视乳头杯盘比(C/D)扩大,多为长期慢性眼压增高所致,有发展为青光眼的趋势。我们认为凡视乳头C/D扩大超过0.5者发展为青光眼的可能性较大(见《航空军医资料》1980年第2期)。据此我们曾在20期学员中停飞6人,当时这些学员除了视乳头C/D扩大外并无其它症状。在此后的3～10年,其中2人已发展为慢性单纯性青光眼。 例1,男,29岁,学员,现在内蒙某部做技术工作。1981年转校体检时发现双侧视乳头C/D扩大,右0.5,左0.6,视力右1.5,左1.2,角膜瞳孔未见异常,测眼压,右2.5 kPa(18.86 mmHg),左2,74 kPa(20.55mmHg),做青光眼激发试验,右眼阴性,左眼阳性,作停飞处理。3年后因有头痛、眼胀、恶心等症状到医院检查,怀疑有青光眼症状,来信索取既往病历。自述视力 Optic cup cup than (C / D) to expand, mostly due to chronic high intraocular pressure due to the development of glaucoma. We consider it more likely to develop glaucoma where visual papillary C / D enlargement exceeds 0.5 (see Air Force Medical Information, No. 2, 1980). Based on this, we stopped at 6 students during the 20 sessions of the program. At that time, these students showed no symptoms other than expanding the optic nerve C / D. In the next 3 to 10 years, 2 of whom have developed chronic uncomplicated glaucoma. Example 1, male, 29 years old, trainee, now a ministry in Inner Mongolia to do technical work. In 1981 the school examination revealed bilateral bilateral papilla C / D expansion, right 0.5, left 0.6, visual acuity 1.5, left 1.2, no abnormal pupil, measured intraocular pressure, right 2.5 kPa (18.86 mmHg), left 2, 74 kPa (20.55mmHg), do glaucoma challenge test, the right eye is negative, the left eye is positive, to stop flying treatment. 3 years later due to headache, swollen eyes, nausea and other symptoms to the hospital for examination, suspected symptoms of glaucoma, letters from the past medical record.
