Celal Bayar Üniversitesi Tıp Fakültesi Göz Hastalıkları Anabilim Dalı-MANİSA
Asteroid hyalosis (AH) is a usually asymptomatic and unilateral degenerative condition in which bodies consisting of calcium and phospholipid are suspended in the vitreous fibrils. The aim of this study is to detect the prevalance and the coexisting ocular and systemic pathologies associated with AH and to emphasise its demographic properties. Visual acuity, refraction and fundus examination characteristics were noted of patients in whom AH was diagnosed in our clinic. Patients' blood glucose, total cholestrole, uric acid, calcium and phosphorus values were compared with an age matched control group. AH was diagnosed in 22 eyes of 16 patients aged 60.23±12.0. AH prevalance was determined as % 0.11. Unilaterality ratio was % 63, and right-left distrubution was equal. AH was seen 1.3 times more in the male patients. The most frequent accompanying systemic diseases were hypertension (% 35) and diabetes (% 25). Only 3 (% 19) patients had presented with flying objects in front of eyes. Refraction was hyperopic in % 59 of eyes (13/22). The biochemical examination values did not differ significantly from the control group (p> 0.05). As a conclusion AH is usually detected accidentally during routine examination. In this study it is seen that AH might be related to diabetes but not with hypercholesterolemia, hyperurisemia and hypercalcemia. This condition in which most patients are asymptomatic rarely affects fundus examination and rarely decreases visual acuity.
