This comparison clinical photograph depicts a case of anterior nodular scleritis of the right eye before and after treatment. Image (a) shows the eye in an acute inflammatory state, characterized by significant scleral and conjunctival injection (redness) and the presence of multiple, well-defined, yellowish-white elevated nodules located on the temporal sclera. Engorged episcleral blood vessels are clearly visible. Image (b) shows the same eye after two months of antitubercular therapy (ATT) and highly active antiretroviral therapy (HAART). The photograph demonstrates a marked clinical improvement, with a significant reduction in inflammation and conjunctival hyperaemia. The previously prominent nodules have largely regressed, leaving behind slight scleral thinning and residual grayish discoloration, indicative of healing and resolution of the granulomatous process. This visual comparison illustrates the efficacy of targeted systemic therapy in treating infectious nodular scleritis associated with tuberculosis and HIV coinfection.

This composite of ophthalmological images documents a clinical case of intraocular inflammation (IOI) following intravitreal brolucizumab injection. Panels A, B, and C are external clinical photographs of the right eye focusing on the superior sclera. Image A shows active, diffuse superior scleritis with intense vascular congestion and episcleral injection. Image B demonstrates clinical resolution of the scleritis following topical therapy, showing a white, quiet sclera. Image C illustrates a recurrence of the scleritis with marked conjunctival and episcleral hyperemia. Panel D includes a wide-field fundus photograph and a corresponding Optical Coherence Tomography (OCT) scan. The fundus image in D shows severe vitreous opacification (haze), obscuring retinal details, while the OCT B-scan displays poor signal-to-noise ratio due to vitreous media opacity, though a macular profile is visible. Panel E shows a follow-up wide-field fundus photograph demonstrating significant clearing of the vitreous opacity, allowing for a detailed view of the optic nerve head, retinal vasculature, and macula. This series illustrates the correlation between clinical scleritis and internal ocular inflammation (vitritis) as complications of intravitreal pharmacotherapy.

This composite diagnostic image presents a side-by-side comparison of the right eye using clinical photography and Optical Coherence Tomography (OCT) to illustrate the progression of anterior scleritis. Image A (Day 22) demonstrates active pathology: the clinical photograph shows significant scleral injection and localized redness, while the corresponding anterior segment OCT reveals structural disruption. Specifically, dashed arrows indicate separated scleral fibers, solid arrows highlight hyper-reflective inflammatory infiltrates, and an asterisk marks a region of irregular reflectivity within the scleral lamellae. Image B (Day 29) shows the clinical resolution: the external photograph displays a quiet eye with diminished redness, and the OCT scan demonstrates a more homogenous, compact tissue architecture with the disappearance of the previously noted infiltrates and fiber separation. This comparison serves as an educational tool for ophthalmology, specifically for monitoring the clinical and structural response to treatment in inflammatory ocular conditions such as scleritis.

This composite educational image features a clinical photograph and a diagnostic Optical Coherence Tomography (OCT) scan illustrating ocular inflammation.

(e) B-mode ultrasonography showing characteristic 'T-sign' (posterior scleral edema) and scleral thickening associated with extensive SRD. (f) Contrast-enhanced MRI (coronal view) revealing significant contrast enhancement localized to the posterior ocular wall (yellow arrow). This composite illustrates the typical progression and diagnostic findings for combined anterior and posterior inflammatory eye disease, highlighting key clinical features such as scleral melting, subretinal fluid, and optic disc swelling.

Clinical photograph (ophthalmic external/anterior segment) of the right eye showcasing anterior segment inflammation with conjunctival injection. Frontal view highlights diffuse bulbar conjunctival redness, greatest inferiorly, with adjacent vascular engorgement and mild episcleral whitening not clearly seen. The cornea shows no obvious defect in this frame, and the eyelids appear unremarkable. In the setting of Behçet disease, ocular involvement most often presents as noninfectious anterior uveitis or episcleritis, and can progress to vision impairment if undertreated. The observed redness and focal vascular congestion are findings compatible with active ocular surface inflammation and possible early keratouveitis, though histologic detail is unavailable in a photograph. This image captures a snapshot of inflammatory activity that informs clinical assessment of BD activity, helps distinguish autoimmune inflammatory processes from infectious conjunctivitis, and supports therapeutic decision-making regarding systemic immunomodulation and local therapy. Clinically, it complements other BD features such as oral/genital ulcers and skin lesions, and may prompt rheumatology consultation. In educational use, it illustrates differential diagnosis of acute ocular surface inflammation and the importance of monitoring response to treatment over time.

This composite educational image features a color photograph and corresponding Anterior Segment Optical Coherence Tomography (AS-OCT) scans of a right eye, illustrating clinical signs of nodular episcleritis and scleritis. The color photograph reveals marked violaceous ocular injection, superficial blood vessel congestion, and a localized nodular thickening approximately 4mm from the limbus. AS-OCT cross-sections (a) and (b) provide detailed visualization of the underlying tissue architecture. Key findings include nodular episcleral thickening (asterisk), a subepiscleral fluid level presenting as a hyporeflective space (black arrow), and intlamellar scleral edema (white arrow/asterisk). These OCT features correlate with the clinical appearance of vessel dilation and deep tissue inflammation. The image serves as a diagnostic reference for identifying inflammatory eye conditions using both external photography and non-invasive cross-sectional imaging, highlighting the relationship between visible clinical signs and internal structural alterations like scleral lamellae bisection by hyporeflective fluid.

