Fundus photography involves photographing the rear of an eye (also known as the fundus). The main structures that can be visualized on a fundus photo are the central and peripheral retina, optic disc and macula.

What is macular pucker and what are the symptoms

By Cristiano Antonino On Oct 6, 2022

Macular pucker, what is it? The eye, one of the most sophisticated organisms in the human body, relies on the delicate balance of all its parts

But this balance can break down due to external agents, pathologies or simply due to the advance of time.

One of the most frequent anatomical alterations is that of the vitreo-retinal interface caused by the passage of time: in these cases we speak of macular pucker, also called epiretinal membrane.

What is macular pucker

Macular pucker is the anatomical alteration of the border area between the vitreous body and the retina and consists of the development of a thin, translucent membrane over the macula, the central part of the retina.

When this membrane thickens, it tends to wrinkle (from the English pucker = pucker) and there is a progressive deformation and distortion of the retina, resulting in worsening of vision.

The main causes for which this pathology can develop are:

age: it mainly occurs after the age of 50;
previous eye infections;
previous laser treatment of the retina;
previous surgery;
retinal detachment;
consequences of ocular trauma.

Symptoms of macular pucker

The most common symptoms of pucker

blurred vision;
distortion of vision: the subject may perceive metamorphoses, e.g. when watching television or reading;
perception of objects of reduced size (micropsia) or of larger size (macropsia);
vision of wavy or broken lines instead of straight ones. For example, when reading, sentences may appear wavy;

Over time, symptoms may remain stable or gradually worsen.

However, there are no prevention procedures.

Diagnosis

The diagnosis can only be made by an ophthalmologist by means of a fundus examination, after dilation of the pupil.

During the examination, the specialist can also perform an Amsler test to assess the actual extent of line distortion using a special grid.

Diagnostic confirmation must be obtained by means of an OCT (optical coherence tomography) examination, which makes it possible to

analysing the layers of the retina, in particular the macula;
assess the extent of distortion of the retina itself;
determine the evolution of the pathology over time.

How macular pucker is treated

In most cases, macular pucker does not require treatment, even if it cannot regress, and this is the case when the symptoms are minimal and tolerable.

In other cases, however, the symptoms may be significant and disabling, causing reading and driving problems, or the OCT examination may indicate a trend towards progressive worsening of the pathology.

In these conditions, it becomes appropriate to consider surgery.
