Anterior and posterior segment examination was otherwise normal, apart from asteroid hyalosis
in the right eye.
Common findings included corneal fibrosis, cataracts, and asteroid hyalosis
. The most common ophthalmic abnormality in this species was cataracts.
Myopic vitreopathy and asteroid hyalosis
are also common causes of vitreous floaters .
Whether or not to replace a removed lens and the anatomic location of the new lens are decided based on surgeon experience, patient age, the condition of the posterior capsule, and the patient's other ocular pathologies (glaucoma, diabetic retinopathy, asteroid hyalosis
, low endothelial cell count, increased corneal thickness).
2] Posterior staphyloma in 4 cases [0.8%] [Fig 5], PVD in 6 cases [1.2%] [Fig 7], Asteroid hyalosis
in 4 cases [0.8%] [Fig 8], Vitreous opacities & exudates in 8 cases [1.6%] [Fig 3] Variation in Axial length of eyeball was found in 6 cases [1.22%], Coloboma choroid in 1 case [0.2%] [Fig 6] IOFB in one case [0.2%] [Fig 4].
Light rays from OCT can reasonably penetrate mild ocular media opacities like cataract, posterior capsular opacification, vitreous hemorrhage, asteroid hyalosis
One eye had asteroid hyalosis
noted before injection at the time of initial examination.
Silicone IOLs also exhibit a rare association with calcification of the optic and are thus contraindicated in patients with asteroid hyalosis
. There has been a recent debate on tendency for bacterial adhesion to silicone IOLs increasing the risk of endophthalmitis.

3), 2(1.26%) were retinal detachment with vitreous haemorrhage (Fig 4) while asteroid hyalosis
Severe asteroid hyalosis
obscured the fundus OD in 1 eagle (Fig 5).
They found that out of 73 scans performed, 48 eyes had vitreous haemorrhage 22 eyes showed inflame action in the vitreous and 3 eyes had asteroid hyalosis
out of 48eyes with vitreous haemorrhage, 34% had posterior segment pathology.
