About this trial

To investigate the efficacy and safety of modified deep lateral wall decompression and/or medial wall decompression for Moderate-to-severe Grave's Ophthalmopathy.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

EUGOGO/NOSPECS grade was moderate-to-severe thyroid associate ophthalmopathy;

CAS≤3 score;

stable thyroid function for at least 6 months;

able and willing to participate in clinical trials and ensure regular follow-up;

Disqualifiers

any uncontrollable clinical problems (severe mental, neurological, cardiovascular, respiratory and other systemic diseases and malignant tumors);

B-ultrasound or CT, MRI found other diseases causing exophthalmos (intraorbital space occupying lesion, inflammatory pseudotumor, neurofibroma, etc.);

uveitis, glaucoma, high myopia, diabetic retinopathy and other eye diseases

those who were considered by the researchers to be excluded

Trial design

Design model

Single group

Treatments tested in this trial

  • modified deep lateral and/or medial wall decompression

    Procedure/Surgery

    Modified deep lateral orbital wall decompression is based on traditional outer wall decompression with combined abrasion of the deep outer orbital wall (including the greater pterygoid wing) to achieve adequate enlargement of the orbital cavity.

Trial outcomes

Primary outcomes

1

best corrected visual acuity (BCVA)

Using Snellen scale, decimal fraction

Time frame
within 24 weeks of surgery

Secondary outcomes

1

value of Hertel

as measured using a Hertel exophthalmometer, to describe the degree of exophthalmos

Time frame
within 24 weeks of surgery
2

the mean deviation value of visual field (VF)

The mean deviation (MD) gives an overall value of the total amount of visual field loss, with normal values typically within 0dB to -2dB. The mean deviation value of visual field (VF) was examined by HFA (Humphrey II, Carl-Zeiss, Dublin, CA).

Time frame
24 weeks after surgery
3

pattern standard deviation value of visual field

The pattern standard deviation (PSD) can filter out the decrease in visual acuity caused by turbidity of the dioptric interstitial. The pattern standard deviation (PSD) was examined by HFA (Humphrey II, Carl-Zeiss, Dublin, CA).

Time frame
within 24 weeks of surgery
4

the P100 latency of pattern visual evoked potential (PVEP)

The visual stimulus was a pattern reversal checkerboard displayed on a black and white monitor placed 105 cm from the patient. The wave latency of P100 was recorded.

Time frame
within 24 weeks of surgery
