Ocular Examination:

Right eye:V OD:0.6, IOP:17 mmHg

The right eye was normal.

Left eye:VOS HM/BE.,IOP> 60mmHg

The lid was swollen, conjunctival congestion, chemosis, corneal edema. The anterior chamber was shallow, with 2CT in the center，1/3CT periphery. The pupil was moderately dilated,light reflex was slow, lens density was increased, vitreous was bloody opacities, the rest was unclear.(Figure 1-2)

辅助检查

2010年12月13日B超检查：左眼玻璃体弥漫点状低回声，团状、膜状中强回声后连视盘及球壁。提示左眼玻璃体积血，脉络膜下腔积血？（图3）

Ancillary examination

三、查房记录

Consultation

杨瑾副主任：

根据病史及眼部检查，考虑患者诊断为继发性青光眼，但患者否认青光眼家族史，外伤史，全身病史。发生继发性青光眼有多种考虑，首先，血象异常是否是造成眼科疾病的病因，需要进一步完善相关血液科检查，如出凝血功能检测等。第二，虽然患者主诉否认外伤史，但仍要高度怀疑考虑钝挫伤造成继发青光眼的可能性，第三，患者为老年男性，考虑是否为年龄相关性黄斑变性——湿性AMD造成的新生血管突然破裂出血。

Dr.Yang Jin：

According to the medical history and the eye examination, patient with secondary glaucoma was considered to be diagnosed. However, the patient denied glaucoma family history, trauma history and other past history. There were many considerations of secondary glauma: firstly, the abnormal hemogram should be ruled out the possibility of haematology, other haematology examination, such as blood clotting function was needed to completed. Secondly, tramatic secondary glaucoma must be suspected, although the patient denied trauma history. Thirdly, in consideration of an old male patient, AMD causing neovessels sudden rupture and hemorrhage should be carefully ruled out.

四、病例相关知识

Relative knowledge

外伤性青光眼

眼球钝挫伤致前房积血可继发早期眼内压升高。血液可阻塞小梁网，也可因外伤后小梁水肿所致。治疗首选药物，若眼压持续升高可手术介入，尤其当再次发生出血时。顿挫伤晚期的眼内压与直接房角损害有关。外伤与青光眼之间的关系尚不明确。临床检查可见前房加深，房角镜检见房角后退。药物治疗通常有效，必要时行引流手术。眼前节的破裂或顿挫性撕裂常伴随前房消失。虹膜疝入伤口可自发形成前房，或通过手术形成前房。如果伤后前房不能形成，必将形成虹膜前粘连而导致不可逆的房角关闭。

Glaucoma secondary to trauma

Contusion injuries of the globe may be associated with an early rise in intraocular pressure due to bleeding into the anterior chamber (hyphema). Free blood blocks the trabecular meshwork, which is also rendered edematous by the injury. Treatment is initially medical, but surgery may be required if the pressure remains elevated, which is particularly likely if there is a second episode of bleeding. Late effects of contusion injuries on intraocular pressure are due to direct angle damage. The interval between the injury and the development of glaucoma may obscure the association. Clinically, the anterior chamber is seen to be deeper than in the fellow eye, and gonioscopy shows recession of the angle. Mecical therapy is usually effective, but drainage surgery may be required. Laceration of contusional rupture of the anterior segment is associated with loss of the anterior chamber. If the chamber is not reformed soon after the injury either spontaneously, by ires incarceration into the wound, or surgically peripheral anterior synechiae will form and result in irreversible angle closure.

年龄相关性黄斑变性

年龄相关性黄斑变性是老年人永久性致盲的首要原因。本病临床和病理表现差异较大，可分为两种类型：非渗出型（干性）和渗出型（湿性）。虽然AMD的病人通常只呈现非渗出性的改变，但患者常因此病造成严重视力丧失，主要原因是视网膜下新生血管的形成以及相关的渗出性黄斑病变。从脉络膜长至视网膜下的新生血管是诱发玻璃膜疣发展为黄斑脱离和不可逆性中心视力丧失的最重要的原因。湿性AMD造成的新生血管突然破裂出血可导致视力突然丧失。

Age-related macular degeneration

Age-related macular degeneration is the leading cause of permanent blindness in the elderly. The disease includes a broad spectrum of clinical and pathologic findings that can be classified into two groups: nonexudative (dry) and exudative (wet).Although patients with age-related macular degeneration usually manifest nonexudative changes only, the majority of patients who experience severe vision loss from this disease do so from the development of subretinal neovascularization and related exudative maculopathy. Ingrowth of new vessels from the choroid into the subretinal space is the most important change that presisposes patient with drusen to macular detachment an irreversible loss of central vision. Neovessels sudden rupture and hemorrhage in wet AMD could cause a sudden loss of visual acuity.
