To determine the correlation between the size of the macular hole obtained by Optical Coherence Tomography (OCT) and digital photography using the VISUPAC software.
Materials and Methods: :
15 patients undergoing macular hole surgery in the period between September 2003 and 2004 were recruited retrospectively. The sizes of the macular holes were measured on the digital photos using the visupac software. This was repeated on the optical coherence tomography images. The findings were compared.
Fifteen patients (4 males and 11 females) with an average age of 67 years were recruited. The digital images of macular holes were analysed using the VISUPAC software. The greatest linear diameter and the diameter of the inner circle of the macular holes were measured. The results were compared with the measured minimum horizontal diameter and the base diameter of the holes on the OCT images, using callipers.
The greatest linear diameter ranged between 474 and 1010µ (mean 715µ) on OCT versus 450 and 1030µ (mean727µ) on digital photography using the VISUPAC software. The photographic measurement of the inner circle corresponding to the OCT minimum diameter, ranged between 220–680 µ (mean 400µ) on OCT compared to 224 – 640µ ( mean 384µ) using VISUPAC software.
The dimensions of the macular holes on software based digital photography correlated well with the OCT findings. The use of this method could be a useful alternative way to assess the size of the macular hole. This could prove to be useful in predicting the surgical success.
