Eye Conditions and Treatments

Retina Diseases and Treatment

By covering the internal part of the eye, the retina is the layer which communicates with the brain (the network layer) by signalling the vision through the optic nerve. The vitreous, which fills the inside of the eye is of a gel consistency and with ageing or as a result of some eye diseases, it loses the properties of vitreous tissue and starts to liquefy. As a result, the retina separates from its points of attachment. Most of the time, no problems develop during this process, but occasionally during this separation, one or more areas of the retina may be torn. The liquefied vitreous passing from these torn areas may separate from the retinal layer and the disease known as retinal detachment develops. Vision is permanently severely affected and thus this disease must be treated promptly.Figure 1. Argon laser photocoagulation treatment.The most significant cause is ageing. In addition, other risk factors are known to be having undergone cataract surgery, application of YAG laser capsulotomy…

Macular Edema

DEFINITION: The macular edema center is one of the most common causes of loss of vision. In the macula, liquid is accumulated in the retina. Edema takes the form of intra-retinal cysts, and this is called cystoid macular edema. When edema develops, the central vision of the patient is disrupted.RISK FACTORS AND CAUSES: It may be related to cataract surgery, macular degeneration due to aging, uveitis, diabetes, retinal embolism, or medication toxicity. Following cataract surgey, cystoid macular edema, with a possibility of 1-3%, emerges occurs 2-4 months within 1 year.Figure 1. Macular optical coherence tomography image of a healthy eye.FINDINGS: It is characterized by blurred vision and reduced central vision. However, since this clinical picture is not unique to any specific disease, the ophthalmologist should carry out an examination in detail for diagnosis.DIAGNOSTIC TESTS: Diagnosis can be made through eye examination.  The most common diagnosis method is to examine the bottom…

Glaucoma

DEFINITION: Disruption to the internal eye fluid or increased resistance to the external flow results in internal pressure more than the eye can tolerate and thereby a group of diseases characterised by irreversible damage to the optic nerve.Figure 1. Appearance of the normal optic disc (left) and glaucomatous optic disc (right).SYMPTOMS AND FINDINGS: In open angle type glaucoma, the disease gives no indications until the advanced stage at which vision loss develops. The progressive course of the disease is generally slow and initially the patient is not aware of impairments in the field of vision.In acute closed angle type glaucoma the prevention of internal eye fluid circulation results in high levels of internal eye pressure. In these cases, clouded vision, coloured circles around light, severe pain in and around the eye, redness of the eye and nausea and vomiting may be seen. In congenital glaucoma cases, there are findings of watering of the eyes, large diameter cornea and loss of…

Macular Hole

DEFINITION: This hole develops in the center of the macula which enables the central vision. It has four phases. It mostly emerges by the detachment of the vitreus from the macula due to aging. It occurs in 3 cases out of 1000. Once one of the eyes is affected, the risk of development in the other eye within 5 years is 10%.Figure 1. Preoperative (left) and postoperative (right) Multicolor optical coherence tomography images of a patient operated for full thickness macular hole at our hospital.RISK FACTORS: It mostly affects individuals who have no eye diseases and who are over 50 years of age. It is more common in women. It may also develop due to high myopia, trauma, intraocular inflammation, retinal detachment and other eye diseases.FINDINGS: The disease starts with distorted and blurred vision in the center of vision. With the expansion of the hole over weeks and months, central vision is seriously affected.Figure 2. Preoperative (left) and postoperative (right) B scan optical coherence…

Cataract

DEFINITION: Cataract is the blurring of the eye lens after losing its transparency.Figure 1. Demonstration of a healthy eye (left), an eye with cataract (middle) and steps of phacoemulsification surgery (right)CAUSES AND RISK FACTORS: The most common type of this disease is that which is due to aging. There are also other types accompanying systemic diseases like diabetes, myotonic dystrophia, atopic dermatitis, and neurofibromatosis-2. Secondary cataracts can be seen in eye diseases: chronic uveitis, acute angle closure glaucoma, high myopia, and hereditary fundus dystrophia. Secondary cataracts can also be found in eye traumas due to some systemic medications. There are genetic cataracts and congenital cataracts. In such cases, underlying systemic diseases should be investigated.Figure 2.
