Hereditary high myopia, frequent headaches and eye pain

Some myopia is not caused by reading books or watching TV before. Some myopia is high myopia, which is a genetic disease. It often causes patients to suffer from visual impairment, headaches, eye pain, and a sharp decline in vision. There will be dark shadows around the eyes and various complications.

Traction on the atrophic retina. Can cause retinal tears and detachment.

Symptoms

(1) Decreased vision.

(2) Myopia progresses rapidly: Unlike simple myopia, some people with high myopia continue to develop myopia even after adulthood, so it is also called progressive myopia.

(3) Protruding eyeballs: Severe myopia is mostly axial, with the eyeball becoming noticeably longer, the anterior chamber deeper, the ciliary muscle atrophied, and the eyeball of some people protruding outward.

(4) Poor dark adaptation function: The pigment epithelial cells of the retina become diseased, affecting the photochemical reaction process of the visual cells.

(5) Dark shadows in front of eyes: High myopia can cause vitreous degeneration, liquefaction, posterior vitreous detachment, etc.

Disease hazards

The harm of high myopia mainly lies in complications.

(1) Degeneration of vitreous, choroid and retina caused by abnormal eye structure and nutritional disorders.

(2) Macular degeneration, atrophy and posterior staphyloma caused by axial lengthening, scleral elongation and abnormal biomechanics.

(3) Amblyopia and strabismus caused by low visual acuity and dysfunction of accommodation and convergence.

Diagnosis

(1) Retinoscopy and ciliary muscle paralysis optometry.

(2) The intraocular pressure is measured by applanation tonometer. For eyes with high myopia, the value measured by the Schiotz tonometer is lower than the actual intraocular pressure.

(3) Use an indirect ophthalmoscope to examine the fundus with the pupil dilated to look for retinal tears and detachment.

(4) Use a slit lamp combined with a three-mirror or a 60D or 90D lens to examine the macular area and look for subchoroidal neovascularization.

(5) Fundus fluorescein angiography can be performed.

(6) Optical coherence tomography (OCT) can show macular detachment above the posterior staphyloma.
