Muscae volitantes
or Floater is defined as a condition of pathol moving black specks or
threads seen before the eyes, as results of opaque fragments floating in
the vitreous humour or a lens defect
due to degeneration of the vitreous humour. Floater as it suspends in
the vitreous humour, it tends to drift and follows the rapid motions of
the eye as a result of damage of the eye that causes material to enter
the vitreous humour.
VI. Treatments
A. In conventional medicine perspective
Treatment is not necessary, if the
diagnosis indicated that the floater is harmless and will do causes nay
damage to the eye vision, but in severe case, the following may be
recommended
1. Vitrectomy
In the study to to evaluate the role of pars plana vitrectomy
(PPV) in patients with persistent vitreous floaters (VF) in phakic
(56.7 %) or pseudophakic (43.3 %) eyes, Dr. Roth M, and the research
team at the Universitätsspital Bern, showed that PPV to be a safe and
effective primary treatment for visually disturbing
VF. In spite of the small number of cases with a lower PVA (5 eyes/16.7
%), which in the most severe case corresponded to a reduction of VA
from 1.0 to 0.6 due to a nuclear sclerosis of the lens, all patients
were satisfied. As vitreoretinal complications may occur, a critical
patient selection and a careful preoperative assessment of specific
risks of vitrectomy are mandatory(28).
2. Laser vitreolysis
Dr. Y M Delaney and the research team at
The Department of Ophthalmology Stoke Mandeville Hospital Aylesbury
Buckinghamshire, in the study of Nd:YAG vitreolysis and pars plana
vitrectomy: surgical treatment for vitreous floaters, indicated that
Patients’ symptoms from vitreous floaters are often underestimated
resulting in no intervention. This paper shows Nd:YAG vitreolysis to be a
safe but only moderately effective primary treatment conferring
clinical benefit in one third of patients. Pars plana vitrectomy, while
offering superior results, should be reserved for patients who remain
markedly symptomatic following vitreolysis, until future studies further
clarify its role in the treatment of patients with floaters and
posterior vitreous detachment(29).
