    Abstract Purpose: To describe a young male with bilateral sequential Cytomegalovirus retinitis (CMVR) as the presenting feature of Dyskeratosis Congenita.
    Case report: A 25-year-old human immunodeficiency virus (HIV) negative male developed CMVR in his left eye, while on a three week course of oral valganciclovir therapy for CMV retinitis in his right eye. Systemic examination revealed reticular hypopigmentation of the forearms, dystrophic nails, oral leukoplakia and complete blood counts showed pancytopenia. A diagnosis of Dyskeratosis Congenita was confirmed with genetic testing.
    Conclusion: CMVR in non-HIV individuals should be considered as a harbinger of systemic immunosuppressive conditions. Ophthalmologists may be the first ones to suspect and diagnose congenital immunosuppressive disorders like Dyskeratosis Congenita in these patients.

    Abstract Corynespora cassiicola is an environmental phytopathogen implicated in various human infections and has been isolated from one case of keratitis. We report here the first case of endophthalmitis caused by Corynespora cassiicola in a 54-year-old diabetic patient, who developed diminished vision, redness, and watering in the right eye, six weeks after intravitreal triamcinolone acetonide for non-proliferative diabetic retinopathy and macular oedema. Direct microscopy of the vitreous tap revealed septate hyphae, and culture grew white mycelium that turned olive-grey to black within two days and was confirmed as C. cassiicola after sequencing of the ITS region of 28S rDNA. The patient was started on oral voriconazole 200 mg twice a day. The patient is on regular follow-up without recurrence. To our knowledge, this case represents the first case of endophthalmitis due to this fungus across the globe and the first case of C. cassiicola infection from India.

    Abstract Purpose: To assess the utility of pre-defined imaging biomarkers on optical coherence tomography (OCT) and OCT angiography (OCTA) in patients with diabetic macular edema (DME) following anti-vascular endothelial growth factor (anti-VEGF) therapy in determining visual and anatomical outcomes.
    Methods: In this prospective, non-randomized, and interventional study, 17 patients with treatment-naive DME were included. OCT biomarkers [size/reflectivity of cysts, disorganization of retinal inner layers, integrity of ellipsoid zone or external limiting membrane, subfoveal serous retinal detachment, hyper-reflective foci (HRF)] and OCTA [vascular density (VD), foveal avascular zone (FAZ), and total micro-aneurysms in superficial capillary plexus and deep capillary plexus (DCP)] were analyzed at baseline and after three monthly intravitreal anti-VEGF injections. Response was defined as a decrease of 10% or more in central macular thickness from the baseline after three injections.
    Results: 13/17 (76.47%) patients were categorized as responders to anti-VEGF therapy. Non-responders had significantly greater hyper-reflectivity of cysts (P = 0.015), larger cystic spaces (P = 0.023), and an increased number of HRF (P = 0.04) at baseline. On OCTA, non-responders showed larger FAZ in DCP (1.35 ± 0.21 versus 1.14 ± 0.28 mm2) (P = 0.042) and lower VD (61.17 ± 0.45 versus 62.73 ± 3.32) in DCP at baseline. At 3 months, the VD increased in responders (63.10 ± 3.42) compared to a decrease in non-responders (60.82 ± 1.13) (P = 0.032).
    Conclusions: Non-responders show a higher number of micro-aneurysms, larger FAZ, and lower VD in the DCP on OCTA and higher cyst hyper-reflectivity and HRF and larger cystic spaces on OCT imaging.
