Common findings included corneal fibrosis, cataracts, and
asteroid hyalosis. The most common ophthalmic abnormality in this species was cataracts.
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].

By far the most common cause of crystalline deposits in the vitreous gel is asteroid hyalosis (Figure 1).
Are there the crystals of asteroid hyalosis? Is there a significant haze?
3), 2(1.26%) were retinal detachment with vitreous haemorrhage (Fig 4) while asteroid hyalosis (Fig.
A lower incidence of asteroid hyalosis (0.73%) was noted in non-traumatic cataract patients as compared to that reported by Qureshi et al, [10] (1.77%) and Ali and Rehman, [7] (2.93%) in their study but higher incidence was noted as compared to other study, [9] (0.4%).
ULTRA SOUND B-SCAN FINDINGS: Out of 23 positive cases, 5 (2.5%) had retinal detachment, 5 (2.5%) had posterior vitreous detachment 6 (3.9%) had vitreous hemorrhage, 2 (1%) were asteroid hyalosis, while posterior staphyloma and intraocular foreign body were found with frequency of 2 (1%) and 1 (0.5%) respectively.
Incidence of asteroid hyalosis (1.10%) was noted in non-traumatic cataract patients, which was lower than reported by Ali & Rehman (2.93%) in their study.
vitreous hemorrhage, asteroid hyalosis, silicon oil were detected in 1 eye (1%) respectively.
(3) In asteroid hyalosis, calcium soaps produce bright echoes on B-Scan, (3) PVD produces a smooth membrane with low reflectivity whereas RD exhibits a more tethered and restricted after movement.
