Advantages:

The aim of the study was to evaluate visual function of the macula and changes in retinal layers in patients with retinal detachment following TPPV with Brilliant Peel assisted ILM peeling.

Methods:

The group consisted of 25 patients (12 male and 13 female) with retinal detachment, on whom ILM peeling was performed during TPPV. The mean age of the patients was 65.76. In all patients the macula was detached before the operation. In all patients, an ophthalmologic examination was carried out 6 months after the operation. It comprised functional parameters such as visual acuity for short and long distance, microperimetry, M-Charts test, fundus examination and OCT examination.

Effectiveness:

The mean duration of retinal detachment was 29,7 days. The mean visual acuity for the long distance before surgery was 0,11 after surgery was 0.27, while for the short distance was 1,04. M-Charts examination showed slight metamorphopsia, which means for the vertical dotty line 0,52 while for the horizontal 0,35. Mean MD in visual field for the macula was 7,19, while sLV amounts 3,53. Central retinal thickness after the operation in average was 289.22 ┬Ám. Mild oedema was present in 62,5% of patients. We did not observe occurrence of ERM in any patients. Abnormalities in RPE were present in 75% of patients.

Take home message:

We confirm that ILM peeling prevents secondary pucker. We can also confirm that ILM peeling restores the normal anatomy of the retina, which means less oedema and more normal central thickness. M-Charts tests showed metamorphosia. If we compared it with those which occurs in epiretinal membrane is less significant which means also better visual acuity for the long and short distance. Indicators of the visual field such as MD and also sLV were significantly elevated indicating damaged nerve fibers in the course of retinal detachment.