This clinical photograph of a patient's right eye displays intense ocular inflammation and post-surgical complications. The primary findings include significant scleritis or episcleritis characterized by diffuse, deep-seated redness and engorgement of the episcleral and scleral blood vessels, obscuring the normal white appearance of the scleral tissue. The cornea exhibits notable corneal neovascularization, with fine, branching blood vessels invading the peripheral corneal stroma from the limbus. These vascular changes are concentrated adjacent to a visible surgical site, identified as a clear corneal incision typically associated with cataract surgery. The image illustrates educational concepts related to postoperative ophthalmological complications, specifically the inflammatory response and the angiogenic process following intraocular surgery. It serves as a diagnostic reference for identifying severe anterior segment inflammation and pathological vessel growth in a postoperative clinical setting.

This clinical photograph, captured via slit-lamp biomicroscopy, illustrates a focal scleral nodule in a patient with systemic sarcoidosis. The image focuses on the anterior segment of the eye, specifically the bulbar conjunctiva and underlying sclera. The primary feature is a well-circumscribed, elevated, pinkish-red nodular mass. Surrounding the lesion is intense episcleral and conjunctival injection, characterized by dilated, tortuous blood vessels radiating towards the nodule, indicating significant localized inflammation and vascular engorgement. The central portion of the nodule appears slightly paler than its hyperemic periphery. This finding represents a rare ocular manifestation of sarcoidosis, showcasing granulomatous infiltration of the sclera. Key educational concepts include the identification of inflammatory scleral lesions, differentiating episcleritis from nodular scleritis, and recognizing ocular markers of systemic granulomatous diseases. The image is a valuable diagnostic reference for ophthalmologists and rheumatologists managing multi-system inflammatory conditions.

This clinical photograph shows a close-up of a patient's right eye during a medical examination, illustrating significant conjunctival and scleral injection. The primary finding is marked diffuse erythema over the bulbar conjunctiva, characterized by engorged and prominent blood vessels across the scleral surface. The intensity of the vascular injection is most pronounced at the medial canthus (inner corner) and the inferior aspect of the globe. The cornea remains relatively clear with visible iris details, and there is no obvious purulent discharge, suggesting an inflammatory rather than infectious etiology. Surrounding structures, including the eyebrow, eyelashes, and skin tone, appear normal. The lower portion of the frame shows an examiner's gloved hand and surgical mask, providing clinical context. This visual is representative of ocular manifestations associated with systemic inflammatory conditions, such as the extraintestinal manifestations seen in Crohn's disease or other forms of episcleritis/uveitis.

This composite of four clinical photographs illustrates various stages and complications of necrotizing scleritis associated with Granulomatosis with Polyangiitis (GPA). Figure A displays an acute phase of necrotizing scleritis in the right eye, characterized by intense episcleral and scleral vascular congestion and localized areas of bluish discoloration indicating scleral thinning. Figure B shows similar active necrotizing scleritis in a left eye with diffuse hyperemia and haziness. Figure C demonstrates a severe complication of the disease process: significant superior scleral melt with subsequent uveal prolapse, visible as a dark, bulging mass where the scleral integrity has been lost. Figure D shows the postoperative appearance of the same eye following surgical intervention with a scleral patch graft to repair the defect. The graft is visible as a white, opaque tectonic support material integrated into the superior globe, with surrounding conjunctival injection and visible sutures. These images serve as educational examples of the destructive potential of systemic vasculitis on ocular collagenous tissues and the necessary surgical management of scleral perforation.

Clinical photograph of the anterior segment of the right eye demonstrating severe necrotizing scleritis. The image shows marked, diffuse episcleral and scleral vascular congestion (hyperemia). Two distinct areas of scleral melt are visible: one in the temporal quadrant indicated by a black arrow, and a second, newer focal area of melting in the superonasal quadrant indicated by a yellow arrow. The areas of melting appear as regions of significant scleral thinning and tissue loss, with irregular borders and associated yellowish-white necrotic debris. This clinical presentation is characteristic of advanced autoimmune-mediated or infectious scleritis, indicating a high risk of ocular perforation. The surrounding conjunctival tissue is intensely injected, reflecting an active, severe inflammatory process.

Clinical photograph of an eye under cobalt blue light illumination after fluorescein staining, illustrating conjunctival and scleral pathology. The image displays a focal area of bright green fluorescein uptake, signifying conjunctival erosion and epithelial defect. This irregular, elongated region of fluorescence is located over a section of markedly white, avascular sclera, indicative of scleral thinning or melting. Within the affected zone, small, punctate white spots are visible, consistent with calcium deposits. The surrounding conjunctival tissue appears relatively hypovascular, with visible but sparse perilimbal vessels. This finding is clinically relevant in the context of necrotizing scleritis or surgically induced scleral necrosis (SINS), demonstrating the loss of tissue integrity and the characteristic 'melting' appearance associated with chronic inflammation or ischemia of the ocular surface.
