Controlled draining in treatment of serous retinal detachment caused by optic nerve pit
Malov I. A., Takhchidi K. P.

Since 1994 we use laser retinopuncture for treatment of cystic maculopathy,
serous retinal detachment and macular hemorrhages. Aim of the study is
to develop controlled draining on the basis of laser retinopuncture employing
natural intravitreal circulation in combination with retinal lasercoagulation.
Patients and methods: 5 eyes of 5 patients aged from 18 to 40 years
with serous macular detachment caused by optic nerve pit were treated.
Mean visual acuity was 0.05. Three eyes underwent controlled draining
of subretinal cavity: after puncture of the inner wall of subretinal cavity
with YAG-laser (1064 nm; E=7.1 mJ, n = 1-2) tunnel lasercoagulation of
retina was performed. Its aim was to direct the flow of subretinal fluid
into the vitreous, bypassing the macula.
Results: In 3 patients after controlled draining the macula was
attached and visual acuity improved up to 0.15-0.2. In 2 cases after barreer
lasercoagulation alone retina remained detached and visual functions did
not improve.
Conclusions: Control of draining process after laser retinopuncture
for serous macular detachment is possible. Further investigations in this
area are necessary.
