What is cornea Guttata?
The cornea guttata is an ocular condition characterised by the appearance of droplet shaped bulges in this part of the eye. As they affect the corne, which is the main refractive element of the eye that allows clear vision of objects, they can cause vision loss or impaired vision.
How do you treat a corneal Guttata?
The symptoms can be treated with an anti-oedema ointment or eyedrops, but when the disease has advanced, the solution is a posterior lamellar transplant in which a healthy donor endothelium is transplanted (DMEK or DSAEK).
Which investigation will be most useful in a patient of Fuchs endothelial dystrophy?
The diagnosis of Fuchs’ endothelial dystrophy is clinical; however, there are some diagnostic tests that can be helpful. Pachymetry, or measurement of the central corneal thickness, is helpful in following a patient with Fuchs’ dystrophy. Over time you will see increasing corneal thickness as the disease worsens.
How do you grade a Guttata?
Cornea guttata were divided into 5 grades (Fig 1) according to the area of dark spots, as seen on specular microscopy, in the central part of the cornea, as follows: grade 1 (0% but evident by slit-lamp examination), grade 2 (less than 10%), grade 3 (10%–25%), grade 4 (25%–50%), and grade 5 (more than 50%).
Should cataract surgery be performed on someone with Fuchs disease?
Any intraocular surgery such as cataract surgery will further reduce the number of endothelial corneal cells in a patient with Fuchs’ dystrophy. If the Fuchs’ dystrophy is still in its early stages and there is sufficient endothelial cell reserve, the patient can proceed with cataract surgery alone.
What is bullous keratopathy of the eye?
Bullous keratopathy is an eye disorder that involves a blister-like swelling of the cornea (the clear layer in front of the iris and pupil). Symptoms include sensitivity to bright light, blurred vision, and intermittent feeling of a foreign object in the eye.
What is Fuchs corneal dystrophy?
In Fuchs’ (fewks) dystrophy, fluid builds up in the clear layer (cornea) on the front of your eye, causing your cornea to swell and thicken. This can lead to glare, blurred or cloudy vision, and eye discomfort. Fuchs’ dystrophy usually affects both eyes and can cause your vision to gradually worsen over years.
How do you treat a cornea Bullae?
Bullous keratopathy is treated by an ophthalmologist (a medical doctor who specializes in the evaluation and treatment—surgical and nonsurgical—of eye disorders). Salty eye drops (hypertonic saline) and salty ointments (hypertonic sodium chloride) are used to draw the excess fluid from the cornea.
