recessive, and X-linked. In one family, however, coloboma will follow only one pattern. For instance, in case of an autosomal dominant pattern, a person with coloboma would have a 50/50 chance of passing on the coloboma to each of his or her offspring. In families with a single case of coloboma, it is not possible to identify the pattern of inheritance involved; therefore, it is not possible to give an exact recurrence risk number. The recurrence risk of coloboma computed from averaging data across many families (empiric risk) is about 10 percent. This is an imperfect number because it mixes information from families where this risk may be close to 0 percent with information from families where the actual risk may be 25 percent or even 50 percent.
The topic of inheritance of coloboma is complicated by several factors:Sometimes, a person who is at risk for developing coloboma may not develop the condition, or it may be so minor that it goes unnoticed. This may appear in the family history as an inconsistent, noninterpretable pattern of inheritance.Knowing the pattern of inheritance of coloboma in a family does not give information on how severely an at-risk person will be affected (for example, how good their visual acuity will be).There may be more than one gene involved in being at risk for coloboma, which makes predicting inheritance even more difficult.
For coloboma due to a known syndrome, such as CHARGE syndrome, inheritance is based on what is known about that particular syndrome. However, it is rarely, if ever, possible to say whether coloboma will be a feature of the syndrome in a person inheriting the genetic background responsible for this syndrome.
The answer is based on source information from the National Institute of Diabetes and Digestive and Kidney Diseases.
How often can I safely use artificial tears?
Artificial tears are drops that you can safely use in your eyes as often as you need them, and they will not harm the eyes. If you are using them frequently, you may wish to get "preservative-free" tears, as sometimes the preservatives can be irritating for some people. Also, if you are finding you need the artificial tears often, it may be a good idea to speak with your eye doctor, in case there is an underlying dry eye condition that needs further treatment.
