  1. “ A Study of diagnostic use of BScan in evaluating vitreoretinal pathologies in blunt ocular trauma with media opacity in rural setting.” Dr. HIMANTO HAZARIKA DR. C. K. BARUA DR. P.K.GOSWAMI Dr. ROHIT.R.MODI REGIONAL INSTITUTE OF OPHTHALMOLOGY, GUWAHATI

  2. FINANCIAL DISCLOSURE This study was done by Regional Institute of Ophthalmology, Guwahati. The authors are consultants and have no direct financial interest in the above mentioned study.

  3. Introduction: Globally, it is estimated that 1.6 million cases of blindness are caused by eye injuries. WHO programme for the prevention of blindness, suggested that some 55 million eye injuries restricting activities of more than one day, occur each year. Ultrasonography (USG) has emerged in recent years as an useful technique for detecting and outlining the soft tissue abnormalities of the eye and orbit in ocular trauma. The first diagnostic application of ultrasound in ophthalmology was by Mundt and Hughes (1956). The experience about cross-sectional B-scan display of the eye was reported by Baum and Greenwood (1958).

  4. AIM To determine the use of BScan in diagnosis of vitreoretinal(VR) pathologies in blunt ocular trauma (BOT) with media opacity especially in rural setting.

  5. Materials and Methods: • A prospective study of 57 eyes of 57 patients was done between March, 2008 to August, 2008. • Age of the patients : 5-73 yrs • Number of male patients : 46 • Number of female patients : 11

  6. INCLUSION CRITERIA • History of blunt ocular trauma of various origin. • Presenting within one week. • Presence of media opacities : • Corneal haziness/edema • Hyphaema • Secondary cataract • Vitreous opacities. EXCLUSION CRITERIA • Globe rupture • Critically traumatized patients • RTA accidents • Coma/Unconscious patients • ICU admitted patients

  7. RESULTS • A total No. of 57 eyes of 57 patients were studied. • Male : Female ratio = 46 : 11 • Mean age of the patients : 25.2 yrs. • 47.4% of cases were below 20 years of age. • Male patients are more vulnerable to BOT.

  8. RD, PVD and Vitreous hemorrhage Choroidal Detachment

  9. PVD with subhyaloid hemorrhage. Vitreous Hemorrhage with PVD Retinal Detachment Dislocated lens into the vitreous

  10. DISCUSSION: • Of the 57 eyes studied, 50% of patients had history of BOT while playing with bat & ball, stick/wood, stone throwing and fist injury. • In a study by Babar et al. males constituted 79.66% and females 20.33%, by Khan et al. (84.7% versus 15.3%). In this study the ratio was found to be 80.7% versus 19.3%. • Saxenaet al. reported pediatric ocular trauma from New Delhi, India, were 133 (65.1%) boys and 71 (34.9%) girls. Babar et al. reported ocular trauma below 15 years as 351 (80.87%) boys and 83 (19.12%) girls.

Pattern of pediatric ocular trauma in India. Indian J Pediatr 2002; 69: 863-7

  11. contd........ • In our study 47.4% were below 20 years of which 23 (88.5%) boys and 3 (11.5%) girls. • Vitreous hemorrhage was found to be the commonest pathological posterior segment findings with 35 (61.4%) followed by PVD 15 (26.3%), Retinal Detachment 07 (12.3%), Subluxated lens 05 (8.8%) and hemorrhagic Choroidal Detachment 04 (7.0%). • Cases with subluxated cataractous lens, Retinal detachment, posterior globe rupture and other vitreoretinal pathologies were promptly managed accordingly.

Clinical use of ultrasound biomicroscopy. Ophthalmology 1991; 98: 287-295.]

  12. Conclusion: • BScan is an useful non-invasive diagnostic tool to evaluate Vitreoretinal Pathologies at an earlier stage in Blunt Ocular Trauma in rural setting. It helps in prompt referral of patient with VR Pathologies to higher centres. • As most of the patients belong to younger age group; USG assisted appropriate diagnosis and management, also helps in prompt referral and thus prevention of severe loss of vision. • USG should be considered as a routine procedure for all cases of BOT with media opacity in rural setting.
