In this paper, we review sexually transmitted diseases (STD) involving the eye. Recently conjunctivitis due to Chlamydia trachomatis in children and adults is increasing, and that of Neisseria gonorrhoeae resistant to multiple antibiotics has attracted special attention in our country. Syphilis has many ocular manifestations such as keratitis, iridocyclitis, retinochorioiditis, and neuritis, etc. Ocular complications related to HIV infection, including HIV retinopathy, cytomegalovirus retinitis, zoster ophthalmics, and Kaposi s sarcoma in conjunctiva are increasing in Japan. Phthirus pubis infection of the eye lid, and human T-cell lymphotropic virus type 1 (HTLV-1)-associated uveitis are occasionally reported. Furthermore conjunctival tumor associated with human papilloma virus (HPV) infection, acute retinal necrosis(ARN) due to herpes simplex virus type 2 (HSV-2), as well as hepatitis B virus (HVB) and hepatitis C virus (HVC) retinopathy are also mentioned in this review.

In 1959, 5-iodo-2'-deoxyuridine (IDU) was described, the first antiviral drug ever to be (and still) marketed (for the topical treatment of herpetic keratitis). Now 50 years following the description (of the synthesis) of IDU, we have 50 compounds on the market that have been licensed for clinical use in the treatment of virus infections. Of those 50, exactly 25 have been formally approved as anti-HIV drugs; the other 25 have been formally approved for the treatment of other virus infections: herpes simplex virus (HSV), varicella-zoster virus (VZV), cytomegalovirus (CMV), hepatitis B virus (HBV), hepatitis C virus (HCV), and influenza virus infections.

The efforts made to develop RNAi-based therapies have led to productive research in the field of infections in humans, such as hepatitis C virus (HCV), hepatitis B virus (HBV), human immunodeficiency virus (HIV), human cytomegalovirus (HCMV), herpetic keratitis, human papillomavirus, or influenza virus. Naked RNAi molecules are rapidly digested by nucleases in the serum, and due to their negative surface charge, entry into the cell cytoplasm is also hampered, which makes necessary the use of delivery systems to exploit the full potential of RNAi therapeutics. Lipid nanoparticles (LNP) represent one of the most widely used delivery systems for in vivo application of RNAi due to their relative safety and simplicity of production, joint with the enhanced payload and protection of encapsulated RNAs. Moreover, LNP may be functionalized to reach target cells, and they may be used to combine RNAi molecules with conventional drug substances to reduce resistance or improve efficiency. This review features the current application of LNP in RNAi mediated therapy against viral infections and aims to explore possible future lines of action in this field.

Purpose: To report a rare case of non-tuberculous mycobacterial (NTM) choroiditis masquerading as choroidal tumour, where the initial diagnosis was masked by keratitis. Case description: A 57-year-old heroin chaser with a pre-existing left eye blindness due to past blunt trauma presented with diffuse bacterial keratitis on the same side. Systemic examination revealed multiple non-tender cervical lymphadenopathies. B-scan ultrasonography showed a hyperechoic choroidal mass with surrounding exudative retinal detachment, resembling a choroidal tumour. However, computed tomography (CT) and magnetic resonance imaging (MRI) scan findings were suggestive of inflammatory choroidal changes. Inflammatory markers were significantly raised and infective screening was positive for HIV and Hepatitis C. Tuberculosis workup was normal. In view of intractable pain, evisceration was done and his vitreous humour was sent for polymerase chain reaction (PCR). It was reported to be positive for Mycobacterium Fortuitum. Conclusion: NTM ocular infections are rare, challenging to diagnose, and potentially sight threatening. Early recognition and prompt treatment is life and vision saving.
