Understanding Macular Holes
A macular hole is a defect that develops at the central fixation point of the eye (macula). As it affects the most vital area used for central fixation, symptoms can impact on daily life very significantly.
A macular hole is seen in the photography and this is confirmed to be a full-thickness macular hole on OCT scanning. A full thickness hole should be repaired early for the best success rate.
Causes
Less common causes are macular holes due to severe myopia or severe eye trauma. Looking at an eclipse without protection is an uncommon reason for macular hole formation!
Symptoms
Using an Amsler chart or straight edges of everyday objects (e.g. edges of doors and windows) to test oneself for distortion can help to identify potential macular hole symptoms.
Macular Hole Treatment
Vitrectomy Surgery: This is currently the only proven method of closing a macular hole. Macular hole closure success rates are very much dependant on the duration of the hole. Macular holes treated within 6 months of development have the highest closure success rates. Therefore it is important to diagnose and treat macular holes early.
FAQs about Macular Hole
Studies have shown that if one eye develops a macular hole, the other eye is at significant risk of also developing a macular hole.
For this reason, a macular hole should be repaired early to increase the success rate and secure vision in 1 eye in case the other also develops a macular hole.
Since the “good eye” of an individual with a macular hole is also at risk, it should be monitored regularly to pick up a macular hole early.
