Eye doctors around the world frequently examine people for a chief complaint of floaters.
Patients describe a wide variety of symptoms, usually worsened by bright lighting conditions.
The vast majority of patients with eye floaters have a benign condition known as vitreous
syneresis in which portions of the normally clear and transparent vitreous jelly inside the eye
becomes less transparent. arely, eye floaters may be associated with significant ocular disease,
including vitreousbleedingor hemorrhage, retinal detachment, severe ocular injury, or diabetic
retinopathy. !nly a qualified eye doctor can determine whether or not the symptom of eye
floaters represents a serious ocular condition.
Para dokter mata di seluruh dunia sering mendapatkan pasiennya dengan keluhan utama berupa
floaters. Pasien menggambarkanfloaters dengan gejala yang bermacam " macam, biasanyamemburuk bila terpapar dengan cahaya yang terang.Floaters umumnya terjadi karena
pengendapan dari jaringan kolagen di badan vitreous dan merupakan proses degenerasi.
#ebagian besar pasien denganfloaters memiliki kondisi yang dikenal sebagai vitreous syneresis
atau kondisi badan vitreous mengerut secara alamiah dan sebagian dari cairannya terperas keluar. $ondisi ini mengakibatkan badan vitreous yang awalnya jernih menjadi keruh.Floaters
dapat disebabkan oleh hal lain walaupun hanya sebagian kecil, seperti perdarahan vitreous,
ablasio retina, trauma okuli, atau retinopati diabetikum.
#ometimes people see small, moving spots or specks in their field of vision. These sensations are
called floaters. %bout & out of '( people experience floaters at some point during their lives.#ometimes flashes of light, or flashes, are experienced with floaters. )loaters and flashes are
very common and are usually not a sign of a dangerous medical condition. *owever, if both
floaters and flashes begin suddenly, it may indicate a more serious eye problem, such as a retinal
tear or retinal detachment. This reference summary explains what floaters and flashes are, theirsymptoms, causes, and when they may indicate a more serious medical condition. The tutorial
also covers diagnosis, treatment, and self+care for floaters and flashes.
Pasien kadang " kadang sering mengeluhkanfloaters sebagai bintik " bintik atau titik yangbergerak yang mengambang di depan mata. )loaters, jika terjadi dalam waktu yang lama atau
meningkat secara perlahan, biasanya tidak berbahaya. ikafloaters terjadi secara tiba " tiba,
kondisi tersebut harus dicurigai berupa gejala dari ablasio retina.
The vitreous humor, or simply vitreous, is the clear, gel-like
substance that flls the cavity in the interior o the eyeball. It is
made up mainly o water and 1% fne, collagen fbers. In a normal,
healthy state, the vitreous has a sti, !elly-like te"ture and is
attached frmly to the retina. #ost o the causes o eye $oaters that
we know today begin with the degeneration o the vitreous. elow
is the top 1& list o what causes eye $oaters.

*umor vitreous adalah -at seperti gel yang mengisi rongga dalam bola mata. itreous sebagian
besar berisi air dan '/ jaringan ikat kolagen. 0ormalnya, vitreous kaku, memiliki tekstur seperti
gel yang melekat kuat pada retina. 1anyak kasus floaters merupakan proses degenerasi atau
sineresis vitreous.
2yodesopsia3also spelled as myiodeopsia, myiodesopsia, and myodeopsia4 is the medical termfor describing the perception of eye floaters. These are particles of various si-es and shapes that
occur the eye5s vitreous humor, the solution that maintains the eyeball5s shape. 6n medical
literature, eye floaters are sometimes referred to as muscae volitantes or mouches volantes.
Floaters disebut juga myodesopsia, dikenal juga sebagai myiodeopsia, myiosedopsia, atau
myodeopsia. Pada beberapa literatur, floaters disebut juga muscuae volitantes atau mouches
volantes.
Prevalensifloaters terjadi pada dewasa tua. $ondisi ini disebabkan karena bertambahnya umur,
humor vitreous mulai terjadi degenerasi bentuk dan mulai berkurang kejernihannya. 6ni
disebabkan karena akumulasi protein dan debris selular.
2yodesopsia is fairly common, and is more prevalent in older adults. This is because with
advancing age, the vitreous humor 3which is perfectly transparent during youth4, starts losing its
shape, fluidity and clarity. Proteins may aggregate together, and cellular debris may accumulate.
This gives rise to myodesopsia, and people describe their symptoms as dots, lines or specks of
dust in their field of vision. The perception of eye floaters is stronger when looking at bright
lights.
The causes of myodesopsia are many, but probably the most common is a natural change in the
consistency and shape of the vitreous humor that occurs with age. %s the consistency changes,
the proteins may precipitate out of solution, thereby becoming visible to the person. 6n addition,
as the vitreous humour loses it s shape, it may detach itself from the posterior part of the eye.
7uring detachment, impulses from the retina may cause the person to see flashes of light,
formally referred to as photopsia. The vitreous humour5s posterior detachment may also cause
part of the retina to be torn 3uncommon4, causing blood to leak into the vitreous and the person
will see a sudden appearance of dark dots. 2yodesopsia can also occur as a side effect of certainmedications 3such as drugs used to treat ocular herpes4 and as a complication of eye infections.
Penyebab floaters banyak, umumnya disebabkan karena proses perubahan konsistensi dan
bentuk dari humor vitreous yang disertai dengan bertambahnya umur. #eiring konsistensi
berubah, protein mengendap, sehingga gumpalan ini menjadi sesuatu yang mengambang di
depan mata sesuai yang dikeluhkan pasien. Tambahannya lagi, selama vitreous kehilangan

bentuknya, vitreous juga terlepas dari bagian posterior mata. #elama pelepasan, impuls dari
retina dapat menyebabkan seseorang melihat kilatan cahaya, yang dikenal sebagai photopsia.
Posterior vitreous detachment dapat juga menyebabkan retina terlepas, yang dapat menyebabkan
perdarahan ke dalam vitreous dan menyebabkan pandangan menjadi terhalang bintik gelap.
Floaters dapat juga terjadi akibat iatrogenic, seperti penggunaan obat herpes okuli san
komplikasi dari infeksi.
People who develop myodesopsia should consult with a doctor or an ophthalmologist. This is
mainly to ensure that the perception of eye floaters is not due to a serious underlying condition
such as a retinal tear 3which can lead to blindness if untreated4.
8nfortunately there is no medication that can treat eye floaters and the only medical option is
surgery. This can be of two types9 laser vitreolysis and vitrectomy. :aser vitreolysis uses an
ophthalmic laser 3known as a ;%< laser4 to break up each individual floater. *owever, this
procedure can be risky, is not always effective, and is performed only by a few specialists. !nthe other hand, vitrectomy involves draining off the vitreous humor 3and the floaters in it4 and
substituting it with a saline solution. This procedure is generally successful but complications
can occur. These include retinal detachment, cataracts, and optic nerve damage.
#ayangnya, sampai saat ini belum ada terapi medikasi dalam menangani floaters selain tindakan
bedah. %da dua tipe pembedahan9 laser vitreolisis dan vitrektomi. :aser vitreolisis menggunakan
laser ophtalmicum yang dikenal sebagai ;%< laser. 1agaimanapun juga, prosedur ini sangat
berisiko dan tidak selalu efektif. 7i sisi lain, vitrektomi melibatkan pengaliran humor vitreous
dan menggantinya dengan larutansaline. Prosedur ini biasanya berhasil, tetapi komplikasi dapat
terjadi, seperti ablasio retina, katarak, dan kerusakan nervus optikus.
