Abstract Details

Purpose:

We use various technologies of RLC for ROP treatment: the forehead ophthalmoscope, slit lamp, using a pattern and impulse technology. We have analyzed the effectiveness of various technologies of RLC for treatment of threshold stages of ROP. Criteria of effectiveness: regression of the disease, absence of retinal detachment after 3 months.

Setting:

State Institution Eye Microsurgery Complex named after academician S.N. Fyodorov, Khabarovsk, Russia

Methods:

85 children (162 eyes), gestational age: 26-32 weeks (average 28±1.6); mass at birth: 587-1701 grams (average 849±147.8 grams). At the moment of treatment: age 32-36 weeks (average 34±1.3); body weight: 1078-2450 grams (average 1883.8±478.1 grams). In 33 eyes – AP-ROP, in 129 eyes – ROP III “+” illness. Groups were formed: 1st – 10 children (17 eyes): RLC was carried out with the forehead ophthalmoscope (Iridex Oculight Slx, 810 nm), 2nd – 30 children (60 eyes): lazer VisuLas 532 “Carl Zeiss”, 3rd - 45 children (85 eyes): using a pattern of VALON. Operations were carried out under a mask anesthesia.

Results:

In 1st group duration of operation – 30-48 min. (average 36±4.2) in one eye, in 2nd – 18-31 min (average 24±4.1), in 3rd – 11-25 min (average 17±5.3). Effectiveness of treatment of ROP III “+” illness in 2nd and 3rd groups has no statistically significant difference, but significantly higher than in 1st group (85% – 2nd group, 90% - 3rd group, 77.5% - 1st group). In AP-ROP efficiency is significantly higher when using pattern RLC – 61.5% vs. 42% at pulse RLC, and only 12.5% - using forehead ophthalmoscope. Effectiveness of RLC in 3 months: 1st group – 47% of the eyes, 2nd – 76.5%, 3rd – 90.5%.

Conclusions:

1. Pattern technology reduces operation time 2 times (average 17±5.3 min versus 36±4.2 min when using the forehead ophthalmoscope). 2. After 3 months frequency of regression of threshold ROP is maximum when using pattern RLC – 90.5%, while using pulsed RLC – 76.5%, using the forehead ophthalmoscope – 47% . 3. Pattern RLC enables to improve the effectiveness of AP-ROP treatment from 42% to 61.5%.
