RESUMEN
PURPOSE: To report the response of cavernous haemangioma of the disc to PDT. METHODS AND PATIENTS: A 32 years old lady presented to us with complaints of sudden onset of blurry vision in her right eye. What seemed initially as polypoidal choroidal vasculopathy turned out as cavernous haemangioma of the disc after pneumatic displacement of the sub-retinal haeme. She was treated with PDT as she was prone to recurrent haemorrhage from the lesion due to her low platelet count. RESULTS: Complete regression of the cavernous haemangioma was noted as early as the second week itself and remained regressed for 4 months. CONCLUSION: PDT can be safe option for patients presenting with symptomatic cavernous haemangioma of the disc or retina.

AIM: To study the effect of lanosterol on age-related cataractous human lens nuclei. MATERIALS AND METHODS: Forty age-related cataractous nuclei removed during manual small incision cataract surgery were obtained and randomly immersed in 25 mM lanosterol solution or in control solution and stored at room temperature for 6 days. Pre- and post-immersion photographs were graded by two masked observers and collated for the regression or progression of lens opacity. RESULTS: Both lanosterol and control groups showed progression or no change in the lens opacity at the end of 6 days. CONCLUSION: Lanosterol 25 mM solution did not reverse opacification of human age-related cataractous nuclei.
