Also referred to as photopsia, you may experience flashing lights and see luminous floaters in the vision of one eye or both eyes. Photopsia may also appear to you as:

  • flickering or shimmering lights
  • small floating objects and shapes
  • moving or static spots

Photopsia is usually a symptom of an underlying condition.

The main concern with photopsia is the need to exclude any retinal traction that may lead to a retinal tear and/or detachment (which, if left untreated, may lead to severe visual impairment).

Other less common causes include end-stage photo-receptor degeneration (age-related macular degeneration), but you should consult your attending physician for a detailed assessment.

Can I do TransPRK if I have dry eyes due to Meibomian Gland Dysfunction?

Yes you are right that meibomian gland disease (MGD) is a major cause of dry eyes. If you do have a combination of MGD and dry eyes, there are many ways to treat them! However, since you mentioned that your eyes are neither dry nor painful without contact lens use, I suspect you may have another condition known as Giant Papillary Conjunctivitis (GPC). It is very common for chronic contact lens over-wearers to develop GPC. It is your body’s response or ‘rejection’ to the chronic use of contact lenses, which is regarded as a ‘foreign’ material to your eye.

Does a low dosage isotretinoin course which falls below the recommended total cumulative dosage increase the chance of a relapse?

There is a cumulative therapeutic dose in the range of 120mg – 140mg/kg that some doctors adhere to in the bid to reduce the relapse of acne. Sometimes, doctors may prescribe lower doses (with lower side effects) until the acne has cleared and continue the course for a few more months after. It really depends on the prescribing doctor as each has his/her own protocol. If you find that you are still having relapses with lower doses then discuss with your doctor the option of a course to achieve the therapeutic accumulative dose.
