Intravitreal injections of anti-vascular endothelial growth factor agents such as ranibizumab and aflibercept are the first-line treatment for neovascular age-related macular degeneration (AMD). However, data about long-term outcome in real-world clinical practice is scarce. We recruited 98 AMD patients and investigated four-year visual outcome. During the four years, 25 patients dropped out. The survivors received 7.0 ± 0.1 injections during the first year and 8.0 ± 7.4 injections in the following three years...

BACKGROUND: Klebsiella endogenous endophthalmitis (EE) is commonly seen in patients with hepato-biliary disease and urinary tract infections. Subretinal abscess with vitreous cells is the usual presentation and requires intensive treatment with systemic and intravitreal antibiotics along with prompt vitrectomy. Subretinal hemorrhage surrounding a choroidal mass has not been reported as the presenting feature of endogenous bacterial endophthalmitis. METHODS: We report a patient with chronic liver disease who developed Klebsiella pneumoniae EE secondary to urinary tract infection that mimicked a choroidal neovascular membrane (CNVM) with subretinal bleed...

Choroidal tuberculoma is a solitary elevated choroidal mass-like lesion regarded often characteristic of intraocular tuberculosis. Serial swept-source optical coherence tomography (SS-OCT) is a very important tool in monitoring the course of choroidal tuberculoma and allows in early detection of complications such as choroidal neovascular membrane (CNVM). We describe a 26-year-old young Indian female, who presented with a solitary choroidal mass lesion in the left eye. Based on positive Mantoux test, biopsy of cervical lymph nodes showing acid-fast bacilli and radiographic findings, a diagnosis of choroidal tuberculoma was made...

Serpiginous choroiditis (SC) is an asymmetrically bilateral inflammation of the choroid that leads to loss of choriocapillaris atrophy or loss of overlying retinal pigment epithelium. Over the last few decades, SC has passed through a long evolution of nomenclature, etiologies and morphological variations. Initially diagnosed in patients with tuberculosis and syphilis, SC was predominantly considered as autoimmune process. With the advancement of molecular diagnosis, a new aspect of infectious subtypes of SC has emerged out...

A 75-year-old man presented with deterioration of right eye vision for 6 months. He had no relevant medical history. Fundus examination revealed subretinal fluid, fibrosis, and subretinal hemorrhages. Ocular coherence tomography of the right macula illustrated an underlying subretinal lesion with internal lamellae, resembling trabecular bone elsewhere in the body. Bruch's membrane was clearly intact beneath the lesion, indicating an extrachoroidal location. The lesion appeared highly reflective on B-scan ultrasonography, consistent with ossification...

Pseudoxanthoma elasticum (PXE) is an autosomal recessive multisystem disorder that involves the skin, GI tract, and heart, as well as the eye. It affects approximately 1 in 50,000 people worldwide and is seen twice as frequently in females as in males. Fundus findings include angioid streaks (Fig. 38.1), reticular macular dystrophy, speckled appearance temporal to the macula (peau d'orange, like the dimpled texture of an orange peel), drusen of the optic nerve, and vitelliform-like deposits. Peau d'orange may precede the development of an angioid streak...

This dominantly inherited disease begins with fine, pale, drusen-like deposits or confluent faint yellow material or sheets beneath the retinal pigment epithelium (RPE), but it eventually progresses to either geographic atrophy with pigmentary clumps or scar due to choroidal neovascular membrane (at about 40 years of age) (Figs. 20.1, 20.2 and 20.3). The patient usually becomes symptomatic, with loss of central vision (about 20/200 or less), in the fourth to sixth decade of life. When neovascular membrane develops, it mimics age-related macular degeneration (AMD), but the age of onset is much earlier...

In these conditions, drusen are present in childhood, but patients are asymptomatic, with good vision, until their 40s or 50s. Drusen are seen at the macula, around the edge of the optic nerve and/or nasal to the disc, in a radiating pattern (in particular, temporal to macula, as in Figs. 18.1, 18.2, 18.3, 18.4 and 18.5). The periphery is usually spared. Drusen increase in size and number with age. Peripapillary drusen are a characteristic finding. Visual loss later in life is due to pigment hyperplasia, geographic atrophy, and choroidal neovascular membrane (Figs...

Age-related macular degeneration (AMD) is one of the major causes of irreversible blindness among aging populations in developed countries and can be classified as dry or wet according to its progression. Wet AMD, which is characterized by angiogenesis on the choroidal membrane, is uncommonly seen but more severe. Controlling or completely inhibiting the factors that contribute to the progression of events that lead to angiogenesis may be an effective strategy for treating wet AMD. Emerging evidence has shown that transforming growth factor-β (TGF-β) signaling plays a significant role in the progression of wet AMD...

Combined hamartoma of retina and retinal pigment epithelium (CHRRPE) has been considered as a congenital benign entity with evidence of choroidal neovascularization membranes (CNVM) being associated with it in literature. This case series gives insight into the pathogenesis and the predisposing factors leading to CNVM formation in peripapillary CHRRPE using swept-source optical coherence tomography. In addition, lack of typical markers of CNVM (subretinal fluid/pigment epithelial detachment) in CHRRPE highlights the utility of optical coherence tomography angiography and the subtle optical coherence tomography findings such as "Bridge Sign" that could be instrumental in early diagnosis of CNVM in CHRRPE...
