surgical treatment and optical coherence tomographic evaluation for accidental laser-induced full-thickness macular holes - handheld laser distance measuring device

Purpose report October-
Thickness of retina (MHs)
Accident caused by laser equipment
Patient and method this retrospective case series includes 11 eyes in 11 laser patients
Treatment-induced MHs by intra-boundary membrane resection (ILM)
Stripping, filling with gas or silicone oil.
Evaluation includes complete eye examination, retina spectroscopy-
Domain optical coherent tomography (SD-OCT)
And fundus photography.
The main observation indicators were MH closed degree and vision;
The secondary result is to evaluate changes in the retinal pigment epithelial and photosensitive layers after sequenceoperative SD-OCT images.
Results: five patients were accidentally injured, including one patient. YAG)
Handheld laser and 6 patients.
The diameter of MH varies from 272 to 815 μm (mean, 505. 5±163. 0u2009μm)preoperatively. Best-
Corrected vision (BCVA)
Increase from average 0. 90 logMAR (
Range, counting fingers-8/20)
The mean value before operation is 0. 34 logMAR (
Range, one count finger-20/20)
After surgery (P=0. 001, t=4. 521).
7 out of 11 patients (63. 6%)
Got a better BCVA than 10/20.
The center depression was high reflection in 10 patients, and the center depression before operation in 4 patients had a focal clubbing depression.
In the final follow-up
Up, all 11 eyes showed the following: closed retina holes, varying degrees of damage to the external membrane (ELM)
And the ellipse and Junction Band of the external photosensitive body.
In 10 eyes, the form of destruction is a focal defect outside the retina.
After the operation, high reflection and focal vein depression in the central depression still exist.
Accidental laserinduced full-
The thickness of the retina can be successfully closed through surgery.
In recent years, the frequency of unintentional retinal damage caused by laser equipment, especially hand-held laser damage, has become higher and higher.
However, there is little data on these types of injuries, mainly in the form of case reports.
We are here to report 11 eyes of 11 laser patients.
Retina holes treated by glass cutting.
After surgery, all the retina holes were closed and the corresponding vision was significantly improved.
