The Khopoli intrusion is a small olivine gabbro intrusion exposed in the Konkan Plain, in the western part of the Deccan Traps continental flood basalt province. It intrudes lavas of the Neral and Thakurvadi formations, which belong to the lower part of the Western Ghats stratigraphic sequence and mainly comprise small-scale compound pāhoehoe flows and sheet lobes, respectively. Many of these lavas contain abundant cumulus olivine and clinopyroxene. The Khopoli intrusion is of considerable interest because its olivine gabbros are among the most magnesian Deccan rocks known, with bulk-rock MgO contents reaching 27 wt.%. Textural, mineralogical and geochemical features indicate that the olivine gabbros are olivine-pyroxene cumulates formed from an evolved tholeiitic basalt melt. Much of the original outcrop of the intrusion (mapped in 1980) is now lost owing to large-scale urban and industrial development. We have remapped the intrusion and obtained a 40Ar/39Ar age of 67.3 ± 1.5 Ma (2σ) on fresh intercumulus plagioclase grains separated from one of the olivine gabbros, which is consistent with the age of the host volcanic sequence. Measured true density values of 2.93 to 3.13 g/cm3 for olivine gabbros of the Khopoli intrusion suggest possible shallow causes for at least some of the high gravity anomalies found in the Deccan Traps.

A 60-year-old male presented with pain and decreased vision 3 weeks following uneventful intracapsular cataract extraction with anterior vitrectomy for subluxated cataract. A diagnosis of acute endophthalmitis was made based on clinical and ultrasound features. Patient improved only after undergoing pars plana vitrectomies twice and repeated intravitreal antibiotic-steroid injections. Vitreous aspirate revealed Gram-negative bacillus identified as Pseudomonas luteola on culture. Patient returned with a retinal detachment at first follow-up which was treated with vitrectomy, endolaser, and silicone oil tamponade. To the best of our knowledge, this is the first case of P. luteola causing acute onset, virulent endophthalmitis reported in literature. [ABSTRACT FROM AUTHOR]

A 23-year male with complaint of diminution of vision in left eye was referred to us as a suspect case of inflammatory choroidal mass/melanoma. Examination revealed a total retinal detachment with a reddish brown lesion in the superior hemi-fundus. B-scan ultrasonography demonstrated the 'mass' to be intra-retinal without choroidal involvement. A diagnosis of haemorrhagic intraretinal macrocyst (HIM) was made. We report this case to highlight the importance of correctly diagnosing an HIM and utilizing ultrasound to rule out choroidal pathologies, especially melanoma. This is essential as the management and prognosis of the two disorders is entirely different., Competing Interests: There are no conflicts of interest.
